[Is rotation in vacuum extraction possible?].

Vacuum extraction is a traction instrument and hardly suitable for accomplishing rotation. This assumption is disproved by means of two new suction cups that are being used in China. These suction cups and their use are described together with the relevant indication.

Forceps or vacuum extraction? A comparison of effects on the newborn infant.

Sixteen women delivered by forceps and 20 women delivered by vacuum extraction (VE) owing to secondary uterine inertia were compared with a control group of 11 women who gave birth spontaneously. The cord arterial pH was lower in the VE group than in the forceps and control groups. Base deficit in both arterial and venous cord blood was greater in the VE group than in the forceps group, probably owing to the longer application and extraction times in VE than in forceps delivery. The incidence of retinal hemorrhage did not differ between the forceps and VE groups. The incidence of cephalhematomata was greater among VE infants than in the forceps and control groups. All infants were examined on the 1st and 5th day by standardized neurological and behavioural examination. There were no significant differences in neurological status between the forceps and VE groups. Thus, in low extraction with no signs of fetal asphyxia, either method can be used with safety if the obstetrician is familiar with both methods of operative vaginal delivery.

A randomized comparison of vacuum extraction delivery with a rigid and a pliable cup.

OBJECTIVE: To compare the effectiveness and complications of obstetric vacuum extraction with a rigid and a pliable cup, with a focus on neonatal retinal hemorrhage. METHODS: One hundred women requiring assisted delivery who met predefined criteria for vacuum extraction were randomly assigned to be delivered by the classic rigid Malmström cup or the pliable Silastic cup. RESULTS: Because of the faster induction of vacuum, delivery occurred more rapidly with the pliable cup, but the pliable cup detached significantly more often than the rigid cup. The overall failure rate was not significantly different between the cups. There were no significant differences between the groups with regard to Apgar scores, umbilical artery pH, birth canal trauma, or maternal blood loss, but scalp injury occurred less frequently with the soft than with the rigid cup. Retinal hemorrhage in the newborns showed a similar incidence of about 50%, and neonatal neurologic examination showed no significant differences between the groups. CONCLUSION: In comparison with the rigid cup, the advantage of the pliable cup is limited to a smaller incidence of neonatal scalp injury.

The use of the vacuum extractor in a Nigerian hospital.

The use of the vacuum extractor over a 5-year period is reviewed. The instrument was used on 319 occasions, with a 2.8% failure rate and a 25 per thousand corrected perinatal mortality. The maternal morbidity attributable to the use of the instrument was low. The main indications for use were to expedite labor either in the first or second stage because of maternal or fetal distress, and in the rotation and subsequent delivery of the malpositioned vertex. It was found to be particularly useful for the platypellic pelvis with an android tendency, a type rather common in Nigerian parturients.

Kielland's forceps or ventouse--a comparison.

A retrospective study over a 3-year period compared maternal and neonatal outcomes after birth by Kielland's forceps with those by ventouse when there was deep transverse arrest of head. Of the 259 women, 117 were delivered with Kielland's forceps and 142 were delivered with the ventouse. Of the Kielland's forceps deliveries, 15% were performed by a specialist, compared with 41% of the vacuum extractions. There were no differences in maternal morbidity overall, but when groups of operators were compared maternal complications were more frequent in the forceps group with the less experienced operators. There was little early neonatal morbidity (as judged by Apgar score, intubation, admission to the special care baby unit, jaundice and abnormal neurological behaviour) but cephalhaematoma occurred significantly more often in babies born by the ventouse than by Kielland's forceps. There were no perinatal deaths.
