Outcome Measures

Primary Outcomes (2)

  • The Numerical Rating Scale (NRS)

    NRS was assessed pain intensity, ranging from 0 (no pain) to 10 (worst pain imaginable).higher scores, higher pain.

    the first 72 hours after the surgery

  • Brief Pain Inventory (BPI)

    The patients answered or pointed their pain on 0-to-10 scales (0=no pain, 10=extreme pain) at the time of responding to the BPI(current pain), and also at the items of "the most severe pain", "the least pain", and "the average pain" in the last 24 hours. Using the BPI, patients were also asked to rate pain-related interference in daily activities, including general activity, mood, walking ability, normal work, relations with other people, sleeping, and enjoyment of life. The anchor points, in each items of interference scale, were 11-point NRSs (0=no interference, 10=interferes completely).

    the first 72 hours after the surgery
