Dear Sir,

Snakebite is an important problem that is more frequent in the tropical world than in the Western world. The diagnosis of the problem is usually based on the clinical history. However, the use of a new diagnostic tool is interesting. The use of “sonography of snakebite” in cases of snakebite is very interesting. [1] Vohra et al. reported that “ultrasound imaging may allow for a more complete understanding of the local effects of snakebite” and observed “normal deeper muscle integrity in cases with diffuse leg edema.” [1] In fact, the observation of ultrasonosphy might not be specific to snake envenomation. It might be the classical sign of pressure effect due to local swelling. [2] The finding in some snakes, such as the cobra, which do not cause much swelling might be different from the report by Vohra et al[1] The role of ultrasonography seems to be limited in the diagnosis of snakebite but it might have some usefulness in monitoring the peripheral blood flow during the edema stage. [3] Finally, since snakebite can be fatal, the first thing is to save the life of the patient. The use of an unnecessary diagnostic tool should be less considered.
