Tonsillectomy ABX protocol?

[SAS]

Hello,

 

I live in Nova Scotia Canada & my 11-year-old son is scheduled for a tonsillectomy in September and I was wondering if anyone knew of a physician recommended ABX treatment protocol for pre & post surgery? My son has been dx with PANS 5 years ago and we are hoping that the surgery can help reduce the frequency of flares. The ENT plans on giving him IV ABX during surgery along with a 2 week supply of ABX to take after the surgery. I remember reading something about a specific ABX protocol to follow before and after surgery but can't seem to track down that information now. My son takes prophylactic ABX regularly but I was wondering if he should be bumped up to a treatment dose 10 days before the surgery as well. Any information you can provide would be helpful. Thanks.
