Clinical Trial Summary

Objectives: To compare the safety and efficacy of Parker flex-it directional stylet (PFDS) versus conventional malleable stylet (CMS) in orotracheal intubation (OTI) using fiber-optic Macintosh laryngoscope. Background: OTI is used in general anesthesia for anesthetic delivery and ventilation of patients. OTI delay or failure may adversely affect patient outcomes, therefore, anesthetists with sufficient clinical experience and skill should perform OTI. However, in emergency situations, experienced anesthetists may not be available, and the patient may have a high Cormack-Lehane grade. A stylet is commonly used in the emergency department to aid insertion of the endotracheal tube during direct laryngoscopy. Patients and Methods: This was a prospective, randomized, double-blind, phase four clinical trial; carried out on 60 patients requiring OTI under general anesthesia at our hospital. Patients were randomly allocated into two equal groups; group DS, intubated using PFDS, and group MS, intubated using CMS.
