Pre-op Information for Patients

Medical assessment

On those occasions when the person to undergo surgery has general health concerns (with the heart or lungs for instance) it is wise to arrange for review by an anaesthetist or a physician at the hospital where the surgery will take place, but well ahead of the surgery date. This provides for specialised care in the immediate post-operative period, helping reduce the risk of complications.


Some medications have a major impact on surgery and the early post-operative period. Amongst the most important are medications that reduce clotting (“thin the blood”) and these may need to be stopped well before surgery because of possible bleeding problems. This group includes: warfarin; clopidogrel (Plavix, Iscover); ticlopidine (Ticlid, Ticlopidine Hexal, Tilodene); the newer anticoagulants (Pradaxa, Xarelto and Eliquis); all aspirin containing medications and most of the anti-inflammatory agents (but not Celebrex or Mobic). However, do not stop taking any medicines before discussing them with your surgeon.


Always tell your surgeon about any allergies to drugs so as to avoid potentially serious problems.

Admission to hospital

Once a plan for surgery has been decided upon, bookings will be made with the appropriate hospital. In most cases, admission to hospital is on the morning of the day of surgery. Nursing staff will supervise preparations for surgery on the ward and the anaesthetist will make a visit shortly before the time of surgery.
