Which fluid is commonly added to a procedure tray for irrigation?

Normal saline is commonly added to a procedure tray for irrigation due to its isotonic properties and compatibility with body fluids. It is a sterile solution of sodium chloride in water that closely resembles the salt concentration found in the human body, making it ideal for various medical applications, including irrigation during surgical or interventional procedures.

Irrigation with normal saline helps to maintain the area being treated by flushing out debris, keeping tissues moist, and reducing the risk of infection. Its widespread availability and safety profile contribute to its preference in clinical settings. The use of normal saline is also supported by guidelines and protocols in interventional radiology, where maintaining a clean and clear surgical field is essential for optimal outcomes.
