目的　探讨双胎儿针对性保健措施。方法　调查在本院分娩的 36 3对双胎儿及 3745 6例单胎儿围产期 (Ⅲ )状况 ,随访胎儿远期预后。结果　①双胎儿早产、低出生体重、胎位不正、难产、胎儿窘迫、胎盘异常、胎膜早破、羊水粪染的发生率及患病率、围产期病死率显著高于单胎儿 ;双胎孕母 >30岁、经产妇、体力劳动者的比例及孕期并发症的发生率显著高于单胎。②单卵双胎儿的羊水粪染、早产的发生率及患病率、围产期病死率显著高于双卵双胎儿 ,小双 (双胎儿按出生先后分为大、小双 )的羊水粪染、难产、出生时窒息的发生率显著高于大双。③双胎儿 4～ 9岁时的体重、头围显著低于单胎儿 ,低智儿比例显著高于单胎儿。结论　双胎儿围产期状况及近、远期预后均较单胎儿差 ,其中单卵双胎儿、小双尤著 ,应加强相应的保健措施 Objective To investigate the twin fetuses targeted health care measures. Methods A total of 363 pairs of twins and 37456 cases of single fetuses (Ⅲ) during delivery in our hospital were investigated. The prognosis of the fetus was followed up. Results ① The incidence and prevalence of preterm birth, low birth weight, abnormal fetal position, dystocia, fetal distress, abnormal placenta, premature rupture of membranes, meconium-stained amniotic fluid, and perinatal mortality were significantly higher in twin fetuses. Twins Pregnant mother> 30 years old, the proportion of mothers, manual workers and pregnancy complications was significantly higher than the single birth. ② monozygotic twins of amniotic fluid dyed, the incidence and prevalence of preterm birth, perinatal mortality was significantly higher than the double egg double fetus, small double (according to the birth of twins have been divided into large and small double) amniotic fluid excrement Dye, dystocia, the incidence of asphyxia at birth was significantly higher than the double. ③ twin 4 to 9 years old, body weight, head circumference was significantly lower than the single fetus, low Chi child was significantly higher than the single fetus. Conclusions The perinatal status and the short-term and long-term prognosis of twin fetuses are worse than those of single fetuses. Among them, single fetus and twin fetuses are younger and younger, and corresponding health care measures should be strengthened
