Postoperative Belladonna and Morphine Suppositories in Vaginal Surgery
Study Details
Study Description
Brief Summary
Our primary aim is to determine whether the routine use of belladonna and morphine suppositories will improve pain control following vaginal surgery. Treatment will begin immediately following surgery and every 8 hours for 16 hours.

Phase 4 |
Detailed Description
Minimizing postoperative pain is vital to a successful surgical recovery. Inadequate pain control may result in nausea, vomiting, an extended hospital stay, and reduced patient satisfaction. Oral and parenteral narcotics are commonly used for pain relief and their use may exacerbate the incidence of sedation, nausea, and vomiting; ultimately delaying convalescence. Previous studies have demonstrated that rectal analgesia following surgery results in lower pain scores and less intravenous morphine consumption. Belladonna and opium suppositories are routinely prescribed at our institution and their efficacy has not been confirmed.
A prospective, randomized, double-blind, placebo-controlled trial will be undertaken using belladonna and opium rectal suppositories following vaginal surgery. Treatment will begin immediately following surgery and continue every 8 hours for a total of 3 doses.

Outcome Measures
Primary Outcome Measures
- Pain at Hour 4 [4 hours following surgery]
Pain at 4 hours was recorded using a linear analog pain scale, with 0 being "no pain," and 10 being "worst pain imaginable."
Secondary Outcome Measures
- Pain at Hour 12 [12 hours after surgery.]
Pain at 12 hours was recorded using a linear analog pain scale, with 0 being "no pain," and 10 being "worst pain imaginable."
- Pain at Hour 20 [20 hours after surgery.]
Pain at 20 hours was recorded using a linear analog pain scale, with 0 being "no pain," and 10 being "worst pain imaginable."
- Narcotic Rescue Medication [For 24 hours following surgery]
Use of all ancillary narcotic medications was taken from the medical record.
- Number of Subjects With Nausea [Approximately 12 hours after surgery]
This information was taken from the medical record.
- Number of Subjects With Vomiting [Within 20 hours of surgery]
This information was taken from the medical record.
- Number of Times Antiemetic Rescue Medication Was Used [First 24 hours after surgery]
- Number of Subjects Who Used Antiemetic Rescue Medications [First 24 hours after surgery]
- Satisfaction With Pain Relief [Approximately 24 hours following surgery]
Patient satisfaction with pain relief was evaluated 24 hours after surgery using a linear analog satisfaction scale, with 0 being "very dissatisfied," and 10 being "very satisfied."
