[Hemodynamic surveillance in pregnancy induced hypertension during volume expansion therapy].
Hemodynamic parameters were studied in 80 cases of pregnancy induced hypertension (PIH) using noninvasive cardiovascular detector (TP-CBS). Women were categorized into 3 kinds of hemodynamic patterns: (1) normal cardiac output, 45 cases, cardiac index (CI) = 2.5-4 L.min-1/m2; (2) high cardiac output, 10 cases, CI greater than 4 L.min-1/m2; (3) low cardiac output, CI less than 4 L.min-1/m2, 25 cases (31.5%). Ten cases in each category were selected for test after volume expansion therapy. MAP decreased in varying degrees. CI showed marked increase in the low cardiac output group, but decreased to normal in the high output group. The monitoring criteria for protecting against pulmonary edema during volume expansion therapy were discussed.
