环泊酚对左心室舒张功能不全老年患者麻醉诱导后血流动力学的影响

Effect of ciprofol on hemodynamics in elderly patients with left ventricular diastolic dysfunction after anesthesia induction

目的观察环泊酚对左心室舒张功能不全的老年患者麻醉诱导后至切皮前血流动力学的影响。方法选择择期全麻下行非心脏手术的老年患者82例,男42例,女40例,年龄65~90岁,BMI 18.5~30.0 kg/m^(2),ASAⅡ或Ⅲ级。采用随机数字表法将患者分为两组:环泊酚组(C组)和丙泊酚组(P组),每组41例。麻醉诱导:C组采用环泊酚0.3 mg/kg,P组采用丙泊酚1.5 mg/kg。记录麻醉诱导后至切皮前发生低血压的例数。记录麻醉诱导前(T_(0))、诱导后3 min(T_(1))、气管插管后即刻(T_(2))、插管后3 min(T_(3))、插管后5 min(T_(4))和插管后10 min(T_(5))时的HR、SBP、DBP和心脏指数(CI)。记录麻醉诱导后至切皮前血管活性药物使用例数,注射痛、呛咳、术中体动和心动过缓的发生例数。记录苏醒期躁动和术后48 h内恶心呕吐等不良反应的例数。结果与P组比较,C组麻醉诱导后至切皮前低血压发生率明显降低(P<0.05)。与T_(0)时比较,T_(1)-T_(5)时两组HR明显减慢(P<0.05),SBP、DBP和CI明显降低(P<0.05)。与P组比较,T_(5)时C组CI明显升高(P<0.05),注射痛发生率明显降低(P<0.05)。两组不同时点HR、SBP和DBP差异无统计学意义。两组麻黄碱、去氧肾上腺素和阿托品使用率,呛咳、术中体动、心动过缓、苏醒期躁动和术后48 h内恶心呕吐发生率差异无统计学意义。结论环泊酚对左心室舒张功能不全的老年患者血流动力学影响更小,可安全用于老年患者非心脏手术的麻醉诱导。

Objective To observe the effect of ciprofol on hemodynamics in elderly patients with left ventricular diastolic dysfunctionfrom induction of anesthesia to incision.Methods Eighty-two elderly patients,42 males and 40 females,aged 65-90 years,BMI 18.5-30.0 kg/m^(2),ASA physical statusⅡorⅢ,undergoing non-cardiac surgery under elective general anesthesia were enrolled.The patients were randomly divided into two groups:ciprofol group(group C)and propofol group(group P),41 patients in each group.Anesthesia induction was performed using ciprofol at a dose of 0.3 mg/kg in group C or propofol at a dose of 1.5 mg/kg in group P.The number of patients with hypotension between anesthesia induction and skin incision were recorded.HR,SBP,DBP,and cardiac index(CI)were recorded immediately before anesthesia induction(T_(0)),3 minutes after induction(T_(1)),immediately after tracheal intubation(T_(2)),3 minutes after tracheal intubation(T_(3)),5 minutes after tracheal intubation(T_(4)),and 10 minutes after tracheal intubation(T_(5)).Intraoperative use of vasoactive drugs,the incidence of injection pain,bucking,movement and bradycardia from induction of anesthesia to incision were recorded.The occurrence of adverse reactions such as postoperative agitation,nausea and vomiting within 48 hours after surgery were also recorded.Results Compared with group P,the incidence of hypotension in group C from induction of anesthesia to incision was significantly decreased(P<0.05).Compared with T_(0),HR at T_(1)-T_(5) in the two groups slowed down significantly(P<0.05),and SBP,DBP,and CI were significantly decreased(P<0.05).Compared with group P,CI in group C was significantly higher at T_(5)(P<0.05),and the incidence of injection pain was significantly decreased(P<0.05).There was no significant difference in HR,SBP and DBP between two groups at different time points.There was no significant differences in the rates of ephedrine,phenylephrine and atropine,bucking,intraoperative movement,bradycardia,postoperative agitation and nausea and vomiting within 48 hours after surgery between the two groups.Conclusion Ciprofol has a smaller impact on the hemodynamics of elderly patients with left ventricular diastolic dysfunction and can be safely used for anesthesia induction in elderly patients undergoing non-cardiac surgery.
