Final answer:
The percentage of anesthetic deaths attributed to difficult and failed airway management is approximately 30%. Despite advances in anesthesia, airway management continues to be a critical aspect for patient safety.
Step-by-step explanation:
The percentage of anesthetic deaths attributed to difficult and failed airway management is widely accepted to be around 30%. Airway management is a critical aspect of anesthesia, and difficulties in this area can lead to serious complications, including hypoxia and death. While anesthetic techniques and monitoring have advanced considerably, adequately managing the airway remains a key factor in patient safety during anesthesia.
