Effects of menthol gum chewing on postoperative nausea, vomiting, and length of hospital stay in children undergoing appendectomy: A randomized controlled trıal

This study aimed to determine the effects of menthol gum chewing on nausea, vomiting, and length of hospital stay after appendectomy in children.Postoperative nausea and vomiting (PONV) can be induced by general anesthesia. Several drugs are available to reduce the risk of PONV; however, their cost and side effects limit their clinical use.This was a randomized controlled clinical trial that included 60 children aged 7-18 years who underwent an appendectomy at the Pediatric Surgery Clinic of a tertiary hospital between April and June 2022. Data for this study were collected via the developed information form, which included participants' descriptive characteristics and bowel function parameters, and the Baxter Retching Faces (BARF) nausea scale. Children in the study group who underwent an appendectomy were given chewing gum and asked to chew it for an average of 15 min, whereas those in the control group received no intervention.The BARF nausea score measured during the menthol gum chewing period was lower in the study group, and the difference score value calculated after pretest time was higher in the study group, as expected (p < 0.001). Moreover, menthol gum chewing was found to shorten hospital stay by 1 day (p < 0.05).Menthol gum chewing reduced the severity of postoperative nausea and length of hospital stay.Chewing gum can be used as a nonpharmacological method by pediatric nurses in clinical practice to reduce the severity of postoperative nausea and length of hospital stay.
