Comparing the QoR of PECS Block and GA in Breast-conserving Surgery With Sentinel Lymph Node Biopsy

The aim of this randomized controlled trial (RCT) is to assess the Quality of Recovery (QoR) in Breast-conserving Surgery (BCS) with Sentinel Lymph Node Biopsy (SLNB) using Pectoral Nerves (PECS) Block and General Anesthesia (GA). The primary objectives are as follows: First, to determine if the PECS group exhibits better QoR; Second, to investigate if the PECS group experiences less postoperative pain and complications; Third, to examine if the PECS group demonstrates more stable hemodynamics.
