Predictive Value of Base Deficit in Outcomes of FAST Positive Patients with Multiple Trauma

Background: Decreased tissue perfusion is a predictor of mortality in trauma patients, and measured by serum lactic acid, which isn’t possible at all centers. The reduction of Base Deficiency (BD) in trauma patients is mainly due to lactic acidosis. We sought to assess the predictive value of base deficit in outcomes of FAST positive patients with multiple trauma.Methods:  In this study, ۸۸ trauma patients were referred to the emergency department with acute abdomen reqiuring surgery. Free intra-abdominal fluid on fast ultrasound, abdominal injury on CT scan, and candidates for either surgery or non-operative management, and their data were statistically analyzed.Results: Out of ۸۸ participants, eight patients (۹.۱%) died, and ۲۴ of them (۲۷.۳%) required surgical intervention. Mortality rate and hospitalization days increased with increasing BD (P = ۰.۰۰۱), but the increase in mortality rate and BD increase did not show a significant relationship. The best BD cut-off point for predicting the need for surgery in patients was BD> ۴.۴۵ (sensitivity ۷۹.۲% and specificity ۶۵.۶%).Conclusion: BD predicts the need for surgery and the length of hospital stay. Because a low number of deaths in our study, we suggeste that further studies be done with a larger statistical populations.
