To evaluate the feasibility of a 980-nm contact diode laser (CDL) as a method for creating a posterior laryngofissure in live pigs. Twenty-eight Landrace pigs (15-20 kg) were anesthetized, intubated, ventilated, and submitted to a cervical tracheostomy. An anterior and posterior midline longitudinal laryngofissure incision was created according to randomization-control (n = 4), posterior laryngofissure with a scalpel blade; electrocautery (n = 12), posterior laryngofissure by electrocautery (10, 15, 20, 25 W powers); CDL (n = 12), posterior laryngofissure by the CDL (10, 15, 20, 25 W peak powers in pulsed mode)...

Background and Aims: Paediatric airway needs special consideration as it is not a miniature replica of adult airway, rather it has different anatomy with different proportion and angulations. This study was conducted with the aim to find a laryngoscope blade that provides best laryngoscopic and intubation conditions in paediatric patients of age 2-6 years. Methods: This trial was conducted in a total of 75 children age 2-6 years, either gender, with American Society of Anesthesiologists grade I or II scheduled for elective surgery under general anaesthesia...

BACKGROUND: Airway Scope (AWS) with its plastic blade does not require a head-tilt or separate laryngoscopy to guide intubations. Therefore, we hypothesized that its use would reduce the intubation time (IT) and the frequency of airway complication events when compared with the use of Macintosh Laryngoscope (ML) for infants with cleft lip and palate (CLP). METHODS: The parents of all patients provided written consents; we enrolled 40 infants with CLP (ASA-PS 1)...

Rabbits provide a unique challenge for routine endotracheal intubation in clinical practice because of various distinctiveanatomic and physiologic features. Many previously proposed methods for endotracheal intubation in rabbits are limited byseveral factors, including the needs for expensive equipment and high levels of technical expertise. We evaluated capnographyfor its effectiveness in assisting endotracheal intubation in rabbits. New Zealand white rabbits were divided into 3 groupsof 5 animals. In the first 2 groups, mainstream (nondiverting) or sidestream (diverting) capnography (MC and SC groups, respectively)was used; in the third group (LS group), a laryngoscope with a size 00 Miller blade was used to guide endotracheal tube placement...

Neonatal intubation is an essential but difficult skill to learn. Videolaryngoscopy allows the airway view to be shared by the intubator and supervisor and improves intubation success. Ideally, a videolaryngoscope (VL) should be usable as a conventional laryngoscope (CL). The aims of this report were to describe differences in the shape of currently available CL and VL blades and to compare the direct airway view obtainable on a neonatal manikin with different laryngoscope blades.Three main differences were observed; compared with CL, the VL blades have a reduced vertical height, a curved tip and curved body...

BACKGROUND: Videolaryngoscopy has an established role in difficult airway management in adults. However, there is limited literature to support their efficacy in children. The Truview Picture Capture Device has shown promising results for endotracheal intubation in infants in the past. The CMAC videolaryngoscope has launched its novel infant Miller blade, but its performance has not been assessed clinically for routine intubation in infants and neonates. We hypothesized that the CMAC videolaryngoscope would reduce the total time to intubation as compared to the Truview Picture Capture Device in neonates and infants...

OBJECTIVE: This prospective randomized study aimed to assess the usefulness of two videolaryngoscopes with a side channel, the Airtraq DLTM and the AWS-200TM , for intubation with a double-lumen tube (DLT). METHODS: In 60 patients with an American Society of Anesthesiologists physical status of 1-3 who were not expected to have difficult airway, the Airtraq DLTM and the AWS-200TM were randomly used for DLT intubation. The primary outcome was intubation time. The secondary outcomes included exposure time, the glottis view with the Macintosh and study videolaryngoscopes, the number of attempts before successful intubation, the intubation difficulty scale (IDS) score, and the subjectively rated ease of blade insertion and DLT advancement...

First-pass success rates during intubation of infants in the emergency department have been shown to be low. Video laryngoscopy is being increasingly used during advanced airway management in the emergency department, but available data have not supported improved outcomes with use in pediatrics. The newly available Macintosh size 0 (curved) blade for the C-MAC video laryngoscope offers a narrower blade for use in infants. We describe the use of the new C-MAC Macintosh 0 blade for intubation of 2 infants with apnea secondary to respiratory syncytial virus bronchiolitis...

Tracheal intubation is a critical step in securing the patient's airway in a variety of emergent and non-emergent settings. Difficulties and complications may arise with this procedure, and alternative laryngoscopes that use video technology have been designed to improve visibility when airway difficulty is predicted or encountered. These devices may be flexible or rigid in design for the purpose of assisting in intubations, especially expected difficult intubations. Video laryngoscopes have been advertised as being able to reduce difficulty, failure, trauma and other complications compared with direct laryngoscopy...

We herein report two expected difficult intubation cases that failed with an angulated-type video laryngoscope (C-MAC D-blade) and were rescued with a channelled-type Airtraq® device. The common signs and characteristics which indicated difficult ventilation and intubation in these patients were Mallampati 4 (with phonation), mandibular protrusion of B, obstructive sleep apnoea disorder, male gender, and thick neck (>46 cm). We had aids ready in the operating theatre for the anticipated difficult intubation...

During laryngoscopy, the laryngoscope blade sometimes comes in contact with the teeth, fracturing or dislocating them. However, no studies have compared the effects of newly marketed video laryngoscopes and the Macintosh laryngoscope (Mac) on teeth. In this study, we measured and compared the force exerted on the teeth of an intubating manikin by the Mac, the Airway Scope (Pentax), and the McGrath MAC (Covidien). The mean force exerted was 141.1 ± 15.7 kg by the Mac, 39.2 ± 10.3 kg by the Airway Scope, and 48...

BACKGROUND: Novice clinicians who have little or no clinical experience in tracheal intubation occasionally need a long time to perform the procedure when using a large curved blade. They also have a lower tracheal intubation success rate, especially in emergency situations, such as cardiac arrest, than experienced practitioners. This study aimed to investigate whether the size of the curved laryngoscope blade affects the outcomes of tracheal intubation performed by incoming interns on a manikin model...

Introduction: Intubation can sometimes be difficult in patients with lesions in the mouth floor. Ameloblastoma is a frequently encountered tumor of the maxillofacial area. An extensive lesion might occupy the floor of the mouth, prevent displacement of the tongue, limiting the space for inserting a laryngoscope blade and resulting in difficult intubation even with fiberoptic bronchoscopy. Case presentation: A 66-year-old man (67 kg; 171 cm) with a mental swelling was diagnosed with ameloblastoma and scheduled for surgical resection...
