Prophylactic infusion of norepinephrine enhances hemodynamic stability during propofol induction and early intubation period in elderly patients: a double-blind randomized placebo-controlled study

Background The induction of general anesthesia with propofol often results in hypotension, primarily attributed to decreased cardiac index (CIx) among elderly patients. Norepinephrine (NE) is typically used to manage anesthesia-induced hypotension. We hypothesized that NE attenuates the reduction in CIx while preservin...
