Active clinical trials for "Subarachnoid Hemorrhage"

The purpose of this study is to explore two currently accepted methods of intracranial pressure (ICP) management through cerebral spinal fluid (CRF) drainage for patients diagnosed with subarachnoid hemorrhage (SAH). This is a randomized observational study of two physician-prescribed approaches to managing ICP monitoring and CSF drainage for SAH patients. The study will enroll only those patients who have ICP monitoring. Because this is an observational study, there are no physical risks to the patient, the only risk is loss of confidentiality.

The general objective of the comaScore project is to provide an external validation of the accuracy of the comaScore, a score derived from magnetic resonance imaging (MRI), to predict 1 year outcome of patients unresponsive to simple orders after traumatic brain injury (TBI), aneurysmal subarachnoid hemorrhages (aSAH) and cardiac arrest (CA) in the day 7 - day 45 period post brain injury.

The purpose is, in patients with aneurysmal subarachnoid haemorrhage in the early phase after ictus, to examine the following: The effect of spontaneous and induced changes on the brain's static and dynamic autoregulation calculated by transcranial Doppler (TCD), ICP and MAP (primary purposes) and ICP and PbtO2; The effect of mild hyper- and hypocapnia as well as of mild hyper- and hypoxia on the brain's static and dynamic autoregulation, ICP and PbtO2; The relationship between brain autoregulation, mild hyper- and hypocapnia, as well as of mild hyper- and hypoxia and metabolism in microdialysate on the one hand and the occurrence of DCI during hospitalization and poor neurological outcome one year after ictus on the other.

Hypothesis: During severe brain trauma (injury, surgery) the ensuing inflammatory response in the central nervous system (CNS) results in a decrease in the expression of the transporter protein p-glycoprotein (PGP) in the blood brain barrier. This loss results in the penetration into the brain of certain drugs that are normally excluded by the transporter protein. In this study the working hypothesis is that the agitation observed in patients with CNS trauma treated with morphine is related to the inflammation evoked loss of PGP in the blood brain barrier and the accumulation of the morphine metabolite 3-morphine glucuronide.

The purpose of this study is to determine the feasibility of prospectively enrolling and randomizing patients with aneurysmal subarachnoid hemorrhage (aSAH) to receive levetiracetam or not to receive levetiracetam, and documenting in-hospital and follow-up clinical variables.

The lack of a precise diagnostic technique for cerebral vasospasm associated with traumatic brain injury (TBI) limits the ability to detect and treat this phenomenon. Surveillance Transcranial Doppler ultrasonography (TCD) is the main medical instrument that is utilized to monitor radiographic vasospasm following TBI, yet has its drawbacks such as inaccuracy, highly operator dependent and more. HS-1000 device, an investigational vasospasm detection device, has the potential to safely diagnose and assess vasospasm with minimal discomfort to patients, allowing a new modality for vasospasm measurement tool. We aim to evaluate the correlation between the collected and analyzed data from the HS-1000 device and the clinical findings from the TCD tests post-subarachnoid hemorrhage (SAH) patients.

The study aims to evaluate the suitability of the SOFA score implemented by the Sepsis 3 guideline to detect sepsis in patients suffering from subrarachnoid hemorrhage.

Intracranial pressure (ICP) monitoring is the most common neuromonitoring modality used in neurocritical care units (NCCU) around the world. Uncertainties remain around intracranial pressure monitoring both in traumatic and non-traumatic brain injury, and variation in clinical practice of intracranial pressure monitoring exists between neurocritical care units. The objectives of the study will explore intracranial pressure monitoring variation in practice to prioritise uncertainties in the clinical management of critical care patients with acute brain injury and support further collaborative hypotheses-based prospective studies.

The main purpose of this study is to analyse the on-going coagulation process after aSAH. For investigation the investigators use the rotational thromboelastometry (ROTEM) which is a point-of-care test using a variety of activators to provide a targeted and a dynamic analysis of coagulation cascade. This is a prospective, observational clinical study done in 16 aSAH patients treated in Tampere University Hospital intensive care unit and 16 control patients (elective craniotomy due to non-ruptured intracranial aneurysm.

This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.
