ABSTRACT
BACKGROUND: Although transfusion in neonates needs to be strictly regulated due to the vulnerability of neonates, there is lack of systematic studies and the working process is not well-established. This study was aimed to point out the problems of current status and to improve the efficiency of systems used in blood aliquots for neonatal transfusions. METHODS: Total red blood cell (RBC) aliquots were analyzed between May 2009 and January 2016 in the neonate intensive care unit. We investigated the aliquot number, issued day interval from the first issued aliquot among the post-aliquots, patients' blood type, and discarded RBC units among the requested RBC units. RESULTS: Of the 472 RBC aliquots, 95.4% (450/472) were divided into two units. The distribution of patients' blood type was similar to that of the Korean population, in decreasing order: A blood group (34.3%), B group (28.2%), and O group (27.5%). The second, third, and forth units of post-aliquots were taken after an average of 49.9 (0∼617.9) hours. Among the post-aliquots, the number of units discarded without use was 22.5%. CONCLUSION: According to the evaluation of current status for neonatal transfusions, we should use aliquot RBC properly and reduce unnecessary requests for aliquot RBC. In addition, in order to reduce the number of near misses, we propose a new label to be attached on the aliquotted blood bags and suggest a development of electronic blood issuing system.

Introducción: la eritropoyetina alfa recombinante forma parte del tratamiento de la anemia de la prematuridad. En Cuba su uso ha sido limitado y controvertido en cuanto a esquema y dosis empleada. Métodos: ensayo clínico prospectivo, multicéntrico, no aleatorizado, de eficacia y seguridad de eritropoyetina en la disminución de transfusiones en el recién nacido pretérmino de muy bajo peso. Se incluyeron 72 neonatos con edad gestacional menor de 34 semanas posmenstruales, y peso al nacer menor o igual a 1 500 g, con más de 7 días posnatales e ingesta de 50 mL/kg/día. Resultados: todos recibieron eritropoyetina 300 U/kg, subcutánea, 3 veces/semana, hasta las 40 semanas de edad gestacional y suplemento de hierro y vitaminas. La eritropoyetina fue muy segura, solo se notificó con relación posible una retinopatía de la prematuridad, ligera y recuperada. Conclusiones: se transfundieron 7 pacientes (9,7 por ciento) en el curso del estudio. El uso tardío de eritropoyetina en el pretérmino de muy bajo peso confirma su eficacia y seguridad
Introduction: recombinant alpha erythropoietin is part of the treatment for anemia of prematurity. The use of this one in Cuba has been restricted and controversial as to schedule and dose. Methods: prospective, non-randomized multicenter assay on the safety and efficacy of erythropoietin in the reduction of blood transfusion in very-low-weight preterm newborn. Seventy two neonates with gestational age under 34 post-menstruation weeks, weighing equal or less than 1 500 g, over 7 days of life after birth and fed on 50 mL/kg/day were included in the study. Results: all of them received 300 U/kg erythropoietin by subcutaneous administration three times a week up to reaching 40 weeks of gestational age and an iron and vitamin supplement. Erythropoietin is very safe; it was just possibly related to slight retinopathy of prematurity, but overcome. Conclusions: seven patients were transfused (9.7 percent ) in the course of study. The late use of erythropoietin in very-low-weight preterm child confirms its efficacy and safety
