No. of bitstreams: 1 437297.pdf: 2046103 bytes, checksum: 5e5e5750b4d41210e95d2b2b28b0eb22 (MD5) Previous issue date: 2011-10-31 / Background: there are few studies using animal models in chest physical therapy. However, there are no models to assess these effects in newborns. The objective of this study was to develop a model of atelectasis by bronchial obstruction in newborn pigs for the study of neonatal physiotherapy. Methods: 30 newborn pigs resulting from a cross-breeding between Large White and Landrace, properly sedated, anesthetized, tracheostomized, paralyzed and mechanically ventilated were used. Artificial mucus was instilled into the airways through an infusion pump 15 minutes after instrumentation. Radiological assessment of the lungs (in supine position) and blood gas analysis was performed 30 minutes after mucus infusion to confirm the production of atelectasis. Results: two radiologist not involved in this research analyzed X ray. The model showed consistent results between parameters of oxygenation and radiological analysis. The atelectasis model was successfully developed in over 70% of cases, surpassing 90% of attempts in the final phase of the study. Conclusions: this model of atelectasis showed results consistent enough to be tested in studies of chest physiotherapy techniques in newborns. / Introdu??o: existem poucos estudos utilizando modelos animais em fisioterapia respirat?ria. Al?m disso, n?o existem modelos para avaliar esses efeitos em rec?mnascidos. O objetivo deste estudo foi desenvolver um modelo de atelectasia por obstru??o br?nquica em porcos rec?m-nascidos, para o estudo das t?cnicas de fisioterapia respirat?ria neonatal. M?todos: foram utilizados 30 leit?es rec?m-nascidos, origin?rios de um cruzamento entre as ra?as Large-White e Landrace devidamente sedados, anestesiados, traqueostomizados, paralisados e colocados sob ventila??o mec?nica. Quinze minutos ap?s a instrumenta??o, os animais receberam infus?o de muco artificial atrav?s de bomba de infus?o. Transcorridos 30 minutos da infus?o de muco artificial os animais foram submetidos ? avalia??o radiol?gica do t?rax (em posi??o supina) e gasometria arterial para confirmar a produ??o de atelectasia. Resultados: as imagens radiol?gicas foram analisadas por dois radiologistas n?o envolvidos no estudo. O modelo apresentado mostrou consist?ncia de resultados entre os par?metros de oxigena??o e a an?lise radiol?gica. O modelo de atelectasia foi desenvolvido com sucesso em mais de 70% dos casos, ultrapassando 90% das tentativas na fase final do estudo. Conclus?es: este modelo de atelectasia apresentou resultados suficientemente consistentes para que possa ser testado em estudos sobre t?cnicas de fisioterapia respirat?ria em rec?m-nascidos.

No. of bitstreams: 1 438704.pdf: 1089872 bytes, checksum: 26e9b82adb7d51a185543e38c2cdc8d2 (MD5) Previous issue date: 2011-12-20 / BACKGROUND: Due to meconium's obstructive effect on the airways and its inhibitory action over the surfactant system, treatment with bronchoalveolar lavage and surfactant replacement are currently under evaluation. OBJECTIVE: To evaluate, in an experimental model, the effect on the arterial blood gases and pulmonary mechanics of the treatment of meconium aspiration syndrome with exogenous surfactant, preceded or not of bronchoalveolar lavage with diluted surfactant in low volumes. DESIGN/METHODS: 21 newborn piglets were mechanically ventilated with predetermined settings. Meconium aspiration syndrome was induced by instillation of 5 ml/kg of meconium 20% diluted in isotonic saline, and afterwards the piglets were randomly allocated to: group I (n=7) - control; group II (n=7) - surfactant (Curosurf?) 200mg/kg; group III (n=7) - bronchoalveolar lavage with diluted surfactant 5mg/ml (15 ml/kg in 2ml aliquots), followed by a supplementary dose of surfactant 125mg/kg. Arterial blood gases, compliance, resistance, and tidal volume were measured five times at specific intervals during the six hours of the study. RESULTS: After instillation of meconium, before treatment, the PaO2 fell to a mean of 50mmHg and the PaCO2 increased to 76mmHg (no statistically difference among groups). Mean PaO2 (mmHg) in groups I, II and III were 72, 106 and 172 (p=0,01); 70, 95 and 198 (p<0.01); 79, 110 and 217 (p=0.01) at 30 minutes, 3 and 6 hours after treatment, respectively. Mean PaCO2 (mmHg) in Groups I, II and III were 81, 65 and 35 (p=0.01); 82, 59 and 37 (p=0.01); 82, 75 and 32 (p<0.01) at 30', 3 and 6 hours after treatment, respectively. Mean Compliance (ml/cmH2O) in Groups I, II, III were 0.76, 1.01 and 1.57 (p<0.05); 1.02, 0.69, e 1.79(p<0.05) at 30 minutes and 6 hours after treatment, respectively. Mean resistance (cmH2O/L/S) in Groups I, II, III were 422.57, 385.29 and 268.86 (p<0.05); 408.83, 564.86 e 248.43(p<0.05) at 30 minutes and 6 hours after treatment, respectively. CONCLUSIONS: Bronchoalveolar lavage with diluted surfactant, with low volumes and small aliquots, followed by a supplementary dose of surfactant, significantly improved arterial blood gases and pulmonary function measurements when compared to the administration of a single dose of surfactant in an experimental model of meconium aspiration syndrome. / INTRODU??O: devido ao efeito obstrutivo do mec?nio nas vias a?reas e a a??o inibit?ria sobre o sistema surfactante, o lavado broncoalveolar e a reposi??o de surfactante est?o sendo avaliados nos ?ltimos tempos para o tratamento da s?ndrome da aspira??o de mec?nio. OBJETIVO: Avaliar, em modelo experimental, o efeito sobre os gases sangu?neos arteriais e a mec?nica pulmonar do tratamento da s?ndrome de aspira??o de mec?nio grave com surfactante ex?geno, precedido ou n?o de lavado broncoalveolar com surfactante dilu?do em pequenos volumes. M?TODOS: 21 porcos rec?m-nascidos eram ventilados mecanicamente com par?metros respirat?rios predeterminados. Para induzir a s?ndrome de aspira??o de mec?nio foi instilado 5ml/kg de mec?nio dilu?do a 20% em solu??o salina isot?nica. Ap?s, os porcos foram randomizados em 3 grupos: grupo I (n=7) - controle; grupo II (n=7) - surfactante (Curosurf?) 200mg/kg; grupo III (n=7) - lavado broncoalveolar com surfactante dilu?do 5mg/ml (15ml/kg em al?quotas de 2ml) seguido de uma dose suplementar de surfactante 125mg/kg. Gases arteriais sangu?neos, complac?ncia, resist?ncia e volume corrente foram avaliados durante as 6 horas do estudo em 5 momentos espec?ficos. RESULTADOS: ap?s a instila??o de mec?nio, antes do tratamento, a PaO2 caiu para uma m?dia em torno de 50mmHg e a PaCO2 aumentou para uma m?dia em torno de 76mmHg, n?o havendo diferen?a significativa entre os grupos. Ap?s o tratamento a m?dia da PaO2(mmHg) nos grupos I, II e III aos 30 minutos, 3 e 6 horas foi de 72, 106 e 172 (p=0,01) - 70, 95 e 198 (p<0,01) e 79, 110 e 217 (p=0,01), respectivamente. A m?dia da PaCO2 (mmHg) nos grupos I, II e III foi 81, 65 e 35 (p=0,01) - 82, 59 e 37 (p=0,01) e 83, 75 e 33 (p<0,01), respectivamente. Ap?s o tratamento a m?dia da complac?ncia (ml/cmH2O) aos 30 minutos e 6 horas nos grupos I, II, III foi de 0,76, 1,01 e 1,57(p<0,05) e de 1,02, 0,69 e 1,79 (p<0,05), respectivamente. A m?dia da resist?ncia (cmH2O/L/S) nos grupos I, II e III foi de 422,57, 385,29 e 268,86(p<0,05) e de 408,83, 564,86 e 248,43 (p<0,05) aos 30 minutos e 6 horas, respectivamente. CONCLUS?O: o lavado broncoalveolar com surfactante dilu?do, com baixos volumes e pequenas al?quotas, seguido por uma dose suplementar de surfactante, melhorou significativamente os gases sangu?neos arteriais e a mec?nica pulmonar quando comparado com uma dose de surfactante sem lavado broncoalveolar e com um grupo controle, em um modelo experimental de s?ndrome de aspira??o de mec?nio.

No. of bitstreams: 1 462202.pdf: 271710 bytes, checksum: 0bb3eea802f7b7cbfe9afa63458065c7 (MD5) Previous issue date: 2014-08-18 / Importance: Many efforts have ocurred in identify risk factors and causes of congenital syphilis (CS) persistence along years, and in many cases, the repetition of the condition in the same woman. In Rio Grande do Sul, there are no studies about the reincidence of CS, its causes and outcomes. Objectives: To investigate the next pregnancies in women who already had syphilis in a previous pregnancy. Methods: The study sample were women with obstetrical events ocurred in S?o Lucas Hospital (SLH) between may 1997 and december 2004. We included all patients with syphilis before or during pregnancy who had newborns, stillborns or abortions with CS, as patients correctly treated for syphilis before delivery and that had newborns without syphilis. The CS cases were defined according to the Brazilian Ministry of Health (appendix 1). The follow-up period for the subsequent pregnancies was until december 2011. The data were analised in program Epi Info 3.4, using the &#967;? test or Fisher exact test for associations, and Mann-Whitney-Wilcoxon test for comparison of medians. The level of significance was set at p < 0,05. Results: We identified 450 women with positive tests for syphilis that had at least one obstetrical event in SLH between may 1997 and december 2004, within 166 had at least one more obstetrical event in the same hospital until december 2011.Cases of CS were 82% in the initial events and 68,5% in the subsequent s (OR 2,09, CI95% 1,3-3,3). Within patients with CS in the initial event, 72% had at least one more pregnancy with CS, against 56,6% of patiens without CS in the initial event(OR 1,97, CI95% 0,9-4,4). Conclusions: Many cases of CS with adverse outcomes ocurred in the subsequent pregnancies, although less than in the initial events. It is suspected that more uninfected newborns may have been defined as cases of congenital syphilis in subsequent pregnancies, because of the lack of records of maternal history and the absence or inadequacy of prenatal care. It is important to increase surveillance on women who have already had one pregnancy with syphilis. / Import?ncia: Muitos esfor?os t?m ocorrido em identificar os fatores de risco e as causas da persist?ncia da s?filis cong?nita (SC) ao longo dos anos, e muitas vezes a repeti??o de casos em uma mesma mulher. No Rio Grande do Sul, ainda n?o existe um estudo sobre a reincid?ncia da SC, suas causas e seus desfechos. Objetivos: Investigar as gesta??es subsequentes em mulheres que tiveram s?filis na gesta??o. Material e m?todos: A popula??o de estudo foram as pacientes atendidas no Centro Obst?trico do HSL cujos eventos obst?tricos ocorreram entre maio de 1997 e dezembro de 2004. Foram inclu?das todas as pacientes que tiveram s?filis antes ou durante a gesta??o e tiveram rec?m-nascidos vivos, abortos ou natimortos com s?filis cong?nita, assim como pacientes adequadamente tratadas para s?filis antes do parto, que deram ? luz rec?m-nascidos vivos sem s?filis cong?nita. Os casos de s?filis cong?nita foram definidos conforme os crit?rios do Minist?rio da Sa?de (anexo 1). O levantamento das gesta??es subsequentes incluiu o per?odo at? dezembro de 2011. Os dados foram analisados no programa Epi Info 3.4, utilizando-se o teste de &#967;? ou teste exato de Fisher para associa??es, e o teste Mann-Whitney-Wilcoxon para compara??es de medianas. O n?vel de signific?ncia foi estabelecido como p < 0,05. Resultados: Foram identificadas 450 mulheres com testes positivos para s?filis com pelo menos um evento obst?trico no HSL entre maio de 1997 e dezembro de 2004, das quais 166 tiveram pelo menos mais um evento subsequente no mesmo hospital at? dezembro de 2011. Os casos de SC foram de 82% nos eventos iniciais e 68,5% nos subsequentes (OR 2,09, IC95% 1,3-3,3). Entre as pacientes com SC no evento inicial, 72% tiveram pelo menos mais um evento com SC, contra 56,6% das pacientes sem SC no evento inicial (OR 1,97, CI95% 0,9-4,4). Conclus?es: Ocorreram muitos de casos de SC com desfechos adversos nas gesta??es subsequentes, embora em menor n?mero do que nas iniciais. Suspeita-se que mais rec?m-nascidos n?o infectados possam ter sido definidos como casos de s?filis cong?nita nas gesta??es subsequentes, em virtude da falta de registros dos antecedentes maternos e da aus?ncia ou inadequa??o do acompanhamento pr?-natal. ? importante aumentar a vigil?ncia sobre as mulheres que j? tiveram uma gesta??o com s?filis.

Small doses of colostrum are administered to the oral mucosa and upper respiratory tract of the infant, which may exert a protective effect on the mucosal membrane. In addition, immunoglobulin A, colostrum cytokines, antioxidant agents and all anti-infective agents may interact with lymphoid cells within the oropharynx, stimulating the infant's immune function. Recently, studies have reported the importance of colostrum administered by the oropharyngeal route, especially for extremely low birth weight preterm infants, with nutritional and immune defense effects already demonstrated. The more premature the baby, the more it will benefit from early exposure to colostrum. OBJECTIVE: To estimate the success rate after implantation of a colostrum administration protocol in low birth weight preterm infants at the Hospital Sa?de, in Caxias do Sul, RS. METHODOLOGY: The study took place between March and July 2017, after the ethical approval of the project. The participants were 41 mother / baby pairs whose mothers, after signing the free and informed consent, made attempts to exhaust the breast to provide colostrum to their children. Preterm infants between 24 and 32 weeks of age who had an indication of colostrum therapy prescribed by the physician were included, and attempts were made to exhaust the breast before six hours of the newborn's life. Two data collection instruments created by the researcher were used, one with information about mothers and newborns and the other for the Neonatal Intensive Care Unit nursing team to respond. After the observation of the attempt to obtain the colostrum, the questions of the collection instrument were considered, as if the puerpera managed to exhaust 0.2 mL of colostrum or not, or if the breast was exhausted before six hours. Through the charts of each baby, the data on administration were collected. It was observed if there was a decrease in oxygen saturation and / or an increase in respiratory and cardiac frequencies at the time of administration of colostrum. The success of colostrum therapy was considered to be the administration of at least one dose of colostrum within the first 72 hours of life, and the success rate was reported as a percentage of the cases that were successful among all included. RESULTS: Among the 41 premature infants included in the protocol, 19 (46.3%) received at least one dose of colostrum within the first 72 hours of life and 22 (53.7%) did not receive colostrum. There was an association between being able to deplete the breast earlier and the baby to be able to receive colostrum, regardless of when it was received. All 22 cases of colostrum failure were due to failure to obtain colostrum within 72 hours postpartum. There was no association between whether or not colostrum could be collected and maternal age or gestational age. There were no adverse events, such as alterations in the respiratory and cardiac frequencies or decrease in oxygen saturation, in the 19 infants who received oropharyngeal colostrum. Regarding the perception of the professional care team about colostrum therapy, more than half reported being partially knowledgeable about the practice and only one felt totally knowledgeable. However, most of the care team (83.4%) reported being satisfied, very satisfied or totally satisfied with the implementation of the colostrum protocol. CONCLUSIONS: In general, this study demonstrated difficulties in the implantation of the protocol of colostrum therapy to premature infants at Hospital Sa?de in Caxias do Sul. The obstacles to the success of a protocol of colostrum therapy were revealed, which mainly resided in the fact that the puerperae had difficulty in exhausting the breast in the first few days after preterm birth, and as a consequence, most newborns were unable to receive maternal colostrum within the first three days of life. In successful cases, the mother's satisfaction with the fact that the child received her colostrum was rewarding. There was a insufficient deepening in the training of the professional care team. These results brought important data that can be used in the execution of a new protocol, in the same unit as well as in other units with the same characteristics. Additional studies should be performed to reveal ways to achieve better success in the application of colostrum therapy protocol, supplanting the difficulties of early breast exhaustion, and can thus benefit from the administration of oropharyngeal colostrum to premature infants. / INTRODU??O: A colostroterapia, tamb?m chamada de terapia imunol?gica oral, ? a administra??o do colostro por via orofar?ngea para rec?m-nascidos prematuros e pode ser iniciada nas primeiras seis horas de vida. S?o administradas pequenas doses de colostro na mucosa oral e trato respirat?rio superior do rec?m-nascido, o que poder? exercer efeito protetor sobre a membrana da mucosa. Al?m disso a imunoglobulina A, as citocinas colostrais, os agentes antioxidantes e todos os agentes anti-infecciosos podem interagir com c?lulas linfoides dentro da orofaringe, estimulando a fun??o imunol?gica do beb?. Recentemente estudos relatam a import?ncia do colostro administrado pela via orofar?ngea, principalmente para o prematuro de extremo baixo peso, com efeitos nutricionais e de defesa imunol?gica j? demonstrados. Quanto mais prematuro o beb?, mais ele se beneficiar? da exposi??o precoce ao colostro. OBJETIVO: Estimar o ?ndice de sucesso ap?s a implanta??o de um protocolo de administra??o de colostro em rec?m-nascidos prematuros de baixo peso, no Hospital Sa?de, em Caxias do Sul/RS. METODOLOGIA: O estudo ocorreu entre mar?o e julho de 2017, ap?s a aprova??o ?tica do projeto. Os participantes foram 41 pares m?e/beb? cujas m?es, ap?s assinatura do consentimento livre e esclarecido, fizeram tentativas de esgotar a mama para prover colostro aos seus filhos. Foram inclu?dos prematuros entre 24 e 32 semanas que tinham indica??o de colostroterapia, prescrita pelo m?dico, sendo iniciadas as tentativas de esgota da mama antes das seis horas de vida do rec?m-nascido. Utilizaram-se dois instrumentos de coleta de dados criados pela pesquisadora, um com informa??es sobre as m?es e sobre os rec?m-nascidos e o outro para a equipe de enfermagem da Unidade de Terapia Intensiva Neonatal responder. Ap?s a observa??o da tentativa de se esgotar ou n?o o colostro, foram contempladas as quest?es do instrumento de coleta, como se a pu?rpera conseguiu esgotar 0,2 mL de leite ou n?o, ou se conseguiu esgotar a mama antes das seis horas. Atrav?s do prontu?rio de cada beb?, foram coletados os dados sobre a administra??o. Observou-se se houve queda de satura??o de oxig?nio e/ou aumento das frequ?ncias respirat?ria e card?aca na hora da administra??o da colostroterapia. Considerou-se como sucesso da colostroterapia a administra??o de pelo menos uma dose de colostro dentro das primeiras 72 horas de vida, sendo o ?ndice de sucesso referido como porcentagem dos casos que obtiveram sucesso entre todos os inclu?dos. RESULTADOS: Entre os 41 prematuros inclu?dos no protocolo, 19 (46,3%) receberam pelo menos uma dose de colostro dentro das primeiras 72 horas de vida e 22 (53,7%) n?o receberam a colostroterapia. Houve associa??o entre conseguir esgotar a mama mais precocemente e o beb? conseguir receber a colostroterapia, independentemente do momento em que a recebeu. Todos os 22 casos de insucesso da colostroterapia se deveram ? n?o obten??o de colostro dentro das 72 horas p?s-parto. N?o houve associa??o entre o fato de conseguir ou n?o coletar o colostro e a idade materna, ou a idade gestacional. N?o houve nenhum evento adverso, como altera??o nas frequ?ncias respirat?ria e card?aca ou diminui??o da satura??o de oxig?nio, nos 19 RN que receberam colostro por via orofar?ngea. Em rela??o ? percep??o da equipe assistencial quanto ? colostroterapia, mais da metade referiu ser conhecedor parcial da pr?tica e apenas um sentia-se totalmente conhecedor. Entretanto, a maior parte da equipe assistencial (83,4%) referiu estar satisfeita, muito satisfeita ou totalmente satisfeita com a implanta??o do protocolo da colostroterapia. CONCLUS?ES: Em geral, este estudo demonstrou dificuldades na implanta??o do protocolo de colostroterapia a prematuros no Hospital Sa?de de Caxias do Sul. Foram revelados os empecilhos para o sucesso de um protocolo de colostroterapia, os quais residiram principalmente no fato de que as pu?rperas tiveram dificuldade em esgotar a mama nos primeiros dias ap?s o parto prematuro e, como consequ?ncia, a maioria dos rec?m-nascidos n?o conseguiu receber o colostro materno dentro dos primeiros tr?s dias de vida. Nos casos de sucesso, a satisfa??o da m?e pelo fato do filho receber o seu colostro foi compensadora. Faltou maior aprofundamento no treinamento da equipe assistencial. Os resultados trouxeram dados importantes que podem ser aproveitados na execu??o de um novo protocolo, na mesma unidade, assim como em outras unidades com as mesmas caracter?sticas. Estudos adicionais devem ser realizados para revelar formas de obter melhor sucesso na aplica??o do protocolo de colostroterapia, suplantando as dificuldades da esgota precoce da mama, podendo assim auferir os benef?cios da administra??o de colostro por via orofar?ngea aos prematuros.
