Burst Motor Cortex Stimulation Evokes Sustained Suppression of Thalamic Stroke Pain: A Narrative Review and Single-Case Overview
AbstractChronic refractory central post-stroke pain (CPSP), one of the most disabling consequences of cerebral stroke, occurs in up to 10% of patients with CPSP. Because a considerable proportion of these patients with chronic pain remain resistant to pharmacological and behavioral therapies, adjunctive invasive and non-invasive brain stimulation therapies are needed. We performed a review of human studies applying burst and conventional motor cortex stimulation (burstMCS and cMCS, respectively) for chronic pain states, on the basis of data sources identified through searches of PubMed, MEDLINE/OVID, and SCOPUS, as well as...

Chronic Use of Angiotensin Converting Enzyme Inhibitors and/or Angiotensin Receptor Blockers is Not Associated With Stroke After Noncardiac Surgery: A Retrospective Cohort Analysis
Conclusion: We did not detect an effect of chronic ACEI/ARB use on postoperative strokes in patients who had non-neurological, noncarotid and noncardiac surgery; however, power was extremely limited.

Post-stroke shoulder pain: Nociceptive or neuropathic?
Acute rehabilitation after stroke can be adversely affected by complications such as pain in the hemiplegic shoulder. The onset of hemiplegic shoulder pain (HSP) can compromise functional gains, and has been shown to contribute to longer term disability . The first systematic study of the incidence of post-stroke shoulder pain (PSSP) found that 40% of patients were affected during the 3–6months following survival of a stroke . In 25% of patients, pain occurred during the first two weeks after stroke . The prognosis at six months, however, appears to be reasonably good, with 80% of patients reporting improvement or comple...

Inability to self-report pain after a stroke: A population-based study
Summary: The inability to self-report pain after a stroke is less common than previously thought, and is associated with both aphasia and level of consciousness.Abstract: The frequency of not being able to self-report pain after a stroke has not been previously assessed in a population-based sample. We studied the epidemiology of this problem using a cohort of patients hospitalized after a stroke in Olmsted County, Minnesota, from June 1, 2008, to June 1, 2012. Overall, 52 of 388 (13.4%) individuals were unable to provide a meaningful response to either a Faces Pain Scale or Numerical Rating Scale on admission. Inability t...

Intraoperative epiaortic scanning for preventing early stroke after off-pump coronary artery bypass
Conclusions EAS has a significant clinical benefit in reducing the incidence of early stroke in cases of partial aortic clamping in OPCAB. Therefore, EAS should be considered in patients who need partial aortic clamping in OPCAB.

Decreased risk of secondary brain herniation with intracranial pressure monitoring in patients with haemorrhagic stroke
In this study, we investigated the clinical value of ICP monitoring in patients with hemorrhagic stroke. Methods: We conducted a randomized, unblinded, controlled trial in which 90 patients with hemorrhagic stroke were randomly assigned to ICP monitoring or a control group. The primary outcome was a composite of incidence rate of hematoma enlargement and secondary brain herniation. The secondary outcome was neurological status assessed using the Glasgow Outcome Scale scores at 6 months post-onset. Characteristics of the patients at baseline and outcome measurements were also compared between the two groups. Results: There ...

Postoperative rescue closure of patent foramen ovale in the clinical setting of acute hypoxemic respiratory failure and stroke following coronary artery bypass surgery.
We describe a case of intraoperative diagnosis and successful deferred percutaneous closure of a patent foramen ovale (PFO) in the clinical setting of acute refractory hypoxemic respiratory failure and new-onset ischemic stroke in an elderly patient after coronary artery bypass graft. Perioperative morbidity (i.e. severe hypoxemia, worsening right ventricular dysfunction, and embolic stroke) that is potentially related to intraoperatively diagnosed PFO during cardiac surgery can complicate management in the Intensive Care Unit and perhaps affect the patient's outcome. Although the PFO closure can be challenging in the clin...

The comparison between stroke volume variation and filling pressure as an estimate of right ventricular preload in patients undergoing renal transplantation
Conclusions This study confirmed the theoretical framework of right ventricular preload and ventricular filling pressure and respiratory variation of stroke volume. The result also suggests that SVV can correctly predict preload status compared to pressure-based indices.

Cerebral protection during neurosurgery and stroke
This article reviews the recent evidence on perioperative neuroprotection in patients undergoing brain surgery and in patients with acute stroke. Recent findings: With varying degrees of success, numerous pharmacological and nonpharmacological therapies have been employed to provide neuroprotection for patients during the perioperative period and after acute ischemic stroke (IAS). Recent studies have failed to demonstrate neuroprotective effects of intraoperative remifentanil or propofol use, although hypertonic saline may provide better brain relaxation than mannitol during elective intracranial surgery for tumor. Magnesi...

Randomized controlled trial of stroke volume optimization during elective major abdominal surgery in patients stratified by aerobic fitness
Conclusions Algorithm-driven stroke volume optimization is of no benefit when superimposed on a liberal baseline fluid regimen in patients having elective major abdominal surgery, when stratified to minimize differences in fitness and surgical approach between groups. Clinical trial registration ISRCTN21597243.

Recognition and Management of Perioperative Stroke in Hospitalized Patients
We sought to characterize stroke management and outcomes in a postoperative population. By using the electronic medical records, we identified 39 patients suffering perioperative stroke after noncardiac and nonneurosurgical procedures for whom documentation of management and outcomes was available. Thirty-three strokes occurred during admission, whereas 6 occurred after discharge and were recognized upon return to the hospital. Perioperative stroke was associated with delayed recognition, infrequent intervention, and significant rates of morbidity and mortality, suggesting the need for improved screening and more rapid tre...

Carotid Artery Disease as a Predictor of In-Hospital Postoperative Stroke After Coronary Artery Bypass Grafting From 1999 to 2011
In this study, the risk factors for stroke after coronary artery bypass grafting (CABG) were examined. In particular, the role of asymptomatic carotid artery stenosis (both unilateral and bilateral) as a predictor of in-hospital postoperative stroke was investigated. Finally, the trends surrounding in-hospital postoperative stroke from 1999 to 2011 also were examined. The purpose of the study was to appropriately identify patients at high risk for stroke after CABG and spark discussion about the perioperative management of such patients.

Perioperative stroke & #8211; Prediction, Prevention, and Protection
Amarja S NagreIndian Journal of Anaesthesia 2018 62(10):738-742 Stroke culminates into 6.2 million deaths annually and is thereby a leading cause of disability and death worldwide. In patients undergoing noncardiac, nonneurological surgery, perioperative stroke can eventuate into a catastropic aftermath with almost eight-fold rise in mortality. In cardiac, neurological, and carotid surgery, stroke rate accounts to be high (2.2%–5.2%) and is a significant instigator of morbidity and mortality as well. These facts kindle interest to review the predictive parameters, preventive measures, an...
