Prevalence of psychoactive substance use by adolescents in public schools in a municipality in the São Paulo Metropolitan Area, Brazil.

This study aimed to estimate the prevalence of psychoactive substance use by adolescents from public schools. This is a cross-sectional study that used a random sample of adolescents from five public schools located in a municipality in the central-west region of the São Paulo Metropolitan Area, Brazil. Information on demographic, socioeconomic, and drug use was collected using self-report questionnaires. The sample consisted of 1,460 students, 716 (49%) males, aged 10-19 years (13.19±2.04 years). The prevalence of psychoactive substance use in the last month was 51% for analgesics; 48.8% for alcohol; 37.3% for tobacco; 30.8% for tranquilizers; 23.1% for marijuana; 22.6% for anabolic steroids; 21.6% for ecstasy; 15.3% for amphetamines/stimulants; 13.4% for phencyclidine; 12.9% for cocaine/crack; 12.6% for inhalants/solvents; 11.5% for opiates; 11.4% for hallucinogens; and 16.2% for other unclassified drugs. Elementary and middle school students were more likely to consume tobacco (OR = 2.306; 95%CI: 1.733-3.068; p < 0.001), and male students were more likely to consume any type of substance. We identified a high use of psychoactive substances among this study participants, with a higher prevalence among male students.

Spontaneous Orofacial Movements at Writhing and Fidgety General Movements Age in Preterm and Full-Term Infants.

BACKGROUND: As general spontaneous movements at the writhing and fidgety ages have been important for the early identification of neurodevelopmental impairment of both full-term and preterm infants, the knowledge of the spontaneous orofacial movements at these ages also seems to be important for the diagnosis of oral function, particularly in preterm infants. Therefore, we decided to first classify preterm and full-term infants according to general movements ages, and then to record, describe, compare, and discuss their spontaneous orofacial movements. METHODS: This cross-sectional study included 51 preterm infants (born between 28 and 36 weeks) and 43 full-term infants who were classified at the writhing and fidgety ages of Prechtl's method of general movements assessment. Their spontaneous orofacial movements were recorded on video, and The Observer XT software (Noldus) was used to record the quantitative values of the movements. RESULTS: Poor repertoires of writhing movements were more frequent in the preterm infants (90.9%) compared to full-term ones (57.9%). Positive fidgety movements were observed in 100% of both preterm and full-term infants. Oral movements were similar for both preterm and full-term infants, regardless of their movement stage. CONCLUSION: All spontaneous orofacial movements were present both in preterm and full-term infants, albeit with higher frequency, intensity, and variability at fidgety age.

Nutritional practices and postnatal growth restriction in preterm newborns / Práticas nutricionais e restrição de crescimento pós-natal em prematuros

SUMMARY Objective: to assess the nutritional practices in neonatal intensive care units (NICU) associated with growth retardation in premature (preterm) infants. Methods: retrospective study of preterm infants weighing between 500 and 1,499g admitted to NICU. Evolution of growth and parenteral (PN) and enteral (EN) nutrition practices were analyzed. Results: among 184 preterm infants divided into G1 (500 to 990g; n=63) and G2 (1000 to 1499g; n=121), 169 received PN (G1=63, G2=106). Compared with the recommendations, PN was started late, its progress was slow and the maximum glucose, amino acid, lipid and energy supplies were low in both groups. The initial supply of amino acid and lipid and initial and maximum glucose and energy were lower in G1. The onset of EN was early (1-2 days), the time to reach exclusive EN was appropriate (11-15 days) and the use of human milk was possible in a reasonable amount of time (7-13 days). The multivariate analysis showed that respiratory distress syndrome and obtaining a supply of 120 kcal/kg/day too late increased the chance of weight loss greater than 10%. Sepsis, maximum energy supply for PN <60 kcal/kg/day and obtaining a supply of 120 kcal/kg/day too late increased the chance of regaining birth weight after 14 days, while small for gestational age (SGA) at birth reduced this chance. SGA at birth, sepsis and achieving exclusive enteral nutrition after 14 days increased the chance of being SGA at post-conceptual age of term. Conclusion: improving nutritional practices in the NICU can reduce the growth deficit in premature infants of very low birth weight.

RESUMO Objetivo: avaliar as práticas nutricionais em unidade de cuidados intensivos neonatais (UCIN) associadas a déficit de crescimento em recém-nascidos pré-termo (RNPT). Métodos: estudo retrospectivo de RNPT com peso entre 500 e 1.499 g internados em UCIN. Analisaram-se: evolução do crescimento e práticas de nutrição parenteral (NP) e enteral (NE). Resultados: dentre 184 RNPT divididos em G1 (500 a 990 g; n=63) e G2 (1.000 a 1.499 g; n=121), 169 receberam NP (G1=63; G2=106). Comparando-se com as recomendações, a NP foi iniciada tardiamente, sua progressão foi lenta e as ofertas máximas de glicose, aminoácidos, lipídios e energia foram baixas nos dois grupos. A oferta inicial de aminoácido e lipídio e a inicial e máxima de glicose e energia foram menores no G1. O início da NE foi precoce (1 a 2 dias), o tempo para atingir NE exclusiva foi adequado (11 a 15 dias), e o uso de leite humano foi possível por tempo razoável (7 a 13 dias). A análise multivariada mostrou que a síndrome do desconforto respiratório e o alcance tardio da oferta de 120 kcal/kg/dia aumentaram a chance de perda de peso superior a 10%. Sepse, oferta energética máxima por NP < 60 kcal/kg/dia e alcance tardio da oferta de 120 kcal/kg/dia aumentaram a chance de recuperar o peso de nascimento após 14 dias, enquanto a condição de pequeno para idade gestacional (PIG) ao nascimento reduziu essa chance. PIG ao nascimento, sepse e alcance de NE exclusiva após 14 dias aumentaram a chance de ser PIG na idade pós-conceptual de termo. Conclusão: aprimorar as práticas nutricionais em UCIN pode reduzir o déficit de crescimento em prematuros de muito baixo peso ao nascer.

Pacientes com necessidades especiais - da regulamentação pública ao ensino odontológico / Patients with special needs - regulation of the public dental education

Objetivo ­ Analisar a educação odontológica em âmbito universitário voltada aos cuidados com pacientes portadores de necessidades especiais, considerando que tais indivíduos requerem cuidados especiais para atendimento odontológico por apresentarem uma ou mais limitações, temporárias ou permanentes, de ordem mental, física, sensorial e emocional, que os impedem de serem submetidos a atendimento convencional. Indivíduos com necessidades especiais constituem população heterogênea, que apresenta parcial ou completa dependência e cuja vulnerabilidade tende a torná-los suscetíveis a distúrbios bucais e a comorbidades passíveis de comprometer sua qualidade de vida. Esses pacientes necessitam de adaptações especiais para as práticas da vida diária. Preparo e qualificação profissional são essenciais para os serviços de saúde que atendem essa população. Métodos ­ Foi realizado levantamento bibliográfico acerca de como procede o ensino da disciplina de Pacientes Especiais nas Faculdades de Odontologia em nosso país, procurou-se identificar também, estudos nos quais políticas públicas foram empregadas, visando amplificar a disseminação desses conhecimentos academicamente. Resultados ­ Averiguou-se que a disciplina geralmente não é obrigatória na graduação e que quando a disciplina está presente, têm-se carga horária variável, por vezes insuficiente, existindo oferta de formação complementar em cursos paralelos. Conclusão ­ Concluiu-se que o atendimento odontológico a pacientes especiais exige aporte de conhecimentos específicos e que não há regularidade e garantia desses conhecimentos serem adquiridos na graduação, implicando que políticas públicas de acesso a serviços de saúde para pacientes especiais ofereçam programas de capacitação e aperfeiçoamento aos profissionais da Odontologia para atuação nesses serviços

Objective ­ To analyze the dental education in university environment geared to the care of patients with special needs, considering that such individuals require special care for dental care because they have one or more limitations, temporary or permanent mental order, physical, sensory and emotional, that prevent them from being subjected to conventional care. Individuals with special needs are heterogeneous population with partial or complete dependency and vulnerability which tends to make them susceptible to oral disorders and comorbidities likely to compromise their quality of life. These patients need special adaptations to the practices of everyday life. Preparation and professional training are essential to the health services that serve this population. Methods ­ literature review was conducted on how proceeds the teaching of Special Patients discipline in dental schools in our country, we tried to identify also studies in which public policies were applied, in order to amplify the spread of this knowledge academically. Results ­ An examination was that the discipline usually is not mandatory at graduation and when discipline is present, have been variable hours, sometimes insufficient, existing supply of additional training in parallel courses. Conclusions ­ It was concluded that dental care to patients requires special contribution of expertise and there is no guarantee regularity and such knowledge be acquired during their studies, implying that public policies of access to health services for special patients provide training and improvement programs to dental professionals to operate these services.

The training of neonatologists and the paradigms implied in their relationship with the parents of babies in the Neonatal Intensive Care Unit.

OBJECTIVE: To analyze and to interpret the psychological repercussions generated by the presence of parents in the Neonatal Intensive Care Unit for residents in Neonatology. METHODS: Study based on the psychoanalytic theory, involving a methodological interface with qualitative surveys in Health Sciences. Twenty resident physicians in Neonatology, from five public institutions of São Paulo state, responded to a single semi-structured interview. Based on several readings of the material, achieving the core of emergent meanings that would be significant to the object of the survey, six categories were elected for analysis and interpretation: parents' staying at the Neonatal Intensive Care Unit and its effects on the neonatologists' professional practice; communication of the diagnosis and what parents should know; impasses between parents and doctors when the diagnosis is being communicated; doctor's identification with parents; communication of the child's death and their participation in the interview. RESULTS: The interpretation of the categories provided an understanding of the psychic mechanisms mobilized in doctors in their relationships with the children's parents, showing that the residents experience anguish and suffering when they provide medical care and during their training process, and also that they lack psychological support to handle these feelings. CONCLUSIONS: There is a need of intervention in neonatologists training and education, which may favor the elaboration of daily experiences in the Unit, providing a less anguishing and defensive way out for young doctors, especially in their relationship with patients and parents.

Avaliação do neurodesenvolvimento de prematuros de muito baixo peso ao nascer entre 18 e 24 meses de idade corrigida pelas escalas Bayley III / Neurodevelopmental assessment of very low birth weight preterm infants at corrected age of 18-24 months by Bayley III scales

OBJETIVO: Avaliar a prevalência de atraso e fatores associados aos escores de desenvolvimento em crianças nascidas prematuras. MÉTODOS: Estudo transversal para avaliar o desenvolvimento por escalas Bayley III, incluindo-se prematuros de muito baixo peso de 18 a 24 meses de idade corrigida, acompanhados no Ambulatório de Prematuros da instituição. Excluíram-se: malformação congênita, síndrome genética, infecção congênita sintomática ao nascimento, surdez e cegueira. As variáveis numéricas foram comparadas por teste t de Student ou Mann-Whitney, e as categóricas, por qui-quadrado ou teste exato de Fisher. Para análise dos fatores associados aos escores de desenvolvimento, utilizou-se a regressão linear, considerando-se significante p < 0,05. RESULTADOS: Das 58 crianças avaliadas, quatro (6,9%) apresentaram alteração cognitiva; quatro (6,9%), motora; 17 (29,3%), de linguagem; 16 (27,6%), socioemocional; e 22 (37,9%), de comportamento adaptativo. À regressão linear múltipla, os fatores classe socioeconômica CDE (-13,27; IC95% -21,23 a -5,31) e dependência de oxigênio com 36 semanas de idade corrigida (-8,75; IC95% -17,10 a -0,39) diminuíram o escore cognitivo. A leucomalácia periventricular diminuiu o escore cognitivo (-15,21; IC95% -27,61 a -2,81), motor (-10,67; IC95% -19,74 a -1,59) e de comportamento adaptativo (-21,52; IC95% -35,60 a -7,44). O sexo feminino se associou ao maior escore motor (10,67; IC95% 2,77-12,97), de linguagem (15,74; IC95% 7,39-24,09) e socioemocional (10,27; IC95% 1,08-19,46). CONCLUSÕES: Prematuros de muito baixo peso apresentaram com maior frequência alterações na linguagem, comportamento adaptativo e socioemocional. As variáveis classe socioeconômica CDE, leucomalácia periventricular, displasia broncopulmonar e sexo masculino contribuíram para reduzir os escores de desenvolvimento.

OBJECTIVE: To evaluate the prevalence of delay and factors associated with neurodevelopmental scores in premature infants. METHODS: Cross-sectional study to assess the development by Bayley Scales III, including very low birth weight preterm infants aged 18 to 24 months who were under follow-up at the outpatient clinic for preterm infants. Congenital malformation, genetic syndrome, symptomatic congenital infection at birth, deafness, and blindness were excluded. Numerical variables were compared by Mann-Whitney or Student t test and categorical variables by chi-square or Fisher's exact test. Factors associated with developmental scores were analyzed by linear regression, and statistical significance level was established at p < 0.05. RESULTS: Out of the 58 children included, four (6.9%) presented cognitive delay, four (6.9%) motor, 17 (29.3%) language, 16 (27.6%) social-emotional and 22 (37.0%) adaptive-behavior delay. By multiple linear regression, the variables: social classes CDE (-13.27; 95%CI: -21.23 to -5.31), oxygen dependency at 36 weeks of corrected age (-8.75; 95%CI: -17.10 to -0.39) decreased the cognitive developmental score. Periventricular leukomalacia decreased the cognitive (-15.21; 95%CI: -27.61 to -2.81), motor (-10.67; 95%CI:-19.74 to -1.59) and adaptive-behavior scores (-21.52; 95%CI: -35.60 to -7.44). The female sex was associated with higher motor (10.67; 95%CI: 2.77 to 12.97), language (15.74; 95%CI: 7.39 to 24.09) and social-emotional developmental scores (10.27; 95%CI: 1.08 to 19.46). CONCLUSIONS: Very low birth weight preterm infants aged from 18 to 24 months of corrected age presented more frequently language, social-emotional and adaptive-behavior delays. The variables: social classes CDE, periventricular leukomalacia, bronchopulmonary dysplasia and male sex reduced the neurodevelopmental scores.

Bacterial sepsis in Brazilian children: a trend analysis from 1992 to 2006.

BACKGROUND: The objective of this study was to determine the epidemiology of hospitalized pediatric sepsis in Brazil (1992-2006) and to compare mortality caused by sepsis to that caused by other major childhood diseases. METHODS AND FINDINGS: We performed a retrospective descriptive study of hospital admissions using a government database of all hospital affiliated with the Brazilian health system. We studied all hospitalizations in children from 28 days through 19 years with diagnosis of bacterial sepsis defined by the criteria of the International Classification of Diseases (ICD), (Appendix S1). Based on the data studied from 1992 through 2006, the pediatric hospital mortality rate was 1.23% and there were 556,073 pediatric admissions with bacterial sepsis with a mean mortality rate of 19.9%. There was a case reduction of 67% over 1992-2006 (p<0.001); however, the mortality rate remained unchanged (from 1992-1996, 20.5%; and from 2002-2006, 19.7%). Sepsis-hospital mortality rate was substantially higher than pneumonia (0.5%), HIV (3.3%), diarrhea (0.3%), undernutrition (2.3%), malaria (0.2%) and measles (0.7%). The human development index (HDI) and mortality rates (MR) by region were: North region 0.76 and 21.7%; Northeast region 0.72 and 27.1%; Central-West 0.81 and 23.5%; South region 0.83 and 12.2% and Southeast region 0.82 and 14.8%, respectively. CONCLUSIONS: We concluded that sepsis remains an important health problem in children in Brazil. The institution of universal primary care programs has been associated with substantially reduced sepsis incidence and therefore deaths; however, hospital mortality rates in children with sepsis remain unchanged. Implementation of additional health initiatives to reduce sepsis mortality in hospitalized patients could have great impact on childhood mortality rates in Brazil.

Enamel defects in the complete primary dentition of children born at term and preterm.

PURPOSE: This study's purpose was to compare the frequency of enamel defects (ED) in the complete primary dentition (CDD) of term children (TC) and preterm children (PTC) and to analyze neonatal factors associated with ED in PTC. METHODS: The study group was formed by 45 PTC, cared for at the Follow-up Clinic for Preterm Children of the Federal University of São Paulo, Brazil. The control group included 46 school-children born at term. RESULTS: ED was more frequent in PTC (87%) than in TC (44%; P<.05). All 34 PTC with tracheal intubation at birth presented ED, showing a strong association between both. The variable was not included in the regression model. To analyze neonatal factors associated with ED in PTC, a model of logistic regression was adjusted. Malnutrition at term-corrected age increased the risk of ED in PTC 7.8 times. Opacity (white/cream) and hypoplasia (missing enamel) were frequent types of ED in this series. PTC and TC presented with high ED frequencies. CONCLUSIONS: The frequencies of enamel defects were elevated in term and preterm children, but were higher in the latter. Tracheal intubation was strongly associated with enamel defects, and extrauterine growth restriction significantly increased the risk for enamel defects in preterm children.

Impact of perinatal factors on growth deficits of preterm infants.

OBJECTIVE: To review perinatal factors associated with a growth deficit in preterm infants at a corrected age of one year. METHODS: Cohort study of preterm infants with a birth weight < 2,000 g. Percentiles and Z scores of body weight (W/A), length (L/A) and head circumference (HC/A) at one year of corrected age were calculated by using the Centers for Disease Control and Prevention curves. RESULTS: Among 303 preterm infants, the frequencies of measures below the 10th percentile (P10) and Z scores -2 were 43.2% and 24.4% for W/A, 22.1% and 8.6% for L/A and 15.8% and 4.6% for HC/A, respectively. Logistic regression analyses showed factors associated with higher odds for W/A < P10 were resuscitation at birth (1.8 times) and small for gestational age infants (3.0 times). In infants rated as small at full-term postconceptual age, the odds for W/A < P10 were 4.0 times as high in those with a birth weight between 1,000 and 1,499 g and 3.5 times as high in those > 1,500 g. As birth length was reduced, the odds for L/A < P10 increased, but this was not associated with birth weight. The odds for HC/A < P10 were 2.5 times as high in small for gestational age infants. In infants with a body weight < 1,000 g, the odds for HC/A < P10 were 4.4 times higher, compared with those between 1,000 g and 1,499 g and 5.3 times higher if compared with those > 1,500 g. CONCLUSION: At a corrected age of one year, preterm infants with a birth weight < 2,000 g were found with high growth deficits frequencies, and associated factors were variable, depending on the analyzed deficit, with intrauterine and postnatal growth restriction being outstanding predictors.

Impacto dos fatores perinatais nos déficits de crescimento de prematuros / Impact of perinatal factors on growth deficits of preterm infants

OBJETIVO: Analisar fatores perinatais associados a déficit de crescimento em prematuros com 1 ano de idade corrigida. MÉTODOS: Estudo de coorte de prematuros com peso ao nascer < 2.000 g. Calcularam-se os percentis e escores Z de peso (P/I), comprimento (C/I) e perímetro cefálico (PC/I) com 1 ano de idade corrigida, utilizando a curva do Centers for Disease Control and Prevention. RESULTADOS: Entre 303 prematuros, as frequências de medidas abaixo do percentil 10 (P10) e de -2 escores Z foram, respectivamente, 43,2 por cento e 24,4 por cento de P/I, 22,1 por cento e 8,6 por cento de C/I e 15,8 por cento e 4,6 por cento de PC/I. A análise de regressão logística mostrou que fatores associados à maior chance de P/I < P10 foram reanimação ao nascimento (1,8 vez) e pequeno para a idade gestacional (3,0 vezes). Nas crianças classificadas como pequenas na idade pós-conceptual de termo, a chance de P/I < P10 foi 4,0 vezes maior naquelas com peso ao nascer entre 1.000 g e 1.499 g e 3,5 vezes maior naquelas > 1.500 g. A chance de C/I < P10 aumentou com a diminuição do comprimento ao nascer, mas não associou ao peso ao nascer. A chance de PC/I < P10 foi 2,5 vezes maior nas crianças pequenas para a idade gestacional. Nas crianças com peso < 1.000 g, a chance de PC/I < P10 foi 4,4 vezes maior quando comparadas àquelas entre 1.000 g e 1.499 g e 5,3 vezes maior quando comparadas àquelas > 1.500 g. CONCLUSÃO: Com 1 ano de idade corrigida, prematuros nascidos com peso < 2.000 g apresentaram frequências elevadas de déficits de crescimento, e os fatores associados variaram com o déficit analisado, destacando-se a restrição de crescimento intrauterino e pós-natal.

Diphtheria, tetanus, and varicella immunity in health care workers in neonatal units.

BACKGROUND: Susceptible health care workers are at risk of acquiring and transmitting vaccine-preventable diseases to or from patients. The objective of this study was to assess antibody levels against diphtheria, tetanus, and varicella in healthcare workers. METHODS: Antibody levels against diphtheria, tetanus, and varicella were measured in health care professionals in 2 neonatal units at the Federal University of São Paulo, Brazil. RESULTS: Between September and November 2002, 215 of 222 (96.8%) health care workers were studied. Of those, 122 (56.7%) gave oral information regarding their vaccination status against diphtheria and tetanus and only 9 (4.2%) had their vaccination cards. Geometric mean antibody levels against diphtheria, tetanus, and varicella were 0.89 IU/mL (95%CI, 0.73 to 1.08), 0.86 IU/mL (95%CI, 0.68 to 1.07) and 1.10 IU/mL (95%CI, 0.98 to 1.24), respectively. Using internationally accepted definitions, 200 (93.0%) and 182 (84.7%) individuals had full protection against diphtheria and tetanus, respectively. Regarding varicella, 213 (99.1%) individuals were immune and 2 (0.9%) had equivocal immunity against varicella. Of 65 (30.2%) individuals without previous history of the illness, 63 (96.9%) were immune against varicella zoster virus. CONCLUSIONS: Based on serologic screening, most professionals were immune to diphtheria, tetanus, and varicella. Absence of previous history of varicella was an unreliable identifier of susceptibility to varicella zoster virus in the health care workers studied.

Chest expansion for assessing tidal volume in premature newborn infants on ventilators.

OBJECTIVES: To investigate whether clinical observation of chest expansion predicts tidal volume in neonates on mechanical ventilation and whether observer experience interferes with results. METHODS: An observational study that enrolled less experienced physicians in the first year of pediatric residency, moderately experienced (second year pediatric residency, first year of neonatology or pediatric intensive care specialization) or who were already experienced (second year neonatology specialization, graduate students or primary physician supervisors with minimum experience of 4 years in neonatology). These professionals observed the chest expansion of newborn infants on mechanical ventilation and estimated the tidal volume being supplied to the babies. True tidal volume given was calculated, indexed by the patient's current weight, and considered adequate between 4 and 6 mL/kg, insufficient below 4 mL/kg and excessive over 6 mL/kg. Results were analyzed using chi-square test. RESULTS: One hundred and eleven assessments were carried out with 21 newborn infants and the estimates given were in agreement with measured volume in 23.1, 41.3 and 65.7% for less, moderately and experienced physicians, respectively. These results are evidence that the three groups are not statistically equal (p = 0.013) and that the group of fully-experienced physicians have a better level of agreement than those with little or moderate experience (p = 0.007). CONCLUSIONS: Clinical analysis of chest expansion by physicians with less or moderate experience exhibit a low level of agreement with the tidal volume given to newborn infants on mechanical ventilation. Although increased experience did result in higher levels of agreement, chest expansion must still be interpreted with caution.

Expansibilidade torácica na avaliação do volume corrente em recém-nascidos prematuros ventilados / Chest expansion for assessing tidal volume in premature newborn infants on ventilators

OBJETIVOS: Avaliar se a observação clínica da expansibilidade torácica prediz o volume corrente em neonatos sob ventilação mecânica e se a experiência do examinador interfere no resultado. MÉTODOS: Estudo observacional que incluiu médicos de baixa experiência (1° ano de residência em pediatria), moderada experiência (2° ano de residência em pediatria, 1° ano de especialização em neonatologia ou em terapia intensiva pediátrica) e experientes (2° ano de especialização em neonatologia, pós-graduandos ou assistentes com experiência mínima de 4 anos em neonatologia). Estes observaram a expansibilidade torácica de recém-nascidos em ventilação mecânica e responderam qual o volume corrente fornecido aos bebês. O volume corrente ofertado foi calculado, indexado ao peso atual do paciente e considerado adequado se entre 4-6 mL/kg, insuficiente se abaixo de 4 mL/kg e excessivo se acima de 6 mL/kg. Para análise dos resultados, foi utilizado o qui-quadrado. RESULTADOS: Foram realizadas 111 avaliações em 21 recém-nascidos, e as respostas fornecidas concordaram com o volume mensurado em 23,1, 41,3 e 65,7 por cento para os médicos de baixa, moderada experiência e experientes, respectivamente. Esses resultados evidenciam que os três grupos não são estatisticamente iguais (p = 0,013) e que o grupo de médicos experientes apresenta maior concordância que os de baixa e moderada experiência (p = 0,007). CONCLUSÃO: A análise clínica da expansibilidade torácica realizada por médicos de baixa e moderada experiência apresenta pouca concordância com o volume corrente ofertado aos recém-nascidos em ventilação mecânica. Embora a experiência dos médicos tenha resultado em maior concordância, a expansibilidade torácica deve ser interpretada com cautela.

As representações maternas acerca do bebê que nasce com doenças orgânicas graves / The maternal representations about a baby who is born with serious organic diseases

O nascimento de um bebê com doenças orgânicas graves tem profundas implicações na constituição do vínculo inicial mãe-bebê. O objetivo desta pesquisa é a investigação das representações psíquicas maternas acerca desse nascimento. Este estudo qualitativo está fundamentado no campo teórico-psicanalítico. Foram realizadas entrevistas semi-estruturadas, individuais, com 11 mães no período de internação do bebê na Unidade de Terapia Intensiva Neonatal. Os dados obtidos foram submetidos ao método de análise de conteúdo e revelaram que o nascimento do bebê com alterações orgânicas afeta a função materna já que desorganiza as representações que eram antes dirigidas ao bebê sadio imaginado, marcando uma tendência recorrente à equivalência desse bebê ao diagnóstico de sua doença. Este nascimento implica, portanto, o luto pelo filho desejado e o decréscimo da auto-estima materna. A participação nas entrevistas teve efeitos terapêuticos, sugerindo a necessidade de uma escuta analítica dessas mães durante o período de permanência do bebê na instituição hospitalar.

The birth of a baby with serious organic diseases has deep implications in the constitution of the initial link mother-baby. This research aims at investigating the maternal psychic representations about this birth. This qualitative study is based on the psychoanalytic-theoretical field. Semi- structured individual interviews with 11 mothers were carried out during the period of the baby hospitalization in the neonatal ICU. The obtained data were submitted to the content analysis method and showed that the birth of the baby with organic disturbances affects the maternal role, as it disorganizes the representations that were directed before to the idealized healthy baby, marking a recurrent tendency to the equivalence of this baby with his/her disease diagnosis. This birth implies, therefore, in the mourning of the desired child and in the decrease of the maternal self-esteem. The participation in the interviews had therapeutical effects, suggesting the need of an analytycal listening of these mothers during the period the baby remains in the hospital.
