Comparison of the new flexible tip bougie catheter and standard bougie stylet for tracheal intubation by anesthesiologists in different difficult airway scenarios: a randomized crossover trial
BMC Anesthesiology, 2020Co-Authors: Kurt Ruetzler, Michael Frass, Oliver Robak, Jacek Smereka, Cristian Abelairas-gomez, Marek Dabrowski, Szymon Bialka, Hanna Misiolek, Tadeusz Plusa, Olga AniolekAbstract:Background Incidence of difficult endotracheal intubation ranges between 3 and 10%. Bougies have been recommended as an airway adjunct for difficult intubation, but reported success rates are variable. A new generation flexible tip bougie appears promising but was not investigated so far. We therefore compared the new flexible tip with a standard bougie in simulated normal and difficult airway scenarios, and used by experienced anesthesiologists. Methods We conducted a observational, randomized, cross-over simulation study. Following standardized training, experienced anesthesiologists performed endotracheal intubation using a Macintosh blade and one of the bougies in six different airway scenarios in a randomized sequence: normal airway, Tongue Edema, pharyngeal obstruction, manual cervical inline stabilization, cervical collar stabilization, cervical collar stabilization and pharyngeal obstruction . Overall success rate with a maximum of 3 intubation attempts was the primary endpoint. Secondary endpoints included number of intubation attempts, time to intubation and dental compression. Results Thirty-two anesthesiologist participated in this study between January 2019 and May 2019. Overall success rate was similar for the flexible tip bougie and the standard bougie. The flexible tip bougie tended to need less intubation attempts in more difficult airway scenarios. Time to intubation was less if using the flexible tip bougie compared to the standard bougie. Reduced severity of dental compression was noted for the flexible tip bougie in difficult airway scenarios except cervical collar stabilization. Conclusion In this simulation study of normal and difficult airways scenarios, overall success rate was similar for the flexible tip and standard bougie. Especially in more difficult airway scenarios, less intubation attempts, and less optimization maneuvers were needed if using the flexible tip bougie.

Performance and skill retention of five supraglottic airway devices for the pediatric difficult airway in a manikin
European Journal of Pediatrics, 2018Co-Authors: Johannes Kulnig, Michael Frass, Lisa Füreder, Nicole Harrison, Oliver RobakAbstract:Supraglottic airway devices (SADs) have been introduced to assist medical professionals in emergency situations with limited experience in securing airways via conventional endotracheal intubation (ETI). Literature on the use of SADs for securing an airway during pediatric critical settings is scarce, and there is a lack of studies comparing different SADs to each other and to conventional ETI. We conducted a study comparing five different SADs to ETI with regard to success rate, time to first ventilation, and personal rating in a pediatric manikin under simulated physiologic and pathologic airway conditions in 41 pediatricians of varying clinical experience and training. Only the AirQ, AuraG, and laryngeal tube (LT) were inserted within 30 s correctly by all participants under physiologic conditions. In Tongue Edema (TE), AirQ and LT had the highest success rate. In limited mobility of the cervical spine (CS), AirQ, AuraG, and LT again all were inserted within 30 s. In a multivariate analysis, factors influencing the success were experience with the respective device and level of medical education. Under TE conditions, there were significantly longer insertion times for the ETI, laryngeal mask airway (LMA), and EzT. Under CS conditions, there were significantly longer insertion times for the ETI, LMA, LT, and EzT. A multivariate analysis showed experience with the respective device to be the only factor of influence on time to first ventilation. Conclusion : LT, AuraG, and AirQ were superior in providing fast and effective ventilation during simulated difficult airway situations in pediatricians. What is Known: • Supraglottic airway devices have been introduced for medical professionals who lack experience for managing difficult airway situations . • A variety of these devices have been developed so far, but not compared to each other yet . What is New: • We compared five different supraglottic airway devices with regard to success rate, time to first ventilation, and personal rating in a pediatric manikin under simulated physiologic and pathologic airway conditions . • Laryngeal tube, AuraG, and AirQ were superior in providing fast and effective ventilation during simulated difficult airway situations in pediatricians with varying clinical experience .

Feasibility and speed of insertion of seven supraglottic airway devices under simulated airway conditions.
Canadian Journal of Emergency Medicine, 2015Co-Authors: Oliver Robak, Marco Leonardelli, Konstantin Zedtwitz-liebenstein, Kurt Rützler, Ernst Schuster, Sonia J. Vaida, Ramez M Salem, Michael FrassAbstract:Objectives: Endotracheal intubation (ETI) is considered the gold standard for protecting the airway. Alternative devices for airway protection have been developed that can be used by untrained personnel, by those with less experience, and for when ETI is not possible. The main goals of our study were to evaluate the success rate and speed of insertion of different supraglottic airway devices and to determine whether the devices could be properly inserted under simulated critical conditions. Methods: Fifty medical students used an airway simulation trainer (Laerdal SimMan 3G) to assess the success rate and time used to insert seven different supraglottic airway devices under simulated physiologic and pathologic conditions in two different runs. Results: Although all airway devices could be inserted without problems, only the Combitube and the EasyTube could be successfully inserted in simulations of trismus, limited mobility of the cervical spine, or a combination of pathologic conditions such as trismus plus limited mobility of the spine and trismus plus Tongue Edema. The insertion time was significantly longer with LMA Unique, Fastrach, and I-Gel devices in both the first and second runs. Conclusion: The Combitube and the EasyTube were most easily inserted under simulated conditions such as trismus, limited mobility of the cervical spine, and combined pathologic conditions. Although all devices are useful for establishing an airway by nontrained medical students in standard simulations, we suggest that the Combitube and the EasyTube may offer advantages in difficult airway situations.

Novel airway device Vie Scope in several pediatric airway scenario: A randomized simulation pilot trial.
Medicine, 2020Co-Authors: Maciej Maslanka, Kurt Ruetzler, Lukasz Szarpak, Sanchit Ahuja, Jacek SmerekaAbstract:Endotracheal intubation of pediatric patients is challenging, especially in the pre-hospital emergency setting and if performed by less experienced providers. Securing an airway should be achieved with a single intubation attempt, as each intubation attempt contributes to morbidity and mortality. A new airway device, the VieScope, was recently introduced into clinical market, but efficacy to reduced intubation attempts remains unclear thus far. We aimed to compare endotracheal intubation by paramedics using the Vie Scope in different pediatric airway simulation conditions. We conducted a randomized, cross-over simulation study. Following a theoretical and practical training session, paramedics performed endotracheal intubation in 3 different pediatric emergency scenarios: normal airway; Tongue Edema; cardiopulmonary resuscitation using the VieScope. Overall intubation success rate was the primary outcome. Secondary outcomes included number of intubation attempts, time to intubation, Cormack-Lehane grade, POGO score, and ease of use (using 1-100 scale). Fifty-five paramedics with at least 2 years of clinical experience and without any previous experience with the VieScope participated in this study. The overall intubation success rate was 100% in all 3 scenarios. The median intubation time was 27 (24-34) versus 27 (25-37) versus 29 (25-40) s for scenarios A, B, and C, respectively. In scenario A, all paramedics performed successful intubation with 1 single intubation attempt, whereas 2% of the paramedics had to perform 2 intubation attempts in scenario B and 9% in scenario C. Results of this simulation study indicate preliminary evidence, that the VieScope enables adequate endotracheal intubation in the pediatric setting. Further clinical studies are needed to confirm these results.

Comparison of Macintosh and Intubrite laryngoscopes for intubation performed by novice physicians in a difficult airway scenario.
American Journal of Emergency Medicine, 2017Co-Authors: Lukasz Szarpak, Jacek Smereka, Jerzy Robert LadnyAbstract:Abstract Introduction In the difficult airway, the intubation skills are critically important. In selected cases, particularly in airway Edema, laryngeal or Tongue Edema, endotracheal intubation can turn out very difficult, and repeated attempts may even worsen the airway Edema, causing trauma and bleeding, and finally leading to complete airway obstruction and inability to ventilate the patient. Aim of the study The aim of the study was to compare the efficacy of endotracheal intubation performed by novice physicians using a standard Macintosh laryngoscope and an Intubrite videolaryngoscope. Material and methods The study was designed as a prospective, randomized, crossover, simulation study and continues our research assessing the effectiveness of selected endotracheal intubation techniques in prehospital settings. All participants were experienced with the Macintosh direct laryngoscope but remained novice to videolaryngoscopy. Instructions on the correct use of the Macintosh and Intubrite laryngoscopes were given before the procedure, and all the 30 novice physicians were allowed to practice at least 10 times before the study on manikin with normal airways. We employed an airway manikin (Trucorp Airsim Bronchi; Trucorp Ltd., Belfast, Northern Ireland) to simulate difficult airway, with was obtained by inflating the Tongue with 50 mL of air. The participants were asked to perform tracheal intubation using an endotracheal tube with 7.5 mm of internal diameter (Portex; Smiths Medical, Hythe, UK) through the vocal cords, applying either a conventional Macintosh laryngoscope with a size 3 blade (MAC; Mercury Medical, Clearwater, FL, USA) or the Intubrite videolaryngoscope, also with a Macintosh No. 3 blade (INT; Intubrite Llc, Vista, CA, USA). In both intubation techniques, a guide stylet (Rusch Inc., Duluth, GA, USA) was introduced into the endotracheal tube in order to obtain a C-shape curve to facilitate tracheal intubation. Each participating physician was randomly assigned to three attempts of tracheal intubation with each device. Results The effectiveness of the first intubation attempt using MAC and INT was 63.6% and 53.4%, respectively (p = 0.023), and the total percentage of intubation was 100% for both methods. The median time to intubation was 29.5 (interquartile range [IQR], 27–35.5) s with MAC, and 229 (IQR, 25.5–37) s with INT. The total of 24 physicians out of all study participants would choose MAC as a device to intubate with in real terms, while only 6 physicians would choose INT. Conclusions During the simulation study, the novice physicians were able to perform endotracheal intubation at the same time using both the Macintosh and Intubrite videolaryngoscope. However, the efficacy of the first intubation attempt was higher for MAC. Further studies are needed to confirm the results.

Fifty-five paramedics with at least 2 years of clinical experience and without any previous experience with the VieScope participated in this study. The overall intubation success rate was 100% in all 3 scenarios. The median intubation time was 27 (24-34) versus 27 (25-37) versus 29 (25-40) s for scenarios A, B, and C, respectively. In scenario A, all paramedics performed successful intubation with 1 single intubation attempt, whereas 2% of the paramedics had to perform 2 intubation attempts in scenario B and 9% in scenario C. Results of this simulation study indicate preliminary evidence, that the VieScope enables adequate endotracheal intubation in the pediatric setting. Further clinical studies are needed to confirm these results.

Comparison of the new flexible tip bougie catheter and standard bougie stylet for tracheal intubation by anesthesiologists in different difficult airway scenarios: a randomized crossover trial
BMC Anesthesiology, 2020Co-Authors: Kurt Ruetzler, Michael Frass, Oliver Robak, Jacek Smereka, Cristian Abelairas-gomez, Marek Dabrowski, Szymon Bialka, Hanna Misiolek, Tadeusz Plusa, Olga AniolekAbstract:Background Incidence of difficult endotracheal intubation ranges between 3 and 10%. Bougies have been recommended as an airway adjunct for difficult intubation, but reported success rates are variable. A new generation flexible tip bougie appears promising but was not investigated so far. We therefore compared the new flexible tip with a standard bougie in simulated normal and difficult airway scenarios, and used by experienced anesthesiologists. Methods We conducted a observational, randomized, cross-over simulation study. Following standardized training, experienced anesthesiologists performed endotracheal intubation using a Macintosh blade and one of the bougies in six different airway scenarios in a randomized sequence: normal airway, Tongue Edema, pharyngeal obstruction, manual cervical inline stabilization, cervical collar stabilization, cervical collar stabilization and pharyngeal obstruction . Overall success rate with a maximum of 3 intubation attempts was the primary endpoint. Secondary endpoints included number of intubation attempts, time to intubation and dental compression. Results Thirty-two anesthesiologist participated in this study between January 2019 and May 2019. Overall success rate was similar for the flexible tip bougie and the standard bougie. The flexible tip bougie tended to need less intubation attempts in more difficult airway scenarios. Time to intubation was less if using the flexible tip bougie compared to the standard bougie. Reduced severity of dental compression was noted for the flexible tip bougie in difficult airway scenarios except cervical collar stabilization. Conclusion In this simulation study of normal and difficult airways scenarios, overall success rate was similar for the flexible tip and standard bougie. Especially in more difficult airway scenarios, less intubation attempts, and less optimization maneuvers were needed if using the flexible tip bougie.
