Abstract Background Patients undergoing oral and maxillofacial surgeries under general anesthesia usually require nasotracheal intubation. When presented with patients with equally patent nostrils, selection of the nostril to use for intubation is an important decision for facilitating intubation. The objective of this trial is to determine whether choice of nostril impacts nasotracheal intubation when using a video rigid stylet in patients undergoing oral and maxillofacial surgery. Methods Fifty patients scheduled for elective oral and maxillofacial surgery requiring nasotracheal intubation were randomly allocated into two groups to undergo nasotracheal intubation through the left nostril (Group L, n = 25) or the right nostril (Group R, n = 25). Intubation was performed by experienced anesthesiologists using a video rigid stylet. The primary endpoint was time to successful intubation, which was defined as the duration from when the tip of the stylet-tube assembly entered the selected nostril to when the tube entered the trachea. Secondary outcomes included: length of time for device insertion; length of time for tube insertion; total success rate; first-attempt success rate; number of intubation attempts; requirement of airway assisted maneuvers; incidence and severity of epistaxis. Intubation-related adverse events were monitored for up to postoperative 24 h. Results Median time (interquartile range) to tracheal intubation was 25.3 seconds (20.7 to 27.6) in Group L and 26.8 seconds (22.5 to 30.0) in Group R (median difference (MD) = 1.9; 95% confidence interval (CI) –1.8 to 5.7, P = 0.248). Nasotracheal intubation was successful in all patients in both groups and the first-attempt success rates in both groups were similar (Group L: 96% (24/25); Group R: 96% (24/25); relative risk (RR) 1.0; 95% CI 0.9 to 1.1; P > 0.999). No significant difference of requirement of assisted maneuvers was noted between the two groups (Group L: 36% (9/25); Group R: 28% (7/25); RR 0.8; 95% CI 0.3–1.8; P = 0.544). Furthermore, all patients showed a high quality of visualization of the glottis (Cormack and Lehane Grade I). For safety outcomes, the incidence and severity of epistaxis during intubation was comparable between the two groups. There were no significant differences between the selection of nostrils and intubation-related adverse events up to 24 h after surgery. Conclusions When considering which nostril to use for intubation with video rigid stylet, either nostril can be used similarly. Trial registration Clinicaltrials.gov . Identifier: NCT05218590. |
