Study Description

Open surgery remains one of the procedures used for those patients requiring partial or radical nephrectomy and is associated with a high incidence of severe immediate postoperative pain and chronic pain the months following surgery.

Regional anesthesia techniques are frequently recommended for pain control in open nephrectomy as they decrease the need for parenteral opioid and improve patient satisfaction.

Although abdominal wall blocks are known to decrease opioid requirements without causing epidural associated hypotension, their role in flank surgeries has been less well-established. The dermatomes that need to be covered in flank incision are T9 to T11.

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.

The external oblique intercostal (EOI) block is a novel method providing simple and effective somatic analgesia to the upper abdomen with minimal side effects. Other advantages include easy sonoanatomy (even in obese patients), being performed in the supine position, and no anticoagulation concern
