Background Systemic vascular resistance (the ratio of mean aortic pressure [AP] and mean
aortic blood flow [AQ]) does not completely describe left ventricular (LV) afterload because of …

The combination of fentanyl and diazepam significantly decreases systemic vascular
resistance and blood pressure. We attempted to elucidate the reason the combination of …

Background The mechanisms producing hemodynamic changes during epidural anesthesia
are incompletely understood. The role of capacitance changes in the splanchnic venous bed …

To investigate the impact of fentanyl on the carotid chemoreceptor reflex, nine mongrel dogs
were permanently monitored with electromagnetic flow transducers around the right …

Background and objective: The safety of hypotension induced by sevoflurane and
splanchnic organ blood flow remains to be clarified. The aim was to investigate the effects of …

We have studied the effects of midazolam and flumazenil on the carotid sinus baroreflex, by
examining mean arterial pressure (MAP) and heart rate (HR) responses to partial or …

Vascular effects of general anesthesia are usually described by changes in vascular
resistance, which assumes a linear pressure-flow relationship passing through the zero-flow …

Data have been presented showing that certain general anaesthetic agents such as
halothane decrease the spontaneous activity of the rabbit anterior mesenteric portal vein …

Cardiovascular homeostasis is dependent on the efficient performance of the effector
organs, ie the vascular smooth muscle and the heart. Besides inherent activity and local …

In chloralose‐anaesthetized dogs the carotid sinuses were bilaterally perfused with blood
from a femoral artery, either at systemic arterial pressure through a direct by‐pass or with a …
