Paravertebral Block or Serratus Posterior Superior Intercostal Plane Block in Pain Management After Video-Assisted Thoracoscopic Surgery: A Randomized Controlled Clinical Trial

Video-assisted thoracoscopic surgeries require a surgical incision of the lateral thoracic wall. In order to ease the postoperative pain of patients undergoing VATS, some regional anaesthesia techniques have been tried but there is no consensus on the best method. The gold standard peripheric nerve block is considered to be thoracal paravertebral block (TPVB). Recently, a new nerve block called serratus posterior superior intercostal plane block (SPSIPB) has been described. The anatomic and radiologic studies of SPSIPB suggest that the local anaesthetic distributes from C7 to T10 vertebrates, covering the surgical site of VATS. This study aims to compare the analgesic efficacy of TPVB and SPSIPB for VATS. The hypothesis is that participants receiving SPSIPB for VATS will have a less total opioid consumption 24 hours postoperatively. Also, the postoperative pain scores and opioid related side effects of the participants will be recorded. Participants will be divided in two groups. The group P will receive a TPVB preoperatively in the operating room. The group S will receive a SPSIPB preoperatively in the operating room. The participants will be followed 24 hours postoperatively and their total opioid consumption, numeric rating scores for pain, incidence of opioid related side effects will be recorded. Also the participants and the surgical teams perioperative pain related satisfaction will be evaluated.
