Standard Operating Procedures and Notes for the Shoulder Team
Joint Replacement Prophylaxis Standard Operating Procedure (SOP)
All patients who receive and arthroplasty from the Shoulder and Elbow team are advised to take antibiotics prior to any procedure that may cause bacteremia. These procedures include dental work, sigmoidoscopy, proctoscopy, cystoscopy, or pretty much any procedure with the respiratory, digestive or urinary tract.
Patients should not have any procedures that may cause bacteremia for 2 weeks prior and 3 months post any arthroplasty surgery.
Dental Procedures
Members of the Arthritis Team (Shoulder, Elbow, Hip and Knees) should feel free to prescribe prophylactic antibiotics for joint replacement patients prior to a dental procedure. For dental procedures we follow the ADA and AAOS recommendations for antibiotics but extend use of them for life (as opposed to two years following arthroplasty and for high risk patients).
Respiratory, Digestive and Urinary Tract procedures
Since some of the choices for antibiotic include vancomycin and/or gentamicin, we reserve prescribing of these antibiotics to the surgeon doing the procedure - so that they can work up and follow the patient. If there are questions as what antibiotic course to take, we can give information about the AHA's recommendations for endocarditis prophylaxis and the AAOS' recommendations listed/linked below. It is also important to note that we consider all of our patients at high risk and recommend treatment for life, compared to the common practice of only provide prophylactic treatment for two years following arthroplasty surgery.

Prophylactic Regimens for Dental, Oral, Respiratory Tract, or Esophageal Procedures. (Follow-up dose no longer recommended.) Total children’s dose should not exceed adult dose.
I. Standard general prophylaxis for patients at risk:
Amoxicillin: Adults, 2.0 g (children, 50 mg/kg) given orally one hour before procedure.
II. Unable to take oral medications:
Ampicillin: Adults, 2.0 g (children 50 mg/kg) given IM or IV within 30 minutes before procedure.
III. Amoxicillin/ampicillin/penicillin allergic patients:
Clindamycin: Adults, 600 mg (children 20 mg/kg) given orally one hour before procedure. -OR-
Cephalexin* or Cefadroxil*: Adults, 2.0 g (children 50 mg/kg) orally one hour before procedure. -OR-
Azithromycin or Clarithromycin: Adults, 500 mg (children 15 mg/kg) orally one hour before procedure.
IV. Amoxicillin/ampicillin/penicillin allergic patients unable to take oral medications:
Clindamycin: Adults, 600 mg (children 20 mg/kg) IV within 30 minutes before procedure. -OR-
Cefazolin*: Adults, 1.0 g (children 25 mg/kg) IM or IV within 30 minutes before procedure.
*Cephalosporins should not be used in patients with immediate-type hypersensitivity reaction to penicillins.
Prophylactic Regimens for Genitourinary/Gastrointestinal Procedures: (Joint Replacement Patients should be considered High Risk for our purposes)
I. High-risk patients:
Ampicillin plus gentamicin: Ampicillin (adults, 2.0 g; children 50 mg/kg) plus gentamicin 1.5 mg/kg (for both adults and children, not to exceed 120 mg) IM or IV within 30 minutes before starting procedure. 6 hours later, ampicillin (adults, 1.0 g; children, 25 mg/kg) IM or IV, or amoxicillin (adults, 1.0 g; children, 25 mg/kg) orally.
II. High-risk patients allergic to ampicillin/amoxicillin:
Vancomycin plus gentamicin: Vancomycin (adults, 1.0 g; children, 20 mg/kg) IV over 1–2 hours plus gentamicin 1.5 mg/kg (for both adults and children, not to exceed 120 mg) IM or IV. Complete injection/infusion within 30 minutes before starting procedure.
III. Moderate-risk patients:
Amoxicillin: Adults, 2.0 g (children 50 mg/kg) orally one hour before procedure -OR-
Ampicillin: Adults, 2.0 g (children 50 mg/kg) IM or IV within 30 minutes before starting procedure.
IV. Moderate-risk patients allergic to ampicillin/amoxicillin:
Vancomycin: Adults, 1.0 g (children 20 mg/kg) IV over 1–2 hours. Complete infusion within 30 minutes of starting the procedure.

AAOS Antibiotic Prophylaxis for Urological Patients with Total Joint Replacements 2002
Risk Stratification of Bacteremic Urologic Procedures
- Any stone manipulation (includes shock wave lithotripsy)
- Any procedure with transmural incision into urinary tract (does not include simple ligation with excision or percutaneous drainage procedure)
- Any endoscopic procedures of upper tract (ureter and kidney)
- Any procedure that includes bowel segments
- Transrectal prostate biopsy
- Any procedure with entry into the urinary tract (except for transurethral catheterization) in individuals with higher risk of bacterial colonization:
- Indwelling catheter or intermittent catheterization
- Indwelling ureteral stent
- Urinary retention
- History of recent / recurrent urinary tract infection or prostatitis
- Urinary diversion
Lower Risk**
- Endoscopic procedures into urethra and bladder without stone manipulation or incision (includes fulguration and mucosal biopsy, if no incision)
- Open surgical or laparoscopic procedures without stone manipulation or incision into the urinary tract
- Catheterization for drainage or diagnostic instrumentation, including both transurethral and percutaneous access
* Prophylaxis for higher risk patients should be considered for patients with total joint replacement that meet the criteria in Table 1. No other patients should be considered for antibiotic prophylaxis prior to urologic procedures on the basis of the orthopaedic implant alone, although antibiotics still may be indicated for prophylaxis against urinary tract or other infections.
** Prophylaxis for lower risk patients not indicated on the basis of the orthopaedic implant alone, although antibiotics still may be indicated for prophylaxis against urinary tract or other infections.
Suggested Antibiotic Prophylaxis Regimens
A prophylactic antibiotic is chosen on the basis of its activity against endogenous flora likely to be encountered, its toxicity, and its cost. In order to prevent bacteriuria, an appropriate dose of a prophylactic antibiotic should be given preoperatively so that effective tissue concentration is present at the time of instrumentation or incision.
- Recommended agents include
- A single systemic level dose of a quinolone (e.g., ciprofloxacin, 500 mg; levofloxacin, 500 mg; ofloxacin, 400 mg) orally one to two hours preoperatively.
- Ampicillin 2 gm IV (or Vancomycin 1 gm IV over 1 to 2 hours, in patients allergic to ampicillin) plus Gentamicin 1.5 mg/kg IV 30 to 60 minutes preoperatively.9
- For some procedures, additional or alternative agents may be considered for prophylaxis against specific organisms.
