Comparing Video and Direct Laryngoscopy for Nasotracheal Intubation

Abstract

This parallel group randomized controlled clinical trial compared intubation duration and success using video laryngoscopy (VL) versus direct laryngoscopy (DL) during routine nasotracheal intubation. Fifty patients undergoing oral and maxillofacial surgery under general anesthesia were randomly assigned into 2 groups receiving either VL or DL to facilitate nasotracheal intubation. The primary outcome was the amount of time required to complete nasotracheal intubation. The secondary outcomes included the success of first attempt at intubation and the use of Magill forceps. Results demonstrated a mean time to intubation of 142 seconds in the DL group and 94 seconds in the VL group (p = .011). First attempt intubation success was 92.0% in the VL group and 84.0% in the DL group (p = .34). The use of Magill forceps was significantly increased in the DL group (p = .007). VL for routine nasotracheal intubation in oral and maxillofacial surgery procedures results in significantly faster intubation times and decreased use of Magill forceps compared with traditional DL.
