A clinical grading scale to predict malignant hyperthermia susceptibility.

abstract：BACKGROUND:The authors sought to determine whether subjects with pathophysiological conditions that are characterized by increased concentrations of aldosterone have increased susceptibility to the side effects of neonatal anesthesia with sevoflurane. METHODS:Postnatal day 4-20 (P4-P20) rats were exposed to sevofluran...

abstract：BACKGROUND:Propofol (2,6-diisopropylphenol) is one of the most frequently used anesthetic agents. One of the main side effects of propofol is to reduce blood pressure, which is thought to occur by inhibiting the release of catecholamines from sympathetic neurons. Here, the authors hypothesized that propofol-induced hyp...
