Post-operative Pain Control of Testicular Sperm Extraction Using Liposomal Bupivacaine

The study is a drug trial comparing the post-operative pain control provided by liposomal bupivacaine (a local anesthetic) against standard bupivacaine (a different formulation of the local anesthetic) for men undergoing testicular sperm extraction.

Treatment and study plan

Liposomal bupivacaine

Drug

After surgical sperm retrieval, the wound will be injected with liposomal bupivacaine (266 mg) mixed with standard bupivacaine (bupivacaine hydrochloride 50mg) for post-operative pain relief.

Standard Bupivacaine

Drug

After surgical sperm retrieval, the wound will be injected only with standard bupivacaine (bupivacaine hydrochloride 100mg) for post-operative pain relief.

Primary outcomes

  1. Pain Scores 48 Hours After Surgery

    Time frame: First 48 hours after surgery

    Every 8 hours in the first 48 hours post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

    Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 480 (maximum pain (score of 10) reported each time across 48 hours).

Secondary outcomes

  1. Pain Scores 60 Hours After Surgery

    Time frame: First 60 hours after surgery

    Every 12 hours in the first 60 hours post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

    Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 600 (maximum pain (score of 10) reported each time across 60 hours).

  2. Pain Scores 7 Days After Surgery

    Time frame: First 7 days after surgery

    Every 12 hours in the first 7 days post-surgery, subjects were prompted to report their pain score on the 11-point numerical pain rating scale, NRS-11 (Numerical Rating Scale, 11 points). 0 indicates no pain and 10 indicates worst possible pain.

    Each subject's pain scores were then plotted against time, and the area under the curve was then computed. The minimum composite score would be 0 (no pain ever reported), and the maximum composite score would be 1680 (maximum pain (score of 10) reported each time across 168 hours).

  3. Narcotic Requirement

    Time frame: First 7 days after surgery

    Total number of narcotic tablets required between the intervention and control arms during post-operative day 1 through 7.

  4. Time to Narcotic Rescue

    Time frame: First 7 days after surgery

    Time (in hours) to first rescue narcotic utilization between the two arms.

  5. Pain Control Satisfaction

    Time frame: 7th day after surgery

    Overall satisfaction of pain control regimen self reported on post-operative day 7. The prompt required a yes/no answer. The percent of participants answering "yes" will be compared between the two arms.

  6. Percentage of Patients Not Requiring Any Narcotics

    Time frame: 7th day after surgery

    The percentage of patients remaining opiate free by post-operative day 7.
