Study summary

Relieving postoperative nephrectomy pain requires multimodal approaches. Peripheral blocks such as ESP block and M-TAPA block and multimodal analgesics reduce side effects by reducing the use of other analgesics. 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.

Read the detailed description

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.

Groups and cohorts

  • M-TAPA Block

    Patients who have standard anesthesia are randomized with the research randomizer application while under anesthesia and M-TAPA block is applied under ultrasound guidance in the preoperative period. For the block, 50 mg of 0.25% bupivacaine and 100 mg lidocaine are injected, totaling 20cc.

    Other: NRS 0. hour · Other: NRS 6. Hour · Other: NRS 12. Hour · Other: NRS 24. Hour

  • ESP Block

    Patients who have standard anesthesia are randomized with the research randomizer application while under anesthesia and ESP block is applied under ultrasound guidance in the preoperative period. For the block, 50 mg of 0.25% bupivacaine and 100 mg lidocaine are injected, totaling 20cc.

What researchers measure

Primary outcomes

  1. Postoperative Pain Management

    The primary outcome of this study is to demonstrate that Modified Thoracoabdominal Nerves Block(M-TAPA) contributes sufficiently to multimodal analgesia in perioperative analgesia in nephrectomy surgery.This contribution will be evaluated with the NRS. NRS is a unidimensional scale in which 11 numbers (between 0 and 10) are used to measure pain intensity. The patient is asked to choose the number that best reflects the pain intensity, with 0 = no pain and 10 = worst (unbearable) pain.

    Time frame: 0.hour

  2. Postoperative Pain Management

NRS is a unidimensional scale in which 11 numbers (between 0 and 10) are used to measure pain intensity. The patient is asked to choose the number that best reflects the pain intensity, with 0 = no pain and 10 = worst (unbearable) pain.
