O cuidado em saúde no ciclo gravídico-puerperal sob a perspectiva de usuárias de serviços públicos

O objetivo do trabalho foi apreender as representações sociais de puérperas sobre o cuidado em saúde no período pré-natal, no parto e no puerpério, em um contexto regional de serviços públicos de saúde do interior paulista. Seguindo a abordagem de pesquisa qualitativa, os dados foram colhidos por meio de entrevistas semi-estruturadas, realizadas em 2004, e organizados segundo o método do Discurso do Sujeito Coletivo, tendo o Programa de Humanização do Pré-natal e Nascimento (PHPN) como referencial teórico para discussão dos resultados. A perspectiva das puérperas sobre o cuidado em saúde no ciclo gravídico-puerperal evidenciou a importância das relações interpessoais, a essencialidade da qualidade técnica do atendimento e a propriedade da percepção de que o sujeito da atenção é a mulher e, como tal, dela deve participar efetivamente. Conclui-se que as diretrizes do PHPN devem ser incorporadas de forma mais ampla nas práticas de saúde voltadas à mulher, recomendando-se a adoção de indicadores específicos para avaliação das dimensões do cuidado evidenciadas por este estudo.

O ensino de pediatria na atenção básica em saúde entre as fronteiras do modelo biomédico e a perspectiva da integralidade do cuidado: a visão dos médicos supervisores

Trata-se de estudo sobre educação médica, focalizado no ensino de pediatria na atenção básica, com o objetivo de analisar a contribuição da disciplina de Pediatria Social e Comunitária no 4º ano de graduação em medicina da Faculdade de Medicina de Botucatu, Universidade Estadual Paulista.Utilizou-se metodologia qualitativa de pesquisa, tendo como estratégia o estudo de caso. A análise foi fundamentada na abordagem sócio-histórica, subsidiada pelos estudos de Vigotski. Identificou-se o que os supervisores consideraram como aprendizados relevantes a sua contribuição no processo de mediação para que os estudantes aprendam sobre o processo de trabalho na atenção básica, o que não poderiam alcançar sozinhos. As entrevistas transcritas revelaram núcleos de significação comuns: importância da diversificação de cenários de ensino, aprendizado dos principais problemas de saúde, integralidade no atendimento da criança, com ênfase no vínculo e oportunidade do estudante aprender sobre promoção da saúde.

Sentimentos e percepções de puérperas com relação à assistência prestada pelo serviço materno-infantil de um hospital universitário

OBJETIVOS: avaliar percepções e sentimentos de puérperas adultas e adolescentes, relacionados ao filho e a assistência materno-infantil, em hospital universitário de nível terciário. MÉTODOS: estudo transversal, envolvendo 180 puérperas, no Alojamento Conjunto (AC) e no Berçário Interno (BI) do Hospital das Clínicas da Faculdade de Medicina de Botucatu , entrevistadas no segundo e terceiro dia pós-parto e distribuídas em três grupos: adultas primíparas, adultas multíparas e adolescentes. Para comparação entre grupos e locais de internação utilizou-se o chi2 ou teste de Fisher. RESULTADOS: ultrasom obstétrico e cardiotocografia tiveram impacto positivo na emoção materna. Houve pouca diferença entre os grupos quanto aos sentimentos antes e após o parto, sendo felicidade, amor, responsabilidade, ansiedade e medo os mais freqüentes. A culpa predominou nas adolescentes do BI. As percepções relacionadas ao filho, a avaliação da assistência e equipe, não diferiram entre adultas e adolescentes. Nas duas enfermarias o relacionamento entre mães e cuidadores foi bom, as mães mostraram-se satisfeitas com a equipe e a assistência, mas o aleitamento materno foi pouco valorizado e poucas mães conheciam o médico. CONCLUSÕES: está ocorrendo um processo de humanização na assistência materno-infantil deste hospital universitário, mas alguns aspectos precisam ser melhorados, especialmente a valorização do aleitamento materno e a individualização no contato médico-paciente.

Usefulness of catheter tip culture in the diagnosis of neonatal infections

Objective: To determine the number of colony-forming units (CFU) that best correlates with catheter-related infections (CRI) in newborns.Methods: This was a prospective study of semiquantitative cultures of catheter tips obtained from newborns in the neonatal unit at Faculdade de Medicina de Botucatu, state of São Paulo, Brazil. The microorganisms isolated from catheter and peripheral blood cultures were identified and submitted to a drug susceptibility test. The optimal cutoff point was determined by the receiver operating characteristic (ROC) curve.Results: A total of 85 catheters obtained from 63 newborns were studied. Staphylococcus epidermidis was the predominant species in the catheters (75%). Eight of 11 (72.7%) CRI episodes were associated with coagulase-negative staphylococci, six of which were of the S. epidermidis type. ROC curve analysis indicated that the optimal cutoff point for the diagnosis of CRI was 122 CFU.Conclusions: The cutoff point of 122 CFU correlated best with the diagnosis of CRI in newborns.

A function to predict the risk for death in the neonatal sepsis

This was a prospective study of 43 septic neonates at the NICU of the School of Medicine of Botucatu, São Paulo State University. Clinical and laboratory data of sepsis were analyzed based on outcome divided into two groups, survival and death. We calculated the discriminatory power of the relevant variables for the diagnosis of sepsis in each group, and using software for Discriminant Analysis, a function was proposed. There were 43 septic cases with 31 survivals and 12 deaths. The variables that had the highest discriminatory power were: n(o) of compromised systems, the SNAP, FiO2, and (A-a)O2. The study of these and others variables, such as birth weight, n(o) of risk factors, and pH using a Linear Discriminant Function(LDF) allowed us to identify the high-risk neonates for death with a low error rate (8.33%). The LDF was: F = 0.00043 (birth weight) + 0.30367 (n(o) of risk factors) - 0.1171 (n(o) of compromised systems) + 0.33223 (SNAP) + 2.27972 (pH) - 14.96511 (FiO2) + 0.01814 ((A-a)O2). If F > 22.77 there was high risk of death. This study suggests that the LDF at the onset of sepsis is useful for the early identification of the high-risk neonates that need special clinical and laboratory surveillance.

Perinatal factors associated with early deaths of preterm infants born in Brazilian Network on Neonatal Research centers

Objective: To evaluate perinatal factors associated with early neonatal death in preterm infants with birth weights (BW) of 400-1,500 g.Methods: A multicenter prospective cohort study of all infants with BW of 400-1,500 g and 23-33 weeks of gestational age (GA), without malformations, who were born alive at eight public university tertiary hospitals in Brazil between June of 2004 and May of 2005. Infants who died within their first 6 days of life were compared with those who did not regarding maternal and neonatal characteristics and morbidity during the first 72 hours of life. Variables associated with the early deaths were identified by stepwise logistic regression.Results: A total of 579 live births met the inclusion criteria. Early deaths occurred in 92 (16%) cases, varying between centers from 5 to 31%, and these differences persisted after controlling for newborn illness severity and mortality risk score (SNAPPE-II). According to the multivariate analysis, the following factors were associated with early intrahospital neonatal deaths: gestational age of 23-27 weeks (odds ratio - OR = 5.0; 95%CI 2.7-9.4), absence of maternal hypertension (OR = 1.9; 95%CI 1.0-3.7), 5th minute Apgar 0-6 (OR = 2.8; 95%CI 1.4-5.4), presence of respiratory distress syndrome (OR = 3.1; 95%CI 1.4-6.6), and network center of birth.Conclusion: Important perinatal factors that are associated with early neonatal deaths in very low birth weight preterm infants can be modified by interventions such as improving fetal vitality at birth and reducing the incidence and severity of respiratory distress syndrome. The heterogeneity of early neonatal rates across the different centers studied indicates that best clinical practices should be identified and disseminated throughout the country.

Could neonatal testosterone replacement prevent alterations induced by prenatal stress in male rats?

The present study was designed to examine whether testosterone replacement is able to prevent some effects of maternal restraint stress during the period of brain sexual differentiation - on endocrine system and sexual behavior in male rat descendants. Pregnant rats were exposed to restraint stress for 1 h/day from gestational days 18 to 22. At birth, some male pups from these stressed rats received testosterone propionate. The neonatal testosterone replacement was able to prevent the reduction in anogenital distance at 22 days of age observed in pups from stressed pregnant rats as well as prevents the decrease in testosterone levels during the adulthood of these animals. Testosterone replacement in these males also presented an improvement in sexual performance. In this way, testosterone replacement probably through increasing neonatal level of this hormone was able to prevent the later alterations caused by the prenatal stress during the period of brain sexual differentiation.

Effects of neonatal clomiphene citrate on fertility and sexual behavior in male rats

In order to investigate the participation of estrogen during the period of brain sexual differentiation, male rats were treated with clomiphene citrate in the neonatal phase. Fertility and sexual behavior were assessed during adult life. Sexual maturation, body weight, and wet weight of the testes were unchanged. Although the adult male rats treated with clomiphene in the neonatal phase presented a significant reduction in the frequency of mounts, 90% of these rats were able to mate with normal females, which became pregnant. However, these females exhibited a significantly increased number of pre- and post-implantation losses. When these adult male rats were castrated and received estrogen, 60% presented female sexual behavior (receptive behavior and acceptance of mount). Thus, treatment of pups with clomiphene immediately after birth has a long-term effect on the reproductive physiology and sexual behavior of male rats. (C) 2002 Elsevier B.V. All rights reserved.
