Multi-Modal Assessment of Cerebral Hemodynamics in Resuscitated Out-of-Hospital Cardiac Arrest Patients: A Case-Series

Life
We assessed the feasibility of concurrent monitoring of cerebral hemodynamics in adult, comatose out-of-hospital cardiac arrest (OHCA) patients admitted to the National University Heart Centre Singapore from October 2021 to August 2023.

Effects of the intraoperative application of dexmedetomidine on hemodynamics and cerebral oxygen metabolism of patients with cerebrovascular malformations

BIO Web of Conferences, 2017
Circulatory stability of patients with cerebrovascular malformations during the surgery is critical to their prognosis. Anesthesia-induced intubation, tumor separation, clamping and other operations may cause severe fluctuations in blood pressure and ...

Eyeballing stroke: Blood flow alterations in the eye and visual impairments following transient middle cerebral artery occlusion in adult rats

Cell Transplantation, 2020
Middle cerebral artery occlusion in rodents remains a widely used model of ischemic stroke. Recently, we reported the occurrence of retinal ischemia in animals subjected to middle cerebral artery occlusion, owing in part to the circulatory juxtaposition ...

The Effects of Brovincamine on the Common Carotid Hemodynamics in Patients with Cerebral Circulatory Insufficiency

Neurosonology, 1989
This study was performed to clarify the effects of brovincamine on the common carotid hemodynamics in patients with cerebral circulatory insufficiency.A total of 38 patients including 14 males and 24 females were enrolled in this study. Their ages ranged from 55 to 84 years old and the mean age was 72 years old.
