In recent years, data has emerged using goal directed therapy in the surgical patient population with favorable outcomes suggesting a decrease in post-operative organ dysfunction, ICU and hospital length of stay, however, there is limited data in the trauma patient population. This study endeavors to determine if the implementation of intra-operative monitoring will decrease the incidence of post-operative complications such as acute lung injury, infections, thromboembolism, cerebral vascular accident, acute kidney injury, myocardial infarction; in addition to the traditional outcome measures of mortality and length of stay.
