My mother is in a hospital due to a staff infaction. While she is in there a nurse overdosed her on insulin. Gave her 50 units instead of 5. Notified mom and the doctor immidiatley and counter measures where started. Moms blood sugar levels went over 500 then began to drop over the course of 3 hours to around 200. The doctor said it could have killed her. He also said he didnt think there was any permanent damage. My question is what kind of permanent damage could there even be and how do I keep check for it? They transfered her to a rehab already so I dont know what to keep an eye out for. She has heart problems, kidney failure, bloodpressure and other issues already.
