ReviewAdverse effects of neuromuscular blockers and their antagonists.
Among all the drugs used for general anesthesia, neuromuscular blockers appear to play a prominent role in the incidence of severe adverse reactions. It now seems likely that most serious adverse drug reactions occurring during anesthesia are immunological in type. The frequency of life-threatening anaphylactic or anaphylactoid reactions occurring during anesthesia has been estimated to be between 1 in 1000 and 1 in 25,000 anesthetic procedures, with the neuromuscular blockers being involved in 80% of cases. ⋯ In addition, nondepolarising neuromuscular blockers have been implicated in causing generalised weakness following their long term administration to patients on an intensive care unit. The problem with these adverse drug reactions is their upredictable nature. Therefore, prompt recognition with appropriate therapy can help to improve the outcome.
