Perda de calor determinada pela exposição das alças intestinais em ratos

Abstract: RESUMO: Objetivo: Esta pesquisa tem por objetivo quantificar a perda de energia calórica que ocorre ao realizarmos uma laparotomia com exposição de alças intestinais à atmosfera em ratos; determinar a perda termodinâmica representada por watts/m² em função da superfície peritoneal exposta do animal e discutir meios de tratamento para a perda de calor. Método: Foram utilizados 30 ratos machos, Wistar, distribuídos em cinco grupos de seis animais cada, com idade de 8 a 9 semanas, com o peso entre 200 e 220g. No … Show more

“…Estima-se a incidência de 2 a 8% de sepse pós-esplenectomia na faixa etária pediátrica. Para adultos, a incidência de infecções graves situa-se entre 2,9 e 8,3% 5,8 . A mortalidade global da sepse pósesplenectomia situa-se entre 50 e 75% 4,5,7,8 .…”

“…These thermocouples are small (1 mm), rapidly respond to changes in temperature, and have high sensitivity. (2) Not being saturated and having a temperature lower than 37 °C, the air entering the system would, upon being heated, absorb water and decrease the calibration levels of the components of the device. (23) Therefore, we created the humidifier that would saturate the air at 100% upon its entering the system.…”

“…(1) During surgical procedures, the human organism is submitted to anesthesia, which inhibits the thermoregulatory mechanisms of the organism, and, if the ambient temperature is not maintained above a certain level, patients can develop hypothermia and suffer the potential consequences. (2)(3)(4)(5)(6)(7)(8) Hypothermia has deleterious effects on the organism, such as alterations in the basal metabolism, in oxygen transport, in carbon dioxide transport, and in serum concentration of hydrogen, as well as electrolyte and hormonal changes. (1,2,(9)(10)(11) The respiratory system is responsible for conditioning the air in the respiratory tract, which is vitally important for respiration and maintenance of homeothermy.…”

“…Considering that clinical criteria such as coloring, peristalsis, pulse's presence in marginal arcades and sectioned edges' bleeding may be failure in up to 60% 3 , several methods more objective, have been used to predict intestinal viability as: injection of radioactive microspheres using technetium 99 4,5 ; coloring intravascular injection 6,7,8,9,10,11,12 ; ultrasound Doppler 13 ; ultrasound laser Doppler 14,15,16,17,18 ; intestinal electromyography 19,20,21,22,23 ; and surface oximetry 3,24,25,26,27 . These methods have been experimentally applied as intestinal viability indicators, however none has achieved widespread clinical use.…”
