ABSTRACT
Abstract Objective To evaluate the association between early-onset fetal growth restriction (FGR), late-onset FGR, small for gestational age (SGA) and adequate for gestational age (AGA) fetuses and adverse perinatal outcomes. Methods This was a retrospective longitudinal study in which 4 groups were evaluated: 1 - early-onset FGR (before 32 weeks) (n=20), 2 - late-onset FGR (at or after 32 weeks) (n=113), 3 - SGA (n=59), 4 - AGA (n=476). The Kaplan-Meier curve was used to compare the time from the diagnosis of FGR to birth. Logistic regression was used to determine the best predictors of adverse perinatal outcomes in fetuses with FGR and SGA. Results A longer timebetween the diagnosis and birthwas observed forAGAthan for late FGR fetuses (p<0.001). The model including the type of FGR and the gestational age at birth was significant in predicting the risk of hospitalization in the neonatal intensive care unit (ICU) (p<0.001). The model including only the type of FGR predicted the risk of needing neonatal resuscitation (p<0.001), of respiratory distress (p<0.001), and of birth at<32, 34, and 37 weeks of gestation, respectively (p<0.001). Conclusion Fetal growth restriction and SGA were associated with adverse perinatal outcomes. The type of FGR at the moment of diagnosis was an independent variable to predict respiratory distress and the need for neonatal resuscitation. The model including both the type of FGR and the gestational age at birth predicted the risk of needing neonatal ICU hospitalization.
Resumo Objetivo Avaliar o efeito da restrição de crescimento fetal (RCF) precoce, RCF tardio, fetos pequenos constitucionais para idade gestacional (PIG) e fetos adequados para idade gestacional (AIG) sobre resultados adversos perinatais. Métodos Estudo longitudinal e retrospectivo, no qual foram avaliados quatro grupos: 1 - RCF precoce (< 32 semanas) (n=20), 2 - RCF tardio ( 32 semanas) (n=113), 3 - PIG (n=59), 4 - AIG (n=476). A curva de Kaplan-Meier foi utilizada para comparar o tempo entre o diagnóstico da RCF e o parto. Regressão logística foi utilizada para determinação dosmelhores previsores de resultados perinatais adversos entre os fetos com RCF e PIG. Resultados Os fetos AIGs apresentaram maior tempo entre o diagnóstico e parto, enquanto fetos RCF tardio apresentaram menor tempo (p<0,001). O modelo contendo tanto os tipos de RCF quanto a idade gestacional no momento do parto foi significativo em predizer o risco de internação na unidade de terapia intensiva (UTI) neonatal (p<0,001). O modelo incluindo apenas o tipo de FGR prediz o risco de ressuscitação neonatal (p<0,001), de desconforto respiratório (p<0,001) e de nascimento<32, 34 e 37 semanas de gestação, respectivamente (p<0,001). Conclusão Os desvios do crescimento, RCF e PIG, foram associados a resultados perinatais adversos. O tipo de RCF no momento do diagnóstico foi variável independente para predizer necessidade de reanimação neonatal e desconforto respiratório. O modelo que incluiu o tipo de FGR e idade gestacional no nascimento prediz o risco de necessitar de internação em UTI neonatal.

Background: Women with intrahepatic cholestasis of pregnancy (ICP) have an increased risk for postpartum haemorrhage, dyslipidaemia, preterm labour and operative interference. Fetus in ICP has been associated with an increased incidence of preterm labour, preterm prelabour rupture of membrane, fetal distress, abnormal CTG, meconium staining, spontaneous intrauterine death. The present study was done to evaluate the perinatal outcomes – maternal outcomes and fetal outcomes of ICP.Methods: This was a prospective observational study carried out in a tertiary care teaching hospital. Total 1100 pregnant women were screened during the study period. Patients with ICP were identified in maternity care units after eliciting history about itching. Pregnancies with pregnancy induced hypertension and other liver diseases in pregnancy were excluded.Results: 62 pregnant women with prevalence rate of 5.64% have been found to be suffering from ICP. The most frequently affected (22, 35.48%) age-group with ICP were belong to age > 35 years. A majority of pregnant women with intrahepatic cholestasis of pregnancy was of multipara. ICP was highly significantly associated with small for gestational age (SGA, p-value: 0.0003); abnormal cardiotocography (CTG, p-value: 0.0002); and meconium stained liquor (p-value: 0.0001). Caesarean section as mode of delivery found significantly associated (p-value: 0.0033) with ICP. Insomnia (p-value: 0.0045); dyslipidemia (p-value: 0.0011); and postpartum haemorrhage (p-value: 0.0122) were also found significantly with ICP.Conclusions: ICP can adversely affect fetal as well as maternal pregnancy outcomes. Maternal outcomes have good prognosis, but fetal outcomes can be improved by timely and effective intervention.
ABSTRACT
Resumen OBJETIVO: Determinar la relación entre complicaciones obstétricas y perinatales con la anemia durante el embarazo. MATERIALES Y MÉTODOS: Estudio ambispectivo, observacional y transversal. Se incluyeron pacientes en trabajo de parto, con embarazo único, atendidas entre marzo y octubre de 2017 en el Hospital General Dr. Salvador Zubirán Anchondo, Chihuahua, Chih. Se excluyeron las pacientes con embarazo complicado por defectos congénitos, que hubieran recibido anticoagulantes, con diagnóstico médico de hemoglobinopatías, hemofilias, preeclampsia, síndrome de HELLP, partos instrumentados y distocias, diabetes gestacional, nefropatías, hepatopatías, tabaquismo y toxicomanías. Complicaciones valoradas: amenaza de aborto, amenaza de parto pretérmino, parto pretérmino, ruptura prematura de membranas, infección de vías urinarias, peso al nacer, valoración de Apgar al minuto y a los 5 minutos, hemorragia obstétrica. Se entrevistó a todas las pacientes para evaluar los antecedentes ginecoobstétricos y se tomó una muestra de sangre venosa para determinar: hemoglobina, hematocrito, cantidad de glóbulos rojos, volumen corpuscular medio, concentración de hemoglobina corpuscular media. Se registraron las mediciones antropométricas, valores de Apgar y complicaciones perinatales del expediente clínico. RESULTADOS: Se estudiaron 1051 pacientes divididas en dos grupos: con anemia (n = 172) y sin anemia (n = 879). Se consideró anemia a la hemoglobina menor de 11 g/dL o hematocrito menor de 33%. Se clasificaron de acuerdo con la OMS como: anemia leve 10-10.9 g/dL, moderada 7-9.9 g/dL y severa menos de 7.0 g/dL. La prevalencia de anemia fue de 16%. La anemia leve se identificó con mayor frecuencia 10% (n = 111), anemia moderada y severa 6% (n = 61). Las complicaciones maternas y neonatales no mostraron asociación con la anemia materna durante el embarazo. La hemotransfusión fue mayor en pacientes con anemia (9 vs 1%). CONCLUSIÓN: Se identificó anemia materna en 16% de los casos y se asoció con necesidad de transfusión de hemoderivados en el posparto o posquirúrgico de cesárea.
Abstract OBJECTIVE: Determinate the association between adverse perinatal outcomes and anemia in pregnant women. MATERIALS AND METHODS: Observational, prospective-retrospective and cross-sectional study. Including women in birth labor attended at Hospital General Dr. Salvador Zubirán Anchondo in Chihuahua City, during March to October 2017. Inclusion criteria considered women with single pregnancy. Exclusion criteria with present conditions: congenital deformities, use of anticoagulants, blood diseases, preeclampsia, HELLP syndrome, instrumental delivery with forceps, dystocia, maternal diabetes, kidney and liver diseases, use of tobacco and other drugs. Adverse perinatal outcomes included were: miscarriage risk, preterm labor, preterm birth, pre labor rupture of membranes, urinary infection, low birth weight, Apgar score at birth and after five minutes, obstetric hemorrhage. Patients were interviewed to evaluate obstetric background; blood venous sample was taken to determine haemoglobin, hematocrit, red blood cells number, medium corpuscular volume, medium corpuscular hemoglobin concentration. Birth data was registered from medical records. RESULTS: Two groups were integrated: with anemia (n=172) and without anemia (n=879). Patients with anemia were those with haemoglobin less than 11 g/dL or hematocrit less than 33% according World Health Organization anemia classification: mild 10-10.9 g/dL, moderate 7-9.9 g/dL and severe less than 7.0 g/dL. Anemia frequency was calculated in 16%, mild anemia frequency was 10% (111 patients), 6% moderate and severe anemia (n = 61). Both groups developed patients with adverse perinatal outcomes. Transfusion of blood products showed higher frequency in anemic patients (9% versus 1% control group). CONCLUSION: Anemia prevalence calculated in 16% associated with transfusion of blood products, during puerperium or after c-section period.
