  Purpose

Current standard of care for post-operative analgesia after breast surgery in CDHA is Tylenol #3® (300 mg acetaminophen, 30 mg codeine, 15 mg caffeine per tablet). We are proposing to test the analgesic efficacy of acetaminophen plus ibuprofen against Tylenol #3® in patients undergoing outpatient breast surgery.

Primary Outcome Measures:
  • VAS Scores. [ Time Frame: mean and daily ] [ Designated as safety issue: No ]
  • maximum VAS scores. [ Time Frame: daily ] [ Designated as safety issue: No ]
  • Likert scores. [ Time Frame: mean daily and final ] [ Designated as safety issue: No ]
  • Patient satisfaction with analgesic regimen. [ Time Frame: day 7 ] [ Designated as safety issue: No ]
  • Treatment failures-inadequate pain relief or inability to tolerate side effects. [ Time Frame: daily ] [ Designated as safety issue: No ]
  • Time to stopping medication. [ Time Frame: day 7 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Total Pain relief (TOTPAR). [ Time Frame: daily ] [ Designated as safety issue: No ]
  • Sum of pain intensity differences (SPID). [ Time Frame: day7 ] [ Designated as safety issue: No ]
  • Amount of medication used. [ Time Frame: day 7 ] [ Designated as safety issue: No ]
  • Incidence of side effects. [ Time Frame: day 7 ] [ Designated as safety issue: No ]
  • Compliance with regimen. [ Time Frame: day 7 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: 1 Drug: acetaminophen plus codeine
capsules four times daily until pain free or for a maximum of seven days
Active Comparator: 2 Drug: acetaminophen plus ibuprofen
capsules four times daily until pain free or for a maximum of seven days

Detailed Description:

Block randomization will be used to randomize patients to one of two combinations. Group A will receive capsules containing 650 mg Acetaminophen plus 400 mg Ibuprofen. Group B will receive capsules containing 600 mg Acetaminophen, 15 mg caffeine and 60 mg codeine. Capsules are placed in identical dossettes containing a seven day supply. Patients are instructed to start taking their medications post-op and continue until they are pain free. All participants are given a series of blank Visual Analogue scales and Likert scales and instructed to record their level of pain intensity and pain relief four times per day for the entire week. Peri-operative pain management will be standardized. Patients will not receive pre-operative analgesics. Intra-operative analgesia will be intravenous opioids as selected by anaesthesiology. No local/regional anaesthesia will be used. Intravenous ketorolac will not be allowed for trial participants. All patients will receive intravenous opioid and anti-emetic if required in PACU. Any patients with peri-operative complications or other problems requiring admission or alternative analgesics will be excluded.
