Comparing Preoperative and Intraoperative Erector Spinae Plane Block to Reduce Opioid and Anesthetic Use in Lumbar Disc Herniation Surgery

What this Trial Is About

Lumbar disc herniation LDH is a common spine disorder often treated surgically using methods like discectomy, microdiscectomy, or stabilization. This research evaluates how different timing of erector spinae plane block ESPB, a regional anesthesia technique, affects opioid use, anesthetic consumption, and hemodynamic stability during LDH surgeries. The study aims to find ways to reduce opioid side effects, improve pain control, and lower healthcare costs related to anesthesia and analgesia. Participants undergoing LDH surgery will be randomly assigned to receive ESPB either before surgery preoperative or during surgery intraoperative. Both methods involve injecting local anesthetic guided by ultrasound to numb nerves around the spine. Patients will receive standard general anesthesia with sevoflurane and opioids, and postoperative pain management includes intravenous morphine via patient-controlled analgesia and other pain medications. The study compares the effects of preoperative versus intraoperative ESPB on drug use and patient stability. During the study, researchers will monitor vital signs such as blood pressure, heart rate, oxygen saturation, and anesthetic depth at multiple time points before, during, and after surgery. Pain levels will be measured using a 100-point visual analog scale at rest and during movement up to 48 hours post-surgery. Opioid consumption, additional pain medication needs, and side effects like nausea, dizziness, and respiratory issues will also be recorded. The trial will enroll 60 adults aged 18 to 75 undergoing LDH surgery and follows them through the immediate postoperative period to assess outcomes.
