Changes of the T-wave on range of spinal blockade after low dose epinephrine administration

摘要

Background: Epidural test solution is administered to confirm the correct positioning of an epidural catheter. Hemodynamic changes after administration of epidural test solution reportedly help confirm intravenous (IV) placement of epidural catheters. The change in T wave amplitude is important for checking intravascular placement of epidural catheters. We examined changes in T wave amplitude according to the level of spinal anesthesia after IV epinephrine administration.
