laryngal mask

Mosarrat J Qureshi, Manoj Kumar
BACKGROUND: Providing effective positive pressure ventilation is considered to be the single most important component of successful neonatal resuscitation. Ventilation is frequently initiated manually with bag and face mask (BMV) followed by endotracheal intubation if respiratory depression continues. These techniques may be difficult to perform successfully resulting in prolonged resuscitation or neonatal asphyxia. The laryngeal mask airway (LMA) may achieve initial ventilation and successful resuscitation faster than a bag-mask device or endotracheal intubation...

OBJECTIVES: Airway management during adenoidectomy is traditionally performed through endotracheal intubation (ETT). Laryngeal mask airway (LMA) may be less stimulating to the airway and allow for shorter overall operating room time. Previous studies report LMA use during adenotonsillectomy. There has been no prior evaluation of LMA use during adenoidectomy alone. In this study, we attempt to identify the rate and contributing factors of LMA failure during adenoidectomy. METHODS: All pediatric patients undergoing adenoidectomy between January 1, 2016 and June 30, 2017 were reviewed...

OBJECTIVES: Airway management during adenoidectomy is traditionally performed through endotracheal intubation (ETT). Laryngeal mask airway (LMA) may be less stimulating to the airway and allow for shorter overall operating room time. Previous studies report LMA use during adenotonsillectomy with conversion rates to ETT of up to 17%. There has been no prior evaluation of LMA use during adenoidectomy alone. In this study, we attempt to identify the rate and contributing factors of LMA failure during adenoidectomy...

Adverse events following surgical operations are common complications due to removal of tracheal tube in contrast to the tracheal intubation. Awareness about the new methods and strategies for tracheal tube extubation is necessary for a safe and successful extubation. Therefore, we aimed to assess the safety and efficacy of laryngeal mask airway (LMA), streamlined liner of the pharyngeal airway (SLIPA) and I-gel in extubation time of tracheal tube. A one-single randomized clinical trial was conducted in 105 eligible patients in three groups including LMA, SLIPA and I-gel...

Background and Aims: Head and neck movements alter the shape of the pharynx, resulting in changes in the oropharyngeal leaking pressures and ventilation with supragottic airway devices. We compared the effect of the different head-and-neck positions on the oropharyngeal leak pressures and ventilation with the I-Gel™ and ProSeal™ laryngeal mask airway (PLMA) in anaesthetised paralysed children. Methods: A total of 70 children were randomly assigned to receive PLMA ( n = 35) or I-Gel™ ( n = 35) for airway management...

BACKGROUND: Laryngeal mask airways (LMA) are widely used during tonsillectomies. Contrasting evidence exists regarding the timing of the removal and the risk of perioperative respiratory adverse events. We assessed whether the likelihood of perioperative respiratory adverse events is influenced by the timing of LMA removal in children with at least one risk factor for these events. METHODS: Participants (n=290, 0-16 yr) were randomised to have their LMA removed either deep (in theatre by anaesthetist at end-tidal sevoflurane >1 minimum alveolar concentration) or awake (in theatre by anaesthetist or in postanaesthesia care unit by anaesthetist or trained nurse)...

Several mutations in the gene encoding apolipoprotein AI (apoAI) have been described as a cause of familial amyloidosis. Individuals with apoAI-derived (AApoAI) amyloidosis frequently manifest with liver, kidney, laryngeal, skin and myocardial involvement. Although primary hypogonadism (PH) is considered almost pathognomonic of this disease, until now, primary adrenal insufficiency (PAI) has not been described as a common clinical feature. Here, we report the first kindred with AApoAI amyloidosis in which PAI is well-documented...

Background: Several studies have identified side effects of general anesthesia with endotracheal intubation, such as laryngeal pain, dysphonia, and postoperative nausea and vomiting (PONV). The laryngeal mask airway (LMAw) is believed to decrease these side effects. The aim of this trial was to compare postoperative discomfort, emergence delirium, and recovery time of patients who received either an LMAw or nasotracheal intubation (NTI). Patients and methods: A total of 70 children were randomly assigned to the LMAw group (n=35) or the NTI group (n=35)...
