Brief Summary

The postoperative pain after open nephrectomy remains a major concern because some patients still demonstrate acute pain that may develop chronic pain that lasts for months following the surgery. Epidural analgesia is the gold standard for abdominal surgery including for open nephrectomy, however, it has unfavorable side effects such as paresthesia, hypotension, hematomas, an impaired motor of lower limbs and urinary retention that could delay recovery. Various techniques have tried to replicate the analgesic efficacy of epidural analgesia. They include transversus abdominis plane analgesia (TAP), rectus sheath analgesia (RS), wound infusion analgesia (WI) and transmuscular quadratus lumborum (TQL) analgesia. However, each of these techniques has specific limitations that prevent them from being the analgesic technique of choice for all open abdominal surgeries. Up to the investigator's knowledge, there is no study done to compare ESPB versus QLB as pre-emptive analgesia in patients undergoing open nephrectomy.

Outcome Measures

Primary Outcomes (1)

  • The 1st time to rescue analgesic

    the time to ask for postoperative analgesia is the time from the end of operation to patient reporting VAS ≥ 3.

    recorded within the first 24 hour postoperatively

Secondary Outcomes (2)

  • Visual analogue scale (VAS)

    measured at at 1 hour, 2,4,,8,12,18, 24 hour postoperatively

  • Total dose of rescue analgesia (morphine)

    in the first 24 hour postoperatively.
