Abstract
Restrictive transfusion criteria have led to decreased morbidity and mortality in critically ill patients. Their use has been extended to other patient groups. In adult spine surgery, ongoing postoperative blood losses and soft-tissue trauma may make these patients not appropriate for restrictive transfusion practices. The purpose of this study was to assess the influence of postoperative hemoglobin (HGB) level and use of packed red blood cells (pRBC) or fresh frozen plasma on postoperative patient morbidity, mortality, and hospital length of stay (LOS). This was a retrospective study in a high-volume tertiary hospital. The sample comprised 300 consecutive patients who underwent spinal surgeries with blood losses of more than 2 L. The outcome measures were postoperative patient morbidity, mortality, and LOS. The records of patients who underwent adult spinal surgeries with blood loss of 2 or more L (N=300) were abstracted for patient characteristics, operative characteristics, transfusion, and HGB level over time. Intensive care unit and hospital LOS, discharge location, death, pulmonary embolism, stroke, seizures, surgical site infections (SSI), and myocardial infarctions were noted. Logistic regression analyses (SAS software ...Continue Reading
