Summary

The goal of this clinical trial is to compare cuff inflation deflation method versus conventional method using Magill forceps in adult patients scheduled for elective surgery dental or maxillofacial that need nasal intubation. The study question: Is cuff inflation deflation method for nasal intubation takes a short time than the conventional method using Magill forceps in adult patients scheduled for elective surgery dental or maxillofacial? We will compare the inflation deflation technique with the Magill forceps technique for nasal intubation in adult patients to see if the inflation deflation technique will take less time and associated with less side effects like cuff perforation and mucosal injury. Participants will \[describe the main tasks participants will be asked to do, interventions they'll be given and use bullets if it is more than 2 items\].

Detailed description

Magill forceps is used to maneuver the endotracheal tube (ETT) in the posterior oropharynx and place its tip into the laryngeal inlet. While the Magill forceps are useful in guiding the nasotracheal tube past the vocal cords, care must be taken to avoid excessive maneuvering in order to minimize the risk of local trauma and rupture of the nasotracheal tube balloon. Cuff inflation-deflation method can reduce the apnea time in the adult patients. This, in turn, could point to a reduction in the complications (as desaturation and cardiac arrhythmia) that associated with the prolonged-time procedure. Written informed consent will be obtained from all patients participating in the trial. The trial will be registered prior to patient enrollment. Ninety patients between the ages of 18 and 60 years with American Society of Anesthesiologists (ASA) physical status I -II , scheduled for elective surgery (dental and maxillofacial) will be enrolled in a prospective randomized observer blinded clinical trial. Patients, who have coagulopathies, have upper airway abnormalities, at risk for aspiration or patient's refusal will be excluded from the study. Materials and methods Airway management is subdivided into phases: Phase 1 :Passage of the endotracheal tube through the nose into the pharynx Phase 2 : Video-laryngoscope-guided passage of the endotracheal tube through the pharynx into the trachea. Patients will be randomized into 2 groups according to phase 2: Group A (45 patients) will be performed with tracheal tube cuff inflation-deflation method. Tracheal tube cuff will be inflated with 15-20 ml of air (volume of air is depending on the level of larynx). Once the tip of ETT at the laryngeal inlet, the cuff of ETT will be deflated and advanced into the trachea. Group 2 (45 patients) will be performed using the Magill forceps to guide the ETT tip to pass through the pharynx and glottis into the trachea. Patients will be randomly assigned on a one-to-one ratio. Randomization will be performed outside the study center by means of a computer generated random- numbers table. Group allocation will be concealed in sealed opaque envelopes that will not be opened till the last practical moment. The nasal intubation will be performed behind an opaque screen so that observer could not see which approach will be used. All procedures were performed preoperatively by the attending anesthetists, who have the same substantial expertise (at least 3 years) in the video laryngoscopy assisted nasal intubation in adult patients. Patient demographics, type and duration of surgery, and the patient's ASA physical status will be recorded.
