Comparıson of Analgesıc Effıcacy of Dıfferent Volumes of Spsıp Block After Modıfıed Radıcal Mastectomy Surgery
Sponsor: Cumhuriyet University
Summary
The aim of researchers is to compare the effects of three different local anesthetic concentrations and volumes on opioid consumption, postoperative analgesic efficacy, and pain scores during ultrasound-guided SPSIP blocks in patients undergoing modified radical mastectomy. Additionally, we aim to map and identify the dermatomal areas where different concentrations and volumes of SPSIP blocks provide analgesia.
