骶管阻滞复合全麻喉罩通气对小儿血液动力学的影响

目的 探讨骶管阻滞复合全麻喉罩通气对小儿血液动力学的影响.方法 择期下腹部、会阴部或下肢手术小儿60例,ASA I或II级.随机分为单纯气管插管组(T组),骶管阻滞复合气管插管组(CT组),骶管阻滞复合喉罩通气组(CL组),每组20例.分别于诱导前(T0)、插管即刻(T1)、手术开始(T2)、手术开始后30 min(T3)、手术开始后60 min(T4)监测心率(HR)、血压、脉搏氧饱和度、呼气末CO2分压,记录平均动脉压(MAP),中心静脉压,丙泊酚、瑞芬太尼的用量及术后不良反应的发生情况.结果 T组、CT组在T1时点MAP、HR明显高于CL组(P<0.05);CL组、CT组丙泊酚及瑞芬太尼的用量明显少于T组;CL组术后不良反应最少.结论 骶管阻滞复合全麻喉罩通气对小儿的血液动力学影响最小,不良反应少. Abstract： Objective To investigate the effects of caudal block with laryngeal mask airway(LMA) ventilation on the hemodynamics of children undergoing elective surgery under general anesthesia. Methods Sixty ASA Ⅰ or Ⅱ children undergoing selective lower abdominal surgery were randomly divided into 3 groups (n=20):Group T:endotracheal intubation. Group CT:caudal block and endotracheal intubatio. Group CL:caudal block and laryngeal mask airway(LMA) ventilation. HR,BP,MAP,CVP,SpO2,PetCO2 were monitored during anesthesia.HR,MAP,CVP were recorded at proinduction (T0),intubation(T1),operation(T2),30 min after operation(T3) and 60 min after operation (T4).Recording the dosage of propofol,remifentanil and adverse reactions of postoperation. Results MAP,HR at T1 were significantly higher in group T and group CT than that in group CL.The dosage of propofol and remifentanil were significantly less in group CT and group CL than that in group T. Conclusions Caudal block with LMA ventilation have little side effects on hemodynamics of the children undergoing slective surgery with general anesthesia.
