This study aims to evaluate changes in perfusion index (PI) in pediatric patients undergoing elective surgery under low-flow anesthesia. PI will be monitored at multiple intraoperative and postoperative time points to assess its relationship with hemodynamic stability and depth of anesthesia. The study will also investigate whether low-flow anesthesia affects the incidence of emergence agitation (EA). Patients will be assigned to either low-flow or normal-flow anesthesia groups based on routine clinical practice. No intervention will be applied beyond standard care. The findings are expected to provide insight into the predictive value of PI in postoperative recovery and support safer anesthesia practices in pediatric populations.
