Tracheal intubation is a commonly done procedure in neonatal intensive care unit and delivery room during resuscitation. The confirmation of endotracheal tube (ETT) position should be done quickly as tube malposition is associated with various serious adverse outcomes like hypoxemia, right upper lobe collapse, atelectasis, air leak syndromes and esophageal intubation. ETT position can be confirmed by various methods like clinical sign, chest radiography, capnography, external digital tracheal palpation, ultrasonography (USG), respiratory function monitor, video-laryngoscope and fiberoptic devices...

D-blade is a relatively new device in the field of videolaryngoscopy, designed for airway management by enabling indirectoscopic glottic view. In our study, we investigated efficiency of D-blade in comparison with direct Macintosh laryngoscope (gold standard). Fifty-two adult patients with normal airway scheduled for elective surgery in general anesthesia were randomly assigned in D-blade video or direct Macintosh group. In the first video group, patients were laryngo-scoped and intubated by D-blade, and in the second group laryngoscopy and intubation were performed by Macintosh laryngoscope...

Background and Aims: The Airtraq™ video laryngoscope facilitates tracheal intubations in patients with difficult airway or cervical spine immobilization. However, curved reinforced tracheal tube and straight reinforced tracheal tubes are useful where neck of the patient is likely to be moved or flexed or if patient is in prone position, wherein nonreinforced endotracheal tube (ETT) might get kinked and/or compressed. We compared intubation success rate of curved and straight reinforced tracheal tubes with polyvinyl chloride (PVC) tracheal tube using Airtaq™ laryngoscope in paralyzed and anesthetized patients...

In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device...

Tracheal intubation via laryngeal exposure has evolved over the past 150 years and has greatly expanded in the last decade with the introduction and development of newer, more sophisticated optical airway devices. The introduction of indirect and video-assisted laryngoscopes has significantly impacted airway management as evidenced by the presence of these devices in the majority of published difficult airway algorithms. However, it is quite possible that many airway managers do not have a thorough comprehension of how these devices actually function, an understanding that is vital not only for their use but also for assessing the devices' limitations...

Peter S Popolo
OBJECTIVE: High-speed videolaryngoscopy is widely used in voice practices as a complement to videostroboscopy, especially when it is desired to visualize asymmetric and nonperiodic vocal fold vibration or voice onset and offset. Because of the requirement for greater illumination at higher frame rates, the high-speed exam is usually performed with a rigid transoral laryngoscope. Although it is possible to obtain color high-speed video images with a flexible fiberoptic nasoendoscope, the results are often disappointing because of the inability to provide adequate lighting inside the larynx...

Anterior laryngeal web is a rare anomaly which is usually asymptomatic in infancy. This translates into a high incidence of unanticipated difficult intubation in these patients with consequent airway morbidity in the form of tracheostomy. We are reporting a case of unsuspected difficult intubation in a neonate due to the presence of a congenital anterior laryngeal web. After multiple failed intubation attempts with direct laryngoscopy, use of CMAC video laryngoscope improved the glottic view, enabled us to diagnose the presence of a thick anterior laryngeal web and intubate the child...

PURPOSE: The GlideScope(®) video laryngoscope (GVL) is widely used for nasotracheal intubation in dental and facial plastic surgery. The angle of the Magill forceps is different from that of the GVL blade, which suggests that the Magill forceps are not the ideal forceps for use with the GVL. The purpose of this study was to compare the effectiveness of the Magill forceps vs vascular forceps for nasotracheal intubation using the GVL. METHODS: This study included 60 patients scheduled to undergo elective surgery requiring nasotracheal intubation...

BACKGROUND: With the increasing popularity of video laryngoscopy during intubation of pediatric patients with normal or difficult airways, fiberoptic-assisted tracheal intubation, traditionally considered the gold standard for difficult intubation, may become underused. AIM: We aimed to assess the use of airway management techniques before and after introduction of video laryngoscopy in a cohort of school-aged children with microtia, who are at increased risk of difficult intubation...

Intraoperative airway obstruction is perplexing to anesthesiologists because the patient may fall into danger rapidly. A 74-year-old woman underwent an emergency incision and drainage for a deep neck infection of dental origin. She was orally intubated with a 6. 0 mm internal diameter reinforced endotracheal tube by video laryngoscope using volatile induction and maintenance anesthesia (VIMA) with sevoflurane, fentanyl (100 µg), and succinylcholine (75 mg). During surgery, peak inspiratory pressure increased from 22 to 38 cmH2O and plateau pressure increased from 20 to 28 cmH2O...

OBJECTIVE: Head and neck ultrasonography (HNUS) increasingly is used as a point-of-care diagnostic tool by otolaryngologists. However, ultrasonography (US) is a very operator-dependent image modality. Hence, this study aimed to explore the diagnostic accuracy of surgeon-performed HNUS and to establish validity evidence for an objective structured assessment of ultrasound skills (OSAUS) used for competency-based assessment. STUDY DESIGN: A prospective experimental study...

The laryngeal adductor reflex (LAR) is an airway protective reflex that manifests as a brief vocal fold closure in response to laryngeal stimulation. This study examined if the absence of the LAR in response to touch delivered by a laryngoscope is associated with penetration/aspiration or pneumonia in patients with dysphagia. Inpatients at a teaching hospital with clinical symptoms of dysphagia were recruited upon referral to the otolaryngology clinic for a swallowing evaluation. Otolaryngologists observed the status of secretions and touched each arytenoid with the tip of the laryngoscope...

INTRODUCTION: Emergency management of upper cervical spine injuries often requires cervical spine immobilisation and some critical patients also require airway management. The movement of cervical spine created by tracheal intubation and cervical spine immobilisation can potentially exacerbate cervical spinal cord injury. However, the evidence that previous studies have provided remains unclear, due to lack of a direct measurement technique for dural sac's space during dynamic processes...

PURPOSE: It is generally accepted that using a video laryngoscope is associated with an improved visualization of the glottis. However, correctly placing the endotracheal tube might be challenging. Channeled video laryngoscopic blades have an endotracheal tube already pre-loaded, allowing to advance the tube once the glottis is visualized. We hypothesized that use of a channel blade with pre-loaded endotracheal tube results in a faster intubation, compared to a curved Macintosh blade video laryngoscope...

Nasotracheal intubation (NTI) is usually required in patients undergoing maxillofacial surgery. Though video-scopes have been demonstrated to perform well in oral endotracheal intubation, limited information is available concerning NTI. The aim of the study is to compare the efficiency of video-scopes and the traditional direct laryngoscopy in NTI. One hundred and eight patients scheduled for elective oro-maxillofacial surgery under nasotracheal intubation general anesthesia were randomly allocated into one of 3 groups of GlideScope, Pentax AirWay Scope, or Macintosh laryngoscope respectively...

Objective To determine whether intubation education using the Pentax Airway Scope (AWS) in normal airways is more useful than direct laryngoscopy (Macintosh laryngoscope) in novice personnel. Methods Eleven intern doctors without intubation experience performed 60 sequential intubations with each device on a manikin and 10 sequential intubations in adult patients. The time required for successful intubation, percentage of glottic opening (POGO) score, number of intubation attempts, and number of dental injuries were analyzed for each intubation technique...

INTRODUCTION: The direct laryngoscopy technique using a Macintosh blade is the first choice globally for most anaesthetists. In case of an unanticipated difficult airway, the complication rate increases with the number of intubation attempts. Recently, McGrath MAC (McGrath) video laryngoscopy has become a widely accepted method for securing an airway by tracheal intubation because it allows the visualisation of the glottis without a direct line of sight. Several studies and case reports have highlighted the benefit of the video laryngoscope in the visualisation of the glottis and found it to be superior in difficult intubation situations...
