[Analysis and diagnostic exploration of a dimethylacetamide poisoning incident in a small and micro enterprise].

The incident was a group poisoning incident caused by exposure to dimethylacetamide, resulting in different degrees of toxic liver disease in 6 workers.

The characteristics of percutaneous absorption of dimethylacetamide need to be paid great attention to, which can be used for reference to prevent similar incidents in the future.
