洗胃过程中胃管置入长度的研究

The effects of different intubation's length of washing gastric tube

目的 探讨洗胃过程中胃管置入的最适长度 ,提高洗胃效果。方法 将 12 6例中、重度口服中毒患者随机分为 A、B、C三组。洗胃时 A组置入胃管长度为鼻尖 -耳垂 -剑突实测距离 (实测长度 ) ;B组置入实测距离再增加 5 cm ;C组置入实测距离增加 10 cm。结果 三组洗胃过程中均出入量平衡 ,而洗出血性液体者 A组占 2 .12 % ;B组占 19% ;C组占 30 %。三组间两两比较 ,P均 <0 .0 5。结论 经口置入洗胃管的长度以实测长度最合适。

Objective To investigate the most suitable intubation’s length of washing gastric tube during washing stomach.Methods 126 patients were divided randomly into three groups.The tube length in group A was the actual length from the nose to the earlap and plus to the xiphoid.The length in group B was the actual length in group plus 5cm,while group C plus 10cm.Results The in and out volume were balanced respectively among three groups.There were 2.12 percent,19percent,and 30percent bloody fluid washing from stomach in group A,B and C respectively.There was significant difference between group A,B and C.Conclusion The most suitable intubation’s length of washing gastric tube is the actual measuring length.
