Preparing for Surgery and Anaesthesia

Do I need Pre-Operative Anaesthesia Evaluation?

If you are scheduled for a surgery or procedure, you may need to undergo a pre-operative anaesthesia evaluation to assess your medical condition and help you to be medically prepared for surgery. The Pre-operative Evaluation Clinic (PEC) is located at SKH Medical Centre on Level 3 (see SKH Map)

If you are unwell before your appointment, please contact us soonest at +65 6930 6001 to reschedule, or your surgery date may be affected.

What to Expect During the Evaluation?

Our medical staff from the Department of Anaesthesiology will:

  • Evaluate your health status and risks for anaesthesia and surgery
  • Review all your medical records
  • Conduct history taking, physical examination and investigations (blood tests, electrocardiogram or chest x-ray)
  • Discuss various anaesthesia risks and options with you

A referral to other medical specialists may be needed depending on your assessment and investigations.

Please inform us if you or any family member has had problems with anaesthesia and/or surgery in the past. If you have seen a doctor at another institution, please bring along all medical reports, X-ray films, investigation results, and medications.

Do also inform us of all medications that you are consuming, especially blood-thinning medications (e.g. Aspirin, Chlopidogrel, Warfarin, Rivaroxaban, etc.), and any supplements including herbal and traditional medicines (e.g. cordyceps, gingko biloba, lingzhi, etc.) as these may potentially interact with drugs administered during surgery.

You will also be given several pre-operative instructions (e.g. medications to stop / continue), referral to other specialists (if relevant) and fasting timings.
