To determine ultrasonic estimations of amniotic fluid in diamniotic twins across gestation using the single deepest pocket (SDP) technique and correlate volumes to intrapartum and neonatal outcomes.
Prospective observational study using diamniotic dichorionic and diamniotic monochorionic pregnancies. Intrapartum and neonatal outcomes were evaluated.
Between April 2004 and April 2006, 299 women were recruited. There was no significant relationship between SDP and gestational age. Statistically significant differences by SDP groups (for low, normal, and high volumes) include preterm delivery (P = .043; 56, 62, and 86%), abnormal labor tracing (P = .013; 5, 8, and 27%), fetal labor intolerance (P = .026; 6, 9, and 27%), Apgar scores at 5 minutes (P = .028; 17, 10, and 27%) and any neonatal complications (P = .002; 28, 21, and 55%).
The SDP is constant between 17 and 37 weeks. Fetal labor intolerance and adverse neonatal outcomes are greater in a twin with hydramnios.
采用单一最深羊水池（SDP）技术确定双羊膜囊双胎妊娠全孕期羊水的超声评估值，并将羊水量与产时及新生儿结局相关联。
对双羊膜囊双绒毛膜和双羊膜囊单绒毛膜妊娠进行前瞻性观察研究。评估产时及新生儿结局。
2004年4月至2006年4月期间，招募了299名女性。SDP与孕周之间无显著关系。SDP分组（低、正常和高羊水量）在统计学上的显著差异包括早产（P = 0.043；56%、62%和86%）、产程异常（P = 0.013；5%、8%和27%）、胎儿产程不耐受（P = 0.026；6%、9%和27%）、5分钟时的阿氏评分（P = 0.028；17%、10%和27%）以及任何新生儿并发症（P = 0.002；28%、21%和55%）。
SDP在17至37周之间保持恒定。羊水过多的双胎胎儿产程不耐受及不良新生儿结局的发生率更高。
