Regional Anesthesia for Postnephrectomy Pain Clinical Trial
Official title:
Ultrasound- Guided Mid Point Transverse Process to Pleura Block: Does It Decreases the Incidence of Acute and Chronic Post Nephrectomy Pain? Randomized Controlled Study.
Radical nephrectomy is the surgical process for the resection of malignant tumors of the kidney necessitating a subcostal flank incision.Mild to severe pain is observed in the postoperative period Ineffective pain management leads to several complications. The mid point transverse process to pleura block (MTP) , this technique was used for pain relief after mastectomy, thoracic, abdominal, and spinal surgery and was found effective due to its simplicity and lower risks compared to epidural analgesia.
Ineffective pain management leads to several complications including immobilization, thromboembolism, persisting chronic pain, increased opioid consumption, and delayed hospital discharge.[3] Multimodal analgesic (MMA) regimens using several drugs and techniques are considered to be necessary for postoperative pain relief. Regional anesthesia techniques, mainly epidural analgesia and more recently, paravertebral blocks became crucial parts of a MMA regimen after the introduction of ultrasound (US) in the regional anesthesia practice. The mid point transverse process to pleura block (MTP) block was first described as a modified paravertebral block in 2017. The local anesthetic drugs are administered between the transverse process and the pleura. This results in a local anesthetic drugs spread to the dorsal and ventral rami in the paravertebral space through the fenestrations in the superior costotranverse ligament (SCTL) at the level of injection, and frequently to adjacent levels. This technique was used for pain relief after mastectomy, thoracic, abdominal, and spinal surgery and was found effective due to its simplicity and lower risks compared to epidural analgesia. ;
