Invasive hemodynamic monitoring in pregnancy.

Invasive hemodynamic monitoring is indicated in the critically ill pregnant or postpartum patient, whose hemodynamic state cannot be reliably determined by clinical observation and noninvasive methods. In addition, precise hemodynamic information must be indispensable to determine and monitor treatment. Complications of central hemodynamic monitoring using the Swan-Ganz catheter appear to be rare in experienced hands. To maintain and expand the necessary skills and experience, invasive hemodynamic monitoring should be centralized in obstetric intensive care units.
