What should a healthy 66-year-old patient who had an MI 8 years ago be treated with for an extraction?

  1. General Anesthesia

  2. LA without vasoconstrictor

  3. LA + vasoconstrictor

  4. Sedation without LA

The correct answer is: LA + vasoconstrictor

A healthy 66-year-old patient who had an MI 8 years ago should be treated with local anesthesia (LA) + vasoconstrictor during an extraction. This is because the use of vasoconstrictor can help minimize bleeding and maintain blood pressure within a safe range during the procedure. General anesthesia is not necessary in this case, as it may carry higher risks for someone who had a previous MI. Using LA without vasoconstrictor may also result in excessive bleeding and increase the risk of complications. Sedation without LA is also not recommended as it may not provide adequate pain control during the extraction. Therefore, the most appropriate option for this patient would be using LA + vasoconstrictor.
