Yes. When an anesthesia provider fails to track a patient’s oxygen, breathing, and heart function, the patient can suffer permanent brain damage within minutes. Our experienced Belleville medical malpractice lawyers at The Cates Law Firm help families hold negligent providers accountable.
How Does Poor Anesthesia Monitoring Damage the Brain?
Anesthesia slows breathing. A patient can lose consciousness within 15 seconds of low oxygen, and brain cells begin to die after four minutes or longer. The American Society of Anesthesiologists requires qualified personnel in the room throughout every anesthetic and continual evaluation of oxygenation, ventilation, circulation, and temperature.
What Kind of Monitoring Failures Lead to Injury?
- Leaving the patient unattended or distracted
- Ignoring or silencing alarms
- Skipping pulse oximetry or capnography
- Missing an airway problem, such as a misplaced breathing tube
- Responding late to falling oxygen levels
An American Society of Anesthesiologists closed claims review found that additional monitors could have prevented about one-third of negative outcomes. A later analysis found that situational awareness errors contributed to more than 75% of death and brain injury claims, and failure to recognize breathing problems drove most of the perception errors.
What Are the Warning Signs of Oxygen Deprivation?
Confusion, disorientation, slurred speech, and seizures can signal a brain injury. Bluish or gray skin and lips also appear when oxygen runs low. Families should request the complete anesthesia record if these symptoms follow surgery.
Who Bears Responsibility?
Liability can fall on the anesthesiologist, nurse anesthetist, surgeon, hospital, or surgery center. Not every bad outcome proves negligence. You must show that the provider broke the standard of care and that the breach caused the injury.
What Compensation Can You Recover?
The Illinois Supreme Court struck down the state’s cap on “non-economic” damages in 2010, and “economic” damages never carried a cap. Recoverable losses include medical bills, lifetime care, lost income, and pain and suffering. Brain injury cases often demand lifelong care, so an accurate valuation matters.
How Long Do You Have to File?
Illinois law gives you two years from the date you knew or should have known of the negligence, with a four-year outer limit. Injured minors generally have eight years, but no later than age 22. Your lawyer must also file an affidavit and a health professional’s report with the complaint.
How Much Does The Cates Law Firm Charge?
The Cates Law Firm offers free consultations. In most cases, the firm charges no fee unless you recover compensation. The firm advances costs, such as expert witnesses, and asks for reimbursement only after a settlement or verdict.
Frequently Asked Questions (FAQs):
Can I sue if the provider followed the standards?
Not every injury results from negligence. A medical expert must review the records and find a reasonable cause for the claim.
What records should I request?
Request the full chart, including the anesthesia record, monitor data, and alarm logs.
Does the deadline change for a child?
Yes. A minor generally has eight years from the injury, but no later than the 22nd birthday.
