Objective Tracheal intubation using a direct laryngoscope is difficult to teach. The McGrath videolaryngoscope, a Macintosh-like device with a camera, can be used as a direct laryngoscope to educate novices under supervision using the screen. We compared the effect on Macintosh laryngoscopy skills following training with a McGrath videolaryngoscope as a direct versus indirect laryngoscope. Methods Thirty-seven participants were randomized into direct and indirect groups according to the training method using a McGrath videolaryngoscope. Participants attempted Macintosh direct laryngoscopy in normal and difficult airway scenarios. The primary endpoint was the intubation time, and the rate of successful intubation, dental trauma, and difficulty were secondary outcomes. Results The intubation time after education decreased significantly in both groups and was significantly shorter in the direct group than in the indirect group across time. The difficulty degree in the direct group was lower than that in the indirect group across time; however, the rate of dental trauma was not significantly different. Conclusion Both direct and indirect laryngoscopy using a McGrath videolaryngoscope improved the performance of Macintosh direct laryngoscopy in novices, while direct laryngoscopy using a McGrath videolaryngoscope demonstrated better educational effects than indirect laryngoscopy.

Objective: In obstetric patients’ airway, guidelines have recommended the availability of advanced airway equipment. Our aim was to compare the larynx visualization provided by the Macintosh direct laryngoscope and McGrath video laryngoscope and the intubation time of patients undergoing cesarean section. Methods: This study was conducted at a private obstetrics and gynecology hospital during one month between June and July 2018. A hundred patients scheduled for elective cesarean section under general anesthesia were randomized into two different group’s as intubated using either McGrath VL or Macintosh DL. The intubation times, Cormack–Lehane grade, percentage of glottic opening, mean arterial blood pressure, and heart rates before and after intubation were compared among the groups. Results: The McGrath VL significantly reduced the intubation time compared to the Macintosh DL. In the McGrath VL group, better glottic view set the time of tracheal intubation as assessed using the Cormack-Lehane classification system and POGO scores were recorded. After intubation, hemodynamic parameters were significantly higher in the Macintosh DL group than in the McGrath VL group. Conclusion: The McGrath VL significantly lowered intubation time relative to the Macintosh DL, which may be a critical finding considering the importance of maintaining the mother’s airway for the health of both mother and baby.

Purpose: To compare the efficacy of a low-cost custom-made universal serial bus (USB) endoscope laryngoscope for intubation with a direct laryngoscope and a high-cost video laryngoscope in a mannequin study. Methods: We used one intubation simulator model (mannequin) in our study. A USB endoscope was mounted to the direct laryngoscope as a custom-made USB endoscope laryngoscope (USB-L). We used a video laryngoscope (Glidescope®, Verathon, USA) and a direct laryngoscope (Macintosh) for comparison. Intubation time and the correct placement of the tube were measured. Intubations were performed by two operators and results were compared. Results: We found a statistically significant difference between the video and direct laryngoscope groups (p < 0.001), as well as between the USB-L and direct laryngoscope groups (p = 0.001) for Operator 1. For Operator 2, there was a statistically significant difference between the video laryngoscope group and the direct laryngoscope group (p = 0.022); however, we did not find a significant difference between the USB-L group and the direct laryngoscope group (p = 0.154). Furthermore, there were no significant differences between the USB-L and video laryngoscope groups for either operator (p=0.347 for Operator 1 and p>0.999 for Operator 2). Conclusion: Our study showed that USB endoscope laryngoscope provided similar intubation time to video laryngoscopy at a fraction of the cost; and both had superior times in comparison with direct laryngoscopy.

Abstract OBJECTIVES Controlled reoxygenation on starting cardiopulmonary bypass (CPB) rather than hyperoxic CPB may confer clinical advantages during surgery for congenital cyanotic heart disease. METHODS A single-centre, randomized controlled trial was carried out to compare the effectiveness of controlled reoxygenation (normoxia) versus hyperoxic CPB in children with congenital cyanotic heart disease undergoing open-heart surgery (Oxic-2). The co-primary clinical outcomes were duration of inotropic support, intubation time and postoperative intensive care unit (ICU) and hospital stay. Analysis of the primary outcomes included data from a previous trial (Oxic-1) conducted to the same protocol. RESULTS Ninety participants were recruited to Oxic-2 and 79 were recruited to the previous Oxic-1 trial. There were no significant differences between the groups for any of the co-primary outcomes: inotrope duration geometric mean ratio (normoxia/hyperoxic) 0.97, 95% confidence interval (CI) (0.69–1.37), P-value = 0.87; intubation time hazard ratio (HR) 1.03, 95% CI (0.74–1.42), P-value = 0.87; postoperative ICU stay HR 1.14 95% CI (0.77–1.67), P-value = 0.52, hospital stay HR 0.90, 95% CI (0.65–1.25), P-value = 0.53. Lower oxygen levels were successfully achieved during the operative period in the normoxic group. Serum creatinine levels were lower in the normoxic group at day 2, but not on days 1, 3–5. Childhood developmental outcomes were similar. In the year following surgery, 85 serious adverse events were reported (51 normoxic group and 34 hyperoxic group). CONCLUSIONS Controlled reoxygenation (normoxic) CPB is safe but with no evidence of a clinical advantage over hyperoxic CPB.
