ABSTRACT

Objective: To evaluate the amount of blood drawn for diagnostic tests in critically ill patients.
Design: Prospective and observational study.
Setting: ICU of a Military Hospital in Mexico City.
Patients: A total of 186 patients were enrolled in this study.
Interventions: None.
Measurements and main results: A mean value of 45 mL a day was drawn, and the total volume drawn during their ICU stay was 180.2 mL of 79 patients who received transfusions had a decrease of hemoglobin from 11.4 ± 0.18 g/dL to 10.9 ± 0.13 g/dL (p ‹ 0.001). Patients who did no received transfusions had 12.3 ± 0.24 vs 11.4 ± 0.15 g/dL of hemoglobin (initial and final values, respectively); p ‹ 0.001. The cost of laboratory tests was near of (500 US dollars)/day.
Conclusion: ICU patients had large losses from phlebotomy and the cost of laboratory tests is expensive.
