Tracheostomy With Bedside Simultaneous Gastrostomy Vs Usual Care Tracheostomy And Delayed Gastrostomy...

StrokeAcute8 more

There is currently no prospective study analyzing the effect of tracheostomy with bedside simultaneous gastrostomy versus tracheostomy with delayed gastrostomy placement (TSG versus TDG) on the outcomes of neurocritically-ill patients. The investigators will study TSG via concomitant PDT and PUG procedures, while TDG will occur per usual care. This study is a prospective randomized open-label blinded endpoint study to assess the effect of tracheostomy with bedside simultaneous gastrostomy (TSG) versus the usual care of tracheostomy with delayed gastrostomy (TDG) placement on outcomes of neurocritically-ill patients.

Intravenous Levetiracetam as First-line Anticonvulsive Treatment in Patients With Non-convulsive...

Status EpilepticusNon-Convulsive

Status epilepticus (SE) represents the most common life-threatening neurological emergency requiring treatment on an intensive care unit. The incidence in Western European countries is about 12-18/100'000. Immediate and effective treatment of SE is obviously essential because of the deleterious effects of continuous seizures on the brain and the whole organism. Guidelines emphasize the use of benzodiazepines (BZD) as first-line anticonvulsive drugs. Alternatively, i/v Phenytoin (PHE), fosphenytoin (FOS), and valproate (VPA) were also tested as first-line anticonvulsants in SE. Direct comparison of PHE with lorazepam (LZP) showed significant superiority of LZP (evidence class I). Other trials i/v PHE or -VPA are of evidence class III or IV. BZD, VPA, and PHE have clinical and pharmacological disadvantages. BZD may cause respiratory depression or sedation and may be not suitable for patients with COPD or ambiguous in patients with BZD addiction. Some compounds also may induce tachyphylaxis or accumulate under concomitant renal failure. PHE has saturable metabolism subject to Michaelis-Menten kinetics increasing the risk of overdosing in an acute setting causing liver damage, serious cardiac arrhythmias, hypotension, cerebellar degeneration, peripheral neuropathy and local/systemic skin reactions. Although of unequivocal efficacy, PHE should no longer be used for long-term because of its adverse effects after chronic administration (irreversible cerebellar degeneration causing debilitating ataxia, painful polyneuropathy, and osteopenia increasing the risk of fractures). Metabolism by and self-induction of the hepatic CYP450 system make PHE prone to interactions with several other drugs, notably other antiepileptics. VPA may cause liver failure, hemorrhagic complications, pancreatitis, and hyperammonemic encephalopathy. To summarize, these three first-line agents for the treatment of SE may cause serious side effects in several patients with SE. Levetiracetam (LEV) is broad-spectrum antiepileptic drug. It binds to the presynaptic vesicular protein 2A abundantly present in different regions of the brain; LEV presynaptically modulates transmitter release, but the exact mechanism(s) remain unclear. Data also revealed that LEV stabilizes GABAA receptors upon repetitive activation what is important in treatment of SE because GABAA receptors undergo significant changes of subunit conformation within minutes after sustained activation like during SE. These changes render GABAA receptors the less anticonvulsive, the longer SE lasts. Levetiracetam has a favorable pharmacological profile with large safety margins. Its partly extrahepatic hydrolyzation bypasses the CYP450 system; renal excretion is 60-70% unchanged, and 23-27% metabolized. Dosage needs adjustment when renal function is impaired. LEV lacks interactions with any drugs yet. Drowsiness is the most common side-effect while respiration, liver and kidney function, and the blood system are not affected. LEV shows an important clinical effect even after the first dose and maximal efficacy within the first week of drug-intake. The favorable clinico-pharmacological profile predilects LEV for the first-line treatment of SE, especially in patients with multi-organ failure, sepsis, coma etc.. About 10 % of comatous patients may be in non-convulsive SE (NCSE) on ICU's. These patients are under polymedication whereby interactions of the anticonvulsants approved yet for the treatment of NCSE with their other drugs may have fatal effects. Conversely, non-interacting anticonvulsants would represent an advantage for the treatment of NCSE for these patients. Recently, the i/v formulation of LEV was approved by the FDA for the use in patients, but not specifically for the treatment of SE. Data about the single-dose bioavailability of i/v-LEV in comparison to oral tablets as well as multiple-dose pharmacokinetics and tolerability in healthy subjects were recently published. In addition, the administration of i/v-LEV dosages ranging from 2000-4000 mg within 15 minutes and of dosages ranging from 1500-2500 mg within 5 minutes was safe and well tolerated, and led to efficacious drug levels in a randomized, single-blind, placebo-controlled safety and pharmacokinetic study in healthy volunteers. Slight somnolence is expected to be the only adverse effect of i/v LEV, sharply contrasting with the sedation up to coma after i/v benzodiazepines. Thus, even severely ill patients will be accessible to neurological tests under LEV which is a big advantage in this clinical difficult setting of NCSE. I-v LEV is considered an ideal candidate for the first-line use (before benzodiazepines) in patients with NCSE, especially in those with important comorbidity and concomitant polymedication. Thus, we would like to test the feasibility, safety, and efficacy of i/v-LEV as first-line medication in a open-label, single-center, prospective pilot study as outlined below.

EEG Monitoring for Refractory Status Epilepticus

Status Epilepticus

This is a prospective randomized study to investigate the yield of continuous electroencephalogram (cEEG), as a diagnostic tool in intensive care unit (ICU), for patients with refractory status epilepticus (RSE) and the contribution of this test to the patient final outcome, compared with standard medical care. Specifically, the hypothesis is that the use of cEEG for patients with RSE will significantly reduce the length of in-hospital stay, mortality, and subsequent complications (such as infections or pressure ulcers). It is also predicted that quality of life will be higher following cEEG at 0, 3, 6 and 12 months after discharge. As there are currently no data available from previous studies assessing the impact of cEEG on markers of the final clinical outcome in patients with RSE, this study is going to start as a feasibility study, aiming to obtain initial data for the primary outcome measure, in order to perform a sample size calculation for a larger future trial. The pilot study will also assess the integrity of the study protocol, specifically the recruitment process and the consent procedure, and also determine the necessary costs for running a cEEG service in ICU for patients with RSE

Respiratory FailureStatus Epilepticus2 more

This study evaluates the impact of video communication via telemedicine on the quality of emergency care provided to children by paramedic teams supported by a remote physician in a simulated out-of-hospital setting. Half of the paramedic teams will use a video telemedicine platform for communication with a physician, while the other half will use an audio-only platform.

Phenobarbital Versus Valproate for Generalized Convulsive Status Epilepticus

Generalized Convulsive Status Epilepticus

Although generalized convulsive status epilepticus (GCSE) is a life-threatening emergency, evidence-based data to guide initial drug treatment choices are lacking in the Chinese population. The investigators conduct this prospective randomized controlled trial to evaluate the relative efficacy and safety of intravenous (IV) phenobarbital (PB) and valproate (VPA) in patients with GCSE.
