BACKGROUND: Negative pressure pulmonary oedema (NPPE) is a potentially life-threatening complication of laryngospasm that occurs during or after general anaesthesia. It is a complication of poorly treated or unrecognized laryngospasm occurring at extubation or later in the postoperative period. OBJECTIVE: To emphasize prompt recognition of laryngospasm during or after general anaesthesia and to...

Laryngospasm is a rare but potentially life-threatening occurrence in infants and usually has infective, allergic, metabolic, or anatomic causes. Underlying genetic conditions are rarely considered. Mutations in SCN4A encoding the voltage-gated sodium channel NaV1.4 have been implicated in a wide spectrum of neuromuscular disorders with variable onset, ranging from a rare form of congenital mya...

Background and Aims: Laryngospasm and vomiting occurring after tracheal extubation in children is potentially dangerous. The aim of this study was to investigate the effects of preoperative 0.5 mg/kg i.v. Dexamethasone on the incidence of postextubation laryngospasm, and vomiting in children after tonsillectomy. Material and Methods : This study was performed at the Ilam Imam Khomeini hospital,...

BACKGROUND AND OBJECTIVES Weaning patients from mechanical ventilation is a challenge in the intensive care unit (ICU) practice and is related to some complications. One of these is the pos-extubation laryngospasm, an event that can be anticipated for the cuff leak test (CLT). The objective was demonstrate that the CLT is a simple, reliable and low costs method to available the presence of obst...

OBJECTIVE The goal of this study was to assess the knowledge of pediatric hospitalists (PHs) in identifying and managing rare events during procedural sedation (PS) with ketamine and nitrous oxide (N2O). METHODS A Web-based survey with multiple choice questions and case scenarios was used to determine the knowledge of PHs in identifying infrequent contraindications and managing laryngospasm, ...

Laryngospasm as a solitary manifestation of epilepsy is rare. It was reported in a girl who had a long history of repeated seizures.3 Nocturnal dyspnoeic attacks in children were described by Jackson and Jackson4 and defined as 'sudden dyspnoeic seizures' but no electroencephalographic correlates were reported. The usual causes oflaryngospasm, hypocalcaemia, hypoparathyroidism, or hypomagnesaem...

L aryngospasm is a common complication of airway management in anesthetic practice (1). It consists of a prolonged glottic closure reflex mediated by the superior laryngeal nerve. It often occurs with insufficient depth of anesthesia on endotracheal intubation, light anesthesia on tracheal extubation, or a combination of either of the preceding with an airway irritant such as blood, mucus, lary...

Laryngospasm is one of the more common forms of airway obstruction encountered by an anesthetist. Therapy usually is straightforward, with resolution of the obstruction normally occurring within minutes. In some cases, however, the patient's vigorous inspiratory efforts may lead to a rapidly deteriorating form of pulmonary edema. Two cases are presented that are quite typical of the development...

We report the case of a 6-month-old child who developed acute pulmonary edema because of laryngeal spasm during orthopedic manipulations for congenital hip dysplasia. Laryngospasm was probably secondary to an unsuspected light level of anesthesia, maintained via face mask. No other predisposing factors, such as enlarged adenoid tonsils, laryngitis, epiglottitis, mechanical stimulation of the la...
