Experience with the pulmonary artery catheter in obstetrics and gynecology

Although traditionally the exclusive domain of other medical specialties, pulmonary artery catheterization may be of tremendous benefit to a variety of obstetric and gynecologic patients. Our experience with such invasive hemodynamic monitoring in 72 patients in an obstetrics and gynecology service is presented. In 86% of cases, catheter placement and primary management were carried out by residents in obstetrics and gynecology. Although many of the indications for pulmonary artery catheterization encountered are common to other areas of medicine, certain conditions such as severe preeclampsia or rheumatic heart disease in pregnancy involve pathophysiologic conditions unique to our specialty. On the basis of our experience, recommended indications for pulmonary artery catheterization in obstetric and gynecologic patients are presented. Insertion techniques, complications, and clinical outcome are discussed.
