“…In patients undergoing endotracheal intubation with cervical immobilization, Hosalli et al [20] showed that channeled laryngoscopes were superior to Macintosh laryngoscopes, with greater ease of intubation and lower impact on hemodynamic variables. In turn, as reported by Çolak et al [21], a minimal cervical motion was obtained during tracheal intubation with the use of Airtraq types of laryngoscope compared with the Macintosh laryngoscope. The advantage of channeled laryngoscopes over Macintosh devices in terms of less movement of the cervical spine was also indicated by Hirabayashi et al [22].…”

INTRODUCTION: The aim of this study was to evaluate intubation performance by paramedics using Macintosh laryngoscope and VieScope ® laryngoscope under simulated difficult airway conditions. METHODS: In a randomized, single-blinded, cross-over simulation trial, 42 paramedics performed endotracheal intubation using VieScope ® and Macintosh (MAC) laryngoscopes in two difficult airway scenarios: (A) tongue edema, (B) manual cervical inline stabilization. The order of participants and intubation methods was random. Time to ventilation constituted the primary outcome, and the secondary outcomes were the success rate of first intubation attempt, overall intubation success rate, Cormack and Lehane grade, and ease of use. RESULTS: In scenario A, the median overall intubation time was 55s (46-109) in the MAC group and 30.5s (26-35) in the VieScope ® group (p < 0.001). The efficacy of the first intubation attempt with MAC and VieScope ® varied and amounted to 64.3% vs. 95.2% (p < 0.001). During scenario B, VieScope ® offered better intubation conditions than MAC (p < 0.001), including shorter intubation time, higher first attempt and overall intubation success rates, as well as better glottic view. CONCLUSIONS: In this simulation trial, we found that VieScope ® could be successfully used for intubation in difficult airways by paramedics with little simulation experience with this device. VieScope ® was associated with shorter time and higher success rates of intubation attempt compared with MAC. Nevertheless, we recommend that the performance of VieScope ® and MAC should be further evaluated in the clinical setting to confirm our results.

“…[4] However, in patients with head and neck trauma or suspected instability of the cervical spine, the endotracheal intubation can be challenging for inexperienced persons. [5] To overcome this in recent years video laryngoscopy has been introduced and increasingly used to facilitate endotracheal intubation. [6,7] C-Mac video laryngoscope is a type of video laryngoscope which consists of a standard Macintosh blade with a small camera and a light source at the end of the blade that connects to a video display.…”

Background: Aim: The aim of the present study is to assess and compare the efficacy of Macintosh laryngoscope with C-MAC video laryngoscope in attenuating the hemodynamic stress responses to laryngoscopy and endotracheal intubation. Subjects and Methods: A total of 60 patients of ASA grade I or II who were admitted in the hospital for general anaesthesia were included in the study. The total number of patients was randomly divided into two groups containing 30 patients each. In one of the group the endotracheal intubation was performed using the Macintosh laryngoscope while in the other group the endotracheal intubation was performed using the C-MAC video laryngoscope. After successful completion of the intubation process the various hemodynamic parameters were constantly recorded at regular time interval for any sign of hemodynamic response among the patients post intubation. Results: Hemodynamic parameters such as systolic, diastolic and mean arterial pressures and mean heart rate were found to be significantly higher among the Macintosh laryngoscope group in comparison to the C-MAC group. However, no significant difference was observed in the percentage of oxygen saturation among the two groups. The time taken for glottis view and total time taken for intubation was found to be significantly higher among the patients intubated with Macintosh laryngoscope in comparison to C-MAC laryngoscope. The increase in the total time taken for intubation was significantly found to increase the hemodynamic response among the patients signifying the increased risk of hemodynamic complications among patients intubated with Macintosh laryngoscope. Cormack-Lehane grading was found to be higher among the patients intubated with the Macintosh laryngoscope which might have resulted in the increased intubation time among the patients intubated with Macintosh laryngoscope. The percentage of successful intubation at the first attempt was also found to be higher in the C-MAC laryngoscope group in comparison to the Macintosh group.The percentage of glottis opening (POGO) was found to increase significantly with C-MAC video laryngoscope in comparison to the Macintosh laryngoscope. Conclusion: The study concluded that video guided C-MAC laryngoscope was a better alternative to conventional Macintosh laryngoscope with decreased hemodynamic response and increased successful intubation among the patients.

INTRODUCTION:Despite the introduction of supraglottic devices for ventilation, endotracheal intubation is still a gold standard for airway management in both prehospital and operating theatre conditions. This systematic review and meta-analysis were conducted to investigate the effectiveness and safety of Airtraq vs. Macintosh laryngoscope for endotracheal intubation during general anesthesia. MATERIAL AND METHODS:The current issue of Pubmed, Embase, Cochrane, Web of science, Scopus (from database inception to October 20, 2020) was searched. Randomized controlled trials (RCT) comparing Airtraq and Macintosh laryngoscope were included in this meta-analysis. The primary outcomes were the success rate of first attempt intubation and intubation time. Secondary outcomes were overall intubation success rate, malposition, and adverse events. Review Manager 5.4 software was used to perform the pooled analysis and assess the risk of bias for each eligible RCT. RESULTS:Seventeen studies were included in the review for data extraction. First attempt success rate was 85.6% for ATQ vs. 68.4% for MAC (OR = 3.00; 95% CI: 1.37, 6.60; p = 0.006; I 2 = 63%). The use of ATQ and MAC for intubation in cervical spine immobilization was associated with the effectiveness of the first intubation attempt at 98.6% vs. 71.1% (OR = 16.40; 95% CI: 3.55, 78.87; p < 0.001; I 2 = 0%). Intubation time with ATQ was shorter than with MAC (MD = -3.19; 95% CI: -9.33, 2.95; p = 0.31; I 2 = 97%). The endotracheal intubation during cervical spinal intubation was associated with significantly shorter procedure duration for ATQ than for MAC (MD = -10.30; 95% CI: -18.43, -2.18; p = 0.01; I 2 = 74%). The total efficacy of intubation, which for ATQ and MAC varied and was 86.7% vs. 80.6% respectively (OR = 2.88; 95% CI: 1.61, 5.13; p < 0.001; I 2 = 0%). CONCLUSIONS:Based on the results of this analysis, we conclude that ATQ can reduce the failed first intubation attempt, especially in cervical manual inline stabilization patients, and reduces the time needed to obtain airway management, but does not provide significant benefits on other adverse events associated
