插管後血壓掉的原因

Teaching topics from the New England Journal of Medicine - Vol. 358, No. 2, January 10, 2008

Q: How could intubating a patient exacerbate a circulatory shock state?
  1. Positive-pressure ventilation reduces the pressure gradient for venous return.
  2. Many anesthesia-induction agents may exacerbate shock by means of either centrally medicated sympatholysis or direct vasodilatation.
  3. PEEP use.
