OBJECTIVES/HYPOTHESIS To evaluate and describe airway complications in pediatric adenotonsillectomy. STUDY DESIGN Retrospective case-control study. METHODS A chart review of patients that underwent adenotonsillectomy between 2006 and 2010 was performed. Perioperative complications, patient characteristics, and surgeon and anesthesia technique were recorded. RESULTS A total of 682 charts w...

BACKGROUND The modifying effects of fentanyl on protective airway reflexes have not been characterized in children. The aim of this study was to assess the impact of increasing doses of fentanyl on laryngeal reflex responses in children anesthetized with sevoflurane. The authors hypothesized that the incidence of laryngospasm evoked by laryngeal stimulation is reduced with increasing doses of f...

BACKGROUND Either controlled ventilation or spontaneous respiration is commonly used in general anesthesia for inhaled foreign body removal via rigid bronchoscopy. Controversy in the literature exists concerning which form of ventilation is optimally suited for bronchoscopy. We performed a meta-analysis to compare controlled ventilation and spontaneous respiration with respect to complications,...

Laryngospasm and apnoea or alterations in the rhythm of respiration have been produced in decerebrate preparations of cats and in cats anaesthetized with chloralose during the start of inhalation of volatile anaesthetic agents. Ether, halothane and methoxyflurane all produced these effects when they were placed in contact with the larynx. The responses to ether occurred more rapidly than those ...

Mutations of SCN4A encoding the skeletal muscle sodium channel Nav 1.4 cause several types of disease, including sodium channel myotonias. The latter may be responsible for neonatal symptoms, including severe neonatal episodic laryngospasm (SNEL). Establishing the diagnosis of SCN4A-related SNEL early in the neonatal period is crucial because treatment is available that can reduce laryngospasm ...

Laryngospasm (LEP) is defined as the sustained closure of the vocal cords. It is a primitive protective airway reflex (VA), which occurs to safeguard the integrity of the airway by protecting it from tracheobronchial aspiration [1]. LEP is also defined as an exaggerated response to closure reflex or glottic muscle spasm. Essentially it is a protective reflex, which acts to prevent the entry of ...
