Nasotracheal intubation(NTI) has a high rate of nasal trauma. Various methods like prewarming the tube, using red rubber catheter to railroad tube were used to reduce trauma. Gum elastic bougie (GEB) is one such technique, when used as a conduit has shown to reduce post intubation nasopharyngeal trauma. <h3>Methods</h3> A Prospective interventional randomized control trial was conducted from 31/10/2018 to 31/05/2021 at a tertiary health care hospital in New Delhi. After obtaining Ethical clearance from the institutional committee, patients were randomly allocated by closed envelope technique into two groups, group B and group NB with 45 participants each. In group B, Gum elastic bougie was used to guide the endotracheal tube while in group NB, no such adjunct was used. The main aim of the study was to compare the incidence and severity of nasopharyngeal bleeding adult patients undergoing elective surgery. The other parameters observed were time taken for intubation and ease of intubation. <h3>Results</h3> The grade of bleeding at 1 min and 5 min after intubation was significantly lower in the group B as compared to group NB. The time taken for intubation was significantly lower in the group B. The ease of intubation was comparable in both the groups. <h3>Conclusions</h3> The study concluded that Videolaryngoscopic assisted bougie guided NTI with a GEB in adult patients reduces the incidence and severity of nasopharyngeal trauma after intubation. It does not increase the time taken for nasotracheal intubation.
