If a child’s anxiety level cannot be soothed with nitrous oxide or the treatment needs are too extensive, oral conscious sedation may be helpful. Conscious sedation will cause the child to be drowsy and more cooperative. Several different conscious sedation medications are available based on the needs of the treatment. Side effects may include drowsiness, nausea and vomiting, which can be minimized by following specific eating and drinking directions before and after sedation. The child will be drowsy after the procedure and must be monitored by an adult for the remainder of the day.
