Abstract

Background:
Laryngoscopes are the potential cause of cross-contamination between patients. A considerable way to prevent this problem is to use of disposable laryngoscope’s blades. This study was designed to evaluate laryngoscopic conditions in pediatrics with disposable and metalic Macintosh blades.
Methods:
152 children scheduled for elective surgery aged 3-12 years were enrolled in this randomized clinical trial. After induction of anesthesia, anesthesiologist intubated the patients with one of two kinds of laryngoscope’s blades (disposable or metalic Macintosh). During laryngoscopy and tracheal intubation, glottic view, brightness of laryngoscopic field, time of intubation and satisfaction degree of anesthesiologist was recorded.
Findings:
All patients were successfully intubated. There was significant difference between disposable and metalic Macintosh blades with respect to time of intubation and brightness of laryngoscopic field. Grade I of laryngoscopy was more frequent in metalic group compared to disposable group (83% vs. 49%) Anesthesiologist satisfaction was significantly improved during laryngoscopy with metalic Macintosh blade.
Conclusion:
With respect to successful tracheal intubation of all patients in this trial and the usefulness of disposable laryngoscopes to prevent cross-contamination between patients and regardless of significant difference in laryngoscopic conditions between disposable and metalic blades, disposable laryngoscopes can be used under normal intubating conditions in pediatrics.
