“…If the adjustment still did not help, intubation was performed with the assistance of a stylet. 15 The operator removed the tracheal tube and inserted a hard stylet. An arc of about 80° was formed at the cuffs so that the tracheal tube was shaped like a hockey stick.…”

What is known and objective: Prior to nasotracheal intubation (NTI), topical nasal vasoconstrictors are used to prevent NTI-related epistaxis (NTIRE). Since we learned that there is no significant increase in NTIRE among hypertensive patients undergoing NTI with adequate lubrication but without vasoconstrictors, we initiated this randomized controlled study to assess the necessity of vasoconstrictor use in reducing NTIRE. Methods: Patients with the American Society of Anesthesiologists Physical StatusClassification 1 and normal coagulation function, planned to undergo maxillofacial surgery with NTI were enrolled. Patients were randomly (1:1) assigned to each of the treatment groups: nasal treatment using pure oxybuprocaine gel with adequate lubrication (group G) or 1% ephedrine in addition to oxybuprocaine gel with adequate lubrication (group EG). In addition, the incidence and severity of NTIRE and intubation adjustments were studied.Results: A total of 844 patients, 429 and 415 (groups G and EG, respectively), were included in the analysis. No significant differences were observed in the NTIRE incidence rates in groups G (28%) and EG (27%; p = 0.75, relative risk [RR] = 0.95, 95% confidence interval [CI] 0.70-1.29). No significant differences in the NTIRE incidence rates between the two nostrils were observed in both groups (group G: left, 27.9% vs. right, 28% [p = 0.98, RR = 1.01, 95% CI 0.67-1.51]; group EG: left, 25.8% vs. right, 27.9% [p = 0.63, RR = 1.12, 95% CI 0.72-1.73]. No significant difference was observed in the severity of NTIRE (p = 0.74). In case of difficult advancement of the endotracheal tube, NTIRE incidence was 71% vs. 12% with smooth intubation (p < 0.01,
