声门上喷射通气用于无痛肠镜检查的临床疗效

Clinical efficiency of application of supraglottic jet ventilation in painless colonoscopy

目的:探讨静脉麻醉下行肠镜检查的患者声门上喷射通气的有效性和安全性。方法:49例准备接受无痛肠镜检查的患者随机分为两组:对照组(n=24)采用常规鼻氧管被动供氧;声门上通气组(SJV组,n=25)采用手动喷射通气机主动供氧。丙泊酚静脉麻醉,持续监测心率(HR)、血压(BP)和血氧饱和度(SpO2)。结果:两组患者身高、体质量、年龄和体质指数(body mass index,BMI)差异无统计学意义。与对照组相比,SJV组SpO2平均最高值高于对照组(P=0.01),SJV组患者胸廓上抬程度3级,高于对照组(P=0.03)。两组间需要面罩通气次数、维持患者SpO2>96%患者的比例、平均呼气末二氧化碳(PetCO2)浓度及并发症发生情况差异无统计学意义。结论:声门上喷射通气能为行无痛肠镜检查的患者提供充足氧气,且不引起明显并发症。

Objective： To explore the efficacy and safety of supraglottic jet ventilation for patients undergoingcolonoscopy supported by monitored anesthesia care （MAC）. Methods.. Forty-nine patients scheduled for painless colonoscopy were randomly divided into two groups., the control group utilizing routine passive oxygen supply with nasal cannula （n= 24） and the supraglottic jet ventilation （SJV） group utilizing active oxygen supply with manual jet ventilator （n= 25）. Anesthesia was induced and maintained by intravenous injection of propofol. HR, BP, and SpO2 were continuously monitored. Results..There was no significant difference regarding height, weight, age, and body mass index （BMI） between the two groups. The averaged lowest and highest SpO2 in SJV group were significantly higher than those in the control group （P= 0. 01）. Degree of thoracic lifting movement in SJV group was significantly higher than that in control group （P〈0.03）. There was no significant difference regarding the times for using facial mask ventilation, the propotion of time for maintaining SpO2 above 96%, average PetCO2 during the procedure, or complications between the two groups. Conclusions.. SJV can provide adequate oxygen supply for patients undergoing painless eolonoseopy without obvious complications.
