Phenylephrine in aortic stenosis
WebApr 30, 2024 · Aortic valve stenosis (AS) is the most frequent type of valvular heart disease requiring valve replacement. 1,2 While AS typically is secondary to degeneration of a tricuspid aortic valve in older patients, bicuspid aortic valve is the most common cause of AS in younger patients. WebAims: A systematic literature review comparing the efficacy of ephedrine and phenylephrine for the management of spinal anesthesia-induced hypotension during Cesarean sections (C-sections) was published in 2002. A number of well-designed trials with controversial results have been published afterward. Therefore, an updated meta-analysis was necessary.

WebUse an alpha-1 agonist (eg. phenylephrine) – to keep pressures adequate without an increased HR. Avoid spinal anesthesia – due to sympathectomy (reduced SVR and hypotension). Epidural anesthesia CAN be done – but relies heavily on the anesthesia provider’s judgement Keep HR at a conservative high – typically between 70-80.
