Increased Survival Concomitant with Unchanged Morbidity and Cognitive Disability among Infants Born at the Limit of Viability before 24 Gestational Weeks in 2009-2019.

INTRODUCTION: The aim was to determine risk factors among mothers and outcomes for their children born at the limit of viability in 2009-2019, before and after the introduction of extended interventionist guidelines. METHODS: A retrospective cohort study of births at 22 + 0-23 + 6 gestational weeks in a Swedish Region in 2009-2015 (n = 119), as compared to 2016-2019 (n = 86) after the introduction of new national interventionist guidelines. Infant mortality, morbidity, and cognitive functions at 2 years corrected age according to the Bayley-III Screening Test were monitored. RESULTS: Maternal risk factors for extreme preterm birth were identified. The intrauterine fetal death rates were comparable. Among births at 22 weeks, the neonatal mortality tended to decrease (96 vs. 76% of live births (p = 0.05)), and the 2-year survival tended to increase (4 vs. 24% (p = 0.05)). Among births at 23 weeks, the neonatal mortality decreased (56 vs. 27% of live births (p = 0.01)), and the 2-year survival increased (42 vs. 64% (p = 0.03)). Somatic morbidity and cognitive disability at 2 years corrected age were unchanged. CONCLUSION: We identified maternal risk factors that emphasize the need for standardized follow-up and counseling for women at increased risk of preterm birth at the limit of viability. The increased infant survival concomitant with unchanged morbidity and cognitive disability highlight the importance of ethical considerations regarding interventionist approaches at threatening preterm birth before 24 weeks.

The (mis)use of fetal viability as the determinant of non-criminal abortion in the Netherlands and England and Wales.

Time plays a fundamental role in abortion regulation. In this article, we compare the regulatory frameworks in England and Wales and the Netherlands as examples of the centrality accorded to viability in the determination of the parameters of non-criminal abortion, demonstrating that the use of viability as a threshold renders the law uncertain. We assess the role played by the concept of viability, analysing its impact upon the continued criminalization of abortion and categorization of abortion as a medical matter, rather than a reproductive choice. We conclude that viability is misconceived in its application to abortion and that neonatal viability (relating to treatment of the premature infant) and fetal viability (related to the capacity to survive birth) must be distinguished to better reflect the social context within which the law and practice of abortion operate. We show how viability thresholds endanger pregnant people.

Melatonin administration during the first half of pregnancy improves the reproductive performance of rabbits: Emphasis on ovarian and placental functions.

This study was designed to investigate the roles of melatonin administration during different sensitive windows of the first half of pregnancy in the function and gene expression of the ovary and placenta, hormone profile, and pregnancy outcomes in rabbits. Four equal experimental groups of 20 rabbits each were used. The first (FW), second (SW), and third (F + SW) groups comprised rabbits that orally received 0.7-mg melatonin/kg body weight during the first week, second weeks, and during both weeks of pregnancy; and the fourth group served as the control group (C). The total number of visible follicles significantly increased in all melatonin-treated groups compared with that in the C group. In all melatonin-treated groups, the number of absorbed fetuses was significantly reduced, whereas the weights of embryonic sacs and fetuses were higher than in the C group. The placenta efficiency was significantly increased in the F + SW group compared with that in the C group, followed by the SW group, whereas no significant difference in the placenta efficiency was found between the FW and C groups. Melatonin treatments significantly improved the expression of antioxidants, gonadotropin receptors, and cell cycle regulatory genes in the ovary, whereas only FW treatment upregulated steroidogenic acute regulatory gene. Compared with the C and FW groups, melatonin treatments during the SW and F + SW significantly upregulated the expression of most genes in the placenta. The concentrations of estradiol were significantly higher in the SW and F + SW groups than in the FW and C groups. The concentrations of progesterone were significantly increased in the FW group compared with those in the C and SW groups, whereas the F + SW group showed intermediate values. The litter size and weight at birth significantly increased in all melatonin-treated groups compared with those in the C group. The second week of pregnancy seems to be a sensitive window for melatonin actions during pregnancy. Thus, melatonin administration during the second week of pregnancy can be effective in improving pregnancy outcomes in rabbits.

Pregnancy outcomes after preterm premature rupture of membranes: The Japan Environment and Children's Study.

AIM: To evaluate the pregnancy outcomes of preterm premature rupture of membranes (preterm PROM; PPROM) by gestational age. METHODS: This cohort study analyzed data from the Japan Environment and Children's Study. Pregnancy outcomes were documented using descriptive statistics. Logistic regression was used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of complications. RESULTS: Data were collected for 104 062 fetuses, and 99 776 were eligible for inclusion. The incidences of early (18-23 weeks) and late (24-36 weeks) PPROM were 0.1% (n = 102) and 1.2% (n = 1205), respectively. Of the 1307 cases, 66 (5.0%) resulted in miscarriage or stillbirth. Overall, 85.6% (1119/1307) resulted in preterm births, and 9.3% (122/1307) in term births. There was a higher incidence of oligohydramnios (OR 6.82, 95% CI 4.07, 11.4; OR 2.42, 95% CI 1.72, 3.40), intrauterine infection (OR 11.9, 95% CI 7.06, 19.9; OR 4.39, 95% CI 3.01, 6.41), cesarean delivery (OR 3.31, 95% CI 2.32, 4.71; OR 1.34, 95% CI 0.97, 1.85), placental abruption (OR 5.57, 95% CI 2.30, 13.5; OR 5.40, 95% CI 3.58, 8.14), and 5-min Apgar score <7 (OR 35.3, 95% CI 21.5, 57.9; OR 2.66, 95% CI 1.75, 4.05) for early and late, compared to no, PPROM, respectively. Miscarriage or stillbirth was higher in early (OR 5.84, 95% CI 3.72, 9.15) and lower in late (OR 0.21, 95% CI 0.06, 0.68) compared to those without PPROM. CONCLUSIONS: This study described the epidemiology of pregnancy outcomes of early (occurring at the limit of viability) and late PPROM.

Case report and literature review of management of preterm prelabour rupture of membranes before fetal viability.

Preterm prelabour rupture of membranes (PPROM) complicates up to 3% of pregnancy and is responsible for one third of preterm deliveries. PPROM at extremely preterm gestations (<24 weeks) affects 0.4% of pregnancies and is associated with low neonatal survival rates, high rate of neonatal complications in survivors, and carries major risk of maternal morbidity and mortality. We present a rare case of pregnancy complicated by PPROM at 14 weeks which resulted in a term delivery and a good neonatal outcome.

Defining Preterm Birth and Stillbirth in the Western Pacific: A Systematic Review.

Preterm birth and stillbirth are important global perinatal health indicators. Definitions of these indicators can differ between countries, affecting comparability of preterm birth and stillbirth rates across countries. This study aimed to document national-level adherence to World Health Organization (WHO) definitions of preterm birth and stillbirth in the WHO Western Pacific region. A systematic search of government health websites and 4 electronic databases was conducted. Any official report or published study describing the national definition of preterm birth or stillbirth published between 2000 and 2020 was eligible for inclusion. A total of 58 data sources from 21 countries were identified. There was considerable variation in how preterm birth and stillbirth was defined across the region. The most frequently used lower gestational age threshold for viability of preterm birth was 28 weeks gestation (range 20-28 weeks), and stillbirth was most frequently classified from 20 weeks gestation (range 12-28 weeks). High-income countries more frequently used earlier gestational ages for preterm birth and stillbirth compared with low- to middle-income countries. The findings highlight the importance of clear, standardized, internationally comparable definitions for perinatal indicators. Further research is needed to determine the impact on regional preterm birth and stillbirth rates.

Premature rupture of the membranes at 16 weeks: report of a successful outcome of pregnancy and review of the literature.

Prelabor rupture of the fetal membranes (premature rupture of membranes, PROM) before or at the limit of fetal viability is condition associated with significant and serious pediatric morbidity and mortality. It is a rare problem, with an estimated incidence between 0.1 and 0.7%. Management of this condition is one of the most challenging clinical situations in obstetrics. We report the case of a pregnant woman presenting at 16 weeks gestation with ruptured membranes. The course of pregnancy was further complicated by complete placenta previa. Expectant management was undertaken, with term delivery and successful outcome of pregnancy. Expectant management is a reasonable approach in properly selected patients. Better understanding of the mechanisms of spontaneous membrane resealing is needed in order to improve poor outcomes. More published data and evidence are necessary to standardize treatment options for this rare condition.

Peaceful End of Life in an Unviable Newborn: A Case Report.

The limit of viability is a period of uncertainty regarding the prognosis and treatment, where palliative care (PC) is important to dignify death, although, in several countries, they are not implemented as in Colombia. The peculiarities of newborns make PC differ from care at other stages of life and which are rarely accepted by professionals who consider them overwhelming. The case of a newborn of 23 weeks of gestation is exposed where nursing care is revealed to the newborn and his family according to the theory of the peaceful end of life (PEL). The theory of the PEL is useful in the development of neonatal PC, which must be differentiated, improving well-being, and family support. Furthermore, health systems must recognize emotional risks for professionals.

[Severely injured pregnant women-The obstetrical perspective!] / Schwer verletzte Schwangere aus Sicht der Geburtshilfe.

The treatment of severely injured pregnant women places the highest demands on interdisciplinary cooperation in order to adequately account for maternal and fetal requirements. In the preclinical stage the mother must be optimally stabilized and treated. Important is the correct left lateral position (15° to relieve the vena cava) during the transfer to the trauma unit. On arrival at the hospital, obstetricians and neonatologists should be involved in the diagnostic and therapeutic measures at an early stage. In principle, all methods that are used in non-pregnant polytrauma patients should also be used without hesitation, especially in the initial routine diagnostics in order to establish the best treatment plan. The question of emergency delivery depends on the gestational age, the acute situation of the fetus and the mother as well as the risks resulting from the next therapeutic steps with respect to monitoring and intervention options in favor of the child.

Impact of ectogenesis on the medicalisation of pregnancy and childbirth.

The medicalisation of pregnancy and childbirth has been encouraged by the continuing growth of technology that can be applied to the reproductive journey. Technology now has the potential to fully separate reproduction from the human body with the prospect of ectogenesis-the gestation of a fetus outside of the human body. This paper considers the issues that have been caused by the general medicalisation of pregnancy and childbirth and the impact that ectogenesis may have on these existing issues. The medicalisation of pregnancy and childbirth is criticised for its impact on the relationship between doctors and pregnant women and the way in which doctors treat fetuses. It is argued that ectogenesis may cause more imbalance in the doctor and intended parent relationship and may result in an increased lack of clarity regarding a doctor's duty to the fetus. This paper finds that extensive guidance and revised legislation will be necessary to minimise the impact of ectogenesis on the existing issues caused by the medicalisation of reproduction.

Clinical and Ultrasound Evaluation of Early Threatened Miscarriage to Predict Pregnancy Continuation up to 28 Weeks: A Prospective Cohort Study.

OBJECTIVES: (1) To study the predictors of pregnancy continuation up to 28 weeks in first-trimester threatened miscarriage after a single clinical and ultrasound (US) evaluation. (2) To assess the role of both clinical and US predictors in counseling and decreasing repeated emergency follow-up scans. METHODS: A prospective observational study that included a cohort of 241 patients with threatened miscarriage (≥6-12 weeks) was conducted. They had a single clinical and US evaluation, and then they were contacted by weekly phone calls until completing 28 weeks' gestation or reporting miscarriage. Independently, all patients were followed by the recommended routine US scanning with or without emergency visits. RESULTS: Two hundred thirty-three patients completed the study, of whom 193 patients continued up to 28 weeks' gestation, and 40 miscarried (17.1%). Only spotting/mild bleeding episodes and progesterone treatment were the clinical predictors of fetal viability. The embryonic/fetal heart rate (E/FHR) was the best single US predictor, with a specificity and positive predictive value of 95.3% and 97.2%, respectively. Combining 3 US parameters, at their best cutoff points (E/FHR >113 beats per minute, crown-rump length >19.9 mm, and gestational sac diameter >27.3 mm), had a specificity and positive predictive value of 98% and 99% (first-trimester US triad of fetal viability). CONCLUSIONS: [1] In first-trimester threatened miscarriage, clinical parameters that could predict fetal viability included spotting/ mild bleeding and progesterone treatment. [2] After a single US scan, the presence of at least an E/FHR of greater than 113 bpm or the suggested first-trimester US triad appeared as a simple, measurable, and effective predictor of pregnancy continuation up to 28 weeks. [3] These US predictors are not to replace the recommended scheduled scanning during pregnancy. [4] This can improve patients' counseling and decrease the need for repeated emergency follow-up scans. Otherwise, there is an indication for repeating US scans at a 1-week to 10-day interval.

Perinatal care provided for babies born at 23 and 24 weeks of gestation.

In recent years, significant improvements in survival and survival-free of major morbidity in babies born at 23+0 to 24+6  weeks of gestation have led to a more pro-active approach to resuscitation at these peri-viable gestations. Antenatal counselling and interventions, intrapartum care and postnatal advice should be part of the package of care provided to optimise outcomes for these babies and their families. This observational study assesses the perinatal care provided to mothers and their babies who were born at 23 and 24 weeks of gestations over a two-year period at a tertiary maternity hospital in New Zealand.

Preterm premature rupture of the membranes: Guidelines for clinical practice from the French College of Gynaecologists and Obstetricians (CNGOF).

In France, the frequency of premature rupture of the membranes (PROM) is 2%-3% before 37 weeks' gestation (level of evidence [LE] 2) and less than 1% before 34 weeks (LE2). Preterm delivery and intrauterine infection are the major complications of preterm PROM (PPROM) (LE2). Prolongation of the latency period is beneficial (LE2). Compared with other causes of preterm delivery, PPROM is associated with a clear excess risk of neonatal morbidity and mortality only in cases of intrauterine infection, which is linked to higher rates of in utero fetal death (LE3), early neonatal infection (LE2), and necrotizing enterocolitis (LE2). The diagnosis of PPROM is principally clinical (professional consensus). Tests to detect IGFBP-1 or PAMG-1 are recommended in cases of uncertainty (professional consensus). Hospitalization is recommended for women diagnosed with PPROM (professional consensus). Adequate evidence does not exist to support recommendations for or against initial tocolysis (Grade C). If tocolysis is prescribed, it should not continue longer than 48 h (Grade C). The administration of antenatal corticosteroids is recommended for fetuses with a gestational age less than 34 weeks (Grade A) and magnesium sulfate if delivery is imminent before 32 weeks (Grade A). The prescription of antibiotic prophylaxis at admission is recommended (Grade A) to reduce neonatal and maternal morbidity (LE1). Amoxicillin, third-generation cephalosporins, and erythromycin (professional consensus) can each be used individually or eythromycin and amoxicillin can be combined (professional consensus) for a period of 7 days (Grade C). Nonetheless, it is acceptable to stop antibiotic prophylaxis when the initial vaginal sample is negative (professional consensus). The following are not recommended for antibiotic prophylaxis: amoxicillin-clavulanic acid (professional consensus), aminoglycosides, glycopeptides, first- or second-generation cephalosporins, clindamycin, or metronidazole (professional consensus). Women who are clinically stable after at least 48 h of hospital monitoring can be managed at home (professional consensus). Monitoring should include checking for clinical and laboratory factors suggestive of intrauterine infection (professional consensus). No guidelines can be issued about the frequency of this monitoring (professional consensus). Adequate evidence does not exist to support a recommendation for or against the routine initiation of antibiotic therapy when the monitoring of an asymptomatic woman produces a single isolated positive result (e.g., elevated CRP, or hyperleukocytosis, or a positive vaginal sample) (professional consensus). In cases of intrauterine infection, the immediate intravenous administration (Grade B) of antibiotic therapy combining a beta-lactam with an aminoglycoside (Grade B) and early delivery of the child are both recommended (Grade A). Cesarean delivery of women with intrauterine infections is reserved for the standard obstetric indications (professional consensus). Expectant management is recommended for uncomplicated PROM before 37 weeks (Grade A), even when a sample is positive for Streptococcus B, as long as antibiotic prophylaxis begins at admission (professional consensus). Oxytocin and prostaglandins are two possible options for the induction of labor in women with PPROM (professional consensus).

[Antenatal management in case of preterm premature rupture of membranes before fetal viability: CNGOF Preterm Premature Rupture of Membranes Guidelines]. / Prise en charge anténatale en cas de rupture prématurée des membranes avant la viabilité fœtale. RPC Rupture prématurée des membranes avant terme CNGOF.

OBJECTIVES: To evaluate the maternal, perinatal and long-term prognosis in the event of previable premature rupture of the membranes (PROM) and to specify the interventions likely to reduce the risks and improve the prognosis. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Previable PROM is a rare event whose frequency varies from 0.3 to 1% according to estimates (NP4). When occurring as a complication of amniocentesis, the prognosis is generally better than when spontaneous (NP3). Between 23 and 39% of women will deliver in the week following PROM and nearly 40% of women will not have given birth 2 weeks after (NP3). The frequency of medical termination of pregnancy varies greatly according to the studies (NP4), as does that of fetal death (NP4). Hospital survival and survival rates without major morbidity as a proportion of conservatively treated patients range from 17-55% and 26-63%, respectively (NP4). Neonatal prognosis is largely dominated by prematurity and its complications (NP3). The frequency of maternal sepsis varies from 0.8 to 4.8% in the most recent studies (NP4). Only one case of maternal death is reported, although 3 cases were identified in France between 2007 and 2012 (NP3). Information is a major component of the care to be provided to women and their partners (Professional consensus). An initial period of hospitalization may be proposed after previable PROM (Professional consensus). Thereafter, there is no argument to recommend hospital management rather than extra-hospital management when there is no argument in favour of intrauterine infection (Professional consensus). An evaluation of the amount of amniotic fluid by ultrasound may be proposed at the initial consultation and after a period of 7 to 14 days if pregnancy continues (Professional consensus). Prophylactic antibiotic treatment is recommended as soon as PROM is diagnosed (Professional consensus). The gestational age at which corticosteroid therapy may be proposed will depend on the thresholds selected for neonatal resuscitation care. In particular, it will take into account parental positioning (Professional consensus). From the time of the decision to perform neonatal resuscitation until the gestational age of 32 weeks, it is recommended to administer MgSO4 to the woman whose delivery is imminent (Grade A). Tocolysis is not recommended in this context (Professional consensus). In certain situations, meeting strictly the conditions mentioned by the CSP article L. 2213-1, a maternal request for medical interruption of pregnancy may be discussed. CONCLUSION: The levels of evidence of scientific work on the management of previable PROM are low, therefore, most of the recommendations proposed here are based on professional agreement by "reasonable" extension of recommendations valid for later gestational ages.

Opinions of Brazilian resuscitation instructors regarding resuscitation in the delivery room of extremely preterm newborns / Opiniões dos instrutores de reanimação brasileiros quanto à reanimação em sala de parto de em recém-nascidos pré-termo extremos

Abstract Objective: To describe the opinions of pediatricians who teach resuscitation in Brazil on initiating and limiting the delivery room resuscitation of extremely preterm infants. Method: Cross-sectional study with electronic questionnaire (Dec/2011-Sep/2013) sent to pediatricians who are instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics, containing three hypothetical clinical cases: (1) decision to start the delivery room resuscitation; (2) limitation of neonatal intensive care after delivery room resuscitation; (3) limitation of advanced resuscitation in the delivery room. For each case, it was requested that the instructor indicate the best management for each gestational age between 23 and 26 weeks. A descriptive analysis was performed. Results: 560 (82%) instructors agreed to participate. Only 9% of the instructors reported the existence of written guidelines at their hospital regarding limitations of delivery room resuscitation. At 23 weeks, 50% of the instructors would initiate delivery room resuscitation procedures. At 26 weeks, 2% would decide based on birth weight and/or presence of fused eyelids. Among the participants, 38% would re-evaluate their delivery room decision and limit the care for 23-week neonates in the neonatal intensive care unit. As for advanced resuscitation, 45% and 4% of the respondents, at 23 and 26 weeks, respectively, would not apply chest compressions and/or medications. Conclusion: Difficulty can be observed regarding the decision to not resuscitate a preterm infant with 23 weeks of gestational age. At the same time, a small percentage of pediatricians would not resuscitate neonates of unquestionable viability at 26 weeks of gestational age in the delivery room.

Resumo Objetivo: Descrever opiniões dos pediatras que ensinam reanimação no Brasil a respeito de iniciar e limitar a reanimação em sala de parto de neonatos pré-termo extremos. Método: Estudo transversal com questionário eletrônico (dez/11-set/13) enviado aos instrutores do Programa de Reanimação Neonatal da Sociedade Brasileira de Pediatria com três casos clínicos hipotéticos: 1) decisão de iniciar ou não a reanimação; 2) limitação ou não dos cuidados intensivos após a reanimação em sala de parto; 3) limitação ou não da reanimação avançada em sala de parto. Para cada caso foi solicitada a indicação da conduta para cada idade gestacional entre 23-26 semanas. A análise foi descritiva por meio da frequência das respostas. Resultados: Consentiram em participar 560 (82%) instrutores. Apenas 9% afirmaram existir em seu hospital norma escrita sobre quando não iniciar a reanimação em sala de parto. Com 23 semanas, 50% dos instrutores fariam a reanimação em sala de parto e com 26 semanas 2% baseariam sua decisão no peso ao nascer e/ou na abertura da fenda palpebral. Dos entrevistados, 38% reavaliariam sua decisão e limitariam o cuidado na UTI a medidas de conforto para nascidos de 23 semanas reanimados na sala de parto. Quanto aos procedimentos de reanimação avançada, 45% e 4% com 23 e 26 semanas, respectivamente, não indicariam tais manobras. Conclusão: Observa-se dificuldade na opção de não reanimar neonatos com 23 semanas de gestação e, ao mesmo tempo, um pequeno percentual de pediatras não reanima, na sala de parto, neonatos cuja viabilidade não é questionada (26 semanas).

Effects of rapid temperature fluctuations prior to breeding on reproductive efficiency in replacement gilts.

Rapidly cooling pigs after heat stress (HS) results in a pathophysiological condition, and because rapid temperature fluctuations may be associated with reduced reproductive success in sows, it lends itself to the hypothesis that these conditions may be linked. Objectives were to determine the effects of rapid cooling on thermal response and future reproductive success in pigs. Thirty-six replacement gilts (137.8±0.9kg BW) were estrus synchronized and then 14.1±0.4 d after estrus confirmation, pigs were exposed to thermoneutral conditions (TN; n=12; 19.7±0.9°C) for 6h, or HS (36.3±0.5°C) for 3h, followed by 3h of rapid cooling (HSRC; n=12; immediate TN exposure and water dousing) or gradual cooling (HSGC; n=12; gradual decrease to TN conditions) repeated over 2 d. Vaginal (TV) and gastrointestinal tract temperatures (TGI) were obtained every 15min, and blood was collected on d 1 and d 2 during the HS and recovery periods at 180 and 60min, respectively. Pigs were bred 8.3±0.8 d after thermal treatments over 2 d. Reproductive tracts were collected and total fetus number and viability were recorded 28.0±0.8 d after insemination. HS increased TV and TGI (P=0.01; 0.98°C) in HSRC and HSGC compared to TN pigs. During recovery, TV was reduced from 15 to 105min (P=0.01; 0.33°C) in HSRC compared to HSGC pigs, but no overall differences in TGI were detected (P<0.05; 39.67°C). Rapid cooling increased (P<0.05) TNFα compared to HSGC and TN pigs during recovery-d 1 (55.2%), HS-d 2 (35.1%), and recovery-d 2 (64.9%). Viable fetuses tended to be reduced (P=0.08; 10.5%) and moribund fetuses tended to be increased (P=0.09; 159.3%) in HSRC compared to HSGC and TN pigs. In summary, rapid cooling prior to breeding may contribute to reduced fetal viability and reproductive success in pigs.

Association of gestational age with the option of pregnancy termination for fetal abnormalities incompatible with neonatal survival / Associação da idade gestacional com a opção pela interrupção da gravidez de fetos com anomalias incompatíveis com a sobrevida neonatal

ABSTRACT Objective: To identify the profile of women seen in a Fetal Medicine unit, diagnosed with fetal abnormality incompatible with neonatal survival in their current pregnancy, and to check the association of gestational age upon diagnosis with the option of pregnancy termination. Methods: This is a retrospective cohort study carried out in the Fetal Medicine Outpatients Clinic of a university hospital, in the city of São Paulo (SP), Brazil, using medical records of pregnant women with fetus presenting abnormalities incompatible with neonatal survival. The sample comprised 94 medical records. The Statistical Package for the Social Sciences (SPSS), version 19, was used for the data statistical analysis. Results: The population of the study included young adult women, who had complete or incomplete high school education, employed, with family income of one to three minimum wages, single, nonsmokers, who did not drink alcoholic beverages or used illicit drugs. Women with more advanced gestational age upon fetal diagnosis (p=0.0066) and/or upon admission to the specialized unit (p=0.0018) presented a lower percentage of termination of pregnancy. Conclusion: Due to characteristics different from those classically considered as of high gestational risk, these women might not be easily identified during the classification of gestational risk, what may contribute to a late diagnosis of fetal diseases. Early diagnosis enables access to specialized multiprofessional care in the proper time for couple's counseling on the possibility of requesting legal authorization for pregnancy termination.

RESUMO Objetivo: Identificar o perfil de mulheres atendidas em um serviço de Medicina Fetal, que receberam diagnóstico de anomalia fetal incompatível com a sobrevida neonatal na gestação atual, e verificar a associação da idade gestacional no diagnóstico com a opção pela interrupção da gravidez. Métodos: Trata-se de um estudo de coorte retrospectivo, realizado no ambulatório de Medicina Fetal de um hospital universitário da cidade de São Paulo (SP), com prontuários de mulheres com fetos portadores de anomalias incompatíveis com a sobrevida neonatal na gestação atual. A amostra constituiu-se de 94 prontuários. Para análise estatística dos dados, utilizou-se o programa Statistical Package for the Social Sciences (SPSS), versão 19. Resultados: A população foi de mulheres adultas jovens, com escolaridade compatível com o Ensino Médio completo/incompleto, empregadas, com renda familiar entre um e três salários mínimo, solteiras, que não faziam uso de tabaco, bebidas alcoólicas ou de drogas ilícitas. Verificou-se que mulheres com maior idade gestacional na ocasião do diagnóstico fetal (p=0,0066) e/ou na chegada ao serviço especializado (p=0,0018) apresentaram menor percentual de interrupção gestacional. Conclusão: Por apresentarem características diferentes daquelas classicamente consideradas de alto risco gestacional, é possível que essas mulheres não tenham sido facilmente identificadas durante a classificação de risco gestacional, o que pode ter colaborado para o diagnóstico tardio de patologias fetais. O diagnóstico precoce possibilita acesso à assistência multiprofissional especializada em tempo adequado para aconselhamento do casal sobre a possibilidade de solicitação de autorização judicial para a interrupção gestacional.
