The purpose of this study is to see whether altering the angle of the Magill forceps by 45 degrees will affect nasal intubation time in pediatric dental surgery patients.

The null hypothesis is that their will be no difference between the nasal intubation times of those patients intubated with the conventional Magill forceps and those intubated with the altered Magill forceps.

The Magill forceps (MF) is the instrument of choice for nasal tracheal intubation (NTI). It serves as an aid for inserting the endotracheal tube tip past the vocal cords during NTI. NTI is preferred over oral tracheal intubation (ETT) in certain instances such as pediatric dental surgery. This is because NTI permits excellent access to all intraoral structures while reducing risk of inadvertent displacement of an orotracheal tube. Although there is literature looking at MF design alterations to reduce complications and improve its other uses, there is no literature examining the effect of design alterations on time to successful intubate (TTI). Our study premise is based on the concept that a MF is not ideally structured for the pediatric airway anatomy. Knowing that the larynx is considerably anterior in the pediatric airway, we hypothesized that a + 45° angle change 2cm from the tip of the MF will help align the direction the instrument carrying the endotracheal tube with the anatomic direction of the airway and thus help reduce the TTI.. If a reduction in TTI can be shown it would be of significant benefit and could add another tool for NTI. Even though, the current MF has been satisfactory in its use, this should not deter us from looking for opportunities to improve on the current standard. To test this hypothesis, we will include a hundred participants as part of an open label, controlled, single center, and randomized study in which 50 patients will be intubated with the conventional MF and 50 patients will be intubated with the altered MF. We expect the results to show at least a 5 second reduction in TTI and thus be statistically significant with a p value less than 0.05 for our sample size. Our expected conclusion is that a reduced TTI is clinically beneficially as it will reduce apnea time in the pediatric patients, a population with known physiological limitations in respiratory reserve. This, in turn, could point to a reduction in intra-operative and post-operative respiratory complications.
