Does general anaesthesia reduce oxygen consumption?
General anaesthesia likely reduces oxygen consumption, but high-quality evidence in modern, high-risk surgical populations is lacking.
General anaesthesia probably reduces oxygen consumption but the effect estimate is uncertain. Given the limited generalizability and low quality of the available evidence, new studies in modern perioperative settings and in today's older high-risk surgical patient populations are needed.
Jakobsson et al. (Thu,) studied this question.
