Abstract

SMIT, A et al. Point-of-care ultrasound assessment of a swollen limb following snakebite envenomation - an adjunct to avoid fasciotomy. S. Afr. j. surg. [online]. 2023, vol.61, n.1, pp.71-73. ISSN 2078-5151.  http://dx.doi.org/10.36303/SAJS.3907.

Acute limb compartment syndrome can occur with cytotoxic snake envenomation. Ultrasound (US) assessment of the affected limb has been suggested as an adjunct to the administration of snakebite polyvalent antivenom to ameliorate the systemic and local effects. US may also aid in the diagnosis of compartment syndrome and the need for fasciotomy to prevent limb loss. This report presents an adult male who had severe soft tissue swelling from a puff adder bite to the wrist and highlights the use of US in assessing and monitoring the degree of swelling in subcutaneous and fascial compartments of the arm. This US monitoring in conjunction with frequent physical examination avoided the need for a fasciotomy and its attendant morbidity, resulting in complete resolution of the swelling and full recovery of limb function.

Keywords : snakebite; envenomation; pseudo-compartment syndrome; fasciotomy; point-of-care ultrasound; POCUS; cytotoxic venom; painful progressive swelling.
