Key result
Halothane dose-dependently and non-competitively reduced the pressor responses to diphenyleneiodonium in rats by inhibiting sympathetic nervous system activities.
Why the study?
Does halothane inhibit the pressor effect of diphenyleneiodonium in rats?
Population
Rats (conscious and anesthetized)
Comparison
Halothane (0.5-1.25%) vs Conscious state and other anesthetics

Halothane may confound DPI pressor responses under anesthesia in rats; hypothesis-generating and leaves open translation to conscious models.
Does halothane inhibit the pressor effect of diphenyleneiodonium in rats?
Halothane abolishes the pressor response to DPI by inhibiting sympathetic nervous system activation, highlighting the need to consider anesthetic influences when evaluating vasoactive agents.
Wang et al. (1993) studied this question. Halothane vs. Conscious state / other anesthetics was evaluated on Pressor response (mean arterial pressure) to diphenyleneiodonium. Halothane dose-dependently and non-competitively reduced the pressor responses to diphenyleneiodonium in rats by inhibiting sympathetic nervous system activities.
