Information for patients undergoing an Ultrasound guided percutaneous drainage/aspiration procedure

Introduction

This leaflet has been designed to answer some of the common questions you may have regarding your percutaneous drainage/aspiration. This is the starting point for discussion about your treatment with the doctors looking after you, who wish to make sure you have received enough information about the procedure before signing the consent form.

Main text

A percutaneous drainage is a way of removing fluid, using a small tube (drain) through a tiny skin incision. This is usually performed to relieve the symptoms of the build-up of fluid such as ascites or infected collections. Some of this fluid may be sent off to be examined by a pathologist to gain further information about the nature of the fluid. The procedure is called “percutaneous” as it is done through the skin. The radiologist undertaking the procedure will use a US scanner to guide the tube into the correct place.

How long will I be in the department?

The procedure itself will take approximately 30 minutes. However, you will have a period of bed rest of up to 6 hours afterwards. This will be confirmed when your appointment is booked

What to do when you arrive

• Report to the Radiology Day Unit if you are attending as an Outpatient.
• If you are attending as an Inpatient, you will be allocated an appointment and the imaging porter will collect you in your bed to transfer to the US Department.

Staff you are likely to meet

• Radiologist
• Sonographer
• Radiology Nurse
• Clinical Support Worker
• Administrative Staff

Preparation for procedure/examination

Please contact the US Department Reception on 01223 216455 if you:

• Have additional requirements that may require a longer appointment,
• Require a specific appointment time due to taking time sensitive medication (e.g. insulin, medicines for Parkinson’s disease),
• Are claustrophobic,
• Are pregnant,
• Require hospital transport,
• Are unable to lie flat,
• Have mobility issues,
• If you are taking any blood thinning medications, like warfarin, Aspirin, Rivaroxaban, Dabigatran, Apixaban, Edoxaban, Clopidogrel or Ticagrelor you should inform your doctor before the procedure,
• have any allergies you must inform your doctor,
• Weigh 150 kg or more.

Benefits of the procedure

Other tests you have had have shown a collection of fluid. It may not be possible to determine what the fluid is from the previous test. If there is a lot of fluid it may be causing you discomfort which can be relieved by draining it. The fluid collection may be also be a cause of infection, which can be treated by draining it.

Risks

A percutaneous drainage is a very safe procedure, but as with any medical procedure there are some risks and complications that can arise.

The radiologist undertaking your drainage will explain the procedure and potential complications before you sign a consent form.

What will happen on the day of my procedure/examination?

You may have some blood tests prior to the procedure to check you do not have an increased risk of bleeding.

You will then be asked to lie on the ultrasound examination couch in the position that the Radiologist has decided is most suitable. Your skin will be cleaned with antiseptic and you may have some of your body covered with a sterile sheet. The Radiologist will use the US Scanner to decide on the most suitable point for inserting the needle and drain tubing.

Your skin will be then anaesthetised and the drain tubing inserted into the area of the fluid to be collected.

Most drainage procedures do not hurt. The local anaesthetic used to anesthetise the skin may sting to start with, but this will soon pass as the skin and deeper tissues become numb. You may also be aware of a pressure sensation as the needle and drain tubing passes into the deeper tissues but this is usually well tolerated.

The procedure may take approximately 30 minutes, although you will be in the department for a longer period to ensure there have been no complications.

The drainage tubing will be connected to a small bag where the fluid will collect.

This can be fastened to clothing or bed if required.

Accessibility requirements

If you require support for your appointment, e.g. if you find it hard to hear, see or be understood by others, please let the receptionist or healthcare professional know on arrival, email the accessibility team or telephone: 01223 256998.

Medication

Bring all of your medicines (including inhalers, injections, creams, eye drops or patches) and a current repeat prescription from your GP

Can I bring someone with me?

Those accompanying you will be required to stay out of the examination room during the procedure and remain in the waiting area.

Childcare whilst in department

Staff are unable to look after or supervise children whilst your procedure/examination is taking place. Please make alternative arrangements for the care of your children whilst you attend for your procedure/examination. If you attend an appointment with children with no one to look after them whilst you have your examination/procedure, then your appointment will unfortunately have to be cancelled and rescheduled.

Personal belongings

These would preferably be left on the ward or in the Radiology Day Unit in the designated storage area but can be brought down to the department if necessary – they will either be left on your bed (if kept in the room) or placed on the side.

What happens after my procedure/examination?

You will be asked to stay in bed for a few hours until you have recovered. A nurse will carry out routine observations, such as taking your pulse and blood pressure, to make sure there are no problems. If you have any pain following the procedure, we may give you some pain-relief medication.

Possible side effects and additional aftercare

If you feel unwell after your procedure, you should seek medical advice from your GP/hospital doctor or through the emergency department and inform them that you have had a drainage procedure.

You will be given an information sheet before you are discharged.

How, when and by whom will my results be communicated?

Your referring team or clinician will be responsible for communicating reports back to you.

Test result are made available via MyChart but there is 3 week delay from when an examination has been reported to when it is available on MyChart, in order to allow time for your clinical team to be able to see and action the results prior to them being released to the individual patient.

Are there any alternative tests?

If you are unable to have the drainage procedure under US guidance it may be performed under computed tomography
