Body mass index and risk of post-induction hypotension in older adults undergoing non-cardiac surgery: a retrospective cohort study.

ABSTRACT:

Background

Post-induction hypotension (PIH) is a frequent complication among older adults undergoing general anaesthesia, associated with organ hypoperfusion and increased perioperative risk. The role of body mass index (BMI), a routinely assessed and potentially modifiable risk factor, in the development of PIH remains unclear in geriatric populations.

Methods

We conducted a retrospective cohort study of patients aged ≥ 60 years who underwent elective non-cardiac surgery under general anaesthesia between 2013 and 2022 at a tertiary hospital. Preoperative BMI was analysed both as a continuous and categorical variable. The primary outcome was PIH, defined as a systolic blood pressure < 90 mmHg or > 30% reduction from baseline during the post-induction period. Secondary outcom
