Miller's



Central Subclavicular Lead


The central subclavicular (CS5) lead is particularly well suited for the detection of anterior myocardial wall ischemia. The right arm (RA) electrode is placed under the right clavicle, the left arm (LA) electrode is placed in the V5 position, and the left leg electrode is in its usual position to serve as a ground. Lead I is selected for detection of anterior wall ischemia, and lead II can be selected for monitoring inferior wall ischemia or for the detection of arrhythmias. If a unipolar precordial electrode is unavailable, this CS5 bipolar lead is the best and easiest alternative to a true V5 lead for monitoring myocardial ischemia.

Pontine Myelinolysis


Rapid correction of sodium in hyponatremia would cause the extracellular fluid to be relatively hypertonic. Free water would then move out of the brain cells to decrease this relative hypertonicity. This leads to a central pontine myelinolysis, manifesting as the paralysis. The brain appears to shrink.


The demyelination of the axons (nerve fibers in the brain) damages them.

122. Reasons infants desaturate faster than adults on induction (?did it say rapid sequence?)



A. More difficult to preoxygenate
B. More rapid detection of hypoxia
C. FRC decreased more than adults
D. Drugs work more rapidly
E. Persistent L->R shunt (or was it right to left?)


Answer: A?



CEACCP Basic Principles of Anaesthesia for Neonates and Infants 2001 - Higher oxygen consumption, greater ratio of alveolar ventilation to FRC, same FRC but closer to closing volume = rapid desaturation on cessation of ventilation

125. Adenosine would be useful for terminating which arrhythmia?



A. AF
B. Atrial Flutter with variable block
C. Torsades
D. VT
E. WPW

Answer E.



WPW

Oxford Emergencies in Anaesthesia pg 506 - Adenosine slows conduction through the AV node, therefore is useful in terminating SVTs including WPW. May differentiate between SVT and VT

126. Induction with thio 5mg/kg, scoline 2mg/kg, Difficult to open mouth, Finally intubated. Next step:

A. Continue surgery with tiva propofol
B. Abandon surgery
C. Wait for co2 to rise restart surgery after 30 min
D. Continue with inhalational agents
E. Give calcium as potassium may have raised

Answer A or ?B, depending on nature of "difficulty" and surgery

Controversial.



OEIA / CEACCP 2003 / MHAUS - If emergency surgery should continue with non-MH triggers i.e., TIVA. If elective, safest to abandon surgery pending further investigation.
Only 20-30% with sole symptom of masseter spasm develop MH

127. In a patient with an intra-orbital haemorrhage, following local anaesthetic injection, the adequacy of ocular perfusion is best assessed by:



A. angiography
B. direct ophthalmoscopy
C. indirect ophthalmoscopy
D. intra-ocular pressure tonometry
E. palpation of the globe by an experienced clinician

Answer B

Controversial past question, which seems to have caused a lot of upset amongst candidates. Very few published sources but a lot of anectdotal reports. Have cut and pasted this summary from Blackbank:

A. angiography - fluoroscein angiography would be gold standard, but time consuming to organise
B. direct ophthalmoscopy - provides 15x magnification to allow a view of the fundus is required to look for central retinal artery or vein occlusion. General consensus is that the essential clinical diagnosis depends on the viewing of a pulsatile artery by this method.
C. indirect ophthalmoscopy - gives a wider field of view but less magnification than direct. Given ischaemia due to pressure is an issue, ?greater assessment of the retina would be preferable.
D. intra-ocular pressure tonometry - helpful, but diagnosis is clinical. Pressure may be raised but if arterial and venous supply are intact, it's not going to change management
E. palpation of the globe by an experienced clinician - additional pressure will compromise what is already potentially a tenuous blood supply.

128. A patient is in Class IV Haemorrhagic Shock, secondary to a gunshot wound to the abdomen. He is clinically coagulopathic 30 minutes later. He has received intravenous Hartmann's 1L. The coagulopathy is likely related to:

A. acidosis
B. dilution of clotting factors
C. hypothermia
D. systemic release of tissue factor
E. tissue hypoperfusion

Answer: E



Acidosis, hypothermia and trauma induced coagulopathy are the lethal triad of major haemorrhage following trauma but Acute Trauma Coagulopathy is independent of resuscitation efforts
CEACCP 2014 - “Trauma patients were coagulopathic on arrival at the emergency department (ED) and the incidence of coagulopathy increased with severity of injury independent of the volume of pre-hospital resuscitation fluid. Those who arrived coagulopathic had an increased mortality compared with non-coagulopathic patients. This coagulopathy is termed acute trauma coagulopathy (ATC) and is another mechanism of coagulopathy under the umbrella term of TIC. The mechanisms of ATC are yet unproven but appear to be related to tissue hypoperfusion, leading to up-regulation of the vascular endothelium and subsequent alterations in coagulation pathways. This coincides with massive activation of coagulation with consumption of clotting factors, noticeably factor V and fibrinogen, activation of the Protein C pathway, and increased fibrinolysis”

129. (Repeat) A 20 kilogram child suffered 15% full thickness burns 6 hours ago. Optimum crystalloid resuscitation for the first hour is:

A. 160ml
B. 260ml
C. 360ml
D. 460ml
E. 660ml

Answer C

Parkland formula = 4ml/kg/day x %BSA with half in first 8 hours (CSL) from time of burn



4 x 20 x 15 = 1200ml / 2 = 600mL in 8 hours, but only 2hrs remaining so 300ml/hr



Mainentance IVF = 4ml/kg/hr for 1st 10kg, 2mg.kg/hr for next 10kg, 1ml/kg/hr for remaining kg (N/2 + 5%)
40 + 20 = 60ml/hr



Total = 360ml/hr

130. You’re anaesthetizing an otherwise well 40 yo male for a craniotomy. Propofol and remifentanil TIVA. Using entropy. The MAP is 70 mmHg, heart rate is 70 bpm, Sats are 98%, state entropy is 50 and the response entropy 70. Most appropriate next step is

A. give 0.5 mg metaraminol iv
B. use NMT to assess train of four ratio
C. change to volatile anaesthetic
D. do nothing
E. increase propofol TCI concentration by 0.5

B



Response Entropy may be picking EMG interference, hence check TOFR and treat accordingly.

131. The normal physiological response following ECT is:



A. transient tachycardia followed by bradycardia and hypotension
B. transient bradycardia followed by tachycardia and hypertension
C. unpredictable
D. transient tachycardia followed by bradycardia and hypertension
E. tachycardia and hypotension

Answer B



Millers pg 2477 - Initial PNS discharge: bradycardia, potential asystole, premature atrial or ventricular contractions; followed by SNS discharge: tachycardia, hypertension, PVCs or VT, which peaks at 2mins.

132 (repeat) Aspirin Overdose. What will enhance her elimination most effectively?



A. Mannitol
B. Haemodialysis
C. lignocaine
D. ?
E. BIcarbonate infusion

133. A 50 year old male is having an aortic valve replacement for aortic stenosis. He is stable on bypass initially but after the first dose of cardioplegia his MAP falls to 25mmHg, CVP 1 and his mixed venous oxygen saturation is 80%. What is the best management in this situation?

A. Metaraminol bolus
B. Commence an adrenaline infusion
C. Increase oxygen flow rate
D. Increase pump flow rate
E. IV crystalloid bolus

Answer A



Cardioplegia induces transient hypotension secondary to K-related vasodilation, best managed with alpha blockade.



Millers 7th ed pg 1916 - "Initiation of CPB is often associated with a period of hypotension, which can be managed with the administration of an alpha-agonist into the venous reservoir of the ECC circuit. Any hypotension and hypertension that occur despite adequate flow and SvO2 can be treated by adjusting the patient’s SVR with vasoconstrictors or vasodilators”



Should be on full flows so D is incorrect

144. SG67 20 year old male 80kg presents post house fire with 30% burns. Using the Parkland formula how much fluid should he have replaced in the first 8 hours?

A. 2.6L N/saline
B. 3.6L N/saline
C. 3.6L CSL
D. 4.8L N/saline
E. 4.8L CSL

Answer E



BJA 2001 - A burn greater than 15% of the total body surface in adults and 10% in children requires intravenous fluid resuscitation. The Parkland formula, developed in 1971 and now widely used in the UK, predicts a total fluid requirement of 3-4 ml kg-1(% burn)-1. The resulting volume of fluid is given over the 24 h from the time of the burn (not from the time of presentation) with half the volume given in the first 8 h and the remaining half in the subsequent 16 h. Lactated Ringer’s solution is the fluid of choice.
Parkland formula = 4 x 30 x 80 = 9600mL = 4.8L in first 8hrs.



Some debate over whether to use 3 0r 4ml/kg (modified Parkland) however, question specifically asks for Parkland.

B



PS09 pp8: "Intravenous anaesthetic agents such as propofol must only be used by a second medical or dental practitioner trained in their use because of the risk of unintentional loss of consciousness. These agents must not be administered by the proceduralist." But also see Scenario 2 of Appendix 1 of PS09: the assistant can be shared between both ends for conscious sedation in ASA 1-2 patients only. Therefore best answer would be a medical or dental practitioner trained in its use with an assistant who may be shared with the proceduralist. --Farnsworth 06:17, 8 June 2014 (CDT)
