Absence of evidence of pulmonary maturity at amniocentesis in term infants of diabetic mothers.
A total of 153 patients' charts were reviewed over a 6-year period to assess the results of the practice of amniocentesis for diabetic mothers at term (greater than or equal to 37 weeks' gestation) before elective induction/delivery. The number of cases with absent phosphatidylglycerol were determined at each specific gestational age at or near term. Phosphatidylglycerol was present in 130, and phosphatidylglycerol was absent in 23 at first amniocentesis sampling. A significant proportion (approximately 21%) of those with gestational diabetes were phosphatidylglycerol-negative as late as 38 weeks' gestation. A similar proportion of overt diabetic patients were phosphatidylglycerol-negative as late as 39 weeks' gestation. These figures give the clinician some estimate of the likelihood of the absence of phosphatidylglycerol at or near term if amniocentesis is used before elective delivery in these patients.
