Associated factors with neonatal near miss in twin pregnancies in a public referral maternity unit in Brazil

Objective: The aim was to analyze the factors associated with neonatal near miss (NNM) in twin pregnancies in a public referral maternity unit in Brazil. Material and Methods: This retrospective, cross-sectional study included 697 twin newborns. Cases of fetal and neonatal deaths were excluded. Neonates were divided into those meeting NNM criteria (5 min Apgar score <7, birth weight <1,500 g, gestational age at delivery <32 weeks, use of mechanical ventilation or congenital malformation, transfer before 28 days of life) and those who did not. In the bivariate analysis, the chi-square and Fisher's exact tests were used. Variables with a p-value ≤0.20 were subjected to the multiple analyses, which followed the Poisson regression model. Results: The cohort consisted of 130 (18.7%) neonates meeting NNM criteria and 567 (81.3%) with no NNM criteria after multiple analyses, the following variables were associated with NNM: no previous pregnancy, prevalence ratio (PR): 1.38 [95% confidence interval (CI), 1.03-1.85]; >3 previous pregnancies, PR: 1.93 (95% CI, 1.38-2.69); premature rupture of membranes, PR: 1.50 (95% CI, 1.70-2.12); intrauterine growth restriction, PR: 2.28 (95% CI, 1.53-3.33); premature labor, PR: 1.63 (95% CI, 1.13-2.35); resuscitation in the delivery room, PR: 1.80 (95% CI, 1.24-2.62); and transfusion of blood products, PR: 4.44 (95% CI, 3.14-6.28). Conclusion: The study findings indicate that having had 0 or >3 previous pregnancies, premature rupture of the membranes, intrauterine growth restriction, resuscitation in the delivery room, premature labor, and transfusion of blood products were associated with NNM in twin pregnancies.

Factors associated with neonatal near miss and death in public referral maternity hospitals / Fatores associados ao near miss e óbito neonatais em maternidade pública de referência

Abstract Objectives: to evaluate factors associated with neonatal near miss and death in reference hospitals. Methods: this case-control study included 364 cases and 728 controls among 4,929 births. Cases were identified by Apgar < 7 at 5 minutes, weight < 1500 g, gestational age <32 weeks, mechanical ventilation or congenital malformation. After follow-up, outcomes were reclassified into: true controls, near miss and neonatal death. Hierarchically, variables with a p-value < 0.20 were included in the multiple logistic regression. Results: the neonatal near miss rate was 54.1 per 1,000 live births, and the near-miss-to-death ratio was 2.75. Between the control and near miss groups, the predictor variables were neonatal intensive care admission [OR = 35.6 (16.7 - 75.9)] and central venous access [OR= 74.8 (29.4 - 190.4)]. Between the control and death groups, neonatal intensive care admission [OR = 100.4 (18.8 - 537.0)] and central venous access [OR = 12.7 (3.7 - 43.2)] were significant. Between the near miss and death groups, only Apgar < 7 at 5 minutes [OR = 4.1 (1.6 - 10.6)] and vasoactive drug use [OR = 42.2 (17.1 - 104.5)] were significant. Conclusion: factors associated with a greater chance of near miss and/or neonatal death were: Apgar score <7 at 5 minutes, neonatal intensive care confinement, having central venous access, and use of vasoactive drugs.

Conclusão: fatores associados à ocorrência de near miss e/ou óbito neonatal foram: Apgar < 7 no 5° minuto, internamento em terapia intensiva neonatal, acesso venoso central e drogas vasoativas.

Delays in obstetric care increase the risk of neonatal near-miss morbidity events and death: a case-control study.

BACKGROUND: To evaluate the association between delays in obstetric care and neonatal near-miss mortality events and death in a public maternity referral center. METHODS: This case-control study enrolled 142 neonates, meeting the near-miss criteria of 5-min Apgar < 7, weight < 1500 g, gestational age < 32 weeks, and use of mechanical ventilation or congenital malformation, as well as 284 controls (without the near-miss criteria), at a ratio of 1:2. After follow-up, the following outcomes were reclassified: survival of the neonatal period without the near-miss criteria (true "controls"), "near-miss," and "neonatal death." Maternal sociodemographic characteristics, prenatal care, and pregnancy resolution were evaluated. Pearson's chi-square and Fisher's exact tests were used. Simple logistic regression was performed to determine the association between the three delay factors with near-miss outcomes and/or neonatal death. The variables that had maintained values of p < 0.05 were subjected to multinomial logistic regression. RESULTS: Comparisons revealed the following associations: for controls and near-miss events, delayed access to health services due to a lack of specialized services (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.8-5.1) and inappropriate conduct with the patient (OR, 12.1; 95% CI, 1.3-108.7); for controls and death, absent or inadequate prenatal care (OR, 3.3; 95% CI, 1.6-7.1) and delayed access to health services due to a lack of specialized services (OR, 2.5; 95% CI, 1.1-5.6); and for near-miss events and death, absent or inadequate prenatal care (OR, 2.2; 95% CI, 1.0-5.0). Logistic regression for the combined outcome (near-miss plus neonatal deaths) revealed absent or inadequate prenatal care (OR, 1.9; 95% CI, 1.2-2.8), lack of specialized services (OR, 2.8; 95% CI, 1.7-4.5), and improper conduct with the patient (OR, 10.6; 95% CI, 1.2-91.8). CONCLUSIONS: The delays in obstetric care associated with the presence of near-miss and/or neonatal death included absent or inadequate prenatal care, delayed access to health services due to a lack of specialized services, and inappropriate conduct with the patient.

Late umbilical cord clamping does not increase rates of jaundice and the need for phototherapy in pregnancies at normal risk.

Objective: To verify the relationship between the time of clamping of the umbilical cord and the development of neonatal jaundice, the dosage of bilirubin and the need for phototherapy. Methods: Cross-sectional, retrospective study with 398 parturients at normal risk (single term gestation, no complications during gestation or delivery, birth weight between 2500 and 4499 g). The population was divided into three groups regarding the time of cord clamping: <1 min(117, 29.4%), between 1 and 3 min(228, 57.3%) and >3 min(53, 13.3%). Sociodemographic, clinical and obstetric characteristics, birth and delivery data, and maternal and perinatal outcomes were evaluated. Pearson's chi-square test, Fisher's exact test and the Kruskal-Wallis test were used for comparison between the groups. Statistical significance was considered p < .05. Results: The groups were similar in the development of jaundice (p = .370), bilirubin dosage (p = .342) and need for phototherapy (p = .515). Late clamping was more prevalent in vaginal deliveries when compared to cesarean sections (1-3 min: 64 versus 21.4%, >3 min: 16.6 versus 1%) (p < .001). There was no difference in other maternal or perinatal variables. Conclusion: The clamping time of the umbilical cord showed no association with jaundice, bilirubin dosage, or phototherapy needs in neonates at normal risk. The adoption of late clamping was more prevalent in vaginal deliveries.
