By Marwah Maher Sabah Radhi, Hassan Sarhan Haider and Dr Aya Raad Salman Abu Altemen.
Abstract
Background
Nasal intubation is a commonly used method of intubation for oral & maxillofacial surgeries as it allows better surgical access & isolation for oral procedures. The classical & most common method to guide the endotracheal tube tip into the larynx is through the use of Magill forceps.
Aim
to study: the use of cuff inflation technique to guide the tip of the endotracheal tube into the larynx instead of use of Magill forceps, in nasotracheal intubation. Patients & method: This prospective interventional case series was conducted on 62 patients, all were scheduled for elective maxillofacial surgery under general anesthesia, after preoxygenation and induction of anesthesia, Cormack & Lehane grading was assessed and the tube was introduced through the selected nostril until loss of resistance and the endotracheal tube tip reached the oropharynx, direct laryngoscopy was done and the tube cuff was inflated with 15ml of air to elevate tube tip from the posterior pharyngeal wall to be advanced gently into laryngeal inlet then it was deflated and advanced into the trachea and cuff was reinflated. Patients were classified into 3 grades according to difficulty of intubation (easy, requires external manipulation or tube rotation, requiring Magill forceps for intubation).
