Objective: To evaluate the maternal and perinatal outcomes of pregnancies delivered at 23+0 to 23+6 weeks' gestation .Methods: This prospective cohort study included women in the Canadian Perinatal Network who were admitted to one of 16 Canadian tertiary perinatal units between August 1, 2005, and March 31, 2011, and who delivered at 23+0 to 23+6 weeks' gestation . Women were included in the network if they were admitted with spontaneous preterm labour with contractions, a short cervix without contractions, prolapsing membranes with membranes at or beyond the external os or a dilated cervix, preterm premature rupture of membranes, intrauterine growth restriction, gestational hypertension, or antepartum hemorrhage . Maternal outcomes included Caesarean section, placental abruption, and serious complication . Perinatal outcomes were mortality and serious morbidity .Results: A total of 248 women and 287 infants were included in the study . The rate of Caesarean section was 10 .5% (26/248) and 40 .3% of women (100/248) had a serious complication, the most common being chorioamnionitis (38 .6%), followed by blood transfusion (4 .5% (25/25) . Two subgroup analyses were performed: in one, antepartum stillbirths were excluded, and in the other only centres that indicated they offered fetal monitoring at 23 weeks' gestation were included and antepartum stillbirths were excluded . In each of these, perinatal outcomes similar to the overall group were found . Conclusion:Pregnant women delivering at 23 weeks' gestation are at risk of morbidity . Their infants have high rates of serious morbidity and mortality . Further research is needed to identify strategies and forms of management that not only increase perinatal survival but also reduce morbidities in these extremely low gestational age infants and reduce maternal morbidity .

“…Esse resultado condiz com o baixo emprego de surfactante observado nos nascimentos com peso inferior a 1.000g. Alguns países europeus reservam condutas mais pró-ativas aos recém-nascidos de maior viabilidade 2,18,24,25 , porém cabe comentar que, nesses locais, há parâmetros definidos para o emprego de tais condutas e há participação de familiares no processo de definição desses parâ-metros 26,27 .…”

Sobrevida e fatores de risco para mortalidade neonatal em uma coorte de nascidos vivos de muito baixo peso ao nascer, na Região Sul do Município de São Paulo, Brasil

Estudos populacionais sobre mortalidade neonatal de nascimentos de muito baixo peso ao nascer contribuem para identificar sua complexa rede de fatores de risco. Foi estudada uma coorte de 213 recém-nascidos com peso inferior a 1.500g (112 óbitos neonatais e 101 sobreviventes) na Região Sul do Município de São Paulo, Brasil, em 2000/2001. Foram realizadas entrevistas domiciliares e obtidos dados de prontuários hospitalares. Foi realizada análise de sobrevida e empregada regressão múltipla de Cox. A elevada mortalidade na sala de parto, no primeiro dia de vida e ausência de sobreviventes < 700g dos nascimentos < 1.000g e com menos de 28 semanas sugere que condutas mais ativas destinam-se a nascituros de maior viabilidade. Mães residentes em favela, com história anterior de cesárea e aborto provocado, adolescentes, com sangramento vaginal e ausência de pré-natal aumentaram o risco de óbito neonatal. Partos cesarianos e internação em berçários mostraram efeito protetor. O peso ao nascer abaixo de 1.000g e Apgar menor que 7 foram risco. A elevada mortalidade está associada às condições de vida, características maternas e dos nascimentos e condições assistenciais. A melhoria da atenção pré-natal e ao recém-nascido pode atuar na redução da mortalidade.

“…infants with BWs <1000 g or gestational age (GA) <28 weeks. Studies have shown that many of these children survive with significant shortand long-term neurodevelopmental sequelae (Hack et al 1996;Wood et al 2003, Mikkola et al 2005, and a significant proportion of them (2-3%) become blind or severely visually impaired (Mikkola et al 2005;Tommiska et al 2007;Jacobson et al 2009). However, there are few long-term studies specifically addressing the ocular and visual problems in children born extremely preterm (Hebbandi et al 1997;Spencer 2006).…”

ABSTRACT.Purpose: Progress in neonatal care has caused an increased survival of children born extremely preterm. The aims of this study were to examine the long-term visual function and ocular development in an unselected cohort of extremely preterm infants and relate the results to neonatal morbidity and long-term neurodevelopmental outcome. Methods: All children with gestational age of 22-27 completed weeks or birth weight of 500-999 g born in the years 1999-2000 in two counties of Western Norway (n = 52) were invited to an eye examination that included visual acuity, refractive error, binocular function, accommodative amplitude and fundus examination. Cognitive function was assessed with the WPSSI-R test and motor abilities with the ABC movement test. Results: Neonatal morbidities and neurodevelopmental outcome were known for all, while 37 of the 52 children underwent the eye examination. None were blind or visually impaired, but 46% had subnormal visual acuity (logMAR ‡0.1). Ninety per cent were emmetropic or slightly hypermetropic (0 to +3D), while 10% had manifest and 51% latent strabismus. Performance IQ on the WPSSI-R test and ABC total score were associated with best visual acuity (p = 0.03 and p < 0.01, respectively). In a multiple linear regression model, visual acuity in the best eye was significantly associated with performance IQ (p = 0.03) and ABC total score (p = 0.02). Conclusion: This study suggests a more favourable long-term prognosis on important ocular and visual parameters in survivors of extreme prematurity than expected from similar reports on children born less prematurely and that performance IQ and motor function are related to visual acuity.
