ABSTRACT

Avaliou-se o hemograma e a morfologia celular em amostras de sangue periférico obtidas de 10 peixes da espécie Oreochromis niloticus. Parte das mesmas foi utilizada para o estudo da hematimetria, isto é, contagem de eritrócitos (x = 2,35 x 10 elevado à sexta potência/mm ao cubo mais ou menos 0,12), taxa de hemoglobina (x = 7,04g/dL mais ou menos 0,38), hematócrito (x = 27,85 por cento mais ou menos 1,62), HCM (x = 30,31pg mais ou menos 1,64), VCM (x = 118,6u ao cubo mais ou menos 3,53), CHCM (x = 25,78 por cento mais ou menos 1,72), contagem global de leucócitos (x = 16,08 x 10 ao cubo/mm ao cubo mais ou menos 1,28), contagem de trombócitos (x = 61,69 x 10 ao cubo/mm ao cubo mais ou menos 5,96), sendo a avaliaçäo da morfologia das células do sangue realizada através do estudo de extensöes sanguíneas submetidas à coloraçäo de Wright. Os eritrócitos e trombócitos nucleados apresentaram-se elípticos; neutrófilos e eosinófilos esféricos de tamanho variável, com o núcleo também esférico, apresentaram citoplasmas abundantes, ligeiramente basófilo e altamente acidófilo, respectivamente. Näo foram vistas as formas polimorfonucleares dessas células. Os basófilos apresentaram núcleo esférico e granulaçöes metacromáticas. Os monócitos e os linfócitos assemelharam-se morfologicamente aos dos mamíferos

ABSTRACT

In order to assess the nutritional status of children with heart diseases and to evaluate nutritional parameters for predicting postoperative complications, 50 children undergoing to cardiac surgery and classified in high and low surgical risk prospectively evaluated. Assessment parameters included anthropometry and plasma proteins albumin, transferrin and prealbumin. The nutritional classification according to Waterlow's modified criteria showed a high prevalence of malnutrition in the population studied (78%). The measures of arm circumference when located below the 5th percentile showed a significant association with general postoperative complications in the high risk group (arm circumference, p = 0.0019; arm muscle circumference, p = 0.0419). The percentage of weight per height, serum albumin and transferrin has not played a prognostic role concerning postoperative morbidity. The mean value of prealbumin was significantly lower in high risk group patients developing postoperative infections (p < 0.01) compared to those who did not. The sensitivity-specificity analysis of prealbumin as risk indicator for postoperative infection was 87.5% and 59% respectively. The nutritional risk classification seems to be a good way to identify the subgroups of children with additional postoperative surgical risk. However, more specific and sensitive tests are desirable to provide an individual identification of these children.
