本文通过检测78例危重新生儿的血糖及胰岛素水平，发现78例危重新生儿高血糖发生率为74％，高胰岛素血症占67％，两者升高程度与疾病的危重程度呈正相关。低血糖与低胰岛素血症虽占比例较少，但与疾病危重程度也密切相关。我们认为密切观察危重新生儿的血糖与胰岛素水平，可作为判断预后的一项条件。 In this paper, 78 cases of critically ill newborns blood glucose and insulin levels were detected and found that 78 cases of critically ill neonatal hyperglycemia was 74%, hyperinsulinemia accounted for 67%, both elevated and the severity of the disease was positively correlated. Hypoglycemia and hypoproteinemia, although less proportion, but also with the severity of the disease are also closely related. We believe that close observation of critically ill newborns blood glucose and insulin levels can be used as a condition to judge the prognosis.
