    Abstract:
    OBJECTIVES: Reservation of dedicated series of pedipacks, consisting of 3 to 4 units of 70 ml filtered red cell concentrate in additive solution SAGM from 1 donor, may reduce donor exposure. In this prospective efficacy study the benefits, release and expiration of pedipacks (PP) assigned to preterm infants requiring neonatal intensive care are analyzed. METHODS: On the basis of clinical assessment of the need for multiple transfusions, 96 preterm neonates (gestational age < 32 wks and/or birth weight < 1500 g) were assigned to either the high risk group (HRG), who were to receive dedicated donor blood units, or the low risk group (LRG). Inclusion criteria for HRG were 1) estimated time of admission > 21 days and 2) expected need for multiple transfusions due to clinical cardiorespiratory instability, prolonged parental feeding or frequent blood sampling. To reduce wastage of donor blood, dedication of donor blood units was limited to 21 days. RESULTS: 50 series (192 PP) were assigned to 42 HRG infants. Two HRG infants received 3 series, 4 received 2 series and 36 received 1 series of PP. Mean transfusion rate was 3.1 PP in the HRG and 0.4 in the LRG. In the LRG 35 of 54 were not transfused, 19 received 1 to 2 PP. In both groups transfused newborns were exposed to 1.1 donors in average. In the HRG of 192 PP, 137 PP (71%) were used within 21 days, and another 30 (16%) before the expiration date < 35 days. Twenty five PP (13%) expired, mainly because of logistical problems in the introduction phase. CONCLUSION: Assignment of dedicated PP on the basis of clinical parameters at entry considerably reduces donor exposure in HRG. Wastage of dedicated blood transfusions was reduced by limitation of the dedicated period (21 days). In terms of efficacy, reservation and use of PP can be optimized by standardized administrative measures.
