In order to known the incidence of unsuspected bacteremia in our area and to determine the usefulness of the laboratory tests to identify children with such pathology, a prospective study was designed including 61 infants between 3 and 24 months of age admitted to our emergency room with fever of 39 degrees centigrade or more, without apparent focality or respiratory symptoms. All underwent blood culture, complete blood count and C-reactive protein plasma levels determination. No positive blood cultures were obtained. The relation bands/total neutrophils greater than 0.15 with leucocytosis or neutrophilia was not found in any child, and leucopenia was found in only one. We conclude that occult bacteremia is not present in our milieu amongst children who fit into the risk factor criteria defined by TEELE et al. and that it might be convenient to include a fever of less than 24 hours as a risk factor in order to exclude many children with fever and a clear focality.
为了解我们地区未被怀疑的菌血症发病率，并确定实验室检查对识别患有此类病症儿童的有用性，我们设计了一项前瞻性研究，纳入了61名3至24个月大的婴儿，这些婴儿因体温39摄氏度或更高被送入我们的急诊室，无明显病灶或呼吸道症状。所有婴儿均接受了血培养、全血细胞计数和C反应蛋白血浆水平测定。未获得阳性血培养结果。在任何儿童中均未发现带/总中性粒细胞大于0.15且伴有白细胞增多或中性粒细胞增多的情况，仅在一名儿童中发现了白细胞减少。我们得出结论，在符合TEELE等人定义的危险因素标准的儿童中，我们所处环境中不存在隐匿性菌血症，并且为了排除许多有发热且有明确病灶的儿童，将发热时间少于24小时作为危险因素可能是合适的。
