    Abstract:
    OBJECTIVES: Rocuronium and succinylcholine are both commonly used neuromuscular blockers for rapid sequence intubation in the emergency department (ED). The objective of this study was to determine if patients who receive rocuronium are more likely to receive lower doses of postintubation sedatives and analgesics compared with patients who receive succinylcholine. METHODS: This was a retrospective cohort study carried out in a tertiary, academic ED. Consecutive adult patients, who were intubated using etomidate for induction of sedation, were included. Patients were categorized on the basis of whether they received (a) rocuronium or (b) succinylcholine for paralysis. The dosing of postintubation sedative and analgesic infusions were compared 30 min after initiation between the two groups. RESULTS: A total of 254 patients were included in the final analysis (rocuronium=127 and succinylcholine=127). In the overall cohort, 90.2% (n=229) of patients were administered a sedative postintubation in the ED. Most of these patients were initiated on propofol infusions. The mean propofol infusion rate at 30 min was 30±23 mcg/kg/min in the rocuronium group and 42±24 mcg/kg/min in the succinylcholine group (P=0.002). A total of 42.5% of patients (n=108) received an analgesic infusion (all patients received fentanyl). The mean fentanyl infusion rate at 30 min was 0.65±0.55 and 0.86±0.49 mcg/kg/h in the rocuronium and succinylcholine groups, respectively (P=0.041). CONCLUSION: Patients who receive rocuronium are more likely to receive lower doses of sedative and analgesic infusions after intubation. This may place them at risk of being awake under paralysis.
