Objective To analyze the influencing factors of complete remission time of abdominal distension after painless colonoscopy in order to provide clinical guidance for nursing. Methods A total of 96 patients with abdominal distension after painless colonoscopy were selected from July to September 2019 in a hospital in Guangdong province. In this study

the average time of complete remission of abdominal distension was 4.51 h. 39 cases of patients with complete remission time of abdominal distension >4.51 h were included in the observation group

and 57 cases of patients with complete remission time of abdominal distension ≤4.51 h were included in the control group. The clinical data of all patients were collected

including gender

age

dietary taste

body mass index（BMI）

clinical manifestation

history of abdominal operation

intestinal preparation grade

Numerical Pain Rating Scale

Bruggrmann Comfort Scale and Gastrointestinal Symptom Rating Scale（GSRS）. The statistically significant factors in the results of univariate analysis were taken as independent variables and the time of complete remission of abdominal distension as dependent variables. Multivariate Logistic regression analysis was carried out to analyze the relevant risk factors affecting the time of complete remission of abdominal distension. Results There was no significant difference in gender

age

history of abdominal operation

intestinal preparation grade and Numerical Pain Rating Scale between the two groups（P>0.05）

but there were significant differences in dietary taste

BMI

times of bowel sounds per minute

Bruggrmann Comfort Scale and GSRS score between the two groups（P<0.05）. The results of multivariate Logistic regression analysis showed that the number of bowel sounds per minute（OR=0.176

P=0.038） was a protective factor for the time of complete remission of abdominal distension after painless colonoscopy. Bruggrmann Comfort Scale（OR=1.679

P=0.048） and GSRS score（OR=1.508

P=0.021） were risk factors for complete remission of abdominal distension after painless colonoscopy. Conclusion In clinical work

we should pay attention to the abdominal distension of patients after painless colonoscopy

especially the patients with lower intestinal sounds per minute

higher Bruggrmann Comfort Scale and GSRS score. We should strengthen management

shorten the time of complete remission of abdominal distension and improve the comfort after examination.
