Filter by:Postoperative delirium may result in many adverse complications. At present little is known about postoperative delirium in patients after crniotomy because they may manifest similar symptoms to definitely delirium for some structural brain disease. Objective of this study is to find out incidence and risk factors of postoperative delirium in patients after elective craniotomy and also the relationship of postoperative delirium with clinical outcome.
Recent changes in medical training environments and restrictive work-hour regulations have greatly impacted trainees, limiting the number of opportunities to gain proficiency in procedural skills. Reports suggest that medical residents lack confidence in their ability to perform certain medical procedures, and program directors often do not believe their residents can operate independently in major procedures. Simulator based task training (SBTT) has provided a safe and ethically appropriate method of skill acquisition but training opportunities remain limited. Methods to enhance motor learning during these training opportunities have not been described. Transcranial direct-current stimulation (tDCS) is an emerging form of non-invasive brain stimulation that has been shown to improve motor learning. tDCS has been shown to enhance increasingly complex skill acquisition. The investigators propose to examine if tDCS can improve the acquisition and retention of neurosurgical skill. The investigators propose a double blind, sham-controlled randomized trial applying tDCS during evidence-based SBTT of medical students, to determine if brain stimulation can enhance training skill acquisition and retention. Even a modest enhancement carries the potential to transform medicosurgical skills training.
Emergence agitation is a frequent complication that can have serious consequences during recovery from general anesthesia. However, agitation has been poorly investigated in patients after craniotomy. In this prospective multicenter cohort study, adult patients will be enrolled after craniotomy and emergence agitation will be evaluated. The incidence, risk factors and outcome will be investigated.
Recently intraoperative motor evoked potential monitoring (MEP) is widely used to reduce neural damage during neurosurgery. As neuromuscular blockade(NMB) during MEP monitoring decreases the amplitude of MEP, partial NMB is usually maintained during general anesthesia. Continuous infusion of NMB agent is preferred than bolus infusion during MEP monitoring. There are a lot of NMB agents in clinical use. But there have been no reports about the effect of changing NMB agent on efficacy of MEP monitoring. Therefore, the investigators performed a randomized controlled trial to evaluate the effect of changing NMB agent on the variability of MEP amplitude during neurosurgery.
The purpose of this study is to evaluate whether a correlation exists between the partial pressure of carbon dioxide existing within arterial blood and the gradient between inhaled and exhaled fractions of oxygen.
Spinal surgery may be associated with substantial blood loss which often requires erythrocyte transfusion. Transfusion of red blood cells (RBC) is not free of adverse events and has been associated with increased risks of infection, and globally higher morbidity and mortality. Different techniques have been used to reduce perioperative blood losses and related transfusions. Tranexamic acid has been used successfully in cardiac and hepatic surgery. However, only a few studies have reported on the use of antifibrinolytic drugs in spinal surgery. This study was designed to assess the efficacy and safety of tranexamic acid in spinal surgery for the reduction of RBC transfusion. Hypothesis: the infusion of tranexamic acid during spinal surgery will reduce the risk of receiving a RBC transfusion and, in those patients transfused, reduce the number of blood products administered.
Meningitis is a rare complication following neurosurgical procedures and is associated with high morbidity and mortality. The aim of this study is to describe the clinical characteristics and microbiological characteristics in patients who develope meningitis following neurosurgical operations, and investigate the useful tips for the differential diagnosis of postneurosurgical meningitis.
Three different antibiotics are used to prevent infection in case of neurosurgery - this study examines to which extent the antibiotics penetrate from the blood to the cerebrospinal fluid (surrounding the brain).
This protocol, NeuroMorfeo, aims to assess equivalence between volatile and intravenous anesthetics for neurosurgical procedures.
Surgery initiates a complex cascade of events involving the release of chemical compounds from nerve endings and damaged tissue which leads to an inflammatory and pain response. The purpose of this investigation is to measure various chemical mediators in the blood and cerebrospinal fluid, and to test the hypothesis that they will be decreased in patients treated with a COX-2 inhibitor.
