Develepment and application of the inserted mouth gag

Abstract

Objective To evaluate the effectiveness of mouth gag which can inserted into lavage tube during gastric lavage. Methods The Sixty-six cases of acute poisoning patients with gastric lavage according to random number table method were randomly divided into two groups, 33 cases in each group. Observation group used the inserted mouth gag, and the control group used the metal ones. Results The observation group were lower than the control group at the time required to insert the lavage tube [(2.23±0.19) s to (3.26±0.30) s] and the incidence of complication rate [18.2%(6/33)to 45.5%(15/33)], the oral cavity bleeding [6.0%(2/33) to 30.3%(10/33)], lavage tube displacement [0 (0/33)to 24.2%(8/33)], lavage tube twisting[0(0/33) to 24.2%(8/33)], the difference was statistically significant (P<0.01), while higher in the rate of successful intubation[100.0%(33/33)] to [54.5%(18/33)], the difference was statistically significant, χ2= 19.4, P<0.01. Conclusions The application of the mouth gag which can insert into gastric lavage improved the successful intubation rate, saved the rescue time, reduced the complication and improved the nursing quality.
