Evaluation of intubating conditions using stylet by conventional through-tube technique and through Murphy's eye in patients with high Mallampati scores

Natl J Maxillofac Surg. 2014 Jan;5(1):14-8. doi: 10.4103/0975-5950.140149.

Abstract

Background: Difficult intubation is always a nightmare for an Anaesthetist. This study was planned to study the alternative method of stylet use during difficult oro-tracheal intubation. Outcome measures assessed were ease of intubation, hemodynamic stability and reducing complications.

Materials and methods: A cohort of 60 patients of Mallampati class III patients was formed and patients were divided into two groups. In group 1 patients, conventional through tube method was used for inserting stylet, whereas, in group 2 patients, Murphy's eye was used for inserting malleable flexi tip stylet.

Results: Hemodynamic stability in terms of mean arterial blood pressure and heart rate was observed in group 2. Intubating time, number of attempts of successful intubation and post operative pharyngo-laryngeal complications was also low in group 2 patients.

Conclusion: The use of Murphy's eye to pass stylet during difficult airway manoeuvre is a safe alternative over conventional rail-road technique.
