Overview

In this study we compared post-operative sore throat, ease and time of intubation, hoarseness, subglottic damage and hemodynamic changes to orotracheal intubation using three different intubation stylets with C-MAC R videolaryngoscope D- blade.

In this study we compared the ease of intubation, 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.

Intubation using C-MAC D blade videolariyngoscopeOTHER

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.

Outcomes

Primary Outcomes

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

Time frame: 30 minutes, 4 hour, 12 hour, 24 hour

Secondary Outcomes

Ease of intubation

For evaluation of the ease of intubation modified intubation difficulty score was used.

Time frame: 2 minutes

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

Time frame: 2 hours
