Abstrakt: Purpose: Nasotracheal intubation (NTI) is required for surgery in oropharyngeal (OP) carcinoma patients, but it may be challenging because of distorted anatomy, mucosal congestion, and increased risk of bleeding. Flexible bronchoscopy (FB)-guided NTI is preferred in these cases but has limitations. In this randomized controlled study, we sought to compare C-MAC®D-BLADE-guided videolaryngoscopy (VL) (Karl Storz SE & Co. KG, Tuttlingen, Germany) with FB for NTI under general anesthesia in patients with OP carcinomas. Methods: We randomized a total of 100 patients with OP carcinoma and El-Ganzouri’s risk index (EGRI) < 7 to undergo NTI under general anesthesia with FB (n= 50) or C-MAC D-BLADE-guided VL (n= 50). The primary outcome was the total intubation time. We also recorded the time to glottis view, nasal intubation difficulty scale (NIDS) score, best percentage of glottis opening score, and complications. Results: The median [interquartile range (IQR)] total intubation time was shorter with VL than with FB (total intubation time, 38 [26–43] sec vs60 [52–65] sec; difference, −20 sec [95% confidence interval (CI), −27 to −11]; P< 0.001). Similarly, the median [IQR] time to glottis view was shorter with VL compared to FB (8 [6–9] sec vs22 [14–25] sec; difference, −13 sec [95% CI, −17 to −10]; P< 0.001). The median NIDS score was higher with VL (difference, 2 [95% CI, 2 to 3]; P< 0.001). The incidences of airway trauma (two cases with FB vsseven with VL; P= 0.30) and postoperative sore throat (ten cases in both groups; P= 0.56) were similar. Conclusion: Compared to FB, C-MAC D-BLADE-based VL reduced the total time for nasal intubation oropharyngeal carcinoma patients, potentially representing an acceptable alternative in selected cases.
