NCT02642718

Brief Summary

Background: Experimental models using short duration noxious stimuli have led to the concept of pre-emptive analgesia. Ketorolac, a non-steroidal anti-inflammatory drug (NSAID), has been shown to have a post-operative narcotic sparing effect when given pre-operatively and alternatively to not have this effect. This study was undertaken to determine whether a single intravenous dose of ketorolac would result in decreased post-operative pain and narcotic requirements. Methods: In a double-blind, randomized controlled trial, 48 women undergoing abdominal hysterectomy were studied. Patients in the ketorolac group received 30 mg of intravenous ketorolac 30 minutes before surgical incision, while the control group received normal saline. The post-operative analgesia was performed with a continuous infusion of tramadol at 12 mg/hour with the possibility of a 10 mg bolus every 10 minutes. Pain was assessed using the Visual Analog Scale (VAS), tramadol consumption and hemodynamic parameters at 0, 1, 2, 4, 8, 12, 16 and 24 hours post-operatively. We quantified times to rescue analgesic (morphine), adverse effects and patient satisfaction.

  • Pain as measured by the Visual Analog Scale (VAS) score

    The VAS represents a scale with the lowest value as 0 (no pain) and the highest value as 10 (worst imaginable pain).

    at 1 hour postoperatively

  • Pain as measured by the Visual Analog Scale (VAS) score

    The VAS represents a scale with the lowest value as 0 (no pain) and the highest value as 10 (worst imaginable pain).

    at 2 hours postoperatively

  • Pain as measured by the Visual Analog Scale (VAS) score

    The VAS represents a scale with the lowest value as 0 (no pain) and the highest value as 10 (worst imaginable pain).

    at 4 hours postoperatively

  • Pain as measured by the Visual Analog Scale (VAS) score

    The VAS represents a scale with the lowest value as 0 (no pain) and the highest value as 10 (worst imaginable pain).

    at 8 hours postoperatively

  • Pain as measured by the Visual Analog Scale (VAS) score

    The VAS represents a scale with the lowest value as 0 (no pain) and the highest value as 10 (worst imaginable pain).
