简要总结
This is a prospective four-armed unblinded randomized controlled trial to assess four different potential post-operative treatment options for men who undergo a vasectomy. The aims of this study are:
- To determine whether the addition of nonsteroidal anti-inflammatory drugs (NSAIDs) to acetaminophen results in improved pain after vasectomy;
- To determine whether the addition of opioid pain medication to acetaminophen and/or NSAIDs results in improved pain after vasectomy;
- To determine whether the use of NSAIDs for post-operative pain management increases risk of hematoma after vasectomy.
详细描述
The purpose of this study is to evaluate and compare commonly used post-vasectomy pain regimens. Eligible participants will be adult male patients who elect to undergo vasectomy with a urologist at Columbia University Medical Center with no history of kidney or liver disease, chronic pain conditions, or drug abuse. Prospectively enrolled participants will be randomized to one of four study arms, which will differ by post-operative pain regimens as follows:
- Arm 1: 975 mg acetaminophen every 6 hours for the first 48 hours to a maximum of 7 days;
- Arm 2: 975 mg acetaminophen and 600 mg ibuprofen every 6 hours for the first 48 hours to a maximum of 7 days;
- Arm 3: 975 mg acetaminophen every 6 hours for the first 48 hours to a maximum of 7 days with a prescription for 6 tablets of 5 mg oxycodone every 6 hours as needed;
- Arm 4: 975 mg acetaminophen and 600 mg ibuprofen every 6 hours for the first 48 hours to a maximum of 7 days with a prescription for 6 tablets of 5 mg oxycodone every 6 hours as needed.
Other than the differing pain regimens, all treatment and pre- and post-operative counselling will be standard of care at the discretion of the treating urologists. Participants will be contacted at 1 day and 7 days post-operatively to complete Brief Pain Inventory (BPI) questionnaires, assess how many tablets of oxycodone they have taken, and assess whether they would be comfortable returning to work. At post-operative visits, their treating urologist will assess them for the presence of hematoma. Comparisons will be made between study arms to assess for differences.

结局指标
主要结局
Brief Pain Inventory (BPI) - Total Score
时间窗: 1 to 7 days post operatively
The Brief Pain Inventory is a self-reported questionnaire to assess pain. Final scores will be averaged. The score range is 0 to 10, where a higher score indicates a worse outcome.
次要结局
- Brief Pain Inventory (BPI) - Pain Interference Score(1 to 7 days post operatively)
- Brief Pain Inventory (BPI) - Pain Severity Score(1 to 7 days post operatively)
