Effect of phenylephrine and ephedrine bolus treatment on blood pressure, cardiac output, and cerebral oxygenation

Following phenylephrine administration, even though blood pressure is increased, both cardiac output and cerebral oxygenation are decreased. In contrast, both cardiac output and cerebral oxygenation are maintained after ephedrine administration which also leads to an increase of blood pressure. It implies that different vasoactive drugs exert different impacts on systemic circulation and organ perfusion/oxygenation. The mechanisms behind these observations have been explored and the clinical significance awaits to be determined.

Integrated multifactorial CBF regulation

"The proposed conceptualization integrating various CBF-regulating mechanisms within the framework of cerebral autoregulation has important clinical implications. The habitual thinking that how the brain is perfused is merely dependent on the blood pressure should be abandoned. The autoregulatory curve should be regarded as a dynamic process, meaning that its shape, plateau, and the lower and upper limits may change depending on the integrated effect of nonpressure but CBF-regulating mechanisms including the CO. For a given value of blood pressure, even though it is deemed clinically acceptable, the CBF may be either higher or lower than that estimated by the traditional autoregulatory curve. Therefore, the management of CBF should be guided by a multifactorial but integrated framework of CBF regulation, especially in patients who are at risk of cerebral ischemia."
