BACKGROUND: Management of the airway in patients undergoing surgery is increasingly difficult. The airway management in the operating room in terms of the initial action of anesthesia is very important. Video-laryngoscopy has been shown to provide a better view of the larynx’s structure compared to direct visualization. AIM: We describe our experience using a custom made and inexpensive tool for a video-laryngoscopy. METHODS: This is an experimental research with single randomized clinical trial conducted at the Anesthesiology Department of Sanglah General Hospital Denpasar. There were 270 patients divides into three group with conventional, O-Mac® and Mc-GRATH™ BF laryngoscope, aged 18–65 years old, with Mallampati grade 1–2, randomly selected, and signed informed consent. RESULTS: Intubation time fastest with O-Mac® median 26 (15–36) s, p = 0.000. Laryngoscopy time fastest with O-Mac® median 5.5 (2–13 s), p = 0.000. O-Mac® does not use many tools, p = 0.000. All three did not prod...

Introduction: Aerosol box is a usefull tools to prevent aerosol and droplet contaminations during laryngoscopy and intubation in COVID-19 pandemic. Video laryngoscope is recommended during this era to increase the operator and patient’s distance during the procedure. However, many anesthesiologists still use direct laryngoscopes due to their availability and familiarity. This study aims to compare endotracheal tube intubation with video laryngoscope compared to direct laryngoscope in elective surgery patients. Methods: This study was a quasi-experimental study. The sample size in each group (video and direct laryngoscope) was 35 subjects. The primary outcome of this study was to compare the duration of intubation between video laryngoscope and direct laryngoscope, while the secondary outcome was to evaluate complications such as broken teeth and sore throat 24 hours post intubation. Results: Direct laryngoscope had shorter intubation duration than video laryngoscope [12.3 (8.9-21.0)...

Background: The essence of anaesthesia practice in every case is uneventful laryngoscopy and intubation. The current study compared the King Vision Video Laryngoscope (KVVL) channelled blade to the Macintosh laryngoscope (ML) in terms of laryngoscopic view, laryngoscopic time, and time required to complete tracheal intubation with the head in neutral position. We aimed to see if there were any drawbacks to using the King Vision Video Laryngoscope in routine clinical practice in terms of hemodynamics. Methods: Eighty patients undergoing elective surgery requiring general anaesthesia and tracheal intubation were randomly assigned to receive either the King Vision Video Laryngoscope or the Macintosh laryngoscope for tracheal intubation. Data were collected during and after laryngoscopy and endotracheal intubation which included laryngoscopic view, time and side effects after a standardised general anaesthetic. Results: The average tracheal intubation time (TTI) for the King Vision Video Laryngoscope and the Macintosh laryngoscope were 24.9 and 26.5 seconds, respectively (p =0.596). The mean duration of laryngoscopy (DOL) for the King Vision Video Laryngoscope and the Macintosh laryngoscope was 46.5 and 46.4 seconds, respectively (p = 0.925). Only 37.5% of the ML group had a Cormack Lehane grade 1 glottic view, whereas all of the KVVL group had a grade 1 glottic view. For KVVL and ML, the percentages of patients who did not require optimisation manoeuvres were 72.5% and 27.5%, respectively. Both groups experienced comparable changes in hemodynamic profile. Conclusion: The King Vision Video Laryngoscope has comparable efficacy in terms of intubation time, laryngoscopy duration, success rate, and ease of intubation. Although King Vision provided a higher percentage of the best laryngoscopic view with fewer optimization manoeuvres eventhough without statistical significance, it provides no additional benefit in European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 09, Issue 07, 2022 9648 terms of hemodynamic response to intubation. The need for a sniffing position is not needed in KVVL group. As a result, we conclude that the King Vision Video Laryngoscope can be used for tracheal intubation in routine clinical practice.

Intubation is a crucial medical procedure that involves the insertion of a tube into the airway to ensure proper breathing and save lives. This technique, which is fundamental in the field of anaesthesia, requires skill and precision. Anaesthesiologists play a key role in mastering, teaching, and performing intubations, making it a cornerstone of their practice for many years. Traditionally, machine learning has been utilized as a reliable method for tracheal cannulation, establishing itself as the gold standard over the past seven decades. In recent times, there has been a notable development in intubation technology with the introduction of alternative devices such as the King Vision Video Laryngoscope (KVVL). Unlike the conventional method that relies on direct visualization, the KVVL utilizes an indirect magnified image for enhanced accuracy during the procedure. A comparative study was conducted between the King Vision Video Laryngoscope and the traditional Macintosh Laryngoscope on two groups of patients, with Group A consisting of 70% male and 30% female, and Group B with 60% male and 40% female participants. The results of the study revealed that while BMI, thyromental distance, and MPC showed no significant differences between the two devices, the King Vision Video Laryngoscope outperformed the Macintosh Laryngoscope in terms of intubation difficulty score and Cormack Lehane grading. Moreover, the former demonstrated superior outcomes in terms of airway trauma, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and saturation levels, ensuring a smoother and safer intubation process overall. Based on these findings, the study concluded that the King Vision Video Laryngoscope offers distinct advantages over the traditional Macintosh Laryngoscope, highlighting its potential as a superior tool for efficient and effective airway management in clinical settings.

Introduction and Aims: Currently wide arrays of video laryngoscopes are available to facilitate laryngoscopy and endotracheal intubation in routine and difficult airway patients, intensive care units (ICU) and emergency settings. This study is undertaken to compare the efficacy of C-MAC and King Vision video laryngoscope for easy laryngoscopy and endotracheal intubation in patients with no predictors of difficult airway. Materials and Methods: 60 adult patients undergoing elective surgery were randomly allocated into 2 groups for intubation using either King Vision laryngoscope (KVL group) or C-MAC video laryngoscope (C-MAC group). The parameters recorded were need for external laryngeal manipulation, percentage of glottis opening (POGO score), Cormack Lehane grading, number of attempts and time taken for successful endotracheal intubation and the airway morbidity. Systolic, diastolic, mean blood pressure and heart rate were measured preoperatively and at 1 and 2 min following endotracheal intubation in both the groups. The obtained data were analysed using chi-square test and Student’s t-test using SPSS software. Results: The use of Kings Vision laryngoscope or CMAC video laryngoscope did not differ significantly with respect to good laryngoscopy and intubating conditions. But airway morbidity was significantly lower in the KVL group (10%) when compared with the C-MAC group (40%) p<0> Conclusions: The use of C-MAC or KVL provided excellent laryngoscopy and intubating conditions except for the airway morbidity and haemodynamic stability which were better with the use of KVL. Keywords: Video laryngoscopes, Endotracheal intubation, Airway morbidity, Haemodynamic changes

Intubation of Critically Ill COVID-19 Patients Using Conventional Laryngoscope in the ICU
Sri Lankan Journal of Anaesthesiology
Background: Video laryngoscopy is recommended for critically ill COVID-19 patients due to safety concerns and avoid complications. It is not available in some places and thereby forcing the operator to rely on conventional laryngoscope. Intubations in critically ill COVID-19 patients are challenging and may lead to adverse complications which may be affected by the laryngoscope used. The aim of the study was to analyse predictors of difficult intubation, complexity of intubation and complications of using conventional laryngoscopy in intubations of COVID-19 patients in ICU. Methods: A prospective observational study was done in COVID Intensive Care Unit of the Base Hospital- Teldeniya, Sri Lanka from 1st of January 2021 to August 2021. The data was collected using a Performa filled by operator at the end of the intubation. Apart from demographic data and clinical parameters, data related to intubation including MACOCHA score which is a validated score predicting difficult intubation...

Background: Video-laryngoscopes are marketed for intubation in difficult airway management. They provide a better view of the larynx and may facilitate tracheal intubation, but there is no adequately powered study comparing different types of video-laryngoscopes in a difficult airway scenario or in a simulated difficult airway situation. Methods/Design: The objective of this trial is to evaluate and to compare the clinical performance of three videolaryngoscopes with a guiding channel for intubation (Airtraq™, A. P. Advance™, King Vision™) and three videolaryngoscopes without an integrated tracheal tube guidance (C-MAC™, GlideScope™, McGrath™) in a simulated difficult airway situation in surgical patients. The working hypothesis is that each video-laryngoscope provides at least a 90% first intubation success rate (lower limit of the 95% confidence interval >0.9). It is a prospective, patient-blinded, multicenter, randomized controlled trial in 720 patients who are scheduled for elective surgery under general anesthesia, requiring tracheal intubation at one of the three participating hospitals. A difficult airway will be created using an extrication collar and taping the patients' head on the operating table to substantially reduce mouth opening and to minimize neck movement. Tracheal intubation will be performed with the help of one of the six devices according to randomization. Insertion success, time necessary for intubation, Cormack-Lehane grade and percentage of glottic opening (POGO) score at laryngoscopy, optimization maneuvers required to aid tracheal intubation, adverse events and technical problems will be recorded. Primary outcome is intubation success at first attempt. Discussion: We will simulate the difficult airway and evaluate different video-laryngoscopes in this highly realistic and clinically challenging scenario, independently from manufacturers of the devices. Because of the sufficiently powered multicenter design this study will deliver important and cutting-edge results that will help clinicians decide which device to use for intubation of the expected and unexpected difficult airway.

Background: Airway management and tracheal intubation in the ICU is a difficult procedure that may be concomitant with major complications. The purpose of this study was to evaluate the effect of the SANYAR ® video laryngoscope(S-VL) on laryngeal view and first Pass Success of tracheal Intubation compared with direct laryngoscopy. Methods: This comparative, prospective clinical study was conducted on 120 adult patients in a single-center, in a surgical ICU under the supervision of an anesthesiologist in a university hospital. Difficult airway predictors, glottic view, first Pass Success of tracheal Intubation and time of intubation were evaluated with Macintosh laryngoscopy (ML) or the SANYAR® Video Laryngoscope(S-VL). Results: Tracheal intubation was performed in 58 critically ill patients using ML and 62 patients using S-VL. According to Cormack and Lehane (C&L) grading glottic visualization was more difficult using ML (41%, C&L grade 3 and 4) compared with S-VL (13%, C&L grade 3 ...
A novel video laryngoscope for the use in hypoxemic COVID-19 patients: a case report
Critical Care Innovations, 2021
Critically ill COVID-19 patients require endotracheal intubations due to hypoxemic respiratory failure. These patients tend to desaturate fast especially during the intubation. Video laryngoscopes are recommended for airway management in COVID-19 patients due to better glottic view, higher first attempt success rates, less risk of contamination from airway secretions due to increased distance of patient's and intubator's face. Commercially available video laryngoscopes are expensive, difficult to acquire especially during pandemic and require training to use them. In order to overcome these issues, the authors designed a video laryngoscope by modifying the commonly used Macintosh laryngoscope blade which makes it easy to use, is low cost (approximately 90% cheaper than average cost of commercially available video laryngoscopes) and does not require any additional training. Moreover an oxygen channel was integrated along with the camera for deep laryngeal oxygen insufflation which has the additional advantage of delaying the desaturation during laryngoscopy. With these added advantages this modified video laryngoscope would prove to be a valuable tool for airway management team during current COVID-19 crisis.
