Impacts of childbirth on anxiety, disability, and depression: Results from a Brazilian cohort

Conditions such as violence, drug abuse, sexual satisfaction, anxiety, depression, and disability interfere with a healthy pregnancy and can also account for maternal morbidity. The instrument WOICE was built by WHO to measure it. We applied WOICE in a prospective cohort of 125 pregnant women, using a before-after approach, during the third trimester of pregnancy, and after 42 until 90 days of childbirth. 60% had anxiety during pregnancy, decreasing to 48.8% after delivery (p = 0.07), and depression scores decreased from 7.56 to 5.80 (p = 0.014). Disability affected 62.4% and 56, respectively. 9.6% used drugs during pregnancy, reducing to 4.0% after delivery (RR 0.69, IC 0.49 - 0.69).

Twin pregnancy after kidney transplantation: case report and systematic review

BACKGROUND

Kidney transplantation is associated with fertility restoration in more than 50% of women with chronic kidney disease. Pregnancy after transplantation may affect women's health and fetal development, with higher rates of abortion, fetal growth restriction, and neonatal deaths. Twin pregnancy is a condition of high-risk for adverse maternal and perinatal outcomes, and its occurrence in women with previous kidney transplantation is rare.

CASE

32-year-old woman, recipient of living donor kidney transplantation, with a history of one pregnancy prior to transplantation, with current normal allograft function and no use of contraceptive method. At ten weeks of amenorrhea, ultrasound investigation showed a dichorionic diamniotic twin pregnancy. The following evaluation showed Chiari type II features in one fetus, and no detectable abnormality in the other one. There was appropriate blood pressure control with no need for an antihypertensive drug, and renal function remained normal without proteinuria. Calcium and a low dose of acetylsalicylic acid were used as preeclampsia prophylaxis. At 33 weeks of gestation, she presented premature rupture of membranes with spontaneous preterm labor. A cesarean section was performed due to the breech presentation of the first fetus. The patient persisted with normal graft function and without graft rejection during follow-up.

DISCUSSION AND CONCLUSION

Twin pregnancies after kidney transplantation are rare, and it is most frequently associated with preterm birth. We reported a successful twin pregnancy after kidney transplantation, with good perinatal and maternal outcomes, and without graft rejection or dysfunction.

Giving women WOICE postpartum: prevalence of maternal morbidity in high-risk pregnancies using the WHO-WOICE instrument

Background

There are no accurate estimates of the prevalence of non-severe maternal morbidities. Given the lack of instruments to fully assess these morbidities, the World Health Organization (WHO) developed an instrument called WOICE. We aimed to evaluate the prevalence of non-severe maternal morbidities in puerperal women and factors associated to impaired clinical, social and mental health conditions.

Method

A cross-sectional study with postpartum women at a high-risk outpatient clinic in southeast Brazil, from November 2017 to December 2018. The WOICE questionnaire included three sections: the first with maternal and obstetric history, sociodemographic data, risk and environment factors, violence and sexual health; the second considers functionality and disability, general symptoms and mental health; and the third includes data on physical and laboratory tests. Data collection was supported by Tablets with REDCAP software. Initially, a descriptive analysis was performed, with general prevalence of all variables contained in the WOICE, including scales on anxiety and depression (GAD-7 and PHQ-9- impaired if ≥10), functionality (WHODAS- high disability scores when ≥37.4) and data on violence and substance use. Subsequently, an evaluation of cases with positive findings was performed, with a Poisson regression to investigate factors associated to impaired non-clinical and clinical conditions.

Results

Five hundred seventeen women were included, majority (54.3%) multiparous, between 20 and 34 years (65.4%) and with a partner (75,6%). Over a quarter had (26.2%) preterm birth. Around a third (30.2%) reported health problems informed by the physician, although more than 80% considered having good or very good health. About 10% reported any substance use and 5.9% reported exposure to violence. Anxiety was identified in 19.8% of cases, depression in 36.9% and impaired functioning in 4.4% of women. Poisson regression identified that poor overall health rating was associated to increased anxiety/depression and impaired functioning. Having a partner reduced perception of women on the presence of clinical morbidities.

Conclusion

During postpartum care of a high-risk population, over one third of the considered women presented anxiety and depression; 10% reported substance use and around 6% exposure to violence. These aspects of women’s health need further evaluation and specific interventions to improve quality of care.

Maternal and Perinatal Outcomes of Pregnancies Complicated by Chronic Hypertension Followed at a Referral Hospital

OBJECTIVE

 To assess maternal and perinatal outcomes of pregnancies in women with chronic hypertension (CH).

METHODS

 Retrospective cohort of women with CH followed at a referral center for a 5 year period (2012-2017). Data were obtained from medical charts review and described as means and frequencies, and a Poisson regression was performed to identify factors independently associated to the occurrence of superimposed pre-eclampsia (sPE).

RESULTS

 A total of 385 women were included in the present study; the majority were > than 30 years old, multiparous, mostly white and obese before pregnancy. One third had pre-eclampsia (PE) in a previous pregnancy and 17% of them had organ damage associated with hypertension, mainly kidney dysfunction. A total of 85% of the patients used aspirin and calcium carbonate for pre-eclampsia prophylaxis and our frequency of sPE was 40%, with an early onset (32.98 ± 6.14 weeks). Of those, 40% had severe features of PE, including 5 cases of HELLP syndrome; however, no cases of eclampsia or maternal death were reported. C-section incidence was high, gestational age at birth was 36 weeks, and nearly a third (115 cases) of newborns had complications at birth One third of the women remained using antihypertensive drugs after pregnancy.

CONCLUSION

 Chronic hypertension is related with the high occurrence of PE, C-sections, prematurity and neonatal complications. Close surveillance and multidisciplinary care are important for early diagnosis of complications.

Pregnancy Among Women with Kidney Transplantation: A 20-Years Single-Center Registry

OBJECTIVE

 To assess maternal and perinatal outcomes in pregnancies after kidney transplantation in a tertiary center in Brazil.

METHODS

 Retrospective cohort of pregnancies in women with kidney transplantation at the Universidade Estadual de Campinas, from January 1995 until December 2017. Medical charts were reviewed, and maternal and perinatal outcomes were described as means and frequencies. Renal function and blood pressure were evaluated during pregnancy and postpartum.

RESULTS

 A total of 22 women had at least 1 pregnancy during the considered time interval, and 3 of them had > 1 pregnancy, totalizing 25 pregnancies. The mean age at transplantation was of 24.6 ± 4.2 years old, and the mean time interval until pregnancy was of 67.8 ± 46.3 months. The most frequent complication during pregnancy was hypertension, which affected 11 (64.7%) women. The gestational age at delivery was 34.7 ± 4 weeks, and 47% of these pregnancies were preterm (< 37 weeks). A total of 88.2% of the women delivered by cesarean section. Renal function, measured by serum creatinine, remained stable during pregnancy, and the systolic blood pressure increased significantly, while the diastolic blood pressure did not differ during pregnancy.

CONCLUSION

 Pregnancy after kidney transplantation is a rare event. Pre-eclampsia and prematurity were frequent complications, and cesarean section rates were very high. A specialized antenatal and postpartum care with a multiprofessional approach and continuous monitoring of graft function are essential for the early diagnosis of complications and improved outcomes.

Lessons from the Field Beyond the Numbers: Narratives of Professionals on Women who Experienced Severe Maternal Morbidity

OBJECTIVE

 Several factors might affect the health and the quality of life of women who had a severe maternal morbidity (SMM) or a maternal near-miss (MNM) episode. The objective of the present study was to explore the perspectives of the professionals on the repercussions of SMM or of MNM after interviewing women who survived such episodes.

METHOD

 Selected cases that captured the attention of professionals were reported. The professionals built individually 10 narratives, which were analyzed with the technique of content analysis.

RESULTS

 According to the perspectives of the professionals, women surviving a severe maternal condition and their families experienced clinical and psychosocial consequences. Some cases portrayed the intense psychological distress in mourning for the loss of the fetus or of their reproductive capacity and changes in family dynamics generating emotional overload, depression, and gender violence.

CONCLUSION

 The analysis of narratives may offer an idea on the complexity of the perception of care by professionals and on the need for an interdisciplinary follow-up of women surviving an SMM or an MNM episode.

Drug Use during Pregnancy and its Consequences: A Nested Case Control Study on Severe Maternal Morbidity

OBJECTIVE

 To assess the relationship between the use of psychoactive substances during pregnancy and the occurrence of severe maternal morbidity (SMM), perinatal outcomes and repercussions on the neuropsychomotor development of exposed children.

METHODS

 A case-control study nested within a cohort of severe maternal morbidity (COMMAG) was performed. Women with SMM were considered cases. Controls were those with low-risk pregnancy, without SMM and admitted during the same time period as the cases. Cohort data were collected retrospectively in hospital records for childbirth. A face-to-face interview was also performed with 638 women (323 without SMM and 315 with SMM) and their children of the index pregnancy between 6 months and 5 years after childbirth. During the interview, substance abuse during pregnancy was assessed by a modified question from the Alcohol, Smoking and Substance Involvement Screening Test 2.0 (ASSIST) and the neuropsychomotor development in the children was assessed by the Denver Developmental Screening Test, 2^nd edition.

RESULTS

 The prevalence of licit or illicit drug use during pregnancy was ∼ 17%. Among drug users, 63.9% used alcohol, 58.3% used tobacco, 9.2% used cocaine/crack and 4.6% used marijuana. There was no association between drug use during pregnancy and SMM, although tobacco use during pregnancy was associated with bleeding, presence of near-miss clinical criteria (NMCC) and alteration in infant development; alcohol use was associated with neonatal asphyxia; and cocaine/crack use was associated with the occurrence of some clinical complications during pregnancy.

CONCLUSION

 The use of psychoactive substances during pregnancy is frequent and associated with worse maternal, perinatal and child development outcomes.

A Critical Review on Obstetric Follow-up of Women Affected by Systemic Lupus Erythematosus

OBJECTIVE

 To review the existing recommendations on the prenatal care of women with systemic lupus erythematosus (SLE), based on currently available scientific evidence.

METHODS

 An integrative review was performed by two independent researchers, based on the literature available in the MEDLINE (via PubMed), EMBASE and The Cochrane Library databases, using the medical subject headings (MeSH) terms "systemic lupus erythematosus" AND "high-risk pregnancy" OR "prenatal care." Studies published in English between 2007 and 2017 were included; experimental studies and case reports were excluded. In cases of disagreement regarding the inclusion of studies, a third senior researcher was consulted. Forty titles were initially identified; four duplicates were excluded. After reading the abstracts, 7 were further excluded and 29 were selected for a full-text evaluation.

RESULTS

 Systemic lupus erythematosus flares, preeclampsia, gestation loss, preterm birth, fetal growth restriction and neonatal lupus syndromes (mainly congenital heart-block) were the major complications described. The multidisciplinary team should adopt a specific monitoring, with particular therapeutic protocols. There are safe and effective drug options that should be prescribed for a good control of SLE activity.

CONCLUSION

 Pregnant women with SLE present an increased risk for maternal complications, pregnancy loss and other adverse outcomes. The disease activity may worsen and, thereby, increase the risk of other maternal-fetal complications. Thus, maintaining an adequate control of disease activity and treating flares quickly should be a central goal during prenatal care.

The Burden of Indirect Causes of Maternal Morbidity and Mortality in the Process of Obstetric Transition: A Cross-Sectional Multicenter Study

OBJECTIVE

 The aim of this study is to evaluate the burden of indirect causes of maternal morbidity/mortality in Brazil.

METHODS

 Secondary analysis of a multicenter cross-sectional study conducted in 27 referral obstetric units within the Brazilian Network for Surveillance of Severe Maternal Morbidity.

RESULTS

 A total of 82,388 women were surveilled: 9,555 women with severe maternal morbidity were included, and 942 (9.9%) of them had indirect causes of morbidity/mortality. There was an increased risk of higher severity among the indirect causes group, which presented 7.56 times increased risk of maternal death (prevalence ratio [PR]: 7.56; 95% confidence interval [95%CI]: 4.99-11.45). The main indirect causes of maternal death were H1N1 influenza, sepsis, cancer and cardiovascular disease. Non-public antenatal care (PR: 2.52; 95%CI: 1.70-3.74), diabetes (PR: 1.90; 95%CI: 1.24-2.90), neoplasia (PR: 1.98; 95%CI: 1.25-3.14), kidney diseases (PR: 1.99; 95%CI: 1.14-3.49), sickle cell anemia (PR: 2.50; 95%CI: 1.16-5.41) and drug addiction (PR: 1.98; 95%CI: 1.03-3.80) were independently associated with worse results in the indirect causes group. Some procedures for the management of severity were more common for the indirect causes group.

CONCLUSION

 Indirect causes were present in less than 10% of the overall cases, but they represented over 40% of maternal deaths in the current study. Indirect causes of maternal morbidity/mortality were also responsible for an increased risk of higher severity, and they were associated with worse maternal and perinatal outcomes. In middle-income countries there is a mix of indirect causes of maternal morbidity/mortality that points to some advances in the scale of obstetric transition, but also reveals the fragility of health systems.

Obstetrician's risk perception on the prescription of magnesium sulfate in severe preeclampsia and eclampsia: A qualitative study in Brazil

Introduction

Magnesium sulfate (MgSO₄) is the drug of choice for the prevention and control of seizures in the management of severe preeclampsia/eclampsia. Several barriers have been identified in the use of MgSO₄, especially in low and middle-income settings.

Objective

To describe the obstetrician’s perception on possible reasons for underutilizing magnesium sulfate to treat preeclampsia/eclampsia.

Method

A qualitative clinical study, based on phenomenological reference by semi-structured interviews and open-ended discussions with obstetricians of the public healthcare system in primary care units (PCU) and referral maternity hospitals (RMH), in a southeastern Brazilian city.

Results

Fear of drug toxicity was the major cause for not prescribing the medication in PCU. Fear was justified by insufficient technical, structural and organizational resources of healthcare facilities and by a shortage of physicians properly trained for adequate drug use.

Conclusion

Fear of toxicity of magnesium sulfate was the main barrier towards timely and proper drug use. Periodic skill development and training of obstetricians, along with integration of the medical team in the work environment may contribute to decrease fear, ensuring safety of drug prescription and thus possibly reducing adverse outcomes related to PE.

Situational analysis of facilitators and barriers to availability and utilization of magnesium sulfate for eclampsia and severe preeclampsia in the public health system in Brazil

BACKGROUND

Eclampsia is the main cause of maternal death in Brazil. Magnesium sulfate is the drug of choice for seizure prevention and control in the management of severe preeclampsia and eclampsia. Despite scientific evidence demonstrating its effectiveness and safety, there have been delays in managing hypertensive disorders, including timely access to magnesium sulfate. To conduct a general situational analysis on availability and use of magnesium sulfate for severe preeclampsia and eclampsia in the public health system.

METHOD

A situational analysis was conducted with two components: a documental analysis on information available at the official websites on the policy, regulation and availability of the medication, plus a cross sectional study with field analysis and interviews with local managers of public obstetric health services in Campinas, in the southeast of Brazil. We used the fishbone cause and effect diagram to organize study components. Interviews with managers were held during field observations using specific questionnaires.

RESULTS

There was no access to magnesium sulfate in primary care facilities, obstetric care was excluded from urgency services and clinical protocols for professional guidance on the adequate use of magnesium sulfate were lacking in the emergency mobile care service. Magnesium sulfate is currently only administered in referral maternity hospitals.

CONCLUSION

The lack of processes that promote the integration between urgency/emergency care and specialized obstetric care possibly favors the untimely use of magnesium sulfate and contributes to the high maternal morbidity/mortality rates.

Severe maternal morbidity due to respiratory disease and impact of 2009 H1N1 influenza A pandemic in Brazil: results from a national multicenter cross-sectional study

BACKGROUND

The aim of this study was to assess the burden of respiratory disease, considering the influenza A pandemic season (H1N1pdm09), within the Brazilian Network for Surveillance of Severe Maternal Morbidity, and factors associated with worse maternal outcome.

METHODS

A multicenter cross-sectional study, involving 27 referral maternity hospitals in five Brazilian regions. Cases were identified in a prospective surveillance by using the WHO standardized criteria for potentially life-threatening conditions (PLTC) and maternal near miss (MNM). Women with severe complications from respiratory disease identified as suspected or confirmed cases of H1N1 influenza or respiratory failure were compared to those with other causes of severe morbidity. A review of suspected H1N1 influenza cases classified women as non-tested, tested positive and tested negative, comparing their outcomes. Factors associated with severe maternal outcome (SMO = MNM + MD) were assessed in both groups, in comparison to PLTC, using PR and 95 % CI adjusted for design effect of cluster sampling.

RESULTS

Among 9555 cases of severe maternal morbidity, 485 (5 %) had respiratory disease. Respiratory disease occurred in one-quarter of MNM cases and two-thirds of MD. H1N1 virus was suspected in 206 cases with respiratory illness. Around 60 % of these women were tested, yielding 49 confirmed cases. Confirmed H1N1 influenza cases had worse adverse outcomes (MNM:MD ratio < 1 (0.9:1), compared to 12:1 in cases due to other causes), and a mortality index > 50 %, in comparison to 7.4 % in other causes of severe maternal morbidity. Delay in medical care was associated with SMO in all cases considered, with a two-fold increased risk among respiratory disease patients. Perinatal outcome was worse in cases complicated by respiratory disease, with increased prematurity, stillbirth, low birth weight and Apgar score < 7.

CONCLUSIONS

Respiratory disease, especially considering the influenza season, is a very severe cause of maternal near miss and death. Increased awareness about this condition, preventive vaccination during pregnancy, early diagnosis and treatment are required to improve maternal health.

The role of infection and sepsis in the Brazilian Network for Surveillance of Severe Maternal Morbidity

OBJECTIVE

To identify the burden of severe infection within the Brazilian Network for Surveillance of Severe Maternal Morbidity and factors associated with worse maternal outcomes.

METHODS

This was a multicentre cross-sectional study involving 27 referral maternity hospitals in Brazil. WHO's standardised criteria for potentially life-threatening conditions and maternal near miss were used to identify cases through prospective surveillance and the main cause of morbidity was identified as infection or other causes (hypertension, haemorrhage or clinical/surgical). Complications due to infection were compared to complications due to the remaining causes of morbidity. Factors associated with a severe maternal outcome were assessed for the cases of infection.

RESULTS

A total of 502 (5.3%) cases of maternal morbidity were associated with severe infection vs. 9053 cases (94.7%) with other causes. Considering increased severity of cases, infection was responsible for one-fourth of all maternal near miss (23.6%) and nearly half (46.4%) of maternal deaths, with a maternal near miss to maternal death ratio three times (2.8:1) that of cases without infection (7.8:1) and a high mortality index (26.3%). Within cases of infection, substandard care was present in over one half of the severe maternal outcome cases. Factors independently associated with worse maternal outcomes were HIV/AIDS, hysterectomy, prolonged hospitalisation, intensive care admission and delays in medical care.

CONCLUSIONS

Infection is an alarming cause of maternal morbidity and mortality and timely diagnosis and adequate management are key to improving outcomes during pregnancy. Delays should be addressed, risk factors identified, and specific protocols of surveillance and care developed for use during pregnancy.

Network for Surveillance of Severe Maternal Morbidity: a powerful national collaboration generating data on maternal health outcomes and care

OBJECTIVE

To identify cases of severe maternal morbidity (SMM) during pregnancy and childbirth, their characteristics, and to test the feasibility of scaling up World Health Organization criteria for identifying women at risk of a worse outcome.

DESIGN

Multicentre cross-sectional study.

SETTING

Twenty-seven referral maternity hospitals from all regions of Brazil.

POPULATION

Cases of SMM identified among 82 388 delivering women over a 1-year period.

METHODS

Prospective surveillance using the World Health Organization's criteria for potentially life-threatening conditions (PLTC) and maternal near-miss (MNM) identified and assessed cases with severe morbidity or death.

MAIN OUTCOME MEASURES

Indicators of maternal morbidity and mortality; sociodemographic, clinical and obstetric characteristics; gestational and perinatal outcomes; main causes of morbidity and delays in care.

RESULTS

Among 9555 cases of SMM, there were 140 deaths and 770 cases of MNM. The main determining cause of maternal complication was hypertensive disease. Criteria for MNM conditions were more frequent as the severity of the outcome increased, all combined in over 75% of maternal deaths.

CONCLUSIONS

This study identified around 9.5% of MNM or death among all cases developing any severe maternal complication. Multicentre studies on surveillance of SMM, with organised collaboration and adequate study protocols can be successfully implemented, even in low-income and middle-income settings, generating important information on maternal health and care to be used to implement appropriate health policies and interventions.

TWEETABLE ABSTRACT

Surveillance of severe maternal morbidity was proved to be possible in a hospital network in Brazil.

[Beta thalassemia major and pregnancy during adolescence: report of two cases]

Beta thalassemia major is a rare hereditary blood disease in which impaired synthesis of beta globin chains causes severe anemia. Medical treatment consists of chronic blood transfusions and iron chelation. We describe two cases of adolescents with beta thalassemia major with unplanned pregnancies and late onset of prenatal care. One had worsening of anemia with increased transfusional requirement, fetal growth restriction, and placental senescence. The other was also diagnosed with hypothyroidism and low maternal weight, and was admitted twice during pregnancy due to dengue shock syndrome and influenza H1N1-associated respiratory infection. She also developed fetal growth restriction and underwent vaginal delivery at term complicated by uterine hypotonia. Both patients required blood transfusions after birth and chose medroxyprogesterone as a contraceptive method afterwards. This report highlights the importance of medical advice on contraceptive methods for these women and the role of a specialized prenatal follow-up in association with a hematologist.

Robson Ten Group Classification System applied to women with severe maternal morbidity

OBJECTIVE

To evaluate the distribution of women with severe maternal morbidity according to Robson Ten Group Classification System (RTGCS).

METHODS

Secondary analysis of a multicenter cross-sectional study in 27 obstetric units in Brazil, using RTGCS. Cases were classified into potentially life-threatening condition or a maternal near miss or death, according to severity. Certain groups were subdivided for further analysis. Cesarean delivery (CD) rates were reported.

RESULTS

Among 7,247 women with severe maternal morbidity, 73.2 percent underwent CD. Group 10 (single, cephalic, preterm) was the most prevalent (33.9%). Groups mostly associated with a severe maternal outcome were: 7 (multiparous, breech), 9 (all abnormal lies, single, term), 8 (all multiple), and 10. Groups 1 (nulliparous, single, cephalic, term, spontaneous) and 3 (multiparous, single, cephalic, term, spontaneous) were associated with better maternal outcome. Group 3 had one severe maternal morbidity to 29 cases of potentially life-threatening, but the ratio was 1:10 for women undergoing CD, indicating a worse outcome. Group 4a (multiparous, no previous CD, single, cephalic, term, induced labor) had a better maternal outcome than those delivered by CD before labor (group 4b). Hypertension was the most common condition of severity.

CONCLUSIONS

The RTGCS was useful to consider severe maternal morbidity, showing groups with higher CD rates and worse maternal outcomes.

Severe maternal morbidity and maternal near miss in the extremes of reproductive age: results from a national cross- sectional multicenter study

Background

The aim of this study was to assess severe maternal morbidity (SMM) and near miss (NM) cases among adolescent girls and women over 35 years of age in the Brazilian Network for Surveillance of Severe Maternal Morbidity, using a set of standard criteria, compared to pregnant women aged 20 to 34 years.

Methods

A cross-sectional multicenter study conducted in 27 referral obstetric units in Brazil. All pregnant women admitted to these centers during a one-year period of prospective surveillance were screened to identify cases of maternal death (MD), NM and other SMM. Indicators of maternal morbidity and mortality were evaluated for the three age groups. Sociodemographic, clinical and obstetric characteristics, gestational and perinatal outcomes, main causes of morbidity and delays in care were also compared. Two multiple analysis models were performed, to estimate the adjusted prevalence ratio for identified factors that were independently associated with the occurrence of severe maternal outcome (SMO = MNM + MD).

Results

Among SMM and MD cases identified, the proportion of adolescent girls and older women were 17% each. The risk of MNM or death was 25% higher among older women. Maternal near miss ratio and maternal mortality ratios increased with age, but these ratios were also higher among adolescents aged 10 to 14, although the absolute numbers were low. On multivariate analysis, younger age was not identified as an independent risk factor for SMO, while this was true for older age (PR 1.25; 1.07-1.45).

Conclusions

SMO was high among women below 14 years of age and increased with age in Brazilian pregnant women.

Maternal near miss and death among women with severe hypertensive disorders: a Brazilian multicenter surveillance study

BACKGROUND

Hypertensive disorders represent the major cause of maternal morbidity in middle income countries. The main objective of this study was to identify the prevalence and factors associated with severe maternal outcomes in women with severe hypertensive disorders.

METHODS

This was a cross-sectional, multicenter study, including 6706 women with severe hypertensive disorder from 27 maternity hospitals in Brazil. A prospective surveillance of severe maternal morbidity with data collected from medical charts and entered into OpenClinica®, an online system, over a one-year period (2009 to 2010). Women with severe preeclampsia, severe hypertension, eclampsia and HELLP syndrome were included in the study. They were grouped according to outcome in near miss, maternal death and potentially life-threatening condition. Prevalence ratios and 95% confidence intervals adjusted for cluster effect for maternal and perinatal variables and delays in receiving obstetric care were calculated as risk estimates of maternal complications having a severe maternal outcome (near miss or death). Poisson multiple regression analysis was also performed.

RESULTS

Severe hypertensive disorders were the main cause of severe maternal morbidity (6706/9555); the prevalence of near miss was 4.2 cases per 1000 live births, there were 8.3 cases of Near Miss to 1 Maternal Death and the mortality index was 10.7% (case fatality). Early onset of the disease and postpartum hemorrhage were independent variables associated with severe maternal outcomes, in addition to acute pulmonary edema, previous heart disease and delays in receiving secondary and tertiary care.

CONCLUSIONS

In women with severe hypertensive disorders, the current study identified situations independently associated with a severe maternal outcome, which could be modified by interventions in obstetric care and in the healthcare system. Furthermore, the study showed the feasibility of a hospital system for surveillance of severe maternal morbidity.

The WHO maternal near-miss approach and the maternal severity index model (MSI): tools for assessing the management of severe maternal morbidity

OBJECTIVES

To validate the WHO maternal near-miss criteria and develop a benchmark tool for severe maternal morbidity assessments.

METHODS

In a multicenter cross-sectional study implemented in 27 referral maternity hospitals in Brazil, a one-year prospective surveillance on severe maternal morbidity and data collection was carried out. Diagnostic accuracy tests were used to assess the validity of the WHO maternal near-miss criteria. Binary logistic regression was used to model the death probability among women with severe maternal complications and benchmark the management of severe maternal morbidity.

RESULTS

Of the 82,388 women having deliveries in the participating health facilities, 9,555 women presented pregnancy-related complications, including 140 maternal deaths and 770 maternal near misses. The WHO maternal near-miss criteria were found to be accurate and highly associated with maternal deaths (Positive likelihood ratio 106.8 (95% CI 99.56-114.6)). The maternal severity index (MSI) model was developed and found to able to describe the relationship between life-threatening conditions and mortality (Area under the ROC curve: 0.951 (95% CI 0.909-0.993)).

CONCLUSION

The identification of maternal near-miss cases using the WHO list of pregnancy-related life-threatening conditions was validated. The MSI model can be used as a tool for benchmarking the performance of health services managing women with severe maternal complications and provide case-mix adjustment.

Computer-assisted telephone interviewing (CATI): using the telephone for obtaining information on reproductive health

The objective of this study was to evaluate the feasibility of using computer assisted telephone interviewing (CATI) as a method for obtaining information on reproductive health in Brazil. A total of 998 eligible women for the study were selected to answer a questionnaire through computer- assisted telephone interviewing undertaken by trained interviewers. The outcomes of each telephone contact attempt were described. Differences between groups were assessed using the χ(2) test. Phone contact was made in 60.3% of the attempts and 57.5% of the interviews were completed. The success rate improved with the decrease in time from hospitalization to interview and with the higher numbers of telephones available. A total of 2,170 calls were made, comprising of one to sixteen attempts per woman. The majority of situations where extra calls were necessary were due to the number being busy or to the fact that the woman was not available at the time of the call. CATI can prove be a valuable procedure for obtaining information on reproductive health among Brazilian women, particularly for relatively recent events and when more than one alternative telephone number is available.

Applying the new concept of maternal near-miss in an intensive care unit

OBJECTIVES

The World Health Organization has recommended investigating near-misses as a benchmark practice for monitoring maternal healthcare and has standardized the criteria for diagnosis. We aimed to study maternal morbidity and mortality among women admitted to a general intensive care unit during pregnancy or in the postpartum period, using the new World Health Organization criteria.

METHODS

In a cross-sectional study, 158 cases of severe maternal morbidity were classified according to their outcomes: death, maternal near-miss, and potentially life-threatening conditions. The health indicators for obstetrical care were calculated. A bivariate analysis was performed using the Chi-square test with Yate's correction or Fisher's exact test. A multiple regression analysis was used to calculate the crude and adjusted odds ratios, together with their respective 95% confidence intervals.

RESULTS

Among the 158 admissions, 5 deaths, 43 cases of maternal near-miss, and 110 cases of potentially life-threatening conditions occurred. The near-miss rate was 4.4 cases per 1,000 live births. The near-miss/death ratio was 8.6 near-misses for each maternal death, and the overall mortality index was 10.4%. Hypertensive syndromes were the main cause of admission (67.7% of the cases, 107/158); however, hemorrhage, mainly due to uterine atony and ectopic pregnancy complications, was the main cause of maternal near-misses and deaths (17/43 cases of near-miss and 2/5 deaths).

CONCLUSIONS

Hypertension was the main cause of admission and of potentially life-threatening conditions; however, hemorrhage was the main cause of maternal near-misses and deaths at this institution, suggesting that delays may occur in implementing appropriate obstetrical care.

Elective induction versus spontaneous labour in Latin America

OBJECTIVE

To assess the frequency of elective induction of labour and its determinants in selected Latin America countries; quantify success in attaining vaginal delivery, and compare rates of caesarean and adverse maternal and perinatal outcomes after elective induction versus spontaneous labour in low-risk pregnancies.

METHODS

Of 37,444 deliveries in women with low-risk pregnancies, 1847 (4.9%) were electively induced. The factors associated with adverse maternal and perinatal outcomes among cases of spontaneous and induced onset of labour were compared. Odds ratios for factors potentially associated with adverse outcomes were calculated, as were the relative risks of having an adverse maternal or perinatal outcome (both with their 95% confidence intervals). Adjustment using multiple logistic regression models followed these analyses.

FINDINGS

Of 11,077 cases of induced labour, 1847 (16.7%) were elective. Elective inductions occurred in 4.9% of women with low-risk pregnancies (37,444). Oxytocin was the most common method used (83% of cases), either alone or combined with another. Of induced deliveries, 88.2% were vaginal. The most common maternal adverse events were: (i) a higher postpartum need for uterotonic drugs, (ii) a nearly threefold risk of admission to the intensive care unit; (iii) a fivefold risk of postpartum hysterectomy, and (iv) an increased need for anaesthesia/analgesia. Perinatal outcomes were satisfactory except for a 22% higher risk of delayed breastfeeding (i.e. initiation between 1 hour and 7 days postpartum).

CONCLUSION

Caution is mandatory when indicating elective labour induction because the increased risk of maternal and perinatal adverse outcomes is not outweighed by clear benefits.

Maternal morbidity and near miss in the community: findings from the 2006 Brazilian demographic health survey

OBJECTIVE

To obtain an estimate of the prevalence of potentially life-threatening maternal conditions and near-miss events in Brazil, and to explore the factors associated with these complications.

DESIGN

A demographic health survey (DHS) focusing on reported maternal complications.

SETTING

Data from the five geographical regions of Brazil.

POPULATION

A total of 5025 women with at least one live birth in the 5-year reference period preceding their interview in the DHS.

METHODS

A secondary analysis of the 2006 Brazilian DHS database was carried out using a validated questionnaire to evaluate the occurrence of maternal complications and related key interventions. According to a pragmatic definition, any woman reporting the occurrence of eclampsia, hysterectomy, blood transfusion or admission to the intensive care unit was considered as having experienced a near-miss event. Associations between the sociodemographic characteristics of the women and severe maternal morbidity were evaluated.

MAIN OUTCOME MEASURES

Proportions and ratios of complications and related interventions defined as maternal near miss in pregnancy, and estimated risk factors for maternal morbidities.

RESULTS

Around 22% of women reported complications during pregnancy. The prevalence of maternal near miss in Brazil, using the pragmatic definition, was 21.1 per 1000 live births. An increased risk of severe maternal morbidity was found in women aged ≥40 years and in those with low levels of education.

CONCLUSIONS

Nearly 70,000 maternal near-miss cases and approximately 750,000 cases with potentially life-threatening conditions are estimated to occur in Brazil per year. A pragmatic definition of maternal near miss was useful to obtain more reliable information at the community level. This approach could be used to gather information on maternal morbidity in settings in which such data are not routinely collected.

[Comparison of two methods for the investigation of maternal mortality in a municipality of the Brazilian southeast]

PURPOSE

to compare maternal death data from the National Death Information System (DIS), with a death survey of 10 to 49 year-old women at reproductive age (RAMOS), in order to identify sub-notification and to search for causes of maternal death (MD) from 1999 to 2006.

METHODS

population based temporal series taken from death certificate (DC) information from Fundação Sistema Estadual de Análise de Dados (SEADE) database, with the death causes codified by the International Classification of Diseases (ICD), tenth revision, and the number of born alive babies (BA). Death was categorized into declared, presumptive MD and non-maternal. The identification of cases was done from a list with both the birth and death dates in the municipal morgues, and further information was obtained in the epidemiological sector of the Municipal Committee of Surveillance of Maternal Death (MCSMD). Information on MD was raised in the DIS. Sub-notification rates in cases of declared and non-declared MD were identified, maternal official death rates (MDR) and the adjusted factor for the period were calculated and corrected, and MD cases were reviewed and classified.

RESULTS

twelve MD were identified, six of them declared and six non-declared. Sub-notification rate was 50%, giving an adjusting factor equal to 2. The official MDR was 14.7 and the corrected one was 29.4 deaths by 100,000 born alive. In most of the cases, the basic causes of death were mistaken. Direct obstetric causes were more prevalent, among them eclampsia and HELLP syndrome, followed by infections.

CONCLUSIONS

political and administrative measures are needed for the effective action of MD survey committees. The prevalence of direct obstetric causes indicates failures in maternal and perinatal care.

Factors and outcomes associated with the induction of labour in Latin America

OBJECTIVE

To describe the prevalence of labour induction, together with its risk factors and outcomes in Latin America.

DESIGN

Analysis of the 2005 WHO global survey database.

SETTING

Eight selected Latin American countries.

POPULATION

All women who gave birth during the study period in 120 participating institutions.

METHODS

Bivariate and multivariate analyses.

MAIN OUTCOME MEASURES

Indications for labour induction per country, success rate per method, risk factors for induction, and maternal and perinatal outcomes.

RESULTS

Of the 97,095 deliveries included in the survey, 11,077 (11.4%) were induced, with 74.2% occurring in public institutions, 20.9% in social security hospitals and 4.9% in private institutions. Induction rates ranged from 5.1% in Peru to 20.1% in Cuba. The main indications were premature rupture of membranes (25.3%) and elective induction (28.9%). The success rate of vaginal delivery was very similar for oxytocin (69.9%) and misoprostol (74.8%), with an overall success rate of 70.4%. Induced labour was more common in women over 35 years of age. Maternal complications included higher rates of perineal laceration, need for uterotonic agents, hysterectomy, ICU admission, hospital stay>7 days and increased need for anaesthetic/analgesic procedures. Some adverse perinatal outcomes were also higher: low 5-minute Apgar score, very low birthweight, admission to neonatal ICU and delayed initiation of breastfeeding.

CONCLUSIONS

In Latin America, labour was induced in slightly more than 10% of deliveries; success rates were high irrespective of the method used. Induced labour is, however, associated with poorer maternal and perinatal outcomes than spontaneous labour.

[Cervical bacterial colonization in women with preterm labor or premature rupture of membranes]

PURPOSE

to study cervical colonization in women with preterm labor or premature rupture of membranes.

METHODS

two hundred and twelve pregnant women with preterm labor or premature rupture of membranes were studied. Two cervical samples from each woman were collected and bacterioscopy and culture were performed. Association of cervical microorganisms and urinary tract infection, chorioamnionitis, fetal stress, antibiotic use, prematurity, neonatal infection, and neonatal death were evaluated.

RESULTS

the prevalence of endocervical colonization was 14.2% (CI95%=9.5-18.9%), with similar results in preterm labor or premature rupture of membranes. Group B streptococcus was the most prevalent organism (9.4%). Other organisms isolated were Candida sp, Streptococcus sp, Streptococcus pneumoniae, Escherichia coli and Enterococcus sp. The most common findings of bacterioscopy were a reduced number of lactobacilli and a great number of leukocytes. Endocervical colonization was associated with a higher occurrence of urinary tract infection (23.8 versus 5.4%; p<0.01), early-onset neonatal infection (25.0 versus 7.3%; p<0.01) and neonatal mortality (two cases in colonized women; p<0.02) when compared with a negative culture of endocervical mucus.

CONCLUSIONS

this study showed high prevalence of endocervical colonization despite the use of a nonselective culture media. The main microorganism isolated was group B streptococcus, but other organisms were present in one third of the studied population. More studies are needed to evaluate the influence of endocervical colonization on obstetrical outcome and on neonatal infection and mortality.

Self-reported maternal morbidity and associated factors among Brazilian women

PURPOSE

Demographic health surveys may constitute a valuable source of information on maternal morbidity, particularly in locations where an integrated system of epidemiological surveillance with wide geographic coverage has not yet been developed.

METHODS

This study analyzed the database obtained from a national Demographic Health Survey carried out in Brasil in 1996. Data regarding how the survey was conducted, characteristics of the women interviewed who had given birth to live infants in the five preceding years, characteristics of the obstetrical care received and complications reported were evaluated.

RESULTS

Responses from a weighted total of 3,635 women were analyzed. Statistically significant differences (p<0.001) were found between geographic domains for most characteristics studied. Deliveries were predominantly hospital-based throughout the whole country. Prevalence of self-reported maternal morbidity ranged from 15.5-22.9% in the various geographic domains analyzed. This geographic factor was found to be associated to differences in the occurrence of complications, generally and specifically, for cases of prolonged labour.

CONCLUSION

Differences in morbidity may reflect the intricate relationship between determinants of human development and maternal health conditions.

[Using quantitative and qualitative approaches in knowledge production]

The debate over the differences between quantitative and qualitative methods is frequent, holding favorable and opposite positions concerning their integration. Outlining a research that contemplates both approaches generates doubts and restlessness about how to use them without damaging the methods' rigor, specificity, as well as the methodological and reflective sophistication of each. The purpose isto report and discuss using the quantitative (randomized controlled clinical trial) and the qualitative approach to analyze and understand the practice of including a companion chosen by the woman during her labor and childbirth, performing the role of support provider. Using both methods allowed for approximating the multiple facets involved in this practice and evaluating both the explicative dimension and the comprehension, since it could be performed with complementary views.

[Obstetric care and severe pregnancy complications in Latin America and the Caribbean: an analysis of information from demographic health surveys]

OBJECTIVE

To compile, consolidate, and analyze information obtained in surveys conducted by the MEASURE DHS [Demographic and Health Surveys] program, concerning obstetric care and pregnancy complications for women in Latin America and the Caribbean, in the five years before the survey.

METHODS

This exploratory study utilized data from demographic surveys carried out in the 1990s in seven countries of Latin America: Bolivia, Brazil, Colombia, the Dominican Republic, Guatemala, Nicaragua, and Peru. The study describes the characteristics of the women who were interviewed and of the obstetric care that they received in the five years before the respective survey, and it also estimates the occurrence of prolonged labor and of hemorrhagic, hypertensive, and infectious complications in those five years.

RESULTS

The median number of prenatal consultations ranged from 4.7 in Bolivia to 6.6 in the Dominican Republic. More than 40% of deliveries in Guatemala, Peru, and Bolivia were attended by traditional midwives, relatives, or other persons without formal training. The highest rates of deliveries performed in health care facilities (> 90%) were in the Dominican Republic and Brazil. In Guatemala, Peru, and Bolivia more than 45% of deliveries were at home. The highest rate of cesarean delivery was in Brazil (36.4%), and the lowest rates (< 12%) were in Peru and Guatemala. The rate of pregnancy complications reported by the women surveyed was 16.7% in Brazil, 17.9% in Guatemala, 42.1% in Colombia, 42.5% in Nicaragua, 43.0% in the Dominican Republic, 51.7% in Bolivia, and 51.8% in Peru.

CONCLUSION

The reported occurrence of severe pregnancy complications in the surveys we examined was well above the 15% rate reported in other scientific literature, suggesting that these complications may have been overestimated in the MEASURE DHS surveys. Prior validation of the questionnaires used for data collection is extremely important in the generation of high-quality data.

Appropriate criteria for identification of near-miss maternal morbidity in tertiary care facilities: a cross sectional study

Background

The study of severe maternal morbidity survivors (near miss) may be an alternative or a complement to the study of maternal death events as a health care indicator. However, there is still controversy regarding the criteria for identification of near-miss maternal morbidity. This study aimed to characterize the near miss maternal morbidity according to different sets of criteria.

Methods

A descriptive study in a tertiary center including 2,929 women who delivered there between July 2003 and June 2004. Possible cases of near miss were daily screened by checking different sets of criteria proposed elsewhere. The main outcome measures were: rate of near miss and its primary determinant factors, criteria for its identification, total hospital stay, ICU stay, and number and kind of special procedures performed.

Results

There were two maternal deaths and 124 cases of near miss were identified, with 102 of them admitted to the ICU (80.9%). Among the 126 special procedures performed, the most frequent were central venous access, echocardiography and invasive mechanical ventilation. The mean hospital stay was 10.3 (± 13.24) days. Hospital stay and the number of special procedures performed were significantly higher when the organ dysfunction based criteria were applied.

Conclusion

The adoption of a two level screening strategy may lead to the development of a consistent severe maternal morbidity surveillance system but further research is needed before worldwide near miss criteria can be assumed.

A prova de trabalho e a via de parto em primíparas com uma cesárea anterior

OBJECTIVE

To identify factors associated with cesarean section in women with only one previous delivery by cesarean section and undergoing a trial of labor.

METHODS

A retrospective cross sectional study was performed from 1986 to 1998 including a total of 1746 women with one prior cesarean section and delivering after a trial of labor. Cases with a current twin pregnancy or with malformation incompatible with life were excluded. Women were divided in two groups according to the mode of the second delivery: Cesarean (n=731) or Vaginal Birth After Cesarean (VBAC, n=1015). To identify factors associated to the mode of delivery, the prevalence ratios (PR) and the 95%CI for each isolated factor, adjusted according to age, were assessed. In each analysis, cases with missing information were excluded.

RESULTS

The total rate of Vaginal Birth After Cesarean was 58.1%. The factors significantly associated with cesarean section were: higher maternal age, greater fundal height (PR 1.5; 95%CI 1.19-1.88), premature rupture of membranes (1.3; 1.08-1.54), amniotic fluid with an altered aspect (1.22; 1.04-1.43) or volume (1.32; 1.01-1.73), altered fetal heart rate (1.96; 1.68-2.28), non cephalic presentation (2.03; 1.54-2.66), induction of labor (1.74; 1.42-2.11) and no labor analgesia (2.57; 2.11-3.11).

CONCLUSION

The factors associated with cesarean section were older age, non-cephalic presentation, premature rupture of membranes, signs of large fetus, the need of induction of labor and signs of compromised fetal wellbeing.

Systemic lupus erythematosus and pregnancy: clinical evolution, maternal and perinatal outcomes and placental findings

CONTEXT AND OBJECTIVE

Systemic lupus erythematosus is a chronic disease that is more frequent in women of reproductive age. The relationship between lupus and pregnancy is problematic: maternal and fetal outcomes are worse than in the general population, and the management of flare-ups is difficult during this period. The aim here was to compare the outcomes of 76 pregnancies in 67 women with lupus, according to the occurrence or absence of flare-ups.

DESIGN AND SETTING

An observational cohort clinical study evaluating the evolution of pregnant women with lupus who were receiving care at the prenatal outpatient clinic, Centro de Atenção Integral à Saúde da Mulher, Universidade Estadual de Campinas (CAISM/Unicamp), between 1995 and 2002.

METHODS

Data were collected on a precoded form. The women were divided into two groups according to the occurrence or absence of flare-ups, as defined by the systemic lupus erythematosus disease activity index (SLEDAI). The presence or absence of flare-ups and renal involvement was considered to be the independent variable and the other results were dependent variables.

RESULTS

Flare-ups occurred in 85.3% of cases, and were most significant when there was renal involvement. This was related to greater numbers of women with preeclampsia and poor perinatal outcome. Intrauterine growth restriction was more common in the women with active disease. Placental weight was significantly lower in the women with renal involvement.

CONCLUSIONS

Flare-ups and renal involvement in lupus patients during pregnancy are associated with increased maternal and perinatal complications.

[Support during childbirth: perception of health care providers and companions chosen by women]

OBJECTIVE

To understand health care providers' perception on managing laboring women in the presence of a labor companion of their choice, and the labor companion's perception of this experience.

METHODS

A qualitative study was conducted based on a controlled randomized clinical trial. Sampling was intentional and determined through information saturation. Semi-structured interviews were carried out with 11 health care providers and 16 laboring companions in the obstetric unit of a maternity facility at the hospital complex, in Campinas, Southern Brazil, between October 2004 and March 2005. The thematic analysis of discourse was applied using the following methodological figures: central idea, key expressions and discourse of the collective subject.

RESULTS

The most remarkable central ideas of health care providers were: no difference was observed in managing laboring women with a labor companion; positive changes were noted in labor management when a labor companion was present; the companion provided emotional support to laboring women who were more pleased, and felt safer and peaceful; many positive aspects were seen in the behavior and involvement of laboring women with a labor companion; the companion caused no problems and encouraged health providers to engage in a more humane and less routine attitude. The main central ideas of labor companions were: positive feelings, emotions, a sense of satisfaction with the experience; being with the laboring woman was a great opportunity to provide her emotional support; and they felt welcome by health care providers.

CONCLUSIONS

Health providers considered positive the support provided by a labor companion and had no problems in managing laboring women in the presence of their companions. Labor companions were pleased and happy with this experience. There was no conflicting opinions.

Apoio no nascimento: percepções de profissionais e acompanhantes escolhidos pela mulher

OBJETIVO: Descrever a percepção de profissionais da saúde sobre prestar assistência à parturiente na presença do acompanhante por ela escolhido, e a percepção dos acompanhantes sobre essa experiência. MÉTODOS: Realizou-se estudo qualitativo, a partir de ensaio clínico randomizado controlado. A amostra estudada foi intencional e definida por saturação de informação. Foram entrevistados 11 profissionais da saúde e 16 acompanhantes no centro obstétrico de uma maternidade em Campinas, SP, de outubro de 2004 a março de 2005. Empregou-se a técnica de análise temática de discurso, utilizando-se as figuras metodológicas: idéia central, expressões-chave e o discurso do sujeito coletivo. RESULTADOS: Entre as idéias centrais dos profissionais destacaram-se: não houve diferença em prestar assistência com acompanhante durante o trabalho de parto e parto; com o acompanhante ocorreram mudanças positivas na assistência; o acompanhante dá apoio emocional à parturiente, que fica mais satisfeita, segura e tranqüila; existem muitos aspectos positivos no comportamento e participação das parturientes com acompanhante; o acompanhante não causou problema e fez o profissional ter atitude mais humana e menos rotineira. As principais idéias centrais dos acompanhantes foram: sentimentos positivos, emoção, satisfação com a experiência; poder ajudar ao dar apoio emocional; sentir-se bem recebido pelos profissionais. CONCLUSÕES: Os profissionais da saúde consideraram importante o apoio do acompanhante não tendo sido observado problema em prestar assistência na sua presença. Os acompanhantes se sentiram satisfeitos e recompensados com a experiência. Não foram detectados conflitos de opinião entre os envolvidos.

Revisão sistemática sobre morbidade materna near miss

Esta revisão sistemática sobre near miss materna objetivou analisar dados de incidência e as definições adotadas de near miss. Procedeu-se uma busca eletrônica em bancos de periódicos científicos e também das referências bibliográficas dos estudos identificados. Foram identificados inicialmente 1.247 estudos, analisados na íntegra 35, sendo 17 excluídos e 18 incluídos. A revisão da lista de referências destes artigos identificou mais vinte, totalizando assim 38 estudos incluídos: vinte com definições de near miss relacionadas à complexidade do manejo, seis de disfunção orgânica, dois com definição mista e dez pela presença de sinais ou entidades clínicas específicas. A razão de near miss média foi de 8,2/mil partos, o índice de mortalidade materna foi 6,3% e a razão caso:fatalidade de 16:1. Conclui-se que a incidência de near miss tende a ser maior nos países em desenvolvimento e quando utilizada a definição de disfunção orgânica. O estudo da morbidade materna near miss pode contribuir para a melhora da atenção obstétrica e subsidiar o combate à morte materna.

[Evidence on support during labor and delivery: a literature review]

The effects of support for women during labor and delivery provided by health professionals, lay women, and doulas on the maternal and neonatal outcomes have been evaluated through randomized clinical trials, meta-analyses, and systematic reviews. This article presents a review of these studies, focusing on the principal characteristics, support provider, simultaneous presence of the woman's spouse and/or family members during labor and delivery and the outcomes. The analysis included studies published from 1980 to 2004 which explicitly approached these aspects. In general, the results of such support were favorable, highlighting a reduction in the cesarean rate, analgesia/ medication for pain relief, duration of labor, and utilization of oxytocin and an increase in maternal satisfaction with the experience. The benefits were greater when the support provider was not a health professional. The available studies did not evaluate the specific companion chosen by the woman as a support provider, which constitutes a gap in the knowledge that should be filled by future research.

Misoprostol versus expectant management in premature rupture of membranes at term

OBJECTIVE

To compare the effectiveness of immediate induction of labour with vaginal misoprostol versus expectant management for 24 hours followed by oxytocin induction in women with premature rupture of membranes at term (term PROM).

DESIGN

An open, randomised, controlled trial.

SETTING

Public university hospital in Campinas City, Brazil.

POPULATION

One hundred and fifty pregnancies, half of them allocated to each group.

METHODS

Statistical analysis used Student's t test, the chi2 test, Fisher's exact test, survival analysis and risk ratio estimates with 95% CI.

MAIN OUTCOME MEASURES

Latency period, recruitment to delivery period, period of hospitalisation, mode of delivery, contractility pattern, fetal wellbeing, labour and delivery complications, neonatal and maternal morbidity.

RESULTS

Both groups had similar general characteristics, but the misoprostol group had a significantly shorter latency period (9.4 vs 15.8 hours), a shorter time interval from recruitment to delivery (18.9 vs 27.5 hours), a shorter period of maternal hospitalisation and a slightly higher proportion of alterations of contractility when compared with the expectant group. Caesarean section rates were 20% in the misoprostol group and 30.7% in the other. There were no differences between them regarding fetal wellbeing, complications during labour and delivery and neonatal or postpartum maternal morbidity. Within 24 hours, 44% of women had delivered in the expectant group against 73.3% in the misoprostol group.

CONCLUSIONS

Immediate labour induction with misoprostol in cases of term PROM shortens the latency period, the total time between recruitment to delivery and the time of maternal hospitalisation, increasing the occurrence of alterations of contractility without any maternal and perinatal outcomes disadvantages.

Hyaluronidase versus Foley catheter for cervical ripening in high-risk term and post term pregnancies

OBJECTIVE

To evaluate the effectiveness and safety of Foley catheter and hyaluronidase for cervical ripening.

METHOD

Randomized controlled trial where 140 pregnant women, with gestational age > or = 37 weeks, indication for labor induction and an unripe cervix, were enrolled, allocated in two groups according to the method of cervical ripening before labor induction. Statistical analysis used Student's t-test, Mann-Whitney, Chi-square test, survival analysis, risk ratios and number needed to treat.

RESULTS

Time of induction, dose of oxytocin and mode of delivery had better results in the Foley catheter group. Comfort with the method was higher in the hyaluronidase group.

CONCLUSIONS

Both methods were effective and safe for cervical ripening. The Foley catheter group experienced a shorter period of induction, required a lower dose of oxytocin and had higher vaginal delivery rates, while the women who used hyaluronidase declared greater comfort with the method.
