A Comparative Study on the Effect of Endotracheal Intubation in Three Methods of Oral, and Nasal with and without the Help of Magill Forceps, on Heart Rate and Blood Pressure in Patients Undergoing Maxillofacial Surgery

Background: The purpose of this study was to compare the effect of endotracheal intubation in three methods of oral, and nasal with and without the help of Magill forceps, on heart rate and blood pressure in patients undergoing maxillofacial surgery. Methods: In this single-blind randomized clinical trial study, 96 patients who underwent facial and maxillofacial surgery, were randomly divided into three groups of oral, and nasal (with or without the use of Magill forceps) endotracheal intubation. Heart rate and blood pressure were studied in patients before the intubation, and 0, 1, 2, 5, and 10 minutes after it, and post-tubal complications were assessed as well. Findings: There was no significant difference between the three groups based on heart rate, and systolic and diastolic blood pressure (P > 0.05 for all). Throat wound in the oral intubation group, and epistaxis in nasal intubation group without help of Magill forceps was significantly higher than in other groups (P < 0.05). Moreover, the duration of intubation in the oral procedure was significantly lower than other methods (P < 0.05). Conclusion: All three methods of oral, and nasal, with and nose without the help of Magill forceps, cause similar changes in heart rate and blood pressure. The only difference between these three methods is the side effects caused by intubation.
