The Optimal Time of Postoperative Feeding After Total Hip Arthroplasty: A Prospective, Randomized, Controlled Trial.

Whether early postoperative feeding (EPF) after total hip arthroplasty (THA) interferes with recovery of gastrointestinal motility is unclear. This randomized controlled trial compared the feasibility and patient tolerance to either EPF (at 4 hr postoperatively) or late postoperative feeding (LPF; ⩾8 hr postoperatively). One hundred forty patients were randomized to EPF (70 hips) or LPF (70 hips). Patient characteristics, surgical technique, intraoperative characteristics, and postoperative managements were similar between two groups. No significant differences were evident between the groups for vomiting (p = .231), nausea (p = .711), regain of appetite (p = .711), amount of diet (p = .630), type of food (p = .429), abdominal pain (p = 1.000), time to passage of flatus (p = .231), time to defecations (p = .619), development of postoperative ileus (p = 1.000), and length of hospital stay (p = .643). EPF and LPF show no difference in nausea, return of bowel function, and length of hospital stay without increasing postoperative morbidity. EPF can begin about 4 hr later after elective THA.
