Introduction: McGrath® MAC videolaryngoscope is a single-handed device designed to facilitate intubation in patients both in patients with normal airway conditions (without any complications) or airway conditions with complications such as cervical spine and/or anatomic abnormalities. Objective: This study aims to compare McGrath® MAC videolaryngoscope and direct laryngoscope using Macintosh blades as learning material or study simulators for medical personnel (including anesthesiologist and paramedics) and novice operator (medical students). Method: this study is a systematic review using the PRISMA method which was carried out systematically. Data was collected through Pubmed, direct science, EBSCOHost, and Proquest using the keywords ‘airway management ', ‘laryngoscopy', and 'manikin'. Journal included based on published publication time between 2008 and 2020, a study using SimMan Laerdal Airway manikin, a journal discussing intubation using McGrath® MAC videolaryngoscope and direct laryngoscope with Macintosh blades here, where it is normal airway (without complications) and difficult airway. Results: 1556 journals were collected through 4 journal search sites and then carried out a screening process for the publication year approved in 2008 to 2020. Four studies use adult manikin SimMan Laerdal Airway including 247 participants were included in this systematic review. Conclusion: Based on journals that have been reviewed, McGrath® MAC videolaryngoscope provides better and superior results compared to Macintosh in terms of the success rate and visualization of glottis. Also, the intubation time using McGrath® MAC videolaryngoscope is shorten compared to Macintosh both on the normal airway (without complication) and difficult airway. The participants (medical personnel and novice operators) in all studies that reviewed prefer to use McGrath® Mac videolaryngoscope instead of using direct laryngoscope with Macintosh blade for Endotracheal Intubation mainly used for learning or study simulators.

Introduction Early endotracheal intubation improves neurological outcomes in cardiopulmonary resuscitation, although cardiopulmonary resuscitation is initially carried out by personnel with limited experience in a significant proportion of cases. Videolaryngoscopes might decrease the number of attempts and time needed, especially among novices. We sought to compare videolaryngoscopes with direct laryngoscopes in simulated cardiopulmonary resuscitation scenarios. Materials and methods Forty-four medical students were recruited to serve as novice users. Following brief, standardized training, students executed endotracheal intubation with the King Vision®, Macintosh and VividTrac® laryngoscopes, on a cardiopulmonary resuscitation trainer in normal and difficult airway scenarios. We evaluated the time to and proportion of successful intubation, the best view of the glottis, esophageal intubation, dental trauma and user satisfaction. Results In the normal airway scenario, significantly shorter intubation times were achieved using the King Vision® than the Macintosh laryngoscope. In the difficult airway scenario, we found that the VividTrac® was superior to the King Vision® and Macintosh laryngoscopes in the laryngoscopy time. In both scenarios, we noted no difference in the first-attempt success rate, but the best view of the glottis and dental trauma, esophageal intubation and bougie use were more frequent with the Macintosh laryngoscope than with the videolaryngoscopes. The shortest tube insertion times were achieved using the King Vision® in both scenarios. Conclusion All providers achieved successful intubation within three attempts, but we found no device superior in any of our scenarios regarding the first-attempt success rate. The King Vision® was superior to the Macintosh laryngoscope in the intubation time in the normal airway scenario and noninferior in the difficult airway scenario for novice users. We noted significantly less esophageal intubation using the videolaryngoscopes than using the Macintosh laryngoscope in both scenarios. Based on our results, the KingVision® might be recommended over the VividTrac® and Macintosh laryngoscopes for further evaluation.

Abstract Purpose The aim of this study was to compare the rate of first attempt success of endotracheal intubation performed by ambulance nurses in patients with a Glasgow Coma Scale (GCS)  of 3 using video laryngoscopy versus direct laryngoscopy. Methods A prospective cohort study was conducted in a single, independent ambulance service. Twenty of a total of 65 nurse-staffed ambulances were equipped with a video laryngoscope; a classic direct laryngoscope (Macintosh) was available on all 65 ambulances. The primary outcome was first attempt success of the intubation. Secondary outcomes were overall success, time needed for intubation, adverse events, technical or environmental issues encountered, and return of spontaneous circulation (ROSC). Ambulance nurses were asked if the intubation device had affected the outcome of the intubation. Results The first attempt success rate in the video laryngoscopy group [53 of 93 attempts (57%)] did not differ from that in the direct laryngoscopy group [61 of 126 (48%); p = 0.221]. However, the second attempt success rate was higher in the video laryngoscopy group [77/93 (83%) versus 80/126 (63%), p = 0.002]. The median time needed for the intubation (53 versus 56 s) was similar in both groups. Ambulance nurses more often expected a positive effect when performing endotracheal intubation with a video laryngoscope (n = 72, 81%) compared with a direct laryngoscope (n = 49, 52%; p < 0.001). Conclusion Although no significant effect on the first attempt success was found, video laryngoscopy did increase the overall success rate. Ambulance nurses had a more positive valuation of the video laryngoscope with respect to success chances.

Background.Videolaryngoscopes may not be useful in the presence of hematemesis or vomitus. We compared the utility of the Macintosh laryngoscope (McL), which is a direct laryngoscope, with that of the Pentax-AWS Airwayscope (AWS) and McGRATH MAC (McGRATH), which are videolaryngoscopes, in simulated hematemesis and vomitus settings.Methods.Seventeen anesthesiologists with more than 1 year of experience performed tracheal intubation on an adult manikin using McL, AWS, and McGRATH under normal, hematemesis, and vomitus simulations.Results.In the normal setting, the intubation success rate was 100% for all three laryngoscopes. In the hematemesis settings, the intubation success rate differed significantly among the three laryngoscopes (P=0.021). In the vomitus settings, all participants succeeded in tracheal intubation with McL or McGRATH, while five failed in the AWS trial with significant difference (P=0.003). The intubation time did not significantly differ in normal settings, while it was significantly longer in the AWS trial compared to McL or McGRATH trial in the hematemesis or vomitus settings (P<0.001, compared to McL or McGRATH in both settings).Conclusion.The performance of McGRATH and McL can be superior to that of AWS for tracheal intubation in vomitus and hematemesis settings in adults.

ObjectiveWe sought to determine whether the use of Pentax-AWS Airwayscope (AWS) applied less force on oral structures during intubation attempts than a conventional direct laryngoscope (DL).DesignProspective cross-over study.ParticipantsA total of 37 physicians (9 transitional-year residents, 20 emergency medicine residents and 8 emergency physicians) were enrolled.InterventionsWe used four simulation scenarios according to the difficulty of intubation and devices and used a high-fidelity simulator to quantify the forces applied on the oral structures.Outcome measuresPrimary outcomes were the maximum force applied on the maxillary incisors and tongue. Other outcomes of interest were time to intubation and glottic view during intubation attempts.ResultsThe maximum force applied on the maxillary incisors in the normal airway scenario was higher with the use of AWS than that with DL (107 newton (N) vs 77 N, p=0.02). By contrast, the force in the difficult airway scenario was significantly lower with the use of AWS than that of the DL (89 N vs 183 N, p<0.01). Likewise, the force applied on the tongue was significantly lower with the use of AWS than the use of DL in both airway scenarios (11 N vs 27 N, p<0.001 in the normal airway scenario; 12 N vs 40 N, p<0.01 in the difficult airway scenario).ConclusionsThe use of AWS during intubation attempts was associated with decreased forces applied to oral structures in the simulated difficult airway scenario.

Training Background

Objectives: In the prehospital setting, endotracheal intubation (ETI) is sometimes required to secure a patient’s airways. Emergency ETI in the field can be particularly challenging, and success rates differ widely depending on the provider’s training, background, and experience. Our aim was to evaluate the ETI success rate in a resident-staffed and specialist-physician-supervised emergency prehospital system. Methods: This retrospective study was conducted on data extracted from the Geneva University Hospitals’ institutional database. In this city, the prehospital emergency response system has three levels of expertise: the first is an advanced life-support ambulance staffed by two paramedics, the second is a mobile unit staffed by an advanced paramedic and a resident physician, and the third is a senior emergency physician acting as a supervisor, who can be dispatched either as backup for the resident physician or when a regular Mobile Emergency and Resuscitation unit (Service Mobile d’Urgence et de Réanimation, SMUR) is not available. For this study, records of all adult patients taken care of by a second- and/or third-level prehospital medical team between 2008 and 2018 were screened for intubation attempts. The primary outcome was the success rate of the ETI attempts. The secondary outcomes were the number of ETI attempts, the rate of ETI success at the first attempt, and the rate of ETIs performed by a supervisor. Results: A total of 3275 patients were included in the study, 55.1% of whom were in cardiac arrest. The overall ETI success rate was 96.8%, with 74.4% success at the first attempt. Supervisors oversaw 1167 ETI procedures onsite (35.6%) and performed the ETI themselves in only 488 cases (14.9%). Conclusion: A resident-staffed and specialist-physician-supervised urban emergency prehospital system can reach ETI success rates similar to those reported for a specialist-staffed system.

Abstract Background: Patients with COVID-19 may require emergency tracheal intubation for mechanical ventilation by emergency physicians. However, the success rate, complications, operator safety, and issues around personal protective equipment (PPE) and barrier enclosure use are not known in this context.Methods: This was a retrospective study of data for adult patients with COVID-19 who underwent endotracheal intubation performed by emergency physicians at four hospitals in the Tokyo Metropolitan Area between January 2020 and September 2020. Patient characteristics, intubation-related factors, and intubation success and complications rates were obtained. Two analyses were then performed. In analysis 1, the intubation success rate in patients was compared among four groups using different types of PPE. In analysis 2, patients were compared by those intubated with or without barrier enclosure.Results: In total, 46 patients met the inclusion criteria, of whom 85% were successfully intubated at the first attempt, 27% experienced hypotension, and 27% experienced hypoxia. No muscle relaxants were used in 8.7% and the Macintosh blade was used in 37%. The four PPE types and the intubation confirmation methods varied considerably, but all met the WHO recommendations. A barrier enclosure device was used in 26%, with a success rate of approximately 80% irrespective of its use.Conclusions: The success rate at the first attempt of intubation was relatively high, albeit with a moderately high complication rate. All PPE types were safe, including when barrier enclosures were used. Success was not affected by using barrier enclosures.

AbstractObjectiveThe primary goal of this study was to compare paramedic first pass success rate between two different video laryngoscopes and direct laryngoscopy (DL) under simulated prehospital conditions in a cadaveric model.MethodsThis was a non-randomized, group-controlled trial in which five non-embalmed, non-frozen cadavers were intubated under prehospital spinal immobilization conditions using DL and with both the GlideScope Ranger (GL; Verathon Inc, Bothell, Washington USA) and the VividTrac VT-A100 (VT; Vivid Medical, Palo Alto, California USA). Participants had to intubate each cadaver with each of the three devices (DL, GL, or VT) in a randomly assigned order. Paramedics were given 31 seconds for an intubation attempt and a maximum of three attempts per device to successfully intubate each cadaver. Confirmation of successful endotracheal intubation (ETI) was confirmed by one of the six on-site physicians.ResultsSuccessful ETI within three attempts across all devices occurred 99.5% of the time overall and individually 98.5% of the time for VT, 100.0% of the time for GL, and 100.0% of the time for DL. First pass success overall was 64.4%. Individually, first pass success was 60.0% for VT, 68.8% for GL, and 64.5% for DL. A chi-square test revealed no statistically significant difference amongst the three devices for first pass success rates (P=.583). Average time to successful intubation was 42.2 seconds for VT, 38.0 seconds for GL, and 33.7 for seconds for DL. The average number of intubation attempts for each device were as follows: 1.48 for VT, 1.40 for GL, and 1.42 for DL.ConclusionThe was no statistically significant difference in first pass or overall successful ETI rates between DL and video laryngoscopy (VL) with either the GL or VT (adult).HodnickR, ZitekT, GalsterK, JohnsonS, BledsoeB, EbbsD.

Background: Video laryngoscope (VL) has increased the success rate of intubation but the commercial VL is unaffordable for community hospitals. Therefore, Ramathibodi mobile VL (RAMA-mVL) was invented to close the gap and expected that it would be equivalent to the current device and lower price.Objective: To determine the effectiveness of intubation, compare by using RAMA-mVL and McGrath®Methods: The randomized, single-blinded study of the success intubation between RAMA-mVL and McGrath® was conducted in a manikin. Medical personnel with intubation experiences was included and trained before performing the procedure. The success rate for one best shot of intubation, time to intubation, satisfaction, and value between both VL were recorded and analyzedResults: A total of 208 persons entered the research, 104 in each group. The success rate for intubation by using both VL is 100%. The mean of time to intubation using RAMA-mVL was significantly less than that of McGrath®, which were 9.12 (±4.28) and 11.19 (±5.04) seconds, respectively (95% CI 0.001 - 0.9, P = .002). The satisfaction with innovation that is easy to build between RAMA-mVL and McGrath® was 4.88 (±0.32) and 4.23 (±0.96) points (95% CI 0.46 - 0.85, P < .001). Additionally, the cost of RAMA-mVL was cheaper than McGrath®.Conclusions: RAMA-mVL performed equivalent and even better than McGrath® compared by intubation success rate, mean intubation time, satisfaction, and cost-effectiveness.
