Anesthesia makes modern surgery possible, but administering it requires careful planning, continuous monitoring, and a prompt response to changes in the patient’s condition. When an anesthesiologist, nurse anesthetist, hospital, or other healthcare provider makes a preventable error, the patient may suffer oxygen deprivation, permanent brain damage, or death.
Not every anesthesia complication is malpractice. Some adverse events can occur even when medical professionals follow accepted safety practices. However, when a healthcare provider fails to meet the appropriate standard of care and that failure causes a brain injury, the patient or the patient’s family may have grounds for a medical malpractice claim.
How Can an Anesthesia Error Cause a Brain Injury?
The brain requires a continuous supply of oxygenated blood. Even a brief interruption can damage brain cells. The longer the brain is deprived of oxygen, the greater the risk of permanent neurological injury.
Two terms commonly associated with anesthesia-related brain injuries are:
- Hypoxic brain injury: The brain receives an inadequate amount of oxygen.
- Anoxic brain injury: The brain experiences a complete or nearly complete loss of oxygen.
During surgery, anesthesia providers are responsible for monitoring the patient’s oxygen saturation, blood pressure, heart rate, breathing, carbon dioxide levels, and other vital signs. If a dangerous change is not detected or treated quickly, the patient may suffer cardiac arrest, respiratory arrest, stroke, or brain damage.
Common Anesthesia Errors That May Lead to Brain Damage
Anesthesia malpractice can occur before, during, or after a surgical procedure. Potential errors include the following.
Administering Too Much Anesthesia
An excessive dose of anesthesia can dangerously suppress breathing, lower blood pressure, or interfere with heart function. These complications may reduce the flow of oxygenated blood to the brain.
The correct dosage can depend on numerous factors, including the patient’s:
- Age
- Weight
- Medical history
- Existing health conditions
- Current medications
- Allergies
- Alcohol or drug use
- Type and anticipated duration of surgery
Failing to consider these factors may expose a patient to an avoidable risk of overdose and brain injury.
Administering Too Little Anesthesia
Insufficient anesthesia can result in anesthesia awareness, in which a patient becomes conscious during surgery. Although awareness does not necessarily cause a physical brain injury, it can result in severe psychological trauma, including anxiety, nightmares, depression, and post-traumatic stress disorder.
Too little anesthesia may also cause the patient to move or experience physiological stress during the operation, potentially contributing to other surgical complications.
Failure to Monitor Oxygen Levels
Pulse oximetry and other monitoring equipment allow the anesthesia team to identify falling oxygen levels. A failure to monitor the patient, recognize an abnormal reading, investigate an alarm, or take corrective action may allow oxygen deprivation to continue.
In some cases, providers may ignore or silence an alarm because they assume it is caused by faulty equipment. If the alarm reflects a genuine medical emergency, the delay can have devastating consequences.
Intubation and Airway Management Errors
General anesthesia often requires the placement of a breathing tube. Intubation errors may prevent oxygen from reaching the lungs.
Examples of possible airway-management mistakes include:
- Placing the breathing tube in the esophagus instead of the trachea
- Failing to confirm proper tube placement
- Using an improperly sized tube
- Failing to recognize that the tube has moved or become disconnected
- Delaying intubation when a patient cannot breathe independently
- Failing to manage a difficult airway appropriately
- Failing to respond to an airway obstruction
- Removing the breathing tube prematurely
Because airway problems can quickly become life-threatening, anesthesia professionals must recognize and correct them without unnecessary delay.
Failure to Address Low Blood Pressure
The brain needs adequate blood flow as well as oxygen. If a patient’s blood pressure becomes dangerously low, the brain may not receive enough oxygenated blood.
Anesthesia providers must monitor blood pressure and respond appropriately to significant changes. Depending on the circumstances, treatment may include medication, intravenous fluids, blood products, changes in anesthesia, or other emergency measures.
Failure to Review the Patient’s Medical History
Before administering anesthesia, the healthcare team should evaluate the patient’s medical history and individual risk factors. This assessment may include reviewing:
- Heart or lung disease
- Prior reactions to anesthesia
- Allergies
- Sleep apnea
- Neurological conditions
- Prescription medications
- Over-the-counter medications
- Supplements
- Alcohol or recreational drug use
- Recent food or liquid consumption
Failing to obtain or consider important medical information may lead to an inappropriate anesthesia plan, a dangerous drug interaction, or inadequate preparation for a foreseeable complication.
Medication and Drug-Interaction Errors
Anesthesia frequently involves multiple medications. A mistake involving the type, dose, timing, or method of administration can cause respiratory depression, abnormal blood pressure, cardiac complications, or other emergencies.
Potential medication errors include:
- Administering the wrong drug
- Confusing medications with similar labels
- Giving an incorrect dosage
- Failing to account for another medication
- Using a drug to which the patient has a documented allergy
- Failing to monitor the patient after administering a high-risk medication
Failure to Respond to an Emergency
Some anesthesia complications cannot be prevented. Nevertheless, the anesthesia team must be prepared to recognize and manage emergencies.
A potentially manageable complication may result in permanent brain damage if providers delay resuscitation, fail to restore the patient’s airway, fail to give appropriate medications, or do not follow established emergency procedures.
Inadequate Monitoring After Surgery
The anesthesia provider’s responsibilities do not always end when the operation is completed. Patients may remain vulnerable to respiratory depression, airway obstruction, aspiration, and other complications in the post-anesthesia care unit.
Premature transfer, inadequate monitoring, or failure to recognize postoperative deterioration can result in oxygen deprivation and brain injury.
What Are the Symptoms of an Anesthesia-Related Brain Injury?
Symptoms depend on the area of the brain affected, the duration of oxygen deprivation, and the severity of the damage. Signs may appear immediately, or their full extent may become clearer during the days and weeks following surgery.
Possible symptoms include:
- Memory loss
- Confusion or disorientation
- Difficulty concentrating
- Speech or language problems
- Changes in personality or behavior
- Loss of coordination
- Muscle weakness
- Difficulty walking
- Vision problems
- Seizures
- Problems swallowing
- Loss of fine motor skills
- Reduced awareness
- Coma
- Permanent cognitive disability
A severe brain injury may leave the patient unable to work, communicate, perform daily activities, or live independently.
Does a Bad Surgical Outcome Prove Anesthesia Malpractice?
No. A poor outcome alone does not establish medical malpractice. The patient generally must prove that a healthcare provider failed to meet the prevailing professional standard of care and that this failure caused or substantially contributed to the injury.
In an anesthesia brain-injury case, the central questions may include:
- What standard of care applied under the circumstances?
- Did the anesthesia provider or another healthcare professional violate that standard?
- Did the violation cause oxygen deprivation or another event that injured the brain?
- What physical, cognitive, emotional, and financial harm resulted?
These issues usually require opinions from qualified medical experts.
Who May Be Liable for an Anesthesia-Related Brain Injury?
Liability depends on who made the error, the employment relationships among the providers, and the circumstances of the procedure. Potentially responsible parties may include:
- An anesthesiologist
- A certified registered nurse anesthetist
- A surgeon
- Nurses or recovery-room personnel
- An anesthesia practice
- A hospital
- An ambulatory surgical center
- Another healthcare organization
- A medical-device manufacturer, if defective equipment contributed to the injury
More than one party may share responsibility. For example, an anesthesia provider may fail to recognize falling oxygen levels while a hospital may have supplied defective monitoring equipment or inadequately trained personnel.
What Evidence May Help Prove an Anesthesia Malpractice Claim?
Anesthesia cases often require a detailed review of records created before, during, and after the procedure. Important evidence may include:
- Pre-anesthesia evaluation records
- The anesthesia plan
- The anesthesia record or flow sheet
- Electronic vital-sign data
- Oxygen-saturation and carbon-dioxide readings
- Medication administration records
- Intubation and airway-management documentation
- Operating-room records
- Post-anesthesia care records
- Code and resuscitation records
- Hospital policies and procedures
- Equipment maintenance records
- Imaging studies
- Neurology records
- Rehabilitation records
- Witness testimony
The anesthesia record may contain minute-by-minute information about medications, oxygen levels, blood pressure, heart rate, ventilation, and significant events. Electronic monitoring systems may preserve additional data that is not fully reflected in the printed chart.
A prompt investigation can be important because some electronic data, equipment information, surveillance recordings, and staff recollections may not remain available indefinitely.
The Role of Medical Experts
Expert testimony is usually essential in an anesthesia malpractice case. An expert may evaluate whether the anesthesia plan was appropriate, whether the patient was properly monitored, and whether the providers responded reasonably to signs of distress.
Depending on the facts, the case may require experts in:
- Anesthesiology
- Critical-care medicine
- Neurology
- Neuroradiology
- Neuropsychology
- Physical medicine and rehabilitation
- Life-care planning
- Vocational rehabilitation
- Economics
Experts may also help distinguish a brain injury caused by oxygen deprivation during anesthesia from one caused by an unrelated medical condition.
What Compensation May Be Available?
An anesthesia-related brain injury can create a lifetime of medical and financial needs. Recoverable damages will depend on the evidence and the circumstances of the case, but they may include:
- Past and future medical expenses
- Hospital and rehabilitation costs
- Physical, occupational, and speech therapy
- Medication and medical equipment
- In-home nursing or attendant care
- Home and vehicle modifications
- Lost wages
- Loss of future earning capacity
- Pain and suffering
- Mental anguish
- Disability
- Loss of enjoyment of life
- Loss of consortium or companionship
If the patient dies, the personal representative of the estate may be able to bring a wrongful death claim for the benefit of eligible survivors. The damages available depend on the survivor’s relationship to the deceased and other case-specific factors.
How Long Do You Have to File an Anesthesia Malpractice Lawsuit in Florida?
Florida generally requires a medical malpractice action to be filed within two years of the incident or within two years of when the incident was discovered—or reasonably should have been discovered. Florida law also establishes a four-year statute of repose in many cases, subject to limited exceptions involving matters such as fraud, concealment, intentional misrepresentation, and certain claims involving young children.
These deadlines are not always straightforward. The date of a brain injury may be known, but the patient or family may not immediately know that an anesthesia error contributed to it. Different requirements may also apply when the healthcare provider is a government-owned facility or public entity.
Florida medical malpractice claims ordinarily require a presuit investigation and formal notice before a lawsuit may be filed. The claimant must comply with specific statutory procedures, which can include obtaining a supporting opinion from a qualified medical expert.
Because investigating the claim and completing the presuit process takes time, patients and families should not wait until a deadline is approaching to seek legal advice.
What Should You Do If You Suspect an Anesthesia Error?
If you or a loved one suffered an unexpected brain injury during or after surgery, consider taking the following steps:
- Obtain appropriate medical care. Immediate treatment and rehabilitation should remain the first priority.
- Request the complete medical record. Ask for records from the hospital, surgical center, anesthesia practice, surgeon, emergency department, and rehabilitation providers.
- Preserve documents. Keep discharge instructions, medical bills, insurance statements, photographs, correspondence, and notes regarding conversations with healthcare personnel.
- Document the patient’s condition. Maintain a record of cognitive, physical, behavioral, and emotional changes.
- Avoid signing releases without advice. A hospital or insurer may request statements, authorizations, or settlement documents.
- Consult a medical malpractice lawyer promptly. An attorney can evaluate the deadlines, identify potential defendants, preserve evidence, and arrange an expert review.
