Pilot Study: Paravertebral Analgesia vs Epidural Analgesia After Thoracotomy

Phase 3
Terminated
Conditions
Hypotension
Interventions
Drug: Epidural Catheter 0.2% ropivacaine
Drug: Paravertebral Catheter 0.4% ropivacaine
Registration Number
NCT01700491
Lead Sponsor
University of Manitoba
Brief Summary

Paravertebral analgesia is non-inferior to epidural analgesia for pain control and superior to epidural analgesia in terms of the main complication of hypotension.

Detailed Description

There is some evidence that paravertebral analgesia is similar to epidural analgesia in efficacy but superior in maintenance of blood pressure. This is a double blind, randomized control trial comparing paravertebral catheters to epidural catheters for the management of post thoracotomy analgesia. Both groups will undergo placement of a pre-induction epidural catheter as well as a surgically placed paravertebral catheter. Patients will also receive PCA morphine. The primary outcome will be daily morphine use measured in milligrams. The co-primary outcome will be time spent with a systolic blood pressure below 90mmHg. Outcomes will be measured during the first five postoperative days.

Epidural Catheter 0.2% ropivacaineEpidural Catheter 0.2% ropivacainePatients will receive an infusion of 0.2% ropivacaine at a range of 0-10 mL/hr through an epidural catheter. They will also receive an infusion of saline at a rate of 0-10 mL/hr through a paravertebral catheter.
Paravertebral Catheter 0.4% ropivacaineParavertebral Catheter 0.4% ropivacainePatients will receive an infusion of 0.4% ropivacaine at a range of 0-10mL/hr through a paravertebral catheter. They will also receive an infusion of saline at a range of 0-10mL/hr through an epidural catheter.
