Team Planning

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.

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.

Background Intubation in children is increasingly performed using video laryngoscopes. Many pediatric studies examine novice laryngoscopists or describe single patient experiences. This prospective randomized nonblinded equivalence trial compares intubation time for the GlideScope Cobalt® video laryngoscope (GCV, Verathon Medical, Bothell, WA) with direct laryngoscopy with a Miller blade (DL, Heine, Dover, NH) in anatomically normal neonates and infants. The primary hypothesis was that intubation times with GCV would be noninferior to DL. Methods Sixty subjects presenting for elective surgery were randomly assigned to intubation using GCV or DL. Intubation time, time to best view, percentage of glottic opening score, and intubation success were documented. We defined an intubation time difference of less than 10 s as clinically insignificant. Results There was no difference in intubation time between the groups (GCV median = 22.6 s; DL median = 21.4 s; P = 0.24). The 95% one-sided CI for mean difference between the groups was less than 8.3 s. GCV yielded faster time to best view (median = 8.1 s; DL 9.9 s; P = 0.03). Endotracheal tube passage time was longer for GCV (median = 14.3 s; DL 8.5 s; P = 0.007). The percentage of glottic opening score was improved with GCV (median 100; DL 80; P < 0.0001). Conclusions Similar intubation times and success rates were achieved in anatomically normal neonates and infants with the GCV as with DL. The GCV yielded faster time to best view and better views but longer tube passage times than DL.

Nicolaides-Baraitser syndrome (NCBRS) is a rare congenital genetic disorder characterized by distinctive facial features similar to Treacher Collins syndrome (TCS). We report the first case of successful nasal fiberoptic intubation in a patient with NCBRS with micrognathia and limited mouth opening due to trismus. A 9-year-old girl with NCBRS and dental caries was scheduled to undergo general anesthesia for a dental extraction. Initial attempts at oral intubation using a video laryngoscope were unsuccessful. However, subsequent attempts at nasal intubation using a flexible fiberoptic scope were successful. This report highlights that patients with NCBRS may present with difficult airways to manage and intubate.

ABSTRACT Surgery of temporomandibular joint ankylosis under general anesthesia poses a great challenge to anesthesiologists. This surgery falls in the category of difficult intubation as direct vocal cord visualization is difficult due to an inability to open the mouth. The present case report suggests that the fiberoptic intubation has become an essential skill for anesthetists dealing with patients in whom orotracheal intubation is anatomically difficult.

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.

This study aims to present the dynamic UCLA as a prosthetic option to restore a tilted implant, replacing a missing maxillary left lateral incisor with a functional and aesthetic screw-retained crown. Dental implants show high success rates; however, complications related to three-dimensional positioning of the implant are common. The correction of the implant position usually requires machined angled abutments or complex surgical procedures, which results in long and difficult treatment, and increases the treatment final cost. A 45-years-old male patient sought for specialized dental care to restore the front missing tooth esthetic area. The patient has limited mouth opening, mental and physical disabilities, so the construction of a metal-ceramic prosthesis with the aid of dynamic UCLA was proposed as a straightforward and low-cost procedure under the sign of free and informed consent. The prosthetic treatment provided aesthetic results and patient satisfaction without complications after a four-year follow-up.

Glottic View

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

BackgroundAn airway assessment is usually best performed before an elective operation. But in an emergency operation, proper airway assessment can often be difficult. Fiberoptic intubation is a powerful and safe technique to deal with airway difficulty, but it requires a lot of training to be able to perform correctly. There are various specialized oral airways for fiberoptic intubation, but none of them have perfect functionality.CaseA 75-year-old male (body weight 71.6 kg, height 159.3 cm, body mass index 28.22 kg/m2) was diagnosed with acute appendicitis, and it was decided to do a laparoscopic appendectomy. After the induction of general anesthesia, it was impossible to insert the direct laryngoscope deep enough for vocal cord visualization without damaging the teeth because of limited mouth opening. We successfully performed fiberoptic intubation with a newly modified Guedel airway via a longitudinal channel on the convex side and a distal opened lingual end.ConclusionsOur modified Guedel airway can be useful in assisting fiberoptic intubation in unexpectedly difficult airway situations.
