Objective:
To study the fetal developmental regulation and gestational weeks at labor for triplets pregnancies.
Methods:
To detect biparietal diameters and femoral length at different gestational weeks, record gestational weeks of labor and birth weights, and compare with those of singletons.
Results:
The fetal development of triplets slowed down from the beginning of the 28th gestational week compared with that of singletons (the mean difference was 2.1 mm and 3.1 mm respectively, P < 0.01, P < 0.01). Birth weights of 36.2% triplets was less than that of the 10th percent of the same singletons gestational week. 95.7% triplets delivered their babies before 36 weeks. The average gestational week was 34.0 +/- 1.6, obviously ahead of the singletons'.
Conclusion:
The fetal developmental regulation of triplets pregnancies is different from that of singletons, the gestational period is shorter than those of twins and singletons.
