Sensory Analysis and Cutaneous Mapping of Different Regional Anesthesia Techniques
Sponsor: Samsun University
Summary
This prospective observational study aims to evaluate and compare the sensory block distribution and regression patterns of two regional anesthesia techniques - External Oblique Plane Block (EOPB) and Serratus Intercostal Plane Block (SIPB) - in patients undergoing laparoscopic cholecystectomy. Thirty adult patients (ASA I-III, BMI ≤ 35 kg/m², ≥50 kg) scheduled for elective laparoscopic cholecystectomy procedures will be included, with 20 in each block group. Sensory block areas will be assessed using pinprick test, and dermatomal mapping will visualize the spread. The findings are expected to improve understanding of block behavior and guide multimodal analgesia strategies in laparoscopic cholecystectomy.

Interventions
External Oblique Plane Block (EOPB)
Ultrasound-guided External Oblique Plane Block (EOPB) performed bilaterally using 0.25% bupivacaine (25 mL per side, total 50 mL) for postoperative analgesia in laparoscopic cholecystectomy.
Serratus Intercostal Plane Block (SIPB)
Ultrasound-guided Serratus Intercostal Plane Block (SIPB) performed bilaterally using 0.25% bupivacaine (25 mL per side, total 50 mL) for postoperative analgesia in laparoscopic cholecystectomy.
