In the United States there are no federal guidelines for the scope of practice for any level of EMS provider. In the field, paramedics follow a set of pre-approved procedures and interventions for particular scenarios. For example, all fifty states allow for the administration of some form of anti-convulsive. In the state of Massachusetts a paramedic may administer the anti-convulsant, midazolam, up to a maximum of 6mg . While in Maine paramedics are allowed to administer midazolam in upwards of 10mg boluses. These pre-approved procedures are known as standing orders. Standing orders cannot surpass a provider's scope of practice. Scopes of practice represent the degree to which providers are trained.
