To reveal the risk factors of intraoperative hypotension (IH) and investigate whether IH was corrected in time.
This retrospective cohort study included patients undergoing surgeries in one medical centre. We divided all patients into two groups, the IH group and non-IH group. The clinical features of these two groups were compared and the independent risk factors for IH were analysed.
A total of 5864 non-cardiac surgery patients were included, of which 931 patients had IH diagnose. The independent risk factors of IH include older age, high grade American Society of Anaesthesiologists (ASA) physical status, intrathecal anaesthesia, emergency surgery and medical history of hypertension (P < .01). Among the patients with IH, 44.5% had hypotension lasting between 30 and 120 minutes, and 25.2% had hypotension lasting >120 minutes. Patients with IH are more likely to develop major post-operative complications after surgery (P < .01).
The independent risk factors of IH include older age, high grade ASA physical status, intrathecal anaesthesia, emergency surgery and history of hypertension. Hypotension during surgery is not always effectively treated.
揭示术中低血压（IH）的危险因素，并探讨 IH 是否及时得到纠正。
本回顾性队列研究纳入了在一家医疗中心接受手术的患者。我们将所有患者分为 IH 组和非 IH 组。比较两组患者的临床特征，并分析 IH 的独立危险因素。
共纳入 5864 例非心脏手术患者，其中 931 例诊断为 IH。IH 的独立危险因素包括年龄较大、较高的美国麻醉医师协会（ASA）身体状况分级、椎管内麻醉、急诊手术和高血压病史（P<.01）。在 IH 患者中，44.5%的患者低血压持续 30-120 分钟，25.2%的患者低血压持续>120 分钟。IH 患者术后发生主要术后并发症的风险更高（P<.01）。
IH 的独立危险因素包括年龄较大、较高的 ASA 身体状况分级、椎管内麻醉、急诊手术和高血压病史。手术期间低血压并不总是得到有效治疗。
