ABSTRACT

A solução hipertônica de cloreto de sódio 7,5 por cento (SSH) é eficaz em restaurar os parâmetros hemodinâmicos e reduzir a inflamação em modelos experimentais de choque hemorrágico. Assim, foi nosso objetivo investigar a ação da SSH sobre os mecanismos envolvidos na lesão de isquemia e reperfusão (I/R) em um modelo de choque hemorrágico controlado. Ratos Wistar (280-350 g) foram submetidos à hemorragia controlada, mantendo-se a pressão arterial média em 40 mmHg por 1 h / Hypertonic saline solution (HSS - NaCI 7,5 per cent) was shown to restore hemodynamic parameters in hemorrhagic shock and to decrease the inflammation triggered by ischemia-reperfusion injury (I/R). Therefore, our objective was to investigate the effects of HSS on the mechanisms involved in I/R, in an experimental model of controled hemorrhagic shock. Wistar rats (2`80-350 g) were submitted to the controled bleeding, keeping the mean arterial pressure around 40 mmHg, for 1 hour...
