Effects of Epidurally Administered Ropivacaine Concentration on the Hemodynamic Parameters

• Status: Completed
• Trial end date: 2013-04-19

Summary

In this trial, the investigators intend to examine whether the concentration of local anesthetics during epidural analgesia could be modulating factor for change of hemodynamics in patients undergoing major upper abdominal surgery.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Pusan National University Hospital
• Treatments: Anesthetics; Ropivacaine
