Role of Base Deficit in Resuscitation of Polytraumatized Patients Presented by Hypovolemic Shock

The current ATLS system was designed for the initial management of severely injured trauma patients and has become the unofficial gold standard worldwide. Delayed treatment of hypovolemic shock leads to adverse outcomes, such as organ dysfunction and increased mortality Thus, for each class of shock (class I to IV), ATLS recommends a specific requirement (crystalloid ± blood) to manage the presumed level of hemorrhage. However, The ATLS classification system may not accurately reflect the degree of hemorrhage. These findings suggested that the current system may overestimate the degree of tachycardia in relation to hypotension and underestimate mental status changes thus enhances us to develop new method for classification of hemorrhagic shock as regard metabolic markers as base deficit. Aim of the present study: To know the prognostic significance of post trauma base deficit and to validate base deficit based classification in polytraumatised patients presented by hypovolemic shock.
