There is a need to fill this knowledge gap and to answer questions about what types of clinical education and what type of management algorithm result in better outcome. In contrast, results from studies in children with recent URIs have shown that LMA was associated with an increased occurrence of laryngospasm.28,32In a recent, large, prospective study, the incidence of laryngospasm was increased after direct stimulation of the upper airway by both LMA and ETT in comparison with a facemask.5Therefore, LMA may be considered more stimulating than the facemask but certainly less than the ETT.

Muscles involved: lateral cricoarytenoid, thyroarytenoids (both from recurrent laryngeal), crycrothyroid (from external branch of superior laryngeal). This situation has been found to occur in approximately 50% of patients.8The most commonly used muscle relaxant is succinylcholine, but other agents have also been used, including rocuronium and mivacurium.8However, succinylcholine remains the gold standard.4Some authors have suggested the use of a small dose of succinylcholine (0.1 mg/kg) but there is a lack of dose-response study because the study included only three patients.52Therefore, we recommend using IV doses of succinylcholine no less than 0.5 mg/kg.
