Sexy Topics

Certain topics have a propensity to appear in the Final Examination. Some are topical, some are even newsworthy, and some have been done badly in previous exam sittings. Is it worth trying to spot some questions? Absolutely; we successfully managed to 'guess' 3-4 questions in the last exam, so I'm going to list a few topics which I think may come up for various reasons.

Previous SAQs done badly as highlighted in the Examiner's Report
- Preop assessment of a hypertensive patient (October 2007 SAQ paper)
- Management of twins (October 2007 SAQ paper)
- Air Embolus (April 2008 SAQ paper)
- Paediatric Fluid Balance (April 2008 SAQ paper)
- Neuromuscular Blocking Reversal + Sugammadex (April 2008 SAQ paper)

Other topics include issues of public interest and patient safety which were highlighted in the Examiner's report as being repeatedly done badly and therefore will continue to be represented in the examination, guidelines (including AAGBI, NICE, NPSA), and review articles from major journals.

-Awareness: continually remains in the public eye
-Healthcare-associated infections (VIP cannula scores/MRSA/C.Diff): huge at present also linked with recent publication by the aagbi on Infection in Anaesthesia
-CEMACH - easily repeated question
-Mental Capacity Act - has come into force in late 2007. This is the link I used previously, but for much more comprehensive coverage of both this and issues of Consent, EI has done a fantastic job putting togther some very simple explanations of tricky topics!
-LA toxicity +/- Intralipid use - it's going to come up eventually
-Malignant Hyperthermia treatment
-Blood Transfusion
-Perioperative Management of the Morbidly Obese Patient
-Prophylaxis against Infective Endocarditis: NICE March 2008
-Perioperative hypothermia: NICE April 2008
-Head Injury: NICE September 2007
-VAP: NICE August 2008
-CEPEX testing here
-POISE (Perioperative Ischaemic Evaluation) study: looks at beta-blocker use in non-cardiac surgery
-Amniotic Fluid Embolism: inexplicable rise in last triennium of CEMACH report.
-Obesity in Pregnancy

The Written Paper

SAQs
For candidates sitting the exam for the first time, the SAQ section can seem the most daunting of the two. This style of exam has not been approached or attempted before (except in my case - wry laugh at onesself!). Adam has highlighted in his recent posting on Exam Intelligence the importance of layout of your SAQs. As you can see from his jpeg examples, it makes a huge difference to the examiner marking the paper. One little tactic is to try and put yourself in the examiner's shoes: you have 60 or 70 copies of the same question to mark, you're probably going to get a bit bored after a while - it's human nature. It must be intensely irritating to arrive at a question that you can't read, or is squashed against the far margin (or is irrelevant!). So, here is some SAQ advice:

- Learn to write nicely - make it larger and well spaced-out. Start practicing now - don't wait until the day.
- Be relevant; answer the question asked. It sounds obvious but you'd be surprised. You only get approximately 10-12 minutes to write the question (plus two-three minutes planning). Don't waste time on lengthy definitions/introductions if not asked for.
- Use diagrams - as mentioned in a previous posting, an accurately-labelled diagram may save you a lot of time and gain more marks than a block of prose.
- Get your timing right - this section of the exam is time-pressured. Work out your strategy of answering questions i.e. do you work through the paper sequentially making a question plan then answering the question, or do you make plans for all questions in the paper, then answer them? You must have a game-plan thought out.
- If you haven't already started, time your questions...strictly! You have to complete all 12 questions in 3 hours; that's 15 mins per question. Anyone who has done the exam before will tell you it is exhausting and they're right. To write solidly for 3 hours is difficult, both on your hand and on your mind. Like running a marathon, you need to train for it, and build up your stamina in answering these questions. Start by answering 4, then 6, then 8, then 12 questions in a row...timed!

MCQs
A word of warning, ignore these at your peril. There is a tendency to concentrate on the SAQ section, thinking that past experience in MCQs will see you through. This is the mistake I made and I paid for it with a 1+ and that is part of the reason why I have the privilege of doing this again. I probably can't offer much in the way of new advice on how to be successful with MCQs - everyone has quite extensive experience. Do as many MCQs as you can lay your hands on. The only difference this time around is that negative marking has been removed and consequently the pass mark will increase. You should probably be aiming to achieve approximately 80% i.e. average of 4/5 on each stem.

HCAI

At the beginning of August, I didn't know what HCAI stood for. I certainly do now: healthcare-associated infections. As mentioned previously, this is big business in the NHS. As usual, there are mountains of paperwork associated with this, including lots of webpages which, if you have loads of free time on your hands and not a lot to do, you could trawl through. However, we have exams, therefore we need a concise summary of what is important to us as anaesthetists/intensivists for the Final FRCA. Below is an account which summarises and provides links to important guidelines/publications:

Saving Lives - Clean Safe Care
- In a nutshell, the aim is to reduce HCAIs and provide safe, clean, reliable healthcare.

Important Publications
- Winning Ways (Chief Medical Officer, Dec 2003): strategy for reducing HCAIs in UK.

- Towards cleaner hospitals & lower rates of infection (DoH, July 2004) - 6 elements:
1) Being open with the public i.e. regular publication of infection data
2) Giving power to the patients e.g. cleanyourhands campaign.

***On September 2nd, the NPSA released a Patient Safety Alert 'Clean Hands Save Lives'. The four page document can be downloaded from here.***

3) A matron's charter - ten principles for delivering cleaner hospitals
4) Independent inspection to measure progress
5) Learning from the very best i.e. home & abroad
6) Harnessing the latest research & technology

-Saving Lives (June 2005): a delivery programme for acute hospitals to reduce HCAIs using Essential Steps to Safe, Clean Care e.g. reducing MRSA strategies, preventing inter-patient contamination, urinary catheter care, enteral feeding infection risk education.

- Also of relevance to anaesthetists/intensivists are: High Impact Interventions (or Care Bundles). Important ones include:

a) CVC care
b) Peripheral intravenous cannula care (also see later)
c) Care for ventilated patients
d) Reducing the risk of Clostridium.difficile

- Going Further Faster II (June 2008): applying the learning to reduce HCAI and improve cleanliness. A long document incorporating recent national guidelines/aims in infection control.

In my trust, there is a new policy which aims to ensure that all peripheral cannulae are sited in an aseptic manner. There is also routine use of Visual Infusion Phlebitis charts/scoring. Information can be found here and here.

AAGBI

The Association of Anaesthetists' updated guidelines on Blood Transfusion and the Anaesthetist in June 2008 are available now online. They are well worth a read and should be part of core knowledge both in clinical practice and for the forthcoming exam.

Guidelines from organisations such as the Association of Anaesthetists, as I have mentioned previously, provide excellent exam topics as they are current and relevant. In the interest of being thorough, the Association also published Standards of Monitoring in March 2007. Whilst this should be second nature to us as anaesthetists and, indeed, common sense, there are important clinical guidelines highlighted.

Spring Clean

As you may have noticed, there are a few extras added to the site. As I have been so utterly fed up with revision in the past day or two, I reverted to the ultimate in procrastination and found some fun stuff to put on the blog. I realise that for the majority of time, I hope I'm posting some useful information/links etc about hot topics. Some of my friends who read this blog tell me that it gives the impression that I'm constantly working extremely hard and am very well prepared. You'll be delighted to hear that in fact I am completely human and some days really struggle to open a book. Like today....!! So, I hope that this posting will bring some comfort to everyone who has crap days where the brain is resisting attempts to revise.

There is a live traffic feed on the bottom left margin to see where everyone is coming from and going to via this site - if you feel this is a infringement on your privacy, you are able to opt your browser out by clicking on the options button at the bottom of it. No-one gets any personal information from you - it's purely an interest thing for the geek in me!

Only 40 days to go until the written - chins up!

Make your life easy!

'A picture is worth a thousand words' (Fred R Barnard 1921)

The above quote can be applied to many parts of this exam, most specifically to anatomy. There will be an anatomy/regional technique SAQ and there will be an anatomy SOE. With that type of guarantee, one must be well prepared and learn thoroughly the anatomy syllabus. If you can produce a slick, well-labelled diagram, it looks impressive to the examiners and you will earn many more marks than trying to write a block of anatomical prose or talk through the roots of the lumbar plexus! I speak from experience, having 'come a cropper' in the anatomy section of my science viva (I will try to follow my own advice next time!).

My former exam buddy Dr B (FRCA) had a great method for anatomy and graph revision; he used a white board and continually drew and re-drew the diagrams, whilst talking to himself about what he was drawing as if explaining to the examiners. It then became second nature to reproduce what was required within seconds.

I used two textbooks for my revision: Anatomy for Anaesthetists & Concise Anatomy for Anaesthesia. I also used AnaesthesiaUK, Instant Anatomy, New York School of Regional Anesthesia, and Google Images. So what do you need to know? Well, basically all of the Primary syllabus but in a clinically-orientated manner. So, not just "Draw the brachial plexus" but "Describe with the use of a diagram which nerves are blocked with an interscalene block. Tell me how you would perform the block, and what are the contraindications/complications".

Below is a list of stuff you should know from head to toe - not definitive but should cover the majority of the syllabus:

Cerebral circulation
Cranial Nerves
The Eye: Clinical = blocks
Nerve supply to the face: Clinical = trigeminal neuralgia
Nose: it has been asked in the past!
Internal Jugular & Subclavian Vein: Clinical = cannulation
Cervical plexus and here: Clinical = superficial/deep cervical plexus blocks (+ GA vs RA for carotids)
Neck surface anatomy: Clinical = tracheostomy (+ surgical vs perc + cross-section @ C6)
Stellate ganglion: Clinical = block
Brachial plexus: Clinical = block
Axilla
Ulnar/radial/median nerves: Clinical = blocks (from BP to wrist)

Larynx and here: Clinical = LA/RA for awake fibreoptic intubation
Tracheobronchial tree: Clinical = one-lung anaesthesia/DLT
Pleural space: Clinical = intercostal N block/interpleural block/paravertebral block
Coronary circulation: Arterial & Venous
Epidural space: Clinical = epidural anaesthesia
Subarachnoid space: Clinical = spinal anaesthesia
Vertebrae: Clinical = as above/vertebral space
Spinal cord and here: Clinical = arterial blood supply

Autonomic Nervous System: so many questions!! ?Valsava manoeuvre
Coeliac plexus: Clinical = block
Lumbar plexus: Clinical = block (+ lumbar sympathetic block)
Sacral plexus
Sacrum: Clinical = Caudal anaesthesia (usually paediatric)
Femoral Triangle: Clinical = '3-in-1' blocks
Femoral Nerve: Clinical = as above
Sciatic Nerve: Clinical = blocks (different approaches)
Nerve supply to foot: Clinical = ankle block

It's hot out there...

A quick posting to draw your attention to the recently published NICE guidelines (August 2008) on:

Technical patient safety solutions for ventilator-associated pneumonia in adults

There was an SAQ in May 2005 on VAP, so perhaps time for a revisit??
These will be the last set of NICE guidelines published before the exam setting mid-September.

Anyone else finding the hot weather difficult to revise in?? ;)

STOP PRESS!!

The word on the street is all about reducing Hospital Acquired Infections. Anyone who has attended a hospital induction this month will have been bombarded by both the corporate, clinical, and departmental teams regarding the importance of limiting infections. Never before in my career have I witnessed such emphasis on one particular area. Heck, I even had to attend mandatory training on taking blood cultures and inserting cannulae (and have the certificate to prove it - so proud!).

Why is this huge? Apart from the obvious continual negative media attention reveived with daily uproar (and obviously the detrimental effect on patients - how could I forget to mention this?!), this is big bucks for the hospitals. There will be financial penalties for those Trusts failing to comply and suffering high HAI rates.

How does it affect us? Well, apart from changing our clinical practice, it may save us £690. Why? Because (Yes, I know I've started a sentence with 'because'; pedants!) of it's extreme topical nature, it could be a Short Answer Question, or even appear in the Structured Oral section of the exam. I refer you to Exam Intelligence who has already alerted readers of his blog as to the potential of this line of questioning. He outlines what the Royal College have said - we need to be aware of topical issues, and none is hotter than this at the moment. More information can be found on the Clean, Safe Care NHS website.

This is emphasised this month, as if by magic, by our beloved Association of Anaesthetists in the publication of updated guidelines on Infection Control in Anaesthesia (September 2008 edition of Anaesthesia p.1027). This is a must-read as it is concise, topical, and most importantly, relevant to anaesthesia.

ICU-itis

My ICU shifts recently have been so hectic and busy that I've not had a chance to participate in the sport of Academia at Olympic levels recently! I have started ploughing through Elfituri & Arthur's MCQ book - with a resounding 76% in the first paper - I was quite pleased at that, although I still seem to make the same mistakes as I did the last time I attempted the paper. I had also worked my way through the October 2007 SAQ paper, and will share some more ideas about this paper later in September.
Although the workload has been heavy, I've had some opportunities to put some Final's knowledge to good use. I encountered a chap on the medical ward last night whose K+ was 8.9 (and still alive) - even post-treatment, his broad complex ECG made for a sphincter-tightening journey to ICU!! The question on life-threatening hyperkalaemia (?October 2007) seemed quite appropriate all of a sudden. I also brightened up my evening with a failed intubation on ICU (unexpected Grade 4 laryngoscopy: Consultant-confirmed. They usually subtract 1 from what the trainee makes the grade!!) - thank you to Archie Brain for the provision of the LMA.

I've got some days off coming up soon, and hope to summarise a few more topics related to the exam. If anyone has any topics which they feel are relevant, or not covered well in textbooks - please share by leaving some comments, or emailing me (jrs970@yahoo.co.uk)

Down Under...

As well as roaring past the 2500 hits mark, the blog has been recommended on an Australian website: Anaesthesiacases

They write: "James Shorthouse’s Blogspot!! This is great reading: the keeping of a diary in the approach to the final FRCA exam. Good for the final exam candidate but also for the consultant browsing on a range of clinical topics". I'm thrilled to have received some international recognition!!

Back to the job in hand: having just finished a stupendous ten day stretch in ICU, I've been trying to catch up with some revision. I've just filled out my application form for the exam, together with a(nother) cheque for £690. Remember that the closing date is September 9th.

I've been through and repeated the SAQ paper I did in April this year, specifically concentrating on questions which were done badly by candidates i.e. air embolism, paediatric fluid resuscitation, and neuromuscular blockade reversal. All questions were done to a strict 10-11 minute time-limit, and I reviewed my answers and annotated them for further reference.

I have also completed the 270 MCQs in the new RCOA guide to the Final FRCA, in 3 batches of 90. Pleasingly, I managed to score 77%, 78%, and 79% respectively (aiming for 80% passmark). Bear in mind, some of these questions I've done before. On a negative turn of events, I attempted some Q-Base 5 questions on the computer. Firstly, I think in future I will do these Q-Base MCQs on paper as the CD-ROM only do negative marking. Secondly, they are in batches of 60, so you get out of sync with the papers - I believe we need to be practicing 90 MCQs at a time. Thirdly (& less importantly), there's something I really don't like about Q-Base questions i.e. they're hard and I only got 36% this time round! Just like last time, I always end up swearing at the computer during Q-Base!!!

Sugamma.....something or other

The only reason I had heard of this prior to the SAQs in April was because one of my previous bosses, who I did regular lists with as an SHO, was fascinated by it and would discuss it regularly - amazing to think that even a couple of years later those 'discussions' would be useful to me! So what's all the fuss about?

Sugammadex (AKA 'The Molecular Condom' as described by gaussling)



Company

Codenames
- Org 25969
- Modified γ-cyclodextrin


Structure
- Lipophilic core and hydrophilic periphery enabling the molecule to engulf and bind lipophilic molecules while maintaining aqueous solubility (8 negatively-charged thio ether extensions are situated at the 6th carbon position of each ring, thus extending the cavity size allowing greater encapsulation of the rocuronium molecule).

Mechanism of action
- The first selective relaxant binding agent - it forms very tight water-soluble complexes at a 1:1 ratio with aminosteroidal neuromuscular blocking drugs e.g. rocuronium, preventing them from binding to the ACh molecule and exerting muscular relaxation.

Uses
- Reversal of profound neuromuscular blockade without the need to inhibit acetylcholinesterase i.e. eliminating the autonomic/CVS effects of the more traditional acetylcholinesterase inhibitors(neostigmine) and the concomitant antimuscarinics (glycopyrrolate) that must be also administered. (Phase 3 trials)
- Elimination of the incomplete reversal experienced with use of traditional acetylcholinesterase inhibitors.
- Also, the rapid onset (and now reversal by Sugammadex) of action of rocuronium could make it a safer alternative to suxamethonium in rapid sequence inductions.

Pharmacodynamics/Pharmacokinetics

- No effects on other receptor systems in body i.e. biologically inactive
- Does not bind to plasma protein
- No renal excretion

Is it Pimms o'Clock yet?

Exam Intelligence has a spanking sparkly new website up and running now - if you haven't already checked it out, it's definitely worth bookmarking for the breadth and sheer effort put in by Adam in providing valuable information to pass this exam.

My website skills are minimal but what I will continue to try and achieve is a regular update of both my revision progress (poor at present - anyone else feeling a bit lethargic in the hot weather?) and useful information, links etc.

Someone emailed me recently asking for advice about SAQs. RCOA have just produced their report on the April SAQ paper. This, in my opinion, is a great revision aid alone. It gives a unique insight into what the examiners expect from the SAQ answers.

Here are some thoughts:

-"Despite the questions being printed in the answer books, a small number of candidates failed to
answer all the questions." You will fail if you don't answer all the questions - that is expensive and time-consuming!!

-"Questions: 3 (air embolus), 4 (paediatric fluid balance) and 7 (neuromuscular blocking reversal) caused the most problems to candidates" Something to think about for next time maybe?

-"Question1 (paravertebral space) was generally well done but few candidates did a really good
anatomy section. The diagrams were especially poor – examiners assumed this was due to lack of knowledge." A diagram (even simple but well labelled) will get you a lot more marks and take less time than a block of prose.

-"Whilst the web sites related to the FRCA are mostly useful and enjoyable, there are occasional
moments when it is disappointing to see unhelpful advice being offered. This particularly relates to generic answers and, for example, it is rarely the case that a whole ‘pre, per and post op’ structure would facilitate a good answer on the SAQ paper.... It cannot be emphasised enough that the answer provided to the examiners is less than a page and is focused completely to the question." This is a fair point: as my experience of writing SAQs has grown, I have realised that there is no time for a complete generic answer. Whilst it can give you structure, usually in a viva, in the SAQs the answer has to be much more specific. In theory, you should be able to pass the question writing between one to two A4 sides of concise and relevant bullet points/labelled-diagrams. Paragraphs are unsightly, difficult to mark, and a waste of time that you do not have.

Out of the blocks...True or False?

Since adding a counter to the website approximately two weeks ago, over 1000 people have had a look - many thanks. Feel free to leave (constructive) comments, and if there are any suggestions please either comment or email me: jrs970@yahoo.co.uk

I started work again yesterday with great difficulty and attempted upsurges in motivation. Actually quite an encouraging start: I began with the MCQs from the new edition college book, some of which I recognised from previously, and some which were new. It's a different ball game with MCQs from now on without the negative marking, as this takes the dilemma about leaving questions unanswered out of the game. All questions should be answered as there is nothing to lose, and the college is recommending 80% as a passmark (which is probably the equivalent of approx. 60% for the negatively marked paper). I got 77% on the first 90 questions - don't be too alarmed as I have done the damn exam before so hopefully would have retained some knowledge. The last time I started MCQs, I was getting dreadfully embarassing marks e.g. 20-30%!! My advice would be: do not underestimate this part of the exam - it is where I came unstuck at my peril. Practice practice practice.

It is also worth (if not already done so) thinking about courses. Not for everyone, granted, but they do focus the mind somewhat (and it's a weekend/week off work too!). My experience is entirely with the Mersey courses. I can't recommend the Booker Course highly enough for the experience, practice, timing, and lectures on SAQs -it really whips you into shape! There are also various weekends/weeks for SAQs/MCQs, and SOEs once you hopefully get there.
Other courses available can be found at Anaesthesia UK.

NPSA

Reducing the risk of hyponatraemia when administering intravenous infusions to children

-Since 2000, there have been four child deaths following neurological injury from hospital-acquired hyponatraemia reported in the UK.

Recommendations
-Remove 0.18% NaCl with glucose 4% from stocks & general use in areas treating children.
-Produce local clinical guidelines for the fluid management of paediatric patients.
-Provide adequate supervision and training for all staff involced in the prescribing, monitoring, and administering of IV fluids for children.
-Review & improve design of existing drug prescription/fluid balance charts.
-Promote reporting of hospital-acquired hyponatraemia incidents

Resuscitation: intravascular volume depletion should be managed with 0.9% NaCl boluses
Deficit: estimate fluid deficit & replace as 0.9% NaCl with 5% dextrose or 0.9% NaCl over a minimum of 24hrs
Maintenance: do not use 0.18% NaCl with glucose 4%

The majority of children may be managed with 0.45% NaCl with 5% glucose (or 2.5% glucose)

CEMACH (report summarised in previous blog posting)

Journals

Thanks to everyone who is visiting the site - I now have a little counter to the left to get an idea of readership. It first went up about two weeks ago, and I've had nearly 800 views (thanks to Mum for all of them!).

As I have mentioned previously, the review articles in our journals (BJA & Anaesthesia) provide some ideal SAQ/SOE hot topics for the exam. It is important to recognise that there are some subjects much more likely to appear in an exam setting than others e.g. remifentanil as apposed to mitochondrial disorders! I estimate that approximately a year and a half's worth of articles are covered, so everything from April 2007 - September 2008. I have made what I consider to be exam topics in bold type:

BJA: here & here

2007
April: Blood flow & ventilation in the lung / percussion pacing
May: CA stents in non-cardiac surgery
June: Diastolic heart failure
July: Neuro ++! The whole post-grad issue is neuroanaesthesia/NICU reviews

For the mothers

I know it came up in the April 2008 SAQs, but it's still a hot topic so here it is again:

CEMACH 2003-2005 Summary


Definition
- Confidential Enquiries into Maternal Deaths.
- The longest running "Gold Standard" audit in the world. First Report covered 1952-54
- Triennial report published by DOH looking into all maternal deaths in UK
- Changed title from “Why Mothers Die” to “Saving Mothers’ Lives”.
- All maternal deaths: 14 per 100000 maternities (no statistically significant change).
- Direct maternal mortality: slight rise (not statistically significant).


Causes of death:
- Direct: deaths of women while pregnant or within 42 days of termination of pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not accidental or incidental causes.
- Indirect: deaths resulting from previous existing disease, or disease that developed during pregnancy and which was not due to direct obstetric causes, but which was aggravated by the physiological effects of pregnancy.
- Late: deaths occurring between 42 days and one year after the end of pregnancy


Risk Factors contributing to maternal death
(Essentially the same as the lack of decline of maternal mortality)

- Lack of preconception care i.e counselling & support especially for serious physical/mental comorbidities, obesity, assisted reproduction/fertility, and identification of vulnerable/high risk mothers.
- Lack of access to antenatal care
- Migrants (poorer overall health, no medical review, genital mutilation)
- Increasing age of mothers
- Increasing incidence of obese mothers
- Increasing incidence of comorbidities e.g. DM/CVS disease
- Poor lifestyle e.g. smoking/drinking/drugs


Commonest direct causes of maternal death

1) Thromboembolism (again)
=2) Pre-eclampsia/sepsis
4) Amniotic fluid embolism
=5) Haemorrhage/early pregnancy

- Increased numbers of: pre-eclampsia, genital tract sepsis/trauma + inexplicable rise in amniotic fluid embolism.
- Decreased haemorrhage/early pregnancy/ectopic.
- Nil of above: statistically significant.

Commonest indirect cause of maternal death
- Cardiac disease (less healthy diets, smoking, alcohol and the growing epidemic of obesity).

Anaesthetics
- 150 cases reviewed: direct or indirect cause of death also having anaesthetic

Direct anaesthetic deaths:
- 6 deaths – (4.5%) 0.28 per 100000 maternities. Same as previous triennium.
- All but one: Caucasian.
- 4/6: obese (2 were morbidly obese: BMI > 35)

Cases
1) Post-op bronchospasm & resp failure: obese asthmatic lady – failed reintubation during recovery post laparascopic surgery for ectopic pregnancy. Irreversible cardiac arrest.

2) Obese lady, early pregnancy, trainee anaesthetist. High-dose opiate given prior to extubation. In recovery developed respiratory difficulties. Inadequate ventilation, bradycardia, cardiac arrest.

3) Morbidly obese asthmatic lady, elective LSCS, spinal anaesthesia. Post-op agitation and SOB. Fatal cardiac arrest on post-op ward with inadequate resuscitation equipment.

4) Low-dose infusion epidural during labour & forceps delivery. PPH + IVI + syntocinon infusions. Grand mal convulsion + VF arrest – unable to resuscitate. Given 150mls 0.1% bupivacaine IV.

5) Lady with pectus excavatum in mid-pregnancy: â foetal movements, fulminant PET, & HELLP. Hypertensive, hyperreflexic, oliguric, & abnormal LFTs – given labetalol, Mg, & hydralazine. For urgent LSCS: RIJ cannulation unsuccessful but subclavian cannulation successful on the second attempt. Cardiac arrest shortly afterwards – large right haemothorax.

6) Obese woman with longstanding renal problems requiring nephrectomy. Had premature labour and delivery. A few weeks later, she was admitted with fever, loin pain, and ileofemoral venous thrombosis. Planned for drainage of septic focus from remaining kidney under U/S guidance. Pt refused LA and suffered an irreversible cardiac arrest during GA.

Indirect Anaesthetic Deaths

-Further 31 cases where poor perioperative anaesthetic management may have contributed to outcome

- Failure to recognise serious illness

- Poor management of haemorrhage (including syntocinon use): Less than optimum anaesthetic management contributed to many of the 17 maternal deaths from haemorrhage (12 died from PPH).

- Sepsis: Poor anaesthetic management/resuscitation was thought to have contributed to 10 maternal deaths from sepsis (usually failure to appreciate seriousness of maternal condition).

- Pre-eclampsia/eclampsia: 4 women died in relation to poor anaesthetic management (usually related to poor control of systolic blood pressure at time of LSCS/post-operatively)

- Management of obese pregnant women

- Quality of in-house hospital Trust enquiries into serious untoward incidents including maternal deaths: some reports of internal hospital enquiries sent to CEMACH were lacking in insight, improperly conducted, did not include clinicians from relevant specialties, or included clinicians involved directly with the maternal death (potential bias).

More Reading Material

Previous SAQ papers can be downloaded from the RCOA website here.

AnaesthesiaUK has many many past questions divided into various sections from here and here.
I have grouped all the questions according to SAQ, Long Cases, Short Cases, and Basic Sciences.

I would also look at the CEACCP supplements from 2007-8 that come with the BJA every other month. These topical subjects are excellent SAQ/SOE fodder. If you haven't got hard copies, they can be downloaded here, although you will need to sign in with your BJA subscription details.

The Bulletins from the RCOA can also be a useful source of information, again these can be downloaded from here.

Review articles from the BJA provide exam material too, using archives from 2007 and 2008.

Similarly, review articles from Anaesthesia, using archives from 2007 and 2008. Again, you will need membership details to access these.

Hope this provides some needed direction; there's still more to come!!

Buy a library

There are certain essential materials in my opinion which are invaluable for this exam:

Download a copy of the syllabus and use this to break your revision up into topics

Order a copy of the new guide to the FRCA Final Examination. As with the Primary version, this has examples of questions from all sections of the exam. The MCQ section is particularly useful as it is taken from the actual college bank and some do appear in the exam.

Opinion is divided as to whether to use a large textbook or not e.g. Aitkenhead, Pinnock, Hutton etc. This is a personal opinion and one which can be decided by previous experience for Primary and browsing before trying. Candidates will need to purchase/borrow some specialist text-books - many can be ordered from AnaesthesiaUK here or from Amazon. Here is a list I found useful:

General
"Companion to Clinical Anaesthesia Exams (FRCA Study Guides)"Charlie Corke
"Clinical Notes for the FRCA (FRCA Study Guides)"Charles Deakin

MCQ
"Final FRCA: Multiple Choice Questions (FRCA Study Guides)"Michael D. Brunner
"QBase Anaesthesia: MCQs for the Final FRCA v. 5"Edward Hammond
"MCQs for the Final FRCA"Khaled Elfituri
"MCQ's in Anaesthesia (FRCA Study Guides)"A. Ganado
"QBase Anaesthesia: MCQs for the Anaesthesia Final FRCA v. 2 (QBase)"Mark Blunt
"FRCA: MCQs for the Final FRCA: Saunders Self Assessment Series: MCQs for the Final FRCA (FRCA Study Guides)"Karen Henderson
"Practice MCQ's for the Final FRCA (FRCA Study Guides)"Jon Hardman

SAQ
"Anaesthesia & Critical Care" Chris Dodds & Neil Soni
"Short Answer Questions and MCQs in Anaesthesia and Intensive Care"Peter Murphy
"Short Answer Questions in Anaesthesia"Simon Bricker;
"Final F.R.C.A.: Short Answer Questions"J. Nickells

SOE
"The Anaesthesia Science Viva Book" Simon Bricker
"The Clinical Anaesthesia Viva Book"Simon J. Mills

Of course, the A to Z comes in handy too.

Let's have a date

OK, there is just under four months until the MCQ/SAQ paper which is on Tuesday 21st October. Hopefully people have started to revise by now, the big decision of whether to take the exam comes shortly as the opening date for entry is this Friday 4th July. We have until Tuesday 9th September to get the application (& money!) in - probably best not leave until the Monday!

Quite importantly, the paper is set on Tuesday 16th September, meaning that any topical subjects generally for the SAQ and SOE are fair game in journals up to September 2008. I will highlight these as we get nearer the time.

A New Beginning

Congratulations to everyone who passed the exam last week - it was no mean feat at all! Unfortunately, I was not successful for a number of reasons; I got a 1+ in the MCQ section which left me on a handicap going into the vivas. I got 2's in the SAQ and Clinical Viva, but had a major hiccup in the Science Viva - I got asked about the intercostal nerve etc and started off OK but then completely blanked. It spiralled downwards from there unfortunately. I thought I had rescued it in pharmacology, talking about conscious sedation & drugs etc, physiology was OK on oxygen delivery, but I appeared to struggle on physics and the Venturi effect of all things. It was a good example of letting an earlier bad section get to me. In hindsight, I should have done more MCQs!! It has been one of the toughest weeks of my career so far, but thanks to some great girlfriend/family/friend/work colleague support, I'm doing OK.

I decided that, despite having been an extremely public humiliation via this blog's reasonably wide stretching and advertising on AnaesthesiaUK, I would carry on blogging. Firstly, I hope it will give heart to others who weren't successfull this time, that they aren't alone in suffering; and secondly, because I know the information I have shared on this blog has helped people - and I hope to continue to do the same for the next batch of people.

You can read my previous efforts in their entirety at an alternative blogsite (I will transfer some relevant stuff from there): http://didntpassthefinal.blogspot.com.
