1. Introduction: Global cerebral ischaemic-reperfusion brain injury following cardiac arrest (CA) can lead to intracranial hypertension and, occasionally, acute brain swelling. Even small increases in brain volume due to edema can result in harmful increases in intracranial pressure due to the
Introduction:
Hyperventilation has been used for intraoperative brain relaxation for decades, Interestingly, this common practice is not based on robust evidence .
The mechanism of brain relaxation secondary to hyperventilation is attributed to the hypocapnia induced cerebral vasoconstriction and
Spontaneous aneurysm subarachnoid hemorrhage (SAH) occurs annually in approximately 400 people in Denmark. SAH is most commonly seen in younger (median age 56 years) and women (71%), have a high mortality (21-44%) and result in a poor neurological outcome in about 50% of patients. Due to the
Background Cerebral autoregulation is generally considered to maintain cerebral blood flow (CBF) if mean arterial pressure (MAP) is between 60 and 150 mmHg. Yet, it is controversial whether there is a plateau for CBF. Thus, blood velocity of the middle cerebral artery (MCA Vmean), as an index of
Mechanical ventilation (MV) in intensive care units (ICUs) essential in the management of respiratory failure, can result in respiratory dysfunction and inspiratory muscle weakness. Like any other striated muscle, respiratory muscle mass is affected by contractile inactivity. In fact, the
Background: In 1894 William Osler, MD, said: "You are as old as your arteries." A number of recent studies have confirmed this prescient proclamation. Vascular rather than chronological age is the best predictor of adverse cardiovascular events and mortality from coronary insufficiency, ischemia,
Background General anaesthesia reduces blood pressure, but cerebral autoregulation is considered to maintain its blood flow if mean arterial pressure (MAP) is between 60-150 mmHg. Thus, vasoactive medication is administered to treat anaesthesia-induced hypotension if MAP decreases to below
Research Plan
This study will be conducted at Mount Sinai Hospital. Patients will be recruited by reading the operating room schedule in advance and contacting patients over the phone to explain the study, risks and benefits, and obtain informed consent prior to admission to the hospital.
Objective
The main goal of this phase 1 clinical trial was to evaluate the safety of an autologous mesenchymal stem cell (MSC) application as therapy for drug-resistant symptomatic epilepsy in a one-center study. It is well known that drug-resistant symptomatic epilepsy is a dramatically invalidating disorder
METHODS Study Design This prospective observational cohort study, in adult patients who underwent craniotomy for supra or infratentorial surgery as elective or emergency procedure, was approved by the University of Rome "Sapienza", Policlinico Umberto I hospital, Institutional Review Board (2665,
80 patients will be divided in two equal groups (Group 1: to receive 20% mannitol 0.7 g/kg or Group 2: 1.4 g/kg).
The anesthetic technique and monitoring will be standardized. The administration of mannitol will start following the induction of general anesthesia. The infusion will be given
