Diabetes among women with preterm births: outcomes of a Brazilian multicenter study.

OBJECTIVE: The objective was to compare the maternal and perinatal characteristics and outcomes between women with and without diabetes in a Brazilian cohort of women with preterm births. METHODS: This was an ancillary analysis of the Brazilian Multicenter Study on Preterm Birth, which included 4,150 preterm births. This analysis divided preterm births into two groups according to the presence of diabetes; pregestational and gestational diabetes were clustered in the same Diabetes Group. Differences between both groups were assessed using χ 2 or Student's t tests. RESULTS: Preterm births of 133 and 4,017 women with and without diabetes, respectively, were included. The prevalence of diabetes was 3.2%. Pregnant women aged ≥35 years were more common in the Diabetes Group (31.6% versus 14.0% non-diabetic women, respectively). The rate of cesarean section among patients with diabetes was 68.2% versus 52.3% in non-diabetic cases), with a gestational age at birth between 34 and 36 weeks in 78.9% of the cases and 62.1% of the controls. Large-for-gestational-age babies were 7 times more common in the Diabetes Group. CONCLUSION: Preterm birth among Brazilian women with diabetes was more than twice as prevalent; these women were older and had regular late preterm deliveries, usually by cesarean section. They also had a greater frequency of fetal morbidities, such as malformations and polyhydramnios, and a higher proportion of large-for-gestational-age and macrosomic neonates.

Preterm births prevalence during the COVID-19 pandemic in Brazil: results from the national database.

The SARS-CoV-2 (COVID-19) pandemic impacted the health systems between and within countries, and in the course of the pandemic sexual and reproductive health services were the most disrupted. Findings from high-income settings have reported significant changes in preterm birth prevalence during the pandemic period. To understand the possible effects of the COVID-19 pandemic on preterm birth numbers at the Brazilian national level. We compare the number of preterm deliveries during the COVID-19 pandemic period (2020 and 2021) with previous years. We conducted a population-based cross-sectional study taking the period from January 2017 to December 2021 to account. We use individual-level live births data from the Brazilian Live Birth Information System (SINASC), and we estimate the odds ratio (OR) of preterm deliveries using propensity score weighting analysis in Brazil and its regions. During the study period (from 2017 to 2021), about 2.7 million live births were recorded per year, and the missing value for gestational age at delivery was less than 1.5%. The preterm birth prevalence slightly increased during the COVID-19 pandemic compared to the pre-pandemic period (11.32% in 2021 vs 11.09% in 2019, p-value < 0.0001). After adjusting for sociodemographic variables, the OR of preterm births in Brazil has significantly increased, 4% in 2020 (OR: 1.04 [1.03-1.05] 95% CI, p-value < 0.001), and 2% in 2021(OR: 1.02 [1.01-1.03] 95% CI, p-value < 0.001), compared to 2019. At the regional level, the preterm birth pattern in the South, Southeast and Northeast regions show a similar pattern. The highest odds ratio was observed in the South region (2020 vs 2019, OR: 1.07 [1.05-1.10] 95% CI; 2021 vs 2019, OR: 1.03 [1.01-1.06] 95% CI). However, we also observed a significant reduction in the ORs of preterm births in the northern region during the COVID-19 pandemic (2020 vs 2019, OR: 0.96 [0.94-0.98] 95% CI) and (2021 vs 2019, OR: 0.97 [0.95-0.99] 95% CI). Our analysis shows that the pandemic has increased regional variation in the number of preterm births in Brazil in 2020 and 2021 compared to the pre-pandemic years.

The Use of Mid-Pregnancy Cervical Length to Predict Preterm Birth in Brazilian Asymptomatic Twin Gestations.

OBJECTIVE: To describe a reference curve for cervical length (CL) in mid-trimester twin gestations using transvaginal ultrasound (TVU) and to investigate whether short CL increases spontaneous preterm birth (sPTB) in asymptomatic twin pregnancies. METHODS: This was a prospective cohort study performed at 17 outpatient antenatal facilities of Brazil with women at 18 0/7 to 22 6/7 weeks of gestation who participated in a randomized clinical trial screening phase (P5 trial) between July 2015 and March 2019. TVU was performed to provide CL measurement in all screened women. Almost all women with CL ≤ 30 mm received vaginal progesterone 200mg/day and they were also randomized to receive cervical pessary or not. We considered data from the CL distribution among asymptomatic twin pregnancies and analyzed CL and its association with PTB generating receiver operating characteristics (ROC) curves and Kaplan-Meier curves. RESULTS: A total of 253 pregnant women with twins were included in the distribution curve. The mean CL was 33.7 mm and median was 35.5mm. The 10th percentile was 17.8mm. We identified a PTB rate of 73.9% (187/253) with 33.6% of sPTB < 37 (85/253) and 15% (38/253) of sPTB < 34 weeks. The best cutoff point to predict sPTB < 37 was 24.15 mm. However, the ROC curve showed a poor performance (0.64). The Kaplan-Meier survival curves identified that only CL values ≤ 20mm were associated to sPTB < 34 weeks. CONCLUSION: A cutoff point of CL ≤ 20 mm can be interesting point to identify short cervix in Brazilian twin pregnancies. However, in Brazilian asymptomatic twin pregnancies, CL does not show a good performance to predict PTB.

OBJETIVO: Descrever uma curva de referência da medida do colo uterino no Segundo trimestre de gestações gemelares através de ultrassonografia transvaginal (TVU) e investigar a correlação entre a medida do colo uterino (CL) e o parto prematuro espontâneo (sPTB) em pacientes assintomáticas. MéTODOS: Foi realizado uma coorte prospectiva multicêntrica em 17 centros de referência do Brasil com mulheres com gestação gemelar entre 18 0/7 a 22 6/7 semanas de gestação que participaram da primeira fase de um ensaio clínico randomizado (P5 trial) entre Julho/2015 a Março/2019. TVU foi realizada para obter a medida do colo uterino em todas as mulheres. A maioria das mulheres com CL ≤30 mm receberam progesterona por via vaginal 200mg/dia e estas foram randomizadas para receber ou não um pessário cervical. Este estudo considerou dados da medida do colo uterino entre mulheres assintomáticas, desenvolvendo uma curva de referência para gestantes gemelares e sua capacidade de predição do parto prematuro através de curva ROC (receiver operating characteristics) e curvas de sobrevida de Kaplan-Meyer. RESULTADOS: O total de 253 gestantes foram incluídos no estudo, A média do CL foi 33.7mm e a mediana 35.5mm. O Percentil 10 do CL foi 17.8mm. A taxa de parto prematuro foi de 73.9% (187/253) com 33.6% de sPTB < 37 (85/253) e 15% (38/253) de sPTB < 34 semanas. O melhor ponto de corte para predizer sPTB < 37 foi 24.15 mm, entretanto a curva ROC demonstrou baixa performance (0.64). A curva de Kaplan-Meier para sPTB identificou que apenas CL ≤ 20 mm estavam associados a sPTB < 34 semanas. CONCLUSãO: Colo uterino ≤20 mm pode ser um interessante ponto de corte para identificar colo curto entre gestações gemelares assintomáticas brasileiras. Entretanto, a medida do colo uterino não apresentou boa performance para predizer parto prematuro.

Anesthesia technique and postpartum hemorrhage: a prospective cohort study.

BACKGROUND AND OBJECTIVE: During the past few years, an increased number of postpartum hemorrhages have been noticed, even in high-income countries. It has been suggested that this escalation could be associated with increased obstetric interventions. Among such interventions, anesthesia is one of the most prevalent. The present study aimed to investigate the influence of peripartum anesthesia on total blood loss during the 24 hours after delivery. METHODS: We performed a complementary analysis from a prospective cohort study that evaluated postpartum bleeding within 24 hours after birth. The study was performed between February 1st, 2015 and March 31st, 2016 at the Women's Hospital at the Universidade Estadual de Campinas, Brazil. Postpartum bleeding was measured using a calibrated drape and summing the blood contained in the compresses and pads used for 24 hours. We calculated means, percentages, and standard deviation and performed Mann-Whitney analysis for the relation of anesthesia with Postpartum Hemorrhage (PPH) and logistic regression for drugs used in the anesthesia with PPH, using SAS 9.4 software. RESULTS: We included 270 women in the study; of these, 168 received anesthesia for delivery and almost 50% of them had spinal and epidural anesthesia. The mean blood loss within 24 hours after delivery did not show differences between those who did and those who did not receive obstetrical anesthesia (579.0 ± 361.6 vs. 556.6 ± 360.6; p = 0.57). Logistic regression showed that anesthesia, the type of anesthesia, and the drug used did not influence the PPH above 500 mL and above 1000 mL within 2 hours (p > 0.05). CONCLUSION: Anesthesia did not influence postpartum bleeding after vaginal delivery.

Understanding How Health Providers Identify Women with Postpartum Hemorrhage: A Qualitative Study.

OBJECTIVE: To identify how health providers recognize postpartum hemorrhage early and the difficulties involved in it. METHODS: An exploratory, descriptive study using a qualitative approach through a semi-structured interview technique. In total, 27 health professionals (nursing technicians, nurses, medical residents in Gynecology and Obstetrics, hired medical doctors, and medicine professors) working in a tertiary-level hospital of reference in women's health care in the State of São Paulo, Brazil, participated in the study through an invitation. After they accepted the invitation, they signed the free and informed consent form. All interviews were recorded and transcribed, and a thematic analysis was conducted. We found three analysis categories: a) perception of the severity: "there is something wrong with the women"; b) difficulties in the early diagnosis of postpartum hemorrhage; and c) the process to improve obstetrical care. RESULTS: Caregivers believe teamwork and communication should be improved. Besides the visual estimation of blood loss, the nursing team is attentive to behavioral symptoms like irritability, while the medical staff follow protocols and look for objective signs, such as altered vital signs. CONCLUSION: Besides the objective evaluations, the subjective perceptions of the providers are involved in the clinical judgement regarding the diagnosis of postpartum hemorrhage, and this should be included in a broader diagnosis strategy.

OBJETIVO: Identificar como os profissionais de saúde reconhecem precocemente os casos de hemorragia pós-parto e as suas dificuldades. MéTODOS: Realizou-se um estudo exploratório, descritivo, com uma abordagem qualitativa por meio da técnica de entrevista semiestruturada. Por meio de um convite, participaram do estudo 27 profissionais saúde (técnicas de enfermagem, enfermeiras, residentes de Ginecologia e Obstetrícia, e médicos contratados e docentes) que trabalhavam em um hospital de nível terciário de referência no atendimento à saúde da mulher no estado de São Paulo. Depois que os participantes aceitaram o convite, eles assinaram o termo de consentimento livre e esclarecido. Todas as entrevistas foram gravadas, transcritas, e realizou-se uma análise temática. Identificaram-se três categorias de análise: a) percepção da gravidade: "há algo de errado com as mulheres"; b) dificuldades no diagnóstico precoce da hemorragia pós-parto; e c) o processo para melhorar a atenção em obstetrícia. RESULTADOS: Os profissionais de saúde acreditavam que o trabalho em equipe e a comunicação deviam ser aperfeiçoados. Além da estimativa visual da perda de sangue, a equipe de enfermagem estava atenta a sintomas comportamentais como irritabilidade, ao passo que o pessoal médico seguia protocolos e procurava sinais objetivos, como sinais vitais alterados. CONCLUSãO: Além das avaliações objetivas, as percepções subjetivas dos provedores estão envolvidas no julgamento clínico do diagnóstico de hemorragia pós-parto, e isto deve ser incluído em uma estratégia de diagnóstico mais ampla.

Risk factors for postpartum hemorrhage and its severe forms with blood loss evaluated objectively - a prospective cohort study / Fatores de risco para hemorragia pós-parto e suas formas graves com perda sanguínea avaliada objetivamente - Um estudo de coorte prospectivo

Abstract Objective To identify risk factors related to postpartum hemorrhage (PPH) and severe PPH with blood loss quantified objectively. Methods This is a complementary analysis of a prospective cohort study that included pregnant women delivering vaginally. The total blood loss was obtained through the sum of the volume collected from the drape with the weight of gauzes, compresses and pads used by women within 2 hours. Exploratory data analysis was performed to assess mean, standard deviation (SD), frequency, percentage and percentiles. The risk factors for postpartum bleeding were evaluated using linear and logistic regression. Results We included 270 women. Themean blood loss at 120 minutes was 427.49 mL (±335.57 mL). Thirty-one percent (84 women) bled > 500mL and 8.2% (22 women) bled > 1,000 mL within 2 hours. Episiotomy, longer second stage of labor and forceps delivery were related to blood loss > 500mL within 2 hours, in the univariate analysis. In the multivariate analysis, only forceps remained associated with bleeding > 500 mL within 2 hours (odds ratio [OR] = 9.5 [2.85-31.53]). Previous anemia and episiotomy were also related to blood loss > 1,000mL. Conclusion Prolonged second stage of labor, forceps and episiotomy are related to increased incidence of PPH, and should be used as an alert for the delivery assistants for early recognition and prompt treatment for PPH.

Use of Intensive Care Unit in Women with Severe Maternal Morbidity and Maternal Death: Results from a National Multicenter Study.

OBJECTIVE: To assess the use of the intensive care unit (ICU) and its effect on maternal mortality (MM) among women with severe maternal morbidity (SMM). MATERIALS AND METHODS: A secondary analysis of a cross-sectional study on surveillance of SMM in 27 Brazilian obstetric referral centers. The analysis focused on the association between ICU use and maternal death according to individual characteristics and disease severity. Two multivariate regressions considering use of the ICU, age, ethnicity, adequacy of care and the human development index were performed to identify the factors associated to maternal death and maternal near-miss. RESULTS: Out of 82,388 deliveries during the period, there were 9,555 (11.6%) women with SMM, and the MM ratio was of 170.4/100 thousand live births. In total, 8,135 (85.1%) patients were managed in facilities in which ICUs were available; however, only 2,059 (25.3%) had been admitted to the ICU. On the multivariate analysis, when the severity of the maternal disease was measured by the maternal severity score (MMS), the strength of the association between the use of the ICU and maternal death was greatly reduced, along with inadequate care and non-availability of the ICU at the facility. On the assessment of only the more critical cases (SMO, severe maternal outcome), the same pattern of association between ICU and MM was observed. In the models used, only inadequate care and MSS were significantly associated with MM. CONCLUSION: The current study indicates that the main variables associated with maternal death are the severity and adequacy of the case management, which is more frequent in ICU admissions. The use of the ICU without the stratification of the patients by severity may not produce the expected benefits for part of the women.

OBJETIVO: Avaliar o efeito da utilização de unidades de terapia intensiva (UTIs) na mortalidade materna (MM) entre mulheres com morbidade materna grave (MMG). MATERIAIS E MéTODOS: Foi realizada uma análise secundária de um estudo transversal de vigilância de morbidade materna grave em 27 centros de referência obstétrica no Brasil. O foco desta análise foi a associação entre a utilização de UTI e morte materna segundo características individuais e condições de gravidade. Análises múltiplas considerando as variáveis uso de UTI, idade, etnia, adequação do cuidado e índice de desenvolvimento humano foram realizadas para identificar os fatores associados à morte materna e near-miss materno. RESULTADOS: Dos 82.388 partos ocorridos durante o período de estudo, 9.555 (11,6%) mulheres apresentaram MMG, e a razão de MM foi de 170,4/100 mil nascidos vivos. Neste grupo, 8.135 (85,1%) pacientes foram atendidas em instituições com disponibilidade de leitos de UTI, mas apenas 2.059 (25,3%) foram de fato admitidas em leitos de UTI. Na análise de regressão multivariada, quando se considerou a gravidade do caso pelo maternal severity score (pontuação de severidade materna, MMS, na sigla em inglês), houve uma grande redução da força de associação entre utilização de UTI e morte materna, além da inadequação do cuidado e não disponibilidade de UTI na instituição. Na avaliação considerando apenas os casos de maior gravidade (desfecho materno grave, DMG), observou-se o mesmo padrão de associação entre UTI e MM. Nos modelos utilizados, apenas a inadequação do cuidado e o MSS apresentam associação significativa com a MM. CONCLUSãO: O presente estudo aponta que as principais variáveis associadas à morte materna são a gravidade e a adequação do manejo do caso, mais frequentes nas internações em UTI. A utilização dos leitos de UTI sem a estratificação da gravidade da paciente pode não trazer benefícios esperados para uma parte das mulheres.

Results Out of 82,388 deliveries during the period, there were 9,555 (11.6%) women with SMM, and the MM ratio was of 170.4/100 thousand live births. In total, 8,135 (85.1%) patients were managed in facilities in which ICUs were available; however, only 2,059 (25.3%) had been admitted to the ICU. On the multivariate analysis, when the severity of the maternal disease was measured by the maternal severity score (MMS), the strength of the association between the use of the ICU and maternal death was greatly reduced, along with inadequate care and non-availability of the ICU at the facility. On the assessment of only the more critical cases (SMO, severe maternal outcome), the same pattern of association between ICU and MM was observed. In the models used, only inadequate care and MSS were significantly associated with MM. Conclusion The current study indicates that the main variables associated with maternal death are the severity and adequacy of the case management, which is more frequent in ICU admissions. The use of the ICU without the stratification of the patients by severity may not produce the expected benefits for part of the women.

Resumo Objetivo Avaliar o efeito da utilização de unidades de terapia intensiva (UTIs) na mortalidade materna (MM) entre mulheres com morbidade materna grave (MMG). Materiais e Métodos Foi realizada uma análise secundária de um estudo transversal de vigilância de morbidade materna grave em 27 centros de referência obstétrica no Brasil. O foco desta análise foi a associação entre a utilização de UTI e morte materna segundo características individuais e condições de gravidade. Análises múltiplas considerando as variáveis uso de UTI, idade, etnia, adequação do cuidado e índice de desenvolvimento humano foram realizadas para identificar os fatores associados à morte materna e near-miss materno. Resultados Dos 82.388 partos ocorridos durante o período de estudo, 9.555 (11,6%) mulheres apresentaram MMG, e a razão de MM foi de 170,4/100 mil nascidos vivos. Neste grupo, 8.135 (85,1%) pacientes foram atendidas em instituições com disponibilidade de leitos de UTI, mas apenas 2.059 (25,3%) foram de fato admitidas em leitos de UTI. Na análise de regressão multivariada, quando se considerou a gravidade do caso pelo maternal severity score (pontuação de severidade materna, MMS, na sigla em inglês), houve uma grande redução da força de associação entre utilização de UTI e morte materna, além da inadequação do cuidado e não disponibilidade de UTI na instituição. Na avaliação considerando apenas os casos de maior gravidade (desfecho materno grave, DMG), observou-se o mesmo padrão de associação entre UTI e MM. Nos modelos utilizados, apenas a inadequação do cuidado e o MSS apresentam associação significativa com a MM. Conclusão O presente estudo aponta que as principais variáveis associadas à morte materna são a gravidade e a adequação do manejo do caso, mais frequentes nas internações em UTI. A utilização dos leitos de UTI sem a estratificação da gravidade da paciente pode não trazer benefícios esperados para uma parte das mulheres.

Assessing and managing hypovolemic shock in puerperal women.

The major cause of maternal death worldwide is postpartum hemorrhage (PPH). Early identification is the basis for adequate treatment. In addition to the visual estimation of blood loss, clinical signs could offer a more reliable representation of the cardiovascular system of the bleeding woman. However, in postpartum women, recognition of hypovolemic shock through vital signs is impaired owing to physiological cardiovascular changes in pregnancy. The Shock Index [SI] is one composite vital sign that may help in the identification of women with hypovolemic shock. Values of SI ≥ 1 in the first hour postpartum indicate cardiac decompensation, and treatment should be implemented immediately. From the diagnosis of PPH, first-line measures should ensure coordinated care actions including the availability of blood derivatives, the establishment of conditions for volume replacement, oxygen therapy, and identification and timely treatment causes of bleeding. Individualized fluid resuscitation should start with warmed crystalloids and be limited to 3.5 L.

Shock index and heart rate standard reference values in the immediate postpartum period: A cohort study.

OBJECTIVE: To determine Shock Index (SI) reference values in the first two hours of the postpartum period after objectively measuring postpartum bleeding. MATERIALS AND METHODS: A complementary analysis using data from a prospective cohort study at Women's Hospital of the University of Campinas, Brazil, between 1 February 2015 and 31 March 2016. It included women giving birth vaginally unless they had one of these conditions: gestational age below 34 weeks, hypertension, hypo- or hyperthyroidism without treatment, any cardiac disease, infections with fever or sepsis, history of coagulopathy or delivery by C-section. Blood loss was measured by adding the blood volume collected in the drape placed under the women's buttocks and the weight of gauzes and compresses used (excluding the dry weight). Vital signs were measured every 5-15 min after delivery. Exploratory data analysis was performed to assess the mean, standard deviation, median, and percentiles (5th, 10th, 25th, 50th, 75th, 90th, 95th). To identify variation among the periods after delivery, the mean SI and heart rate (HR) values observed for the following intervals were used in the analysis: 0-20 min, 21-40 min, 41-60 min, 61-90 min and 91-120 min. RESULTS: One hundred eighty-six women were included. The mean age ± SD was 24.9 ± 6.1 years and the mean gestational age at birth was 39.2 ± 1.8 weeks. At the puerperal period, the mean SI values ranged from 0.68 ± 0.14 to 0.74 ± 0.15. The percentile distribution ranged from 0.46 (5th percentile) to 1.05 (95th percentile). The mean HR values ranged from 80.8 ± 12.7 bpm to 92.3 ± 14.4 bpm. The percentile distribution ranged from 62.0 bpm (5th percentile) to 117 bpm (95th percentile). CONCLUSION: Reference ranges were established for SI and HR values which showed small variations throughout the postpartum period.

Drug use during pregnancy and its consequences: A nested case control study on severe maternal morbidity / Uso de drogas na gestação e suas consequências: um estudo de caso-controle aninhado sobre morbidade materna grave

Abstract 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 thosewith low-risk pregnancy,without SMMand 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, 2nd 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.

Resumo Objetivo Avaliar a relação entre o uso de substâncias psicoativas na gestação e a ocorrência de morbidade materna grave (MMG), resultados perinatais e repercussões no desenvolvimento neuropsicomotor das crianças expostas. Métodos Estudo de caso-controle a partir de uma coorte de morbidade materna grave (COMMAG). Mulheres com MMG foram consideradas casos. Controles foram mulheres com gestação de baixo risco, admitidas no mesmo período que os casos. Os dados da coorte foram coletados retrospectivamente em prontuários de internação para o parto e entrevistas presenciais conduzidas com 638 mulheres e seus filhos da gestação-índice, entre 6 meses e 5 anos após o parto. Na entrevista, o uso de substâncias na gestação foi avaliado com uma pergunta modificada introduzida no questionário para triagem do uso de álcool, tabaco e outras substâncias 2.0 (ASSIST, na sigla em inglês) e o desenvolvimento neuropsicomotor das crianças foi avaliado pelo teste de triagem do desenvolvimento Denver II. Resultados A prevalência do uso de drogas lícitas ou ilícitas na gestação foi de cerca de 17%. Das usuárias, 63,9% usaram álcool, 58,3% usaram tabaco, 9,2% usaram cocaína/crack e 4,6% usaram maconha. Não houve associação entre o uso de drogas na gestação eMMG. Contudo, o uso de tabaco foi associado a hemorragia, presença de critérios clínicos de near miss e alteração no desenvolvimento infantil. O uso de álcool foi associado à asfixia neonatal e o uso de cocaína/crack à ocorrência de alguma complicação clínica na gestação. Conclusão O abuso de substâncias lícitas ou ilícitas na gestação é frequente e associado a piores desfechos maternos, perinatais e do desenvolvimento infantil.
