Human Error
Communication breakdowns played a role in 43% of anesthesia-related incidents, per Anesthesia & Analgesia. Includes failure to monitor, inattention, rushing, unfamiliarity with equipment, fatigue, or non-adherence to protocols.
Mechanical Error
Ventilators, anesthesia machines, breathing circuits, airway devices, laryngoscopes, and monitoring systems must be properly maintained.
Medication Errors
The British Journal of Anaesthesia found medication errors happen in about 1 out of every 20 anesthesia cases. Overdosing and excessive sedation are particularly dangerous.
Airway Management Errors
Incorrect intubation, airway blockage, insufficient ventilation — can cause hypoxia, respiratory distress, or airway injury.
Inadequate Monitoring
Delay in recognizing changes to heart rate, blood pressure, oxygen levels, or respiratory function increases the risk of serious harm.
Anesthesia Awareness
Patient regains consciousness during surgery but is unable to move or speak due to paralysis. Though rare, this experience can be deeply traumatic.
General Anesthesia Complications
Strokes, heart attacks, lung infections, anaphylaxis, spinal cord injuries, ventilator dependence, death. Non-fatal injuries include eye injuries, sore throat, vocal cord damage, and peripheral nerve damage from improper positioning.
Spinal & Epidural Complications
Spinal infections, nerve injury, seizures, allergic reactions, bleeding around the spinal area, urinary retention, blood pressure drops, intense headaches.
