Fluid aspiration is a medical procedure used to remove excess fluid from a specific area of the body, often using a needle and syringe. This technique is commonly performed on areas like the abdomen, chest, or joints to relieve pressure, reduce discomfort, or obtain fluid samples for diagnostic purposes. During the procedure, a healthcare professional locates the fluid accumulation using imaging techniques such as ultrasound or CT scans. Once the fluid is accessed, it is carefully aspirated, allowing for analysis or alleviating symptoms associated with conditions like edema or pleural effusion.
