trial forceps

trial forceps

Etymology: Fr, trier, to sort out
an obstetric operation consisting of an attempt to deliver an infant with obstetric forceps. The forceps are applied to the baby's head, and moderate traction is applied. The delivery is continued only if the trial indicates that delivery can be accomplished safely. The procedure is abandoned if proper application of the forceps or rotation of the baby's head is not possible or if the trial indicates that completion of the delivery with forceps will require inordinately heavy traction likely to be more traumatic to the mother or baby than cesarean section. Trial forceps is usually performed with a double setup so that cesarean section can be carried out immediately if necessary. Compare failed forceps. See also double setup.
