Objective To investigate the curative effect of low molecular weight heparin (LMWH) on preventing the formation of deep vein thrombosis (DVT) of high-risk pregnant women during pregnancy and puerperium. Methods A total of 1099 high-risk pregnancy patients were collected as LMWH group who received LMWH for preventing the formation of DVT in Zhujiang Hospital of Southern Medical University from January 2019 to July 2020; and 2107 high-risk pregnancy cases without LMWH were selected as control group from January 2016 to December 2018. SPSS 20.0 was employed for statistical analysis, and the number of thrombosis cases, the incidence of prepartal and puerperal hemorrhage, the cesarean section rate and other indicators were compared and analyzed between the two groups. Results After LMWH treatment, no new case of DVT occurred in LMWH group during pregnancy and puerperium, while there were 24 cases of new thrombosis in control group, the difference was statistically significant between the two groups (P=0.000). There were 2 cases of placental abruption before delivery occurred in the LMWH group, and only 1 case in control group. The 2 h postpartum hemorrhage was (182.25±120.62) ml in LMWH group, and (165.00±68.58) ml in control group. The cesarean section rate was 37.5% in LMWH group and 38.9% in control group. No significant differences existed in the incidence of placental abruption, postpartum hemorrhage and cesarean section between the two groups (P>0.05). Conclusion For pregnant women with high risk factors for thrombosis, LMWH can be used according to the score to prevent thrombosis, and it is safe and effective.
