When dealing with a chemical eye injury, how long should irrigation typically last?

In the case of a chemical eye injury, it is critical to begin irrigation as soon as possible to minimize tissue damage and ensure the best possible outcome for the affected eye. The recommended duration for irrigation is typically at least 20 minutes. This extended period allows for the thorough washing away of the chemical substance, which is essential because many chemicals can cause serious and lasting harm if not adequately removed.

During the irrigation process, continuous or regular flushing with a copious amount of appropriate solution, such as saline or clean water, is important to dilute and neutralize the chemical agents present. The longer duration helps to effectively reach all parts of the eye, particularly in cases where the chemical may have penetrated deeper into the eye structure.

Although shorter times are sometimes mentioned in guidelines, they do not provide sufficient time to ensure that all residual chemicals are eliminated. Therefore, the emphasis on a minimum of 20 minutes of irrigation is vital for effective treatment of chemical eye injuries.
