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.

Study Groups

Menthol ice group

The menthol ice group will be given menthol ice by the researcher.

Group Type: EXPERIMENTAL

Menthol ice

Intervention Type: OTHER

When patients are brought from the operating theatre to the surgical clinic, patients will be waited until they are able to communicate. In the first stage, after filling in the Patient Identification Form before the intervention, thirst status with Perioperative Thirst Discomfort Scale (PTDS) and sore throat status with the Numerical Pain Scale (NPS) will be evaluated. In the second stage, evaluation will be made according to the Safety Protocol for the Management of Immediate Postoperative Thirst and menthol ice will be applied if the patients meet the criteria in the protocol. Thirst will be re-evaluated with PTDS and sore throat will be re-evaluated with NPS at 30th and 60th minutes after the first application. Immediately after this evaluation, menthol ice will be applied for the second time. After the second application, thirst will be re-evaluated with PTDS at 30th and 60th minutes and sore throat will be re-evaluated with NPS.

Frozen saline group

The frozen saline group will be given frozen saline by the researcher.

Group Type: EXPERIMENTAL

Frozen saline

Intervention Type: OTHER

When patients are brought from the operating theatre to the surgical clinic, patients will be waited until they are able to communicate. In the first stage, after filling in the Patient Identification Form before the intervention, thirst status with Perioperative Thirst Discomfort Scale (PTDS) and sore throat status with the Numerical Pain Scale (NPS) will be evaluated. In the second stage, evaluation will be made according to the Safety Protocol for the Management of Immediate Postoperative Thirst and frozen saline will be applied if the patients meet the criteria in the protocol. Thirst will be re-evaluated with PTDS and sore throat will be re-evaluated with NPS at 30th and 60th minutes after the first application. Immediately after this evaluation, frozen saline will be applied for the second time. After the second application, thirst will be re-evaluated with PTDS at 30th and 60th minutes and sore throat will be re-evaluated with NPS.

Control group

There will be no intervention to the control group. Routine practices of the clinic (moisturizing the lips with wetgauze, cotton or tissue) will be performed by the nurses of the Surgery Clinics.

Group Type: OTHER

No Interventions

Intervention Type: OTHER

When patients are brought from the operating theatre to the surgical clinic, patients will be waited until they are able to communicate. In the first stage, after filling in the Patient Introduction Form before the intervention, thirst status with Perioperative Thirst Discomfort Scale (PTDS) and sore throat status with Numerical Pain Scale(NPS) will be evaluated. Patients in the control group will be waited for approximately 10 minutes, taking into account the application times in the intervention groups. No intervention will be applied during the waiting period. After 10 minutes of waiting time, thirst will be re-evaluated with PTDS and sore throat will be re-evaluated with NPS at 30th and 60th minutes. Considering the 2nd application time in the intervention groups, it will be waited again for approximately 10 minutes without any intervention. After the waiting period, thirst will be re-evaluated with PTDS at 30th and 60th minutes and sore throat will be re-evaluated with NPS.
