Seventy frank breech fetuses delivered vaginally, alive at the onset of labor, and without major congenital anomalies were matched by birth weight and race with a breech infant born by cesarean section, a vertex infant born vaginally, and a vertex infant born by cesarean section. Long-term neurological abnormality was determined from time of hospital discharge through a minimum of 2 years of age. The results document the absence of significant differences with respect to major brain damage effected by birth route changes for breech fetuses and between the entire breech and vertex populations.
七十例在分娩开始时存活且无重大先天性异常的足先露胎儿经阴道分娩，将其按出生体重和种族与剖宫产出生的臀位婴儿、经阴道出生的头位婴儿以及剖宫产出生的头位婴儿进行匹配。从出院时起至至少两岁，确定长期神经异常情况。结果表明，足先露胎儿因分娩方式改变而导致的重大脑损伤，以及整个臀位和头位人群之间，均不存在显著差异。
