About

The aim of this study is to compare external oblique intercostal plane (EOIP) block and ultrasound guided transversus abdominis plane (TAP) Block for postoperative analgesia in adult patients undergoing open nephrectomy.

Full description

Patients undergoing nephrectomy have a high incidence of postoperative pain despite the use of modern laparoscopic surgical techniques. In the postoperative period, these patients are often treated with patient-controlled opioids, epidural analgesia, or both.

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. Studies have confirmed that ultrasound-guided (USG) transversus abdominis plane (TAP) block is an effective method of analgesia for upper abdominal surgeries, lower abdominal surgeries, and kidney transplantation, with minimal side effects.

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 .
