The Effect of Menthol Ice on Laparoscopic Cholecystectomy Patients' Thirst, Dry Mouth, Mouth Taste, and Bad Mouth Odor: A Randomized Controlled Trial.

PURPOSE: This study aimed to determine the effect of menthol ice application on thirst, dry mouth, mouth taste, and bad mouth odor in patients who underwent laparoscopic cholecystectomy in the postoperative period. DESIGN: The study was conducted as a randomized controlled trial with an experimental design. METHODS: The study sample consisted of 90 patients who underwent laparoscopic cholecystectomy and met the inclusion criteria. Patients were divided into three groups by randomization program. Patients in the menthol ice and ice popsicle (ice prepared with drinking water only) group were administered menthol ice/ice popsicle (10 mL) twice at 20 minutes intervals. Patients in the control group did not receive any intervention. Routine practices of the clinic were performed by the nurses of the general surgery clinic. Postoperative thirst intensity, severity of dry mouth, bad taste, and bad odor in the mouth were evaluated at 0, 20, and 40 minutes. FINDINGS: No statistically significant difference was found between the sociodemographic and clinical characteristics of the patients in the control group, menthol ice group, and ice popsicle group (P > .05). A statistically significant difference was found between the 3 groups in terms of thirst intensity and severity of dry mouth at times at the 20th and 40th minutes after the application (P < .01). We found a statistically significant difference between the bad taste and bad odor sensation scores of the patients in the control and intervention groups at the 20th and 40th minutes after the application (P < .05). CONCLUSIONS: The study concluded that menthol ice and ice popsicle application are effective strategies to reduce the intensity of thirst, severity of dry mouth, bad taste, and bad odor in postoperative patients.
