Study summary

The purpose of this study is to determine if a single dose of sublingual sufentanil is as or more efficacious than a single dose of IV fentanyl in a post anesthesia care setting.

Read the detailed description

This is a level I randomized prospective outcomes study comparing two groups of patients. Upon arrival in the ambulatory surgery center (ASC) post-anesthesia care unit (PACU) if the patient has a pain score of 4 or greater they will then be randomized to one of two groups. Group 1 will receive 50 mcg of IV fentanyl and group 2 will receive 30 mcg of sublingual sufentanil. The primary outcome assessed will be time of readiness to discharge after arrival in the post-anesthesia care unit.

What researchers measure

Primary outcomes

  1. Recovery Room Time

    The time (reported in minutes) from when the patient arrives in the PACU, right after surgery, to the time that all discharge criteria are met.

    Time frame: 1 day

Secondary outcomes

  1. Rescue Milligram Morphine Equivalents (Opioid Use After Intervention Until Discharge)

    All doses of opioid medications administered following initial dosage (sufentanil or fentanyl depending on study arm) will be converted to milligram morphine equivalents and summed for reporting.

    Time frame: 1 day

  2. Adverse Events

    Number of serious adverse events (grades 3, 4, and 5) experienced by each group

    Time frame: 1 day

  3. Postoperative Nausea and Vomiting (PONV)

    Number of participants in each arm who are treated for nausea and/or vomiting.

    Time frame: 1 day

  4. Supplemental Oxygen

    Number of participants in each arm who require supplemental oxygen therapy

    Time frame: 1 day

  5. Overall Benefit of Analgesic Score (OBAS)

    Overall Benefit of Analgesic Score (OBAS) is a 7-item multi-dimensional survey that assesses analgesia benefits. Items are scored on a scale from 0 (minimal) to 4 (maximal). Total score is a sum of the 7 item scores with question 7 scored as 4 minus the patient reported number. Total scores range from 0 to 28 with lower scores representing greater benefit from analgesic therapy.

    Time frame: 1 day
