The Pellas hospital in Managua is considered one of the most modern in the world. My brother, who used to run the ER in Laguna Beach, is jealous of the equipment they have. Most of the doctors studied in the US. Remember, 50 years ago there was a revolution going on. Anyone who could, sent their children to the US to keep them safe. The revolution ended almost 35 years ago. Those children, and their children, are slowly returning. They are well educated, know US business methods and are relatively wealthy. They demand, and receive, good medical care. For something like brain cancer, they transfer the patient to Anderson in Houston, two hours away by air.
I've kept my membership to DAN (Divers' Assistance Network) for years even though I haven't gotten my feet wet since 1990. One of the features of membership is air evacuation for illness or accidents. It's good even if the problem has nothing to do with diving. I think if you travel a lot it's worth $45/year. (I think that's the basic membership fee.)
I can't send private messages on this board, but you can. If you'd like more information, PM a contact email and we can continue this offline.
