Summary:
Availability of an ultrasound device in the critical care setting significantly extends diagnostic options and
makes the management of critically ill patients more effective. A growing amount of papers confirm that
qualified intensivists can provide accurate, safe and extensive diagnosis of the haemodynamic system
with the aid of echocardiography. Intensivists involved in the management of the critically ill are fully aware
of all patient’s clinical and laboratory data and they should be able to interpret the echocardiographic
examination in a complex manner and with immediate application for further therapy. Performing echocardiography
in the intensive care unit requires on the other hand thorough knowledge of the devices and
principles of heart ultrasound. Task forces within societies of intensive care and cardiology launched
curriculla for training and data acquisition in echocardiography in the last three years. A complex
echocardiographic exam of the critically ill patient should include following items: preload, global and segmental
contractility, diastolic function, afterload, examination of the valvular apparatus, cardiac output,
right heart including the pulmonary artery and pulmonary artery pressure, aortic pathology, the pericardium
and examination of the pleural space. 10–11 planes should be taken during a routine transthoracic examination
and 12 planes during transesophageal echocardiography. Utilisation of an ultrasonic device
should not be limited to echocardiography. Examination of the pleural space, quantification of the pleural
fluid and an eventual exclusion of a ventral pneumothorax with the aid of a transthoracic probe should be
an integral part of a transthoracic echocardiographic examination. A multimodal ultrasonic device equipped
with a transesophageal probe should be available in all large intensive care units where its presence
would be justified by a high number of diagnosed and treated patients. This is also related to savings on
pulmonary artery catheters, X-ray material and platelet transfusions, besides the immediate and almost
complete diagnosis of the cardiovascular system.
