The purpose of this study is to determine whether a multi-modal anesthesia and pain control protocol reduces post-operative and post-discharge nausea and vomiting (PONV and PDNV) in patients undergoing upper jaw corrective surgery.

Condition Intervention
Post-operative Nausea
Post-operative Vomiting
Post-discharge Nausea
Post-discharge Vomiting
Other: Anesthesia and postoperative medication and fluid protocol

Study Type: Interventional
Study Design: Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment

Primary Purpose: Prevention
Official Title: A Prospective Evaluation of an Anesthesia Protocol to Reduce Post-operative and Post-discharge Nausea and Vomiting in a High Risk Orthognathic Surgery Population

Further study details as provided by University of North Carolina, Chapel Hill:

Primary Outcome Measures:
  • Post-operative nausea and vomiting [ Time Frame: End of surgery to discharge from hospital - average 3 days ] [ Designated as safety issue: Yes ]
    End of surgery time determined by anesthesia portion of the medical record. PONV to be assessed by review of surgeons' and nurses' notes in the medical record as well as through review of patient diaries. Vomiting constitutes a safety issue and, as such, associated adverse events will be noted.

Secondary Outcome Measures:
  • Hospital length of stay [ Time Frame: Anesthesia start time to placement of discharge order - average 3 days ] [ Designated as safety issue: No ]
    Anesthesia start time determined from anesthesia portion of the medical record. Time at which discharge order was placed will serve as time of discharge.

  • Post-discharge nausea and vomiting [ Time Frame: 1 week from discharge from hospital ] [ Designated as safety issue: No ]
    To be assessed based on patient diary completed daily for 1 week following discharge to home from the hospital

Estimated Enrollment: 100

Estimated Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Anesthesia and postoperative medication and fluid protocol
    Scopolamine 1.5 milligram(mg) patch for 48 hours(h), Midazolam 1-2mg intravenous(IV) once, Propofol & remifentanil IV for general anesthesia, Neostigmine maximum 2.5mg, 250mg erythromycin by mouth(po) every(q)8h for 2 doses, Solumedrol and Depomedrol dosing per surgeon, 0.625mg IV droperidol and 4mg IV/8mg sublingual(SL) Zofran at end of surgery, nasogastric tube used to empty stomach at end of case then removed, Ketorolac 30mg IV at start of surgery then 15mg IV q6h for 24h. Then ibuprofen 600mg po q6h as needed for pain. Breakthrough pain: Fentanyl IV in recovery room, Hydromorphone IV after leaving recovery room, Hydrocodone/tylenol po. May substitute other opioids if no response. For nausea/vomiting in recovery room: Promethazine 6.25-25mg IV or per rectum(PR); Decadron 4mg IV; or Benadryl 25-50mg IV/po. IV fluids: Total at least 25 milliliters per kilogram (mL/kg)-10mL/kg in OR. For nausea/vomiting after recovery room: 4mg IV or 8mg SL zofran q6h or 6.25-25mg phenergan (IV or PR)
