Q

Temperature measurement during cardiopulmonary bypass - which is most accurate:

A) Nasopharynx
B) Oxygenator arterial outlet
C) Oxygenator venous inflow
D) Bladder temp
E) PA Cath

A

Rewarming: nasopharyngeal done in practice for cerebral

Pulmonary artery > nasopharyngeal (~10-20cm in) > bladder»_space; tympanic
- in terms of accuracy

gold standard for continuous core temperature monitoring since this has been shown to be ‘closest to the temperature in the high internal jugular vein,’ which is the venous drainage of the brain. 2018 Indian resp journal

pulmonary artery ≥ nasopharynx > forehead > bladder > fingertip.
2007 Journal of Thoracic surgery: ranks reliability for DHCA

“Pulmonary artery (PA) or nasopharyngeal temperature recording is reasonable for weaning and immediate postbypass temperature measurement.” 2015 Society of Thoracic Surgeons doesn’t differentiate between the two

Q

Giving DDAVP to VWD type 3

a) No effect
b) If they’ve had a positive challenge test
c) Effective

A

No effect
- type 1: helps
- 2a maybe
- 2b contraindicated

Give TXA to each type - previous MCQ on what 1st thing to give is

In Type 3 vWD, where there is a severe deficiency or absence of vWF, desmopressin is not effective since there is insufficient vWF to release. These patients typically require factor concentrates (vWF-containing concentrates) for treatment instead of desmopressin.

Patient in VF during open aortic valve repair – what is the maximum safe energy for internal defibrillation? a. 20J b. 50J c. 100J
50J Internal defib requires less energy. Biphasic more effective than monophasic. For biphasic shocks, use 10- 20 J, delivered directly to the myocardium through internal paddles. Monophasic shocks require approximately double these energy levels. Do not exceed 50 J when using internal defibrillation - failure to defibrillate at these energy levels requires myocardial optimisation before defibrillation is attempted again https://lms.resus.org.uk/modules/m65-non-technical-skills/resources/chapter_9.pdf

What is the likelihood of a p value equal to or greater than 0.05 for a study repeated with exactly the same conditions and same sample size that produced a p value of 0.05? * 5% * 20% * 50% * 80% * 95%
50% Key Point from Goodman (1999): “If a study produces a p value of 0.05, and the same study is repeated under identical conditions, there is approximately a 50% chance the p value will exceed 0.05, due to sampling variability.” This is a well-accepted statistical principle that reflects the variability of p-values, especially when they are near the arbitrary threshold of significance (0.05). It highlights why replication is crucial in scientific research.

Ventilation strategy in an adult with Fontan circulation You are about to anaesthetise a 25 year old for an open appendicectomy. He has a history of tricuspid atresia for which he has had a fontan procedure. An important goal in managing his ventilation under anaesthesia is to ensure: a) ensure adequate PEEP B) decrease inspiratory time c) shorten IE ratio d) increase Inspiratory time e) ensure adequate spontaneous ventilation
b) Decreased inspiratory time Spont vent best (as ↑VR) PPV: Low inspiratory pressures/RR/times & low PEEP best

Anaesthesia-induced rhabdomyolysis How do you differentiate MH vs AIR a. myoglobinaemia b. hyperkalemia c. rigidity d. elevated etco2 e. hyperthermia
**Absence of muscle rigidity, note hyperkalaemia RARE** AIR presentation is of acute rhabdomyolysis --> ECG changes of ^K --> hyperK cardiac arrest - O2 sats remain normal until peri-arrest - ^EtCO2 is late sigh MH initially is a picture of muscle rigidity -> hypermetabolism --> deteriorates to uncontrolled rhabdomyolysis - O2 sats drop and ^ETCo2 early (due to hypermetabolic state) - Abnormal Ca2+ from SR -> sustained muscle contraction (distinguishing feature)
