Ultrasound-Guided Erector Spinae Plane Block to Improve Pain Relief After Open Kidney Surgery A Randomized Study Comparing ESP Block to Standard Pain Treatments

What this Trial Is About

Researchers are evaluating the ultrasound-guided erector spinae plane ESP block as a method to manage postoperative pain in adults undergoing open nephrectomy, which is kidney removal surgery. This trial compares the ESP block to traditional pain relief methods such as opioids to see if it can reduce pain and lower opioid use after surgery. The study involves 66 adult patients and aims to improve recovery by finding safer pain management options. Participants are randomly assigned to one of two groups. The control group receives general anesthesia with conventional pain management including opioids and standard local anesthetics. The intervention group receives general anesthesia plus the ultrasound-guided ESP block, administered before anesthesia induction. The ESP block involves injecting a local anesthetic into the erector spinae muscle area using ultrasound guidance to target pain relief. During the study, researchers will measure pain using the Visual Analogue Scale VAS at multiple time points within the first 24 hours after surgery. They will also track total opioid use, heart rate, blood pressure, mean arterial pressure, and peak expiratory flow rate before and after surgery to assess respiratory function and hemodynamic stability. These assessments aim to determine if the ESP block can provide better pain control and reduce opioid needs, enhancing patient recovery after nephrectomy.
