[Pulmonary artery catheter--its utility and limitations]

Area of Science:

• Cardiology
• Critical Care Medicine
• Anesthesiology

Context:

• Pulmonary artery catheters (PAC) have been widely used for perioperative hemodynamic monitoring in Japan since the 1970s.
• PAC provide quantitative circulatory data including pulmonary capillary wedge pressure, cardiac output, and mixed venous oxygen saturation.

Purpose:

• To evaluate the efficacy and limitations of perioperative pulmonary artery catheter monitoring.
• To discuss alternative, less invasive hemodynamic monitoring systems.

Summary:

• Despite extensive use, randomized controlled studies indicate that PAC do not decrease mortality rates.
• Aggressive therapeutic strategies employing PAC have been associated with increased patient morbidity and complications.
• Physician proficiency in PAC use, interpretation, and appropriate patient selection is essential.

Impact:

• Highlights the need for comprehensive training, education, and strict management protocols to optimize PAC benefits.
• Suggests considering less invasive monitoring alternatives like aortic waveform analysis and central venous oxygen saturation.
