The thought of putting your child to sleep for surgery or an MRI may make you think twice about the procedure. Rest assured, anesthesia and sedation are safe, even in young children. As with any drug, anesthetics and sedatives can have side effects, including severe allergic reactions. But this is very rare, and if a complication does arise, there are many interventions to counteract it. Once an operation or MRI is deemed necessary, don’t let the risks of anesthesia dissuade you from going forward.
