Abstract
Fever is common in patients with stroke and is associated with worse outcomes. Studies in brain injury informed interventions commonly termed therapeutic temperature management (TTM) to improve the monitoring and management of fever. While the role and benefit of TTM in stroke patients has not been well studied, the nurse and healthcare team must extrapolate existing data to determine how to best monitor and apply TTM after stroke. Nurses should be knowledgeable about interventions to monitor and manage complications of TTM (eg, shivering), the studies underway to quantify the impact of fever treatment and emerging technology expected to improve TTM.

Abstract
Therapeutic hypothermia has shown promise as a means to improving neurological outcomes at several neurological conditions. At the clinical level, it has been shown to improve outcomes in comatose survivors of cardiac arrest and in neonatal hypoxic ischemic encephalopathy, but has yet to be convincingly demonstrated in stroke. While numerous preclinical studies have shown benefit in stroke models, translating this to the clinical level has proven challenging. Major obstacles include cooling patients with typical stroke who are awake and breathing spontaneously but often have significant comorbidities. Solutions around these problems include selective brain cooling and cooling to lesser depths or avoiding hyperthermia. This review will cover the mechanisms of protection by therapeutic hypothermia, as well as recent progress made in selective brain cooling and the neuroprotective effects of only slightly lowering brain temperature. Therapeutic hypothermia for stroke has been shown to be feasible, but has yet to be definitively proven effective. There is clearly much work to be undertaken in this area.

Abstract
Aneurysmal subarachnoid hemorrhage is a neurologic emergency that requires immediate patient stabilization and prompt diagnosis and treatment. Early measures should focus on principles of advanced cardiovascular life support. The aneurysm should be evaluated and treated in a comprehensive stroke center by a multidisciplinary team capable of endovascular and, operative approaches. Once the aneurysm is secured, the patient is best managed by a dedicated neurocritical care service to prevent and manage complications, including a syndrome of delayed neurologic decline. The goal of such specialized care is to prevent secondary injury, reduce length of stay, and improve outcomes for survivors of the disease.

Targeted Temperature Management at 36 °C Shows Therapeutic Effectiveness via Alteration of Microglial Activation and Polarization After Ischemic Stroke. Transl Stroke Res 2021; 13:132-141. [PMID: 33893993 DOI: 10.1007/s12975-021-00910-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2020] [Revised: 02/03/2021] [Accepted: 04/12/2021] [Indexed: 02/02/2023]
Abstract
Ischemic injury leads to cell death and inflammatory responses after stroke. Microglia especially play a crucial role in this brain inflammation. Targeted temperature management (TTM) at 33 °C has shown neuroprotective effects against many acute ischemic injuries. However, it has also shown some adverse effects in preclinical studies. Therefore, we explored the neuroprotective effect of TTM at 36 °C in the ischemic brain. To confirm the neuroprotective effects of hypothermia, mice were subjected to a permanent stroke and then treated with one of the TTM paradigms at 33 and 36 °C. For comparison of TTM at 33 and 36 °C, we examined neuronal cell death and inflammatory response, including activation and polarization of microglia in the ischemic brain. TTM at 33 and 36 °C showed neuroprotective effects in comparison with normal body temperature (NT) at 37.5 °C. Mice under TTM at 33 and 36 °C showed ~ 45-50% fewer TUNEL-positive cells than those under NT. In IVIS spectrum CT, the activation of microglia/macrophage in CX3CR1GFP mice reduced after TTM at 33 and 36 °C in comparison with that after NT on day 7 after ischemic stroke. The number of Tmem119-positive cells under TTM at 33 and 36 °C was ~ 45-50% lower than that in mice under NT. TTM at 33 and 36 °C also increased the ratio of CD206-/CD86-positive cells than the ratio of CD86-/CD206-positive cells by ~ 1.2-fold. Thus, TTM at 33 and 36 °C could equivalently decrease the expression of certain cytokines after ischemic stroke. Our study suggested that TTM at 33 or 36 °C produces equivalent neuroprotective effects by attenuating cell death and by altering microglial activation and polarization. Therefore, TTM at 36 °C can be considered for its safety and effectiveness in ischemic stroke.

Abstract
Background and Purpose: Fever in the acute phase of stroke leads to an unfavorable clinical outcome and increased mortality. However, no specific form of effective fever treatment has been established, so far. We analyzed the effectiveness of our in-house standard operating procedure (SOP) of fever treatment. Methods: This SOP was analyzed for a period of 33 weeks. Patients with cerebral ischemia (ischemic stroke, transient ischemic attack) or cerebral hemorrhage (intracerebral, subarachnoid) and body temperature elevation of ≥ 37.5°C within the first 6 days after admission were eligible for inclusion in the analysis. The results of SOP group, who's data have been collected prospectively were then compared with a historical control group that had been treated conventionally 1 year earlier in the same period. The data of control group have been collected in retrospect. The primary endpoint was the total duration of the fever for the first 6 days after admission to the stroke unit. Results: A total of 130 patients (mean age of 78 ± 12) received 370 antipyretic interventions. Sequential application of paracetamol (n = 245), metamizole (n = 53) and calf compress (n = 15) led to significant reduction in body temperature. In patients who did not respond to these applications, normothermia could be achieved after infusion of the cooled saline solution. Normothermia could be achieved within 120 min in more than 90% of the cases treated by the SOP. The SOP reduced the fever duration in the 6 days significantly, from 12.2 ± 2.7 h [95% confidence interval (CI) for mean] in the control group to 3.9 ± 1.0 h (95% CI) in the SOP group (p < 0.001). The SOP was rated to be reasonable and effective. Conclusion: Our in-house SOP is cost-efficient and effective for fever treatment in stroke patients, that can be implemented by local health care professionals.

Abstract
Ischemic stroke is one of the leading causes for death and disability worldwide. In patients with large space-occupying infarction, the subsequent edema complicated by transtentorial herniation poses a lethal threat. Especially in patients with malignant middle cerebral artery infarction, brain swelling secondary to the vessel occlusion is associated with high mortality. By decompressive craniectomy, a significant proportion of the skull is surgically removed, allowing the ischemic tissue to shift through the surgical defect rather than to the unaffected regions of the brain, thus avoiding secondary damage due to increased intracranial pressure. Several studies have shown that decompressive craniectomy reduces the mortality rate in patients with malignant cerebral artery infarction. However, this is done for the cost of a higher proportion of patients who survive with severe disability. In this review, we will describe the clinical and radiological features of malignant middle cerebral artery infarction and the role of decompressive craniectomy and additional therapies in this condition. We will also discuss large cerebellar stroke and the possibilities of suboccipital craniectomy.

Abstract
Cerebral arterial gas embolism (CAGE) shows various manifestations according to the quantity of gas and the brain areas affected. The symptoms range from minor motor weakness, headache, and confusion to disorientation, convulsions, hemiparesis, unconsciousness, and coma. A 46-year-old man was transferred to our emergency department due to altered sensorium. Immediately after a controlled ascent from 33 m of seawater, he complained of shortness of breath and rigid extremities, lapsing into unconsciousness. He was intubated at another medical center, where a brain computerized axial tomography scan showed no definitive abnormal findings. Pneumothorax and obstructing lesions were apparent in the left thorax of the computed tomography scan. Following closed thoracostomy, we provided hyperbaric oxygen therapy (HBOT) using U.S. Navy Treatment Table (USN TT) 6A. A brain magnetic resonance imaging diffusion image taken after HBOT showed acute infarction in both middle and posterior cerebral arteries. We implemented targeted temperature management (TTM) to prevent worsening of cerebral function in the intensive care unit. After completing TTM, we repeated HBOT using USN TT5 and started rehabilitation therapy. He fully recovered from the neurological deficits. This is the first case of CAGE treated with TTM and consecutive HBOTs suggesting that TTM might facilitate salvage of the penumbra in severe CAGE.

Update on the Treatment of Spontaneous Intraparenchymal Hemorrhage: Medical and Interventional Management. Curr Treat Options Neurol 2018; 20:1.

Abstract
PURPOSE OF REVIEW Spontaneous intraparenchymal hemorrhage (IPH) is a prominent challenge faced globally by neurosurgeons, neurologists, and intensivists. Over the past few decades, basic and clinical research efforts have been undertaken with the goal of delineating biologically and evidence-based practices aimed at decreasing mortality and optimizing the likelihood of meaningful functional outcome for patients afflicted with this devastating condition. Here, the authors review the medical and surgical approaches available for the treatment of spontaneous intraparenchymal hemorrhage, identifying areas of recent progress and ongoing research to delineate the scope and scale of IPH as it is currently understood and treated. RECENT FINDINGS The approaches to IPH have broadly focused on arresting expansion of hemorrhage using a number of approaches. Recent trials have addressed the effectiveness of rapid blood pressure lowering in hypertensive patients with IPH, with rapid lowering demonstrated to be safe and at least partially effective in preventing hematoma expansion. Hemostatic therapy with platelet transfusion in patients on anti-platelet medications has been recently demonstrated to have no benefit and may be harmful. Hemostasis with administration of clotting complexes has not been shown to be effective in reducing hematoma expansion or improving outcomes although correcting these abnormalities as soon as possible remains good practice until further data are available. Stereotactically guided drainage of IPH with intraventricular hemorrhage (IVH) has been shown to be safe and to improve outcomes. Research on new stereotactic surgical methods has begun to show promise. Patients with IPH should have rapid and accurate diagnosis with neuroimaging with computed tomography (CT) and computed tomography angiography (CTA). Early interventions should include control of hypertension to a systolic BP in the range of 140 mmHg for small hemorrhages without intracranial hypertension with beta blockers or calcium channel blockers, correction of any coagulopathy if present, and assessment of the need for surgical intervention. IPH and FUNC (Functional Outcome in Patients with Primary Intracerebral Hemorrhage) scores should be assessed. Patients should be dispositioned to a dedicated neurologic ICU if available. Patients should be monitored for seizures and intracranial pressure issues. Select patients, particularly those with intraventricular extension, may benefit from evacuation of hematoma with a ventriculostomy or stereotactically guided catheter. Once stabilized, patients should be reassessed with CT imaging and receive ongoing management of blood pressure, cerebral edema, ICP issues, and seizures as they arise. The goal of care for most patients is to regain capacity to receive multidisciplinary rehabilitation to optimize functional outcome.

BMC Neurol 2017; 17:205.

Abstract
Background Moderate hypothermia after decompressive surgery might not be beneficial for stroke patients. However, normothermia may prove to be an effective method of enhancing neurological outcomes. The study aims were to evaluate the application of a pre-specified normothermia protocol in stroke patients after decompressive surgery and its impact on temperature load, and to describe the functional outcome of patients at 12 months after treatment. Methods We analysed patients with space-occupying middle cerebral artery (MCA) infarction treated with decompressive surgery and a pre-specified temperature management protocol. Patients treated primarily with device-controlled normothermia or hypothermia were excluded. The individual temperature load above 36.5 °C was calculated for the first 96 h after hemicraniectomy as the Area Under the Curve, using °C x hours. The effect of temperature load on functional outcome at 12 months was analysed by logistic regression. Results We included 40 stroke patients treated with decompressive surgery (mean [SD] age: 58.9 [10.1] years; mean [SD] time to surgery: 30.5 [16.7] hours). Fever (temperature > 37.5 °C) developed in 26 patients during the first 96 h after surgery and mean (SD) temperature load above 36.5 °C in this time period was 62,3 (+/− 47,6) °C*hours. At one year after stroke onset, a moderate to moderately severe disability (modified Rankin Scale score of 3 or 4) was observed in 32% of patients, and a severe disability (score of 5) in 37% of patients, respectively. The lethality in the cohort at 12 months was 32%. The temperature load during the first 96 h was not an independent predictor for 12 month lethality (OR 0.986 [95%-CI:0.967–1.002]; p < 0.12). Conclusions Temperature control in surgically treated patients with space-occupying MCA infarction using a pre-specified protocol excluding temperature management systems resulted in mild hyperthermia between 36.8 °C and 37.2 °C and a low overall temperature load. Future prospective studies on larger cohorts comparing different strategies for normothermia treatment including temperature management devices are needed.
