The reproductive risk potential of prolonged gestation.

This paper divides, reviews, and describes the relationships among the important issues involved in prolonged gestation and the inherent potential for reproductive risk. The prevalence and significance of the problem is illustrated through comparison of recent reports. Possible physiologic and psychologic contributing factors are discussed including hypothesized etiology as well as recognized associated events. The relationship of prolonged gestation to fetal postmaturity is discussed in pathophysiologic detail. The effects of postmaturity on the developing child with implications for follow‐up are also presented. Assessment of fetal and neonatal status for the purpose of risk identification develops the theme of reduction of reproductive casualties during this period. Finally, the nursing implications are discussed at the primary and secondary perinatal settings, with emphasis on maintaining psychologic and physiologic equilibrium.
