The clinical effect of aspirin combined with low-molecular-weight heparin in the treatment of severe preeclampsia and the combination's effect on pregnancy outcomes

OBJECTIVETo explore the clinical effects of aspirin combined with low-molecular-weight heparin (LMWH) in the treatment of patients with severe preeclampsia and the combination's influence on pregnancy outcomes. METHODSFrom October 2018 to June 2020, 104 patients with severe preeclampsia who underwent treatment in our hospital were recruited as the study cohort and divided into two groups according to different treatment scheme each patient underwent. In the research group (RG), the 54 patients were administered aspirin combined with LMWH, and the other 50 patients in the control group (CG) were administered routine treatment. The total effective rates were compared between the two groups. The blood pressure, coagulation function, hemorheology, and renal function indexes were compared before and after the therapy. The Apgar scores of the newborns and the incidences of adverse pregnancy outcomes were measured at 1 and 5 minutes after the births. RESULTSAfter the therapy, the systolic blood pressure (SBP) and the diastolic blood pressure (DBP) in the RG were lower than they were in the CG. The PT and APTT in the RG were significantly higher than they were in the CG, and the FIB and D-D were significantly lower than they were in the CG. After the treatment, the hematocrit, the erythrocyte sedimentation rate, and the plasma viscosity in the RG were significantly lower than they were in the CG. The 24 h UP, BUN, UA, and Scr levels in the RG were significantly lower than they were in the CG. The Apgar scores of the newborns in the RG were significantly higher than they were in the CG at 1 min and 5 min after the births. After the therapy, the incidence of adverse pregnancy outcomes in the RG was significantly lower than it was in the CG, and the total effective rate in the RG was significantly higher than it was in the CG. CONCLUSIONAspirin combined with LMWH can effectively improve the clinical efficacy, the coagulation function, the renal function, and the blood pressure levels, and the combination can reduce adverse pregnancy outcomes in severe preeclampsia patients.
