BackgroundThis study was done to determine the safety, efficacy, dosing requirements, and spontaneous recovery profiles of prolonged infusions of rocuronium bromide in the critically ill.MethodsThis multicenter, prospective, nonrandomized, open label trial enrolled 32 patients at two university-based medical centers. Patients who were determined to require neuromuscular blockade for at least 24 hours received a bolus of 0.6 mg/kg of rocuronium. After subsequent recovery of two responses (T2) to the TOF stimulation, an infusion of rocuronium was begun at 10 microg/kg/min and continued for 24 to 120 hours as required by the patients' clinical status.ResultsPatients were divided into multiple organ failure (MOF) and non-multiple organ failure (non-MOF) groups on enrollment. The mean infusion rates for the MOF and non-MOF groups were 0.2 and 0.5 mg/kg/hour, respectively.ConclusionThe mean infusion rate of rocuronium that provides approximately 90% blockade is less for critically ill patients with MOF. Spontaneous recovery was prolonged in patients with MOF.
