Transversus Abdominis Plane Block Versus External Oblique Intercostal Plane Block for Postoperative Analgesia in Pediatrics Undergoing Open Nephrectomy

Ultrasound Guided Transversus Abdominis Plane Block Versus External Oblique Intercostal Plane Block for Postoperative Analgesia in Pediatrics Undergoing Open Nephrectomy

The aim of this study is to compare the ultrasound guided TAP Block and EOIP block for postoperative analgesia in pediatrics undergoing open nephrectomy.

Nephrectomy in children may also be for malignant conditions of the kidney and adrenal glands. The major indications for nephrectomy vary in different parts of the world and in different age groups and sexes with some recording more benign conditions and others more of malignancies Ultrasound-guided transversus abdominis plane (TAP) block is a relatively new technique to infiltrate regional anesthesia in which local routine anesthetics are injected between the internal oblique and transverse abdominal muscles. The purpose is to provide analgesia to the parietal peritoneum as well as the skin and muscles of the anterior abdominal wall.

External oblique intercostal plane block (EOIPB) has been reported by Elsharkawy et al. in 2021 as a significant modification of fascial plane blocks in that it may engage the upper lateral abdominal walls consistently. In comparison to quadratus lumborum block (QLB) and erector spinae plane block (ESPB) , The advantage of EOIPB is that it may be performed with the patient supine. Furthermore, in comparison to serratus intercostal plane block (SIPB), it generates more extensive analgesic effects throughout the whole midline of the abdomen .
