About Anesthesia Errors
Anesthesia errors involve mistakes made before, during, or after the administration of anesthesia that result in patient harm. These errors can lead to devastating consequences including brain damage from oxygen deprivation, awareness during surgery, nerve damage, or death. Because anesthesia involves carefully managing a patient's consciousness and vital functions, even small errors can have catastrophic and irreversible outcomes.

Common Examples of Anesthesia Errors
- •Administering too much anesthesia, leading to cardiovascular collapse or brain damage
- •Failure to properly intubate the patient, resulting in oxygen deprivation
- •Inadequate pre-operative evaluation of patient history, allergies, or airway anatomy
- •Failure to monitor vital signs during surgery, including oxygen saturation and blood pressure
- •Anesthesia awareness — patient regains consciousness during surgery but cannot move or communicate
- •Delayed recognition and treatment of malignant hyperthermia
- •Improper placement of regional anesthesia causing nerve damage or paralysis
Key Facts

- ✓Continuous intraoperative monitoring records, including capnography, pulse oximetry, and blood pressure logs, are critical evidence in anesthesia malpractice cases
- ✓The pre-anesthesia evaluation is a key area of scrutiny — failure to identify risk factors such as difficult airway, obesity, or drug allergies can establish negligence
- ✓Anesthesia awareness affects an estimated 1–2 per 1,000 patients under general anesthesia and can cause lasting psychological trauma including post-traumatic stress disorder
- ✓Cases may involve anesthesiologists, nurse anesthetists (CRNAs), or the supervising physician, depending on the care model and state regulations
- ✓Washington provides plaintiffs the later of 3 years from the act or 1 year from discovery, giving additional time to file.
