I work in the Endo dept. in an upstate NY facility. We keep pts an hour form the last time they were medicated. We also have them sign their discharge papers prior to being medicated that states they will have someone to drive them home. We use Demerol and Versed in the smallest affective dose possible. The duration on these drugs are short acting, 2-4 hours for Demerol and depending on the dosage for Versed 1-5 hours. Some responsibility has to be placed on the pt for their own health and well being. They way hospital are run today, like a business, theres no way we could possibly keep people in over night. That is saved for the pt that needs it.:)
