Study summary

There are extensive gaps in the local data considering pregabalin versus gabapentin as pre-emptive analgesics in patients undergoing orthopedic surgeries under spinal anesthesia. Therefore, the current study was planned with the objective of comparing pregabalin versus gabapentin as pre-emptive analgesics in patients undergoing orthopedic surgeries under spinal anesthesia.

Read the detailed description

Since postoperative pain in orthopedic surgery, whether neuropathic or nociceptive, presents a significant challenge for both surgeons and patients, knowing the more effective gabapentinoid as a pre-emptive analgesic would help clinicians to offer prolonged timing of first rescue analgesia and less opioid consumption.

What researchers measure

Primary outcomes

  1. Pain severity

    The severity of pain was analyzed on the visual analogue scale (VAS), with a lower score labelling the effectiveness of the treatment.

    Time frame: 24 hours

  2. Analgesia duration

    The duration of analgesia was measured from awakening to the need of rescue analgesia, when a pain score was more than 3 on VAS.

    Time frame: 24 hours
