Blood lead level (BLL) testBLL 70 ug/dL or greater: medical treatment is immediately provided
BLL 20 to 44 ug/dL: A BLL greater than 20 ug/dL is considered acute; clinical management, including treatment, environmental investigation, & lead-hazard control

Principles:Determine substance taken, assess LOC
Unless poison is corrosive, caustic (strong alkali such as LYE) or a hydrocarbon, vomiting is the most effective way to remove poison.

Vomiting will occur within 20 minutes after giving Ipecac
If vomiting did not occur within 20-30 minutes; another dose maybe given
![Page 183: GI Disorders Final](https://reader031.vdocuments.us/reader031/viewer/2022020115/5467c881b4af9f0c038b49ea/html5/thumbnails/183.jpg)
