Anaesthesia · Complications: awareness
Sample itemWhich surgery carries the highest risk of intraoperative awareness?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Cardiac surgery, caesarean section under general anaesthesia and trauma
Awareness is more likely when anaesthetic depth is deliberately light because of haemodynamic instability, such as in trauma, caesarean section and cardiac surgery, or when muscle relaxants mask movement. Use of BIS or end-tidal agent monitoring helps.
Option by option
A. Appendicectomy in adults
Routine cases carry a low risk.
B. Knee arthroscopy under spinal
Spinal anaesthesia is without general anaesthesia.
C. Cataract surgery
Cataract surgery usually uses topical or local anaesthesia.
D. Cardiac surgery, caesarean section under general anaesthesia and trauma (correct)
Correct. Light anaesthesia is used in these cases.
