Use of McGrath Videolaryngoscope to Assist Transesophageal Echocardiography Probe Insertion in Intubated Patients

Use of McGrath Videolaryngoscope to Assist Transesophageal Echocardiography Probe Insertion in Intubated Patients: A Prospective Randomized Controlled Trial

The primary aim of this study is to investigate the difference in the first attempt and overall success rate of different techniques for insertion of transesophageal echocardiography. Secondary aim is to investigate the difference of the duration of insertion using the selected technique, complications during insertion such as oropharyngeal mucosal injury and hematoma.

Study Overview

• Status: Completed
• Conditions: Other Complications of Surgical and Medical Procedures
• Intervention / Treatment: Device: conventional technique; Device: videolaryngoscope technique

Detailed Description

Eighty adult patients, who received general anaesthesia for elective open heart surgeries that required transesophageal echocardiography insertion, will be randomized by means of a computer-generated randomization order into two groups: Conventional group (Group C), and videolaryngoscope group (group VL).

Success rate of the selected technique (first attempt and overall), duration of insertion for selected technique, complications such as oropharyngeal mucosal injury and hematoma will be noted.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
difference in the first attempt and overall success rate	investigate the difference in the first attempt and overall success rate (with percentage) of different techniques for insertion of transesophageal echocardiography probe.	participants will be followed from the beginning of the transesophageal echocardiography probe insertion through the mouth to the confirmation of successful insertion (10 minutes)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
difference of the duration of insertion and complications during insertion	investigate the difference of the duration of insertion (in seconds) using the selected technique and complications (with number and percentage) during insertion such as oropharyngeal mucosal injury and hematoma.	participants will be followed for the duration of intraoperative period and postoperative 8 hours.
