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.

目的 探讨应用低分子肝素(LMWH)预防高危妊娠孕产妇孕期、产褥期深静脉血栓形成的效果。方法 收集南方医科大学珠江医院2019年1月—2020年7月应用LMWH预防深静脉血栓形成的1099例高危妊娠病例作为LMWH组，选取2016年1月—2018年12月未使用LMWH的2107例高危妊娠病例作为对照组，比较分析两组血栓形成例数、产前及产后出血发生率、剖宫产率等指标。结果 LMWH组无新发妊娠期及产褥期深静脉血栓，而对照组有新发血栓24例，两组比较差异有统计学意义(P=0.000)。LMWH组产前发生胎盘早剥2例，对照组产前发生胎盘早剥1例；LMWH组产后2 h出血量为(182.25±120.62) ml，对照组为(165.00±68.58) ml；LMWH组剖宫产率为37.5%，对照组为38.9%。两组胎盘早剥发生率、产后2 h出血量、剖宫产率等比较差异均无统计学意义(P>0.05)。结论 对有血栓高危因素的孕产妇，根据评分使用LMWH可预防血栓形成，且安全有效。

目的 探讨应用低分子肝素(LMWH)预防高危妊娠孕产妇孕期、产褥期深静脉血栓形成的效果。方法 收集南方医科大学珠江医院2019年1月—2020年7月应用LMWH预防深静脉血栓形成的1099例高危妊娠病例作为LMWH组，选取2016年1月—2018年12月未使用LMWH的2107例高危妊娠病例作为对照组，比较分析两组血栓形成例数、产前及产后出血发生率、剖宫产率等指标。结果 LMWH组无新发妊娠期及产褥期深静脉血栓，而对照组有新发血栓24例，两组比较差异有统计学意义(P=0.000)。LMWH组产前发生胎盘早剥2例，对照组产前发生胎盘早剥1例；LMWH组产后2 h出血量为(182.25±120.62) ml，对照组为(165.00±68.58) ml；LMWH组剖宫产率为37.5%，对照组为38.9%。两组胎盘早剥发生率、产后2 h出血量、剖宫产率等比较差异均无统计学意义(P>0.05)。结论 对有血栓高危因素的孕产妇，根据评分使用LMWH可预防血栓形成，且安全有效。

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.

孕产妇血液处于高凝状态，同时因受增大的子宫压迫，下肢静脉血液回流速度变慢，容易发生深静脉血栓(deep venous thromboembolic，DVT)，尤其是下肢DVT[1]甚至可导致肺栓塞，严重影响孕产妇和胎儿的生命安全。而高危妊娠孕产妇，如有血栓病史或家族史，合并易栓症、系统性红斑狼疮(SLE)、干燥综合征等凝血、免疫系统疾病，双胎妊娠，合并妊娠高血压、妊娠糖尿病等孕期并发症，肥胖、多产、剖宫产、产后出血等，则更容易发生DVT[2]。因此，对伴有血栓高发风险的孕产妇，预防妊娠期及产褥期DVT可降低其死亡风险并避免因DVT而导致的胎儿丢失，具有重要的临床意义。但目前国内对于如何预防孕产妇血栓形成的报道较少。自2019年1月以来，南方医科大学珠江医院对所有孕产妇进行血栓高危因素评分，并针对有高风险因素的孕产妇应用低分子肝素(LMWH)预防血栓形成，取得了满意效果，现报道如下。
1 资料与方法
收起
1.1 临床资料
收集南方医科大学珠江医院2019年1月—2020年7月应用LMWH预防DVT形成的1099例高危妊娠病例作为LMWH组。因2019年之后评估有血栓高危因素的孕产妇均常规使用了LMWH预防血栓形成，故选取2016年1月—2018年12月未使用LMWH的2107例高危妊娠病例作为对照组。DVT的诊断依据为：患者出现患肢疼痛、肿胀或头痛等症状，查体患肢(如腿围)较对侧增大、腓肠肌压痛等，凝血功能检查D-二聚体可升高。确诊依据为血管超声检查提示DVT形成。本研究已通过南方医科大学珠江医院伦理委员会批准。
1.2 观察指标
包括孕产妇的年龄，孕产次，受孕方式，孕前的体重指数，是否有血栓病史或家族史，是否有吸烟、饮酒、吸毒等不良嗜好，分娩方式，是否有妊娠期合并症及并发症(如妊娠高血压、系统性红斑狼疮、易栓症、妊娠糖尿病等)，是否有分娩并发症如产后出血等。应用LMWH前及应用期间每月定期复查血常规、凝血功能、肝肾功能等指标。
1.3 血栓高危因素评分标准及LMWH使用时间
参考相关文献[3]及2015年英国皇家妇产科医师学会(RCOG)指南[4]，对所有孕产妇进行血栓高危因素评分(表1)。主要依据患者的年龄、产次、体重指数、受孕方式(是否为人工受孕)、分娩方式(是否为剖宫产)、是否为多胎妊娠、有无孕前血栓病史及血栓家族史、有无孕期并发症及合并症(如妊娠糖尿病、妊娠高血压疾病、易栓症、抗磷脂综合征等)、有无胎膜早破(>24 h)、是否发生产后出血等进行综合评分。评分分为产前≥4分，产前=3分，产后≥3分，产后=2分。对产前评分≥4分者，早孕期开始应用LMWH预防血栓形成；产前评分=3分者，孕28周开始预防应用LMWH。产后评分≥3分者，产后至少使用LMWH 7 d；产后评分=2分者，住院期间使用LMWH。孕期有血栓形成或既往有DVT病史者，产后LMWH使用42 d。
1.4 统计学处理
采用SPSS 20.0软件进行统计分析。计量资料以$\bar{x}±s$表示，两组间比较采用t检验；计数资料以例(%)表示，两组间比较采用χ2检验或Fisher精确检验。P<0.05为差异有统计学意义。

2.1 一般情况比较
两组孕产妇年龄，使用LMWH前血小板计数、纤维蛋白原及D-二聚体等凝血功能指标差异均无统计学意义(P>0.05，表2)。
2.2 并发症比较
LMWH组产前血栓高危因素评分≥4分者3例、=3分者37例，产后评分≥3分者476例、=2分者583例；应用LMWH后孕期及产褥期无新发血栓形成。对照组产前血栓高危因素评分≥4分者4例、=3分者18例，产后评分≥3分者816例、=2分者1269例；孕期及产褥期共有24例发生DVT，其中下肢DVT 22例，上肢DVT 1例，颈静脉DVT 1例。两组DVT发生率比较差异有统计学意义(P=0.000，表3)。LMWH组产前评分≥3分者发生胎盘早剥2例(2/40)，对照组产前评分≥3分者发生胎盘早剥1例(1/22)，两组产前胎盘早剥发生率比较差异无统计学意义(P=0.931)。两组产后2 h出血量、剖宫产率、新生儿出生天数、新生儿窒息率等比较差异均无统计学意义(P>0.05，表3)。两组使用LMWH期间均定期监测血常规、凝血功能、肝肾功能等指标，均未发生严重血小板减少、凝血功能异常、肝肾功能损害。孕期均未发生颅内出血、严重的皮下出血等出血并发症。

静脉血栓形成的高危因素主要为血流淤滞、血管损伤及高凝状态[5]。目前的观点认为，高危妊娠孕产妇较正常妊娠孕产妇更容易发生DVT[6]，需根据高危评分常规预防DVT的形成。而高龄(>35周岁)、孕前肥胖、多胎妊娠是孕妇DVT形成的高危因素[7]。妊娠期DVT的发生率随孕妇体重的增加而增高，>35岁孕产妇发生静脉血栓栓塞症的相对危险度增加约2倍[8]。有研究发现，对于高危妊娠孕产妇，产程延长、合并妊娠高血压疾病、产后出血等均可增加其血栓形成的风险[9]。合并易栓症、SLE等凝血系统疾病、自身免疫系统疾病等亦是导致妊娠期DVT形成的重要原因[10]。还有研究发现，妊娠糖尿病患者存在血小板活化现象，长期高血糖可损伤血管内皮，使血栓形成发生率增高[11]，因此，本研究将妊娠糖尿病也纳入血栓形成的高危因素。本课题组既往研究发现，大部分发生DVT的孕产妇均存在高危因素[12]，因此，很有必要对孕产妇进行血栓高危因素评分，并根据评分结果有针对性地预防血栓形成，以尽量避免孕产妇发生DVT。
目前对于血栓的预防及治疗仍主要采用生活方式干预及注射LMWH[13]。LMWH对Ⅹa和Ⅻa因子的抑制作用较强，但对血小板功能的影响较小，因此可减少出血等不良反应。此外，LMWH与血浆蛋白结合能力低，生物利用度更高[14]。同时，LMWH不通过胎盘，不引起胎儿畸形，安全可靠[15]。但是，对具有血栓形成高危因素的孕产妇，LMWH的使用时间目前尚无定论。本研究对产后高危因素评分≥3分者(除外血栓病史及孕期血栓形成者)统一采用产后注射LMWH 7 d的方案，并嘱产妇尽量避免长期卧床，所有产妇均未发生血栓。此方法提高了患者的依从性，同时减少了长时间使用LMWH带来的不利影响。本研究在LMWH治疗期间定期监测孕产妇的相关血液学指标，因此未发生严重的血小板减少、肝肾功能损害、颅内出血等并发症，与对照组比较，LMWH组孕妇产后2 h出血量未见增加，胎盘早剥发生率、剖宫产率、新生儿窒息率及早产发生率均未增高。
综上所述，本研究结果表明，LMWH能有效预防孕产妇发生DVT，且安全性高。因此，临床上应对所有孕产妇进行血栓高危因素评分，对有血栓形成高风险的孕产妇根据评分结果采取相应的预防措施，可有效避免孕产妇发生DVT，降低孕产妇并发症及死亡发生率，并减少因此带来的胎儿丢失。孕期及产褥期应用LMWH不增加产前、产后出血量，未增高剖宫产率、早产及新生儿窒息率等，提示其安全、有效，无明显不良反应。但本研究为回顾性研究，且观察指标有限，后续将进一步进行前瞻性对照研究，更深入地探讨LMWH对孕产妇DVT的预防作用，同时可结合物理治疗如下肢气压治疗等，以达到更好的预防血栓形成的效果。
