Study information
Scientific title
POMX (Post Operative Morbidity): randomized controlled trial of chewing gum to reduce postoperative morbidity in elective orthopaedic surgery
Acronym
POM-X
Study hypothesis
Complications following surgery are an important cause of morbidity (illness) and mortality (death). When these complications occur within 30 days of major surgery, long term survival is reduced.
The return of gut movement after elective surgery is important to prevent nausea, vomiting, and abdominal discomfort. Under some circumstances this gut movement is reduced which can lead to delays in oral intake and delayed discharge from hospital. Gastrointestinal dysfunction after surgery is associated with morbidity in other body systems. Chewing-gum is considered a form of 'sham feed' e.g. an imitation of food ingestion. 'Sham-feeding' can help facilitate gut motility by the activation of gastrointestinal hormones.
The POM-X trial is designed to examine if the act of chewing gum following orthopaedic surgery can reduce the incidence of complications postoperatively.
Understanding this mechanism may help us to understand why some patients sustain complications after surgery.
This will allow future clinical care to be guided by an understanding of why these complications arise and allow early detection, treatment and avoidance of postoperative morbidity.
