Medical literature has increasingly reported cases of maternal brain death during pregnancy. This is a rare situation which demands the decision and, depending on the gestational age, the implementation of a set of measures to prolong the homeostasis of the human body after brain death for the purpose of maintaining the foetus alive until its viability.
A 40 year old woman suffered an intracranial haemorrhage during the 25th week of pregnancy. Despite neurosurgical drainage of a gross intraparenchymatous haematoma, the patient developed brain death. Upon confirmation of this diagnosis, she received full ventilatory and nutritional support, vasoactive drugs, maintenance of normothermia, hormone replacement and other supportive measures required to prolong gestation and improve the survival prognosis of her foetus. All decisions regarding the patient's treatment were taken in consensus with her family. She also received corticosteroids to accelerate foetal lung maturity. During the twenty-five days of somatic support, the woman's condition remained stable; however, during the last seven days the foetus developed oligohydramnios and brain-sparring, which led the medical team to take the decision to perform a Caesarean section at that moment. After delivery, the patient's organs were removed for donation. The male infant was born weighing 815 g, with an Apgar score of 9 and 10 at the first and fifth minutes, respectively. The infant was admitted to the neonatal intensive care unit, but did not require mechanical ventilation and had no major complications. He was discharged at 40 days of life, with no sequelae and weighing 1850 g.
These results are in accordance with findings from previous studies and case reports suggesting the appropriateness and safety of extended somatic support during pregnancy under certain circumstances. They also suggest the need for prompt diagnosis of brain death before the occurrence of physiological degeneration, rapid evaluation of foetal status and the decision of the family together with the medical team to prolong maternal somatic support. The occurrence of maternal brain death is a tragedy, but it may also represent a challenging opportunity to save the life of the foetus and, in addition, permit donation of the maternal organs.
医学文献越来越多地报道了孕期母亲脑死亡的病例。这是一种罕见的情况,需要做出决策,并根据孕周实施一系列措施,以在脑死亡后延长人体的内环境稳定,目的是维持胎儿存活直至其具备生存能力。
一名40岁女性在怀孕第25周时发生颅内出血。尽管对巨大的脑实质内血肿进行了神经外科引流,但患者仍发展为脑死亡。确诊后,她接受了全面的通气和营养支持、血管活性药物治疗、维持正常体温、激素替代以及延长孕周和改善胎儿生存预后所需的其他支持措施。关于患者治疗的所有决策均与她的家人协商一致做出。她还接受了皮质类固醇以加速胎儿肺成熟。在进行躯体支持的25天里,该女性的病情保持稳定;然而,在最后7天,胎儿出现羊水过少和脑保护现象,这导致医疗团队决定此时进行剖宫产。分娩后,患者的器官被摘除用于捐赠。男婴出生时体重815克,1分钟和5分钟时的阿氏评分分别为9分和10分。婴儿被送入新生儿重症监护病房,但无需机械通气,也没有重大并发症。他在出生40天时出院,无后遗症,体重1850克。
这些结果与先前的研究和病例报告结果一致,表明在某些情况下孕期延长躯体支持的合理性和安全性。它们还表明需要在生理退化发生之前迅速诊断脑死亡,快速评估胎儿状况,以及家庭与医疗团队共同决定延长母亲的躯体支持。母亲脑死亡的发生是一场悲剧,但它也可能是拯救胎儿生命以及此外允许捐赠母亲器官的一个具有挑战性的机会。
