Intervention model description: Three groups with control group (The study was planned as an open-label, randomized, controlled, parallel group interventional study. Participants will be randomly assigned to groups.)
Primary purpose: HEALTH_SERVICES_RESEARCH

Brief summary: The aim of the study was to determine the effect of postoperative menthol ice and frozen saline applications on thirst and sore throat in patients undergoing lumbar disc surgery.

Detailed description: In the postoperative period, patients become susceptible to many complications that may develop due to general anaesthesia, endotracheal intubation, surgical intervention and clinical conditions. One of the conditions that patients experience quite intensely in the postoperative period and which is usually ignored in clinics is the feeling of thirst. Another problem that may occur in patients undergoing surgery under general anaesthesia is discomfort due to endotracheal intubation. Patients may experience problems such as sore throat, hoarseness, difficulty swallowing and dry throat in the postoperative period due to endotracheal intubation. Diagnosis and control of postoperative thirst and sore throat contribute to patient comfort and prevention of complications. This study is considered important because it draws attention to postoperative thirst and sore throat, a problem that surgical patients have.
