Key result
Isoflurane yields higher MAP and alters regional cerebral blood flow versus halothane in dogs.
Why the study?
The cerebral and systemic circulatory effects of halothane and isoflurane at different MAC concentrations were compared to evaluate their impact on cerebral blood flow and cardiovascular parameters.
Does isoflurane compared to halothane alter cerebral and systemic hemodynamics in mongrel dogs?
Comparison
Isoflurane at 1.3 MAC (1.5%) or 1.7 MAC (2%) vs halothane at 1.3 MAC (1%) or 1.7 MAC (1.3%)
Design
Comparative preclinical study with repeated measurements

Premature for neurosurgical anesthesia protocols; leaves open human validation of cerebral hemodynamic effects.
Does isoflurane compared to halothane alter cerebral and systemic hemodynamics in mongrel dogs?
Isoflurane maintains higher mean arterial pressure and produces differential regional cerebral blood flow compared to halothane, suggesting potential advantages for neurosurgical procedures.
Boarini et al. (1984) studied Anesthesia (n=24). Isoflurane vs. Halothane was evaluated on Cerebral and systemic circulatory effects (blood flow and cardiovascular measurements). In mongrel dogs, isoflurane produced higher mean arterial pressure and different regional cerebral blood flow patterns compared to halothane, suggesting potential advantages for neurosurgery.
