气囊式胃管的研制及临床应用

Development and Clinical Application of Air-sack Stomach-tube

目的研制出的气囊式胃管替代普通胃管,减少普通胃管易滑脱而反复插管而引起的胃粘膜出血、喉头水肿、咽炎、食管炎等副损伤。方法气囊式胃管为双腔道结构,气囊装置有独立腔道,位于胃管头端5cm处。将140例留置胃管病人随机分成2组,观察组应用气囊式胃管,对照组应用普通胃管,观察2组病人胃粘膜出血率、胃管滑脱率、喉头水肿率。结果观察组病人胃粘膜出血率、胃管滑脱率、喉头水肿率明显降低,与对照组相比有显著差异(P<0.01)。结论气囊式胃管留置副损伤发生率明显低于普通胃管,有临床推广价值。

Objective To develop air-sack stomach-tube to replace traditional stomach--tube and reduce complications such as gastric mucosal bleeding, larynx edema, pharyngitis, esophagitis that are caused by repeated slip of traditional stomach--tube. Methods The air--sack stomach--tube was designed as double--space air--sack, which has independence tract and it was located at 5 cm from the head of stomach--tube. 140 patients who received gastric tube indwelling were divided into two groups randomly. Patients in observation group （n= 70） used air--sack stomach--tube in gastric tube indwelling and those in control group（n= 70 ） used traditional stomach--tube. Incidence of gastric mucosal bleeding, gastric tube slipping and larynx edema were observed and compared. Results In observation group, incidence of gastric mucosal bleeding, gastric tube sliping and larynx edema were greatly reduced than that of control group, and the differences were significant （P 〈 0.01）. Conclusions Complications of air--sack stomach--tube indwelling are less than that of traditional stomach--tube, so it is suitable for clinical nursing.
