I am glad to hear that your grandson is doing well. Do you know who the anesthia was provided by: was it a cerified register nurse anesthesiologist(CRNA), or an medical doctor that specialized in Anesthesiology. It is quite common now a days for crna's to adminster the anesthesiology instead of an actual M.D. This is quite alarming in my opinion considering the difference in education levels between CRNA and the Anesthesiology Docs. Anesthiology docs on average are educated for 12 years as opposed to the 6 years that the CRNA's recieve. Next time anyone in your family undergoes surgery you should reqeust that an Anesthiology Doctor adminster the anesthesia, they are much more knowledgable and more capable of handling emergencys that might arise during surgery.
