Objectives: Postthoracotomy pain requires multimodal perioperative management, including systemic and regional techniques. This prospective, randomized study aimed to evaluate postthoracotomy pain scores using the visual analog scale (VAS) as well as consumption of analgesic in 24 h and complications.
Methods: The patients were randomly assigned into four groups (25 patients each group) according to the analgesia technique used: Intercostal nerve block (ICB), thoracic epidural block (TEB), ultrasonography-guided erector spinae plane block (ESPB), and ultrasonography-guided thoracic paravertebral block (TPVB) groups. Multimodal analgesia was achieved with tramadol, paracetamol, and intravenous pethidine via patient-controlled analgesia (PCA) for all patients. The VAS scores at 30, 60, 90, 120 min, 6, 12, and 24 h postoperatively, consumption of analgesic at the first 24 h, rescue analgesic requirement, and side effects were recorded.
Results: The VAS scores were the highest in the ICB group and the lowest in the TPVB group at all time periods after thoracotomy (p<0.05). Likewise, total pethidine dose, number of PCA trials, and PCA data were determined to be at least in the TPVB group. However, only the number of PCA trials was found to be statistically significant (p=0.03). In terms of side effects, no difference was observed between the groups. Nausea and vomiting occurred in two patients in the ICB and ESPB groups, whereas hypotension occurred in two patients in the TEB group.
Conclusion: In conclusion, ultrasound-guided single-injection TPVB is more reliable and preferable in thoracotomy, as it is associated with low pain scores and has no side effects.
