I-gel喉罩对妇科腹腔镜手术患者呼吸功能的影响

Safety evaluation of I-gel laryngeal mask airway used in laparoscopic gynecological operation

目的比较I-gel喉罩与气管插管在妇科腹腔镜手术中对患者呼吸功能的影响。方法择期全麻下妇科腹腔镜手术患者80例,随机分为两组,在全麻诱导后分别采用喉罩(I)组和气管插管(T)组行机械通气,记录气腹前、后10 min、15 min呼气末CO_2(PETCO_2),气道平台压(Palat)、气道峰压(Ppeak)和肺顺应性(CL),并记录术后不良反应发生情况。结果气腹后10 min、15min,I组CL明显高于T组,Palat,Ppeak明显低于T组(P<0.05)。与气腹前比较,气腹后10 min、15 min,两组CL明显降低,PETCO_2,Pplat,Ppeak明显升高(P<0.01)。I组术后咽喉痛和呛咳的例数明显少于T组(P<0.05)。结论妇科腹腔镜手术中采用I-gel喉罩通气更安全,不良反应更少。

Objective To compare the influence on anesthesia and respiratory function in patients using I-gel laryngeal mask or tracheal intubation under general anesthesia in laparoscopicgynecological operation.Methods Eighty patients undergoing elective laparoscopic gynecological operation surgery were randomly divided to2groups(each40cases):laryngeal mask group(group I)and tracheal intubation group(group T).During surgery was maintained by intravenous medication and mechanical ventilation.PETCO2,Pplat,Ppeak,lung compliance(at3time points:before pneumoperitoneum,10minutes,15minutes after Pneumoperitoneum)and complications(sore throat,hoarse voice,bucking,nausea and vomitting)were re corded.Results Before pneumoperitoneum,there was no significant difference of airway resistance between group I and group T.After pneumoperitoneum,the decrease of airway resistance was observed in group S compared with group T(P<0.05).Less complications was observed in group S compared with group T(P<0.05).Conclusion Compared with tracheal intubation,I-gel laryngeal mask ventilation is safe and effective during laparoscopic gynecological operation.
