Don’t perform fasciotomy in patients with snake envenomation absent direct measurement of elevated intracompartmental pressures.
Crotalinae snakebites produce findings mimicking compartment syndrome that are rarely indicative of actual compartment syndrome. Myonecrosis results from venom toxicity rather than elevated compartment pressures. Fasciotomy does not prevent, and may worsen, necrosis. In some cases with elevated compartment pressures, treatment with antivenom and without fasciotomy was successful. No available evidence indicates when fasciotomy should be performed in the management of snakebites. If considered, fasciotomy should not be performed without first documenting elevated compartment pressure.

How The List Was Created
The American College of Medical Toxicology’s (ACMT’s) Board of Directors established a Choosing Wisely® work group in 2013 to develop a list of items for the Choosing Wisely® campaign. Members of the work group were chosen to represent various practice settings within the field of medical toxicology, including ambulatory, acute and population-based practice. Work group members included the President of the College, the Chair of the Practice Committee, the Chair of the Positions and Guidelines committee and other academic leaders within the medical toxicology community. All work group members also represented the American Academy of Clinical Toxicology (AACT). The first list was released by the work group in 2013 and in 2014, the work group reconvened to develop a second list of items for the campaign. A second preliminary list was disseminated to all members of ACMT and AACT for review, commentary and potential additions. Additional feedback was solicited from leaders within the field of medical toxicology. The work group reviewed all responses, and narrowed the list to the final five items based on a review of scientific evidence, relevance to the specialty and greatest opportunity to improve care, reduce cost and reduce harm to patients.The final list was approved by the ACMT Board of Directors and the AACT Board of Trustees.
