Intubating Video Stylet Versus Fiberoptic Intubating Bronchoscope.

Intubating Video Stylet Versus Fiberoptic Intubating Bronchoscope. A Randomised Comparative Study for Intubation in Lateral Position.

the video stylet (VS), it is considered one of the newer devices in this category. It is a portable device with liquid crystal-display module screen for visualization of vocal cords. It is considered an alternative to the flexible fiberoptic endoscope especially in the developing countries where the device cost is the main limiting factor. It has many benefits such as being light weight, easy to clean, durable, chargeable, less expensive and reusable. However newer video stylet devices have not been formally evaluated for tracheal intubation in case of laterally positioned patients.

Following approval from Ethics and Research Committee of Theodor Bilharz Research Institute, the study protocol will be explained to the patients after taking their consent.

Upon arrival to the operating room, a 20 G cannula will be sited intravenously and infusion of Ringer's solution will be started. Intravenous midazolam in a dose of 0.05 mg/ Kg will be given. Then, a five-lead electrocardiogram (GE-Datex Ohmeda 5 lead ECG cable), a pulse oximeter (GE- Datex Ohmeda adult finger spO2 sensor) and a non-invasive blood pressure monitor (GE-Datex Ohmeda NIBP cuff, adult double tube with bag) will be attached to the patient.
