Postoperative vasoplegic syndrome (VS) was first described by Arkin in 1977 as a hemodynamic state that occurs immediately after the cardiopulmonary bypass (ECC) system, which was characterized by low blood pressure, normal to high cardiac output, and vascular resistance. low systemic. Currently, it is a clinical entity that has been gaining importance due to the increase it causes in morbidity and mortality in the postoperative period of cardiac surgery. The classic definition
of vasoplegic syndrome consists of a clinical state characterized by hypotension, low systemic vascular resistance, and increased fluid and vasopressor requirements. The associated factors are multiple, but the central axis is located in the exaggerated inflammatory response to the powerful stimulus that extracorporeal circulation represents and the fact that this response presents a marked interindividual variability, which suggests genetic characteristics as a possible factor predisposing. The preoperative use of angiotensin converting enzyme inhibitors and the mean arterial pressure at the extracorporeal circulation are potentially controllable risk factors, or if the patient presents with them, consider the treatment or prevention of vasoplegia. Treatment focuses on asoconstrictors, which can be divided into: catecholamines, hormones, nitric oxide inhibitors (methylene blue), therapeutic scheme. The general approach of this work is to present the Vasoplegic Syndrome in Cardiac Surgery, its main symptoms, risk factors and treatments. The results were obtained through the
development of a bibliographic research, limited to a review methodology, which allows to conclude that even though this condition is potentially reversible if it is treated when observing the first symptoms, it is necessary to develop studies that determine the most suitable conditions to initiate the administration of the treatment, the appropriate time and range of dosage and its subsequent effects.. |
