OBJECTIVE: To determine the incidence of subglottic stenosis (SGS) in children after tracheostomy and identify risk factors for development.
METHODS: Retrospective cohort.
METHODS: All patients (<18 years) undergoing tracheostomy at a tertiary children\'s hospital between 2015 and 2020 were included. Patients with a direct laryngoscopy (DL) concurrent with tracheostomy and a subsequent DL were included. Medical records, including operative reports, were reviewed to identify subglottic stenosis and associated risk factors.
RESULTS: A total of 140 patients were included with mean age at tracheostomy of 2.4 years (standard deviation [SD]: 4.3) (median: 0.5 years, interquartile range [IQR]: 0.3-1.5 years) and gestational age of 33.8 weeks (SD: 5.9) (median: 36 weeks, IQR: 28-39 weeks). At initial DL, 24% (N = 34) had subglottic injury and 26% (N = 37) developed SGS. The incidence of SGS after tracheostomy was 11.5 cases per 100 patients per year. At tracheostomy, lower birth weight (1.8 vs. 2.3 kg, p = 0.005), shorter gestational age (31.8 vs. 34.6 weeks, p = 0.01), younger age (0.8 vs. 2.9 years, p = 0.01), lower weight (5.8 vs. 14.7 kg, p = 0.01), and subglottic injury (44% vs. 21%, p = 0.01) were associated with the development of SGS. Multivariable logistic regression analysis associated birth weight (odds ratio [OR]: 0.49, 95% confidence interval [CI]: 0.31-0.75, p = 0.001) and early subglottic injury (OR: 3.22, 95% CI: 1.31-7.88, p = 0.01) with SGS development.
CONCLUSIONS: The incidence of SGS after pediatric tracheostomy is estimated at 11.5 cases per 100 patients per year. Low birth weight and subglottic injury at the time of tracheostomy were associated with SGS in this vulnerable population of children.
METHODS: 3 Laryngoscope, 2024.

UNASSIGNED: The objective of this study is to compare bed-up-head-elevated (BUHE) position with supine sniffing position (SSP) in patients undergoing rapid sequence intubation (RSI) using direct laryngoscopy in the emergency department (ED).
UNASSIGNED: This single-center randomized controlled superiority trial was carried out from September 2021 to December 2022 in an academic emergency medicine department. The patients undergoing RSI in ED were grouped into two arms, namely BUHE position and SSP. The primary outcome was the time taken for endotracheal intubation. The secondary outcomes were the first-pass success rates and postintubation complications.
UNASSIGNED: A total of 136 patients were enrolled in the study. Time for intubation in the BUHE group was no different from SSP (32.09 s [interquartile range (IQR): 23.30-42.68] vs. 33.40 [IQR: 27.53-45.90], P = 0.17). There was a modest reduction in intubation time when performed by trained experts (22.5 s [IQR: 17.7-25.3] versus 30.3 s [IQR: 21.3-33.2], P = 0.04). The first-attempt success rate in the BUHE position was also similar to the SSP position ([91.18% vs. 90.91%] P = 0.958). Postintubation complications were lesser in BUHE compared to the SSP group ([7.4% vs. 19.7%] P = 0.04).
UNASSIGNED: In our study, BUHE position did not improve time to intubation and first-pass success rate in ED patients compared to SSP. A modest decrease in intubation time was noted while experts used the BUHE position. The postintubation complications were slightly lesser in the BUHE group.

Objective: Pyriform fossa (PF) branchial apparatus anomalies (PFBAA) are rare congenital third or fourth branchial apparatus anomalies (TBAA or FBAA). This article summarizes our paradigm in managing this condition by combining endoscopic procedures and open neck surgery. Methods: A retrospective review was undertaken concerning PFBAA cases treated at our tertiary medical institution between July 2020 and November 2023. Data were collected from case records. Three sequential steps were implemented: (1) direct laryngoscopy to identify internal orifice (IO), with injection of methylene blue into it; (2) open neck surgery to resect all inflammatory tissues, focusing on the ligation of the sinus tract out of PF; and (3) plasma coblation of IO mucosa. Results: In total, 7 cases (4 men and 3 women) were included (28-67 years old, median age 53). Presenting symptoms were various, with 6 lesions on the left and 1 on the right side. Preoperative (PO) fiberoptic laryngoscopy identified IO in 6 patients, while PO barium esophageal study identified outflow from PF in 4 patients. A preliminary diagnosis of PFBAA could be established in all cases (2 TBAA and 5 FBAA cases). Direct laryngoscopy after general anesthesia identified IO in all cases (2 on the base of PF and 5 on the apex of PF). All the surgical procedures were successful, with uneventful recovery in all the patients. No postoperative complications were observed. All the patients resumed oral fluid intake after confirmation of no pharyngeal fistula by barium esophageal study on the seventh postoperative day. The duration of follow-up was between 6 and 40 months (with a median duration of 27 months). No recurrence was observed. Conclusion: Open neck surgery, assisted by endoscopic dyeing of sinus tracts and plasma coblation of IO mucosa, is a suitable treatment for PFBAA in adults. This paradigm is effective and safe for senior surgeons.

Endotracheal intubation is a common lifesaving procedure that often is performed outside the operating room in a variety of clinical scenarios. Providers who perform intubation outside the operating room have variable degrees of training, skill development, and experience. A large number of studies were published in 2023 on the topic of intubations outside the operating room across a wide variety of settings and patient populations. Here, we review relevant papers on this topic published in 2023.

BACKGROUND: Pediatric airway management requires careful clinical evaluation and experienced execution due to anatomical, physiological, and developmental considerations. Video laryngoscopy in pediatric airways is a developing area of research, with recent data suggesting that video laryngoscopes are better than standard Macintosh blades. Specifically, there is a paucity of literature on the advantages of the C-MAC D-blade compared to the McCoy direct laryngoscope.
METHODS: After Ethics Committee approval, 70 American Society of Anesthesiologists physical status 1 and 2 children aged 4-12 years scheduled for elective surgery under general anesthesia were recruited. Patients were randomly allocated to intubation using a C-MAC video laryngoscope size 2 D-blade (Group 1) and a McCoy laryngoscope size 2 blade (Group 2). The Intubation Difficulty Scale (IDS) for ease of intubation was the primary outcome, while Cormack-Lehane grades, duration of laryngoscopy and intubation, hemodynamic responses, and incidence of any airway complications were secondary outcomes.
RESULTS: Both groups were comparable in terms of patient characteristics. The median (IQR) Intubation Difficulty Scale (IDS) score was better but was statistically nonsignificant with C-MAC (0 [0-0] vs. 0 [0-2], p = .055). The glottic views were superior (CL grade I in 32/35 vs. 23/35, p = .002), and the time to best glottic view (6 s [5-7] vs. 8.0 s [6-10], p = .006) was lesser in the C-MAC D-blade group while the total duration of intubation was comparable (20 s [16-22] vs. 18 s [15-22], p = .374). All the patients could be successfully intubated on the first attempt. None of the patients had any complications.
CONCLUSIONS: The C-MAC video laryngoscope size 2 D-blade provided faster and better glottic visualization but similar intubation difficulty compared to McCoy size 2 laryngoscope in children. The shorter time to achieve glottic view demonstrated with the C-MAC failed to translate into a shorter total duration of intubation when compared to the McCoy laryngoscope attributable to a pronounced curvature of the D-blade.

Simulation for airway management allows for acquaintance with new devices and techniques. Endotracheal intubation (ETI), most commonly performed with direct laryngoscopy (DL) or video laryngoscopy (VLS), can be achieved also with combined laryngo-bronchoscopy intubation (CLBI). Finally, an articulating video stylet (ProVu) has been recently introduced. A single-center observational cross-sectional study was performed in a normal simulated airway scenario comparing DL, VLS-Glidescope, VLS-McGrath, CLBI and ProVu regarding the success rate (SR) and corrected time-to-intubation (cTTI, which accounts for the SR). Up to three attempts/device were allowed (maximum of 60 s each). Forty-two consultants with no experience with ProVu participated (15 ± 9 years after training completion). The DL was significantly faster (cTTI) than all other devices (p = 0.033 vs. VLSs, and p < 0.001 for CLBI and Provu), no differences were seen between the two VLSs (p = 0.775), and the VLSs were faster than CLBI and ProVu. Provu had a faster cTTI than CLBI (p = 0.004). The DL and VLSs showed similar SRs, and all the laryngoscopes had a higher SR than CLBI and ProVu at the first attempt. However, by the third attempt, the SR was not different between the DL/VLSs and ProVu (p = 0.241/p = 0.616); ProVu was superior to CLBI (p = 0.038). In consultants with no prior experience, ProVu shows encouraging results compared to DL/VLSs under simulated normal airway circumstances and further studies are warranted.

Direct laryngoscopy (DL) is a modality commonly used in endotracheal intubation (EI). Video laryngoscopy (VL) was introduced to further facilitate the procedure with enhancement in glottic views, which captures the video image of the vocal cords to be projected onto a screen, providing enhanced visualization. This real-time video projection aids in accurately placing the endotracheal tube (ETT) through the vocal cords. In emergency and critical care settings, both laryngoscopes are used for intubations. This study assesses the efficacy of both modalities by comparing success rates in first-attempt tracheal intubation in critically ill patients.  PubMed, EMBASE, and Scopus were searched and all randomized controlled trials (RCTs) and observational studies until 2023 were included. Studies included patients in critical care settings undergoing EI under the guidance of either DL or VL. The primary outcome was the first attempt at successful tracheal intubation. The secondary outcomes assessed the comparative safety of DL and VL by comparing the rates of severe hypoxemia, severe hypotension, and cardiac arrest occurring during each modality. P-values were considered of statistical significance if below 0.05. Statistical analysis was performed using RevMan v5.4 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). The results were displayed in the form of forest plots.  A total of eight studies were included with a total of 5348 patients, with 1780 in the DL group and 3568 in the VL group. Analysis revealed that in emergency situations, the success rate of intubation on the first attempt was significantly higher for VL than DL [81.5% vs 68%; RR= 1.19; 95% CI: 1.10, 1.29; p <0.00001; I2=70%]. There was no significant correlation between VL and severe hypoxemia [13.4% vs 11.6%; RR= 0.99; 95% CI: 0.74, 1.33; p =0.97; I2=46%], severe hypotension [6.09% vs 4.78%; RR:1.19; 95% CI: 0.83, 1.72; p =0.35, I2-15%], and cardiac arrest, [0.8% vs 0.4%; RR= 1.17; 95% CI: 0.37, 3.70]; p =0.79; I2=0%]. Our meta-analysis confirmed that VL has a higher success rate for first-pass intubation than DL. Furthermore, our analysis has shown no significant evidence linking VL to any adverse events.

Background and Objective: Placing the laryngoscope blade directly under the epiglottis (known as the direct view (DV) method) during videolaryngoscopy offers a superior view of the glottis when compared to the indirect method of lifting the epiglottis by positioning the Macintosh blade tip over the vallecula. While there are few studies comparing glottic views using Miller and Macintosh blades in pediatric patients, we have not come across such a study in adults. In this study, we aimed to compare the effectiveness and hemodynamic responses of the Miller laryngoscope and the McGrath-MAC videolaryngoscope (VL) in visualizing the glottic opening using the DV method. Material and Methods: A prospective study was conducted between August and December 2022 at XXX Hospital on 85 patients scheduled for surgical procedures involving endotracheal intubation. Patients were divided into two groups: Miller laryngoscope (Group M) and McGrath-MAC videolaryngoscope (Group VL) and intubated using the direct lifting method of the epiglottis. Hemodynamic responses before and after induction, as well as during laryngoscopy, intubation time, number of attempts, Cormack and Lehane (C&L) score, percentage of glottic opening (POGO), duration of the view of the opening, and need for external laryngeal pressure during intubation were recorded. Results: Both laryngoscopes showed similar effectiveness in terms of POGO and C&L score when used with the direct lifting method of the epiglottis. The median POGO values according to the DV method were 80% in Group M and 70% in Group VL (p = 0.099). Hemodynamic responses, intubation time, number of attempts, duration of view of the glottis opening, and the need for external laryngeal pressure were similar between the groups. Conclusions: Due to its ability to provide effective intubation conditions, we believe that the McGrath-MAC VL, when used with the indirect view method, can also be utilized in anesthesia practices alongside the DV method.

UNASSIGNED: For true clean-contaminated head and neck procedures, the literature supports ≤24 hours of perioperative antibiotics. However, there are certain otolaryngology procedures with low surgical site infection (SSI) risk for which there is negligible benefit from antibiotic prophylaxis. The objective of this evaluation was to describe antibiotic use and adherence to evidence-based institutional guidelines in low-risk head and neck procedures.
UNASSIGNED: This was a single-center, retrospective cohort study of patients undergoing low-risk clean-contaminated head and neck procedures wherein antibiotic prophylaxis was not indicated, based on evidence-based institutional guidelines.
UNASSIGNED: Among the 291 included patients, perioperative antibiotics were unnecessarily administered in 29% of patients. Among patients who received antibiotics, 76% received preoperative antibiotics and 41% received postoperative antibiotics, for a median duration of 7 days. There were no significant differences in SSIs, mortality, and length of stay for those receiving perioperative antibiotics versus those not receiving perioperative antibiotics.
UNASSIGNED: These data highlight the need for antibiotic stewardship interventions and partnerships between antibiotic stewardship teams and surgical services.
