Effects of mild hypothemia on hemodynamics of systemic and renal of dog with septic shock

To explore the effects of mild hypothemia on hemodynamics of systemic and renal of dog with septic shock. 40 healthy dogs were randomly and evenly divided into the normal temperature non-infected group (NTNS), normal temperature infected group (NTS), hypothermia non-infected group (MHNS) and hypothermia infected group (MHS). NTS and MHS were pumped through the femoral vein of Escherichia coli (E.coli 1 × 10⁹ cfu/ml) by 0.5 ml·kg⁻¹·h⁻¹, producting septic shock model with high-power cycle. Combining with blood pump devices and low temperature thermostat bath, the MHNS and MHS implemented extracorporeal blood cooling method to maintain the blood in temperature (33 ± 1) °C. 0, 24, 48, 72 h point, tested specimens from femoral vein for renal function. In the 0-72 h. Pulse indicates the continuous cardiac output monitor (PiCCO) monitored systemic hemodynamics on each time point. In the 0-72 h, color Doppler ultrasound (CDFI) measured renal hemodynamic on each time point. There was an increase of SBP (P
