低分子量肝素联合新鲜冰冻血浆在危重新生儿凝血功能异常中的应用

  目的  探讨低分子量肝素联合新鲜冰冻血浆在危重新生儿凝血功能异常中应用的临床效果。  方法  选取蚌埠医学院第二附属医院新生儿病房2019年2月—2020年8月收治的危重凝血功能异常患儿72例，采用随机数字表法分为观察组(35例)，对照组(37例)。所有患儿入院后6 h内检测凝血酶原时间(PT)、活化部分凝血酶时间(APTT)、纤维蛋白原(FIB)、凝血酶时间(TT)、D-二聚体(D-D)及血小板(PLT)水平。对照组进行针对原发病的常规治疗，观察组在常规治疗的基础上加用低分子量肝素与新鲜冰冻血浆，治疗72 h后复测上述指标。比较2组患儿的临床疗效、凝血功能指标及并发症发生率。  结果  治疗后，观察组总有效率高于对照组，差异有统计学意义(P < 0.05);2组治疗前PT、APTT、FIB、TT、D-D和PLT水平差异无统计学意义(均P>0.05);治疗后观察组PT、APTT、TT及D-D水平均低于对照组，且FIB水平高于对照组，差异有统计学意义(均P < 0.05);治疗后2组PLT水平比较差异无统计学意义(P>0.05)。治疗后2组PT、APTT、TT和D-D水平均低于治疗前，且FIB水平高于治疗前(均P < 0.05);治疗后2组PLT水平高于治疗前(均P < 0.05);治疗后2组颅内出血、消化道出血及肺出血等并发症发生率比较差异无统计学意义(均P>0.05)。  结论  低分子量肝素联合新鲜冰冻血浆在危重新生儿凝血功能异常中的早期干预可以改善临床症状，使凝血功能尽早恢复，具有较好的临床效果。 

Application of low molecular weight heparin combined with fresh frozen plasma in the treatment of coagulation abnormalities in critically ill neonates

Objective To investigate the clinical effects of low molecular weight heparin combined with fresh frozen plasma in the treatment of abnormal coagulation functions in critically ill neonates.Methods Seventy-two critically ill children with coagulopathy admitted to the neonatal ward of The Second Affiliated Hospital of Bengbu Medical College from February 2019 to August 2020 were selected and divided into an observation group(n=35)and a control group(n=37).Prothrombin time(PT),activated partial thromboplastin time(APTT),fibrinogen(FIB),thrombin time(TT),D-Dimer(D-D)and platelet(PLT)levels were monitored.The control group received conventional treatment,whereas the observation group was administered with low molecular weight heparin and fresh frozen plasma on the basis of conventional treatment.The aforementioned indicators were retested after 72 h of treatment.The clinical efficacy,coagulation function indexes and complication incidence of the two groups were compared.Results The effective rate of the observation group was significantly higher than that of the control group after treatment(P<0.05).No significant difference was observed in the levels of PT,APTT,FIB,TT,D-D and PLT between the two groups before treatment(all P>0.05).After treatment,the PT,APTT,TT and D-D levels of the observation group were significantly lower than those of the control group(all P<0.05).By contrast,the FIB level of the observation group was significantly higher than that of the control group(P<0.05).After treatment,the PLT level of the observation group was lower than that of the control group,but the difference was not statistically significant(P>0.05).After treatment,the levels of PT,APTT,TT and D-D in both groups were significantly lower than those before the treatment(all P<0.05).Furthermore,the level of FIB was significantly higher than that before the treatment(P<0.05).The levels of PLT in both groups after the treatment were significantly higher than those before thetreatment(P<0.05).After the treatment,the incidence of intracranial haemorrhage,gastrointestinal hemorrhage and pulmonary hemorrhage in the observation group was lower than that in the control group,but the difference was not statistically significant(all P>0.05).Conclusion Early intervention with low molecular weight heparin combined with fresh frozen plasma in the treatment of abnormal coagulation functions in critically ill newborns can improve clinical symptoms and restore coagulation functions.This intervention has good clinical effects.
