Predictive value of uterine Doppler waveform during pregnancies complicated by diabetes.

Diabetes, whether or not it is insulin deficient, is frequently associated with vascular complications during pregnancies. It is accepted nowadays that the uterine artery velocity waveform is predictive concerning pregnancy-induced hypertension (PIH) and its complications. It thus seemed interesting to analyse the predictivity of vascular complications of diabetes by using uterine artery velocity waveforms. We have thus explored 37 diabetic patients [group 1: insulin-deficient diabetes (IDD), n = 10; group 2: gestational IDD, n = 6; and gestational non-IDD, n = 21). We have found vascular complications for 10 patients, divided between all 2 groups: 2 pre-eclampsia, 2 fetal suffering before any labour, 2 cases of intra-uterine growth retardation (including a trisomy 18) and 5 PIH. The uterine artery velocimetry measurement has been found to be pathological 5 times, and always in patients who later developed vascular complications. Among this selected population and excluding the trisomy 18, the sensitivity is of 44.5%, the specificity of 100%, the positive predictive value of 100%, and the negative predictive value of 84.3%. If these results are confirmed, this examination could be an excellent marker of the vascular risk and thus would have its place during systematic survey of pregnancies complicated by diabetes.

[The lecithin-sphynogomyelin ratio in the amniotic fluid in insulin dependent diabetic pregnancies].

A delay in the pulmonary maturation of the foetus of diabetic mothers assessed by the lecithin-sphingomyelin (L/S) ratio has been reported (2, 3, 5). A suggestion has been raised that the results of the L/S ratio should be viewed with caution in predicting lung maturity in pregnancies complicated by maternal diabetes (8). We report our findings on 52 insulin-dependent diabetic pregnancies which involved 90 estimations of the L/S ratio on the amniotic fluid. In all cases, the L/S ratio accurately reflected lung maturity, as no hyaline membrane disease (HMD) was observed with a L/S ratio greater than 2. There was no significant difference in the proportion of mature fetal lung between insulin-dependent diabetics and controls for each week of pregnancy between 32 and 38 weeks. There is no statistical difference in the mature L/S ratio between classes B + C and D + F diabetics.

Risk/benefit ratio of changing late obstetrical strategies in the management of insulin-dependent diabetic pregnancies. A comparison between 1971-1977 and 1978-1985 periods in 389 pregnancies.

We compared the results of 166 pregestational insulin dependent diabetic pregnancies in the period 1971-1977 to those of 223 in the period of 1978-1985, after the introduction of self monitoring of blood glucose. During this second study period late obstetrical strategies changed to prolongation of pregnancy up to term, avoidance of final hospitalization and decrease of the rate of cesarean section. Maternal blood glucose control was less optimal in the second period resulting in a higher incidence of fetal macrosomia. Despite this, unexplained stillbirth disappeared, neonatal morbidity did not change significantly and the overall benefit was a reduction of preterm birth and a better quality of life for our patients. We conclude that the final hospitalization from week 32 onward in insulin dependent diabetic pregnancies is no more mandatory.

[Cerebral symptoms in the term newborn infant. Results of a prospective survey].

1785 newborns of 37 weeks GA or more, were studied during a 15 months period at the Port-Royal Maternity Hospital. This study suggests that cerebral abnormalities during the neonatal period in fullterm neonates are related to deleterious intra partum factors. In 57 newborns, clear cut signs of cerebral birth injury were observed, in 31 newborns only mild and transitory signs were observed. These 88 newborns were compared with 1655 having had a normal neurological examination within the first week of life. We focused particulary on dysfunctional labor patterns, specifically false labor, protracted active phase dilatation, protracted descent or a marked caput succedaneum. When these abnormal patterns are followed by oxytocin infusion and forceps extraction, primiparity appears linked with a high risk of cerebral birth injury. Within cephalic presentations, the occipito-posterior position is carrying the same high risk. The most severe degree of cerebral birth injury has nearly disappeared. However, the main problem of modern obstetrics is one of eradicating brain damage of moderate degree without reaching an excessive incidence of C. section.
