Comportamiento del exceso de base, lactato y saturación venosa en pacientes con Choque hipovolémico hemorrágico por trauma atendidos en el Servicio de Urgencias del Hospital General Balbuena

Abstract

Traumatic injuries have a high impact on our society and its treatment requires extensive knowledge, skills and a high index of suspicion for the early detection of serious injury. The shock is an entity that is presented common in patients with trauma, with the advent of various diagnostic modalities is to attempt to detect the shock diagnosis and severity of early. The aim of this study was to determine the behavior of the leading global markers of perfusion in various degrees of shock. Methods: a clinical, retrospective, observational, cross sectional, which was held at the General Hospital Balbuena, were selected in 38 patients admitted to the emergency department at the General Hospital Balbuena of March 1, 2010 to September 30, 2010 with a diagnosis of hemorrhagic hypovolemic shock trauma at any level according to the CAC, demographic data were collected through the record collection to determine the degree of shock, the values of blood gases, lactate, base excess and saturation vein, as well as the mechanism involved in the etiology of the traumatic event and the anatomical site injured. Results: Of the 38 patients the highest percentage in the degree of shock was found in grade III (48%) as to the levels of lactate values were between "2.6 to 3.5" and "3.6 to 4.5 "corresponded to the highest percentages (30 and 32% respectively), the base excess was found to group" Under - 6 "37%" and as for venous congestion group "65 to 67 "found at a rate of 32%. Conclusions: The hypovolemic shock is an entity that often accompanies trauma patients, known as tissue perfusion markers are directly related to the severity of shock in grades determined by the CAC, including lactate and base excess, not so much venous saturation. Keywords: shock, lactate, base excess, venous saturation.
