Vascular Research Team

Regular Off Off

Vascular Surgery Research Team

Our Surgery Research team is a dedicated group of nurses, administrators, and surgeons, conducting studies across specialities including Colorectal, Upper Gastrointestinal (UGI) and Vascular.

Our research is supported by the Department of Health with our research projects encompassing a wide breadth of both laboratory-based and clinical work, to improve patient health, wellbeing and care.

We work on a range of commercial and non-commercial, qualitative and quantitative projects and collaborate with colleagues locally, nationally and internationally in order to improve outcomes for patients suffering from various conditions. 

Our work benefits patients not only here in the NHS, but also increases care standards globally.

The team has a wealth of experience conducting research studies and trials, and improving training, guidelines, and patient outcomes.

Our staff work in close collaboration with a number of partners, primarily linked with the University of Bristol and University of the West of England (UWE) as well as a number of other NHS Trusts.

Team Members:

Samantha Loud

Lead Research Nurse

Sam currently works as the Lead Research Nurse for the Surgery Research team overseeing Colorectal, UGI and Vascular Research at Southmead Hospital, managing a team of 6 competent research practitioners. Having qualified in 2000 as a Children’s Nurse, she began her career working in the Paediatric Intensive Care Unit at Bristol Children’s Hospital where she worked for 7 years. She then moved and worked for 4 years on a busy Surgical and Trauma ward.  

After seeing an advert for the opportunity of a research nurse post at led jointly with NBT (North Bristol Trust) and UoB (University of Bristol) working with Children and their families researching into the risk of developing Type 1 diabetes she jumped at the chance for a new challenge. She spent 9 years in this post working her way up, initially as a junior nurse band 5 to a senior nurse band 7 role where she then led the team and managed the research project. This came to an end in 2020 when the study funding finished.

Sam was then offered the opportunity of a completely new role and challenge within NBT as the Senior Research Nurse for Surgery. This involved putting together smaller teams within different areas of Surgery research bringing them together as one team. This has been a success; the team has grown and consists of dedicated research nurses and administrators and is still growing! We have opened and reopened many studies across all the areas which are recruiting well.

Sam has lots of plans to extend this over time and build a bigger team to be able to cover more areas of surgery in the future.

Cardioversion

Regular Off Off

This page is for patients and their families when preparing for a cardioversion.

What is a cardioversion and how is it done?

Cardioversion is done in hospital under a short general anaesthetic (you will be asleep) to treat an abnormal heart rhythm. 

The doctor will place electrode ‘sticky pads’ on the front and back of your chest and send electrical energy through the chest to the heart. This energy is synchronised (works at the same time) with your own heartbeat and should return your heart to the normal regular rhythm. 

Cardioversion is usually done as a day case, so that you come to hospital and go home the same day. Occasionally it is necessary to stay overnight.

Why do I need to have a cardioversion?

You may have been having palpitations or an irregular heart beat for some time. Your doctor may have prescribed a course of tablets such as amiodarone, digoxin, bisoprolol, or diltiazem to control your heart rhythm. These are not always successful and if you are troubled by palpitations, breathlessness, chest discomfort, or reduced activity then cardioversion may help. By restoring your heart’s normal regular rhythm (sinus rhythm) your symptoms can improve.

Will it be successful?

The cardioversion is more likely to be successful if your heart has been in an abnormal rhythm for only a short while, like a few months. The effectiveness varies, but in 9 out of 10 people the cardioversion will restore the normal regular rhythm.

However, some of these people will go back to how it was in the next few days or weeks. In a few cases the procedure will not be successful at all.

For 5-6 people out of 10 who have cardioversion, their heart will likely still be in the normal regular sinus rhythm 12 months later.

The best results are seen in patients with normal heart structures seen on an echo scan. Patients with structural heart impairment, for example leaky valves or enlarged heart chambers, have a lower chance of long-term success.

Before you come into hospital

Your doctor will prescribe a blood thinning medication called oral anticoagulant, for example apixaban or dabigatran. These are taken twice a day for 4-6 weeks before the cardioversion and you will continue taking them afterwards. It is important that you don’t miss doses of the anticoagulant as this can increase the slight chance of having a stroke following the cardioversion.

You will be seen by a cardiology pre-op assessment nurse, before your procedure date. Usually, the procedure is done as a day case procedure (home on the same day).

The nurse will talk to you, take a blood sample, do an ECG recording, and check that that you can get to the hospital, and someone can take you home. You will not be able to drive yourself home.

Important information

  • You must not eat or drink for at least six hours before your admission to prepare for the general anaesthetic.
  • Take your regular medications as usual, early on the morning of your cardioversion with a small sip of water.
  • If you are taking digoxin, you should stop taking it 48 hours before you come to hospital.
  • If you are diabetic, the pre-assessment nurse will explain what you need to do before you come into hospital.

When you arrive at hospital

You will be seen by a nurse and a doctor who will talk about the procedure and answer any questions you have. You will then be asked to sign a consent form to show that you are happy to have the treatment.

The anaesthetist will talk to you about what will happen and ask you about your health and any allergies you may have.

You will be attached to a cardiac monitor to record your heart rate. Staff will take your blood pressure and record your breathing rate.

The anaesthetic will be given through a small needle in the back of your hand and as you drift off to sleep the electrical cardioversion will be done. The procedure takes about 5 minutes. You will then be taken to the recovery area.

What happens next?

You will sleep off the effects of the anaesthetic and wake up in your own time. When you wake up you will probably be lying on your side and wearing an oxygen mask. The nursing staff will monitor your blood pressure, heart rate, and breathing rate.

When you are fully awake you will be told how the procedure went and staff will be happy to answer any questions. Some people feel slightly sick after anaesthetic, but you will be given a drink and something to eat when you feel able to.

When you have recovered, you will have another ECG done to see if the procedure has been successful.

As long as you feel well enough, you will be able to be collected and go home 2-4 hours after your treatment.

Even if the treatment has been successful, the doctor may tell you to continue taking some or all of your tablets for a while longer.

An outpatient appointment will be arranged for you to see your hospital doctor who recommended the cardioversion and you can ask about your medicines then.

Please remember it takes a while to recover from a general anaesthetic.

For 24 hours after cardioversion:

  • You must not drive.
  • You must not operate any potentially dangerous devices as your reflexes may be reduced.
  • You must not make any important decisions or sign any legal documents.
  • Do not drink alcohol.
  • Do not boil a kettle or use anything that involves heat.
  • When rising up to sitting or standing, do it slowly as you may feel dizzy if you get up too quickly
  • We advise you to rest for the remainder of the day after your treatment and to take the next day off work.

What risks are there?

Cardioversion is a safe procedure which has been done in most hospitals in the UK for many years.

Complications are rare, but there are risks that you need to think about before you sign the consent form.

These risks are higher in patients who are very unwell or have certain medical conditions. You need to weigh up the risks of having the procedure or leaving the condition untreated, against the potential benefit of the procedure.

Below are approximate complication rates for patients having cardioversion. However, you need to remember that these numbers include all patients, regardless of how ill they were to start with.

  • Risk of an anaesthetic problem or death is one in every 100,000 patients.
  • Risk of having a stroke or another type of blood clot problem is approximately one in every 1000 patients.
  • There is a minor risk of slight burns to the chest from the paddles or adhesive pads used during the procedure.
  • Rarely, some patients may require a temporary pacing wire to be inserted if the heart beats too slowly.
  • Rarely the procedure causes a more serious, life threatening abnormal heartbeat. This is so uncommon that there are no available statistics.

Your CT virtual colonoscopy

Regular Off Off

Introduction

You have been advised by your doctor to have a Computerised Tomography investigation, more commonly called a CT scan. This leaflet explains what a CT is, the benefits and risks, and what the virtual colonoscopy CT involves. If you have any further questions please speak to the member of the team looking after you.

CT scans are done in the Imaging department - also known as Radiology or X-ray department. This is the department in the hospital that does radiological examinations such as X-rays, CT scans, and others.

Radiographers are highly trained operators that carry out CT scans with the help of radiology department assistants. They make sure the best possible images are taken while using the minimum dose of radiation. Radiologists are doctors specially trained to interpret the images when the scan is complete.

What is a CT virtual colonoscopy?

A CT scanner machine uses ionising radiation (X-rays), and a computer to produce very detailed cross-sectional images of any part of the body. The information is built up into a series of pictures for the radiologist to view.

CT virtual colonoscopy is different from other CT scans because carbon dioxide is used to inflate the colon (large bowel), via a thin flexible tube that is inserted into the back passage (anus). The CT scanner the puts together a detailed 3D model of the colon, which the radiologist uses to view the bowel in a way that simulates travelling through the bowel. This is why the procedure is called a virtual colonoscopy.

At the same time, 2D images of the colon, abdomen, and pelvis are taken without any additional radiation.

Are there alternatives to a CT virtual colonoscopy?

The alternative way of looking at the large bowel is endoscopy. Endoscopy involves using a tube with a camera on the end (colonoscope) which is passed into the back passage, an moved up and around the bowel. Although it doesn‘t use radiation, it is more invasive than a virtual colonoscopy and usually requires sedation. However, it does allow for a biopsy or removal of small polyps at the same time.

Do I need to prepare for this examination?

  • We will send you a special medicine before the scan. Please mix this with water and follow the instructions given to you on a separate leaflet. This medicine may cause diarrhoea, which is required to empty the bowel. It also coats the lining of the bowel so we can see it on the scan. 
  • You will also be given a separate leaflet with what foods you can and cannot eat. Please follow these instructions carefully.
  • Please drink plenty of water over the 2 days before the scan. 
  • If you are diabetic and have received an afternoon appointment, please let us know. Morning appointments are available to ensure you can follow the preparation safely.

What happens during the scan?

  • The Radiology department assistant will explain the process and ask you to change into a hospital gown. You will then be taken into the scan room where the radiographer will again explain and answer any questions.
  • A small cannula will be put into your arm so that a muscle relaxant can be injected. This drug is used to relax the involuntary muscles of your bowel to reduce discomfort and decrease bowel movement on the scan.
  • You will be asked to roll onto your side and a small flexible tube (around the width of a pencil and 2 inches in length) will be inserted into your back passage. A lubricant is used to ease this process.
  • Carbon dioxide gas will then be passed through the tube and into the large bowel for the duration of the examination to maintain inflation. You will be asked to move into different positions on the scanning table (on your front, back and sides) and several scans will be taken.
  • The radiographers will check the quality of the images and ensure they have all the information required from each position. Occasionally, more information may be required, and the scan will also include your chest. A contrast dye will be inserted into your cannula during the scan if this is required.
  • During the scan you will be asked to hold your breath and retain the gas as much as possible whilst the table moves slowly. You will move in and out several times. Occasionally, a contrast dye may be given through the cannula and the scan to provide more information.
  • The whole examination will take around 30 minutes and is very clean. A small balloon on the tube keeps the tube in place and any faeces (poo) left inside you will go down the tube. You will not be given sedation for this examination.
  • Once all the images are taken the tube will be gently removed. You will then be taken into a joining room where there is a toilet and your clothes to get dressed. The team will talk to you before you go to ensure you feel ok.

What happens after the scan?

You may eat and drink as normal. Please drink plenty of water as the bowel preparation medicine may dehydrate you. 

The carbon dioxide gas will naturally be absorbed by the body and the bloated feeling will subside quickly once you have passed wind and used the toilet. 

The radiologist will examine the images in detail and send the written results to the consultant or GP that referred you for the scan. You will get your results from that doctor.

What are the risks and benefits of having a CT virtual colonoscopy scan?

A CT scan involves the use of ionising radiation (X-rays); we are all exposed to natural background radiation every day from radioactivity in the air, food that we eat and even from space.

Exposure to ionising radiation from a CT scan carries a small risk, however, the main benefit of having the scan is to get an accurate diagnosis so that you can get the right treatment for you. A specialist will have agreed that the benefit, of the scan, outweighs the risk of the ionising radiation and we can assure you that all safeguarding to minimise ionising radiation exposure is taken.

If there is a possibility that you may be pregnant, then please contact the radiology department prior to the scan.

During the CT virtual colonoscopy, you may experience abdominal discomfort and bloating, this is normal but if it becomes too painful then please let the radiographer know. Once the scan is complete you could become faint when sitting up, however, the team follow several steps to limit.

There is a very small risk that inflating your bowel with air could cause injury to or perforation of the bowel, however, this occurs in fewer than 1 in 10,000 patients. This will, in most cases, heal itself, however, may require medical assistance or antibiotics.

If you have had the injection of muscle relaxant, you may experience a dry mouth and blurred vision. The latter is very rare, but if it does happen, it will wear off within 30 minutes but please do not drive until your vision is back to normal. Please let the radiographer know if you suffer from angina, any heart problems or glaucoma.

Some patients may require an injection of contrast medium, also described as X-ray dye, for their scan which increases the amount of information seen on the scan. There is a small chance of an allergic reaction to the injection of contrast medium, however, the Imaging team are trained to deal with any complication, and again the risk is very small. The Imaging team will make sure you are feeling alright and have recovered before letting you leave the department.
