Overview

Low-flow anaesthesia may cut volatile consumption with high acceptability; leaves open randomized confirmation before routine adoption.

Structured PICO

Does low-flow anaesthesia reduce volatile anaesthetic consumption and is it acceptable to anaesthetists in patients undergoing routine operative procedures?

P
Population
286 patients undergoing inhalational anaesthesia for routine operative procedures, and 28 anaesthetists at Northwick Park Hospital.
I
Intervention
Low-flow anaesthesia (fresh gas flow of 4 litres/minute or less)
C
Comparator
Conventional fresh gas flows
O
Outcome
Hourly consumption of volatile agents and anaesthetists' acceptance

Routine use of low-flow anaesthesia is acceptable to anaesthetists and significantly reduces volatile agent consumption, leading to potential financial savings.
