SURGICAL SHOCK 277 



be comparable to that which follows adrenalectomy. A long 

 period of etherization, protracted fevers, burns, etc. may pos- 

 sibly lead to such a state. However, in most cases of shock it 

 is difficult to see how the adrenals are implicated. Thus in 

 such injuries as crushing of the testicles or manipulation of the 

 intestines, it is unlikely that the adrenals should suddenly cease 

 secreting the vital cortical hormone, or, if they do, that the 

 supply of the hormone should be depleted so rapidly from the 

 body. It is more logical and in accord with the known facts 

 to attribute the shock which develops in such conditions to 

 nervous impulses from the site of injury which reflexly cause 

 a paralysis of the vasomotor system.
