About

Postoperative sore throat (POST) is a common and undesirable postoperative symptom that causes patient dissatisfaction. Cold application is a non-invasive, non-pharmacological, cost-effective and effort-effective therapy for pain management. The aim of this study was to evaluate whether colding of ETT can reduce sore throat, dysphagia and dysphonia after endotracheal intubation.

Full description

The incidence of postoperative sore throat (POST) has been reported up to 62% following general anaesthesia.It is an undesirable events experienced by patients after general anaesthesia. Various pharmacological agents have been applied to reduce POST, such as lidocaine, ketamine, magnesium, corticosteroids or non-steroidal anti-inflammatory drugs. However, these agents may have some systemic and local side effects. Therefore, various non-pharmacological applications have been investigated to reduce sore throat. Cold application is a non-invasive, cost-effective and effort-effective therapy for pain management. Although the mechanism is not clearly known, it increases the pain threshold, slows cellular metabolism, causes vasoconstriction, and reduces capillary permeability. Therefore, we hypothesized that colding of endotracheal tube may decrease POST associated with airway inflammation. The aim of this study was to evaluate whether colding of ETT can reduce sore throat, dysphagia and dysphonia after endotracheal intubation. The goal of this study is to identify a simple, safe, and inexpensive perioperative intervention to reduce post operative sore throat. This study is a prospective, randomised study involving 116 subjects and they will assessed on the incidence and severity of sore throat, dysphagia and dysphonia at 1. 4. 12. 24. hours after removal of endotracheal tube. Outcomes from this study can be extended to patients who will be receiving general anaesthesia using a endotracheal tube to reduce the incidence and severity of sore throat.
