Abordaje del diagnóstico y tratamiento oportuno del síncope durante el embarazo.: Revisión de tres casos

Introduction: A syncope is a symptom that consists of the transitory loss of consciousness as consequence of a li-mited, relatively short and spontaneous inadequate supply of cerebral irrigation. The possible causes are numerous. Syncope and pre-syncope are prevalent in pregnancy; however, on many occasions the etiology it is not entirely well defined. The objective of this review is to determine the importance of the timely identification of the causes during pregnancy and its proper management to avoid adverse perinatal outcomes. Case series: The present study is a retrospective review of medical records of three patients with syncope. The first patient had cardiogenic syncope during pregnancy; the second presented a neurogenic syncope prior to gestation with an increase of episodes and the third patient had cardiogenic syncope during the first weeks of pregnancy. Conclusion: It is vital to establish a diagnosis and monitoring protocol to define the cause of syncope during preg-nancy and determine if there is a cardiac alteration that could complicate the mother or fetus during gestation, delivery or puerperium. Also, it must not be considered an isolated event related to hemodynamic changes or phy-siological effects during pregnancy. This will allow a better follow-up during prenatal controls and programming of the delivery according to established protocols, preventing complications to the mother and child
