Non-stress test changes during acupuncture plus moxibustion on BL67 point in breech presentation.

OBJECTIVES: We assessed fetal heart variability and activity using a computerized non-stress test (NST) during acupuncture plus moxibustion on the BL67 point. For comparison, the same changes were assessed during placebo acupuncture (minimal acupuncture) in the same subjects. METHODS: Twelve pregnant women in the 33rd week of gestation, carrying singletons in the breech presentation were enrolled in the study. In a single-blind design, each woman received a first session of minimal acupuncture followed 1-2 days later by true acupuncture. During the sessions, women were monitored using computerized non-stress testing starting 20 minutes before the stimuli and continuing for 20 minutes after treatment. RESULTS: During true acupuncture a significant reduction in fetal baseline heart rate, and more accelerations and movement were observed. During minimal acupuncture, there were no significant changes in these variables. No signs of fetal distress or changes in short- or long-term variability were noted, and there were no uterine contractions. CONCLUSION: In our study population, acute application of acupuncture plus moxibustion did not cause fetal distress as assessed by either fetal heart rate decelerations or changes in either short- or long-term variability. Considering that the modifications in fetal movement and heart rate occurred in true but not during minimal acupuncture, we could consider that such changes are related to the effect of the acupuncture stimulation. The mechanisms leading to the cephalic version remain to be clearly established.

C-peptide and insulin levels at 24-30 weeks' gestation: an increased risk of adverse pregnancy outcomes?

OBJECTIVE: The hypothesis was that fasting C-peptide and insulin values, during an oral glucose tolerance test (OGTT), might allow an estimation of the increased risk for gestational hypertension (GH) and fetal macrosomia. STUDY DESIGN: Two-hundred and six consecutive patients were submitted to an OGTT. Thirty-five developed gestational hypertension and 29 delivered large-for-gestational-age (LGA) newborns. Plasma glucose levels (mg/dl) and insulin levels (microU/ml) were measured fasting and after 60, 120 and 180 min C-peptide fasting levels (ng/ml) were also measured. RESULTS: Twenty-five patients were excluded, 181 were enrolled. According to the OGTT, 143 patients were classified as normal, 26 were found affected by gestational diabetes (GD) mellitus, and 12 had impaired gestational glucose tolerance (IGGT). Hypertensive women exhibited higher 60 and 120 min insulin values than the normotensive group (128.3+/-69.9 microU/ml versus 86.2+/-58.3 microU/ml, P<0.05; 104.9+/-66.4 microU/ml versus 78.7+/-56.5 microU/ml, P<0.05).C-peptide cut-off at 2.9 ng/ml resulted predictive for patients delivering large-for-gestational-age newborns (OR=3.42, 95% CI=1.59-7.39). CONCLUSIONS: C-peptide and insulin may be used as indicators of risk for the development of complications in late pregnancy.
