Optimizing Post-Thoracotomy Pain Management: Comparing Erector Spinae vs. Paravertebral Block in Thoracotomy Patients

This prospective, observational study included ASA class II-III patients aged 18-70 years who underwent elective unilateral lobectomy via a thoracotomy. The study was conducted at Başakşehir Çam and Sakura City Hospital, following approval from the hospital's ethics committee on May 20, 2022 (protocol number: KAEK.2022.05.155). Patients were randomized into two groups based on the type of preoperative block administered: ESPB (n = 30) and PVB (n = 30). Intravenous patient-controlled analgesia was provided for 24 hours postoperatively. Resting NRS and Prince Henry Hospital Pain Scale (PHHPS) scores were evaluated at 0, 2, 6, 12, and 24 hours after surgery. Pain levels were further assessed via telephone interviews using the NRS at 2 weeks and 2 months postoperatively.
