Preoperative malnutrition is a risk factor for intraoperative hypotension in high-risk surgical patients: a propensity score-matched cohort study.

ABSTRACT:

Background

Intraoperative hypotension (IOH) is associated with adverse outcomes in high-risk surgical patients. Preoperative malnutrition may increase susceptibility to IOH, but evidence regarding its association with IOH assessed through multiple dimensions remains limited. This study aimed to evaluate the association between malnutrition and IOH.

Methods

This retrospective cohort study included 1504 adult patients who underwent elective high-risk non-cardiac surgery under general anesthesia. Nutritional status was assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria. IOH was evaluated across four dimensions: incidence, cumulative duration, proportion of anesthesia time in IOH, and lowest mean arterial pressure (MAP), based on both absolute (MAP <
