Filter by:Headaches associated with subarachnoid hemorrhage (SAH) cause severe pain. Headache management is complex, requiring a balance between pain control and preservation of neurological assessment. Sufficient pain control can be achieved with narcotics, however, these carry numerous undesirable side effects. Most critically, all narcotics can result in respiratory depression and sedation. For patients who present without neurological defects but debilitating pain, management is particularly challenging. The sedative effect of narcotics confounds the management of these patients by interfering with the neurological examination. Pain management is also a significant concern for patient's families as they observe suffering without full understanding of the importance of preserved mental status. In order to control the pain associated with SAH headaches, the use of narcotics is often required despite the risks. This standard therapy involves an IV bolus dose delivered by the provider regularly as needed for pain control. A common approach to reduce pain in other patient populations, including acute pain relief following major spine surgery, is patient controlled analgesia (PCA). With the PCA method, patients deliver low doses of narcotics through a pain pump with preset maximal doses and frequency of delivery. We hypothesize that this approach to pain relief for SAH headaches will result in lower pain scores, greater patient and family satisfaction scores, and increased patient safety with lower narcotic doses minimally interfering with neurological assessment.
Dexmedetomidine is a unique sedative medication able to provide sedation without causing respiratory depression and maintaining neurological functions. Patients having an acute ischemic stroke and need to undergo endovascular therapy require constant assessment of their neurological status prior, during and after the interventional procedure. In this study the investigators will compare the efficacy of Dexmedetomidine to other standard sedative medications in providing optimal sedative effect while maintaining neurological function.
This is an open, pilot, dose-escalation study of glyceryl trinitrate (GTN, Nitroglycerin) administered by paramedics in the field within 2 hours of symptom onset to 45 severely hypertensive stroke patients. The primary objective of the study is to evaluate the feasibility, safety, and physiologic efficacy of field-initiated glyceryl trinitrate in achieving modest reduction of blood pressure. Patients with acute stroke will be identified in the field by paramedics who have received training in basic and advanced cardiac life support, stroke recognition, and specific procedures relevant to the proposed study. Physician-investigators will obtain informed consent for each subject for study entry after cellular phone contact with paramedics. Paramedics will initiate antihypertensive treatment by applying transdermal GTN patch in the first two dose-tiers, and administering a single sublingual GTN metered spray followed by application of the transdermal system in the last dose tier. The sites involved in the study will be emergency medical services rescue ambulances and 8 receiving Stroke Center hospitals in Orange County, California, USA.
The proposed study was set up to evaluate the tolerability and safety of 25% human albumin (HA) therapy in patients with subarachnoid hemorrhage (SAH). It is estimated that 37,500 people in the USA have SAH every year. SAH is associated with a 51% mortality rate and one third of survivors are left functionally dependent. Cerebral vasospasm (CV) has been identified as the most important reason for neurological deterioration. CV may be due to multiple molecular mechanisms. The use of a neuroprotective agent with various actions, likes HA, would be important for prevention of CV and improved clinical outcome in patients with SAH. The proposed open-label, dose-escalation study will have important public health implications by providing necessary information for a definitive phase III clinical trial regarding the efficacy of treatment with HA in patients with SAH. The study was to enroll a maximum of 80 patients with SAH who meet the eligibility criteria. Four dosages of HA (0.625, 1.25, 1.875, and 2.5 g/kg) administered daily for seven days will be evaluated. The lowest dosage was to be evaluated in the first group of 20 subjects. A specific safety threshold was defined based on data from previous studies. The Data and Safety Monitoring Board approved or disapproved advancing to the next higher HA dosage based on the evaluation of the rate of congestive heart failure (CHF). The study assessed three outcomes: safety and tolerability of the HA dosages and the functional outcome. The primary tolerability outcome was defined as the subject's ability to receive the full allocated dose of HA without incurring frank CHF that requires termination of treatment. Secondary safety outcomes were serious adverse events (including neurological and medical complications, and anaphylactic reactions). Neurological complications comprise incidence of CV, rebleeding, hydrocephalus, and seizures after treatment. The three-month functional outcome determined, by Glasgow Outcome Scale, Barthel Index, modified Rankin Scale, NIH Stroke Scale and Stroke Impact Scale was measured to obtain a preliminary estimate of the treatment effect of HA. The timeline of the study is three years.
This is a randomized, double-blind, placebo-controlled, multicenter clinical trial that will be carried out in Mexico. The purpose of this study is to test whether a 3-month treatment with fluoxetine enhances motor recovery in non-depressed patients with acute intracerebral hemorrhage.
The main purpose of this study is to determine whether treatment with deferoxamine mesylate is of sufficient promise to improve outcome before pursuing a larger clinical trial to examine its effectiveness as a treatment for brain hemorrhage.
The objective of this multi-centre, randomized controlled trial is to investigate the outcome after induced hypertension versus no induced hypertension in patients with delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (SAH), and to assess whether induced hypertension results in improved cerebral blood flow (CBF) as measured by means of perfusion-CT.
The postpartum hemorrhage (PPH) is the major complication of the delivery. In clinical practice, if after giving birth, the placenta is not expelled naturally, an active management should be triggered. Escalating therapy after obstetric maneuvers (placenta, uterus, examination of the birth canal), begins with uterotonic treatments for invasive treatments lead to embolization, vessel ligation and hysterectomy. However, the morbidity of these techniques and the desire to preserve fertility required to devise new therapeutic solutions, which have recently led to the development of an innovative medical device intrauterine hemostasis. The postpartum haemorrhage are mainly the result of weak and bleeding from the surface corresponds to the placental insertion, which is no longer localized. With the innovative medical device, our main hypothesis is that the uterine walls will append to the walls of the cup after depressurization of the latter. The actuation of the suction cup will lead to aspiration of all sides of the uterus (it is mostly the anterior and posterior that are important). The suction cup is flexible to adapt to the size of the uterus in order to be placed and removed easily from the uterine cavity.
The purpose of this retrospective study is to test the hypothesis that uncontrolled tachycardia serves as a risk factor for adverse cardiovascular events and poor outcome after Subarachnoid Hemorrhage (SAH).
Intraventricular hemorrhage (IVH) in preterm infants is one of many devastating consequences of prematurity that have both acute and long-term sequelae. Turning a preterm infant's head to one side may increase intracranial pressure and occlude major ipsilateral veins in the neck, which could increase cerebral venous pressure and decrease cerebral venous drainage. Keeping preterm infants' heads in a slightly elevated midline position (side or supine) during the first 168 hours(HOL) has been recommended as one of the 10 potentially better practices to reduce the incidence of IVH in preterm infants. To the best of our knowledge, there has been no systematically collected clinical data quantifying the relationship between IVH and head position in preterm infants. However, the midline head position may challenge the well-known right neonatal head position preference. This preference continues until 3-6 months of age, after which preterm neonates keep their heads mainly in midline. The best head position for preterm neonates is still to be determined. Therefore, the investigators are aiming to conduct a large scale multicenter randomized control trial on order to answer the following research question: Does keeping heads of preterm infants less than 30 weeks of gestation in flat midline (FM) throughout the first 168 HOL reduce the risk of IVH compared to right flat lateral (rFL)? We hypothesized that keeping heads of preterm infants less than 30 weeks of gestation in FM throughout the first 168 HOL would reduce the risk of IVH compared to rFL.
