| pubmed-article:842306 | pubmed:abstractText | During 1969--1974 six hundred and forty-nine external versions were attempted during the last trimester on 491 mothers with fetal malpresentation. The procedure was monitored with ultrasound in 1969--1974. Most of attempts (70.0%) were made during the 32nd-36th weeks. The final version rate after one or more attempt was 76.2%, being lower (67.0%) in nulliparous than parous women (84.6%). The incidence of breech presentation at birth decreased from 4.5 to 2.9% (p less than 0.001). The most serious complication was one premature labor but the infant survived. The perinatal mortality was 2.0% and, after excluding abnormal infants, 0.8%. The combination of external version and the use of ultrasound is a safe method which avoids hazardous vaginal breech delivery and is recommended in obstetric practice. | lld:pubmed |
