ABSTRACT
Objective:
To evaluate the effect of individualized blood pressure management on postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.Methods:
One hundred and sixty elderly hypertensive patients of both sexes, aged 60-80 yr, with body mass index of 19-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection for gastrointestinal tumor under general anesthesia, were divided into 2 groups ( n=80 each) using a random number tablemethod:
standardized blood pressure management group (group S) and individualized blood pressure management group (group I). Combined intravenous-inhalational anesthesia was performed, and BIS values were maintained at 40-60 and heart rate at 50-100 times/min during surgery in both groups. In group S, intraoperative systolic blood pressure was maintained above 90 mmHg with a decrease of less than 30% of the baseline value, while intraoperative fluctuation of systolic blood pressure was maintained less than 10% of the baseline value in group I. The use of vasoactive agents, numerical rating scale scores within 3 days after operation, and length of hospital stay were recorded. Postoperative delirium was evaluated by Confusion Assessment Method within 5 days after surgery.Results:
Compared with group S, the intraoperative usage rate of norepinephrine was significantly increased, the incidence of postoperative delirium was reduced( P<0.05), and no significant change was found in the numerical rating scale scores and length of hospital stay in group I ( P>0.05).Conclusions:
Individualized blood pressure management can reduce the development of postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.
