The anesthesiologists, Sarah, Steve, Helen, and Denise (pictured) often experience difficulties that they might not have to face back home in the USA. Denise explains: My major challenge is in making the kids comfortable so the surgeons can perform. We have to keep them medically stable, which is sometimes difficult with their frequent respiratory infections. With the intense heat, and having to keep them NPO in a non air-conditioned waiting area, they are sometimes dehydrated before they come to us. It can be a real challenge getting IVs into those tiny veins.
