Filter by:Objectives: Ketamine is an effective, short-acting anesthetic drug, which does not decrease blood pressure. It is widely stated that Ketamine increases intracranial pressure (ICP), which prevents its use in many emergency situations, specifically in patients with traumatic brain injury (TBI) and with increased ICP. Based on previous clinical experience, we hypothesized that Ketamine decreases – rather than increases – ICP. Methods: Prospective, controlled, clinical trial. Children with ICP monitoring will receive a single Ketamine dose (1-1.5 mg/kg) either for increased ICP and/or before a potentially distressing activity. Hemodynamic variables, ICP and cerebral perfusion pressure (CPP) will be recorded 1 minute before and every minute for 10 minutes following Ketamine administration (Before/after design).
The overall purpose of this study is to compare the effects of mannitol and hypertonic saline on patients with increased intracranial pressure. The hypothesis being tested is that hypertonic saline is more effective in controlling increased intracranial pressure than mannitol.
The purpose of this study is to compare the effect of bolus of either sodium-lactate or mannitol on the evolution of intracranial pressure (ICP) during intracranial hypertensive episodes (IHE)
External ventricular catheters are used for intracranial pressure monitoring and temporary cerebrospinal fluid (CSF) drainage in neurosurgery. The incidence of ventriculostomy-related cerebrospinal fluid infections had been quoted as between 2.2% to 10.4% in the more recent literature. Previous prospective studies in the investigators' unit have shown that the use of dual antibiotics prophylaxis in patients with external ventricular drain was associated with decreased incidence of CSF infection but was complicated with opportunistic extracranial infections. The current practice is to cover with prophylactic dual antibiotics unless guided by microbiology results for all patients with external ventricular drain. In recent years, cerebrospinal fluid shunt catheters impregnated with antimicrobial agents have been available. Experimental studies have shown that they provide protection against staphylococcal aureus and coagulase-negative staphylococci strains for between 42 days and 56 days. Theoretically, they provide the antibiotic prophylaxis locally without the associated complications of systemic antibiotics. It is hypothesized that the use of antibiotic-impregnated catheters instead of systemic antibiotic prophylaxis will not increase the rate of cerebrospinal fluid infection, will decrease the rate of opportunistic/nosocomial infections and improves the overall outcome in these patients; that would convert into a reduction in treatment cost of these patients.
The purpose of this study is to investigate real time 3-D ultrasound imaging of the brain for the diagnosis and evaluation of stroke.
The specific aim of this research is to determine if the blood from brain-injured patients contains reproducible protein markers that appear prior to elevations in intracranial pressure (ICP).
This is a clinical study comparing the physiologic effects of two hypertonic solutions (mannitol, hypertonic saline) with a particular emphasis on changes in cerebral blood flow in patients with intracranial hypertension following serious traumatic brain injury (TBI).
