ManujetⅢ手控喷射通气(MJV)用于患儿长时留存气道异物取出术的效果

The efficacy of manual jet ventilation(MJV) using Manujet Ⅲ in removal of long retain airway foreign body in children

目的评价ManujetⅢ手控喷射通气(manual jet ventilation,MJV)用于气道异物长时间留存的患儿异物取出术的效果。方法回顾性研究我院自2004年6月至2008年9月气道异物超过30天的患儿,根据术中通气方式分为ManujetⅢ手控喷射通气组(m组)和借硬直喉镜侧孔通气组(n组)进行对照分析。结果术前两组患儿一般情况无明显差异,m组术中低氧发生率低于n组(P=0.03 5,χ2=4.43 1);手术时间(P=0.03 1,t=5.01 6)和苏醒时间(P=0.04 3,t=3.42 6)短于n组。结论 ManujetⅢ手控喷射通气可降低患儿长时间留存的气道异物取出术术中的缺氧发生率、缩短手术及苏醒时间。

Objective To explore the clinical efficacy of Manujet III manual jet ventilation （MJV） in removal of long retain airway foreign body （FB）. Methods We reviewed the records of all the children who underwent the removal of airway FBs using rigid bronchoscopy between Jun. 2004 and Sep. 2008. The patients whose time of FBs aspiration exceed 30 days were admitted into our study. The efficacy of ventilation by Manujet Ⅲ （Group m,n= 40） and by rigid bronchoscopy （Group n,n= 27） was analyzed. Results There was no significant difference between Group m and Group n on the distribution of patients and complications before operation. The incidence of hypoxemia during operation was lower, and the duration of operation and emergence from anesthesia were shorter in Group m than in Group n （P^0.05）. Conclusions MJV with Manujet Ⅲ in FB removal can offer sufficient ventilation and shorten operation time as well as fasten analepsia.
