Abstract:
Objective To investigate the effects of different temperature seawater immersion on the hemodynamic of traumato-hemorrhagic shock rats. Methods 40 male traumato-hemorrhagic shock rats were utilized in this experiment. The hemodynamic parameters were determined in rats at preshock, shock, 10min, 30min, 1h, 3h, 5h after immersion in 15℃, 21℃ and 31℃ seawater respectively. Results The hemodynamic parameters of rats immersed in 21℃ seawater were markedly decreased compared with those of land control group. The hemodynamic parameters of rats immersed in 15℃ seawater rapidly decreased as compared with other groups. After 1 hour immersed in 15℃ seawater, the MAP, HR, ?dpdtmax of traumato-hemorrhagic shock rats were significantly decreased (P
