Brief Summary

Moderate to severe postoperative pain often influence patients quality of recovery after hepatectomy. Systemic opioids given with patient-controlled analgesia has been used after hepatectomy in many medical center, but the analgesic effect can be limited and undesirable side effects may bring about negative effects on patients recovery. Regional block has been proved to improve patients postoperative recovery in many kinds of surgeries. The investigators therefore designed a prospective, randomized, subject and assessor blinded, parallel-group, placebo controlled study to test the hypothesis that continuous right thoracic paravertebral block increase patients quality of recovery score on the 7th postoperative day after hepatectomy in patients receiving i.v. patient-controlled analgesia (PCA) with morphine.

Outcome Measures

Primary Outcomes (1)

  • the postoperative recovery quality on postoperative day 7

    The postoperative recovery quality is evaluated with QoR-15 questionnaire. The QoR-15 is a 15-item questionnaire intended to measure QoR after anesthesia and surgery. It comprises five subscales: pain (2 items), physical comfort (5 items), physical independence (2 items), psychological support (2 items), and emotional state (4 items) \[2 Stark PA, Myles PS, Burke JA. Development and psychometric evaluation of a postoperative quality of recovery score: the QoR- 15. Anesthesiology. 2013;118(6):1332.\]. Each item is scored from 0 to 10, and the possible total score ranges from 0(extremely poor quality of recovery) to 150 (excellent quality of re covery).

    at the 7th postoperative day

Secondary Outcomes (6)

  • The pain scores determined by the numeric rating scale (NRS, 0-10)

    At 8, 24,48 hours after the surgery

  • cumulated morphine consumption

    At 8, 24,48 hours after the surgery

  • post operative length of stay

    Up to 2 weeks

  • time to out-of bed activity/ambutation

    Up to 2 weeks

  • time to resumption of bowel movement

    Up to 2 weeks after surgery

  • +1 more secondary outcomes
