Three randomized controlled trials involving 268 patients with adolescent idiopathic scoliosis were included in this systematic review and meta-analysis comparing the use of chewing gum versus standard care for managing postoperative abdominal pain and nausea. Pooled outcomes of interest included postoperative abdominal pain scores, postoperative nausea scores, and hospital stays. The pooled results indicated no significant effect of chewing gum on reducing postoperative abdominal pain or nausea at 24 and 48 hours, or on the duration of hospital stay. This systematic review and meta-analysis concluded that chewing gum does not significantly impact postoperative outcomes in this patient population, suggesting that its role in spinal surgery requires further investigation with larger sample sizes.
