Study of Perfusion Index Changes and Recovery After Low-Flow Anesthesia in Children Aged 2 to 12 Undergoing Elective Surgery

What this Trial Is About

This research aims to study changes in the perfusion index PI in children aged 2 to 12 years undergoing elective surgery with anesthesia. It evaluates how PI relates to stability of blood flow and depth of anesthesia during surgery, and whether using low-flow anesthesia affects the chance of experiencing agitation after waking up. The study involves pediatric patients without major health issues, focusing on anesthesia safety and recovery. Participants will be randomly assigned to one of two groups receiving general anesthesia with different fresh gas flow rates one group at 1 liter per minute low-flow anesthesia and the other at 2 liters per minute normal-flow anesthesia. Both groups will have their perfusion index and other heart and blood flow measurements monitored at specific times before, during, and after surgery. No extra treatments beyond standard care are applied. During the study, researchers will track perfusion index changes from the start of anesthesia until 30 minutes after the breathing tube is removed. They will also assess the occurrence of emergence agitation after surgery. Parents or guardians will provide consent, and the study will be conducted under close observation to ensure patient safety. The findings aim to help improve anesthesia practices and recovery in children.
