Özet
Objective: Postoperative pain following craniotomy is a significant concern, primarily resulting from surgical incisions and fixation devices. Effective pain management involves various strategies, including systemic analgesics, patient-controlled analgesia, and regional anesthesia techniques. Among regional anesthesia methods, the scalp block provides effective pain control by blocking the nerves innervating the scalp with local anesthetics. This study aimed to evaluate the effectiveness of the scalp block in reducing postoperative pain in craniotomy patients, assessed using the numerical rating scale (NRS). Methods: Patients were divided into two groups: Group S, receiving the SCALP block, and group C, serving as the control group. Pain scores were recorded at 0, 2, 4, 6, 8, 12, and 24 hours postoperatively. Secondary outcomes included total amount of tramadol administered for rescue analgesia, time to first analgesia, postoperative nausea and vomiting (PONV) incidence, and patient satisfaction. Results: Group S demonstrated significantly lower NRS scores than Group C at all measured time points (p<0.001). The median time to first rescue analgesia was 12 (8-12) hours in group S, while it was 0 (0-1) hours in group C (p<0.001). Tramadol consumption was significantly reduced in group S [75 (60-123) mg] compared to Group C [280 (220-280) mg; p<0.001]. Conclusion: The scalp block effectively manages postoperative pain, reduces analgesic requirements, and improves patient comfort. It also minimizes complications such as PONV, making it a valuable option for postoperative care following craniotomy.
