Relieving postoperative nephrectomy pain requires multimodal approaches. The most
commonly used in the treatment of pain are nonsteroidal anti-inflammatory drugs (NSAIDs),
opioids, and infiltration of local anesthetics. Due to the side effects of NSAIDs and
opioids, the application of regional analgesia techniques can reduce complications while
providing better analgesia quality. Peripheral blocks such as ESP block and M-TAPA block
and multimodal analgesics reduce side effects by reducing the use of other analgesics.
Pain is considered one of the most important factors affecting the quality of healing.
Postoperative pain delays the postanesthesia care unit, hospital stay, early ambulation,
increases resource utilization, and negatively affects patient satisfaction. If
postoperative analgesia is provided, all these negativities will be eliminated. This
study aimed to compare the effectiveness of erector spinae plane block (ESP block) and
modified thoracoabdominal nerve blocking with perichondrial approach (M-TAPA block) in
postoperative analgesia management in nephrectomy cases.
