Local systemic filling pressure measurement can be used to determine other hemodynamic parameters such as venous return and the stressed volume. The aim of the present study was to evaluate the relationship between local systemic filling pressures and central venous pressure.
In this study, candidate patients of cardiac surgery in Imam Khomeini hospital of Ardabil, in the first half of the 1397, were chosen and studied by their satisfaction, then an intra-arterial catheter inserted to the upper limb, a tourniquet closed to the same arm. The arterial pressure measured during the surgery. Central vein pressure was also measured simultaneously. Finally, other variables obtained from transesophageal echocardiography and demographic data were recorded in each patient's checklist.
43 patients (71.7%) were man and 17 (28.3%) were women. The Mean CVP, MSFP, CO, and CI were 8.3±4.5 mmHg, 17.0±6.1, 3.27±1.1, and 1.89±0.7, respectively. Ten patients (16.7%) had mild heart failure, 42 patients (70%) had a moderate heart failure and 8 patients (13.3%) had severe heart failure. There were positive and significant relationship between CVP and MSFP (r=0.478: p=0.001). The EF status has no significant effects on CVP with
SBP, DBP, MAP, CO and CI. There was significant and reverse correlation between PSF value with CO, and CI in severe heart failure (p<0.05).
we concluded that the local MSFP is a good and valuable substitute for CVP
measurement, especially in severe heart failure.
