多孔胃管并延长插入长度在口服有机磷农药中毒洗胃中的临床研究

Clinical Study on the Application of Porous Stomach-tube and Extension of Insertion Length in Gastric Lavage for Patients of Oral Intoxications of Organophosphorous Pesticide

目的 在传统插管长度的基础上再延长插入 1 0～ 1 5cm的临床研究来实现最佳洗胃效果。方法 将 1 4 0例口服中毒患者随机分为 2组 :观察组 (A组 ) 71例和对照组 (B组 ) 6 9例。B组采用传统洗胃方法和插入长度 ;A组采用多孔胃管并延长插入长度 1 0～ 1 5cm。结果 总洗胃时间 :A组比B组缩短了 1 1min(P <0 .0 1 ) ;不良反应、并发症及胃内残留液发生率 :A组占 1 4 .0 8%,B组占 5 6 .5 2 %(P <0 .0 1 )。结论 采用多孔胃管并延长插入长度的方法 ,达到洗胃速度快、洗胃液引流通畅 ,对胃黏膜刺激、损伤小 ,不良反应轻 ,并发症少。

Objective Clinical study on extending insertion length by 10～15 cm, with length of cannula remaining the same, is made in order to achieve the best effect of gastric lavage. Method 140 patients of oral intoxications are randomly divided into two groups: 71 in observation group (group A) and 69 in comparison group (group B). Group B is treated by traditional method of gastric lavage with no change in insertion length, while group A is treated by porous stomach-tube with the insertion length of cannula being extended by 10～15 cm. Results The overall time in gastric lavage of group A is shorter than that of group B by 11 minutes(P<0.01). As to the incidence of adverse reaction, complications and residual gastric fluid, group A is 14.08% and group B is 56.52%(P<0.01). Conclusion The application of porous stomach-tube and extension of insertion length have many benefits: quicker speed of gastric lavage, smoother drainage of lavage fluid, smaller irritation and injury to gastric mucosa, less adverse reaction and complications.=
