Scientific titlePost-operative gum chewing and the return of bowel motility after elective caesarean section under regional anaesthesia: a prospective randomised controlled trial
Study objectivesIn a recent study, gum chewing - as a form of sham feeding - after caesarean section (CS) under general anaesthesia was found to be safe, well tolerated, and associated with rapid resumption of intestinal motility and shorter hospital stay. In developed countries, CS is mostly performed under regional anaesthesia, and the numbers of such cases are increasing in our country. So, the aim of the present study is to investigate the effect of gum chewing on the return of bowel motility after elective caesarean section under regional anaesthesia.
Ethics approval(s)Ethics & Research Committee of OB GYN Department, Faculty of Medicine, Ain Shams University, approved on the 22nd December 2009
Health condition(s) or problem(s) studiedBowel motility
InterventionFollowing CS, patients will be randomised to two groups:
Group 1: 24 patients will receive one stick of sugarless non-sweetened gum (Samarah Foods, Cairo, Egypt) for 15 minutes every two hours after surgery until the passage of flatus or bowel movement.
Group 2: 24 patients will receive traditional post-operative management, with oral intake of clear fluids and soft foods allowed after the passage of flatus and regular diet after bowel movement.

Total duration of treatment: about 24 hours (passage of flatus or motion) Total duration of follow-up: 1 week (first few days in hospital and by the end of first post-operative week in outpatient clinic)
Intervention typeOther
Primary outcome measure(s)With the time of end of surgery designated as zero hour, efficacy of gum chewing will be assessed based on shortened time interval to first hearing of normal intestinal sounds, to the first passage of flatus, to the first bowel movement, and to the discharge from the hospital.
Key secondary outcome measure(s)1. Recording of post-operative tolerance of gum chewing and post-operative complications, including febrile morbidity (temperature greater than 38ºC on two occasions 6 hours apart), re-operation, blood transfusion, post-operative ileus, and hospital readmission
2. Occurrence of mild ileus symptoms (vomiting or abdominal distension felt by the patient and seen on examination) or post-operative paralytic ileus, defined as a group of manifestations persisting longer than 24 hours or requiring nasogastric tube placement. These manifestations include absent or hypoactive bowel sounds, non-passage of flatus or bowel movement, abdominal distension, more than three episodes of vomiting, with or without generalised crampy abdominal pain.
