Efficacy of Ultrasound-Guided Erector Spinae Block for Postoperative Pain Management in Nephrectomy

This clinical trial aims to evaluate the effectiveness of the ultrasound-guided erector spinae plane (ESP) block in managing postoperative pain for patients undergoing open nephrectomy (kidney removal surgery). The study will compare this new technique to traditional pain management methods, such as opioid medications, to assess whether the ESP block reduces pain and the need for opioids after surgery. Patients will be randomly assigned to one of two groups: Group C will receive conventional pain relief methods, including opioids. Group E will receive the ultrasound-guided ESP block in addition to general anesthesia. The main goals are to determine: How much pain relief each method provides, measured using a visual analog scale (VAS). The total amount of opioids required during the first 24 hours post-surgery. Additional measurements will include monitoring vital signs like heart rate, blood pressure, and oxygen levels. This study will help find safer and more effective ways to manage pain after nephrectomy, reducing the reliance on opioids and improving patient recovery
