The use of both a video laryngoscope and a video intubation stylet, compared with the use of a direct laryngoscope, is not only easier to learn but also associated with a higher success rate in performing endotracheal intubation for novice users. However, data comparing the two video devices used by novice personnel are rarely found in literature. Nondelayed intubation is an important condition to determine the prognosis in critically ill patients; hence, exploring intubation performance in various situations is of clinical significance. This study is aimed at comparing a video stylet and a video laryngoscope for intubation in an airway manikin with normal airway and cervical spine immobilization scenarios by novice personnel. We compared the performance of intubation by novices between the Aram Video Stylet and the McGrath® MAC video laryngoscope in an airway manikin. Thirty medical doctors with minimal experience of endotracheal intubation attempted intubation on a manikin five times with each device in each setting (normal airway and cervical spine immobilization scenarios). The order of use of the devices in each scenario was randomized for each participant. In the normal airway scenario, the Aram stylet showed a significantly higher rate of successful intubation than the McGrath® (98.7% vs. 92.0%; odds ratio (95% CI): 6.4 (1.4–29.3); p = 0.006 ). The intubation time was shorter using the Aram Stylet than that using the McGrath® video laryngoscope ( p < 0.001 ). In the cervical immobilization scenario, successful endotracheal intubation was also more frequent using the Aram stylet than with the McGrath® (96.0% vs. 87.3%; odds ratio (95% CI): 3.5 (1.3–9.0); p = 0.007 ). The Aram Stylet intubation time was shorter ( p < 0.001 ). In novice personnel, endotracheal intubation appears to be more successful and faster using the Aram Video Stylet than the McGrath® MAC video laryngoscope.

Randomized Crossover Study

Purpose. Emergency physicians are at risk for infection during invasive procedures, and the respirators can reduce this risk. This study aimed to determine whether endotracheal intubation using direct laryngoscopes affected protection performances of respirators. Methods. A randomized crossover study of 24 emergency physicians was performed. We performed quantitative fit tests using respirators (cup type, fold type without a valve, and fold type with a valve) before and during intubation. The primary outcome was respirators’ fit factors (FF), and secondary outcomes were acceptable protection (percentage of scores above 100 FF [FF%]). Results. 24 pieces of data were analyzed. Compared to fold-type respirator without a valve, FF and FF% values were lower when participants wore a cup-type respirator (200 FF [200-200] versus 200 FF [102.75–200], 100% [78.61–100] versus 74.16% [36.1–98.9]; all P<0.05) or fold-type respirator with a valve (200 FF [200-200] versus 142.5 FF [63.50–200], 100% [76.10–100] versus 62.50% [8.13–100]; all P<0.05). There were no significant differences in intubation time and success rate according to respirator types. Conclusions. Motion during endotracheal intubation using direct laryngoscopes influenced the protective performance of some respirators. Therefore, emergency physicians should identify and wear respirators that provide the best personalized fit for intended tasks.

Background: The suction-assisted laryngoscopy and airway decontamination (SALAD) techniques (level 1, SALAD-1 and level 2, SALAD-2) are newly proposed airway management skills to facilitate endotracheal intubation in patients with massive haematemesis. A pilot study using GlideScope® demonstrated the superior performance of SALAD-1 technique in massive haematemesis simulation. Objectives: To compare the performance of three different video laryngoscopes (the GlideScope®, the Airtraq® and the C-MAC®) in endotracheal intubation using SALAD techniques by emergency doctors in a manikin simulating massive haematemesis. Methods: Forty-eight emergency doctors were recruited. The participants’ performance of endotracheal intubation using the GlideScope®, the Airtraq® and the C-MAC® with the conventional and the two SALAD techniques in a manikin simulating massive haematemesis was evaluated. The time for intubation, number of attempts, rate of failed intubation, amount of aspirated fluid and the subjective ease of different devices and techniques were compared. Results: The C-MAC® had shorter intubation time compared with GlideScope® when using conventional (mean intubation time: 28.48 vs 47.00 s, p = 0.018) and SALAD-1 technique (mean intubation time: 29.35 vs 43.25 s, p < 0.039). The intubation time of all three video laryngoscopes was similar in SALAD-2 technique. There was no significant difference in the number of attempts and failed intubation rate among different video laryngoscopes in using different techniques. Intubation with the C-MAC® resulted in the least mean amount of aspiration in all the conventional (35.63 mL), SALAD-1 (14.06 mL) and SALAD-2 (18.13 mL) techniques. However, the results were not significantly different from the GlideScope® and the Airtraq®. The C-MAC® was rated the most favourable video laryngoscope for the SALAD-1 technique (p < 0.001). There was no significant preference for different video laryngoscopes in using the SALAD-2 technique (p = 0.111). Conclusion: All the video laryngoscopes have similar intubation performance with the SALAD-1 and SALAD-2 techniques. The C-MAC® performed better than GlideScope® in terms of intubation time. The C-MAC® was the most favourable video laryngoscope for the SALAD-1 technique.

Background. Ease of endotracheal intubation with C-MAC video laryngoscope (VLS) with Miller blades 0 and 1 has not been evaluated in children.Methods. Sixty children weighing 3–15 kg with normal airway were randomly divided into two groups. Intubation was done with C-MAC VLS Miller blade using either nonstyletted endotracheal tube (ETT) (group WS) or styletted ETT (group S). The time for intubation and total procedure, intubation attempts, failed intubation, blade repositioning or external laryngeal maneuver, and complications were recorded.Results. The median (minimum/maximum) time for intubation in group WS and group S was 19.5 (9/48) seconds and 13.0 (18/55) seconds, respectively (p=0.03). The median (minimum/maximum) time for procedure in group WS was 30.5 (18/72) seconds and in group S was 24.5 (14/67) seconds, respectively (p=0.02). Intubation in first attempt was done in 28 children in group WS and in 30 children in group S. Repositioning was required in 14 children in group WS and in 7 children in group S (p=0.06). There were no failure to intubate, desaturation, and bradycardia in both groups.Conclusion. Styletted ETT significantly reduces time for intubation and time for procedure in comparison to nonstyletted ETT.

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.

Introduction: Laryngoscopy and endotracheal intubation are the two essential procedures when general anaesthesia is administered to a patient. Adverse responses in the cardiovascular, respiratory, and other physiological systems can be provoked due to the noxious stimuli produced by laryngoscopy and intubation.1 During general anaesthesia maintenance of airway and ventilation can be done in various ways. Aims & Objectives: To assess the superiority of video laryngoscopy over direct laryngoscopy using baseline parameters like heart rate, systolic blood pressure, diastolic blood pressure and mean blood pressure. Materials And Methods: Interventional, Randomized study. Operation theatre of Durgapur Steel Plant Hospital, Durgapur, West Bengal. Adult males and females, ASA physical Grade 1 and 2 patients, scheduled for elective surgeries, under General Anesthesia, requiring or tracheal intubation. 1 year. From February 2018 to February 2019. Result And Analysis:In Group-A (MDL), 28(56.0%) patients had MPG 1 and 22(44.0%) patients had MPG 2. In Group-B (KVVL), 29(58.0%) patients had MPG 1 and 21(42.0%) patients had MPG 2. Association of MPG vs. group was not statistically signicant (p=0.8399). In Group-A (MDL), the mean time taken for intubation (mean±s.d.) of patients was 34.5600 ± 2.3661. In Group-B (KVVL), the mean time taken for intubation (mean±s.d.) of patients was 20.4000 ± 1.7728. Distribution of mean time taken for intubation vs. group was statistically signicant (p<0.0001). Conclusion: Also, Kingvision video laryngoscope offered less intubation time and reduced hemodynamic responses in patients with ASA grade 1and 2 as compared to Macintosh laryngoscope. So further study can be done on patients with difcult airways (III-IV) and with different co morbidities (ASA 3,4, E) to evaluate whether using Kingvision video laryngoscope can be advantageous in reducing intubation time and obtunding hemodynamic responses to laryngoscopy and intubation.

Abstract Background: Successful early endotracheal intubation improves neurological outcomes in cardiopulmonary resuscitation. However, endotracheal intubation should not compromise cardiopulmonary resuscitation effectiveness and thus requires experience. The use of videolaryngoscopes might decrease the number of attempts as well as the time needed for intubation, especially among novice users. We sought to compare videolaryngoscopes with direct laryngoscopy in simulated cardiopulmonary resuscitation scenarios in mannequins by novices.Methods: Forty-four medical students were recruited to serve as novice users. Following brief, standardized training, students were asked to execute endotracheal intubation with each of the devices, including the King Vision®, the Macintosh laryngoscope and the VividTrac®, on acardiopulmonary resuscitation trainer (Ambu Man Advanced®) in normal and difficult airway scenarios. We evaluated the time to and the 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 (P < 0.05) were measured by King Vision®than by Macintosh laryngoscope. However, VividTrac® was proven to be similar (P > 0.05) to Macintosh laryngoscope in this regard in the normal airway scenario. In the difficult airway scenarios, we found VividTrac® superior (P < 0.05) to King Vision® and Macintosh laryngoscope regarding laryngoscopy times, but there were no significant differences between devices in intubation times. In both normal and difficult airway cardiopulmonary resuscitation scenarios, we noted no difference (P > 0.05) in first attempt success rates, the best view of the glottis and dental trauma, but esophageal intubation and the use of bougie were more frequent (P < 0.05) withMacintosh laryngoscopethan with videolaryngoscopes. The shortest tube insertion times were related to King Vision® in both scenarios.Conclusion: Based upon our results, King Vision®was superior to Macintosh laryngoscoperegarding intubation time in the normal airway cardiopulmonary resuscitation scenario for novice users. We noted significantly less esophageal intubationwhen using videolaryngoscopes compared to Macintosh laryngoscope in both scenarios; thus,videolaryngoscopes might be recommended for novice users for both cardiopulmonary resuscitation scenarios.

Background: Endotracheal intubation is an essential primary skill for all anesthesiologists. For cardiac anesthesiologists rapid and proper intubation is more important as failure may cause serious consequences. Video laryngoscope provides a better real time view of the larynx, epiglottis and vocal cords. It also keeps the intubating anesthetist away from the patient as compared to conventional laryngoscopy. This may be very important in this COVID-19 era. To the best of our knowledge the Department of Cardiac Surgery and Cardiac Anesthesia of Chattogram Medical College & Hospital is the first center in Bangladesh to introduce video laryngoscope in cardiac OT. The objective of this study was aimed to compare the intubation time, hemodynamic response to laryngoscopy, success rates and operator’s comfort using the conventional Macintosh laryngoscope and video laryngoscope in adult patients undergoing cardiac surgery. Materials and Methods: A total of 60 adult patients were included in this comparative study, subjected to general anesthesia for cardiac surgery, intubated using either conventional Macintosh direct laryngoscope or video laryngoscope. Patients were intubated by 3 different consultant anesthesiologists with equal competency of our department. Results: There was not much difference between Video laryngoscopy and conventional laryngoscopy in terms of intubation time and success rate. Video laryngoscopy exhibited less hemodynamic response to laryngoscopy and intubation; however, the difference was not statistically significant in this small group of patients. Operators were much more comfortable with Video laryngoscope than conventional laryngoscope particularly with the cases of difficult intubation because of the better glottic view with the former. Conclusion: Video laryngoscope is preferred by cardiac anesthetists because of better glottic view. Bangladesh Heart Journal 2020; 35(1) : 47-53
