Comparative StudyThe severity of sevoflurane-induced malignant hyperthermia.
Malignant hyperthermia (MH) is a potentially fatal complication of general anesthesia triggered by volatile anesthetics. In animal studies, sevoflurane has been reported to be a weak triggering agent. The aim of this study was to evaluate the clinical severity of sevoflurane-induced MH compared to isoflurane. ⋯ There were no clinically apparent differences between MH triggered by sevoflurane and isoflurane, and thus no evidence to support the postulate that sevoflurane is a weak or weaker MH triggering agent.

The saphenous nerve and its relationship to the nerve to the vastus medialis in and around the adductor canal: an anatomical study.
Recently, ultrasound-guided saphenous nerve blocks within and distal to the adductor canal have shown success. However, a potential side effect is an unintentional block of branches of the nerve to the vastus medialis resulting in undesired motor weakness. ⋯ Knowledge of this anatomy may help establish a safe region in preventing motor blockade when performing saphenous nerve blocks.
