Pre-Op Information

Pre-surgery information for all patients

Please advise our staff if you are taking anti-inflammatory or blood-thinning medications as you may be required to cease some medications 10 days prior to surgery.

Blood thinner medications

If you are currently taking these medications please contact us for instructions as to when these should be stopped prior to surgery. Bleeding during surgery is a significant complication and most blood thinners should be avoided 7+ days out from expected surgery.

Examples are: Plavix, Iscover, Astrix, Cardoprin, Xarelto, Fish Oil, Cartia & Warfarin.

For Warfarin patients this may require earlier admission to hospital.

Anti-inflammatory drugs

These should be ceased 7 days prior to expected surgery.

Examples are: Voltaren, Naprosyn, Aspirin, Mobic and Celebrex, Nurofen, Glucosamine, high-dose natural supplements e.g. Tumeric.

Diabetic patients

Please confirm with us if this affects you. Your planned surgery admission will be modified to cater for your condition.


Please be careful and avoid skin injuries/abrasions/minor infections to planned surgical limb. Please follow the fasting instructions given to you and remember to bring your X-rays to hospital if you have actual films. If you are uncertain we are always happy to answer your questions.

Extra pre-surgery dental information for joint replacement patients only

Our practice recommends that you visit your dentist and undertake any necessary dental work before undergoing planned Joint Replacement surgery. Dr Nielsen advises all patients who have had joint replacement surgery to take antibiotic prophylaxis for any procedure (surgical or dental) that has any risk of infection or bacteremia.

Extra post-surgery dental information for joint replacement patients only

After Joint Replacement surgery you must first advise your Doctor/ Dentist that you have had joint replacement surgery and to follow the same protocol as would be prescribed for patients who have had heart valve surgery.

The following protocol is appropriate if the treating doctor / dentist is unsure of the usual prophylaxis:

  • Amoxil 2 g one hour preoperatively – 500 mgs six hours later.
  • If allergic to Amoxil or Penicillin, Clindamycin should be used – 600 mg 1 hour pre-operatively then 300 mg six hours later.

Please provide this information to your dentist and keep this in your records.
