Vacuum-assisted delivery: an analysis of traction force and maternal and neonatal outcomes.

Safety recommendations for vacuum-assisted delivery focus on limiting the number of pulls and the duration of the procedure. With the introduction of the Kiwi OmniCup vacuum extractor incorporating a Traction Force Indicator, it is now possible to reliably monitor and control the amount of traction force exerted on the fetal scalp. The OmniCup was used in a prospective observational study of 119 vacuum-assisted deliveries in nulliparous women to establish practical guidelines for safe practice in typical clinical settings.

Vacuum-assisted delivery.

Unsuccessful vacuum extraction, cup detachment and failed anterior rotation in occipitoposterior positions are commonly associated with obstetric factors that are avoidable or correctable. These factors include the preferential use of soft vacuum cups, incorrect cup applications and attempts to deliver with the vacuum extractor before the cervix is completely dilated. Evidence from randomized trials demonstrates that soft cups cause fewer cosmetic effects and scalp lacerations than rigid cups. Soft cups do not reduce the incidence of cephalhaematomas nor have they been shown to provide any advantage over rigid cups for the prevention of subgaleal haemorrhage. Clinically significant subgaleal haemorrhage and intracranial injury are almost always preceded by difficult vacuum extraction. Although the vacuum extractor is less likely than forceps to injure the mother's genital tract and anal sphincters at delivery, no significant differences have been demonstrated between the instruments in terms of subsequent urinary or bowel disturbances.

The 'sacral hand wedge': a cause of arrest of descent of the fetal head during vacuum assisted delivery.

During a study of 108 vacuum assisted deliveries, a fetal hand was detected in the pelvic space between the head and maternal sacrum in seven of the procedures. The larger presenting diameters resulting from the compound fetal presentations were reflected in a greater number of pulls and higher traction forces recorded during the deliveries. In all cases, extraction of the hand facilitated the completion of birth without causing serious injury to the fetus or maternal perineum. It is recommended that a digital examination to detect the presence of a fetal hand in the sacral space should become a part of standard vacuum delivery practice.
