Abstract
This work had been carried out at the intensive care unit (ICU), of The Prince charles Hospital, Brisbane, Queensland, Australia After obtaining approval from The Prince charles Hospital ( TPCH ) ethics committee, Sight Specific Approval and Public Health Act. This observational study was conducted between January 2013 to January 2014. The study included 40 patients admitted to ICU of both sex, aged 20 - 75 years who showed criteria for sepsis according to American Collage of Chest Physicians / Society of Critical Care Consensus Criteria and fulfills the inclusion criteria. The aim of the study to evaluate and correlate the indices of the heart functions in septic patients obtained by two different modalities, First, pulmonary artery catheterization ( PAC) to measures right atrial pressure ( RAP), cardiac output ( COP), and cardiac index ( CI ). Second, Noninvasive bedside transthoracic echocardiography ( TTE ) to measure inferior vena cava diameter ( IVCD ) which is a guidance of the volume status, cardiac output ( COP ), and cardiac index ( CI ) .
After examining the patient and obtaining all the pertinent clinical information including comprehensive PAC data (full hemodynamic profile, including right heart pressures, pulmonary wedge pressure, cardiac output [COP] and venous blood gases). Transthoracic echocardiography (TTE) has been performed within 4 hours of PAC.
After obtaining hemodynamic data of the study from the enrolled 40 patients by the two different methods an analytic study was done between the following:
1. Echocardiographic expiratory inferior vena cava diameter [IVCD] vesus mean central venous pressure derived from continuous PAC derived hemodynamic data [CVPp].
2. Calculated central venous pressure [CVPc] versus central venous pressure derived from continuous PAC derived hemodynamic data [CVPp],
3. Echocardiographic cardiac output indices [COPe] versus cardiac output derived from continuous PAC derived hemodynamic data [COPp].
4. Echocardiographic cardiac index [CIe] indices versus cardiac index derived from continuous PAC derived hemodynamic data [CIp].
Our study demonstrated that there were a significant positive correlation and a complete agreement between both transthoracic echocardiography and pulmonary artery catheter derived hemodynamic data in determining central venous pressure, cardiac index and cardiac output.
Our study concluded that Echocardiography is a noninvasive mean to assess hemodynamic variables can provide an accurate assessment of cardiac function and preload status. Also, Bedside echocardiography is teachable and should become a part of future critical care curricula.
