Randomized Controlled Trial Comparative StudyDesflurane-induced preconditioning has a threshold that is lowered by repetitive application and is mediated by beta 2-adrenergic receptors.
An optimal administration protocol to induce a maximal effect of anesthetic preconditioning has not been evaluated to date. In this study, desflurane preconditioning was characterized with respect to its threshold, dose dependency, and continuous versus repetitive application. Furthermore, the role of beta(2)-adrenergic receptors in anesthetic preconditioning was tested. ⋯ beta(2)-Adrenergic receptors mediate desflurane-induced preconditioning. Desflurane-induced preconditioning has a threshold that can be lowered by repetitive administration.

Comparative StudySubglottic stenosis in children undergoing repair of congenital heart defects.
To examine the incidence of subglottic stenosis in children with congenital heart disease undergoing surgical repair and the contributing factors to such a complication. ⋯ Subglottic stenosis is an uncommon complication in children undergoing surgical repair of congenital heart defects. The most important risk factors are younger age and prolonged postoperative ventilation. Early diagnosis, referral, and intervention resulted in a favorable outcome in most of the authors' patients.
