Current evidence does not support the use of fasciotomy or dermotomy following North American Crotalinae envenomation with elevated intracompartmental pressures. 
A new case report of a 17-month old bitten by a copperhead snake reinforces that early and adequate administration of crotaline Fab antivenin is the treatment of choice. 
Many experts recommend against measuring compartement pressures altogether; we know it will be elevated.
