Effectiveness of Chewing Gum on Nausea and Vomiting Following Postprocedure: A Systematic Review and Meta-Analysis.
Journal of Perianesthesia Nursing : Official Journal of the American Society of PeriAnesthesia Nurses 2024 January 10
PURPOSE: This study aimed to evaluate the effectiveness of chewing gum in reducing postprocedure nausea and vomiting.
DESIGN: A systematic review and meta-analysis.
METHODS: A systematic literature search was performed on MEDLINE Complete, EMBASE, CINAHL, PubMed, Web of Science, Academic Search Complete, and Cochrane Library databases from their inception to October 2, 2022. Methodological quality was assessed using the revised Cochrane Risk of Bias 2.0 tool for randomized trials. A meta-analysis was performed using a fixed-effects model to calculate pooled effects with Review Manager 5.4.1.
FINDINGS: Twelve randomized trials encompassing 1,458 participants were pooled. The chewing gum intervention was effective in reducing vomiting (P = .007; risk ratio = 0.55; 95% Cl = 0.35-0.85), but not nausea (P = .14; risk ratio = 0.84; 95% Cl = 0.66-1.06). Thirty-minute sessions of gum chewing were significantly more effective in reducing vomiting than 15-minute sessions (P = .04; risk ratio = 0.31; 95% Cl = 0.1-0.93).
CONCLUSIONS: The results indicate that repeated gum chewing sessions of at least 30 minutes may act as a nonpharmacological intervention for reducing vomiting. However, further studies are necessary to determine the outcomes of chewing gum interventions.
