Perfusion index-derived parameters as predictors of hypotension after induction of general anaesthesia: a prospective cohort study.

ABSTRACT:

Background

Induction of general anaesthesia is commonly associated with hypotension. This exposes patients to perioperative organ hypoperfusion and eventually damage. This study was designed to assess the ability of preoperative perfusion index (PI), plethysmographic variability index (PVI), and dicrotic plethysmography (Dicpleth) to predict hypotension after induction of general anaesthesia.

Methods

In this cohort study, 95 ASA I and II adult patients who were scheduled for elective surgery under general anaesthesia were enrolled. The correlation between preoperative PI, PVI, Dicpleth and percentage decrease in mean arterial blood pressure after anaesthesia induction was investigated. Ability of PI, PVI, Dicpleth to detect post-induction hypotension was also analysed.
