Medical error during anesthesia: liability and compensation

Local or general anesthesia is often an indispensable part of a surgery or medical procedure. Patients trust that the anesthesiologist carries out everything carefully. Still, something can go wrong with anesthesia, sometimes with serious consequences. In that case, there may be a medical error, for which the doctor or the hospital may be liable.

In this blog, we explain when an anesthesia error is legally actionable, what rights you have as a patient, and how to claim compensation.


What exactly does an anesthesiologist do?

The anesthesiologist is responsible for:

  • administering anesthesia (local or general);

  • monitoring your vital signs during the procedure;

  • providing pain management after the operation;

  • and checking risks beforehand, such as allergies or pre-existing conditions.

The smallest mistake can have major consequences. That is why strict medical protocols and safety standards apply to anesthesiologists.


When does a medical error occur in anesthesia?

Not every incident or complication during anesthesia is automatically a medical error. An error is legally culpable only if the anesthesiologist did not act as a reasonably competent and careful physician would under the same circumstances.

Examples of medical errors in anesthesia include:

  • Incorrect dosage of the anesthetic.

  • Incorrect intubation, resulting in oxygen deprivation.

  • Insufficient monitoring of vital signs during surgery.

  • Not responding promptly to complications or alarm signals.

  • Insufficient preparation or medical risk assessment.

  • Incorrect administration of medications (for example, mixing up syringes).

  • Failure to check for allergies or prior complications.

In all these situations there may be negligence — a breach of the duty of care that leads to liability.


What are the possible consequences of an anesthesia error?

The consequences can be severe, depending on the nature of the error. Common complications include:

  • oxygen deprivation (hypoxia) resulting in brain injury;

  • nerve damage due to incorrect positioning or needle technique;

  • cardiac arrest or respiratory problems;

  • consciousness during anesthesia (“awareness”);

  • allergic shock (anaphylaxis);

  • long-term cognitive complaints after anesthesia, such as concentration problems or memory loss.

When it is established that these complications are the result of culpable conduct, the patient can claim compensation.


The duty of care of the anesthesiologist and the hospital

The anesthesiologist must act in accordance with the professional standard. This means:

  • careful preparation, including risk analysis;

  • proper administration of anesthesia and monitoring;

  • and adequate post-operative care.

In addition, the hospital has an organizational duty: it must ensure safe equipment, well-trained staff, and clear protocols.
If this duty of care is breached, the hospital is usually liable — not the individual doctor.


How can you prove that a mistake was made?

In anesthesia-related incidents, evidence is often difficult because the patient is under anesthesia and has observed little themselves. Still, you can do the following:

  1. Request your medical record.
    It contains anesthesia reports, medication information, and observations.

  2. Have the record reviewed by a medical advisor.
    They compare the course of events with the applicable protocols and can determine whether there are deviations.

  3. Gather additional information.
    Think of witness statements from nurses or family members, correspondence, or complaint reports.

Compensation after a medical error during anesthesia

When liability has been established, you are entitled to compensation for both material and non-material damage.

Material damage includes among other things:

  • medical expenses (treatments, medication, rehabilitation);

  • loss of income due to incapacity for work;

  • travel expenses to hospitals or specialists;

  • assistance with housekeeping or personal care;

  • costs for home modifications or assistive devices.

Non-material damage (pain and suffering) compensates for the suffering, the pain and the loss of enjoyment of life.
The amount depends on the severity of the injury, the recovery, and the impact on your daily life.

What can you do after an error with sedation or anesthesia?

  1. Ask the doctor or hospital for an explanation.
    A conversation can often provide a lot of clarity.

  2. File a complaint.
    Every healthcare institution has a complaints procedure with a complaints officer.

  3. Consult a specialized personal injury lawyer.
    This professional can help you assess liability, request reports, and claim compensation.

When is an anesthesia complication considered a medical error?

An anesthesia complication is considered a medical error if the anesthesiologist failed to act as a reasonably competent professional would under similar circumstances, such as administering the wrong dosage or failing to monitor vital signs properly. Not all adverse events are automatically medical errors; negligence must be established.

You may be entitled to compensation for medical expenses, pain and suffering, loss of income, and long-term rehabilitation costs if the injury resulted from a culpable medical error. An attorney can help assess the extent of damages and assist with the claim process.

Hospitals must adhere to strict safety protocols, maintain well-trained staff, and use properly maintained equipment to prevent anesthesia errors. Ensuring thorough risk assessments and proper monitoring also helps minimize the risk of harm during procedures.
