Abstract:
An irreversible hemorrhagic shock model was produced on dog. The effect of external counterpulsation on systemic circulation and microcireulation was observed by using a model CN-1821 colour microscopic TV set (Hitachi Denshia Ltd.) and a YKMICAS multiple parameters computer analysis system of microcirculation image. It was shown that 10 min after external counterpulsation treatment the decreased central venous pressure and mean arterial pressure during hemorrhagic shock rose and 120 min after treatment the microcirculatory disorder of conjunctiva in shock state, including vessel diameter, blood velocity, and blood flow, nearly returned to normal. Half of the animals survived more than 3 days. These results indicated that the application of external counterpulsation could improve the circulatory disturbance markedly in hemorrhagic shock, which led to increased survival rate.
