The Effect of Cold Vapor Application on Postoperative Sore Throat

Study Overview
=================
Brief Summary
-----------------
To determine the effect of cold vapor given in the post-extubation period on sore throat.

Detailed Description
-----------------
General anesthesia increases the comfort of the patient by ensuring that the patient does not feel the surgical interventions and pain during the operation. The necessity of intubation is known in patients who have undergone surgery under general anesthesia. Intubation provides benefits such as keeping the airway open, controlling the airway and breathing, reducing respiratory effort and dead space volume, preventing aspiration, and facilitating resuscitation in case of any problem. Although surgical interventions are an important treatment option for health problems, postoperative complications such as sore throat, dry throat, hoarseness and dysphagia due to laryngeal and pharyngeal traumas caused by intubation are frequently observed especially in patients receiving general anesthesia. Although it is seen in the literature that pharmacological, non-pharmacological and herbal methods are applied to reduce postoperative sore throat, there are not enough studies examining the effect of cold steam application on sore throat. With this research, it is expected that the cold steam given in the postoperative period will contribute to the relief of sore throat.

Design Details

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Patients were divided into intervention and control groups using a simple randomized control method.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention group<br>Cold vapor was applied 3 times in total at 0th,2nd and 6th hours. | Procedure: Cold vapor<br>* The Ramsey Sedation Scale was used to assess wakefulness after patients were extubated and arrived at the recovery unit at the 0th hour postoperatively. Sore throat, localization of pain, hoarseness, dry throat, and swallowing difficulty were evaluated in patients with a score of 2 according to this scale. Sore throat of the patients was evaluated with Numerical Rating Scale. Then, cold vapor was applied for 15 minutes with a vapor machine used as a standard in the hospital by the researcher. After the cold vapor application was finished, the patients' sore throat, localization of pain, hoarseness, swallowing difficulty and dry throat were re-evaluated with the same forms. Sore throat were evaluated before the application of cold vapor at the 2nd and 6th hours. Then cold vapor was applied for 15 minutes. After the cold vapor application was finished, sore throat were re-evaluated. At the 24th hour, cold vapor was not applied to the patients. Only sore throat were evaluated.<br>|
| No Intervention: Control group<br>No cold vapor was applied at 0th,2nd and 6th hours. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sore throat | In our study, a horizontally prepared Numerical Rating Scale was used to evaluate the severity of pain. Patients participating in the study were asked to rate the severity of their sore throat on a scale of 0 to 10. The scale begins with the absence of pain (0) and ends with excruciating pain (10). When the patient came to the recovery unit, the severity of sore throat was evaluated before and after the application of cold vapor at 0th hour. | Within an hour after surgery | 
| Sore throat | In our study, a horizontally prepared Numeric Rating Scale was used to evaluate the severity of pain. Patients participating in the study were asked to rate the severity of sore throat between 0 and 10. The scale starts with the absence of pain (0) and ends with unbearable pain (10). The severity of sore throat was evaluated before and after the application of cold vapor at 2nd hour postoperatively. | 2nd hour after surgery |

Patients participating in the study were asked to rate the severity of sore throat between 0 and 10. The scale starts with the absence of pain (0) and ends with unbearable pain (10). The severity of sore throat was evaluated before and after the application of cold vapor at 6th hour postoperatively. | 6th hour after surgery |

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hoarseness | To assess hoarseness, patients were asked a single question, Do you have any hoarseness in your voice now? Participants were asked to evaluate this question with a 4-point Likert-type rating.Rating; 0 = no hoarseness, 1 = slow, hoarse voice, 2 = moderate hoarseness (clear during the interview), 3 = hoarseness (completely silent, no speech). When the patient came to the recovery unit, the severity of hoarseness was evaluated before and after the application of cold vapor at the 0th hour. | Within an hour after surgery |
