NCT03715517

Brief Summary

This project proposes to compare epidural versus spinal anesthesia in patients having liver resection surgery. The investigators hypothesize that spinal anesthesia will result in improved blood pressure control postoperatively and reduce the amount of intravenous fluids required after surgery. Spinal anesthesia is expected to provide the same pain control benefits as epidurals, with faster recovery of function. Spinal anesthesia may be a simple and effective way to improve and enhance the recovery in the increasing number of patients requiring liver resection.

Outcome Measures

Primary Outcomes (3)

  • Cumulative 72-hour volume of intravenous fluids and blood products administered

    Intraoperative plus cumulative postoperative intravenous (IV) fluid volume administered, total (mL) = sum of volumes of IV crystalloid, IV colloid, and non-albumin blood products (packed red blood cells \[pRBC\], fresh-frozen plasma \[FFP\], and platelets) administered

    Intraoperatively and during the first 72 hours postoperatively or until hospital discharge, whichever occurs earlier

  • Area under the curve over 72 hours of the summed pain intensity difference scores at rest (AUC-SPID-PAR_0-72h)

    Numerical Rating Scale (NRS) Summed Pain Intensity Difference at rest (SPID-PAR) (calculated as Area Under the Curve \[AUC\] using the trapezoidal rule) over 0 to 72 hours (AUC-SPID-PAR\_0-72h) after surgery. Pain intensity (PI) is assessed preoperatively and at 2, 6-12, 24, 36, 48, 60, and 72 hours after surgery or until hospital discharge, whichever came first, using the 11-point Numerical Rating Scale (NRS) on a scale from 0 to 10, where 0 represents the absence of pain and 10 is the "worst possible pain". Pain intensity difference (PID\_t) is calculated as the difference in pain intensity from time 0 to each time point t. SPID\_t is calculated using the trapezoidal rule as the area under the curve (AUC) for Pain Intensity Difference over the time interval 0 to t hours, respectively, divided by the length of the time interval (t hours). A positive value is a decrease (improvement) of the pain.

    72 hours after surgery or until hospital discharge, whichever occurs earlier

  • Cumulative 72-hour opioid consumption (OC_0-72h)

    Total perioperative epidural, intravenous, and oral opioid requirements measured in oral morphine equivalents (OME, mg).

    Intraoperatively and during the first 72 hours postoperatively or until hospital discharge, whichever occurs earlier

Secondary Outcomes (23)

  • Vasopressor-free days to day 30

    During index hospital admission (censored at the earliest of hospital discharge, in-hospital death, or 30 days postoperatively)

  • Cumulative intraoperative vasopressor and/or inotrope consumption

    Intraoperatively (from anesthesia start time to anesthesia end time)

  • Cumulative perioperative vasopressor and/or inotrope consumption

    Intraoperatively and during the first 7 days after surgery or until hospital discharge, whichever occurs earlier

  • Cumulative 72-hour volume of intravenous fluids administered

    Intraoperatively and during the first 72 hours postoperatively

  • Area under the curve over 72 hours of the summed pain intensity difference scores of movement-evoked pain (MEP) (AUC-SPID-MEP_0-72h)

    72 hours after surgery or until hospital discharge, whichever occurs earlier

  • +18 more secondary outcomes

Other Outcomes (6)

  • Cumulative 24-hour volume of intravenous fluids and blood products administered

    Intraoperatively and during the first 24 hours postoperatively

  • Area under the curve (AUC) over 24 hours of the summed pain intensity difference (SPID) scores at rest (AUC-SPID-PAR_0-24h)

    24 hours after surgery

  • Cumulative 24-hour (IV) opioid consumption (OC_0-24h)

    Intraoperatively and during the first 24 hours postoperatively or until hospital discharge, whichever occurs earlier

  • +3 more other outcomes
