Preoperative anemia is a common finding among geriatric patients with trochanteric fractures. We assessed the dynamics of hemoglobin and the factors that influence it. A total of 780 patients with trochanteric fractures were selected. Distribution by gender showed a slightly higher proportion of female patients (64.1%). The preoperative interval ranged from a few hours to 19 days. Hospital admission period varied from 1 to 49 days. Hemoglobin ranged from 4.80 to 17.40 g/dl; 43.1% of patients had individual values below the baseline. Individually, the hemoglobin value varied from a decrease of 9.33 g/dL to an increase of 11.97 g/dL, but the total study group recorded an average decrease of 0.96 � 1.75 g/dL. Hemoglobin had a downward trend directly correlated with the preoperative interval period. Decrease in hemoglobin was correlated with the percentage of blood lymphocytes, PLT/WBC ratio, prothrombin activity and APTT ratio. A low level of hemoglobin variation was associated with a shorter preoperative interval, reduced prothrombin time, prothrombin activity ] 100, INR ] 1.50 and APTT ] 30.
