| Key points NMBDs are now less frequently required to manage the critically ill patient. Neuromuscular block should be monitored if relaxants are used in these patients. Succinylcholine can cause cardiac arrest from hyperkalaemia in the critically ill. Repeated doses or infusions of neuromuscular blocking agents can cause prolonged muscle weakness in patients who are artificially ventilated for several days.

Neuromuscular blocking drugs (NMBDs) are now used less frequently in critically ill patients than they were 15 years ago, mainly because of improved techniques of artificial ventilation.1 Some indications for their use are given in Table 1.2 It is inappropriate to extrapolate experience with the use of NMBDs in the operating theatre in healthy patients to the management of the critically ill. These sick patients often have multiple organ failure and are receiving concomitant medications. The pharmacokinetic and pharmacodynamic properties of NMBDs in this population are poorly understood.
