Abstract：【Objective】To retrospectively analyze the effects of different fluid balance on the prognosis and hospital stay of patients with severe preeclampsia. 【Methods】A total of 683 patients with severe preeclampsia who underwent cesarean section in our hospital was selected. The water inflow and outflow for 24 hours were recorded in the first 3 days after operation. They were divided into three groups according to different fluid balance after operation. Group A was positive fluid balance (n=134, fluid inflow and outflow within 3 days after operation >200 mL), and group B was fluid balance (n=189, fluid inflow and outflow within 3 days after operation -200~200 mL), Group C was the negative fluid balance group (n=360, the amount of fluid in and out within 3 days after operation was ≤-1000 mL). The heart rate, blood oxygen saturation, maximum systolic blood pressure, maximum diastolic blood pressure, brain natriuretic peptide (BNP), urinary specific gravity and the length of hospital stay in each group were compared 3 days after operation, and the negative rate of urinary protein, blood pressure and BNP return to normal 42 days after delivery were compared. 【Results】The blood oxygen saturation of the group A and the group B was lower than that of the group C (P<0.05), but there was no significant difference between the group A and the group B (P>0.05); The heart rate, maximum systolic blood pressure, maximum diastolic blood pressure and hospital stay in the group A and the group B were significantly higher than those in the group C (P<0.05), but there was no significant difference between the group A and the group B (P>0.05); There was no significant difference in BNP level and urinary specific gravity among the three groups (all P>0.05). At 42 days postpartum, the negative rate of urinary protein in group A was lower than that in the group C (P<0.05), and the return to normal rate of blood pressure in the group A was lower than that in the group B and the group C (P<0.05), but there was no significant difference between the group B and the group C (P>0.05); BNP returned to normal in the three groups, and there was no significant difference (P>0.05). 【Conclusion】The negative balance of fluid inflow and outflow after severe preeclampsia can improve the patient's blood pressure, increase the blood oxygen saturation, reduce the length of hospital stay, and effectively improve the patient's prognosis.
