• Consider consultation with ID and pharmacy in cases of multiple allergies, complex infection history, hepatic or renal dysfunction, and with ongoing pre-operative antibiotic therapy.

Pre- and intra-operative antibiotics For patients NOT currently on antibiotics: 

• Pre-operative dose should be completed within 60 minutes prior to the incision. 

• Patients who screen positive for MRSA should be given a singly pre-operative dose of vancomycin in addition to routine prophylaxis • Re-dose prophylactic antibiotic according to times in the table or if the patient has experienced excessive blood loss.

For patients currently ON antibiotics: 

• If treatment antibiotics appropriate for perioperative antimicrobial prophylaxis (AMP), continue schedule/follow intraoperative redosing table for timing of next dose. 

• If treatment is not appropriate for perioperative AMP, consider routine pre-op prophylaxis in addition to concurrent therapy. 

• Patients who screen positive for MRSA should be given a singly pre-operative dose of vancomycin in addition to routine prophylaxis

Post-operative continuation 

• For routine prophylaxis, antibiotics should not be continued after the incision is closed. 

• Redosing in the OR prior to closure should be considered if closure is anticipated within 30 minutes of the usual redosing time. 

• The first post-operative dose is timed off of last dose given prior to incision closure. 

• Operative guidance table does not apply to post-op dosing or intervals.
