Outcome measures
PIH, hypotension
SECONDARY
We defined hypotension as a minimum MAP below 60 mmHg or a decrease of more than 30% from baseline. These hypotension definitions have previously been associated with adverse postoperative outcomes, even transient intraoperative episodes [The main outcome of this study was the prevalence of “post-induction hypotension” (PIH, i.e., arterial hypotension occurring during the first 20 min after anesthesia induction or from anesthesia induction until the beginning of surgery.)The secondary outcomes were as follows: (1) The incidence of hypotension and minimum MAP during the maintenance of anesthesia and in the PACU. (2) MAP at baseline (TPatient demographic and clinical parameters were retrieved, including age, body mass index, fasting time, preoperative fluid volume, intraoperative fluid volume, American Society of Anesthesiologists physical status, education level, and anesthesia time. Anesthesia time was defined as the time from anesthesia administration to anesthesia withdrawal.
