BACKGROUND Video laryngoscope is an important tool for orotracheal intubation in anaesthesia practice particularly in difficult airways. It provides an indirect view of glottis without the need of alignment of oropharyngeal-laryngeal axis. We compared the intubation characteristics of channelled versus non-channelled blades of King VisionTM Video Laryngoscope. METHODS In this study 60 patients were randomly allocated to two groups; group C were intubated with channelled and group NC with non-channelled blade of King Vision. We measured time for glottis visualisation and intubation time using both blades. Percentage of glottis opening (POGO), insertion attempts, intubation attempts, and ease of intubation were also assessed. RESULTS The time for glottis visualisation was 8.5 ± 3 seconds for group C and 7 ± 2 seconds for group NC. Intubation time was 24 ± 8.5 seconds for group C and 44 ± 5 seconds for NC. There was no statistical difference in POGO, insertion attempts, intubation attempts and ease of intubation between the two groups. CONCLUSIONS We concluded that the time for glottis recognition is longer but intubation time is shorter when using King Vision video laryngoscope channelled blade as compared to non-channelled blade.

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.

Introduction: Direct laryngoscopy is associated with sympathetic stimulation and altered hemodynamics. A long intubation time may result in a greater in stress response. Alternative techniques using video laryngoscopes have been developed that do not require direct vocal cord visualization and may decrease the hemodynamic response. This study aimed to compare the difference between hemodynamic changes and intubation time with Airtraq video laryngoscope and conventionl Macintosh direct laryngoscope. Methods: A prospective randomized comparative study was conducted involving 100 adult patients who were undergoing elective surgeries under general anesthesia and endotracheal intubation. The patients were randomly assigned to group V (Video laryngoscope) or group D (Direct laryngoscope). In addition to the baseline vitals and vitals at various time intervals, intubation time was also recorded. We considered a difference in Heart Rate and Mean Arterial pressure of 20% to be clinically significant and statistical significance was p-value <0.05. Results: Significant difference was found in heart rates immediately after laryngoscopy (110.40 vs. 105.02 beats/minute; p<0.01) and 1 minute after intubation (109.30 vs. 106.20 beats/minute; p<0.01) with attenuation seen in video laryngoscopy group. Blood pressures were similar in both the groups at all times. Time for intubation was prolonged in video laryngoscopy group than that for direct laryngoscopy group (26.54 vs. 22.80 seconds; p<0.05). There were no adverse events associated with either of the techniques.  Conclusions: The Airtraq video laryngoscopy resulted in lesser change in heart rate and longer intubation time. However, clinical impact of such a difference seemed to be insignificant.

Intubation with a flexible fibrobronchoscope in an awake patient is frequently considered the technique of choice in patients with predicted difficult intubation. There are, however, situations in which the use of the fibrobronchoscope is not applicable, particularly due to problems attributable to the patient or to limited use of the instrument. In such situations, the video laryngoscope can be a useful alternative, as long as it is associated with adequate sedation of the patient. In fact, it ensures excellent viewing of the glottis, allowing for successful orotracheal intubation to be performed even in case of difficult airways, while keeping the patient spontaneously breathing throughout the procedure. From the data present in the literature, this technique seems to ensure a success rate and a safety profile similar to those obtained with the fibrobronchoscope, moreover, with greater ease of use by the anaesthesiologist. The main purpose of this work is to provide a valid and safe alternative to intubation with a fibrobronchoscope while awake in those patients with anticipated difficult airway management and in whom, for different reasons, fibrobronchoscope cannot be used.

Orotracheal intubation is considered the most delicate maneuver performed by anesthesiologists, and failure to manage the airways is one of the main causes of possible complications that can be catastrophic during its performance, thus requiring good team planning. Anatomical and / or physiological characteristics, such as limited mouth opening, a condition often found in patients suffering from fractures of the zygomatic arch or who have some abnormality in the temporomandibular joint (TMJ), can characterize a difficult airway, which demands attention greatest of the professional. Therefore, in order to overcome the obstacles that may occur during a difficult or unexpected intubation, new tools have been used, such as videolaryngoscopy in which an intubation device containing miniature video cameras is used in order to allow the operator has an indirect view of the glottis to increase success rates and decrease intubation time. The aim of the present study is to report a clinical case of a trauma victim, with limited mouth opening, who underwent intubation with the aid of a video laryngoscope after failed attempts at conventional intubation.

Abstract Background: We compared intubation conditions, intubation times, and hemodynamic response with the GlideScope video laryngoscope or the Macintosh direct laryngoscope in children older than one year. Methods: In total, 80 patients aged 1–12 years, scheduled to undergo elective surgery under general anesthesia with endotracheal intubation were included in a prospective, randomized trial.After standard anesthesia induction, patients were randomized into two groups.The group G patients(n = 40) were intubated with the GlideScope and the group M patients(n = 40) were intubated with the Macintosh laryngoscope.Intubation time, number of attempts,Cormack–Lehane score, airway maneuvers,visual analog score were recorded. Hemodynamic variables were recorded before and after anesthesia induction, at intubation, and one,three, and five minutes after intubation. Results: The demographic data and operation time were similar between the two groups. The intubation time was longer in Group G. The incidence of Cormack–Lehane score 1 was higher in Group G and that of Cormack–Lehane score 2 was higher in Group M. The hemodynamic parameters were similar between the two groups. Conclusion: We concluded that the GlideScope video laryngoscope provided better glottis visualization, but prolonged intubation time. No beneficial hemodynamic effect was found with the video laryngoscope.

Background. Video laryngoscopes provide better view and can improve ease of intubation compared with standard laryngoscopes. Methods. A prospective randomized study was done on 60 patients, 18 to 65 years old, comparing McGrath video laryngoscope and Macintosh laryngoscope. The aim was to compare the ease, efficacy, and usability of them during routine airway management. The primary endpoint was duration of intubation and the secondary endpoints were Cormack and Lehane grade of laryngoscopic view, number of intubation attempts, and incidence of complications. Results. There was an increase in total duration of intubation with McGrath video laryngoscope with 42.9 ± 19.5 seconds compared to Macintosh laryngoscope with 17.9 ± 4.6 seconds. In Macintosh group, 73.3% had grade I, 20% had grade II, and 6.7% had grade III Cormack Lehane view, while in McGrath group, 83.3% had grade I, 13.3% had grade II, and 3.3% had grade III. In McGrath group, 6 patients (20%) required more than 120 seconds to get intubated and only 73.3% were intubated in 1 attempt, while patients in Macintosh group had 100% successful intubation in 1 attempt. Pharyngeal trauma was seen with McGrath videolaryngoscopy. Conclusion. Duration of laryngoscopy, intubation, and total duration of intubation were significantly higher in McGrath group than in Macintosh group. McGrath group required a higher number of intubation attempts.

Video laryngoscope is one of best alternative in managing difficult airways. Our patient presented with left side neck pain and hoarseness of voice for three months, dysphagia to solids for two months. Computed tomography revealed large hypopharyngeal mass and a diagnosis of carcinoma of hypopharynx was made. As endoscopic Ryle’s tube insertion by gastroenterologist was unsuccessful so he was posted for Feeding jejunostomy under general anaesthesia. We anticipated difficult endotracheal intubation. Our first attempt to secure airway with awake fiberoptic bronchoscopic intubation was unsuccessful. Using an alternative method with bougie and video laryngoscopy, the trachea was successfully intubated. In rare clinical scenario fiberoptic bronchoscopic intubation may fail, hence we need to be prepared with the backup plan for airway management. A video laryngoscope might be useful in such situations.

The aim of this study was to evaluate the surface roughness of two Ormocer-based resin composites before and after mechanical toothbrushing. The study compared the brands Admira and Definite with composites based on conventional monomer systems (Bis-GMA, Bis-EMA, UEDMA e TEGDMA), Z250 and A110. Eight samples of each material with 4mm in diameter and 2mm in height were prepared using a metallic mold. After 24 hours they were polished and examined with a profilometer for measurement of the initial surface roughness (Ra, mm) before mechanical toothbrushing (30,000 cycles). After toothbrushing, the samples were taken to the profilometer once again to check the final surface roughness. The results were submitted to ANOVA and Tukey test (5%). The Admira composite presented a higher mean of surface roughness before toothbrushing (0.132mm), with a statistical difference from the composite A110 (0.082mm). Definite (0.110mm) and Z250 (0.105mm) composites showed no differences between themselves or among the other composites. No statistical differences were observed after toothbrushing between the composites Definite (0.178mm), Z250 (0.187mm), Admira (0.181mm), and A110 (0.193mm). All composites showed a statistically significant increase in the surface roughness after toothbrushing.
