Effects of spinal needle type on lateral distribution of 0.5% hyperbaric bupivacaine.

abstract：:The direct effect of protamine sulfate upon myocardial inotropism was studied using an isolated canine heart muscle preparation. Isometric force (F) was decreased to 87.6 +/- 1.2% of control values by a concentration of 50 x 10(-3) g/L protamine, which is approximately equal to the estimated serum concentration of pro...
