George Carson, one of the investigators on the Early External Cephalic Version
2 (ECV2) Trial.
Patients received analgesic intervention and terbutaline timed to provide peak analgesic and uterine relaxant effect at the time of external cephalic version
, said Dr.
No practitioner would think of attempting amniocentesis, external cephalic version
, cesarean section, forceps-assisted delivery, or vacuum-assisted delivery without first discussing this with the patient; however, cutting a woman's genitalia, usually unnecessarily, is thought to be in the realm of practitioner discretion," said Dr.
Chances are slim that a morbidly obese woman with a breech presentation will have a vaginal delivery, even if external cephalic version
is successful, investigators reported at the annual meeting of the Society of Obstetricians and Gynaecologists of Canada.
PARIS -- Estimated fetal weight is directly related to the success of external cephalic version
UCSF policy is to offer two attempts at external cephalic version
to women with singletons in breech presentation with an estimated fetal weight of 3,850 g or less on ultrasound, excluding women with major fetal anomalies, intrauterine fetal demise, or preexisting maternal morbidity.
SAN FRANCISCO -- A higher amniotic fluid index was associated with a greater rate of successful external cephalic version
of a breech fetus in a prospective, observational study of 1,361 patients.
There are also important guidelines to keep in mind when doing an external, cephalic version
to prevent breech delivery, he said at the meeting.
Physicians who attempt external cephalic version
of a breech fetus at 34-36 weeks' gestation may have slightly more success than those who attempt it at 37-38 weeks, according to the results of the Early External Cephalic Version
A limited examination is "appropriate and desirable," according to ACOG, in the assessment of amniotic fluid volume, fetal biophysical profile testing, ultrasound-guided amniocentesis, external cephalic version
, confirmation of fetal presentation, location of the placenta in antepartum hemorrhage, and confirmation of fetal life or death.
Yet in one prospective study, nine external cephalic versions
were successful in a group of 31 women receiving nitroglycerin.
