Primary Outcome Measures :
  1. Pain assessment calculated as the area under the curve of VAS pain intensity scores through 48 hours after surgery [ Time Frame: 1±0.1, 2±0.1, 3±0.1, 4±0.25, 8±0.5, 12±0.5, 16±0.5, 20±0.5, 24±1, 28±1, 32±2, 36±2, 40±2, 44±2, 48±2 h after the surgery ]

Secondary Outcome Measures :
  1. Consumption of ketorolac via intravenous Patient- Controlled Analgesia (IV PCA) [ Time Frame: Day 1-2 ]
  2. Pain assessment measured with VAS during Day 3-7 in the morning and evening, as well as during special events such as bowel movements. [ Time Frame: Day 3-7 ]
  3. Time from the end of operation to the first PCA Ketorolac dose [ Time Frame: From the end of operation until the first PCA ketorolac dose used, assessed up to 48 hrs ]
  4. Brief Pain Inventory (BPI) [ Time Frame: Day 1, 2 and Day 7 ]
  5. Consumption of oral Ketorolac (Day 3-7) [ Time Frame: Day 3-7 ]
  6. Patient satisfaction-Subject will be asked to classify themselves as either: 'highly satisfied', 'satisfied', 'uncertain', 'dissatisfied' or 'very dissatisfied' [ Time Frame: Day 7 ]

  • History of hypersensitivity or allergy to amide-type local anesthetics, opioid, or any ingredient of the medications administered in this study.
  • Subject has a resting respiratory rate less than 8 per minute and blood oxygen saturation less than 90 mmHg.
  • Use of any NSAIDs, selective COX-2 inhibitors, opioid, acetaminophen, selective serotonin reuptake inhibitors (SSRI), tricyclic antidepressants (TCA), gabapentin, or pregabalin within three days of surgery.
  • Chronic use of opioid medications for more than 14 days in the last 3 months, or non-opioid pain medications more than 5 times per week before screening visit.
