“…The incidence was far lower than that in this study (27.5%; 232/844) and much lower than in almost all similar studies. 18,19 One of the possible reasons for the difference is that tubes with internal diameters of 6.5 and 6.0 mm were used for male and female patients, respectively, which were smaller than those used in this study. In this study, the incidence rate of NTIRE was 27.5% (232/844), similar to that in two other studies.…”

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,

Videolaryngoscopes (VLs) have emerged as a safety net offering several advantages over direct laryngoscopy (DL). The aim of this study is to expand on our previous study conducted in 2016, to deduce which VL is most preferred by clinicians and to highlight any changes that may have occurred over the past 7 years. An extensive systematic literature review was performed on Medline, Embase, Web of Science, and Cochrane Central Database of Controlled Studies for articles published between September 2016 and January 2023. This review highlighted similar results to our study in 2016, with the CMAC being the most preferred for non-channelled laryngoscopes, closely followed by the GlideScope. For channelled videolaryngoscopes, the Pentax AWS was the most clinically preferred. This review also highlighted that there are minimal studies that compare the most-used VLs, and thus we suggest that future studies directly compare the most-used and -preferred VLs as well as the specific nature of blades to attain more useful results.

A Comparison of McGrath Videolaryngoscope versus Macintosh Laryngoscope for Nasotracheal Intubation: A Systematic Review and Meta-Analysis

Background: In this study, it was shown that the routine use of McGrath videolaryngoscopy may improve intubation success rates. The benefits to using a videolaryngoscope in nasotracheal intubation were also demonstrated. However, no solid evidence concerning the effectiveness of the use of McGrath videolaryngoscopes in nasotracheal intubation has previously been reported. As a result, we questioned whether, in adult patients who underwent oral and maxillofacial surgeries with nasotracheal intubation (P), the use of a McGrath videolaryngoscope (I) compared with a Macintosh laryngoscope (C) could reduce the intubation time, improve glottis visualization to a score of classification 1 in the Cormack–Lehane classification system, and improve the first-attempt success rate (O). The secondary outcomes measured were the rate of the use of Magill forceps and the external laryngeal pressure (BURP) maneuver used. Methods: An extensive literature search was conducted using databases. Only randomized controlled trials that compared the McGrath videolaryngoscopy and Macintosh laryngoscopy techniques in nasotracheal intubation in adult patients were included. Results: Five articles met the inclusion criteria and were included in the final analysis (n = 331 patients). The results showed a significant decrease in intubation time and a higher rate of classification 1 scores in the Cormack–Lehane classification system, but no difference in the first-attempt success rates were found between the McGrath group and the Macintosh group. Decreases in the rate of the use of Magill forceps and the use of the external laryngeal pressure maneuver were also found in the pooled analysis. With regard to the overall risk of bias, the selected trials were classified to have at least a moderate risk of bias, because none of the trials could blind the operator to the type of laryngoscope used. Conclusions: Our analysis suggests that the use of a McGrath videolaryngoscope in nasotracheal intubation resulted in shorter intubation times, improved views of the glottis and similar first-success rates in adult patients who received general anesthesia for dental, oral, maxillofacial, or head and neck cancer surgery, and also reduced the use of Magill forceps and the BURP maneuver.
