Assessment of Hemodynamic Parameters in Recipients of a Liver Transplant

The control of all hemodynamic parameters among patients after liver transplantation is critical for better graft survival and to reduce the risk of perioperative complications. The value of cardiac output (CO) and stroke volume (SV) below normal promote the development of cardiovascular diseases.

The study was conducted on a group of 43 patients after liver transplantation: 16 women and 27 men 0.5 to 29 years after the surgery at the Department of Transplantation Medicine, Nephrology and Internal Diseases, Institute of Transplantology, Medical University of Warsaw, Infant Jesus Clinical Hospital in Warsaw, Poland. The hemodynamic parameters were measured due to 4 electrocardiogram electrodes with the Cardiac Monitor ICON Osypka Medical.

Patients after liver transplantation (LTx) showed values of CO (average 5.27 L/min, standard deviation [SD] = 0.92) and stroke volume (average 67.08 mL, SD = 10.96) below normal. The average thoracic fluid content value among women is 21.81 (1/kΩ), SD = 3.28, and for men 24.04 (1/kΩ), SD = 4.75. Only 37% of patients had a body mass index with normal values, with 63% above expected values: 42% with overwise and 21% with a first stage of obesity.

The hemodynamic parameters should be controlled among patients after LTx. CO and SV below normal are predictors of a higher risk of cardiovascular diseases.
