Abstract:
Objective To investigate the influences of hypothermia on hemodynamics and hemorrheology .Methods The body temperature of 10 mongrel dogs decreased at 35℃ ,and was kept for 30 min, and then warmed to normal degree with physical methods. The parameters of hemodynamics and hemorrheology were measured with the polygraph system (RM 6000, Nihon Kohden).Results Compared with the baselines, 30 min following hypothermia heart rate, mean arterial pressure, cardiac output, maximum rate of rise and decline of pressure(?dp/dtmax),cardiac index, left ventricular stroke work index were significantly reduced, while systemic peripheral resistance , blood viscosity were higher than those under normal body temperature (P
