Abstract
Smoking a standard cigarette caused an acute decrease in intervillous placental blood flow. This change normalized within 15 minutes. At the time intervillous blood flow was depressed, heart rate and blood pressure were elevated and remained so throughout the study period. Repeated decreases in the intervillous blood flow could explain growth retardation of the fetus and some other complications of pregnancy in women who smoke.
摘要
吸一支标准香烟会导致胎盘绒毛间隙血流急剧减少。这种变化在15分钟内恢复正常。在绒毛间隙血流降低时，心率和血压升高，并在整个研究期间一直保持升高状态。绒毛间隙血流的反复减少可以解释吸烟女性胎儿生长受限和一些其他妊娠并发症的原因。
