Bee swarmings in children

Africanized honeybees (Apis mellifera scutellata) are now found in the southern and southwestern United States. Swarmings can result in hundreds to thousands of stings delivering a venom load capable of producing multisystem organ failure and death. The literature on mass envenomations is scarce, being limited to case reports and case series. There are no prospective studies on mass envenomations in children.

Methods

All patients were admitted to our toxicology service, and all stingers were counted. Laboratory data and clinical assessments were obtained at baseline, 8, and 16 hours after presentation.

Results

Nineteen patients with a median age of 3.6 years and a median of 2.64 stings per kilogram (range, 1-4.5) were enrolled. Fifteen children had vomiting. Only a mild increase in creatine kinase was seen. None developed coagulopathy or renal insufficiency.

Conclusion

Envenomations of up to 4.5 stings per kilogram resulted in only mild systemic illness. Vomiting does not portend involvement of other organ systems.
