McGrath MAC Videolaryngoscope Versus Optiscope Video Stylet for Tracheal Intubation in Patients With Manual Inline Cervical Stabilization: A Randomized Trial.
Anesthesia & Analgesia, 2020Co-Authors: Hyun Kyu Yoon, Hyongmin Oh, Jung Bin Park, Hee Pyoung ParkAbstract:BACKGROUND: Manual inline stabilization of the head and neck is a recommended maneuver for tracheal intubation in patients with a suspected cervical injury. However, because applying this maneuver inevitably restricts neck flexion and head extension, indirect intubating devices such as a Videolaryngoscope or a video stylet could be required for successful tracheal intubation. In this study, we compared the clinical performance of the McGrath MAC Videolaryngoscope versus the Optiscope video stylet in patients with manual inline cervical stabilization during tracheal intubation. METHODS: In 367 consecutive patients undergoing elective cervical spine surgery, tracheal intubation was randomly performed with manual inline stabilization using either the McGrath MAC Videolaryngoscope (group M, n = 183) or the Optiscope video stylet (group O, n = 184) by 2 experienced anesthesiologists in a single institution. The primary outcome was the first-attempt success rate of tracheal intubation. Secondary outcomes were intubation time and the incidence of postoperative airway complications, such as sore throat, hoarseness, blood in the oral cavity, and blood staining on the endotracheal tube. RESULTS: The first-attempt success rate of tracheal intubation was significantly higher in group M compared with group O (92.3% vs 81.0%; risk difference [95% confidence interval], 0.11 [0.05-0.18]; P = .002). The intubation time was significantly shorter in group M than in group O (35.7 ± 27.8 vs 49.2 ± 43.8; mean difference [95% confidence interval], 13.50 [5.90-21.10]; P = .001). The incidence of postoperative airway complications was not significantly different between the 2 groups. CONCLUSIONS: The McGrath MAC Videolaryngoscope showed a higher first-attempt success rate for tracheal intubation and a shorter intubation time than the Optiscope video stylet in cervical spine patients with manual inline stabilization during tracheal intubation. These results suggest that the McGrath MAC Videolaryngoscope may be a better option for tracheal intubation in such patients.

cervical spine motion during tracheal intubation using an optiscope versus the mcgrath Videolaryngoscope in patients with simulated cervical immobilization a prospective randomized crossover study
Anesthesia & Analgesia, 2019Co-Authors: Hee Pyoung Park, Jaeyeon Chung, Hyun Kyu YoonAbstract:BACKGROUND: In patients with an unstable cervical spine, maintenance of cervical immobilization during tracheal intubation is important. In McGrath videolaryngoscopic intubation, lifting of the blade to raise the epiglottis is needed to visualize the glottis, but in patients with an unstable cervical spine, this can cause cervical spine movement. By contrast, the Optiscope, a rigid video-stylet, does not require raising of the epiglottis during tracheal intubation. We therefore hypothesized that the Optiscope would produce less cervical spine movement than the McGrath Videolaryngoscope during tracheal intubation. The aim of this study was to compare the Optiscope with the McGrath Videolaryngoscope with respect to cervical spine motion during intubation in patients with simulated cervical immobilization. METHODS: The primary outcome of the study was the extent of cervical spine motion at the occiput-C1, C1-C2, and C2-C5 segments. In this randomized crossover study, the cervical spine angle was measured before and during tracheal intubation using either the Optiscope or the McGrath Videolaryngoscope in 21 patients with simulated cervical immobilization. Cervical spine motion was defined as the change in angle at each cervical segment during tracheal intubation. RESULTS: There was significantly less cervical spine motion at the occiput-C1 segment using the Optiscope rather than the McGrath Videolaryngoscope (mean [98.33% CI]: 4.7° [2.4-7.0] vs 10.4° [8.1-12.7]; mean difference [98.33% CI]: -5.7° [-7.5 to -3.9]). There were also fewer cervical spinal motions at the C1-C2 and C2-C5 segments using the Optiscope (mean difference versus the McGrath Videolaryngoscope [98.33% CI]: -2.4° [-3.7 to -1.2]) and -3.7° [-5.9 to -1.4], respectively). CONCLUSIONS: The Optiscope produces less cervical spine motion than the McGrath Videolaryngoscope during tracheal intubation of patients with simulated cervical immobilization.

postoperative sore throat and subglottic injury after mcgrath mac videolaryngoscopic intubation with versus without a stylet in patients with a high mallampati score a randomized controlled trial
BMC Anesthesiology, 2019Co-Authors: Hyun Kyu Yoon, Hyongmin Oh, Hee Pyoung ParkAbstract:A tracheal tube stylet can be used to assist successful tracheal intubation, especially during videolaryngoscopic intubation because Videolaryngoscopes with a Macintosh-type blade such as McGrath® MAC Videolaryngoscope have more acute angle than conventional Macintosh laryngoscope. However, the use of a stylet during tracheal intubation can raise concerns about stylet-induced postoperative airway complications, such as sore throat, subglottic injury, and hoarseness. In this study, we compared the incidence of postoperative airway complications after McGrath® MAC videolaryngoscopic intubation with versus without a stylet in patients with a high Mallampati score. In 104 patients with Mallampati score III or IV and who were scheduled for lumbar or thoracic spine surgery, McGrath® MAC videolaryngoscopic intubation was performed either with a stylet (group S, n = 52) or without a stylet (group N, n = 52). The primary outcome measure was the incidences of sore throat evaluated at 1 and 24 h postoperatively. Secondary outcome measures were the incidences of subglottic injury and postoperative hoarseness. The incidence of CL grade III in group S and N was 3.8 and 5.8%, respectively. No patient showed CL grade IV. The incidences of sore throat at 1 (26.9 vs 19.2%, P = 0.485) and 24 h (17.3 vs 13.5%, P = 0.786, respectively) postoperatively were not significantly different between the group S and N. However, the incidence of subglottic injury was significantly higher in the group S, compared with the group N (65.4 vs 42.3%, P = 0.030). The incidence of postoperative hoarseness did not differ significantly between the two groups. The use of a stylet during McGrath® MAC videolaryngoscopic intubation did not have a significant impact on the incidence of postoperative sore throat in patients with a high Mallampati score. Avoiding the use of a stylet during intubation with McGrath® MAC Videolaryngoscope may reduce the incidence of subglottic injury in such patients.

comparison of the uescope Videolaryngoscope with the macintosh laryngoscope during simulated cardiopulmonary resuscitation a randomized cross over multi center manikin study
Medicine, 2018Co-Authors: Lukasz Szarpak, Jerzy Robert Ladny, Jacek Smereka, Marcin Madziala, Marek Dabrowski, Agnieszka Madziala, Michael Czekajlo, Alexander Kaserer, Ruslan Yakubtsevich, Kurt RuetzlerAbstract:BACKGROUND: Endotracheal intubation (ETI) can be challenging, especially in life-threatening situations such as cardiopulmonary resuscitation (CPR). Videolaryngoscopes aim to ease ETI, but effort is still widely discussed. This study intended to investigate 2 different airway devices regarding the success rate of ETI during ongoing chest compressions. METHODS: This randomized, cross-over, multi-center manikin trial included 85 experienced paramedics actively working in the emergency medicine service. After a standardized training session, all paramedics underwent 3 airway scenarios using both, direct laryngoscopy using a Macintosh blade and Videolaryngoscope (the UEScope): normal airway without chest compressions, normal airway with uninterrupted chest compressions, and difficult airway with uninterrupted chest compressions. The primary outcome was successful ETI, defined as successful placement of the endotracheal tube within the manikin's trachea. Secondary outcomes were number of intubation attempts, time to successful ETI, time to best glottis view, best percent of glottic opening, best glottic view score (Cormack and Lehane), occurrence of dental trauma, ease of use, and willing to reuse in real-life situations. RESULTS: The UEScope provided a better glottis visualization, and higher first pass intubation success rate compared to direct laryngoscopy in all 3 scenarios. The overall intubation success was higher, and the intubation time was shorter with the UEScope in scenario B and scenario C, but was comparable in scenario A. Dental compression occurred less often using the UEScope and paramedics rated intubation using the UEScope easier compared to direct laryngoscopy in all 3 airway scenarios. CONCLUSION: In simulated CPR scenarios, intubation with the UEScope resulted in a better glottis visualization, a higher intubation success, and a shorter intubation time compared to Macintosh laryngoscope (MAC). Moreover, in situations where the airway is difficult for ETI especially by the paramedic, the UEScope would be a better choice than the MAC. Further studies are needed to confirm these results in real-life patients.

A comparison of McGrath MAC® and standard direct laryngoscopy in simulated immobilized cervical spine pediatric intubation: a manikin study
European Journal of Pediatrics, 2017Co-Authors: Marcin Madziala, Jacek Smereka, Kurt Ruetzler, Marek Dabrowski, Steve Leung, Lukasz SzarpakAbstract:Emergency airway management in children is generally considered to be challenging, and endotracheal intubation requires a high level of personal skills and experience. Immobilization of the cervical spine is indicated in all patients with the risk of any cervical spine injury but significantly aggravates endotracheal intubation. The best airway device in this setting has not been established yet, although the use of Videolaryngoscopes is generally promising. Seventy-five moderately experienced paramedics of the Emergency Medical Service of Poland performed endotracheal intubations in a pediatric manikin in three airway scenarios: (A) normal airway, (B) manual in-line cervical immobilization, and (C) cervical immobilization using a Patriot cervical extrication collar and using two airway techniques: (1) McGrath Videolaryngoscope and (2) Macintosh blade in a randomized sequence. First-attempt intubation success rate, time to intubation, glottis visualization, and subjective ease of intubation were investigated in this study. Intubation of difficult airways, including manual in-line and cervical collar immobilization, using the McGrath was significantly faster, with a higher first-attempt intubation success rate, better glottic visualization, and ease of intubation, compared to Macintosh-guided intubation. In the normal airway, both airway techniques performed equal. Conclusion: Our manikin study indicates that the McGrath may be a reasonable first intubation technique option for endotracheal intubation in difficult pediatric emergencies. Further clinical studies are therefore indicated. What is known : • Airway management in pediatrics is challenging and requires a high level of skills and experience. Cervical immobilization is indicated in all patients with any risk of cervical spine injury, but it significantly aggravates endotracheal intubation in these patients. Videolaryngoscopes have been reported to ease intubation and provide better airway visualization in the regular clinical setting. What is new: • The McGrath is an easy-to-use and clinically often used Videolaryngoscope, but it has never been investigated in pediatrics with an immobilized cervical spine. In the normal airway, the McGrath provided better airway visualization compared to Macintosh laryngoscopy. However, better visualization did not lead to decreased time to intubation and a higher success rate of the first intubation attempt. In difficult airways, the McGrath provided better airway visualization and this led to faster intubation, a higher first-attempt intubation success rate, and better ease of intubation compared to Macintosh-guided intubation.

c mac Videolaryngoscope compared with direct laryngoscopy for rapid sequence intubation in an emergency department a randomised clinical trial
European Journal of Anaesthesiology, 2016Co-Authors: Simon Sulser, Martin Schlaepfer, Dirk Ubmann, Martin Brueesch, Georg Goliasch, Burkhardt Seifert, Donat R Spahn, Kurt RuetzlerAbstract:Airway management in the emergency room can be challenging when patients suffer from life-threatening conditions. Mental stress, ignorance of the patient's medical history, potential cervical injury or immobilisation and the presence of vomit and/or blood may also contribute to a difficult airway. Videolaryngoscopes have been introduced into clinical practice to visualise the airway and ultimately increase the success rate of airway management. The aim of this study was to test the hypothesis that the C-MAC Videolaryngoscope improves first-attempt intubation success rate compared with direct laryngoscopy in patients undergoing emergency rapid sequence intubation in the emergency room setting. A randomised clinical trial. Emergency Department of the University Hospital, Zurich, Switzerland. With approval of the local ethics committee, we prospectively enrolled 150 patients between 18 and 99 years of age requiring emergency rapid sequence intubation in the emergency room of the University Hospital Zurich. Patients were randomised (1 : 1) to undergo tracheal intubation using the C-MAC Videolaryngoscope or by direct laryngoscopy. Owing to ethical considerations, patients who had sustained maxillo-facial trauma, immobilised cervical spine, known difficult airway or ongoing cardiopulmonary resuscitation were excluded from our study. All intubations were performed by one of three very experienced anaesthesia consultants. First-attempt success rate served as our primary outcome parameter. Secondary outcome parameters were time to intubation; total number of intubation attempts; Cormack and Lehane score; inadvertent oesophageal intubation; ease of intubation; complications including violations of the teeth, injury/bleeding of the larynx/pharynx and aspiration/regurgitation of gastric contents; necessity of using further alternative airway devices for successful intubation; maximum decrease of oxygen saturation and technical problems with the device. A total of 150 patients were enrolled, but three patients had to be excluded from the analysis, resulting in 74 patients in the C-MAC videolaryngoscopy group and 73 patients in the direct laryngoscopy group. Tracheal intubation was achieved successfully at the first attempt in 73 of 74 patients in the C-MAC group and all patients in the direct laryngoscopy group (P = 1.0). Time to intubation was similar (32 ± 11 vs. 31 ± 9 s, P = 0.51) in both groups. Visualisation of the vocal cords, represented as the Cormack and Lehane score, was significantly better using the C-MAC Videolaryngoscope (P < 0.001). Our study demonstrates that visualisation of the vocal cords was improved by using the C-MAC Videolaryngoscope compared with direct laryngoscopy. Better visualisation did not improve first-attempt success rate, which in turn was probably based on the high level of experience of the participating anaesthesia consultants.

the c mac Videolaryngoscope compared with conventional laryngoscopy for rapid sequence intubation at the emergency department study protocol
Scandinavian Journal of Trauma Resuscitation and Emergency Medicine, 2015Co-Authors: Simon Sulser, Dirk Ubmann, Martin Brueesch, Georg Goliasch, Burkhardt Seifert, Donat R Spahn, Kurt RuetzlerAbstract:Especially in the emergency setting, rapid and successful airway management is of major importance. Conventional endotracheal intubation is challenging and requires high level of individual skills and experience. Videolaryngoscopes like the C-MAC are likely to offer better glottis visualization and serve as alternatives to conventional endotracheal intubation. The aim of this study is to compare clinical performance and feasibility of the C-MAC Videolaryngoscope compared to conventional endotracheal intubation in the emergency setting. This study is designed as a prospective, patient-blinded, mono-center, randomized cohort study. This study will be performed at the Emergency Department of the University Hospital Zurich, Zurich, Switzerland. All patients transferred to the Emergency Department and requiring emergent endotracheal intubation will be screened. Successful intubation with first intubation attempt will serve as the primary outcome. Time to intubation, intubation attempts, Cormack & Lehane Score, ease of intubation, complications, necessity of using alternate intubation device, maximum drop of saturation, and potential technical problems serve as secondary outcomes. In the clinical setting, the ultimate success rate of endotracheal intubation ranges between 97% and 99%. Unexpected difficulties during laryngoscopy and poor glottis visualization occur in up to 9% of all cases. In these cases, Videolaryngoscopes may increase success rate of initial intubation attempt and thereby patient safety. www.clinicaltrials.gov (identifier NCT02297113 ).

mcgrath mac Videolaryngoscope versus macintosh laryngoscope for orotracheal intubation in intensive care patients the randomised multicentre macman trial study protocol
BMJ Open, 2015Co-Authors: Arthur Bailly, Jean Baptiste Lascarrou, Aurelie Le Thuaut, Julie Boisramehelms, Toufik Kamel, Emmanuelle Mercier, Jean Damien Ricard, Virginie Lemiale, Benoit Champigneulle, Jean ReignierAbstract:Introduction Critically ill patients with acute respiratory, neurological or cardiovascular failure requiring invasive mechanical ventilation are at high risk of difficult intubation and have organ dysfunctions associated with complications of intubation and anaesthesia such as hypotension and hypoxaemia. The complication rate increases with the number of intubation attempts. Videolaryngoscopy improves elective endotracheal intubation. McGRATH MAC is the lightest Videolaryngoscope and the most similar to the Macintosh laryngoscope. The primary goal of this trial was to determine whether videolaryngoscopy increased the frequency of successful first-pass intubation in critically ill patients, compared to direct view Macintosh laryngoscopy. Methods and analysis MACMAN is a multicentre, open-label, randomised controlled superiority trial. Consecutive patients requiring intubation are randomly allocated to either the McGRATH MAC Videolaryngoscope or the Macintosh laryngoscope, with stratification by centre and operator experience. The expected frequency of successful first-pass intubation is 65% in the Macintosh group and 80% in the Videolaryngoscope group. With α set at 5%, to achieve 90% power for detecting this difference, 185 patients are needed in each group (370 in all). The primary outcome is the proportion of patients with successful first-pass orotracheal intubation, compared between the two groups using a generalised mixed model to take the stratification factors into account. Ethics and dissemination The study project has been approved by the appropriate ethics committee (CPP Ouest 2, # 2014-A00674-43). Informed consent is not required, as both laryngoscopy methods are considered standard care in France; information is provided before study inclusion. If videolaryngoscopy proves superior to Macintosh laryngoscopy, its use will become standard practice, thereby decreasing first-pass intubation failure rates and, potentially, the frequency of intubation-related complications. Thus, patient safety should benefit. Further studies would be warranted to determine whether videolaryngoscopy is also beneficial in the emergency room and for prehospital emergency care.

comparison of the magill forceps and the boedeker curved intubation forceps for removal of a foreign body in a manikin
Journal of Clinical Anesthesia, 2012Co-Authors: Ben H Boedeker, Mary A Bernhagen, David J Miller, John D DoyleAbstract:Abstract Study Objective To compare the straight Magill and the curved Boedeker Intubation Forceps in foreign body removal in a manikin with a difficult airway using the Videolaryngoscope. Design Prospective comparative study. Setting University Medical Center. Subjects 17 medical providers, 16 anesthesia staff, and one respiratory therapist. Measurements The observed Cormack-Lehane (CL) glottic view and success/failure of the removal attempts were recorded. Main Results The CL scores obtained using the Magill and Boedeker forceps were not significantly different ( P = 0.3984). However, the differences in success rates for removal of the foreign object using standard (0 = success, 17=failure) and Boedeker forceps (0 = failure, 17=success) were strongly significant ( P Conclusion The curve of the Boedeker Intubation Forceps allows both the tip of the forceps and the glottic opening to be simultaneously visible in the field of view during videolaryngoscopy, making removal of glottic foreign bodies easier.

endotracheal intubation in a medical transport helicopter comparing direct laryngoscopy with the prototype storz cmac Videolaryngoscope in a simulated difficult intubating position
Studies in health technology and informatics, 2009Co-Authors: Ben H Boedeker, Mary A Bernhagen, Benjamin W Berg, Bosseau W MurrayAbstract:: This pilot study examined backward intubation of the Laerdal Difficult Airway Manikin in a medical transport helicopter using the prototype (a new more compact) Storz CMAC Videolaryngoscope. The standard manikin airway Cormack Lehane (CL) view scores were 2.00 +/- 1.00 for direct view and 1.375 +/- 0.517 for the indirect view (CMAC). Success rates for backward intubation in the standard airway were 100% (CMAC) and 87.5% (DV). Average CL grades in the difficult airway were 3.63 +/- 0.74 (DV) and 2.00 +/- 0.926 (CMAC)(p = 0.002). The success rates for backward intubation of the difficult airway were 12.5% (DV) and 63% (CMAC). Our results show that in backward intubation of the difficult airway in a helicopter setting, the prototype CMAC Videolaryngoscope significantly improved the airway score by 1-2 grades and improved intubation success 5-fold. Studies using the portable CMAC Videolaryngoscope under challenging rescue conditions and positions should be considered.
