In a previous communication,1 the use of convalescent serum intramuscularly in the treatment of a small series of cases of early poliomyelitis was reported. Our purpose in this paper is to report the results of such treatment as employed in a series of eighty-one cases.
There is enough evidence2 at hand to support the view that convalescent serum has definite therapeutic usefulness in poliomyelitis. Most observers, however, have emphasized the value of using such serum intraspinally, with intravenous or intramuscular injection as a less valuable adjuvant. The late E. Charles Fleischner, on the other hand, insisted that on both theoretical and practical grounds the intramuscular route was to be preferred as a means of making the serum quickly and safely available to the early lesion.
