Where are the data that show that 20 mg of terbutaline qiven SQ via infusion pump is FAR, FAR higher than giving it by the oral route. Show me the data! The dose used was perhaps higher than usual, but that "usual" dose was not obtained through well designed pharmacokinetic studies. A "Letter to the Editor" is hardly scientific evidence. LSR

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
