Abstract: O presente estudo tem por objetivo analisar a influência da irriga o da cavidade peritoneal com solu o de cloreto de sódio 0,9 % em ratos com peritonite fecal. Foram utilizados 36 ratos da linhagem Wistar, adultos ,machos ,pesando entre 160 e 210g. Estes animais foram alocados em três grupos iguais e submetidos a peritonite com homogeneizado de fezes humanas. No grupo I , o procedimento foi realizado para verificar a eficácia da peritonite fecal e todos os animais morreram após 24 horas da inje o intraperitoneal. Após 6 horas de evolu o da peritonite, os ratos do grupo II foram submetidos a laparotomia e irriga o cavidade abdominal com solu o de cloreto de sódio a 0,9 %. Neste grupo todos os animais permaneceram vivos após 48 horas da laparotomia. No grupo III, os ratos foram submetidos a laparotomia e limpeza da cavidade peritoneal com gaze estéril. Foi verificado que somente 6 ratos permaneceram vivos após 48 horas da laparotomia. O presente estudo demonstrou que a irriga o da cavidade peritoneal com solu o de cloreto de sódio a 0,9 % foi capaz de reduzir os índices de mortalidade em ratos com peritonite fecal.

Abstract: Institui es de Longa Permanência para Idosos (ILPI) s o estabelecimentos para atendimento integral, institucionalizando pessoas de 60 anos e mais, dependentes/ou n o, que n o disp em de condi es para permanecer com a família ou/em seu domicílio. A institucionaliza o pode desencadear doen as, dentre elas a depress o. Foi objetivo deste artigo de atualiza o fazer uma reflex o sobre a rela o do cuidado ao idoso deprimido e residente em ILPI com três princípios da Complexidade segundo Edgar Morin. Primeiro, se reflete sobre a complexidade; depois, se relaciona o cuidado ao idoso deprimido e residente em ILPI, com os princípios dialógico, recursivo e hologramático. Percebeu-se que a Complexidade pode sustentar teoricamente, n o só a compreens o do fen meno depress o no idoso residente em uma ILPI, como também inspirar o modo de cuidar que direcione aos trabalhadores da saúde, que atuam junto à pessoa idosa, a abordarem o idoso de forma mais global. Para tanto deve ser utilizada a Avalia o Multidimensional do Idoso, que analisa as várias dimens es da pessoa idosa, contribuindo no desenvolvimento de um plano de cuidado/tratamento e acompanhamento multidisciplinar e interdisciplinar adequados. A Complexidade vem sendo utilizada, por enfermeiros, para entender melhor a enfermagem e prestar cuidado mais adequado ao ser humano.

Abstract: PURPOSE: To evaluate the effects of positive end expiratory pressure and physiotherapy intervention during Phase I of cardiac rehabilitation on the behavior of pulmonary function and inspiratory muscle strength in postoperative cardiac surgery. METHODS: A prospective randomized study, in which 24 patients were divided in 2 groups: a group that performed respiratory exercises with positive airway expiratory pressure associated with physiotherapy intervention (GEP, n = 8) and a group that received only the physiotherapy intervention (GPI, n = 16). Pulmonary function was evaluated by spirometry on the preoperative and on the fifth postoperative days; inspiratory muscle strength was measured by maximal inspiratory pressure on the same days. RESULTS: Spirometric variables were significantly reduced from the preoperative to the fifth postoperative day for the GPI, while the GEP had a significant reduction only for vital capacity (P < .05). When the treatments were compared, smaller values were observed in the GPI for peak flow on the fifth postoperative day. Significant reductions of maximal inspiratory pressure from preoperative to the first postoperative day were found in both groups. However, the reduction in maximal inspiratory pressure from the preoperative to the fifth postoperative day was significant only in the GPI (P < .05). CONCLUSIONS: These data suggest that cardiac surgery produces a reduction in inspiratory muscle strength, pulmonary volume, and flow. The association of positive expiratory pressure with physiotherapy intervention was more efficient in minimizing these changes, in comparison to the physiotherapy intervention alone. However, in both groups, the pulmonary volumes were not completely reestablished by the fifth postoperative day, and it was necessary to continue the treatment after hospital convalescence.

Abstract: there is evidence that oxidative stress, defined as a persistent imbalance between the production of highly oxidative compounds and antioxidant defenses, leads to tissue damage. oxygen metabolism generates free radicals and/or non-radical reactive oxygen species. the mitochondria, through the electron transport chain, are the main generator of these species. the antioxidant defense system has the function of inhibiting and/or reducing the damage caused by the deleterious free radicals and/or non-radical reactive oxygen species. this system is divided into enzymatic (superoxide dismutase, catalase and glutathione peroxidase), and nonenzymatic. the nonenzymatic system consists of a variety of antioxidant substances, which may be endogenous or dietary. this study proposed to review the main mechanisms of reactive oxygen species generation and the role of the most relevant agents of the antioxidant defense system on the biomarkers of oxidative stress. the main exogenous factors that modulate oxidative stress will also be discussed.
