[Collection of obstetric-perinatologic outcome data in the Frankfurt (Oder) district].

To assess health-care and quality in perinatal care a questionnaire was sent to all of the gynaecologic departments in the district of Frankfurt (Oder), GDR, asking details about prenatal care examination, fetal monitoring and perinatal mortality. The results of this pilot study indicate a high level in quality of health care in that region (perinatal mortality in 1985: 7.5%). Our findings suggest that quality-control and quality-comparisons are measures to ameliorate health, care organization, too. The reasons for the change in perinatal mortality will be analyzed in further investigations.

Cesarean section and perinatal mortality in Sweden in 1981.

During the years 1973-81, the cesarean section (CS) birth rate increased from 5.5% to 12.4% in Sweden. During the same time, perinatal mortality declined from 12 to 7.1 per thousand children. The rates of CS and perinatal mortality, however, cannot be presented as reciprocally dependent variables without taking into consideration many of the other factors that have been at work during the same decade, e.g. improved results of the neonatologists in the lower weight groups, electronic fetal monitoring, use of steroids, introduction of tocolytic agents. The present study revealed that the incidence of CS could vary between 8% and 19% between different obstetric departments in Sweden during 1981. Despite this great difference in CS rate, no difference was noted in the rates of asphyxia or perinatal mortality. It is concluded that in the present study we have seen no indication that a marked increase in the CS rate would improve our present perinatal survival data and furthermore it still remains unproven that CS and perinatal mortality rates necessarily have a reciprocal relationship.

[Obstetrical injuries of the newborn infant. Retrospective study apropos of 20,409 births].

We have been able to find 291 cases of obstetric trauma when we analysed the 20,409 deliveries which took place in the Pitié maternity between 1971 and 1980. It has been shown that bony lesions did well in the long and short term but nerve lesions had a far less good prognosis. This pathology should become far less when it is possible to recognize better when the fetus is large and when such traumatising manoeuvres as high forceps and assisted deliveries of large breech babies are stopped.

[Deciding criteria for vaginal delivery from breech presentation--effect on neonatal early and late morbidity].

In the past 20 years, breech presentation obstetrics has been characterised mainly by the work of Kubli (1975): "The safest and most simple way to prevent the foetal obstetric risk of breech presentation is the systematic Caesarean section." In the past, this resulted in judicial decisions in which due to vaginal delivery a child has been damaged and the doctor has been reproached for not performing a Caesarean section. In the report of the "Standardkommission BEL" (1983) as well as in the Guidelines for the Management of Breech Delivery (FIGO 1993), subtile criteria of decision were demanded for the vaginal delivery method. To an increasing extent clinics lack the necessary training for vaginal-operative delivery for breech presentation, followed by economic obligations and, as a result, in 1994 the frequency of Caesarean sections in cases of breech presentation was 86.9% in Bavaria. Investigations should be made as to whether it is actually necessary, for the benefit of the child, to subject a mother of a breech baby to such high-risk operations. From 1988 to 1995, 1116 breech babies were born in the Gynaecological Clinic Nürnberg, Dept. of Obstetrics. The case history of 650 children with a period of gestation > 32 weeks of pregnancy were evaluated: parity, period of gestation, method of delivery, condition after Caesarean section, premature rupture of the foetal membranes, position of legs, weight of child, Apgar score, umbilical artery pH, base excess in umbilical artery mval/l, transfer ratio to paediatric clinic, reason of transfer to paediatric clinic, rate and duration of intubation, cranial sonogram and electroencephalogram.

An Australian prospective cohort study of risk factors for severe perineal trauma during childbirth.

OBJECTIVE: to determine risk factors for the occurrence of severe perineal trauma (third and fourth degree tears) during childbirth. DESIGN: a prospective cohort study was conducted using the hospital's computerised obstetric information system. Additional data were gathered on women who sustained severe perineal trauma. Descriptive statistics and logistic regression were used to assess risk factors for severe perineal trauma. Midwives were asked to comment on possible reasons for severe perineal trauma. Written responses made by midwives were analysed using content analysis. Discussion groups with midwives were held to further explore their experiences. SETTING: Royal Prince Alfred Hospital, Sydney, Australia. PARTICIPANTS: all women having vaginal births (n=6595) in a 2-year period between 1 April 1998 and 31 March 2000, in both the birth centre and the labour ward. MEASUREMENTS AND FINDINGS: 2% of women (n=134) experienced severe perineal trauma. One hundred and twenty-two women had third-degree tears and 12 had fourth-degree tears. Primiparity, instrumental delivery, Asian ethnicity and heavier babies were associated with an elevated risk of severe perineal trauma. Midwives identified several factors they believed contributed to severe perineal trauma. These were lack of effective communication with the woman during the birth, different birth positions, delivery technique, ethnicity and obstetric influences. KEY CONCLUSIONS: findings support current knowledge that primiparity, instrumental birth, heavier babies and being of Asian ethnicity are associated with increased rates of severe trauma. Specific attention needs to be paid to the strong association found between being of Asian ethnicity and experiencing severe perineal trauma. IMPLICATIONS FOR PRACTICE: further identification and validation of the concerns expressed by midwives to reduce severe perineal trauma is warranted so that preventative strategies can be used and researched.

Face presentation in modern obstetrics--a study with special reference to fetal long term morbidity.

Thirty-one cases of face presentation were analyzed with regard to obstetric management and long-term outcome. Vaginal delivery occurred in 14 of 15 mentum anterior face presentations whereas only one of 16 patients with a mentum transverse of mentum posterior face presentation were delivered vaginally. Face presentation was associated with an increased incidence of variable decelerations. At follow-up (2-12 years) one infant had a neurological sequelae which could be associated to the delivery in face presentation. The implication of these findings for the management of face presentations is discussed.

Prioritizing posterior arm delivery during severe shoulder dystocia.

BACKGROUND: Delivery of the posterior arm, or the Barnum maneuver, is at times used late in shoulder dystocia management algorithms, and is not often a first- or second-line management protocol. CASE: A multiparous, diabetic patient, who was morbidly obese and had a residual obstetric brachial plexus injury, experienced a precipitous second stage of labor and severe shoulder dystocia. Attempts at the McRoberts maneuver with traction failed to deliver the fetus. In lieu of alternative maneuvers or continued attempts at traction, the posterior arm was delivered and the fetal trunk followed easily. CONCLUSION: A geometric analysis reveals that using posterior arm delivery reduces the obstruction by more than a factor of two, relative to the McRoberts maneuver. We recommend earlier use of this maneuver during shoulder dystocia management.

Elective induction of labour in the obstetrical practice.

Maternal and foetal results of 2020 elective inductions of labour are presented, compared with those of 2750 pregnancies in which labour was not induced during the 40th week of gestation, awaiting for its spontaneous onset. The morbidity, mortality, and the frequency of obstetric operations during labour were compared. In all the parameters compared, there were better results in the electively induced group. The author attributed this difference to the establishment of careful selection criteria for elective induction. These criteria are: reliable estimate of gestational age, mature foetus over 3000 g of body weight, ripe cervix, proven myometrial sensitivity to oxytocin. Following these rules, the elective induction of labour can be a valuable and safe method of prevention of maternal and foetal complications.

Nerve injuries in neonates.

A clinical study of 40 cases of nerve injuries in neonates with one-year follow-up is presented. The total incidence of such injuries was 1.50%. Thirty-three cases sustained nerve injury due to obstetrical trauma and in 7 cases it was due to postnatal trauma like intragluteal injection and tight splintage. Almost in all cases there was history of prolonged or obstructed labour. Upper limb nerve injuries were commonest followed by facial palsy. Twenty-three cases (76%) showed complete recovery while 17% had partial and 7% no recovery at all. Hence nerve injuries are not uncommon in neonates. If managed properly the recovery is good. Intragluteal injection in the neonatal period should not be recommended.

Brachial plexus injuries and shoulder dystocia: medico-legal commentary and implications.

Brachial plexus injuries may occur in association with or without recognised shoulder dystocia. Until recently many medico-legal experts argued that these injuries resulted from the negligent use of excessive or misdirected traction. These experts did not accept that the natural forces of labour could cause the injury. In cases of recognised shoulder dystocia, modern obstetric practice has recognised the importance of correct maternal positioning and the need to avoid excessive or misdirected traction, also the importance of not applying a rotational force to the fetal head. Informed practice and the increased use of caesarean section has not reduced the number of brachial plexus injuries. Judges in two recent trials found that the natural forces of labour were the cause of the injury and that the birth assistants had not caused the damage. This has important implications for medical note writing, teachers and risk managers, medico-legal experts and lawyers.

Rupture of the larynx in a newborn.

BACKGROUND: Lesions of the laryngotrachea due to repeated intubation trauma after birth are reported. CASE: A macrosomic neonate was born at term after uneventful pregnancy. On the basis of diminished uterine contractions and arrest of descent, the head was delivered by using obstetric forceps. No intubation was attempted after birth. Ten hours later, the infant developed acute life-threatening respiratory distress and subcutaneous emphysema. Intubation was impossible. Open surgical exploration of the neck revealed a rupture of the cricothyroid ligament within the larynx. The defect was closed immediately, and after artificial ventilation for 7 days, the infant was extubated. One year later, the child is developing satisfactorily, without stridor or hoarseness. CONCLUSION: In macrosomic neonates after traumatic delivery, a laryngotracheal lesion should be considered when respiratory distress syndrome combined with subcutaneous emphysema occurs.

Vacuum assisted delivery--the need for caution.

In the United Kingdom and Republic of Ireland 10% of all deliveries are vacuum assisted. The vacuum is preferred over forceps because it is easier to perform and associated with less maternal morbidity. It is, however, also associated with subaponeurotic haemorrhage that has an incidence of 6.4 per 1000 vacuum assisted deliveries and a mortality of 23%. Based on a figure of 77,500 births annually in Ireland, North and South, it is possible that as many as 11 neonatal deaths each year may attributable to what is generally considered a safe obstetric intervention. In North America concerns about the safety of vacuum assisted delivery resulted in the issuing of public health advisories in both Canada and the United States. To date such concerns have not been raised in either the United Kingdom or Republic of Ireland. We report a case of fatal subaponeurotic haemorrhage to highlight and bring these concerns to the attention of obstetricians, paediatricians and midwives. We also call for the introduction of a national surveillance in order to assess the true extent of this potentially fatal complication.

[Maternal paralysis of obstetrical origin. Two case reports].

We report two cases of maternal obstetrical paralysis by injuries to the sacral plexus (lumbosacral trunk). This nervous lesion is rare and occurs more often in young small primigravidae, carrying a large fetus, during a prolonged labor and a delivery requiring midforceps. The symptoms appear usually a few hours after delivery: paresthesias of the leg and the foot as well as weakness and possible footdrop (the paralysis may be mild or severe). The different mechanisms involved are inspected. The prognosis of this lesion is good, the patients recover usually within a period of three months. The treatment appears to be physiotherapy.

Is permanent congenital facial palsy caused by birth trauma?

OBJECTIVE: To study the relation between traumatic birth and the development of permanent facial palsy in the newborn. DESIGN: Retrospective case control study of children with 'congenital' facial palsy. SETTING: Two tertiary referral centres for patients with facial palsy. SUBJECTS: 61 children with established facial palsy. MAIN OUTCOME MEASURES: Odds ratios of recognised factors for birth injury: maternal primiparity, high birth weight, and the use of obstetric forceps at delivery. RESULTS: 13.2% of those studied had forceps assisted delivery compared to 10.2% in the normal population (odds ratio 1.34; 95% confidence intervals 0.61 to 2.97) 39.6% were born to primiparae compared to a national rate of 36.7% (1.13; 0.65 to 1.96) and only 18.9% weighed more than 3500 g at birth (0.37; 0.19 to 0.74). CONCLUSIONS: There is no association between the development of permanent 'congenital' facial palsy and recognised risk factors for birth injury. These data suggest an intrauterine rather than a traumatic aetiology.

Macrosomic babies.

A review of 3,241 delivery records was made to study the obstetrics and the neonatal outcomes of 129 macrosomic (greater than or equal to 4,000g) babies. They were found to have a nearly 6-fold increase in the neonatal morbidity rate compared with normosomic babies. The emergency Caesarean section rate for nulliparas and parous women with macrosomic babies was 41.3% and 8.4% respectively. Among macrosomic babies, shoulder dystocia was not associated with maternal stature, induction of labour, use of oxytocin or abnormal labour patterns, but was associated with instrumental delivery. Macrosomic babies with shoulder dystocia after instrumental delivery had a higher neonatal morbidity rate than those delivered spontaneously.

Differences in umbilical venous and arterial leptin levels by mode of delivery.

OBJECTIVE: To investigate the differences in umbilical venous and arterial leptin levels by mode of delivery. METHODS: Subjects were 30 mothers who had elective cesarean deliveries and 34 mothers who had vaginal deliveries. Umbilical venous and arterial leptin levels were measured immediately after delivery. Maternal age, neonatal gender, neonatal birth weight, placental weight, and gestational duration were recorded. Inter- and intragroup comparisons were made in umbilical venous and arterial leptin levels and obstetric variables. Significant determinants of differences in umbilical venous and arterial leptin levels were investigated. RESULTS: Umbilical venous and arterial leptin levels were higher in the vaginal delivery group (n = 34) than in the cesarean group (n = 30) (P <.01). In the vaginal delivery group, umbilical venous leptin levels were significantly higher than arterial leptin levels (P <.001). These differences were still significant after adjustment for neonatal gender, neonatal birth weight, and placental weight. However, in the cesarean group, leptin levels did not differ between umbilical vein and artery. CONCLUSION: Placental leptin release is augumented during advanced labor.

Obstetric practice and infant morbidity.

A method is described of using matched pairs of index infants and controls to examine the hypothesis that induction or some other obstetric practice is associated with increased morbidity in the mature infant. All infants over 2250 g and 37 weeks gestation, without severe congenital defect or history of severe maternal disorder, born in the John Radcliffe and admitted to the Special Care Baby Unit in 1975 were identified. For each of these index infants a matched control was chosen using strict criteria. Contrast between the 109 matched pairs showed no significant differences between maternal characteristics, induction of labour, use of forceps or duration of labour. There was an excess of index infants born to mothers who had had epidural anaesthesia (P less than 0.05).

What factors are associated with neonatal injury following shoulder dystocia?

OBJECTIVE: To identify factors associated with the development of neonatal injury in the setting of shoulder dystocia. STUDY DESIGN: Medical record ICD-9 codes and a computerized perinatal database were reviewed to identify cases of shoulder dystocia from January 1996 to January 2001 in a tertiary care center. For confirmation of the diagnosis and collection of data, both maternal and neonatal charts were then reviewed and neonatal injuries categorized as either neurological (brachial plexus injury) or skeletal (clavicular fracture, humeral fracture). Shoulder dystocia cases were divided into groups based on the presence of neonatal injury at delivery or at discharge (with or without Erb's palsy). The group with neonatal injury was compared for demographic and obstetrical factors to the group without injury (control). chi (2) test, Mann-Whitney test and logistic regression were used as appropriate. RESULTS: During this 5-year period, there were 25,995 deliveries and 206 (0.8%) confirmed cases of shoulder dystocia. Of these cases, 36 (17.5%) had neonatal injury diagnosed at delivery and 25 (12%) remained with significant residual injury at discharge. Of these there were 19 cases of Erb's palsy and six cases of clavicular fracture. No association was found between neonatal injury and maternal age, ethnicity, diabetes, operative vaginal delivery or number of obstetrical maneuvers. However, maternal body mass index >30 kg/m2, a second stage of labor >20 min and a birth weight >4500 g were all associated with an increased risk of neonatal injury at delivery and at discharge, including Erb's palsy. After logistic regression analysis, only a second stage of delivery >20 min remained significantly associated with neonatal injury at discharge. CONCLUSION: In our population, maternal obesity was associated with an increased risk of neonatal injury after shoulder dystocia. In addition, a short second stage of labor (<20 min) was associated with a lower rate of neonatal injury.
