Area of Science:

  • Anesthesiology
  • Critical Care Medicine
  • Cardiovascular Physiology

Background:

  • Adequate cardiac preload is vital for critically ill patients.
  • Optimizing cardiac output and tissue perfusion is a key therapeutic goal during thoracic surgery anesthesia.
  • Accurate preload estimation is challenging, with limited studies in thoracic anesthesia.

Purpose of the Study:

  • To review and analyze preload monitoring techniques in thoracic anesthesia.
  • To evaluate the indications and limitations of various monitoring devices.
  • To identify effective strategies for fluid and vasoactive therapy.

Main Methods:

  • Analysis of conventional pulmonary artery catheter (PAC) use.
  • Evaluation of transesophageal echocardiography (TEE) for preload assessment.

  • Review of transpulmonary indicator dilution (TPID) technique for volumetric monitoring.

    • Main Results:

    • Pulmonary artery catheter remains fundamental, especially for pulmonary hypertension.
    • Transesophageal echocardiography has limitations including operator dependency, low repeatability, and high costs.
    • Transpulmonary indicator dilution technique is a promising option for intravascular volume management.

    Conclusions:

    • Pulmonary artery catheter monitoring is recommended during lung transplantation.
    • Transesophageal echocardiography's clinical diffusion is limited by practical factors.
    • Transpulmonary indicator dilution technique provides effective monitoring for fluid balance and vasoactive drug administration in thoracic surgery.
