Summary
Brief summary (as posted)
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.

- Paravertebral Block (PVB)
- description
- Includes patients with paravertebral block as analgesic For the PVB, the patient was seated, and a 22G block needle was inserted into the paravertebral space at the T5 level under ultrasound guidance. The T5 level was selected to provide direct analgesia to the thoracic paravertebral space, which is known to block multiple thoracic nerves. After negative aspiration, 1 mL of saline was injected to confirm correct needle placement, and 20 mL of 0.375% bupivacaine was administered following hydrodissection.
- label
- Erector Spinae Plane Block (ESPB)
- description
- Includes patients with Erector Spinae Plane Block as analgesic. For ESPB, the patient was positioned in a seated posture, and under sterile conditions, a 22G, 80 mm Stimuplex® D block needle (B. Braun, Melsungen, Germany) was inserted between the T6 and T7 transverse processes and the erector spinae muscle via ultrasound guidance (Fujifilm Arietta 65, Tokyo, Japan). The T6-T7 level was chosen on the basis of its proximity to the thoracic surgical site, allowing for optimal coverage of the thoracic dermatomes. Following negative aspiration, 1 mL of saline was injected via hydrodissection to confirm correct needle placement, and 20 mL of 0.375% bupivacaine was administered.
