CONTINUOUS ULTRASOUND GUIDED ERECTOR SPINAE PLANE BLOCK IN PEDIATRIC LIVER HYDATID CYST SURGERY.

Background and Objectives: Liver hydatid cyst surgery is considered an extremely painful procedure. Managing pain in this surgery is challenging with several options available, each with limitations. Erector spinae plane block is a novel technique with promising results that have been reported in different types of surgery. Case Report: We are reporting here the continuous ESP block as a primary mode of postoperative analgesia in a 9-year-old-female scheduled for a liver hydatid cyst surgery. After general anesthesia induction, a continuous erector spinae plane block at T6 level was performed with bupivacaine 0.25%. The intraoperative opioid and anesthetic requirement was very less with a good hemodynamic stability as well as long-lasting postoperative analgesia. Conclusion: The ESP block is an effective option for liver hydatid cyst surgery. The opioid- and anesthetic-sparing effects exhibited in this case facilitated rapid postoperative recovery.
