Hearing Screening In A Neonatal Intensive Care Unit.

Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Women's Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors. 979 newborn babies were assessed between January 2000 and January 2003, through automated auditory brainstem response (AABR) (ALGO 2e color screener). The result was considered normal when the newborn showed response to a 35dBNA signal bilaterally. The prevalence of AABR impairment and the odds ratio were analyzed with a 95% confidence interval using bivariate analysis. To identify the independent risk factors for hearing alterations, multivariate analyses were used with logistic regression. The prevalence of AABR impairment was 10.2%, of which 5.3% was unilateral and 4.9% bilateral. From the multivariate analyses, the following observations were made: family history of congenital hearing loss (OR = 5.192; p = 0.016), craniofacial deformity (OR = 5.530; p < 0.001), genetic syndromes associated with hearing loss (OR = 4.212; p < 0.001), weight below 1,000 g (OR = 3.230; p < 0.001), asphyxia (OR = 3.532; p < 0.001), hyperbilirubinemia (OR = 4.099; p = 0.002) and use of mechanical ventilation (OR = 1.826; p < 0.031) were the indicators that best characterized the group at risk for hearing impairment. The prevalence of hearing impairment using AABR is high. Therefore, it is essential for all newborns who present isolated or associated risk factors to undergo hearing screening in situations in which it is not possible to have universal hearing screening.82110-

Incidence Of Periventricular/intraventricular Hemorrhage In Very Low Birth Weight Infants: A 15-year Cohort Study.

To assess the incidence of periventricular/intraventricular hemorrhage (PIVH) in very low birth rate neonates. This was a prospective cohort study conducted on a sample of very low birth weight infants over a 15-year period. Neonates who did not undergo cerebral ultrasonography, had malformations affecting the central nervous system, or died within the first 24 hours of life were excluded. Ultrasonography was performed through the anterior fontanelle using an Aloka® 620 scanner with a 5 mHz probe, between days 1 and 3 of life, at 7 days, and at 28 days (or at discharge). Incidence was analyzed by means of the chi-square test for trend or Cochran-Armitage test and through a simple linear regression model with a logarithmic trendline as the output. For assessment of potential associated factors, a variety of obstetric, perinatal, and neonatal data collected between 1991-1994 and 2002-2005 were analyzed, using the chi-square and Fisher's exact tests for statistical analysis. The significance level was set at 5%. Of 1,777 very low birth weight infants born during the study period, 1,381 (77.7%) were examined. Of these, 289 (20.9%) had PIVH. The yearly distribution of cases showed a progressive decline in incidence, from 50.9% in 1991 to 11.9% in 2005 (p < 0.0001). The incidence of PIVH decreased across all weight ranges as well as at grades I/II and III/IV. Significant differences in antenatal corticosteroid use, gender (male), weight (< 1,000 g), hyaline membrane disease, mechanical ventilation, administration of surfactant, patent ductus arteriosus, and sepsis were found. The incidence of PIVH in very low birth weight infants declined significantly during the study period.87505-1

MÉTODOS: Foi realizado estudo de coorte prospectiva de recém-nascidos de muito baixo peso ao longo de 15 anos. Excluíram-se aqueles sem avaliação por ultrassonografia cerebral, com má-formação do sistema nervoso central ou falecidos antes de 24 horas de vida. Os exames foram realizados através da fontanela anterior, utilizando-se ecógrafo Aloka® 620 e transdutor de 5 mHz, entre o primeiro e o terceiro dia de vida, e também no sétimo e no 28º dia de vida e/ou na alta hospitalar. A incidência foi analisada pelo teste de qui-quadrado de tendência ou pelo Cochran-Armitage test, e pelo modelo de regressão linear simples (curva de tendência logarítmica). Para avaliação dos possíveis fatores associados, analisaram-se dados obstétricos, perinatais e neonatais nos períodos de 1991/1994 e 2002/2005, com cálculo do teste de qui-quadrado / Fisher e do risco relativo. O nível de significância foi de 5%. RESULTADOS: Nasceram 1.777 crianças de muito baixo peso, e 1.381 (77,7%) foram avaliadas. Dessas, 289 (20,9%) apresentaram HPIV. A distribuição anual mostrou queda na incidência, de 50,9% em 1991 para 11,9% em 2005 (p < 0,0001). A HPIV apresentou queda em todas as faixas de peso e nos grupos com grau I/II e III/IV. Observaram-se diferenças relacionadas a uso de esteroide antenatal, sexo masculino, peso < 1.000 g, doenças de membranas hialinas, ventilação mecânica, uso de surfactante, canal arterial e sepse. CONCLUSÃO: Houve queda significativa na incidência da doença em recém-nascidos de muito baixo peso ao nascer durante o período analisado.50551

Babies with brain damage who can not swallow: surgical management

BACKGROUND: Neonates with severe neurological impairment are often unable to swallow, necessitating gastrostomy for feeding. Because of the risk of developing severe reflux, this procedure is often associated with fundoplication. OBJECTIVE: To assess the safety and efficacy of gastrostomy and Nissen fundoplication in 22 neonates with swallowing difficulties due to serious neurological impairment. METHOD: All children underwent an initial period of nasogastric feeding and after informed consent underwent gastrostomy and Nissen fundoplication. RESULTS: There were no significant intraoperative complications. There were two cases of postoperative periostomy leakage. Of the 22 neonates 16 were alive four months after surgery. Six neonates died of complications due to underlying disease. CONCLUSION: We concluded that gastrostomy and Nissen fundoplication are safe procedures and help parents give a better care to these children.INTRODUÇÃO: Neonatos com dano neurológico são freqüentemente incapazes de deglutir necessitando de gastrostomia para alimentação. Devido ao risco de refluxo grave, esse procedimento é associado à fundoplicatura. OBJETIVO: Avaliar a segurança e eficácia da gastrostomia com fundoplicatura Nissen em 22 neonatos com dificuldades de deglutição devido à lesão neurológica grave. MÉTODO: Todos os neonatos foram submetidos a um período inicial de alimentação por sonda nasogástrica e, após consentimento informado, foram submetidos a gastrostomia com fundoplicatura Nissen. RESULTADOS: Não houve complicações intra-operatórias significativas. Houve dois casos de vazamento pós-operatório da ostomia. Dos 22 neonatos, 16 estavam vivos 4 meses após a cirurgia. Seis neonatos morreram por complicações devido à doença de base. CONCLUSÃO: A gastrostomia com fundoplicatura Nissen é procedimento seguro e ajuda os pais a darem melhor cuidado a crianças com lesão neurológica

Triagem auditiva em recém-nascidos internados em UTI neonatal Hearing screening in a neonatal intensive care unit

OBJETIVO: Avaliar a prevalência de alterações auditivas em recém-nascidos internados na unidade de terapia intensiva e cuidados intermediários do serviço de neonatologia do Centro de Assistência Integral à Saúde da Mulher, Faculdade de Ciências Médicas, Universidade Estadual de Campinas, e analisar os fatores de risco associados. MÉTODOS: Foram avaliados 979 recém-nascidos no período de janeiro de 2000 a janeiro de 2003, utilizando-se a audiometria automática de tronco encefálico (AABR), com aparelho ALGO-2e color - Natus. O resultado foi considerado normal quando o recém-nascido apresentou resposta para 35 dBNA bilateralmente. Foi analisada a prevalência de AABR alterada e odds ratio com intervalo de confiança de 95% em análise bivariada. Para identificar os fatores de risco independentes para AABR alterada, foi feita análise múltipla com modelo de regressão logística. RESULTADOS: A prevalência de alteração no AABR foi de 10,2%, sendo 5,3% unilateral e 4,9% bilateral. Pela análise multivariada, observamos que: antecedente familiar (OR = 5,192; p = 0,016), malformação craniofacial (OR = 5,530; p OBJECTIVE: Investigate the prevalence of hearing impairment in newborns hospitalized at the Intensive and Intermediate Care Unit at the Women's Comprehensive Health Center Neonatology Service (UNICAMP) and associated risk factors.

CONCLUSÕES: A prevalência de alteração auditiva pela AABR é elevada. É essencial que todos os recém-nascidos que apresentam fatores de risco associados ou isolados passem por avaliação auditiva nas situações em que não seja possível ter a triagem universal.11011
