Purpose: This study aimed to evaluate the frequency at which postintubation sedation is administered following use of long-acting paralytic agents compared to short-acting paralytic agents during rapid sequence intubation performed in the emergency department. Methods: This retrospective, single-center study of intubated patients in the emergency department analyzed the difference in time to administration of additional sedation following use of a short-acting paralytic (succinylcholine) compared to use of a long-acting paralytic (rocuronium or vecuronium). A total of 387 patients were available for analysis. The primary outcome was additional sedation given within 15 minutes following administration of a paralytic agent. The secondary outcome sought to evaluate the incidence of hyperkalemia due to paralytic agents by comparing potassium level before and after paralytic administration. Results: 46.9% of patients who received a short-acting paralytic agent received additional sedation within 15 minutes, compared to 40.9% of patients who received a long-acting paralytic agent. The Chi-square analysis comparing the short and long-acting paralytic groups showed no statistically significant difference (χ² [1, N = 387] = 1.24, P  = .266) in the frequency of additional sedation administered. Excluding patients who did not receive any additional sedation, the mean time from paralytic administration to additional sedation in all patients was 20.03 ± 18 minutes. No statistically significant difference was detected between groups regarding changes in potassium level. Conclusion: The use of long-acting paralytic agents was not associated with increased time to administration of sedation compared to shortacting paralytic agents. There is an opportunity to reduce the time to sedation administration for intubated patients receiving both short- and long-acting paralytic agents.
