The goal of this clinical trial is to compare the analgesic efficacy of thoracal paravertebral block (TPVB) and serratus posterior superior intercostal plane block (SPSIPB) in patients undergoing video-assisted thoracoscopic surgery (VATS). The main questions it aims to answer are:
How will the total perioperative opioid consumption of the patients receiving two different blocks change? How will TPVB and SPSIPB effect the patients' numeric rating scores for pain in the postoperative 24-hour period? How will TPVB and SPSIPB effect the incidence of opioid related side effects?
Participants will be divided in two groups:
TPVB group will receive a TPVB before the surgery. SPSIPB group will receive a SPSIPB nerve block before the surgery. Researchers will compare the results between the groups to see the postoperative effects concerning opioid consumption as well as the pain scores, respiratory parameters and opioid associated side effects.
The hypothesis of this study is that participants receiving SPSIPB for VATS will have a less total opioid consumption 24 hours postoperatively.
