Recent advances in intravenous therapy.

For trauma resuscitation, the American College of Surgeons Committee on Trauma recommends at least two large-bore intravenous lines for rapid fluid administration. Access to venous circulation may be difficult and challenging in emergency situations. The physician should be accomplished in numerous intravenous access techniques. Knowledge of flow characteristics for intravenous catheters will aid in the appropriate choice of equipment for successful emergency resuscitation.
