Intranasal sufentanil for Acute Pain

This study will be a single-center, randomized, controlled trial conducted in the Brooklyn Hospital Center's Emergency Department (ED) expected to last 2 years. The sample size will be 40 patients with 20 patients in each treatment arm. The data points to be collected in the study are as follows: baseline characteristics (baseline pain score, date of birth, age, gender, weight and ethnicity), NRS pain scores at 5, 10, 20, and 30 minutes, dose of study treatment administered, incidence of adverse effects, time to patient discharge following administration of study treatment, patient satisfaction of pain control based on a 10-point Likert Scale, number of patients who required rescue analgesia, and amount of rescue analgesia required. 4. Once informed consent is obtained, patients will be randomized to receive Treatment A (sufentanil 0.7 mcg/kg intranasally (IN) and normal saline 1ml IV push) OR Treatment B (Normal saline 0.6 mL IN and morphine 0.1 mg/kg IV push). It should be noted that during the study period, use of additional morphine or adjuvant analgesics outside of the designated time intervals is allowed. The decision to use adjuvant analgesics is the decision of the attending physician assigned to the patient in the Emergency Department (ED).
