background: hemodynamic instability is common during tracheal intubation. the primary purpose of the present study is to evaluate the effect of different doses of remifentanil added to propofol on the hemodynamic profiles during tracheal intubation. methods: ninety patients, 40 to 70 years old, undergoing coronary artery bypass graft surgery under general anesthesia were randomly allocated into...

background: etomidate and propofol are common anesthetic agents. previous studies say that etomidate can be used in patients with limited hemodynamic reserve and propofol can lead to more hemodynamic instabilities. th is study was performed to explore the cardiovascular response during the induction of anesthesia with etomidate or for comparison, propofol in elective orthopedic surgeries. mater...

introduction: the bed nucleus of the stria terminalis (bst) is a limbic structure which is involved in cardiovascular regulation and baroreflex modulation. the presence of cholinergic synaptic terminalis with high level of muscarinic receptors in the bst has been demonstrated. this study was performed to find the role of the cholinergic muscarinic receptor in cardiovascular response and baroref...
