Approximately 50% of twin pregnancies deliver preterm, and major complications associated with prematurity include respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage, and sepsis. These complications drive the perinatal mortality rate of twins to seven times that of singletons. Although delivery may take place due to iatrogenic or spontaneous etiologies-no matter what the indication-optimizing the route of delivery for twins is an important component of care that must be thoughtfully considered.
约50%的双胎妊娠会早产,与早产相关的主要并发症包括呼吸窘迫综合征、坏死性小肠结肠炎、脑室内出血和败血症。这些并发症使双胎围产期死亡率达到单胎的7倍。尽管分娩可能因医源性或自发原因而发生——无论指征如何——优化双胎的分娩途径是必须慎重考虑的重要护理内容。
