Abstract: 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 metallic Miller blades. One hundred and fifty two children scheduled for elective surgery aged 3-12 years were enrolled in this randomized, clinical trial. After induction of anesthesia, patients were randomly intubated with either disposable or metallic reusable Miller blade. During laryngoscopy and tracheal intubation, glottic view, brightness of laryngoscopic field, duration of laryngoscopy and satisfaction degree of anesthesiologists was recorded. All patients were successfully intubated. There was significant difference between disposable and metallic Miller blades with respect to brightness of laryngoscopic field. Grade I and II of laryngoscopy in metallic group was significantly different compared to disposable group (66 and 32% vs. 50 and 49%). There was no significant difference between disposable and metallic groups with respect to anesthesiologist satisfaction and duration of laryngoscopy. With respect to successful tracheal intubation of all patients in this trial and the usefulness of disposable laryngoscopes to prevent cross-contamination between patients, Topster disposable laryngoscope can be used under normal intubating conditions in pediatric patients.
