Acute epidural hematoma related to cesarean section in a neonate with Chiari II malformation.

We present a rare case of acute epidural hematoma in a newborn infant with congenital hydrocephalus that was related to Chiari II malformation. The hematoma was attributed to the application of excessive suction with a vacuum extractor during cesarean section. The clinical characteristics of neonatal epidural hematoma were analyzed after a review of 18 cases in the literature, and diagnosis and treatment are discussed with reference to the results. We propose that careful follow-up is essential in neonates with cephalohematoma, and that a computed tomography (CT) study should be performed immediately if an infant's head circumference is discovered to be enlarging or if the anterior fontanel bulges.

The influence of vacuum extractor on fetal oxygenation and newborn status.

AIM: The aim of this study was to determine the effects of vacuum extractor assisted delivery on fetal oxygenation and acid-base balance. METHODS: Sixty-one women were enrolled in the present study. The subjects were divided into two groups. Group A, consisting of 39 women, had normal vaginal deliveries. Group B, consisting of 22 women, underwent a vacuum extractor assisted vaginal delivery. Fetal arterial oxygen saturation (SpO2) monitoring was used in all women after full cervical dilatation. After delivery, umbilical artery pH, pCO2, pO2 and base deficit (BDecf) levels were determined in all neonates. RESULTS: The mean FSpO2 value in Group A was 51.53+/-5.87% and in Group B 48.03+/-6.39% (p<0.03). The mean cord pH value in fetuses of Group A was 7.26+/-0.05, and in Group B 7.17+/-0.09. There was also a significant difference between the two groups with regards to mean pO2, pCO2 and BDecf values. CONCLUSIONS: Vacuum assisted vaginal delivery was associated with lower fetal arterial oxygen saturation levels as well as lower cord blood pH values compared to those seen after unassisted vaginal delivery. Although decreased, however, the above parameters remained within normal ranges.

The problem of relating fetal outcome with breech presentation to mode of delivery.

We retrospectively analyzed 546 consecutive singleton pregnancies with breech presentations that ended at > or = 36 weeks of gestation for the relationship between the intended mode of delivery and fetal outcome. Twelve patients were excluded from the analysis because these infants had major malformations. Of the 534 remaining patients, 124 (23%) were delivered by elective cesarean section. The other 410 women (77%) went into spontaneous labor. Intrapartum emergency cesarean section was required in 112 (27%) of these 410 women; the other 298 (73%) were delivered vaginally. There were 5 poor neonatal outcomes: 3 perinatal deaths and 2 cases of cerebral palsy probably due to intrapartum asphyxia. The risk of poor outcome was thus 1.2% (5/410), in the intended vaginal delivery group vs. no such outcome in the group of 124 patients that had an elective cesarean section. Three of 5 infants with poor outcome were actually born by emergency cesarean section and comparisons of results according to ultimate method of delivery rather than according to intended method of delivery may be misleading and in our case would have been biased against cesarean section.

Onset of vacuum-related complaints in neonates.

Since vacuum-related neonatal morbidity has been described in many studies clinical observation of neonates is common practice after vacuum-assisted vaginal delivery. However, no guidelines are available regarding the required length of hospital stay of these infants, because little is known about the first onset of complaints due to vacuum extraction-related morbidity. In a prospective observational cohort study we found that vacuum extraction-related complaints occurred in term neonates within 10 h following birth. Mild to moderate morbidity was frequently seen, whereas severe morbidity was infrequently seen. Previous artificial delivery, Apgar score lower than 7 at 1 min, and birth weight >4.0 kg were risk factors for morbidity after vacuum extraction. We suggest that it is justified to discharge neonates at least 10 h after vacuum delivery when no vacuum extraction-related complaints have occurred.

Clinical effects of orally administered extracts of Montanoa tomentosa in early human pregnancy.

Freshly prepared aqueous decocts of the Mexican plant Montanoa tomentosa (Zoapatle) were administered orally to six women in the early stages of pregnancy for two days prior to the interruption of gestation by vacuum aspiration. The daily dose administered varied between 1.0 and 1.4 gm-equivalent of dry leaves per kilogram of body weight. A comparable control group of six pregnant women received the same volume of commercial tea according to the same schedule before vacuum aspiration. Administration of Zoapatle extracts resulted in a menstrual-like cramp and a significant dilatation of the cervix in all subjects studied. In four of the six subjects the menstrual-like pains were associated with bleeding. No comparable effects were observed in the control group. Peroral administration of Zoapatle decocts did not produce any cardiovascular changes, and it did not influence the hematologic status, liver, kidney, and thyroid function, blood lipids, proteins, and electrolyte status. Under the experimental conditions used, Zoapatle extracts did not induce a luteolytic effect judged from the plasma progesterone (and estradiol) levels. It is concluded that peroral administration of freshly prepared decocts of Zoapatle in early pregnancy exerts a distinct uterotonic effect and induces cervical dilatation and uterine bleeding. These changes are not associated with any effect on the plasma levels of progesterone and estradiol or with any untoward side effects.

Factors related to the increasing cesarean section rates for cephalopelvic disproportion.

At the Highland Park Hospital the increase in cesarean section rates has paralleled the national increase. Data from cesarean deliveries performed for cephalopelvic disproportion (a leading reason for cesarean section) in 1969 to 1972 (group 1) and 1979 to 1982 (group 2) were evaluated to determine maternal, fetal, and delivery factors that might be related to the increase in the rates. The data suggested that the more frequent diagnosis of cephalopelvic disproportion and the increased size of the group 2 infants were the primary reasons for the increase in cesarean section rate. This increased rate was paralleled by a decline in forceps-assisted delivery and in perinatal mortality rates.
