Patient care

The antrum is irrigated with the prescribed solution (often warm normal saline solution) according to protocol. The character and volume of the returned solution and the patient's response to treatment are carefully monitored and documented. Ice packs are applied as prescribed for edema and pain; these are replaced by warm compresses as healing progresses. Assessments are made for chills, fever, nausea, vomiting, facial or periorbital edema, visual disturbances, and personality changes, which may indicate the development of complications.
