BACKGROUND AND AIMS: C-MAC(®) video laryngoscope (VL) with Macintosh blade has been found to improve Cormack-Lehane (C-L) laryngoscopic view as well as intubating conditions for orotracheal intubation. However, studies done on the performance of C-MAC(®) VL for nasotracheal intubation (NTI) are very few in number. Hence, we compared laryngoscopy and intubating conditions between Macintosh direct laryngoscope and C-MAC(®) VL for NTI. METHODS: Sixty American Society of Anesthesiologists Physical Status I, II patients, aged 8-18 years, posted for tonsillectomy surgeries under general anaesthesia with NTI were randomised, into two groups...

OBJECTIVES/HYPOTHESIS: To examine by intraoperative electric stimulation which peripheral facial nerve (FN) branches are functionally connected to which facial muscle functions. STUDY DESIGN: Single-center prospective clinical study. METHODS: Seven patients whose peripheral FN branching was exposed during parotidectomy under FN monitoring received a systematic electrostimulation of each branch starting with 0.1 mA and stepwise increase to 2 mA with a frequency of 3 Hz...

OBJECTIVE: Airway management in patients with suspected cervical spine injury is classified as a "difficult airway." The best device for managing difficult airways is not known. Therefore, we conducted an intubation study simulating patients with cervical spine injury using three devices: a conventional Macintosh laryngoscope, a video laryngoscope (GlideScope), and a fiberoptic bronchoscope (MAF-TM). Success rates, intubation time, and complication rates were compared. METHODS: Nine physician experts in airway management participated in this study...

The purpose of this investigation was to investigate the association between first attempt success and intubation-related complications in the Intensive Care Unit after the widespread adoption of video laryngoscopy. We further sought to characterize and identify the predictors of complications that occur despite first attempt success. This was a prospective observational study of consecutive intubations performed with video laryngoscopy at an academic medical Intensive Care Unit. Operator, procedural, and complication data were collected...

INTRODUCTION: In fetuses who are predicted to be at risk of catastrophic airway obstruction at delivery, the ex utero intrapartum treatment (EXIT) procedure is useful for securing the fetal airway while maintaining fetal oxygenation via placental circulation. Factors, including poor posture of the fetus and physician, narrow visual field, and issues of contamination in the aseptic surgical field, make fetal intubation during the EXIT procedure difficult. Herein, we report our experience of the usefulness of the GlideScope video laryngoscope (GVL) for intubation during the EXIT procedure...

BACKGROUND AND OBJECTIVES: Managing the airway of post burn contracture of the neck has always been challenging to anesthesiologists as it limits the alignment of oro-pharyngo-laryngeal axes because of functional and anatomical deformities that occur as a result of long standing contractures. Here the role of the King Vision video laryngoscope which is the latest in the series of video laryngoscope has been evaluated for such patients. CASE REPORT: A 35 year old male patient with post burn contracture of neck was scheduled for release of the contracture...

OBJECTIVE: The McGrath Video laryngoscope is a newly developed video laryngoscope that significantly improves laryngeal view and facilitates endotracheal intubation in difficult airways. However in patients with normal airway that is not mentioned before. The aim of this study was to compare the McGrath video laryngoscope with the Macintosh laryngoscope in patients with normal airways. METHODS: A total of 100 patients requiring orotracheal intubation, were randomized to either having intubation with the McGrath video laryngoscope or the Macintosh laryngoscope...

INTRODUCTION: Patients with severe pulmonary hemorrhage due to unilateral trauma or a bleeding cancer often present to the emergency department in acute respiratory distress. Although it is generally recommended to perform single lung intubation, most emergency department providers do not have access to or are not familiar with double-lumen endotracheal tubes, and blind insertion of an endotracheal tube to maximum depth does not ensure that the proper (nonhemorrhagic) lung is ventilated...

OBJECTIVE: The purpose of this study was to determine whether differences in long-term facial function outcomes following acute Lyme disease-associated facial palsy (LDFP) exist between patients who received antibiotic monotherapy (MT); dual therapy (DT) with antibiotics and corticosteroids; and triple therapy (TT) with antibiotics, corticosteroids, and antivirals. STUDY DESIGN: Retrospective cohort. METHODS: All patients with a prior diagnosis of unilateral LDFP who presented to our center between 2002 and 2015 were retrospectively assessed for inclusion...

STUDY DESIGN: Prospective clinical pilot study. METHODS: After several prior reconstructive attempts (following tumor resection, VF paralysis, in sulcus vocalis, and VF scarring), CaHA was injected under general anaesthesia using a transoral microlaryngoscopic approach in 10 patients with residual glottal insufficiency ≤1...

OBJECTIVE: To develop an ovine model for teaching suspension laryngoscopy and phonosurgery. METHODS: The head and neck from 10 pre-pubescent sheep were harvested following humane euthanasia at the end of an in vivo protocol. No live animals were used in this study. The tissues were saline-perfused and refrigerated for 1-5 days. Suspension laryngoscopy was performed using adolescent Parsons and adult Kantor-Berci laryngoscopes suspended with a Benjamin-Parsons laryngoscope holder...

BACKGROUND: Different video-laryngoscopes (VDLs) for endotracheal intubation (ETI) have recently been developed. We compared the performance of the VDL Airway Scope (AWS) with the direct laryngoscopy by Macintosh (DLM) for ETI success, time and learning. METHODS: We performed an experimental manikin controlled study. Twenty experienced (experts) and 40 inexperienced operators (novices) for DLM-ETI were enrolled. None of them had experience with the use of AWS-VDL...

Piriform sinus fistula (PSF) is a rare branchial anomaly that causes repetitive acute suppurative thyroiditis or deep neck abscess. The definitive treatment of PSF is open neck surgery. However, such surgery has a cosmetic problem and a high risk of recurrence. Furthermore, identifying the fistula is difficult due to previous repetitive infections. We report a case of esophageal submucosal abscess caused by PSF treated with endoscopic mucosal incision. The patient underwent transoral video laryngoscopic surgery (TOVS), and endoscopy as well as fluoroscopy revealed complete closure of PSF without any complication...

OBJECTIVES/HYPOTHESIS: Current imaging modalities lack the necessary resolution to diagnose subglottic stenosis. The aim of this study was to use optical coherence tomography (OCT) to evaluate nascent subglottic mucosal injury and characterize mucosal thickness and structural changes using texture analysis in a simulated intubation rabbit model. STUDY DESIGN: Prospective animal study in rabbits. METHODS: Three-centimeter-long sections of endotracheal tubes (ETT) were endoscopically placed in the subglottis and proximal trachea of New Zealand White rabbits (n = 10) and secured via suture...

DESIGN: Prospective, randomized, clinical trial. SETTING: University hospital operation room. PATIENTS: 104 patients scheduled for elective dental or maxillofacial surgery were randomized to two groups: GlideScope® classic (GSc) and GlideScope® direct (GSd). INTERVENTIONS: We compared the video laryngoscopes GSc and GSd with each other and with direct laryngoscopy (DL) for nasotracheal intubation with regard to visualization of the glottis, intubation success rate, and required time for and ease of intubation...

In addition to being effective and easy to learn how to use, the ideal laryngoscope should be associated with minimal reduction in skill performance during gaps in practice over time. We compared the time taken to intubate the trachea of a manikin by novice medical students immediately after training, and then after 1 month, with no intervening practice. We designed a two-period, four-group, randomised, cross-over trial to compare the Macintosh, Venner(™) A.P. Advance(™) with difficult airway blade, C-MAC(®) with D-Blade and Airtraq(®) with wireless video-viewer...
