Anaesthetic Awareness Claims

We've got your anaesthetic awareness claim covered

Anaesthetic awareness means that a patient is conscious or semiconscious during a surgical procedure. This often occurs in procedures where an effort has been made by clinicians to use the minimum amount of anaesthetic and this has been insufficient to ensure complete anaesthesia during the procedure.

As well as the initial pain and fright from the experience, patients often experience long-term psychological effects as a result.

If you or someone you care about has suffered anaesthetic awareness because of poor medical treatment, we want to hear from you.

Here, we outline what goes into making your anaesthetic compensation claim, from:

  • Your initial suffering and what this means
  • How it feels during anaesthetic awareness
  • How and why this has happened
  • How we can process your claim

All our legal professionals are experts in medical negligence and will handle your call with care and consideration.

For your claim to succeed, we will need to prove two things “on a balance of probabilities “ (this means “more likely than not”) – first, that the care you received was below the standard to be expected of a reasonably competent medical professional, and second, that this substandard care has caused you to suffer an injury which you would otherwise not have suffered.

What it means to suffer anaesthetic awareness

A comprehensive national survey of anaesthetists found that reports made to them of accidental awareness during general anaesthesia (AAGA) were rare, at about one case per 15,000 general anaesthetics. However, while the numbers are small in absolute terms, such cases often settle in the claimant’s favour.

If you are considering making an anaesthetic injury claim, you may be experiencing one (or more) of many debilitating after-effects, which include (but are not necessarily limited to):

  • Post-traumatic stress disorder
  • Other ongoing psychiatric conditions
  • Flashbacks

Flashbacks as a result of anaesthetic awareness or anaesthetic negligence are vivid experiences whereby an event or time of trauma feels as if it is happening once again.

For some, flashbacks can feel as if somebody is replaying what happened to you in technicolour detail, as if watching a film. To others, there are signs of:

  • What happened being replayed before their eyes
  • Taste, sounds and smell can become extremely sensitive
  • Feelings of pain can arise, almost from nowhere, related to the incident
  • Memories or thoughts at the time of the incident can come back

How the patient feels during anaesthetic awareness

When anaesthesia awareness does happen, patients report varying levels of sensations and awareness.
Most patients will only experience a hazy and very brief awareness, frequently one incident during surgery – for example, the sensation of something being inserted into their mouth, or awareness of people moving and talking around them. Slightly more serious are those cases where the patient is conscious of their surroundings but experiences paralysis. Most episodes of awareness are short, lasting no more than five minutes, but no less distressing for that.

There are also rare examples where a patient experienced incredible physical pain. Worse, they were unable to communicate what was happening.

Most instances of anaesthetic awareness happen at the beginning or end of surgery – as the surgeon is putting you to sleep or you are waking up.

If you have felt anything at all under general anaesthetic, then those responsible for ensuring that you were unconscious may have breached their duty of care to you. Generally speaking, under the correct dosage of anaesthetic you should not feel a thing because of your unconscious state.

Common reasons for anaesthetic awareness

Incorrect dosage

The wrong dosage of medicine is a common reason for anaesthetic awareness.
If the dosage was too low and starts to wear off during surgery, you may start to regain your sensations of touch, sound, smell and even sight.

If this happens, the sensation is usually brief, but patients have been known to be able to recall conversations between those operating and hear the room’s machinery around them. If this happened to you, our team will take a detailed statement to use as evidence in making an anaesthetic injury claim.

Medical condition-related surgery

There are a number of risk factors which can increase the risk of anaesthetic awareness during surgery. These include:

Patient factors

  • Being aged 25-45
  • Being classed as obese
  • Being female

Types of Surgery

  • Obstetric (childbirth) surgeries
  • Thoracic (chest) surgeries
  • Cardiac (heart) surgeries

These types of surgery are higher risk because the use of anaesthesia itself is higher risk. For example, in childbirth cases, surgeons need to consider the effect of anaesthesia on both mother and child and may misjudge the correct dose.

Clinical Settings

  • Use of muscle relaxants
  • Emergency use of anaesthesia
  • Out of hours surgery
  • Interaction with other medication
  • Alcohol and drug use

For these reasons, it is vital that the operating clinicians take as full and detailed a medical history of their patients as they can before surgery so that they are in a position to make the best possible judgement about the treatment to give.

Inexperienced medical staff

Another factor is when the anaesthesia is performed by inexperienced or unsupervised trainees or medical professionals.

For a clinical negligence claim to be successful, it is necessary to show first of all that the care you received was below the standard which can be expected of a reasonably competent medical practitioner. This applies to trainees as much as it does to fully-qualified staff, because it is assumed that there will be proper supervision and training in place.

Experience and know-how is key, and those monitoring the anaesthetic should have the necessary level of training and experience. If that is not so, then there may have been negligence.

Equipment failure

Faulty equipment can be another reason for anaesthetic awareness. All necessary equipment should be checked at the start of every day to ensure that it is in working order, and there should be back-up equipment and drugs available at all times. Staff should be trained and equipped to deal with those situations where both main machinery and any back-ups are faulty.

Sarah's Story

"Now we have peace of mind"

My husband, Nick, went back and forth to the doctors for a long time and tried everything the doctor recommended. But his illness got worse, to the point that he was in agony.

In the end we got so desperate that we asked for a referral. The doctor was reluctant, so we had to consult a private hospital. That’s when we found out there was a tumour. It took years from the onset of his illness to finally start cancer treatment.

He used to be a man with a lot to live for, but in the end he was in so much pain that he withdrew from the family. He became angry that nobody had helped him sooner, and the legal team were able to give him the validation that he was desperately seeking. The NHS confirmed if they had done more, Nick would still be alive today.
