１３１４０次分娩中持续性枕后（横）位８４８例，发生率为６５％。随着胎儿体重的增加，持续性枕后（横）位的发生率明显增加，≥３５００ｇ胎儿的发生率高达９６％，剖宫产率为８９１％。胎儿体重≥３０００ｇ，＜４０００ｇ者产钳助产率最高（１６８％）。胎儿体重≥２５００ｇ，＜３０００ｇ者胎吸助产率最高（１８７％）。体重＜２５００ｇ者阴道自然分娩率为７０４％；体重≥２５００ｇ，＜３０００ｇ者阴道自然分娩率明显降低（Ｐ＜００１）。持续性枕后（横）位的新生儿窒息率为１４２％，以≥３０００ｇ，＜４０００ｇ者最高（１６６％）。胎儿体重≥３５００ｇ者产后出血率高达９０％。建议：在持续性枕后（横）位的诊断与处理中应充分考虑到胎儿的体重因素，以减少母儿并发症 Of the 13,040 deliveries, there were 848 cases of persistent occipital (horizontal) position, the incidence was 65%. With the increase of fetal weight, the incidence of persistent occiput (transverse) significantly increased, the incidence of ≥ 3500g fetus was as high as 9.6%, and the rate of cesarean section was 89.1%. Fetal weight ≥ 3000g, <4000g forceps the highest yield (16.8%). Fetal weight ≥ 2500g, <3000g fetus assists the highest yield (18  7%). The natural delivery rate of vagina of body weight <2500g was 704%. The natural vaginal delivery rate of body weight≥2500g, <3000g was significantly decreased (P <001). The rate of neonatal asphyxia was 142% in persistent occipital (transverse) position, and was highest in ≥3000g, <4000g (166%). Fetal weight ≥ 3500g postpartum hemorrhage rate as high as 9  0%. Recommendation: In the continuous diagnosis of occiput (transverse) position and treatment should take full account of fetal weight to reduce maternal and child complications
