摘要: 目的: 评估严格控制性降压(平均动脉压≤55 mmHg)对正颌手术术中出血量及术后肾功能的影响。方法: 选择2024年5月—2025年3月于上海交通大学医学院附属第九人民医院行正颌手术的患者117例,根据术中血压管理策略分为严格控制性降压组(S组,MAP≤55 mmHg)与常规管理组(C组,MAP>55 mmHg)。比较两组术中失血量、术后急性肾损伤发生率等主要指标,以及术后血红蛋白、红细胞压积、手术时长等次要指标。结果: S组术中失血量显著低于 C组(P<0.001),两组术后肌酐、Δ肌酐(术后与术前肌酐差值)及肌酐变异率无显著差异(P>0.05);S组术后血红蛋白、红细胞压积显著高于C组(P<0.05),降压时间显著长于C组(P<0.001);术中尿量、手术时间、异体输血率、术后不良事件发生率及住院时间两组无显著差异(P>0.05)。结论: 正颌手术中实施严格控制性降压(MAP≤55 mmHg)可有效减少术中失血,且不增加术后肾功能损伤及不良事件风险,安全性良好。

Abstract: PURPOSE: To evaluate the effect of strict controlled hypotension (mean arterial pressure≤55 mmHg) on intraoperative blood loss and postoperative renal function in orthognathic surgery. METHODS: A total of 117 patients who underwent orthognathic surgery in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from May 2024 to March 2025 were selected and divided into the strict controlled hypotension group (group S, MAP≤55 mmHg) and the conventional management group (group C, MAP>55 mmHg) according to the intraoperative blood pressure management strategy. The primary indicators such as intraoperative blood loss and postoperative incidence of acute kidney injury, as well as the secondary indicators such as postoperative hemoglobin, hematocrit and operation duration, were compared between the two groups. RESULTS: The intraoperative blood loss in group S was significantly lower than that in group C (P<0.001). There were no significant differences in postoperative creatinine, Δ creatinine (the difference between postoperative and preoperative creatinine) and creatinine variation rate between the two groups (P>0.05). The postoperative hemoglobin and hematocrit in group S were significantly higher than those in group C (P<0.05), and the hypotension duration in group S was significantly longer than that in group C (P<0.001). There were no significant differences in intraoperative urine output, operation time, allogeneic blood transfusion rate, postoperative adverse event rate and length of hospital stay between the two groups (P>0.05). CONCLUSIONS: The implementation of strict controlled hypotension (MAP≤55 mmHg) in orthognathic surgery can effectively reduce intraoperative blood loss without increasing the risk of postoperative renal function injury and adverse events, and has good safety.
