RESUMO

Objective: Covid-19 poses a major risk during pregnancy and postpartum, resulting in an increase in maternal mortality worldwide, including in Brazil; however, little research has been conducted into cases of a near miss. This study aimed to describe the frequency of COVID-19-related near miss and deaths during pregnancy or in the postpartum in referral centers in northeastern Brazil, as well as the clinical, epidemiological, and laboratory characteristics of the women who experienced a severe maternal outcome.Methods: A retrospective and prospective cohort study was performed between April 2020 and June 2021 with hospitalized pregnant and postpartum women with a diagnosis of COVID-19 confirmed by real-time polymerase chain reaction (RT-PCR). Data from five tertiary hospitals in northeastern Brazil were evaluated. Descriptive statistical analysis was performed using Epi Info, version 7.2.5.0.Results: A total of 463 patients were included. Of these, 64 (14% of the sample) had a severe maternal outcome, with 42 cases of near miss (9%) and 22 maternal deaths (5%). Patients who had a severe maternal outcome were predominantly young (median age 30 years) and 65.6% were black or brown-skinned. The women had between 6 and 16 years of schooling; 45.3% had a stable partner; 81.3% were pregnant at the time of admission to the study; and 76.6% required a Cesarean section. The great majority (82.8%) had severe acute respiratory syndrome (SARS). Other complications included hypertensive syndromes (40.6%), pneumonia (37.5%), urinary tract infections (29.7%), acute renal failure (25.0%) and postpartum hemorrhage (21.9%). Sepsis developed in 18.8% of cases, neurological dysfunction in 15.6%, and hepatic dysfunction and septic shock in 14.1% of cases each. The relative frequency of admission to an intensive care unit was 87.5%, while 67.2% of the patients required assisted mechanical ventilation, and 54.7% required noninvasive ventilation. Antibiotics were prescribed in 93.8% of cases and corticosteroids in 71.9%, while blood transfusion was required in 25.0% of cases and renal replacement therapy in 15.6%. Therapeutic anticoagulants were administered to 12.5% of the patients. Of the patients who had a severe maternal outcome, the frequency of respiratory dysfunction was 93.8%, with 50.0% developing neurological dysfunction and 37.5% cardiovascular dysfunction. Hematological dysfunction was found in 29.7%, renal dysfunction in 18.8%, and uterine dysfunction in 14.1%. Hepatic dysfunction occurred in 7.8% of the sample. The near-miss ratio for Covid-19 was 1.6/1000 live births and the maternal mortality ratio for Covid-19 was 84.8/100,000 live births, with a mortality index of 34.4% in the sample.Conclusion: This study revealed a low Covid-19-related maternal near miss (MNM) ratio of 1.6/1000 live births and a high Covid-19-related maternal mortality ratio (MMR) of 84.81/100,000 live births. The mortality index was also high. Most of the patients were admitted while pregnant, were young, married and black or brown-skinned, and none had completed university education. The majority had SARS and required admission to an intensive care unit and mechanical ventilation. Most were submitted to a Cesarean section.

RESUMO

Maternal RhD alloimmunization is an inflammatory response against protein antigens in fetal red blood cells (RBC). However, not all women become alloimmunized when exposed to RhD+ fetal RBC. Thus, this study aimed to evaluate levels of inflammatory chemokines in RhD- pregnant women with erythrocyte alloimmunization. CXCL8, CXCL9, CCL5, and CXCL10 levels were determined from cell culture supernatants by flow cytometry in 46 (30 non-alloimmunized RhD- and 16 previously alloimmunized RhD-) pregnant women. CXCL8 levels were significantly higher (P < 0.004), and CXCL9 (P < 0.008) and CXCL10 (P < 0.003) levels were significantly lower in alloimmunized pregnant women. No significant difference in CCL5 levels was detected between the groups. Fetal RHD genotyping was performed in the alloimmunized RhD- group by real-time PCR. Anti-D alloantibody was detected in 10 mothers and anti-D and -C in six mothers. Twelve fetuses were RHD positive and four were RHD negative. Further studies of serum chemokines and placenta tissue could provide a better understanding of the cells involved in the pathogenesis of maternal erythrocyte alloimmunization.

RESUMO

BACKGROUND: Despite all the evidence corroborating the selective use of episiotomy and although routine use of the procedure is contraindicated, there are no evidences corroborating if episiotomy is necessary in any circumstance. The present clinical randomized trial was performed to compare maternal and perinatal outcomes in women submitted to a non-episiotomy protocol versus one of selective episiotomy. METHODS: An open-labelled, randomized clinical trial was carried out in a tertiary teaching hospital in Recife, Northeastern Brazil. Women in labor with a full-term live foetus, dilatation of 6 to 8 cm and cephalic presentation (vertex position) were included. Exclusion criteria consisted of bleeding disorders and an indication for a caesarean section. After signing the consent form, 241 women were randomized to a non-episiotomy protocol (the experimental group) or to a selective episiotomy group (the control group). No episiotomies were to be performed in the experimental group except under exceptional circumstances. In the control group, selective episiotomies were to be performed in accordance with the healthcare professionals' clinical judgement. Maternal and perinatal outcomes were evaluated. Ratio Risk (RR) and the 95% confidence interval (95% CI) were calculated for our outcomes. RESULTS: The analysis include 115 women assigned to a non-episiotomy protocol and 122 to selective episiotomy. There was no difference between the two groups with respect to maternal or perinatal outcomes. The episiotomy rate was similar (two cases in each group, about 1.7%), as was the duration of the second stage of labor, the frequency of perineal tears, severe perineal trauma, need for perineal suturing and blood loss at delivery. CONCLUSIONS: A non-episiotomy protocol appears to be safe for mother and child, and highlights the need to investigate whether there is, in fact, any indication for this procedure. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov under reference number ( NCT02178111 ).

RESUMO

OBJECTIVE: This study aimed to identify risk factors associated with the persistence/recurrence of cervical intraepithelial neoplasia (CIN) 2/3 in women submitted to loop electrosurgical excision procedure (LEEP) in a hospital in northeastern Brazil. MATERIALS AND METHODS: A case-control study included 50 women with and 50 women without persistence/recurrence of CIN2/3 after LEEP at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) between 2004 and 2011. Data were collected from June to December 2011. Inclusion criteria were diagnosis of CIN2/3 during follow-up (cases) and women free of CIN2/3 after a follow-up of 2 years or longer (controls). Exclusion criteria (cases/controls) were LEEP performed at another hospital, LEEP performed for persistent CIN1, invasive carcinoma in the cone specimen or at cytology, and/or histopathology within a 2-year follow-up period. Persistence was defined as residual disease detected in the first year after LEEP, and recurrence was defined as the reappearance of a lesion more than 1 year after surgery. Bivariate analysis was performed for biological, sociodemographic, sexual, reproductive, lifestyle, and clinical variables. Odds ratios (ORs) and their 95% confidence intervals (95% CIs) were calculated, and a multiple logistic regression analysis was performed to control for potential confounding factors. The study was approved by IMIP's internal review board. RESULTS: Multiple logistic regression analysis showed a significant association between persistence/recurrence of CIN2/3 and living outside the capital city (OR=3.11, 95% CI=1.14-8.41), smoking (OR=4.22, 95% CI=1.18-15.05), and positive endocervical margins (OR=6.58, 95% CI=2.37-18.28). CONCLUSIONS: Women with persistence/recurrence of CIN2/3 are more likely to live outside the state capital, be smokers, and have positive endocervical margins, so these women should be followed up more closely.

RESUMO

OBJECTIVE: The objective of this study was to compare maternal satisfaction with childbirth according to whether or not combined spinal-epidural anesthesia (CSE) of pain relief was used during labor. METHODS: A randomized, open clinical trial was performed with 70 pregnant women, 35 of whom received CSE anesthesia while 35 received only non-pharmacological forms of pain relief during labor. The variables evaluated were visual analogue scale (VAS) pain score, maternal satisfaction with the technique of pain relief used during childbirth and with delivery, the patient's intention to request the same technique in a subsequent delivery, and loss of control during delivery. RESULTS: VAS pain score decreased significantly in patients receiving CSE during vaginal delivery. Furthermore, maternal satisfaction with the technique of pain relief and with delivery was higher in the CSE group, and around 97% of the patients would repeat the same technique at future deliveries compared to 82.4% of the women in the group using only non-pharmacological methods. With respect to the women's impressions of their control during delivery, approximately half the women in both groups felt that they had lost control at some point during the process. CONCLUSION: The use of CSE was associated with a significant reduction in VAS pain scores during delivery and with greater maternal satisfaction with the pain relief method and with the childbirth process.

OBJETIVOS: Comparar a satisfação materna com o processo do nascimento de acordo com a realização ou não de métodos farmacológicos para alívio da dor do trabalho de parto. MÉTODOS: Realizou-se um ensaio clínico randomizado com 70 parturientes, 35 das quais receberam anestesia combinada (raquidiana e peridural associadas) e 35 receberam métodos não farmacológicos para alívio da dor durante o parto vaginal. As variáveis estudadas foram: escores de dor pela Escala Visual Analógica (EVA), satisfação materna com a técnica analgésica e com o parto, desejo de repetir a técnica analgésica em parto posterior e perda do controle sobre o parto. A análise estatística foi realizada no programa Epi-Info 3.5.3, com base na intenção de tratar. RESULTADOS: Pacientes recebendo anestesia combinada (AC) durante o parto vaginal experimentaram uma diminuição significativa dos escores da EVA e maior satisfação materna com a técnica analgésica e com o parto. A maioria das parturientes, cerca de 97 por cento do grupo da anestesia combinada, repetiu a técnica em partos futuros, contra 82,4 por cento do grupo dos métodos não farmacológicos. No que diz respeito ao sentimento de controle do parto, aproximadamente metade das parturientes dos dois grupos sentiu que em algum momento do parto perdeu o controle deste, não havendo diferença significativa entre os grupos. CONCLUSÃO: O uso da AC está associado a uma significante diminuição dos escores da dor durante o parto, e maior satisfação materna com a técnica analgésica e com o parto.

RESUMO

OBJECTIVES: To determine the effectiveness of corticosteroids in reducing respiratory disorders in infants born at 34-36 weeks' gestation. Design Randomised triple blind clinical trial. Setting A large tertiary teaching hospital in northeast of Brazil. Participants Women at 34-36 weeks of pregnancy at risk of imminent premature delivery. Interventions Betamethasone 12 mg or placebo intramuscularly for two consecutive days. Main outcomes measures Primary outcome was the incidence of respiratory disorders (respiratory distress syndrome and transient tachypnoea of the newborn). Secondary outcomes included the need for ventilatory support, neonatal morbidity, and duration of stay in hospital. RESULTS: 320 women were randomised, 163 of whom were assigned to the treatment group and 157 to the controls. Final analysis included 143 and 130 infants, respectively. The rate of respiratory distress syndrome was low (two (1.4%) in the corticosteroid group; one (0.8%) in the placebo group; P = 0.54), while the rate of transient tachypnoea was high in both groups (34 (24%) v 29 (22%); P = 0.77). There was no reduction in the risk of respiratory morbidity with corticosteroid use even after adjustment for subgroups of gestational age (34-34(+6) weeks, 35-35(+6) weeks, and ≥ 36 weeks). The adjusted risk of respiratory morbidity was 1.12 (95% confidence interval 0.74 to 1.70). The need for ventilatory support was around 20% in both groups. There was no difference in neonatal morbidity (88 (62%) v 93 (72%); P = 0.08) or in the duration of stay in hospital between the two groups (5.12 v 5.22 days; P = 0.87). Phototherapy for jaundice was required less often in babies whose mothers received corticosteroids (risk ratio 0.63, 0.44 to 0.91). CONCLUSIONS: Antenatal treatment with corticosteroids at 34-36 weeks of pregnancy does not reduce the incidence of respiratory disorders in newborn infants. Trial registration Clinical Trials NCT00675246.

RESUMO

OBJECTIVE: To evaluate Doppler velocimetry parameters (resistance index [RI], pulsatility index [PI] and systolic/diastolic [S/D] ratio) of maternal-fetal circulation before and after magnesium sulfate administration in pregnant women with severe preeclampsia. METHODS: A prospective observational cohort analysis of 40 women with severe preeclampsia was performed. Doppler ultrasonography scans were performed before and 20 minutes after intravenous administration of magnesium sulfate. Maternal parameters such as heart rate, and systolic, diastolic and mean arterial pressure were recorded. Doppler flow velocity parameters (RI, PI and S/D ratio) were evaluated in the uterine, umbilical and middle cerebral arteries. The different mean values obtained before and after magnesium sulphate were analyzed using the paired t-test. RESULTS: There was a statistically significant increase in mean maternal heart rate and a statistically significant decrease in systolic, diastolic and mean maternal blood pressure before and after administration of magnesium sulphate (p < 0.001). Resistance index decreased in the umbilical (p = 0.003; 95% CI: 0.008 - 0.03) and middle cerebral artery (p = 0.001; 95% CI: 0.01 - 0.05) and in both uterine arteries. Likewise, there was a significant reduction in the PI and S/D ratio in all the arteries assessed. CONCLUSIONS: Maternal administration of intravenous magnesium sulfate in preeclampsia leads to an increase in maternal heart rate and a decrease in systolic, diastolic and mean arterial blood pressure. A reduction in the resistance index, pulsatility index and S/D ratio was recorded in the uterine, umbilical and cerebral arteries.

RESUMO

OBJETIVO: comparar a efetividade da nitroglicerina transdérmica com a nifedipina oral na inibição do trabalho de parto prematuro. MÉTODOS: foi realizado um ensaio clínico com 50 mulheres em trabalho de parto prematuro, randomizadas em dois grupos, 24 para nifedipina oral (20 mg) e 26 para nitroglicerina transdérmica (patch 10 mg). Foram selecionadas as pacientes com gestação única, entre a 24ª e 34ª semanas e diagnóstico de trabalho de parto prematuro. Foram excluídas pacientes com malformações fetais e com doenças clínicas ou obstétricas. As variáveis analisadas foram tocólise efetiva, tempo necessário para tocólise, frequência de recorrência, progressão para parto prematuro e efeitos colaterais. RESULTADOS: a eficácia da tocólise nas primeiras 12 horas foi semelhante entre os grupos (nitroglicerina: 84,6 por cento versus nifedipina: 87,5 por cento; p=0,5). A média do tempo para tocólise também foi semelhante (6,6 versus 5,8 horas; p=0,3). Não houve diferença entre os grupos quanto à recorrência de parto prematuro (26,9 versus 16,7 por cento; p=0,3) e nem na frequência de parto prematuro dentro de 48 horas (15,4 versus 12,5 por cento; p=0,5). Entretanto, a frequência de cefaleia foi significativamente maior no grupo que usou nitroglicerina (30,8 versus 8,3 por cento; p=0,04). CONCLUSÕES: a nitroglicerina transdérmica apresentou efetividade semelhante à nifedipina oral para inibição do trabalho de parto prematuro nas primeiras 48 horas, porém com maior frequência de cefaleia.

PURPOSE: to compare the effectiveness of transdermal nitroglycerin with oral nifedipine in the inhibition of preterm delivery. METHODS: a clinical essay has been performed with 50 women in preterm delivery, randomly divided into two groups, 24 receiving oral nifedipine (20 mg), and 26, transdermal nitroglycerin (10 mg patch). Patients with a single gestation, between the 24th and the 34th weeks and diagnosis of preterm delivery were selected. Women with fetal malformation and clinical or obstetric diseases were excluded. The variables analyzed were: effective tocolysis, time needed for tocolysis, recurrence frequency, progression to preterm delivery, and side effects. RESULTS: tocolysis efficacy in the first 12 hours was similar between the groups (nitroglycerin: 84.6 percent versus nifedipine: 87.5 percent; p=0.50). The time average time needed for tocolysis was also similar (6.6 versus 5.8 hours; p=0.30). There was no difference between the groups, concerning the recurrence of preterm delivery (26.9 versus 16.7 percent; p=0.30), and neither in the rate of preterm delivery within 48 hours (15.4 versus 12.5 percent; p=0.50). Nevertheless, the cephalea rate was significantly higher in the Nitroglycerin Group (30.8 versus 8.3 percent; p=0.04). CONCLUSIONS: transdermal nitroglycerin has presented similar effectiveness to oral nifedipine to inhibit preterm delivery in the first 48 hours, however with higher cephalea frequency.

RESUMO

OBJECTIVE: To compare extra-abdominal to intra-abdominal repair of the uterine incision at cesarean delivery. METHODS: This is a randomized controlled trial conducted at the Instituto Materno-Infantil Prof. Fernando Figueira (Recife, Brazil). Inclusion criteria were indication for cesarean delivery and gestational age of 24 weeks or more. Patients with two or more cesarean deliveries, chorioamnionitis, hemorrhage, inability to consent, and previous abdominal surgery were excluded. Variables analyzed were nausea, vomiting, mean operative time, intraoperative blood loss, number of surgical sutures for uterine repair, postoperative pain evaluated by the visual analog scale, number of postoperative analgesic doses, surgical site infection, and endometritis. RESULTS: The analysis included 325 patients randomized for exteriorized uterine repair and 312 patients randomized for in situ uterine repair. A significant difference was observed in duration of surgery: lasting less than 45 minutes (44% with exteriorized uterus compared with 35.3% with in situ uterus, P=.02; number needed to treat=12) and less need of sutures (18.2% requiring one suture in the exteriorized group compared with 11.9% in the in situ group, P=.03; number needed to treat=16). The frequency of moderate or severe pain 6 hours after surgery was low [corrected] in women with in situ [corrected] repair (23.1%) when compared to those with the uterus exteriorized [corrected] (32.6%) (P=.026; number needed to treat=11). There was no difference between the groups in relation to other variables. CONCLUSION: There is no significant difference between extra-abdominal and intra-abdominal repair of the uterine incision at cesarean delivery, but the number of sutures is lower and surgical time is shorter with extra-abdominal repair, although moderate and severe pain at 6 hours is less frequent with in situ uterine repair.

RESUMO

As síndromes hipertensivas constituem um grupo de intercorrências clínicas que com grande freqüência complicam a gravidez. Acometem cerca de 10 porcento das gestações, encontrando-se entre as principais causas de morte materna e com elevada taxa de morbimortalidade perinatal no mundo, oscilando entre 5 e 20 porcento. O sulfato de magnésio é a droga de escolha para profilaxia e tratamento das convulsões eclâmpticas, e seus efeitos benéficos em termos de prevenção das crises convulsivas e redução da morte materna foram já demonstrados em ensaios clínicos bem controlados. Sugere-se que o magnésio possa ainda exercer um importante papel na regulação da pressão sangüínea por modulação da reatividade do tono vascular e da resistência periférica total. Entretanto, o papel desses efeitos no tratamento dos distúrbios hipertensivos da gravidez não foi ainda elucidado. Desta forma, a presente revisão tem como objetivo descrever os mecanismos de ação do sulfato de magnésio e avaliar seus possíveis efeitos sobre a circulação materno-fetal. Até o momento não foi encontrada nenhuma evidência de que o sulfato de magnésio possa acarretar benefícios hemodinâmicos para a mãe e o feto, existindo muitas controvérsias na literatura.

RESUMO

OBJETIVO: Testar a efetividade e segurança do comprimido sublingual de misoprostol, na dose de 25 mcg a cada seis horas, para indução do parto em gestantes de alto risco internadas em dois hospitais-escola do Nordeste do Brasil. MÉTODOS: Realizou-se um ensaio clínico aberto, não randomizado, incluindo 40 gestantes de alto risco internadas nas Enfermarias de Patologia Obstétrica da Maternidade-Escola Assis Chateaubriand e Instituto Materno-Infantil de Pernambuco. Todas tinham idade gestacional maior que 37 semanas, feto único com boa vitalidade e escores de Bishop menores ou iguais a 7. Utilizou-se o comprimido de 25 mcg de misoprostol via sublingual, repetindo-se a cada seis horas, até no máximo de quatro doses. A análise estatística foi realizada no programa de domínio público Epi-Info 3.2.2. RESULTADOS: O trabalho de parto foi desencadeado em todas as gestantes. O intervalo entre a primeira dose e o início das contrações foi de 4,8±3,8 horas. O intervalo entre a primeira dose e o parto variou de 8 a 31 horas, com 95 por cento dos partos ocorrendo nas primeiras 24 horas, sendo 75 por cento por via vaginal. Houve necessidade de mais de uma dose de misoprostol em 60 por cento dos casos. A taquissistolia ocorreu em 12,5 por cento das gestantes. Não ocorreram complicações neonatais. CONCLUSÃO: O comprimido sublingual de 25 mcg de misoprostol foi efetivo para desencadeamento do trabalho de parto em gestantes de alto-risco. A eficácia desta nova via deve ser comparada à da via vaginal em futuros estudos clínicos randomizados.

RESUMO

As síndromes hipertensivas representam uma das alterações que ocorrem com maior freqüência na gravidez. Sua incidência varia de 2 a 8 porcento das gestações, encontrando-se entre as principais causas de morte materna e com elevada taxa de morbimortalidade perinatal no mundo, oscilando entre 5 e 20 porcento. Devido a graves complicações que a pré-eclâmpsia/eclâmpsia pode acarretar, o assunto será abordado visando melhorar a assistência materno-fetal. A correta classificação e o diagnóstico das síndromes hipertensivas são de grande importância para o acompanhamento destas gestantes. O sulfato de magnésio é a principal droga utilizada nas pacientes com pré-eclâmpsia com o intuito de prevenir futuras convulsões
