Feasibility of Stomach and Esophagus Guiding Tube using in Coma Patient with Pesticide Intoxication

Abstract

Objective To investigate the feasibility of stomach and esophagus guiding tube used in coma patients with pesticide intoxication.Methods 64 coma patients with pesticide intoxication were randomly divided into experiment group and control group averagely.Traditional gastric tube insertion were used in control group; and stomach and esophagus guiding tube was used in experiment group.Average insertion time,first insertion achievement ratio,blood pressure(SBP),and heart ratio (HR) during gastric tube insertion were observed.Rusults (1) Comparing with that before gastric tube insertion,SBP and HR at 2 min after gastric tube insertion in control group increased significantly (P＜0.05 or P＜0.01).Comparing with that in control group,the change range of HR at 2 min after gastric tube insertion in experiment group decreased markedly (P＜0.01).(2) Average insertion time were (86.8 ± 21.6)s and (31.2± 8.7)s in control group and experiment group,respectively; there was significant difference between both groups (t=3.28,P＜0.01).First insertion achievement cases were 32 and 20 in experiment group and control group,respectively; there was a significant difference between both groups (x2=14.77,P＜0.01).Conclusion Stomach and esophagus guiding tube can decrease average insertion time and stress reaction of gastric tube insertion and increase first insertion achievement ratio.
