Anesthesia is one of the most tightly protocol-driven areas of medicine and one of the most dangerous when something goes wrong.
If you or a loved one suffered brain damage, cardiac arrest, airway trauma, or awareness during surgery due to an anesthesia error, one of the most important early questions in your case is: who was actually responsible?
In Illinois, that answer often involves more than one party.

Common Anesthesia Errors
Anesthesia errors generally involve medication administration, patient monitoring, or airway management.
Dosage-Related Errors
Examples include:
- Giving too much anesthesia, which can cause respiratory or cardiac arrest
- Giving too little anesthesia, which may cause anesthesia awareness
- Failing to consider the patient’s weight, age, allergies, or medical history
- Failing to account for interactions with other medications
- Failing to properly monitor vital signs during the procedure
Intubation and Airway Errors
Intubation involves placing a breathing tube into the airway to help a patient breathe during surgery.
Potential errors include:
- Placing the tube in the esophagus instead of the trachea
- Failing to identify a difficult airway before surgery
- Injuring the teeth, throat, or vocal cords during intubation
- Failing to recognize a blocked, displaced, or failed airway
- Failing to take appropriate precautions to prevent aspiration
An anesthesia error can become life-threatening within minutes. Patients under general anesthesia cannot report problems themselves, making proper monitoring and timely intervention especially important.
Who Provides Anesthesia Care, And Why It Gets Complicated
Anesthesia care in Illinois hospitals is typically delivered through one of several staffing models, which is precisely what makes liability more complex than in a single-provider malpractice case:
- Anesthesiologists — physicians (MDs or DOs) who have completed medical school and an anesthesiology residency, and who may personally administer anesthesia or supervise a care team.
- Certified Registered Nurse Anesthetists (CRNAs) — advanced practice nurses with specialized anesthesia training who may administer anesthesia independently or under an anesthesiologist’s supervision, depending on the hospital’s staffing model and any supervision agreement in place.
- Anesthesiologist assistants — mid-level providers who work under the direct supervision of an anesthesiologist.
- The hospital or surgical center — which sets staffing protocols, supervision requirements, and is responsible for ensuring adequate equipment and monitoring is in place.
When a CRNA administers anesthesia under a supervising anesthesiologist’s protocol, an error can implicate either provider or both, depending on whether the mistake stemmed from the CRNA’s hands-on technique or from inadequate supervision, unclear delegation, or a flawed protocol set by the anesthesiologist.
Who May Be Liable for an Anesthesia Error?
Anesthesiologist Liability
An anesthesiologist may be responsible when they:
- Personally administered anesthesia or performed the intubation
- Failed to properly supervise another anesthesia provider
- Approved an inappropriate anesthesia plan
- Failed to respond to signs of a developing complication
CRNA Liability
A CRNA may be responsible when they:
- Made an anesthesia dosage error
- Failed to follow the applicable anesthesia plan or protocol
- Failed to recognize warning signs on patient monitors
- Improperly performed an intubation
Hospital Liability
A hospital may have liability when it:
- Failed to properly credential or verify an anesthesia provider’s qualifications
- Failed to meet applicable staffing or supervision requirements
- Provided inadequate monitoring equipment or procedures
- Had staffing or communication problems that contributed to the error
A hospital may also be responsible for the negligence of employees. In some circumstances, liability may extend to non-employee providers under an apparent agency theory.
Determining who is legally responsible requires an analysis of the provider relationships, hospital policies, medical records, and applicable Illinois law.
How Is Anesthesia Malpractice Proven in Illinois?
An Illinois medical malpractice claim generally requires evidence of four key elements:
- Duty of care: A healthcare provider owed the patient a duty to provide appropriate care.
- Breach of duty: The provider failed to meet the applicable standard of care.
- Causation: The provider’s conduct caused or contributed to the patient’s injury.
- Damages: The patient suffered measurable harm, such as medical expenses, disability, lost income, or other damages.
Illinois medical malpractice claims also generally require a qualified healthcare professional to provide a written report supporting the claim before filing suit.
Anesthesia cases may require review by specialists with relevant experience, such as an anesthesiologist or nurse anesthesia expert.
Illinois Statute of Limitations for Anesthesia Malpractice Claims
- Adults: Generally 2 years from when the injury was discovered or reasonably should have been discovered, but no more than 4 years from the date of the negligent act (735 ILCS 5/13-212).
- Minors: Generally 8 years from the date of injury, but no later than the child’s 22nd birthday.
- Wrongful death claims: Generally must be filed within 2 years of the date of death.
Because anesthesia records, including minute-by-minute vital sign logs and drug administration timestamps are central to these cases, early legal review is critical to ensure this documentation is preserved before it can be lost or overwritten.
What Compensation May Be Available?
Depending on the circumstances, compensation in an Illinois anesthesia malpractice case may include:
- Past and future medical expenses
- Costs of long-term or lifetime care
- Lost wages and reduced future earning capacity
- Pain and suffering
- Loss of normal life
- Psychological harm related to anesthesia awareness
- Funeral and burial expenses in a wrongful death case
The damages available depend on the facts of the case and applicable Illinois law.
Evidence in an Anesthesia Malpractice Case
Important evidence may include:
- Anesthesia records and medication administration records
- Vital sign and monitoring records
- Pre-operative anesthesia assessments
- Airway evaluations
- Intubation and procedure notes
- Anesthesia plans and protocols
- Records identifying the supervising anesthesiologist and CRNA
- Hospital staffing and credentialing records
- Medical records documenting the resulting injury
- Review by qualified medical experts
These records can help establish what happened, which providers were involved, and whether the applicable standard of care was followed.

Frequently Asked Questions
Can I sue the hospital if a CRNA made an anesthesia error?
Possibly. A hospital may be liable for a CRNA’s negligence in certain circumstances, such as when the CRNA is a hospital employee. A hospital may also have separate liability related to staffing, supervision, credentialing, or hospital procedures.
Spiros Law can review the anesthesia records and circumstances to identify the providers involved and determine whether a potential malpractice claim may exist.
What is anesthesia awareness?
Anesthesia awareness occurs when a patient becomes partially or fully conscious during surgery despite receiving anesthesia. It can cause psychological distress and other lasting effects.
Anesthesia awareness does not automatically mean medical malpractice occurred. An expert review of the anesthesia records and circumstances is generally needed to determine whether the care met the applicable standard.
Spiros Law can review what happened during the procedure and the available medical records to determine whether the anesthesia care may have fallen below the required standard.
How can I find out who provided my anesthesia?
Anesthesia records and procedure notes can identify the healthcare providers involved in your care. These records may show who administered the anesthesia and whether an anesthesiologist supervised the procedure.
An attorney can request and review these records during a case evaluation.
Spiros Law can help identify the anesthesia providers involved and review the records for potential errors, omissions, or other issues.
Can an esophageal intubation cause brain damage?
Yes. Esophageal intubation occurs when a breathing tube enters the esophagus instead of the trachea. This can prevent adequate oxygen from reaching the lungs. If the error is not recognized and corrected quickly, oxygen deprivation can cause permanent brain damage or death.
Spiros Law can review the intubation records, treatment timeline, and resulting injuries to determine whether the circumstances may support an anesthesia malpractice claim.
Do I need money upfront to hire an anesthesia malpractice lawyer?
No. Spiros Law handles qualifying anesthesia malpractice cases on a contingency-fee basis. There are no upfront attorney fees, and you pay no attorney fee unless compensation is recovered for you or your family.
If you believe an anesthesia error caused an injury, Spiros Law can review your situation and explain whether you may have a potential malpractice claim without requiring an upfront attorney fee.
