The effect of intra-aortic balloon pumping onthe coronary blood flow in hypothermia was studied in mongrel dogs.
IABP increased the coronary blood flow by 7% with 300 msec of deflate time in 3790, while it increased by 48 to 50% with 300 msec of deflate time in hypothermia.
These results were drived from a relative increase of the coronary blood flow in hypothermia.
It was concluded in our experiment that IABP was more effective in hypothermia than in normothermia.
