MC157 [Mar10] New Q
An 18 yo with Fontan Circulation undergoing exploratory laparotomy. On ICU vent, sats 70%. Which ventilator parameter would you INCREASE to improve his sats?
A. Bilevel pressure
B. Expiratory time
C. Inspiratory time
D. Peak inspiratory pressure
E. PEEP

D. Pheo
"Management of anesthesia in patients with von Hippel-Lindau disease must consider the possible presence of pheochromocytomas" (Stoelting)

von Hippel-Lindau disease (VHL) is a rare, genetic multi-system disorder characterized by the abnormal growth of tumors in certain parts of the body (angiomatosis).
The tumors of the central nervous system (CNS) are benign and are comprised of a nest of blood vessels and are called hemangioblastomas (or angiomas in the eye). Hemangioblastomas may develop in the brain, the retina of the eyes, and other areas of the nervous system.
Other types of tumors develop in the adrenal glands, the kidneys, or the pancreas.

Symptoms of VHL vary among patients and depend on the size and location of the tumors.
Symptoms may include headaches, problems with balance and walking, dizziness, weakness of the limbs, vision problems, and high blood pressure. Cysts (fluid-filled sacs) and/or tumors (benign or cancerous) may develop around the hemangioblastomas and cause the symptoms listed above. Individuals with VHL are also at a higher risk than normal for certain types of cancer, especially kidney cancer.
Inheritance = Familial Autosomal dominant
Features= Retinal angiomas, Haemangioblastomas, Cerebellar and visceral tumours (usually benign but can cause pressure effects)
Associations = An increased incidence of Phaeochromocytoma - apparently 20%, Renal cysts, Renal cell carcinoma

Anaesthesia= Treat hypertension occurring with phaeochromocytoma, Haemangioblastoma of spinal cord may limit use of spinal although epidural has been used for LSCS, Exagerrated hypertension with surgical stimulation or laryngoscopy = Treat with β blockers and/or SNP

From recollection, Phaeos are associated with the Diseases of Von- Ie. Von Recklinghausen and Von Hippel Lindau.
MH59 70 year old post TKJR. On sub-cut heparin. Develops clinical DVT and platelets 40 (sounds like HITS type-II). Management
A. Enoxaparin
B. Fondoparinux
C. Heparin by infusion
D. Lepirudin
E. Warfarin
Ans D
ME45 Hypercalcaemia
A. Chovostek's sign
B.
C.
D.
E. Short QT
Ans: E
Effects of hypercalcaemia: "Stones, Bones, Groans, Thrones and Psychiatric Overtones"
Stones (renal or biliary)
Bones (bone pain)
Groans (abdominal pain, nausea and vomiting)
Thrones (sit on throne - polyuria)
Psychiatric overtones (Depression 30-40%, anxiety, cognitive dysfunction, insomnia, coma)

Abnormal heart rhythms can result, and ECG findings of a short QT interval and a widened T wave suggest hypercalcaemia. Significant hypercalcaemia can cause ECG changes mimicking an acute myocardial infarction. Hypercalcaemia has also been known to cause an ECG finding mimicking hypothermia, known as an Osborn wave.

A. Do case while taking both.
B. Do case while stopping both.
C. Stop Prasugrel for 7 days, keep taking aspirin.
D. Stop Prasugrel for some other different time
E. Post-pone for 6 months
Ans E

ACC/AHA Pre-op:
DRUG ELUTING:
Thrombosis of DES may occur late and has been reported up to 1.5 years after implantation, particularly in the context of discontinuation of antiplatelet agents before noncardiac surgery.

Discontinuation of antiplatelet therapy in the early-surgery group resulted in a 30.7% incidence of MACE (all fatal) versus a 0% incidence in early-surgery patients who continued dual antiplatelet therapy perioperatively. Overall, there was no difference in MACE between patients with bare-metal stents and those with DES. The study reported that all patients with MACE had discontinued antiplatelet therapy before surgery, whereas only 46% without MACE had done so. The study also stated there was no difference in surgical risk between patients in whom antiplatelet agents were discontinued and those in whom they were not. Excessive blood loss occurred in 2 patients, 1 of whom was receiving antiplatelet agents and 1 of whom was not.

** The panel concurred with the AHA/ACC guideline recommendation for 12 months of dual-antiplatelet therapy after DES implantation in patients who are not at high risk for bleeding.
**1. Before implantation of a stent, the physician should discuss the need for dual-antiplatelet therapy. In patients not expected to comply with 12 months of thienopyridine therapy, whether for economic or other reasons, strong consideration should be given to avoiding a DES.

BARE METAL:
A thienopyridine (ticlopidine or clopidogrel) is generally administered with aspirin for 4 weeks after bare-metal stent placement. The thienopyridines and aspirin inhibit platelet aggregation and reduce stent thrombosis but increase the risk of bleeding. Rapid endothelialization of bare-metal stents makes late thrombosis rare, and thienopyridines are rarely needed for more than 4 weeks after implantation of baremetal stents. For this reason, delaying surgery 4 to 6 weeks after bare-metal stent placement allows proper thienopyridine use to reduce the risk of coronary stent thrombosis; then, after the thienopyridine has been discontinued, the noncardiac surgery can be performed. However, once the thienopyridine is stopped, its effects do not diminish immediately. It is for this reason that some surgical teams request a 1-week delay after thienopyridines are discontinued before the patient proceeds to surgery. In patients with bare-metal stents, daily aspirin antiplatelet therapy should be continued perioperatively. The risk of stopping the aspirin should be weighed against the benefit of reduction in bleeding complications from the planned surgery. In the setting of noncardiac surgery in patients who have recently received a bare-metal stent, the risk of stopping dual-antiplatelet agents prematurely (within 4 weeks of implantation) is significant compared with the risk of major bleeding from most commonly performed surgeries.

Guilbert M-C, Elkouri S, Bracco D et al. Arterial trauma during central venous catheter insertion Case series, review and proposed algorithm. J Vasc Surg 48:918-985, 2008

Postponing elective surgery will ensure that the anesthetized patient is not having an unrecognized stroke. Kron and colleagues recommend postponing elective open-heart surgery after two patients suffered serious complications when surgery was performed immediately after removal of the misplaced large sheath.

Complications with catheter removal and compression
1. Massive stroke and death
2. AV fistula require surgical repair
3. Pleural effusion, lung collapse require thoracic surgery to repair arterial hole and lung decortications
4. Hematoma and uncontrolled bleeding requiring open surgery to repair jugular vein and carotid artery

D. is formed from the lateral, medial, and posterior cords of the brachial plexus
E. provides sensation to the ulna half of the palm
Ans A
TMP-115 Patient for total knee replacement under spinal anaesthetic. Continous femoral nerve catheter put in for post op pain relief. Good analgesia and range of motion 18hrs post op. 24hrs post op, patchy decreased sensation in leg and unable flex knee. What is the cause?
A. Compression neurapraxia (i think it said due to torniquet)
B. DVT
C. Muscle ischaemia
D. Damage to femoral nerve
E. Spinal cord damage
Ans A
Inability to flex the knee is not a femoral nerve problem - it is sciatic. This problem seems to have clinical onset at about 24 hours.
A: True. It is possible to be due to compression neurapraxia by tourniquet.
B: False: DVT does not cause neurological symptoms
C. Muscle ischaemia is unlikely to happen post 24 hours for knee replacement.
D. False: The symptoms is more sciatic
E False, generally bilateral distribution

A. Continue with surgery
B. Beta block then continue
C. Get myocardial perfusion scan
D. Postpone surgery awaiting AVR
E. Postpone surgery awaiting balloon valvotomy
A - not severe and symptoms only on exertion

ACC/AHA 2007 guideline on perioperative cvs evaluation and care for noncardiac surgery
In symptomatic aortic stenosis, elective noncardiac surgery should generally be postponed or cancelled. Such patients require aortic valve replacement before elective but necessary noncardiac surgery.

If the aortic stenosis is severe but asymptomatic, the surgery should be postponed or cancelled if the valve has not been evaluated within the year.
On the other hand, in patients with severe aortic stenosis who refuse cardiac surgery or are otherwise not candidates for aortic valve replacement, noncardiac surgery can be performed with a mortality risk of approximately 10%.
If a patient is not a candidate for valve replacement, percutaneous balloon aortic valvuloplasty may be reasonable as a bridge to surgery in hemodynamically unstable adult patients with aortic stenosis who are at high risk for aortic valve replacement surgery and may be reasonable in adult patients with aortic stenosis in whom aortic valve replacement cannot be per-formed because of serious comorbid conditions.
TMP-112 (similar to above) Patient for fempop bypass (i believe it said "angioplasty"), history of CCF. Also has diabetes on oral hypoglycaemics, controlled hypertension and atrial fibrillation at rate of 80bpm .

TMP-107 Baby with TracheoOesophageal Fistula found by bubbling saliva and nasogastric tube coiling on xray. Best immediate management?
A. Bag and mask ventilate
B. Intubate and ventilate
C. position head up, insert suction catheter in oesophagus (or to stomach?)
D. Place prone, head down to allow contents to drain
E. Insert gastrostomy
A - FALSE. Not unless the baby is in respiratory distress and/or hypoxic. May inflate stomach by ventilating through fistula.
B - FALSE. Just because the baby has been diagnosed with TOF is not an immediate indication for intubation in and of itself.
C - TRUE. Neonates with TOF should have a "nasogastric" tube inserted into the oesophageal stump to drain secretions and prevent accumulation in the blind-end pouch. The NGT should be connected to continuous suction. The infant should be nursed prone or in the lateral position with 30 degrees head up tilt to decrease the risk of aspiration. See A Practice of Anesthesia for Infants and Children - 4th edition by Cote, Lerman, Todres; p.755. Saunders (2009)
D - FALSE. Can nurse prone, but lateral with head up tilt seems to be the recommended and most commonly cited method.
E - FALSE. Initial management as above (see C - TRUE), and then repair. Gastrostomy may be performed, but not best immediate management.
TMP-108 A 60yo Man with anterior mediastinal mass, during induction for mediastinoscopy....lose cardiac output, decreased saturations, drop in ETCO2. Management
A. Adrenaline
B. CPR
C. CPB
D. Place prone
D

Ans D
Management of the patient with a large anterior mediastinal mass: recurring myths
Curr Opin Anaesthesiol 20:1-3 2007

Should try wake up the patient.
Intraoperative life-threatening airway compression has usually responded to one of two therapies:
1. Repositioning of the patient (it should be determined before induction if there is one side or position that causes less symptomatic compression)
2. Rigid bronchoscopy and ventilation distal to the obstruction (this means that an experienced bronchoscopist and rigid bronchoscopy equipment must always be immediately available in the operating room during these cases).

For patients with life-threatening cardiovascular compression after induction that does not respond to lightening the anesthetic the only therapy is immediate sternotomy and surgical elevation of the mass off the great vessels.

Ans B
EV18 Desflurane TEC6 vaporiser, unable to turn dial on. This is NOT because
A. vapouriser is tilted
B. Hotter than 39C
C. On battery power
D. Interlock not engaged, or not seated properly (or something like that)
E. other vapouriser is already on
Answer is B
 The TEC 6 desflurane vaporizer needs to warm up and the "operational" LED light needs to be illuminated before you can turn the dial to the ON position. If you try to turn it on before the "operational" light is on it will not work. I assume that any of the alarms which cause the "operational" light to go off (and subsequently halt delivery of desflurane) mean that if you turn the dial to 0% (i.e. OFF) then you will not be able to turn it back on, but I have not read that anywhere. According to Graham (BJA 1994; 72:470-73), causes of vaporizer shutdown include:
 a tilt of about 10 degrees or more - although extremely unlikely given the design
 excessive tilting of the vaporizer activates auditory and visual alarms and causes cessation of desflurane output...Pharmacology of Inhaled Anaesthetics, p212
 it will not work on battery power
 the 9-volt battery does not supply the heaters with power or maintain the vaporizer in an operational mode...Pharmacology of Inhaled Anaesthetics, p212
 the vaporizer will not work unless locked into the selectatec mount, and the selectatec mount will not allow the use of multiple vaporizers simultaneously
 nb. note the "Tec" refers to the use with the Select-a-Tec manifold
PI83 Desflurane vaporiser, heated because of
A. High SVP
B. High boiling poing
C. Low SVP
D. High MAC
E. Low MAC

Group consensus that Australian answer is probably best
SF89 Most likely change on CTG with anaesthesia for non-obstetric surgery at 32 wks
A. Loss of beat to beat variability
B. No change
C. Late decels
D. Variable Deccels
E. uterine contractions
A
Evidence based practice of anaesthesiology (Fleischer)under conditions of very light sedation most narcotics and general anaesthetics decrease or obliterate long and short term FHR variability , hence one is left monitoring changes in baseline FHR.

A. 27%
B. 32%
C. 42%
D.
E.
Ans A
Based on the 'rule of nines', the estimated burn surface area would be as follows:
- half of upper arm = approx 2%
- all of left leg = 18%
- anterior abdomen = approx 9% depending on what proportion is burnt; whole thorax/abdomen on either anterior or posterior is 18% - i.e. 36% for front and back
-> TOTAL = 29%

D. Paternalism
E. Futility
C
47.Inserted DLT. FOB down tracheal lumen. What feature is most helpful in identifying Left vs Right main bronchus
A. Trachealis muscle
B. "there are 3 lobes in right lung"
C. LMB longer than right
D. Angle of RMB vs left
E. Three segments of RUL
A - False. Trachealis muscle divides at carina and continues in each main bronchus, so not particularly helpful. Trachealis was only located posteriorly connecting the ends of the C-shaped cartilage.
B - False. While there are indeed 3 lobes in the right lung, that fact is not helpful to determine which is right or left main bronchus.
C - True. The LMB is about 5cm long before it gives off any subsequent lobar bronchi, whereas the RMB gives off a lobar bronchus (the RUL bronchus) about 2.5cm from the carina. This can help to determine between RMB and LMB.
D - False. While there is a difference in the angle (from the vertical) of the LMB and RMB, I don't know if this would be significantly appreciable bronchoscopically.
E - True. The RUL bronchus has a trifurcation for each of the RUL segments, and this may also be useful in determining which side you are on.
48.You are performing a bronchoscopy, but are unsure of your location. Then you see trifurcation of bronchi. Most likely location is:
A. Right upper lobe
B. Right Middle Lobe
C. Right lower lobe
D. Left lower lobe
E. Lingula
Ans A
A true trifurcation is where the RUL bronchus divides into segmental bronchi.
PC50 Elimination Half life of Tirofiban
A. 2hrs
B. 8hrs
C. 12hrs
D. 24hrs
E. 15 minutes
A
50.POISE trial showed
A. Increase CVA
B. Anaphylaxis
C. renal failure
D. Increased AMI
Answer is A
51.Why is codeine not used in paeds
A. Poor taste
B. High inter-individual pharmacokinetic variability
C. Not licensed for <10yo
D. not as effective as adult when given in ?weight adjusted dose?
B - TRUE. Variations in CYP2D6 function affect how much codeine is converted to morphine, and therefore how effective it is, but also how "sensitive" patients are to codeine.
52.Patient on table for phaeochromocytoma with GA and epidural insitu. Pt on phenoxybenzamine and metoprolol preop, high dose nitroprusside and phentolamine. BP still high ?250/-. Next step
A. IV hydralazine
B. IV Magnesium
C. Propofol
D. Epidural lignocaine bolus
E. Esmolol
A - FALSE. Duration of action may be a problem, as once tumour is out you may need a vasopressor and won't want the hydralazine hanging around. Plasma half-life is 2-3 hours (significantly more in renal impairment, but may be less in "rapid acetylators"). Anyway, 4 half-lives is 8-12 hours (less if you're a fast acetylator.
B - TRUE.
C - False. Not the best option.
D - False. Epidural bolus will not negate the effects of circulating vasoactive catecholamines.
E - False. Esmolol for tachycardia, but not for BP control.
53.25 yo primip ?38/40 gestation with beta thalassemia trait for epidural. BP 140/95, mild proteinuria ...something else... Best test before you will put in epidural
A. Coagulation screen
B. Hb
C. Platelet count
D. skin bleeding time
E.
Answer is C. Thalassemia trait is a red-herring. No effect on clotting/epidural placement. Money is on pre-eclampsia Main thing to look at is the platelet count.
See Oxford Handbook 2nd edn - p.744.
- If plt>100, proceed.
- If plt<100, do coags.
- If plt 80-100, and coags normal - regional is OK.

B. IV hydralazine
C. IV Magnesium
D. insert epidural
Ans B

By definition she has SEVERE pre-eclampsia.
A - False. Although they are usually intravascularly deplete, IV fluids should be given cautiously as these women are prone to develop pulmonary oedema. Volume expansion alone can reduce SVR and systolic BP. Oliguria should be treated with careful IV fluid challenge. The BJA CEACCP article (see below) states that a bolus of 250ml crystalloid should be given, but if no improvement (in urine output) a CVC should be inserted before any further fluid given. Then be guided by CVP and urine output. Crystalloid decreases plasma oncotic pressure, while colloids increase it and have a greater tendency to cause pulmonary oedema. However, if CVP low, can use colloid. I say false because 500ml is probably a bit too large as a bolus initially.
B - TRUE. Initial management should aim to reduce the BP. This is the best of the options, although the CEACCP article also states that careful volume expansion should precede the use of vasodilators, so as not to drop the BP too much. That is not one of the options though, and I think this is the best option.
C - False. Initial attempts to reduce BP and improve urine output should probably precede Mg administration. Anyway, giving someone with minimal urine output a large bolus of IV Mg increases the chances of Mg toxicity. Should give IV fluids before giving Mg.
D - False. Epidurals are desirable in pre-eclampsia but in severe pre-eclampsia you should try and reduce the BP first, and always check the platelet count +/- coags BEFORE placing epidural.

A. Morphine
B. Phenytoin
Ans B

Reference: [1] and Harper's Illustrated Biochemistry
Suggest B-Phenytoin but morphine while safe to use but will not be used to treat a convulsion so make sure you read the question...
Treatment of seizures in porphyriacs is a difficult situation given that most anticonvulsants are contraindicated (such as phenytoin, carbamazepine, thiopentone) because they induce hepatic P450 enzymes. (This consumes heme and thus reduces the negative feedback on ALA synthesase which is then free to generate heme/porphyrins products.) Drugs considered safe to use in convulsing porphyriacs include: midazolam, propofol, gabapentin and magnesium.

B. TTE
Ans A
Transthoracic echocardiography (TTE) is easily available and the ascending aorta and aortic arch can be visualized well. In obese or chest trauma patients, image quality may be inadequate due to poor echo windows. Transoesophageal echocardiography (TOE) has become more popular as experience and availability increase. It is useful perioperatively in the haemodynamically unstable patient. TOE images the entire thoracic aorta except for the most distal ascending aorta and a part of the arch obscured by the trachea or right main bronchus. Echocardiography can be used with high accuracy for decision-making in acute dissection.

B. post op myocardial ischaemia
B
From Landesberg G: The Pathophysiology of peri-op MI: the facts and perspectives. J Cardiothoracic and Vac Anaes 2003: 17(1): 90-100
Peri-op myocardial ischaemia peaks in the early post-op period and is significantly associated with MI and cardiac complications. Intraop ischaemia is less common and infrequently associated with post-op MI. Peri-op MI is almost exclusively preceded by ST depression type ischaemia. (STEMI is uncommon)
Peri-op MI is mostly silent (only 50% have any sx) and occur in first 24-48 hours post-op pick with cont. ECG monitoring and ST trend analysis and troponin.

Ans A
Cohort studies: A longitudinal study where some cases are exposed and the others are not. They are followed up and the incidence of disease in each pup compared. Almost always prospective but it is possible to perform a cohort study entfre1y retrospectively. Risk analysis often with relative risk or odds ratio.

Case control studies: The disease status is know and a retrospective analysis is made to determine whether there was a difference in exposure to risk factors. Risk analysis with odds ratio.
Risk: the number with an even divided by the total number at risk of the event.
Odds: the number with an even divided by the number without.
Relative risk: ratio of the risk of an even between the two groups

Above if it was a cohort study:
RR: 50/75/(25/50)=1.333
OR: (50:25)/(25/25) = 2

This is a retrospective case control study. Patient with complication were identified and matched to look at the exposure. Therefore, you can’t define an incidence rate and therefore not able to calculate RR. However, you can still calculate an odds ratio.

A. Class 1 device
B. Equipotential earthing
C. LIM
D. Residual Current Device
E. Fuse
Ans D
CEACCP electrical safety in the operating theatre

A. Class 1 Device: Any conducting part of Class I equipment accessible to the user, such as the metal casing, is connected to earth by an earth wire. If a fault occurs, this allows the live supply to come into contact with an accessible part, current flows down the earth wire. This new circuit has a lower resistance, resulting in an increased current which melts the protective fuses and breaks the circuit, removing the source of potential electrocution.
B. Equipotential earthing: the terminals of each piece of equipment in a stack can be connected to each other bringing them all to the same potential.
C. Line isolation monitor: measures the potential for current flow from the isolated power supply to the ground. i.e. active and neutral should have the same current. If there is a fault, a device is grounded then the current through to neutral would decrease. There is then a current able to flow through the line isolation monitor and sounds an alarm.
D. Residual current device: If the current in the live and neutral conductors is the same, the magnetic fluxes cancel themselves out. However, if they are different (due to excessive current leakage) there is a resultant magnetic field. This induces a current in the third winding causing the relay to break the circuit.
E. Fuse: a material that melts with increased current and breaks the circuit.
