Residual neuromuscular blockade. Incidence and relevance

Residual neuromuscular block is a major risk factor behind critical events in the immediate postoperative period. Residual weakness due to muscle relaxants is seen in more than thirds of postoperative patients with ventilatory failure and hypoxia. Residual neuromuscular block should therefore be regarded as a serious adverse event in the same way as we regard ventilatory depression due to opioids and anaesthetic agents. This presentation aim to clarify our present knowledge and shortcomings in the field of residual neuromuscular blockade.
