对孕妇进行了5,000次以上静注葡萄糖耐量试验(GTT),查出化学性糖尿病约500例。大约80%病人产后6周复查GTT恢复正常。作者于产后6个月再给这些病人作葡萄糖耐量试验,并注意避孕药物的影响。用静注葡萄糖25克糖耐量试验,并用增加指数(increment index,II)来表示。结果小于2.97者为“不正常”。同时给病人以联合小剂量避孕药(Eug- More than 5,000 intravenous glucose tolerance tests (GTT) were performed on pregnant women and about 500 cases of chemical diabetes were detected. Approximately 80% of patients return to normal after 6 weeks of retesting for GTT. The authors gave these patients glucose tolerance test 6 months after delivery, and pay attention to the impact of contraceptives. An intravenous glucose 25 g glucose tolerance test was used and expressed as an increment index (II). If the result is less than 2.97, it is “abnormal”. At the same time to patients with combined low-dose contraceptives (Eug-
