It is reported that hypotension during general anesthesia is associated with adverse outcomes in patients having both noncardiac and cardiac surgery. The present retrospective study was undertaken to evaluate the incidence and the predictors of hypotension after induction of general anesthesia (GA) until the start of operation.
After the IRB approval, 157 patients with hypertension who had undergone surgery under general anesthesia were enrolled. Data were collected using medical chart and anesthesia record. We divided the period into two intervals, from entering the operating room to tracheal intubation (first interval) and from tracheal intubation to start of operation (second period). Hypotension was defined when blood pressure decreased more than or equal to 25 percent compared to blood pressure measured at first in operating room.
Hypotension occurred in 73.2% during the first interval and 96.8% during the second interval. The age was a significant predictor for hypotension during the second interval (P = 0.0087).
The result in this study indicated that the age was a significant predictor for hypotension from tracheal intubation to start of operation.
据报道，全身麻醉期间的低血压与非心脏手术和心脏手术患者的不良结局相关。本回顾性研究旨在评估全身麻醉诱导后至手术开始时低血压的发生率及预测因素。
经机构审查委员会批准后，纳入157例接受全身麻醉手术的高血压患者。通过病历和麻醉记录收集数据。我们将该时间段分为两个区间，从进入手术室至气管插管（第一个区间）以及从气管插管至手术开始（第二个区间）。当血压较在手术室首次测量的血压下降大于或等于25%时定义为低血压。
第一个区间低血压发生率为73.2%，第二个区间为96.8%。年龄是第二个区间低血压的显著预测因素（P = 0.0087）。
本研究结果表明，年龄是气管插管至手术开始时低血压的显著预测因素。
