Anaesthesia · Preoperative assessment: respiratory infection in a child
Sample itemA 4-year-old has had a runny nose, cough and low-grade fever for two days and is listed for elective squint surgery. Which anaesthetic complications are more likely?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Laryngospasm, bronchospasm and desaturation from airway hyperreactivity
A recent upper respiratory infection makes the airway hyperreactive for several weeks, increasing perioperative respiratory adverse events such as laryngospasm, bronchospasm, breath holding and desaturation. The decision to proceed depends on severity, the airway to be used and the urgency of surgery.
Option by option
A. Laryngospasm, bronchospasm and desaturation from airway hyperreactivity (correct)
Correct. Airway hyperreactivity after a respiratory infection increases laryngospasm and bronchospasm.
B. Delayed emergence from slowed elimination of volatile agents
A cold does not slow the elimination of volatile agents.
C. Malignant hyperthermia and masseter spasm
Malignant hyperthermia is a genetic disorder, not a consequence of an infection.
D. Anaphylaxis to induction agents
Infection does not increase the likelihood of anaphylaxis to induction agents.
