Summary

Epidural anesthesia is a widely used method for pain relief which is useful in various settings. Identification of needle entry into the epidural space (EDS) is performed most using a loss of resistance (LOR) technique, which was described in 1921 by Sicard and Forestier, and has remained largely unchanged since. Hysterectomy operations anesthesia and analgesia rely heavily on proper needle placement technique. A noninvasive approach to confirm the correct position of the epidural needle prior to injection of local anesthetics into the epidural space, would thus be beneficial. Ultrasound (US) is a noninvasive approach increasingly used in anesthesia practice. The use of color flow Doppler (CFD) may further aid in defining the epidural space. The aim of current study is to detect and confirm site of epidural catheter in hysterectomy by using color flow doppler ultrasonography.

Conditions

  • Uterine Diseases

Interventions

DRUG

Normal Saline Flush

Five milliliters of sterile saline will be administered as a flush through the needle while recording the color flow doppler images. The same procedure will be repeated with a slow injection of 5 mL of saline. The speed of injection will not be standardized.

DEVICE

Doppler

All color flow Doppler images will be performed with a Phillips CX50 ultrasound machine using a 5.0 MHz a low frequency curvilinear US probe. A two-dimensional transverse interspinous view was used to visualize the posterior complex (ligamentum flavum, epidural space and dura). After loss of resistance to normal saline, the color flow Doppler function will be turned on to examine flow through the epidural needle tip. The ultrasound probe was positioned in the transverse axis slightly below the epidural needle but still in the interspinous space .
