Objective To explore the effect of disposable gastric cannula in gastric lavage of acute food poisoning patients. Methods One hundred cases of acute food poisoning patients admitted to a hospital in Zhengzhou from February 2017 to February 2019 were selected as the study subjects. The patients were divided into a control group and an observation group using a random number table

with 50 cases in each group. Patients in the con-trol group used traditional gastric tube; patients in the observation group used disposable sleeve gastric tube. The time taken to place the gastric tube

the success rate of first-time tube placement and the success rate of rescue were compared between the two groups; at the time of discharge from hospital

the complication rate was compared between the two groups; the patient satisfaction score was compared between the two groups. Results The difference in the time taken to insert the gastric tube between the two groups was not statistically significant（P>0.05）. The success rate of first-time tube placement and that of rescue in the observation group were 98.00% and 96.00%

respectively

which were higher than those of 86.00% and 80.00% in the control group

and the differences were statistically significant（P<0.05）. The complication rate of the patients in the observation group was 10.00%

which was lower than that of 30.00% in the control group

and the difference was statistically significant（P<0.05）. The service attitude

service content

personnel quality scores and total score of patients in the observation group were（4.52±1.27）

（4.38±1.25）

（4.46±1.21） and（13.66±4.13）

respectively

which were higher than the control group’s（2.35±0.22）

（2.26±0.15）

（2.31±0.48） and（7.63±2.32）

and the differences were statis-tically significant（P<0.05）. Conclusion The disposable gastric cannula used in the gastric lavage of acute food poisoning patients can improve the success rate of rescue and first-time placement

reduce the complication rate

and has favorable safety; it is beneficial to the clinical treatment of patients and thus worthy of clinical promotion and application.
