Status Recruiting

Clinical Trial Summary

The aim of this study is to investigate the analgesic effect of local versus systemic dexamedetomedine as adjuvant to bupivacaine in erector spinae block in kidney exploration surgeries.

Clinical Trial Description

Open Kidney surgeries remain one of the approaches used for those patients are requiring partial or radical nephrectomy and is associated with a high incidence of intense immediate postoperative pain and chronic pain for months following surgery. Effective treatment of postoperative pain allows early mobilization of the patient, shortens the recovery and discharge time, prevents the development of chronic pain, and increases satisfaction and long-term quality of life. Current modalities used to manage pain for patients undergoing kidney exploration include oral and parenteral opioid administration, local anesthetic infiltration, and certain neuraxial and regional anesthesia procedures including thoracic epidurals and paravertebral blocks. The erector spinae plane (ESP) block is a newer regional anesthetic technique that can be used to provide analgesia for a variety of surgical procedures or to manage acute or chronic pain. The technique is relatively easy to perform on patients, and it is performable with minimal or no sedation in the pre-operative holding area. Ultrasound is a non-invasive visualization technology that helps capture the anatomical structure of target tissues; it can help guide the direction and depth of anesthesia puncture needles, thus reducing the risk of complications. The local anesthetic drugs have a limited duration of action, so we need to add adjuvants such as opioids, alpha two agonists, neostigmine, or magnesium. Dexmedetomidine is a potent α2 agonist and is a powerful adjuvant to regional anesthesia and analgesia. It can prolong the duration of the nerve block anesthesia resulting in increased effectiveness of the block in terms of duration, less use of opioids, and shorter hospital stay in the absence of clinically significant side effects (hypotension, nausea, vomiting, and pruritus. Adding adjuvants to local anesthetics is frequently used to prolong the duration of single-injection regional nerve block. There have been multiple studies claiming increased effectiveness of use of dexmedetomidine and this has been consolidated in a meta-analysis examining the effectiveness of dexamedetomedine as a peripheral nerve block adjuvant. ;
