Filter by:Rationale: The rapidly increasing number of elderly (≥ 65 years old) with traumatic brain injury (TBI) is accompanied by substantial medical and economic consequences. An intracranial hematoma, specifically an acute subdural hematoma (ASDH), is the most common injury in elderly with TBI. The surgical versus conservative treatment of this patient group remains an important clinical and moral dilemma, since it is in most cases unclear which treatment leads to a better outcome for the patient. Current guidelines are not based on high-quality evidence and compliance is low, allowing for large treatment variation in both Belgium and the Netherlands for patients with a traumatic ASDH. In addition, elderly are underrepresented in scientific TBI literature and are therefore not included in current guidelines or prognostic models, leading to major uncertainty in (neurosurgical) decision-making for this group. As participants in two large TBI research projects (CENTER-TBI, Net-QuRe), the investigators observe that the uncertainty regarding treatment of elderly with a traumatic ASDH will not be solved by the current ongoing studies. Therefore, they recognize the necessity of undertaking a prospective, randomized, multicenter trial on the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly with a traumatic ASDH. Objective: To compare the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly patients with a traumatic ASDH. Study design: A prospective, pragmatic, multicenter, randomized controlled trial (RCT). Study population: Patients ≥ 65 years with at first presentation a GCS ≥ 9 and a traumatic ASDH >10 mm or a traumatic ASDH <10 mm and a midline shift >5 mm, or a GCS < 9 with a traumatic ASDH <10 mm and a midline shift <5 mm without extracranial explanations for the comatose state, for whom clinical equipoise exists regarding the preferred treatment. Intervention: Patients are randomized to either early surgical hematoma evacuation (A) or conservative management on the ICU or the ward (B). In case of neurological deterioration during conservative management, delayed surgery can be performed. The exact neurosurgical technique will be left to the discretion of the surgeons. Main study parameters/endpoints: Functional outcome after 1 year, expressed by the rating on the Extended Glasgow Outcome Scale (GOS-E) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Both treatment strategies are already used in current clinical practice as standard medical care. Therefore, there are no extra risks for patients participating in the study compared to patients outside the study. Study participation adds a minimal burden of three follow-up evaluations by visit in the first year (at 3, 6 and 12 months) and subsequent yearly evaluations by phone or postal until five years after the injury. Future elderly patients with a traumatic ASDH will benefit mostly from this study's results.
Subdural haematoma is a common neurosurgical condition that results in different levels of neurological deficits in patients. It can be further classified into acute and chronic, which have different pathophysiology. Acute haematoma is a common result of traumatic injuries involving the tearing of the bridging veins, while chronic subdural haematoma can be both a result of traumatic injuries or recurrence following surgical management of the acute counterpart. For symptomatic patients, they are often surgically managed by haematoma drainage via burr-hole drainage and craniotomy. Recurrent bleeding following close monitor or surgical evacuation of haematoma is however very high. Recent studies approximate the recurrence rate of 2%-33.3%. Recent evidence suggests the angiogenesis of middle meningeal arteries (MMA) in response to inflammation and healing process contributes to the development of chronic subdural haematoma, and its high recurrence chance. Several studies have looked into the use of middle meningeal artery embolization to halt the bleeding of a chronic subdural haematoma, and have found promising results in terms of haematoma reduction and prevention of surgical rescues.
The primary objective of this study is to determine the effectiveness of the NICO BrainPath™ hematoma evacuation system for patients between the ages of 18 and 80 years old with an intracerebral hematoma. Effectiveness will be defined as the ability to achieve either 70% reduction of intracranial hematoma or to achieve <15 ml residual hematoma volume following surgery. Additionally, the study aims to compare the mortality and complication rate of patients who undergo minimally invasive, navigation guided endoport based evacuation of intracerebral hematoma with NICO BrainPath™ System as compared to non-operative, supportive standard of care. The study is a prospective, non-randomized cohort study. 50 patients will be enrolled in Group A (NICO BrainPath™ system) and 50 patients will be matched retrospectively of similar diagnosis, undergoing standard of care from Epic). 50 patients will undergo minimally invasive, navigation guided endport based evacuation of intracerebral hematoma with NICO BrainPath™ System. The patient population receiving non-operative supportive care will be matched to the surgical patients based on age, gender, and location of hemorrhage.
This study will measure in children how much numbing medicine, lidocaine, is absorbed into the bloodstream after it is injected into a blood clot (hematoma) around a forearm fracture for pain control when the broken bone is moved back into place (fracture reduction). This is called a hematoma block and is commonly used in the Emergency Unit. To help with anxiety and to add additional pain control, nitrous oxide (laughing gas) is given while the lidocaine hematoma block is placed and continued during the fracture reduction. Advantages of using this technique for pain control instead of an intravenous anesthetic such as ketamine include faster recovery and discharge home, and longer pain control. Of concern, if too much lidocaine is absorbed into the bloodstream, seizures and irregular heart beating may occur. Bloodstream concentrations of lidocaine after a hematoma block have been measured in only one study of 8 adults and found to be at significant but safe levels. No study has been published in children to measure bloodstream lidocaine levels when a hematoma block is used. Because children's bones are still growing and more metabolically active than adult bones, the investigators believe it is important to determine whether lidocaine blood levels in children are also at safe levels when using a standard lidocaine hematoma block for reduction of fractures. The investigators also want to determine whether bloodstream lidocaine levels correlate with type of fracture. The investigators also aim to determine if there is a difference in absorption pattern between different types of distal radius fractures, if there is a correlation between fracture type and systemic lidocaine absorption, and if there is a correlation between fracture type and ability to provide adequate pain and sedation control with lidocaine hematoma block/inhaled nitrous combination. The investigators believe blood lidocaine levels after hematoma block in children will peak at safe levels, but will be higher than those observed in adults.
Intra-articular fractures of the distal radius are common in urban populations and result in significant morbidity in terms of time away from work. Volar plating of the distal radius is a commonly used mode of surgical fixation of this fracture. The joint haematoma resulting from the fracture has been hypothesized to contribute to the post-injury disability. As such, this study aims to examine if the evacuation of the haematoma during volar plating results in superior functional outcomes at three months post surgery.
Our long-term objective is to evaluate the efficacy of curcumin (CC) in preventing a recurrence of chronic subdural hematoma (cSDH) following surgical evacuation. Recurrence is defined as an increase in total hematoma volume on the operated side compared to a post-operative day one CT scan with persistent or recurrent neurological symptoms. The investigators propose this pilot study to assess feasibility and obtain preliminary benefit assessment of the proposed therapeutic approach. Objective 1: To determine if the use of CC treatment reduces the total hematoma cavity volume over a 6-month interval, compared to a post-subdural drain removal CT scan. This evaluation is expected to offer sufficient evidence for a larger definitive trial. Objective 2: Study the effect of CC on interleukin-8 (IL-8)-induced disruption of endothelial permeability in vitro using human vascular endothelial cells. Central hypothesis: CC treatment prevents the re-accumulation of cSDH, which may occur by inhibition of IL-8 and allowing resolution of the total hematoma cavity volume over six months.
Non-traumatic intracerebral hemorrhage (ICH) affects approximately 100,000 Americans yearly. Up to 30-50% of ICH is fatal, and those patients who survive are often left with significant neurologic dysfunction. In the past, medical management (e.g., control of hypertension, reversal of antiplatelet or anticoagulants) had been the most effective treatment for these patients, given the morbidity and mortality associated with open surgical treatment for evacuation of ICH. However, recent trials have demonstrated that minimally invasive stereotactic neurosurgical procedures to evacuate ICH are safe and result in improved outcomes for these patients. Initial attempts to evaluate the efficacy of surgical evacuation of ICH found no significant difference between medical management and standard craniotomy for surgical evacuation. Indeed, open surgery was often discouraged for these patients due to the significant morbidity and mortality associated with the surgical procedure itself. However, research has demonstrated that minimally invasive, image guided stereotactic frame-based and frameless methods are effective and safe for the placement of catheters for clot aspiration and fibrinolytic therapy of ICH in the basal ganglia and other deep seated regions. Larger randomized controlled trials have demonstrated that these minimally invasive approaches also offer clinical benefit for these patients.

Cerebral edema is seen heterogenous group of neurological disease states that mainly fall under the categories of metabolic, infectious, neoplasia, cerebrovascular, and traumatic brain injury disease states. Regardless of the driving force, cerebral edema is defined as the accumulation of fluid in the brain's intracellular and extracellular spaces. This occurs secondary to alterations in the complex interplay between four distinct fluid compartments within the cranium. In any human cranium; fluid is contained in the blood, the cerebrospinal fluid, interstitial fluid of the brain parenchyma, and the intracellular fluid of the neurons and glia. Fluid movement occurs normally between these compartments and depends on specific concentrations of solutes (such as sodium) and water. In brain-injured states, the normal regulation of this process is disturbed and cerebral edema can develop. Cerebral edema leads to increased intracranial pressure and mortality secondary to brain tissue compression, given the confines of the fixed-volume cranium. Additionally, secondary neuronal dysfunction or death can occur at the cellular level secondary to the disruption of ion gradients that control metabolism and function. While studies utilizing bolus dosing of hyperosmolar therapy to target signs or symptoms of increased intracranial pressure secondary to cerebral edema are numerous, there is a paucity of studies relating to continuous infusion of hyperosmolar therapy for targeted sustained hypernatremia for the prevention and treatment of cerebral edema. The investigators hypothesize that induced, sustained hypernatremia following traumatic brain injury will decrease the rate of cerebral edema formation and improve patient outcomes.
