Trial Outcomes & Findings for TEA vs. PVB vs. PCA in Liver Resection Surgery (NCT NCT02192879)

NCT ID: NCT02192879

Last Updated: 2016-10-24

Results Overview

Post-operative pain scores at rest, as assessed by Pain Assessment Scales (Wong-Baker Faces Scale and Visual Analog Pain Scale (VAS) will be the primary outcome measured. Pain scores will be collected per standard PACU protocol (every 60 minutes) and on the hospital ward at hours 2, 4, 6 and 12, and then daily until day 3 or when the epidural/paravertebral catheter is removed. Postoperative pain at rest will be defined as the highest VAS pain score reported by each patient at any time. Pain score is from 0 (no hurt) to 10 (hurts worst).

Measure
Thoracic Epidural
thoracic epidural: Thoracic Epidural catheters will be placed between T8-12 interspaces preoperatively. Epidural hydromorphone (200-600mcg) will be given preoperatively. TEA will be dosed intraoperatively with a continuous infusion of 0.25% bupivacaine at 3-6ml per hour. At the end of surgery, infusion will be changed to 0.125% bupivacaine + 10mcg/ml hydromorphone at 4-6ml/hour. In PACU, a PCEA button will given to the patient for bolus dosing of 1-2ml and a lockout of 30 minutes. Changes to the epidural infusion solution, rate, and PCEA bolus dosing will be made clinically as required by the Acute Pain Service (APS).
Continuous Paravertebral Catheter
continuous paravertebral catheter: Bilateral PVB catheters will be placed between the T8-12 interspaces preoperatively. 10ml of 0.5% ropivacaine will be injected into the paravertebral space, then catheter placed. The same procedure will be used for the placement of the PVB catheter on the opposite side. The catheter may be bolused with 5ml 0.5% ropivacaine hourly intraoperatively if needed. In PACU, PVB catheters will be infused continuously with 0.2% ropivacaine at 8-12ml/hr. Subjects will also be given a hydromorphone PCA button to deliver additional IV opioid medication to the patient as needed.
Patient-Controlled Analgesia
Patient-Controlled Analgesia: Intravenous hydromorphone PCA will be initiated postoperatively with dosing prescriptions made by the primary surgical team.
