I'm truly not trying to scare you here but I tell everyone I know whose child is about to have a tonsillectomy and adnoidectomy - my daughter had this done last August. Please demand bloodwork be done prior to surgery! They did not run any bloodwork prior to hers and about halfway through the surgery the doctor came out to ask if we had any bleeding disorders in our family. Apparently they couldn't stop the oozing. We don't that I know of.
So after the surgery and while in recovery they took blood and ran numerous tests one of them being the PT/PTT test and also did the bleeding time test. While the bleeding time test came out ok the PT/PTT was not within normal (sorry I don't remember exactly how that test works). Anyhow, they kept her overnight and then sent her home the next day.
About 8 days later (she was still feeling somewhat lousy but wanted to get out of the house) we were at a Home Interiors party. She started coughing up blood - a lot of it it seemed. I called the doctor and he told me what to do. It seemed to stop and she didn't have any problems the rest of the day.
She woke me up about 2 AM and told me she was bleeding again...she was so pale. I took her downstairs and gave her the ice water then she fainted. When she came to I sat her down and she told me she felt sick. She then vomited and filled an 8 oz cup to the top with blood (they told me to meaure it). Then she fainted again. I called the doctor at home (per his instruction, no matter the time) and he said she would have to be brought in for surgery to control the bleeding. We live 25 miles from the hospital.
She spent another 4 days in the hospital after that. Her hemoglobins(?) were so low they were talking about transfusing her. They took several more tests and sent them to Mayo. Here ANA test came back positive but the pediatrician told me not to worry so much about that unless she tested positive again...I think it was a low titer speckled pattern? Nothing ever showed up in her bloodwork to point to any bleeding disorders, etc though. The next ANA came back negative.
When I asked in recovery the first time what the chances were of her bleeding to start again...they said with the doctor we had they couldn't remember ever having a patient come back with bleeding...but it can happen.
So...again, please ask that the routine blood work - PT/PTT be done prior to this and let them know ahead of time if your child or family has any bleeding problems or bruises easily. If you have any problems with bleeding after the surgery, go straight to the ER. I can't even imagine what would have happened had my daughter not woke up that night to tell me she was bleeding again.
Now, like I said before, I'm not telling you this to scare you, no flames please. Many people told me that their child was fine within a week or two and it is such a common procedure that there is nothing to be worried about. Obviously from my lack of knowledge about the blood tests, etc., I am not a medical expert. But, that being said, every surgery has it's risks. Please talk to your doctor about the bloodwork. Some hospitals, it is policy to do it, in others its not. Good luck and I hope your child breezes through with no complications.
