HELLP syndrome may lead to disseminated intravascular coagulation (DIC) which can make emergency surgery a serious challenge. A 29-year-old female presented with haematuria, epistaxis and hypertension in the emergency ward and a diagnosis of DIC complicating HELLP in preeclampsia was made. She had continuous epistaxis and elective tracheal intubation was carried out. During emergency caesarean section the patient was managed with blood products, antihypertensive drugs and general anaesthesia together with invasive monitoring. She required postoperative ventilatory support. HELLP syndrome may progress to DIC in 15-38% of patients. The prothrombin time, activated partial thromboplastin time and serum fibrinogen levels are normal in HELLP syndrome but are prolonged in DIC. Evaluation of more sensitive markers of DIC, such as antithrombin III, α-2 antiplasmin, plasminogens, fibrin monomer and D-dimers, differentiates DIC from HELLP syndrome. Aggressive treatment is indicated and delivery should be expedited, by caesarean section if necessary although vaginal delivery is not contraindicated, along with control of blood pressure and coagulation abnormality. We conclude that patients with DIC complicating HELLP syndrome and preeclampsia require great vigilance and multimodal management in the perioperative period for uneventful outcome.
HELLP综合征可能导致弥散性血管内凝血(DIC),这会使急诊手术成为一项严峻挑战。一名29岁女性在急诊病房出现血尿、鼻出血和高血压,诊断为子痫前期合并HELLP综合征并发DIC。她持续鼻出血,遂进行了择期气管插管。在急诊剖宫产手术期间,患者接受了血液制品、降压药物和全身麻醉治疗,并进行了有创监测。术后她需要通气支持。15% - 38%的HELLP综合征患者可能进展为DIC。HELLP综合征患者的凝血酶原时间、活化部分凝血活酶时间和血清纤维蛋白原水平正常,但在DIC时会延长。评估DIC更敏感的指标,如抗凝血酶III、α-2抗纤溶酶、纤溶酶原、纤维蛋白单体和D-二聚体,可将DIC与HELLP综合征区分开来。应进行积极治疗,必要时通过剖宫产加快分娩,尽管阴道分娩并非禁忌,同时要控制血压和凝血异常。我们得出结论,子痫前期合并HELLP综合征并发DIC的患者在围手术期需要高度警惕和多模式管理,以确保获得良好的预后。
