INTRODUCTION: Recent studies have highlighted the use of a video laryngoscope, a promising airway device that enables faster intubation than a Macintosh laryngoscope without the cessation of chest compressions. The aim of this study was to compare the performance of a Pentax AirwayScope (AWS) with that of a laryngeal mask airway (LMA) when utilized by unskilled personnel in a mannequin model while performing chest compressions. METHODS: We conducted a randomized controlled crossover trial to compare the effects of these two airway devices. A total of 36 participants performed intubation on a mannequin, with each device in both common and moderate level of difficulty airway scenarios. The time to successful ventilation, rate of ventilation success, and subjective difficulty in manipulating the devices were compared. RESULTS: In a scenario with airways of common difficulty, the LMA had a shorter time interval to successful ventilation than the AWS (13.6 vs. 25.2 seconds, respectively, p<0.001). In a scenario with moderately difficult airways, the LMA was also shorter than the AWS (14.5 vs. 26.9 seconds, respectively, p<0.001). For every level of difficulty for the airway, the LMA showed a higher successful ventilation rate and a lower extent of difficulty in device operation than the AWS (p<0.05). CONCLUSION: In the pre-hospital setting, using the LMA could enable an unskilled rescuer to establish airway patency more rapidly. LMA might also be safer and easier for operation than the AWS.

Supraglottic airway devices (SADs) have become prevalent in children because they avoid many of the adverse effects associated with endotracheal intubation. The laryngeal mask airway (LMA) Classic and the LMA Proseal have proven safe and efficacious for routine cases in pediatric patients. The LMA Proseal provides a better airway seal and protection against aspiration than the LMA Classic in children. Most SADs are designed for airway maintenance during routine anesthesia, but other roles include rescue airway after failed intubation, conduit to facilitate difficult intubation and as an adjunct device for special situations in or outside the hospital (e.g., neonatal resuscitation). Recently developed second-generation SADs, the i-gel and the LMA Supreme may be a suitable alternative for airway management when a single-use device with gastric access is needed in children. The Air-Q intubating laryngeal airway may be feasible as a conduit for tracheal intubation for pediatric patients with a difficult airway. This review article discusses the safety and efficacy of SADs in children.

Nasotracheal intubation, when performed after craniomaxillofacial trauma, may result in the passage of the tube into the cranium, causing significant brain damage. Orotracheal intubation may be preferred, but interferes with the placement of intermaxillary fixation. To avoid these problems, a tracheostomy may be an alternative but it carries significant morbidity. The submental route for endotracheal intubation has been proposed as an alternative to a tracheostomy in the surgical management of craniomaxillofacial trauma. Ideally, this maneuver is performed by using a reinforced tube. Unfortunately, however, some reinforced tracheal tubes are manufactured with nondetachable connectors. Removing them forcefully may be possible, but they will then stay dangerously loose after reconnection. We report a case in which a standard oral Ring-Adair-Elwyn (RAE) tube and reinforced tube for ILMA was used so not to be loose after the reconnection.

BACKGROUND: Insertion of supraglottic airway devices (SADs) can be technically easier to perform for novices than endotracheal intubation (ETI), particularly in a situation with difficult airway management. We evaluated the efficacy and usefulness of the ProSeal laryngeal mask airway (PLMA), I-gel, and ETI when used by novices in a simulated difficult airway scenario. METHODS: A total of 109 novices participated in a brief educational session about PLMA, I-gel and ETI. The sequence of the airway devices was randomized for each participant using a computer-generated random table, and the devices were inserted in a manikin with restricted cervical spine movement. A nasogastric (NG) tube was then inserted through each SAD. In the case of ETI, the NG tube was inserted through the manikin's nostril. RESULTS: The success rate at the first insertion attempt was 93.6% for the I-gel compared with 72.5% for the PLMA and 19.3% for ETI. The I-gel also enabled a significantly shorter insertion time than the PLMA (I-gel 26.3 ± 21.9 sec and PLMA 36.0 ± 35.4 sec). The novices showed high success rates for NG tube insertion using SADs (PLMA 96.3% and I-gel 98.1%) compared with ETI (24.8%). CONCLUSIONS: We found that the I-gel provided a better first time success rate and a shorter insertion time than PLMA and ETI, which indicated that the I-gel may be preferable for difficult airway management by novices.

The laryngeal mask airway (LMA) is a relatively recent development that fills the gap in airway management between endotracheal incubation and the use of a face mask. The device is inserted blindly into the pharynx, forming a low pressure seal around the laryngeal inlet permitting gentle positive-pressure ventilation. It allows the administration of inhaled anesthetic agents through a minimally stimulating airway. This factor, combined with ease of insertion, makes the laryngeal mask airway an attractive alternative in pediatric patients with difficult airways Flame burns have long term effects that may cause problems such as the development of contractures which eventually lead to inability in performing normal bodily functions. If neglected, these areas can be sites of infectious which further aggravate the situation This case report deals primarily on neglected flame burns with contractures on the neck, axilla, elbows and hands, posing potential problems with endotracheal i The clinical application of the laryngeal mask airway in this situation is elucidated in this report.

Stridor in infants with subglottic cyst is rare. Mismanagement of such cases may lead to respiratory compromise with a potentially serious and fatal outcome. The diversity of the clinical presentations throws a great challenge in the diagnosis of subglottic cysts. Manifestations vary as they depend on the size and location of the cysts. We report the case of a 6-month-old girl who had a subglottic cyst but managed as moderate croup till she developed worsening respiratory acidosis which difficult intubation. Any case of premature infants with previous history of neonatal intubation presenting with stridor should prompt clinicians to look for possible cysts in the larynx. This is important because once the diagnosis is made,appropriate treatment may be given and unnecessary morbidity and mortality may be avoided.

Submental endotracheal intubation is a simple and secure alternative to either nasoendotracheal intubation or a tracheostomy in the airway management of maxillofacial trauma. However, a submental endotracheal intubation is quite difficult to manage if adverse events such as a tube obstruction, accidental extubation, or a leaking cuff with the endotracheal tube in the submental route occur, which could endanger the patient. This paper describes the use of a LMA-Fastrach (TM) ETT in the submental endotracheal intubation of patients suffering from maxillofacial trauma. One of the patients was a 16-year-old male, and the other was a 19-year-old male. They were scheduled for an open reduction and internal fixation of the maxillofacial fracture including naso-orbital-ethmoidal (NOE) complex, and a zygomaticomaxillary complex fracture. A submental intubation with a LMA-Fastrach (TM) ETT was performed in both cases, and the operation proceeded without any difficulties. These cases show that the use of the LMA- Fastrach (TM) ETT can improve the safety and efficacy of submental endotracheal intubation. This is because the LMA- Fastrach (TM) ETT has a freely detachable connector, and is flexible enough to keep the patency despite the acute angle of airway.
