Objective: Evaluation of the effectiveness of ultrasound (US)-guided erector spinae plane block (ESPB) and thoracic paravertebral block (TPVB) compared to no intervention control group for postoperative pain management in video assisted thoracic surgery (VATS) patients. Method: Three groups - Group ESPB, Group TPVB and the control group (n=30 per group) were included in this prospective, randomized, controlled study. The US-guided blocks were performed preoperatively in the ESPB and TPVB groups. Intravenous patient-controlled postoperative analgesia via fentanyl was administered in all of the patients. The patients were evaluated using visual analogue scale (VAS) scores, opioid consumption, and adverse events. Results: At all time intervals fentanyl consumption and VAS scores were significantly lower both in ESPB and TPVB groups compared to the control group (p<0.001). Block procedure time was significantly lower and success of one time puncture was higher in Group ESPB as compared with that in Group TPVB (p<0.001). Conclusion: ESPB and TPVB provide more effective analgesia compared to control group in patients who underwent video-assisted thoracic surgery. ESPB had a shorter procedural time and higher success of single-shot technique compared to TPVB.
