Obstetric prognosis after placental abruption.

OBJECTIVE: To assess obstetric outcome in women with a history of placental abruption. METHODS: We utilised the population-based birth registry data of Kuopio University Hospital to investigate pregnancy outcome in 59 women with prior placental abruption. The general obstetric population was used as a reference group in logistic regression analysis. RESULTS: Recurrent placental abruption and associated adverse neonatal outcome occurred in 11.9% (7:59) of the women. If the disease did not recur, a history of placental abruption had no significant effects on birth weight, fetal distress or prematurity rate, whereas the incidence of pre-eclampsia was found to be increased. CONCLUSIONS: Women in whom placental abruption does not recur have a good outcome in their subsequent delivery, almost comparable to that in the general obstetric population. However, the recurrence rate of 11.9% is high (OR: 16.9, 95% CI: 8.2-34.9) when compared with the background incidence of placental abruption (0.7%).

[Significance and limitations of obstetrical ultrasound].

Obstetrical ultrasound is practised in Germany, Austria and Switzerland as a screening examination for all pregnancies. Although the reasons for its introduction in Germany in 1981 were dating of pregnancy, detection for multiple pregnancies and detection of intrauterine growth retardation, its aims has shifted towards the detection of fetal malformations when the 3-point obstetrical screening was introduced in 1995. To produce a realistic quality for this large number of examiners, a multi-level system was introduced. Today, contents and quality requirements of the 3 screening examinations (at 10/20/30 weeks), the 3 levels of examination and of the ultrasound equipment can be defined. This should help optimize the still insufficient quality of obstetrical ultrasound and reduce unrealistic expectations.

Cervicothoracic extradural arachnoid cyst: possible association with obstetric brachial plexus palsy.

The association of cervicothoracic extradural arachnoid cysts and obstetric brachial plexus palsy has not previously been reported. We report two patients with this association. The first patient is a 9-month-old boy with left obstetric brachial plexus palsy that developed bilateral leg weakness at 6 months of age owing to compression of the spinal cord by a C6 to T8 left cervicothoracic extradural arachnoid cyst. The second patient is a 3-year-old girl with bilateral brachial plexus palsy and spastic paraparesis who had magnetic resonance imaging at 3 days of age that showed intraspinal cord injury and a cervicothoracic extradural arachnoid cyst compressing the spinal cord. We believe that the association of cervicothoracic epidural arachnoid cysts and obstetric brachial plexus palsy in these patients was causal and recommend that the possibility of a cervicothoracic epidural arachnoid cyst be considered in patients with brachial plexus palsy and evidence of spinal cord injury.

Limited obstetric ultrasound examinations: competency and cost.

OBJECTIVE: To determine both the actual dollar cost and the amount of time required per nurse to establish competency in limited obstetric ultrasonography (LOBU). DESIGN: Descriptive. SETTING: A tertiary care setting. PARTICIPANTS: Registered nurses who were taught in LOBU. RESULTS: Nurses who attained competency in LOBU completed 12 hours of didactic education and a clinical practicum consisting of 6 to 9 hours and approximating 15 ultrasound scans. For five nurses to concurrently attain competency in LOBU, the cost per nurse was $1,037.55 (includes salaries and employee benefits). CONCLUSION: Registered nurses are able to acquire competency in LOBU at a reasonable cost, thus enhancing the ability of the professional nurse to deliver a fuller scope of services in an obstetric setting. For institutions that have limited access to individuals with this skill, nurses trained in LOBU may present a high-quality, cost-efficient solution to providing needed obstetric services.

Obstetric prognosis in sisters of preeclamptic women - implications for genetic linkage studies.

BACKGROUND: To investigate obstetric prognosis in sisters of preeclamptic women. METHODS: We identified consecutive 635 sib pairs from the Birth Registry data of Kuopio University Hospital who had their first delivery between January 1989 and December 1999 in our institution. Of these, in 530 pairs both sisters had non-preeclamptic pregnancies (the reference group), in 63 pairs one of the sisters had preeclampsia and the unaffected sisters were studied (study group I). In 42 pairs both sister's first delivery was affected (study group II). Pregnancy outcome measures in these groups were compared. RESULTS: Unaffected sisters of the index patients had uncompromised fetal growth in their pregnancies, and overall, as good obstetric outcomes as in the reference group. The data on affected sisters of the index patients showed an increased prematurity rate, and increased incidences of low birth weight and small-for-gestational age infants, as expected. CONCLUSION: Unaffected sisters of the index patients had no signs of utero-placental insufficiency and they were at low risk with regard to adverse obstetric outcome, whereas affected sisters were high-risk. Clinically, affected versus unaffected status appears to be clear-cut in first-degree relatives regardless of their genetic susceptibility and unaffected sisters do not need special antepartum surveillance.

Pregnancy in patients with rheumatic diseases: obstetric management and monitoring.

The obstetric management of the pregnant rheumatic patient is largely dictated by the specific disease and the degree to which it is associated with recognizable and treatable adverse obstetric outcomes, maternal or fetal. This review will cover the obstetric management of women with systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS), rheumatoid arthritis (RA) and systemic sclerosis (SSc). Most experts agree that a co-ordinated management effort on the part of obstetricians and rheumatologists will likely yield the optimal achievable results.

Obstetric complications and risk of schizophrenia. Effect of gender, age at diagnosis and maternal history of psychosis.

BACKGROUND: Obstetric complications have been studied frequently as possible risk factors for schizophrenia. AIMS: To test the hypotheses that individual obstetric complications are most strongly associated with an increased risk of schizophrenia in males, in patients with an early age at first diagnosis and in subjects with a maternal history of psychosis. METHOD: Cases of schizophrenia diagnosed between January 1971 and June 1994 were identified in the Stockholm County In-Patient Register. Controls were matched on age, gender, hospital of birth and parish of birth. Obstetric data were recorded blind to case-control status for 524 cases and 1043 controls. RESULTS: This study did not find any large or consistent effect of gender, age at diagnosis or maternal history of psychosis on the risk of schizophrenia associated with individual complications. CONCLUSIONS: Future studies should examine these effects using a much larger sample that includes patients with schizophrenia and control subjects whose genetic risk of schizophrenia has been assessed accurately.

Transfer of pectoral nerves to the musculocutaneous nerve in obstetric upper brachial plexus palsy.

OBJECTIVE: To investigate the results of transfer of pectoral nerves to the musculocutaneous nerve for treatment of obstetric brachial palsy. METHODS: In 25 cases of obstetric brachial palsy (20 after breech deliveries), branches of the pectoral nerve plexus were transferred directly to the musculocutaneous nerve. For all patients, the nerve transfer was part of an extended brachial plexus reconstruction. Results were tested both clinically and with the Mallet scale, at a mean follow-up time of 70 months (standard deviation, 34.3 mo). RESULTS: There were two complete failures, which were attributable to disconnection of the transferred nerve endings. The results after transfer were excellent in 17 cases and fair in 5 cases. Steindler flexorplasty improved elbow flexion for three patients. CONCLUSION: Transfer of pectoral nerves to the musculocutaneous nerve for treatment of obstetric upper brachial palsy may be effective, if the specific anatomic features of the pectoral nerve plexus are sufficiently appreciated.

External rotation as a result of suprascapular nerve neurotization in obstetric brachial plexus lesions.

OBJECTIVE: Obstetric brachial plexus lesions may cause lifelong limitations of upper limb function. Nerve repair is widely advocated in infants who do not show spontaneous recovery. Typically, the suprascapular nerve (SSN) is involved in the lesion. Neurotization of the SSN routinely is performed, aiming at reinnervation of the infraspinatus muscle to restore external rotation. The results after SSN neurotization have not, as yet, been studied in detail; therefore, this study was undertaken. Of special interest was the comparison of two commonly applied SSN neurotization procedures: nerve grafting from C5 versus nerve transfer of the accessory nerve. METHODS: Infants with obstetric brachial plexus lesions after nerve grafting of C5 to the SSN (n = 65) or nerve transfer of the accessory nerve to the SSN (n = 21) were selected for retrospective analysis after a mean follow-up period of 3 years. Outcome was expressed in degrees of true glenohumeral external rotation. This was defined as the angle between the position of the 90 degrees (actively or passively) flexed elbow resting against the abdomen and the position of the flexed elbow after external rotation with the upper arm held in adduction by the investigator. This movement can be executed only by infraspinatus muscle contraction. In addition, functional external rotation was evaluated by testing the ability to reach the mouth and the back of the head. RESULTS: Only 17 (20%) of the 86 patients reached more than 20 degrees of external rotation, whereas 35 (41%) were unable to perform true external rotation. There was no statistically significant difference between nerve grafting from C5 and extraplexal nerve transfer using the accessory nerve. Functional scores showed that 88% can reach the mouth and that 75% can reach the head. CONCLUSION: The restoration of a fair range of true glenohumeral external rotation after neurotization of the SSN in infants with obstetric brachial plexus lesions, whether by grafting from C5 or by nerve transfer of the accessory nerve, is disappointingly low. However, it seems that compensatory techniques contribute to effectuate a considerable range of movement.

Obstetric complications in patients with hereditary thrombophilia identified using the LCx microparticle enzyme immunoassay: a controlled study of 5,000 patients.

Factor V Leiden (FVL) and prothrombin (PT) G20210A mutations are associated with increased risk of deep venous thrombosis, pulmonary embolism, and obstetric complications. The development of inexpensive and reliable screening methods will assist in defining subpopulations of patients at risk who should undergo testing. We used a method, developed by Abbott Laboratories (Abbott Park, IL), to study 5,000 pregnant women and evaluated the association of obstetric complications with the presence of the FVL and PT G20210A mutations. We found a statistically significant association between FVL and stillbirth. There were also trends toward an association between FVL and placental abruption and between PT G20210A and intrauterine growth retardation. In addition, an association may exist between PT G20210A and preterm delivery for white women. All other parameters studied, including miscarriage and preeclampsia, did not show a statistically significant association with FVL or PT G20210A. These results confirm the association between genetic thrombophilia and selected obstetric complications.

Systemic inflammatory response syndrome, organ failure, and outcome in critically ill obstetric patients treated in an ICU.

STUDY OBJECTIVES: To determine the incidence of systemic inflammatory response syndrome (SIRS) and organ failure and to describe the outcomes in critically ill obstetric patients who have been treated in medical ICUs. DESIGN: Retrospective review. SETTING: A multidisciplinary ICU at a tertiary-care institution. METHODS: We collected data on 74 obstetric patients who were admitted consecutively to the ICU from January 1991 through December 1998. Acute physiology and chronic health evaluation (APACHE) II scores were calculated. A p value < 0.05 was considered to be significant. MEASUREMENTS AND RESULTS: Fifty-eight percent of patients were admitted to the ICU postpartum. Their mean (+/- SD) age was 25.9 +/- 7.0 years, and 64% were African American and 34% were white. Fifty percent had preexisting medical conditions. Their mean APACHE II score was 14.0 +/- 5.9, and their predicted mortality rate was 17.6%. The most common reason for admission was respiratory insufficiency. Preeclampsia was present in 38% of patients, and hemolytic anemia, elevated liver enzymes, and low platelet count syndrome were present in 7% of patients. SIRS developed in 59% of patients. Patients with SIRS had longer ICU stays (p = 0.0008). Organ failure developed in 65% of patients, and ARDS developed in 15% of patients. Invasive mechanical ventilation was required in 45% of patients, and pulmonary artery catheterization was required in 35% of patients. The in-hospital mortality rate was 2.7%. There were five spontaneous abortions and eight perinatal deaths. CONCLUSIONS: The most common reason for admission to the ICU of critically ill obstetric patients was respiratory failure. Despite the severity of illness and the development of SIRS and organ failure in most patients, the mortality rate was low.

Coagulation and fibrinolysis in viable mid-trimester pregnancies of normal, intrauterine growth retardation, chromosomal anomalies and hydrops fetalis and their eventual obstetric outcome.

A total of 71 pregnant women diagnosed by ultrasound to have viable fetus in late mid- trimester pregnancies of normal, IUGR, hydrops fetalis and chromosomal anomalies were studied for their coagulation, fibrinolytic and inhibitor levels with association on eventual obstetrics outcome. A hypercoagulable state was observed in all the pregnancies studied. However, higher hypercoagulation evidenced by significantly raised prothrombin formation and clot elasticity together with higher levels of D-dimer, uPA antigen and PAI-1 than observed in normal pregnancy suggests a hyperfibrinolytic/inhibitor state in hydrops fetalis pregnancy associated with bad obstetric outcome. In IUGR pregnancy associated with good outcome further enhanced clot elasticity was seen whilst no significant differences were observed in pregnancy with chromosomal anomalies when compared to uncomplicated normal pregnancy. Our study suggests that in hydrops fetalis pregnancy, further enhanced prothrombin formation and hyperfibrinolysis/inhibitor at late mid-trimester is associated with a poor obstetric outcome.

Relation of cervical length at 22-24 weeks of gestation to demographic characteristics and obstetric history.

Preterm delivery is the main cause of neonatal death and ultrasonographic cervical assessment has been shown to be more accurate than digital examination in recognizing a short cervix. This is a cross-sectional study, involving 1131 women at 22-24 weeks of pregnancy, designed to determine the distribution of cervical length and to examine which variables of demographic characteristics and obstetric history increase the risk of a short cervix (15 mm or less). The distribution of maternal demographic and obstetric history characteristics among patients with cervical length pound 15 mm was analyzed and compared to the findings for the general population. Risk ratios (RR) between subgroups were generated from this comparison. Median cervical length was 37 mm and in 1.5% of cases it was 15 mm or less. The proportion of women with a short cervix (< or =15 mm) was significantly higher among patients with a low body mass index (RR = 3.5) and in those with previous fetal losses between 16-23 weeks (RR = 33.1) or spontaneous preterm deliveries between 24-32 weeks (RR = 14.1). We suggest that transvaginal sonographic measurement of cervical length be performed as part of a routine midtrimester ultrasound evaluation. There are specific variables of demographic characteristics and obstetric history which increase the risk of detecting a short cervix at 22-24 weeks.

[History of obstetrics in nineteenth-century Brazil].

This research aimed at recovering the peculiarities of the development of Obstetrical Art in Brazil during XIX century, starting in 1808, when a legal act signed by D. Joao VI included this discipline in the initial curriculum of the schools of medicine and surgery founded in Bahia and Rio de Janeiro. Research was undertaken through the review of 83 medical theses in the field of Obstetrics, produced in Bahia and Rio de Janeiro in XIX century. The data showed that Obstetrical Art was traditionally performed by women called "aparadeiras" (catchers) or "comadres", who cared for women before, during and after delivery, and provided assistance in other situations, like venereal diseases and abortion. The inclusion of physicians-obstetricians in this practice led not only to a scrutinizing of the female body, but also to the production of an anatomical and physiological knowledge of the female organism from a male standpoint.

Obstetrical pulmonary embolism mortality, United States, 1970-85.

To investigate pulmonary embolism as a cause of obstetrical death, vital records data from 1970 through 1985 were analyzed. Results showed that the number of obstetrical pulmonary embolism deaths per 100,000 live births declined by 50 percent for both Whites and Blacks. However, Black women maintained more than a 2.5-fold higher risk, and women over age 40 had a ten-fold higher risk of embolism mortality. Thus, although the risk of obstetrical pulmonary embolism death has declined, some subgroups of women remain at higher risk.

Access to obstetric care in rural areas: effect on birth outcomes.

Hospital discharge data from 33 rural hospital service areas in Washington State were categorized by the extent to which patients left their local communities for obstetrical services. Women from communities with relatively few obstetrical providers in proportion to number of births were less likely to deliver in their local community hospital than women in rural communities with greater numbers of physicians practicing obstetrics in proportion to number of births. Women from these high-outflow communities had a greater proportion of complicated deliveries, higher rates of prematurity, and higher costs of neonatal care than women from communities where most patients delivered in the local hospital.

Obstetric care and payment source: do low-risk Medicaid women get less care?

OBJECTIVES: This study examined whether Medicaid-insured women at low risk receive less adequate obstetrical care than privately insured women. METHODS: Low-risk women who were cared for by a random sample of obstetrical providers in Washington State were randomly selected. Information on all prenatal and intrapartum services was abstracted from medical records. Service information was aggregated into standardized resource-use units. Results compared Medicaid-insured women with those who were privately insured. RESULTS: Medicaid-insured women were significantly younger (22.5 years vs 26.9 years) and averaged 6% fewer visits than privately insured women. Nonetheless, Medicaid status had no meaningful association with prenatal, intrapartum, or overall resource use. Some variation occurred in individual resources received. Medicaid-insured women had 38.8% more resources expended on testing for sexually transmitted diseases. Privately insured women had more resources expended on alpha-fetoprotein testing and on amniocentesis. There were no meaningful differences in birthweight or gestational age at delivery. CONCLUSIONS: In this study of women who entered obstetrical care at low risk, similar care and resources were expended on Medicaid-insured and on privately insured women.

Shoulder contracture and osseous deformity in obstetrical brachial plexus injuries.

BACKGROUND: The purposes of this study were to determine the prevalence of and the association between shoulder contracture and osseous deformity in a cohort of children with an obstetrical brachial plexus injury and to identify the risk factors for these complications. METHODS: In a retrospective cohort study, all children with an obstetrical brachial plexus injury who had been born between January 1991 and January 1998 at one academic medical center and all those with the same diagnosis who had been born elsewhere during the same period and were referred to the medical center within six weeks after delivery were evaluated at fixed time-intervals by one examiner. The patients underwent a final orthopaedic, neurological, and radiographic examination at a mean age of 3.7 years (range, one to seven years). Shoulder contracture was defined as a decrease in the passive range of motion in one or more directions compared with the range on the unaffected side. Osseous deformity was defined as a nonspherical humeral head or an abnormal glenoid. RESULTS: The prevalence of a shoulder contracture of >10 degrees was 56% (twenty-nine of fifty-two patients), and the prevalence of an osseous deformity was 33% (sixteen of forty-eight patients with complete radiographic follow-up). In the children in whom complete neurological recovery was delayed (i.e., recovery was more than three weeks after birth), the prevalence of shoulder contracture was 54% (thirteen of twenty-four patients) and the prevalence of osseous deformity was 26% (six of twenty-three patients). A strong association was noted between shoulder contracture and osseous deformity (p = 0.004). Directly after birth, the presence of a clavicular fracture was the only factor that was associated (p = 0.016) with the development of an osseous deformity (but not with a shoulder contracture). At a later stage, speed and extent of neurological recovery were related to shoulder contracture and osseous deformity. An asymmetric appearance was noticed in children who had a contracture, including those who had complete neurological recovery. CONCLUSIONS: The prevalence of shoulder contracture and osseous deformity in children with obstetrical brachial plexus injury was high, even in those with complete neurological recovery. These complications were strongly associated with one another. No symptom that appeared immediately after birth was identified as a factor that would predict the development of future shoulder contracture. A clavicular fracture was found to be significantly associated with the development of an osseous deformity at a later stage.
