[摘要]目的 探讨允许性高碳酸血症对丙泊酚复合舒芬太尼全凭静脉复合麻醉效果的影响。方法 选取2016年3月~2017年3月我院收治的90例择期拟行全身麻醉手术患者为研究对象,按入院时间顺序随机分为对照组和研究组,每组各45例。在麻醉期间,对照组控制动脉二氧化碳分压(PaCO2)在35~40 mmHg,研究组则控制PaCO2在50~65 mmHg。比较两组的丙泊酚应用情况(丙泊酚切皮时与腹腔探查效应部位浓度、术后苏醒时间)及术后1、2 h 的PaCO2水平。结果 ①研究组丙泊酚切皮时效应部位浓度为(2.511±0.206)mg/L,腹腔探查效应部位浓度(2.146±0.282)mg/L,均分别低于对照组(3.223±0.188)mg/L和(2.883±0.211)mg/L,差异有统计学意义(P<0.05)。对照组术后苏醒时间为(15.35±3.22) min,与研究组的(16.68±5.36) min比较,差异无统计学意义(P>0.05);②研究组术后1、2 h的PaCO2水平分别为(57.45±5.33)mmHg、(59.39±5.66)mmHg,均明显高于对照组的(35.24±4.32)mmHg、(37.56±5.68)mmHg,差异有统计学意义(P<0.05)。结论 全身麻醉手术患者采用允许性高碳酸血症是安全可行的。

[Abstract] Objective To investigate the effect of permissive hypercapnia on Propofol combined with Sufentanil combined intravenous anesthesia. Methods From March 2016 to March 2017, 90 cases of general anesthesia were selected in our hospital as study objects, and the patients were randomly divided into the control group (45 cases) and the study group (45 cases) according to the order of admission time. During the period of anesthesia, the arterial carbon dioxide partial pressure (PaCO2) of the control group was between 35~40 mmHg, while the study group was PaCO2 between 50~65 mmHg. The application of Propofol in two groups was compared (the concentration of Propofol and abdominal exploration and the time of postoperative recovery) and the PaCO2 level of 1, 2 h after operation. Results ①In the study group, the concentration of the effector domain was (2.511±0.206) mg/L at skin incision, and the concentration of the effector domain was (2.146±0.282) mg/L at intraperitoneal exploration, were lower than those of the study group (3.223±0.188) mg/L and (2.883±0.211) mg/L respectively, and the difference was statistically significant (P<0.05). The recovery time in control group was (15.35±3.22) min, which was not significantly different from that in the study group(16.68+5.36) min (P>0.05). ②The PaCO2 levels of 1, 2 h in the study group were (57.45±5.33) mmHg and (59.39±5.66) mmHg respectively, which were significantly higher than those in the control group(35.24±4.32) mmHg and(37.56±5.68) mmHg, and the difference was statistically significant (P<0.05). Conclusion It is safe and feasible to adopt permissive hypercapnia in patients undergoing general anesthesia.

有相關文献报道,若过于片面强调控制动脉二氧化碳分压(PaCO2)在正常范围内可能会对全身麻醉手术间伴有肺部疾病的患者造成严重的肺损伤[1]。允许性高碳酸血症是近年来被临床认识和证实的一种肺保护性通气策略,指在治疗呼吸系统疾病如呼吸窘迫综合征、慢性气道阻塞性疾病患者机械通气中允许CO2在一定范围内升高,以避免大潮气量或过高气道压等引起的相关性肺损伤[2-3]。学术界关于允许性高碳酸血症对在全身麻醉手术患者中应用丙泊酚复合舒芬太尼全凭静脉麻醉的影响报道较为少见[4]。本文通过选取90例全身麻醉手术患者作为研究对象,旨在探讨允许性高碳酸血症对丙泊酚复合舒芬太尼全凭静脉复合麻醉效果的影响。……
