During emergency care for a skull injury, what should the care provider do about blood or cerebrospinal fluid coming from the ears or nose?

In cases of skull injuries, the presence of blood or cerebrospinal fluid (CSF) leaking from the ears or nose is a significant concern, as it may indicate a serious condition such as a fracture of the skull base. When this occurs, it is important not to attempt to stop the flow of fluid. Attempting to plug the ears or nose can increase the risk of pressure building up, potentially leading to further injury or complications such as infection.

Allowing the fluid to flow freely is crucial because it can help minimize pressure in the skull and prevent additional damage. The cerebrospinal fluid contains essential components that cushion the brain, and obstructing its flow could exacerbate the situation.

Additionally, handling the situation appropriately includes seeking medical assistance as soon as possible, since a skull fracture and associated leaks are medical emergencies that require specialized intervention. Therefore, while actions such as encouraging the victim to lie down or seeking help are important parts of emergency care, they should not involve trying to stop the flow of fluid.
