Background:
The purpose of this study was to evaluate epidurography contrast patterns in fluoroscopically guided cervical interlaminar epidural injections using the midline approach.
Methods:
All epidural injections were performed at the C6-7 level in the prone position. Epidurography was performed using a fixed amount of iotrolan 240 mg I/mL (1, 2, 3 mL).
Results:
The rate of ventral epidural spread was 56.7% in Group A (1 mL), 90% in Group B (2 mL), and 93.3% in Group C (3 mL).
Conclusions:
Two milliliters of contrast solution can provide optimal dispersion of contrast in a ventral and longitudinal spread.

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
