Impact of Transthoracic Echocardiography and Lung Ultrasound on Postoperative Cardiac Surgery Care

Medical And Health

Non-Communicable Diseases

The problem with current invasive postoperative monitoring of the postop heart is evident in the name.It is invasive and can lead to untoward effects to the patient and the medical staff. Lung ultrasound and transthoracic echocardiography is safe and can be repeated as often as needed without harming the patient or the staff.The same cannot be said about Pulmonary artery catheter use. Similarly, lung ultrasound can be repeated as often as needed with no harm. The same cannot be said about the chest x-ray. Non-invasive monitoring has been used in other criitical care areas but not in cardiac surgery patients. This is the first study of its kind on the postop heart.

1. Management of the postoperative open heart surgery patient demands accurate hemodynamic assessment. This is essential for predicting trends and making crucial life-saving decisions in a timely manner. The conventional approach involves invasive monitoring by pulmonary artery catheter (PAC), which has associated risks. With advances in ultrasound imaging most if not all of the parameters obtained by PAC can be obtained using echocardiography. Echocardiography has the added advantage of being safe to repeat as often as needed without causing any harm. 2. Chest x-ray is used frequently in the management of open heart surgery patients (at least one film daily). This carries a risk of radiation exposure for both the patient and the staff. Most of the information obtained by chest x-ray can also be obtained by lung ultrasound, though x-ray would still have a place in a few selected situations. 3. The value of echocardiography and lung ultrasound has been proven in critical care, but to our knowledge has not been studied for open heart surgery patients.
