Healthcare Work In Los

When I return next month, for what I think will be a permanent stay, I hadn't planned on working. The more I think about it though, I may get bored. I was a critical care/emergency/ flight nurse in the US for 15 years. Specialized in pediatrics. Does anybody know if I can do this kind of work in Thailand. I will be in Phuket and understand that they have something like an international health coordinator position at the international hospitals. I'm not sure what that is. I certainly don't want to get back into full time, high stress employment, but maybe a part time thing. Anybody have any input??? Volunteer work is fine.
