Evaluation Of Intestinal Function After Gastrointestinal Surgery By Digital Intestinal Sound Monitoring System

Objective:The digitized intestinal sound monitoring system was used to continuously monitor the intestinal sounds of patients after gastrointestinal surgery.The regularity and influencing factors of the intestinal sounds were analyzed.The intestinal function after operation was more scientifically understood and clinical practice was guided.Method:From September 2018 to February 2019,123 patients who underwent gastrointestinal surgery in General Surgery Dept.2 of Shaanxi provincial people's hospital were monitored continuously.Sex,age,body mass index,surgical site,operation time,anesthesia time,exhaust time,fasting time,hospitalization days were collected,and the correlation between them and the characteristic parameters of bowel sounds was analyzed.SAS 9.4 was used for data analysis,t-test was used for single factor analysis and Pearson correlation analysis was used for bivariate data.All data were considered to have statistical significance with P < 0.05.Graph Pad Prism 7.0 software was used to make statistical maps.Result:The amplitude,main frequency,duration and interval of bowel sounds remained almost unchanged in 123 patients after operation,but there was no significant change with the time of operation.Postoperative intestinal rate showed an overall upward trend.Sex,age,body mass index and surgical site were not the factors influencing the recovery time of bowel sounds.The length of operation,anesthesia and recovery time of bowel sounds were wireless,while the length of exhaust time(P = 0.0007),fasting time(P = 0.0139),hospitalization days(P < 0.0001)were positively correlated with recovery time of bowel sounds.Conclusion:1.The digital intestinal sounds monitoring system was used to preliminarily realize the accurate acquisition,objective recording and automatic analysis of intestinal sounds in this study,which can quantitatively reflect the intestinal motility.2.The average intestinal rate of patients after gastrointestinal surgery showed an upward trend,which more objectively and quantitatively indicated the gradual recovery of intestinal function.3.Gender,age,body mass index,surgical site,length of operation and duration of anesthesia were not the relevant factors affecting the recovery of bowel sounds after operation.4.The recovery time of bowel sounds was positively correlated with the time of exhaust,feeding and hospitalization after operation.The recovery time of bowel sounds was much earlier than the time of anal exhaust.Taking exhaust as the index of eating would delay the patients' feeding time and prolonged the days of hospitalization.
