Effects of intravenous anesthetics on normal and passively sensitized human isolated airway smooth muscle.

abstract：:Anesthetic exposure is usually necessary but rarely sufficient to the conduct of therapy. Consequently, there is a natural abhorrence of any worsening of a patient's condition secondary to the administration of anesthesia, which offers the patient no direct benefit. Highly safe anesthesia is a necessary precondition...
