Morphine Consumption in Thoracotomy

Importance of effective postoperative pain management is well known. The undesired effects of pain can be prevented with multimodal analgesia for the patient. Thoracotomy operations are associated with high levels of pain. With the use of ultrasound, many regional anesthesia techniques were described to provide effective postoperative analgesia. The aim of this study was to compare the postoperative effect of paravertebral block (PVB) and erector spinal plane block (ESPB) in thoracotomies.
