Clinical Study On The Effect Of Feeding Time On Intestinal Function After Gastrointestinal Surgery

Purposes:The aim of this study was to detect the changes of intestinal sounds between early eating group and non-early eating group by continuous auscultation recorder,and to explore the recovery time,hospitalization cost and postoperative complications in the two groups.Differences in the recovery trend of intestinal sounds after operation.Methods:From September 2018 to February 2019,123 patients underwent gastrointestinal surgery in ShanXi Provincial people’s Hospital were examined by continuous auscultation recorder.The patients were divided into two groups according to whether they ate early after operation.There were 25 males and 14 females in the early feeding group and 45 males and39 females in the non-early eating group.Datas of patients included in research on bowel sounds,age,sex,body mass index(BMI),surgical site,exhaust time,hospitalization costs,postoperative complications and other basic information were collected.SAS 9.4(SAS Institute Inc.,Cary,NC,USA)was used to analyze the collected data of bowel sounds and clinical data.The counting data were expressed by frequency and percentage.The measurement data that conformed to the normal distribution were described by means of mean and standard deviation,and were analyzed by t test or analysis of variance.Statistical tests were performed.The chi-square test was used for the count data.Fisher’s exact test was used for the count data that did not satisfy the chi-square test.P<0.05 was considered statistically significant.Charts were made using GraphPad Prism 7.0 software.Results:The analysis of intestinal sounds in two groups of patients after gastrointestinal surgery showed that the frequency of intestinal sounds in the early eating group and the non-early eating group showed an increasing trend as a whole,and the intestinal function gradually recovered.But at the same time,the frequency of intestinal sounds in the early eating group was higher than that in the non-early eating group.There was a statistically significant difference in the first time of bowel sounds between the early eating group and the non-early eating group(24.04±13.09 h vs 32.69±16.97h,t=2.82,P=0.0057).There was a significant difference in the cost of hospitalization between the two groups(8.15±2.30 vs 10.84±2.64,t=6.51,P=0.001).There was significant difference in postoperative hospitalization days between early eating group(6.08±2.42)and non-early eating group(10.77±2.84),(t=0.89,P=0.001),and There was no statistical difference in the incidence of postoperative complications between the two groups(X~2=0.004,P=0.951).Conclusions:Early feeding after gastrointestinal surgery can promote intestinal peristalsis,accelerate recovery and reduce hospitalization costs.The trend of bowel sounds in early eating group and non-early eating group was analyzed by continuous auscultation recorder,which highlighted the advantages of early eating,and provided an assistant detection method for early eating after operation.
