Penatalaksanaan jalan napas merupakan hal fundamental bagi ahli anestesi. Kegagalan penatalaksanaan jalan napas mengakibatkan kematian. Berbagai modalitas tersedia untuk penatalaksanaan jalan napas  sulit, mulai dari alat sederhana seperti stylet dan bougie hingga alat canggih seperti video laryngsocope dan fiberoptic. Fiberoptik masih menjadi standar baku kesulitan intubasi, namun penggunaannya masih terbatas karena harganya mahal dan penggunaannya sulit. Purwarupa camera–bougie  merupakan modalitas baru yang diharapkan dapat mengatasi keterbatasan tersebut dan menjembatani antara bougie yang sederhana dan fiberoptik yang sangat canggih. Tujuan penelitian adalah membandingkan angka keberhasilan intubasi dan waktu intubasi antara bougie dan purwarupa camera–bougie pada maneken simulasi kesulitan intubasi di RSUP Dr. Hasan Sadikin Bandung. Penelitian analitik eksperimental ini dilakukan pada 41 peserta didik Program Pendidikan Dokter Spesialis (PPDS) Anestesiologi dan Terapi Intensif Fakultas Kedokteran Universitas Padjadaran/RSUP Dr. Hasan Sadikin Bandung semester 5 sampai dengan 11 yang melakukan intubasi dengan bougie dan purwarupa camera–bougie secara bergantian dengan metode randomisasi permutasi blok pada maneken simulasi kesulitan intubasi. Penelitian dilakukan dari tanggal 16–24 Oktober 2018. Keberhasilan dan waktu intubasi dicatat dan dianalisis secara statistik dengan Uji Mc. Nemar dan Wilcoxon. Keberhasilan intubasi dengan bougie sebesar 39% dan purwarupa camera-bougie 100% (p<0,001). Waktu intubasi dengan  bougie dan purwarupa camera-bougie sebesar 18,81 (12,19) detik dan  7,0 (1,47) detik (p<0,001). Simpulan, purwarupa camera–bougie meningkatkan keberhasilan intubasi dan memperpendek waktu intubasi pada maneken simulasi kesulitan intubasi.Comparison of Success Rate and Duration of Intubation between Bougie and Bougie–Camera Prototype in Simulated Difficult Airway ManikinAirway management is fundamental for anesthesiologist. Fiberoptic is still the gold standard for difficult intubation but its expensive price and complicated handling limit its use. Bougie–camera prototype is one of the new modalities that is expected to overcome these limitations and bridge the gap between simple bougie and very sophisticated fiberoptic. The aim of this study was to compare the success rate and duration of intubation between bougie and bougie–camera prototype in simulated difficult airway manikin at Dr. Hasan Sadikin General Hospital Bandung. This experimental analytic study was conducted on 41 fifth semester anesthesiology residents of the Faculty of Medicine, Universitas Padjadjaran/Dr. Hasan Sadikin General Hospital who performed intubation with bougie and bougie–camera prototype alternately on  simulated difficult airway mannequin using permutation block randomization method. This study was held during the period of 16–24th of October 2018. The success rate and duration of intubation were recorded and analyzed statistically by Mc. Nemar and Wilcoxon tests. The rate of successful intubation with bougie was 39% and 100% with bougie–camera prototype (p<0.001). Duration of intubation with bougie and bougie–camera prototype  was 18.81 (12.19) seconds and 7.0 (1.47) seconds (p<0.001). The conclusion of this study is bougie–camera prototype increases the success rate of intubation and shortens the duration of intubation on simulated difficult airway on mannequin.

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.

Background: The prevalence of obesity is increasing worldwide, and anesthesiologists are facing challenges in the airway management of such patients. Excessive adipose tissue influences pharyngeal spaces and affects the laryngoscopic grade. Standard ramp positioning is time-consuming and difficult to prepare, and requires expensive equipment. Objectives: The aim of this study was to compare the standard ramp position with the proposed low-cost and easily accessible modified ramp position in laryngoscopic view during the intubation of patients with morbid obesity. Methods: In this single-blind clinical trial, 84 patients candidate for bariatric surgery at Rasoul Akram Hospital in 2020 were assigned to the rapid airway management positioner (RAMP) (R) and new modified RAMP (MR) groups by the block randomization method. The laryngoscopic view of the glottis based on the Cormack-Lehane scale, ventilation quality, duration of intubation, intubation attempts, oxygen saturation at the end of intubation, and the need for backward, upward, rightward pressure (BURP) maneuver for successful intubation were recorded. Normal distribution tests and Mann-Whitney and Kruskal-Wallis tests were used to analyze the data. Results: The results showed no significant differences between the two groups regarding ventilation score, laryngoscopy grade, number of intubation attempts, duration of intubation, and the need for BURP maneuvers during intubation (P > 0.05). Conclusions: The two methods are not significantly different, and the new modified ramp position can be used with more ease and availability and less cost.

The introduction into clinical practice of new tools for intubation as videolaringoscopia has dramatically improved the success rate of intubation and the work of anesthesiologists in what is considered the most delicate maneuver. Nevertheless intubation difficulties may also be encountered with good anatomical visualization of glottic structures in videolaringoscopia. To overcome the obstacles that may occur both in a difficult provided intubation such as those unexpected, associated endotracheal introducer able to facilitate the passage of the endotracheal tube through the vocal cords into the trachea may be useful. We report 4 cases of difficult intubation planned and unplanned and completed successfully using the GlideScope videolaryngoscope associated with endotracheal Frova introducer.

Adequate Oxygenation

In difficult airway situations, the next step of the airway management method is selected according to the prior presence of difficulties in mask ventilation and endotracheal intubation. It is important for the practitioner to be calm, quick in judgment, and take action in cases of difficult intubation. Recently, high-flow nasal oxygenation has been rapidly introduced into the anesthesiology field. This technique could extend the safe apnea time to desaturation. Especially, it maintains adequate oxygenation even in apnea and allows time for intubation or alternative airway management. We report two cases in which high-flow nasal oxygenation was implemented in the middle of the induction process after quick judgment by clinicians. High-flow nasal oxygenation was successfully used to assist in prolonging the safe apnea time during delicate airway securing attempts.

Intubating Laryngeal Mask Airway

Background The intubating laryngeal mask airway (ILMA; Fastrach; Laryngeal Mask Company, Henley-on-Thames, UK) may provide an alternative technique to fiberoptic intubation (FIB) to facilitate the management of the anticipated difficult airway. The authors therefore compared the effectiveness of the ILMA with FIB in patients with anticipated difficult intubation. Methods One hundred patients, with at least one difficult intubation criteria (Mallampati class III or IV, thyromental distance &lt; 65 mm, interincisor distance &lt; 35 mm) were enrolled (FIB group, n = 49; ILMA group, n = 51) in this prospective randomized study. Anesthesia was induced with propofol and maintained with alfentanil and propofol after an efficient mask ventilation has been demonstrated. The success of the technique (within three attempts), the number of attempts, duration of the successful attempt, and adverse events (oxygen saturation &lt; 90%, bleeding) were recorded. Results The rate of successful tracheal intubation with ILMA was 94% and comparable with FIB (92%). The number of attempts and the time to succeed were not significantly different between groups. In case of failure of the first technique, the alternative technique always succeeded. Failures in FIB group were related to oxygen desaturation (oxygen saturation &lt; 90%) and bleeding, and to previous cervical radiotherapy in the ILMA group. Adverse events occurred significantly more frequently in FIB group than in ILMA group (18 vs. 0%, P &lt; 0.05). Conclusion The authors obtained a high success rate and comparable duration of tracheal intubation with ILMA and FIB techniques. In patients with previous cervical radiotherapy, the use of ILMA cannot be recommended. Nevertheless, the use of the ILMA was associated with fewer adverse events.

Abstract Objective: Difficult intubation is associated with an increasing number of endotracheal intubation attempts. Repeated endotracheal intubation attempts are in turn associated with an increased risk of adverse events. Clinical prediction tools to predict difficult airway have limited application in emergency airway situations. This study was performed to develop a new model for predicting difficult intubation in the emergency department.Methods: This retrospective study was conducted using an exploratory model at the Emergency Medicine of Ramathibodi Hospital, a university-affiliated super-tertiary care hospital in Bangkok, Thailand. The study was conducted from June 2018 to July 2020. The inclusion criteria were an age of ≥15 years and treatment by emergency intubation in the emergency department. Difficult intubation was defined as a Cormack–Lehane grade III or IV laryngoscopic view. The predictive model and prediction score for detecting difficult intubation were developed by multivariable regression analysis.Results: During the study period, 617 patients met the inclusion criteria; of these, 83 (13.45%) had difficult intubation. Five independent factors were predictive of difficult intubation. The difficult airway assessment score that we developed to predict difficult airway intubation had an accuracy of 89%. A score of >4 increased the likelihood ratio of difficult intubation by 7.62 times.Conclusion: A difficult airway assessment score of >4 was associated with difficult intubation.

Glottic View

Over the last decades several indirect laryngoscopes have been developed to provide a significant better glottic view and improved the success rate in difficult intubations. Some case reports describe the use of indirect laryngoscopes for awake tracheal intubations under preserved spontaneous breathing. However, randomized clinical studies comparing indirect laryngoscopy to the standard of fiberoptic intubation under spontaneous breathing are rare. Therefore, we compared the intubation with the Airtraq® laryngoscope and the Bonfils endoscope, to the standard fiberoptic intubation in patients with an expected difficult intubation under local anesthesia and sedation. 150 patients with an expected difficult intubation were randomized to one of the three devices. All intubation attempts were performed under local anesthesia and sedation. We evaluated success rate, time for intubation and the satisfaction of anesthesiologists and patients. Fiberoptic intubation was significantly more successful (100%) than intubation with an Airtraq® laryngoscope (88%) or the Bonfils endoscope (88%). Time for intubation was quickest with the Airtraq® laryngoscope and significantly shorter than fiberoptic intubation (p=0.044). There was no difference in satisfaction of the anesthesiologists and none of the patients had a negative recall to one of the techniques. An expected difficult intubation can be managed using the Airtraq® laryngoscope or the Bonfils endoscope in 88% and shows the same satisfaction of anesthesiologists and patient. We conclude that these techniques represent an acceptable alternative for an awake tracheal intubation under sedation and preserved spontaneous breathing.

The purpose of this study was to review literature that looked into the efficacy of the Glidescope video laryngoscope versus the Macintosh laryngoscope in oral endotracheal intubations. We aimed to answer the question ‘Should the Glidescope video laryngoscope laryngoscopes be used as first line intubation aids or only in the difficult airway?’ A systematic search of electronic databases was made. The inclusion criteria included: Glidescope, video laryngoscope, and Macintosh laryngoscope in human studies. The study aimed to compare first attempt success rate, glottic view and intubation time in papers dating between 2009 and 2017. Eleven trials with a total of 7,919 patients with both difficult and normal airways were included. The trials showed an improvement in first attempt success rate and glottic view with the Glidescope video laryngoscope especially in those with difficult airways. Overall time to intubate showed no significant differences between the Glidescope video laryngoscope and the Macintosh laryngoscope although it was identified that with increased training and experience with the Glidescope video laryngoscope, intubation time was reduced. Glidescope video laryngoscopes show advantages over the Macintosh laryngoscopes in obtaining better glottic views in those with difficult airways. However its use is not supported in all routine intubations.
