Índice de shock como marcador inicial en el manejo de pacientes con shock hemorrágico

Abstract

Abstract: Hemorrhagic shock is one of the leading causes of preventable death in trauma patients. It is a form of hypovolemic shock in which intense bleeding leads to insufficient oxygen supply at the tissue level. Its early identification remains difficult at the outpatient and hospital level, causing under-triage and improper transfer. In recent years the shock index (SI) has been suggested as a marker that can be used to predict the severity of hypovolemic shock. It is defined as the heart rate divided by the systolic blood pressure. Currently the most widely used cut-off point is the 0.9 range. The objective of this article is to carry out a bibliographic review of the literature to determine the impact of the shock index as an initial marker in the management of patients with hemorrhagic shock. Previous studies of meta-analysis, cases and controls, retrospective cohorts, and reviews were used. systematic. It was determined that a shock index above this 0.9 increases the risk of hypovolemic shock and subsequently the probability of requiring a blood transfusion.
