Clinical Trial Summary

The study was planned as a randomized controlled experimental study to determine the effect of inhalation use of ginger and peppermint on postoperative nausea and vomiting in patients undergoing thyroidectomy surgery. After the approval of the ethics committee and institutional permission, 81 patients who applied to the general surgery clinic for thyroidectomy between 1 December 2020 and 1 December 2021 and met the inclusion criteria will be included in the study. Within the scope of the planned study, the sample size in the light of the reported academic studies was determined as effect size d = 0.40 (effect size), α = 0.05 (margin of error), 1-β = 0.90 (Power) and by using the G-power package program with the specified criteria. It was decided to recruit 81 people (27 people per 3 group). Block randomization method will be used to determine the experimental and control groups. In order for the groups to be distributed homogeneously, the order produced by a computer program (https://www.randomizer.org/) will be used. Randomization will be done by a biostatistician outside the researcher. Patients who meet the inclusion criteria and agree to participate in the study will be assigned to the experimental and control groups according to the randomization list. Before the operation, the patient will be visited and information will be given about the purpose, content and intervention to be applied. After obtaining verbal and written permission from the patients who accepted to participate in the study, the "Informed Consent" will be filled in the "Patient Identification form. On the day of surgery, "surgical intervention information will be filled in by the researcher. In the postoperative period at the 2nd, 4th, 6th, 12th and 24th hours, the patient will use ginger and peppermint oil as inhalation. At the end of the 24th hour, the application will be terminated. In the control group, no application will be made during and after the surgical intervention, and routine treatment and care will be applied. After admission to the clinic of the patients in the experimental and control groups, the severity of pain, nausea and vomiting, the number of nausea-vomiting at the 2nd, 6th, 12th and 24th hours, the name, dose, frequency and time of the antiemetic drugs used were determined by the researcher. At the end of the 24th hour, Rhodes Nausea Vomiting Index score will be evaluated by the researcher.
