WebFrequently used phenylephrine can lead to baroreceptor-mediated reflex bradycardia. The aim of the present study was to compare a fixed-rate prophylactic norepinephrine infusion to a fixed-rate prophylactic phenylephrine infusion during elective cesarean section under combined spinal-epidural anesthesia. Materials and methods: Webhexamethonium. Thus, the hypotension and bradycardia produced by the Akt inhibitor is primarily due to blockade of nAchRs in autonomic ganglia. This finding highlights the importance of evaluating the ANS for cardiovascular effects associated with new chemical entities as wellas suggesting a novel direct effect of an Akt inhibitor on nAchRs.
WebPhenylephrine is an alpha 1 agonist with very little beta effect. Its major action is systemic and pulmonary arterial vasoconstriction, increasing SVR and systemic arterial pressure (systolic, diastolic, and mean). Reflex bradycardia can occur. The increase in pulmonary artery pressure is less pronounced than the increase in aortic pressure.
