Incidence of insufficient intraoperative neuromuscular paralysis. A retrospective registry analysis.
Muscular tone that inhibits anesthetic or surgical care characterizes insufficient neuromuscular block. The incidence of insufficient neuromuscular block is unknown, therefore we developed novel electronic search strategies to identify occurrences of insufficient neuromuscular block. Our primary goal was to determine the incidence of intraoperative insufficient neuromuscular block in abdominal and neurovascular surgery. Our secondary goal was to assess factors independently associated with insufficient block. ⋯ Our results suggest that episodes of insufficient block occur in over a quarter of operations that are generally thought to require muscle relaxation. Without neuromuscular monitoring, it is difficult to separate inadequate anesthesia from inadequate neuromuscular block, and both presumably contributed in many cases.
