Our staff will go through an IR screening checklist with you one more time before starting.
Mild - Nausea, vomiting, abdominal discomfort, itching, rash, headache
Moderate - Fast/slow heart rate, high/low blood pressure, difficulty breathing
Severe - Convulsion, profound hypotension, arrhythmias, severe laryngeal oedema, cardiopulmonary arrest, death
You will be required to change into a hospital gown before the start of the procedure.
An intravascular cannula (a thin tube intended for collection of sample/delivery of fluid) may be inserted by our staff for contrast administration before the start of the procedure
Contrast medium administration:
Patients with prior contrast allergy/ poor renal function will be administered with an alternative special contrast. Adverse contrast reaction is rare but can happen.
There are several
categories of reaction severity:
During IR procedure:
Patient’s extremity/trunk will be cleaned and draped with sterile linen, small needle followed by fine wire/catheter will be introduced to target organ under radiological image guidance. Medication/implant will then be administered/deployed through the wire/catheter.
Medication/Injection may be given to make patient more comfortable during procedures.
After IR procedure:
For patients who have undergone the examination with contrast media, you will be monitored for any signs or symptoms of an allergic reaction after your scan. If you develop any symptoms like shortness of breath, body redness, itchiness or swelling, please inform any medical staff. If you develop any symptoms at home, head down to the nearest Emergency Department and inform them that you have went for a CT scan with contrast media earlier in the day.
The IV cannula used for intravenous injection of contrast media will be removed after the scan. You are advised to drink plenty of fluids to facilitate the excretion of contrast media.
