Finals Black Bank

Hey Guys,

Question for those sitting the March 2013 exam. In chatting with some of the physicians they manage to get a complete multi-choice paper for their colleagues coming through by instead of everyone randomly sending in the answers they are assigned 1 or 2 questions which they remember word perfect, jot down immediately and then send to someone to collaborate. Even if only 75 people are interested, we would only have to remember 2 questions each and we could post a complete exam for once. Yes I know I don't plan on sitting the exam again either but I certainly have a number of friends who would be most appreciative. I have created an e-mail page and am happy to collate if there is enough interest. Just send me your name and an e-mail to the following address and if we get enough people I will send you your questions the week or so before the exam.

Rpt: Best renal protection for endoluminal AAA repair?

A. NaCl
  • Answer A. The benefit of isotonic i.v. fluid expansion for the prevention of radiocontrast-induced nephropathy has been clearly demonstrated.

Disappointingly, recent trials in the perioperative and ICU settings have shown a LACK of renal protective benefit of NAC. These trials have been performed in high-risk patients undergoing cardiac surgery, open abdominal aortic aneurysm repair,and abdominal aortic EVAR. CEACCP

Rpt: Desflurane vaporiser heated because:

A. High SVP
B. High boiling point
C. Low SVP
D. High MAC
E. Low MAC
  • Answer A
  • High SVP 
672 mmHg at 20C
Heated to 39C, SVP of 1550 mmHg. This means that desflurane is nearly boiling at room temperature. If administered in a conventional plenum-vaporiser could produce disastrous changes in output with small increases in temperature. If the vaporiser temperature rose above the boiling point a continuous flow of gaseous agent would be produced until all the liquid evaporated, or until the latent heat of vaporisation resulted in the temperature being lowered below the boiling point. The Tec6 overcomes this using a vaporiser with a sump heater so that vapour pressure is raised to around two atmospheres absolute pressure (37C) internally and then dispensed using a system of differential pressure transducers and variable resistance. The vapour can be mixed with fresh gas using a metering valve. The entire vapour pathway is heated to prevent the high partial pressure of the agent (potentially above the saturated vapour pressure at room temperature) from "raining out".
  • Properties: BP 23.5C; Blood:gas coefficient 0.42; Oil gas coefficient 19; MAC 6%;
  • SVP = pressure exerted by the molecules in a vapour at the point of equilibrium with its liquid phase. Dependent on agent and temperature. (mmHg)

• Other agents SVP at 20C: Sevo 157mmHg; isoflurane 238mmHg; enflurane 172mmHg; nitrous oxide 39,000mmHg

Rpt: CTG [pictured] demonstrating late decelerations. Most likely cause?

A. Fetal asphyxia
B. Head compression
C. Cord compression
D. Uteroplacental insufficiency
  • Ans A.
  • Early decelerations appear to be caused by vagal discharge produced when the head is compressed by uterine contractions. The onset and depth of early decelerations mirror the shape of the contraction, and tend to be proportional to the strength of the contraction.
  • Late decelerations occur when a fall in the level of oxygen in the fetal blood triggers chemoreceptors in the fetus to cause reflex constriction of blood vessels in non-vital peripheral areas in order to divert more blood flow to vital organs such as the adrenal glands, heart, and brain. Constriction of peripheral blood vessels causes hypertension that stimulates a baroreceptor mediated vagal response which slows the heart rate. The time consumed in this two-step process accounts for the delay in the timing of the deceleration relative to the contraction

A. Predict intraop anaesthetic risk
B. Predict intraop surgical and anaesthetic risk
C. Standardize description of physical status

Rpt: Best agent to decrease both gastric volume and gastric acidity?

A. Omeprazole
B. Ranitidine
C. Metoclopramide

PPI (such as omeprazole) increase gastric pH and reduce gastric volume but required to be given 12hrs in advance. Sodium citrate increase pH & increases gastric volume. H2 receptor antagonists reduce gastric volume and increase pH if given 1-2hrs in advance. (Remember "acidity" decreases as pH increases).

Rpt: Cholecystectomy.

A. Most likely to get gas embolism at initial CO2 insufflation

Rpt: Diastolic dysfunction is NOT caused by?

A. Adrenaline
B. Constrictive pericarditis
  • Answer A.
Any condition or process that leads to stiffening of the left ventricle can lead to diastolic dysfunction. Causes of left ventricular stiffening include:
-A long standing hypertension, where - as a result of left ventricular muscle hypertrophy to deal with the high pressure - the left ventricle has become, stiff)
-Aortic stenosis of any cause: the ventricular muscle becomes hypertrophied and thence stiff as a result of the increased pressure load placed on it by the stenosis)
-Age - elderly patients mainly if they have hypertension.
  • Causes of isolated right ventricular diastolic failure are uncommon. These causes include:
- Constrictive pericarditis
- Restrictive cardiomyopathy, which includes Amyloidosis (most common restrictive), Sarcoidosis and fibrosis.
- Adrenaline increases systolic blood pressure (beta-1 action) with slight decrease in diastolic blood pressure (beta2 -> vasodilation).

Rpt: Amniotic fluid embolism. Early cause of death?

A. Pulmonary HTN
B. Malignant arrhythmia
C. Pulmonary oedema
D. Hypovolaemic shock
  • Answer A
  • Phase 1: Amniotic fluid and fetal cells enter the maternal circulation resulting in the release of biochemical mediators which cause pulmonary artery vasospasm followed by pulmonary hypertension. This results in elevated right ventricular pressures and right ventricular dysfunction, which will lead to hypoxaemia and hypotension with associated myocardial and capillary damage. Phase 1 may last up to 30 min.
  • Phase 2: This occurs in patients who survive the initial insult. Left ventricular failure and pulmonary oedema occur. Biochemical mediators trigger DIC leading to massive haemorrhage and uterine atony.
