ABSTRACT
PURPOSE: To evaluate and describe immediate effects of the infusion of saline solution heated by SAF in bitches submitted to halothane anesthesia. METHODS: Thirteen bitches were employed and submitted to elective ovariohysterectomy in acclimatized operating room at 22 degrees C, allocated in two groups: GI, which received non-heated fluid and GII, which received fluid heated at 37 degrees C by SAF. The following parameters were evaluated in 30-minutes intervals (M0, M30, M60 and M90): rectal and cutaneous temperatures (TR and TC), cardiac and respiratory frequencies (HR and ), mean arterial blood pressure (MAP), serum concentration of urea, creatinin, serum activities of alanin aminotranspherasis (ALT), alkaline phosphatasis (ALP) and also hypnosis parameters. RESULTS: There were no significant alterations on clinical and biochemical, but there was group effect on mean arterial blood pressure, urea, ALT, ALP and hypnosis parameters. CONCLUSION: The isolated use of Fluid Heating System (SAF) was not enough to avoid hypothermia or lead to significant clinical and biochemical alterations in bitches submitted to halothane anesthesia.

PURPOSE: To evaluate and describe immediate effects of the infusion of saline solution heated by SAF® in bitches submitted to halothane anesthesia. METHODS: Thirteen bitches were employed and submitted to elective ovariohysterectomy in acclimatized operating room at 22ºC, allocated in two groups: GI, which received non-heated fluid and GII, which received fluid heated at 37ºC by SAF®. The following parameters were evaluated in 30-minutes intervals (M0, M30, M60 and M90): rectal and cutaneous temperatures (TR and TC), cardiac and respiratory frequencies (HR and ), mean arterial blood pressure (MAP), serum concentration of urea, creatinin, serum activities of alanin aminotranspherasis (ALT), alkaline phosphatasis (ALP) and also hypnosis parameters. RESULTS: There were no significant alterations on clinical and biochemical, but there was group effect on mean arterial blood pressure, urea, ALT, ALP and hypnosis parameters. CONCLUSION: The isolated use of Fluid Heating System (SAF®) was not enough to avoid hypothermia or lead to significant clinical and biochemical alterations in bitches submitted to halothane anesthesia.
OBJETIVO: Avaliar e descrever os efeitos imediatos da infusão de solução salina 0,9 por cento aquecida pelo SAF® sobre cadelas sob anestesia inalatória. MÉTODOS: Foram utilizadas 13 cadelas submetidas a ovariohisterectomia eletiva em centro cirúrgico climatizado a 22ºC, divididas em dois grupos: GI, que recebeu fluido em temperatura ambiente e GII, que recebeu fluido aquecido a 37ºC pelo SAF®. Os parâmetros clínicos avaliados em intervalos de 30 minutos (M0, M30, M60 e M90) foram: temperatura retal (TR) e cutânea (TC), freqüências cardíaca (FR) e respiratória (), pressão arterial média (PAM), tempo de hipnose, concentrações séricas de uréia e creatinina e atividades das enzimas séricas alanina aminotransferase (ALT) e fosfatase alcalina (ALP). RESULTADOS: Não foram evidenciadas alterações clínicas e bioquímicas significativas, mas houve efeito de grupo sobre as variáveis PAM, uréia, ALT, ALP e tempo de hipnose. CONCLUSÃO: O uso isolado do Sistema de Aquecimento de Fluidos (SAF®) não foi suficiente para evitar o estabelecimento da hipotermia em cadelas submetidas a anestesia geral inalatória, ou promover alterações clínicas e bioquímicas significativas.
