The pain scores were recorded in the PACU, post-operatively and at the 1st, 12th, and 24th hours. Preoperative and postoperative arterial pressures and pulse rates were monitored and recorded at the beginning, 5th, 10th, 20th, 30th minutes, postoperatively and in PACU. <br> <b>Results: </b> Mean PI change rate measured at the beginning was significantly higher than those measured in all other times and when compared to the initial PI change rate, the rates of change were found to increase significantly in the 5th, 10th and 20th minutes (p<0.001). Mean arterial pressure and mean heart rate values measured at the beginning were significantly higher than those measured at all times (p<0.001). No intraoperative injection of fentanyl or infusion of remifentanyl were performed. The patients had no additional requirement of narcotics during the 24-hours follow-up period postoperatively, except for routine analgesics. <br> <b>Conclusions: </b> We think that peripheral blocks; especially in multimodal anesthetic applications, have intraoperative analgesic activity in addition to postoperative efficacy. They may also contribute to hemodynamic stabilization without narcotic requirement. The success of the blockade can reliably be evaluated by the PI measurement.}, number={1}, publisher={MEDİTAGEM Ltd. Şti.}
