Clinical Trial Summary

In this study we compared the intubation success, time needed for intubation, subglottic damage, postoperaitve sore throat, hoarseness and hemodynamic response to orotracheal intubation using three different intubation stylets with C-MAC R videolaryngoscope D- blade.

Description:

In this study we compared the intubation success, time needed for intubation, subglottic damage, postoperaitve sore throat, hoarseness and hemodynamic response to orotracheal intubation using three different intubation stylets with C-MAC R videolaryngoscope D- blade. After the approval of the Ethics Committee, patients were randomized into three groups with closed envelope technique. In Group A endotracheal tube (ETT) is shaped into an angel of 90 degrees, in Group B 80 degrees and in Group C 60 degrees with three different stylets. Laryngoscopy was performed using D-Blade in all 3 groups. Heart rate and blood pressure before and after intubation, time from the entrance of the laryngoscope into the mouth to the passage of the vocal cords, time from the appearance of the cords to intubation, Cormack-Lehane (C-L) classification were recorded. Subglottic damage was examined with fiberoptic bronchoscope. Patients were evaluated regarding postoperative sore throat and hoarsness at 30 minutes, 4, 12, 24 hours postoperatively.

Intervention

Other:
• Intubation using C-MAC D blade videolariyngoscope
all patients were intubated using the C-MAC D-Blade videolaryngoscope but for each group the intubation tubes were angled in different degrees. First group was intubated using the stylet of 60 degrees, second group was intubated using the stylet of 80 degrees and the third group was intubated using the stylet of 90 degrees.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	sore throat	For evaluation of sore throat, the patients were asked whether they had any throat pain. The severity of sore throat was graded as follows: 1: no sore throat, 2: minimal, 3: moderate, 4: severe	30 minutes, 4 hour, 12 hour, 24 hour
Secondary	Intubation success rate	For evaluation of the success rate modified intubation difficulty score was used.	2 minutes
Secondary	Subglottic damage	For evaluation of subglottic damage 4-point scaled subglottic damage score was used. grade 0, normal; grade 1, mucosal hyperaemia and oedema and/or slight submucosal haematoma; grade 2, moderately submucosal haematoma; grade 3, mucosal laceration and/or mucosal bleeding	2 hours
