The initial hemoglobin (Hb) levels and vital signs of 1,000 patients treated with intravenous infusion in the admission area of Groote Schuur Hospital Trauma Unit were recorded. The mean Hb level of 860 patients with mild or no signs of shock was 12.7 g/dL. Lower mean Hb levels were noted in 91 moderately shocked patients (11.8 g/dL, p less than 0.0001) and 49 severely shocked patients (9.9 g/dL, p less than 0.00001). In 140 patients with systolic blood pressure (SBP) under 80 mm Hg on… CONTINUE READING
