At 60 min, compared to baseline, there was an increase in cardiac output (7.7 \u00b1 0.5 to 8.5 \u00b1 0.6 L\/min, p &lt; 0.02) and a tendency for right atrial pressure to decrease (9.3 \u00b1 0.8 to 7.50 \u00b1 0.8 mm Hg, NS), with no change in pulmonary capillary wedge pressure (10.9 \u00b1 0.9 to 10.7 \u00b1 0.9 mm Hg). Between 3 and 12 hr later, there was a drop in right atrial pressure, pulmonary capillary wedge pressure and cardiac output to 5.6 \u00b1 0.6 (p &lt; 0.02), 7.2 \u00b1 0.8 mm Hg (p &lt; 0.002) and 7.2 \u00b1 0.6 L\/min (NS) respectively, indicative of the development of relative hypovolemia and suggesting that therapeutic plasma expansion is appropriate at this time. Two\u2013dimensional echocardiography before paracentesis (n = 8) showed a reduction in the right to left atrium area ratio as compared with values in patients with minimal ascites (0.54 \u00b1 0.04 vs. 0.82 \u00b1 0.02, p &lt; 0.0001). This technique may help in identifying patients with right atrial compression caused by tensea ascites.(HEPATOLOGY 1990; 11:662\u2013667.)<\/jats:p>\n
