Effect of Cuff Pressure of Endotracheal Tube on POST

Study Overview
=================
Brief Summary
-----------------
The main objective of this study is to evaluate the association between the duration of intraoperative cuff overpressure and the development of postoperative sore throat.

Detailed Description
-----------------
For patients undergoing laparoscopic surgery after tracheal intubation, continuous cuff pressure monitoring is performed by connecting a pressure monitor to the cuff of the endotracheal tube. The incidence of postoperative sore throat was evaluated via direct questioning in all patients. This study aimed to investigate the association between the development of postoperative sore throat and the duration of overpressure in the cuff of the endotracheal tube.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of postoperative sore throat at 24h postoperatively. | Incidence of postoperative sore throat (score 1 or more) 0 = no sore throat = mild sore throat (less severe 1 = mild sore throat (less severe than with a cold) = moderate sore throat (as with a cold)2 = moderate sore throat (as with a cold) = severe (more severe than with a cold)3 = severe (more severe than with a cold) | at 24h postoperatively. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of postoperative sore throat at 1h postoperatively. | Incidence of postoperative sore throat (score 1 or more) 0 = no sore throat = mild sore throat (less severe 1 = mild sore throat (less severe than with a cold) = moderate sore throat (as with a cold)2 = moderate sore throat (as with a cold) = severe (more severe than with a cold)3 = severe (more severe than with a cold) | at 1h postoperatively | 
| Incidence of postoperative sore throat at 48h postoperatively. | Incidence of postoperative sore throat (score 1 or more) 0 = no sore throat = mild sore throat (less severe 1 = mild sore throat (less severe than with a cold) = moderate sore throat (as with a cold)2 = moderate sore throat (as with a cold) = severe (more severe than with a cold)3 = severe (more severe than with a cold) | at 48h postoperatively | 
| Incidence of postoperative hoarseness at 1h postoperatively. | Incidence of postoperative hoarseness (score 1 or more) 0 = no hoarseness = mild hoarseness (noticed by the patient only) = severe hoarseness (noticed by the time of the interview by the personnel) = aphonia (inability to speak) | at 1h postoperatively | 
| Incidence of postoperative hoarseness at 24h postoperatively. | Incidence of postoperative hoarseness (score 1 or more) 0 = no hoarseness = mild hoarseness (noticed by the patient only) = severe hoarseness (noticed by the time of the interview by the personnel) = aphonia (inability to speak) | at 24h postoperatively. | 
| Incidence of postoperative hoarseness at 48h postoperatively. | Incidence of postoperative hoarseness (score 1 or more) 0 = no hoarseness = mild hoarseness (noticed by the patient only) = severe hoarseness (noticed by the time of the interview by the personnel) = aphonia (inability to speak) | at 48h postoperatively |
