NCT00938548
First received: July 13, 2009
Last updated: May 17, 2010
Last verified: July 2009
  Purpose

The investigators hypothesize that pregabalin will decrease post-operative pain scores and analgesic use following total mastectomy compared to placebo. The primary outcome will be acute postoperative pain, measured by a verbal numerical rating score (VNRS) and total analgesic consumption during postoperative 48 hours. The secondary outcome will be VNRS at 1 week and 1 month after operation.

Primary Outcome Measures:
  • Pain Scores (Verbal Numerical Rating Scale;VNRS) During Postoperative Hours. [ Time Frame: 1, 6, 24, 48 hour ] [ Designated as safety issue: No ]
    Pain was evaluated using an 11-point verbal numerical rating scale (VNRS). Patients were instructed preoperatively to express their pain on the 0-10 VNRS, where 0 represents no pain at all and 10 represents the worst pain imaginable.

  • Number of Participants With the Indicated Side Effects - Nausea & Vomiting, Sedation, Headache, Dizziness Etc. [ Time Frame: 1, 6, 24, 48 hour ] [ Designated as safety issue: Yes ]
    Nausea and vomiting was graded on a four-point scale, where 0 = no nausea, 1 = mild nausea, 2 = severe nausea requiring antiemetics, and 3 = retching and/ or vomiting. Grades 3 and 4 were grouped together as postoperative nausea and vomiting (PONV) and rescue anti-emetic, metoclopramide 10 mg i.v. was given.


Secondary Outcome Measures:
  • Pain Scores (VNRS) at 1 Week and 1 Month After Operation [ Time Frame: 1 week, 1 month ] [ Designated as safety issue: No ]
    Pain was evaluated using an 11-point verbal numerical rating scale (VNRS). Patients were instructed preoperatively to express their pain on the 0-10 VNRS, where 0 represents no pain at all and 10 represents the worst pain imaginable.
