The Effect on Thirst, Nausea-Vomiting and Comfort Levels of Menthol Lozenge Applied After Extubation

The Effect on Thirst, Nausea-Vomiting, Hemodynamic Parameters, and Comfort Levels of Menthol Lozenge Applied After Extubation to Patients to Undergoing Cardiovascular Surgery

It is reported that approximately 17.5 million people die worldwide each year due to cardiovascular diseases, including ischemic heart disease, cerebrovascular disease and rheumatic heart disease. The most preferred method in the treatment of coronary artery disease is Coronary Artery Bypass Graft (CABG) surgery. This procedure routinely requires general anesthesia and endotracheal intubation. Patients due to these practices often experience nausea-vomiting and thirst after extubation. It is stated that menthol application, which is a low cost, easy to apply and safe method, can be effective in the management of these complications. As a result of the literature review, there is no study evaluating the effectiveness of the menthol lozenge in quenching thirst after extubation and in the management of nausea and vomiting. In this study, it is aimed to develop methods that accelerate the postoperative recovery by proving the effect of oral menthol lozenge intake after extubation on thirst, nausea-vomiting, physiological parameters and comfort level in patients undergoing CABG surgery. The universe of this randomized controlled study was planned by Dr. Siyami Ersek Thoracic and Cardiovascular Surgery Training and Research Hospital will create patients who underwent CABG surgery. His sample, on the same dates, was Dr. Siyami Ersek Thoracic and Cardiovascular Surgery Training and Research Hospital will create a total of 118 patients hospitalized in the Cardiovascular Surgery (Postoperative) Intensive Care Unit and undergoing CABG surgery that meet the inclusion criteria. Participants will be divided into two equal groups as intervention (n = 59) and control (n = 59) groups. Patient Information Form, Intraoperative Patient Evaluation Form, Visual Analogue Scale (VAS) for evaluation of thirst and nausea-vomiting, Physiological Parameter Control Form, Analgesic-Antiemetic Use Control Form, General Comfort Scale Short Form will be used for data collection. The intervention group will be given a lozenge containing menthol orally at the 30th, 60th and 90th minutes after extubation. Thirst, nausea-vomiting, physiological parameters, analgesic and antiemetic consumption and comfort levels of all patients will be evaluated. The data obtained from the study will be analyzed with appropriate statistical methods using the SPSS for Windows 22.0 program (Statistical Package for the Social Sciences).

Study Overview

• Status: Completed
• Conditions: Nausea; Vomiting; Thirst
• Intervention / Treatment: Other: Menthol Lozenge

Detailed Description

The aim of this study is to determine the effect of oral menthol lozenge administered after extubation on thirst, nausea-vomiting, physiological parameters and comfort level, as well as analgesic and antiemetic consumption in patients who underwent cardiovascular surgery. With this research, it is aimed to increase patient comfort by providing evidence of the effect of low-cost oral menthol lozenge intake on the feeling of thirst, nausea-vomiting, analgesic and antiemetic integration after extubation on physiological parameters.

Practices aimed at eliminating many problems such as thirst, sore throat, nausea and vomiting experienced in the early postoperative period positively affect the physical, psychospirical, environmental, sociocultural comfort of the patient and strengthen their health-oriented behaviors. It has been reported that there is a relationship between health-enhancing behaviors and providing comfort. It is observed that patients who undergo surgical procedures experience many problems in the postoperative period, their comfort level decreases and they are widely affected, from prolonged hospital stay to mortality. There are many studies in the literature aimed at accelerating the recovery in the perioperative process and increasing patient satisfaction.

Complications such as thirst and nausea and vomiting, which are seen in the postoperative period and can be quite disturbing by patients, can be overlooked in clinical observations. It is planned to prove the effectiveness of the use of low-cost and easy-to-apply menthol lozenge in the management of these complications. In the light of the literature review, menthol was found to be effective in gastrointestinal system disorders, pain management, and dehydration. The use of oral menthol containing lozenge in quenching thirst after extubation, in the management of postoperative nausea and vomiting, and in improving patient comfort, as well as analgesic-antiemetic consumption and evaluation of physiological parameters are the original value of this study.

The universe of the research was carried out by Dr. Siyami Ersek Thoracic and Cardiovascular Surgery Training and Research Hospital will create patients who underwent CABG surgery. His sample, on the same dates, was Dr. Siyami Ersek Thoracic and Cardiovascular Surgery Training and Research Hospital will create a total of 118 patients hospitalized in the Cardiovascular Surgery (Postoperative) Intensive Care Unit and undergoing CABG surgery that meet the inclusion criteria.

Sampling calculation was done with G Power 3.1.9.7 package program. Based on the VAS score averages in the study conducted by Aydın (2016), the sample that will represent the population was calculated as 0.05 significance level, the power of the study 80% and the effect size 0.46 (medium level) at the 95% confidence interval. As a result of the statistical analysis, it was calculated that the study should be carried out with a minimum of 118 patients, 59 in the experimental group and 59 in the control group.
