对胎儿、胎盘和子宫肌层的氧合威胁
This book presents the theory that positional obstruction of the inferior vena cava by the gravid uterus might contribute to the causation of preeclampsia, fetal growth restriction, preterm birth, dysfunctional labor and uterine atony. Investigating this possibility is timely, since non-invasive technology now exists which detects hemodynamically significant obstruction of the inferior vena cava in real time, by relying on the fact that such obstruction causes an immediate decrease in maternal cardiac output. If further research shows that obstruction of uterine venous return at the inferior vena cava can cause maternal or fetal injury, systematic reduction of this obstruction during gestation might improve maternal and fetal outcomes.
Written in a direct, informal and engaging style-- and enriched with clinical insights and abundant colorful graphics-- this thought-provoking and potentially ground-breaking work should be of interest to maternal and neonatal health professionals, including obstetricians, maternal-fetal medicine specialists, neonatologists, obstetric anesthesiologists and midwives.
这本书提出了一个理论:胎盘增大可能通过阻塞下腔静脉来导致先兆子痫、胎儿生长受限、早产、不协调性宫缩和子宫无力。研究这一可能性是适时的,因为目前存在一种非侵入性技术可以在实时中检测到下腔静脉显著血流动力学阻塞的情况,该技术依赖于这样的事实:这种阻塞会导致母体心输出量立即下降。如果进一步的研究表明下腔静脉阻塞子宫回流可以导致母体或胎儿的损伤,那么在妊娠期间系统减少这种阻塞可能会改善母体和胎儿的结果。 这篇文章写作风格直接、轻松且引人入胜——并结合了丰富的临床见解和大量的彩色插图——这本激发思考且可能开创先河的作品应该对包括妇产科医生、产科学专家、新生儿医学家、妇产科麻醉师和助产士在内的母婴健康专业人士具有吸引力。
