Resumo
JUSTIFICATIVA E OBJETIVOS: As indicações de transfusão de eritrócitos não estão bem estabelecidas em crianças gravemente enfermas. O objetivo deste estudo foi descrever a prática da transfusão de eritrócitos na UTI Pediátrica do Hospital de Clínicas da Universidade Estadual Paulista (HC-UNESP). MÉTODO: Estudo retrospectivo observacional realizado durante o ano de 2003. RESULTADOS: Setenta e cinco pacientes receberam transfusão, havendo registro de 105 indicações. Mais da metade dos pacientes (53,3%) tinha menos que um ano de idade. Taquipnéia (75,2%), palidez (65,7%) e hipotensão (51,4%) foram os registros mais freqüentemente observados antes da transfusão. Além disso, a gasometria evidenciou acidose metabólica (68,08%) e hipoxemia (63,8%). Dos 93 registros de valores de hemoglobina (Hb), 54 (58,1%) estavam entre 7 e 10 g/dL e dos 90 registros de hematócrito (Ht) observou-se que 66 (73,3%) apresentavam valores entre 21% e 30%. As principais indicações de transfusão foram anemia em 75 crianças (71,4%) e sangramento ativo em 26 (24,7%). O valor médio de Hb antes da transfusão foi de 7,82 ± 2,82 g/dL. Sete transfusões foram indicadas para pacientes com valores de Hb > 10 g/dL, crianças estas em pós-operatório imediato de intervenção cirúrgica cardíaca e casos de choque séptico. CONCLUSÕES: A transfusão de eritrócitos vem sendo utilizada criteriosamente, com indicações restritivas (Hb entre 7 e 10 g/dL). Nem sempre há anotação dos valores de Hb imediatamente antes da transfusão. A partir deste estudo, foi elaborado um protocolo de indicação de transfusão na unidade.
BACKGROUND and OBJECTIVES: Indications of red blood cell transfusion in critically ill children are not very well determined. This study aims to describe red blood cells transfusion practice at the PICU of UNESP-Botucatu Medical School. METHODS: Retrospective observational study of all patients who received transfusion during 2003. RESULTS: Seventy five patients received transfusion and 105 indications were recorded. 53.3% of the patients were less than one year of age. Increased respiratory rate (75.2%), paleness (65.7%), and hypotension (51.4%) were the alterations more frequently recorded, before transfusion. Also, metabolic acidosis (68.08%) e and hipoxemia (63.8%) were very frequently observed. From 93 hemoglobin (Hb) values recorded, 54 (58.1%) varied from 7 to 10 g/dL and from 90 records of hematocrit (Ht) 66 (73.3%) varied from 21% to 30%. The main indications of the transfusion were anemia, in 75 children (71.4%), and active bleeding in 26 (24.7%). The mean value of Hb before transfusion was 7.82 ± 2.82 g/dL. Seven transfusions were indicated for patients with Hb levels higher than 10 g/dL (postoperative heart surgery and septic patients). CONCLUSIONS: red blood cells transfusion is carefully prescribed at the PICU by using restrictive indications (Hb between 7 and 10 g/dL). Not always is possible to find out records of the Hb levels immediately before transfusion. Hence, a protocol to better prescribe red blood cell transfusion at the PICU was adopted.
