Red blood cell transfusion in perioperative pediatric anesthesia: a survey of current practice in Germany.

<bold>Background: </bold>Little is known about the current practice of the perioperative transfusion of red blood cells (RBCs) in pediatric patients. This study was performed to evaluate the practice of RBC transfusion in German pediatric anesthesia.<bold>Study Design and Methods: </bold>An online survey was conducted among members of the German Society of Anesthesiology and Intensive Care. Participants were asked to indicate the hemoglobin (Hb) thresholds for starting RBC transfusion in six cases of different bleeding situations in pediatric anesthesia. Demographics of participants, general knowledge, and application of transfusion rules and guidelines were assessed.<bold>Results: </bold>We included 1207 of 1396 returned questionnaires. Of the respondents, 89% were qualified specialists and 68% had experience in anesthesia in children aged less than 6 months. The lowest median Hb transfusion threshold was 6 g/dL in a 16-year-old and the highest was 10 g/dL in a premature neonate. Intraoperative Hb thresholds increased for clinically unstable (median difference to clinically stable children, +1 g/dL; p < 0.001) or neonate and premature children (median difference to older children, +1 and +2 g/dL; p < 0.001). The stated Hb threshold ranges were broad, especially in neonates or premature children (interquartile range, neonates 3, premature children 4 g/dL). Of the participants, only 16% had knowledge of a guideline that includes blood transfusion in children.<bold>Conclusion: </bold>Striking variability exists in practice of perioperative pediatric RBC transfusion. A specialized guideline for perioperative blood transfusion in children could be helpful to define and promote optimal pediatric RBC transfusion strategies. [ABSTRACT FROM AUTHOR]
