“…Other neurodiagnostic modalities known to improve the care of stroke patients are MRI, and CT angiography. MRI is an advancement on CT or CT angiography [23] though none of our patients did MRI [24] [25] [26] [27].…”

Background: Stroke patients form an integral part of patients admitted into the intensive care unit (ICU); and may need airway maintenance, supplemental oxygen and even endotracheal intubation for mechanical ventilation. Method: In this retrospective study, the medical records and radiological investigations of the patients were assessed. Also, their socio-demographics, and clinical diagnosis and background co-morbidities were noted. The radiological diagnosis post CT was used to determine the type of stroke for those compliant; while clinical assessment alone was used to determine the diagnosis in those who did not do CT. They were also classified into 2 groups: those requiring mechanical ventilation (for ICU care) and those without the need for mechanical ventilation (for high dependency Unit (HDU) care). The eventual clinical outcome was noted. Result: A total of eighty-eight cases, 67% (n = 59) were males and 33% (n = 29) females. 89.8% (n = 79) had hypertension, 3.4% (n = 3) had diabetes while 6.8% (n = 6) had both hypertension and diabetes. Of the hypertensives, 36.7% (n = 29) had hemorrhagic stroke and 66.3% (n = 50) had ischaemic stroke. 53.3% (n = 46) patients had High dependency Unit (HDU care while 47.7% (n = 42) were mechanically ventilated. Of the number in HDU, 51.5% (n = 17) were haemorrhagic, while 52.7% (n = 29) were ischaemic. Clinical diagnosis of ischemic stroke was done in 55 (62.5%) and hemorrhagic stroke in 37.5% (n = 33). Of the lot, only 19.3% (n = 17) of them did CT and 80.7% (n = 71) did not have CT done. None did MRI. Late presentation (beyond 24 hrs) was a common feature for most of the patients, for whom immediate cardio-respiratory support became necessary. Overall mortality rate was 62.5% (n = 55). 39.1% (n = 18

“…In everyday clinical life, the choice of imaging to be performed depends on purpose and availability. 8 , 9 In order to stratify and correctly prioritize patients most likely to have a stroke several clinical screening tools have been developed. Their diagnostic sensitivity and specificity ranges vary widely in different studies (sensitivity 73.9%–91%, specificity 64%–88.7%).…”

Purpose To evaluate if the Strokefinder MD 100 by Medfield Diagnostics AB can be used as a point of care device in overcrowded Emergency Departments (ED). Patients and Methods We used the strokefinder MD 100 by Medfield Diagnostics AB in two Greek National Health System (NHS) Hospitals Emergency Departments. Our research protocol was approved by local scientific and ethics committees. We prospectively enrolled 71 adult patients from two NHS emergency departments in whom stroke was included as a differential diagnosis after triage. The feasibility of using the Strokefinder MD 100 by Medfield Diagnostics AB in various emergency department settings was evaluated through a structured questionnaire. Results The strokefinder MD 100 was used on 71 patients in various settings in the Emergency Department. In every case, the test was completed at the patient bedside without interfering with other ongoing and diagnostic and resuscitation procedures. There was no additional delay to patient care caused by performing the test when compared with current local Emergency Department practice and protocol. In almost 90% of the cases, a clear result was produced by the device. Conclusion The Strokefinder MD 100 can be safely used as a point of care device by all trained healthcare professionals, in the most overcrowded emergency department, in various ED locations. MeSH terms Point of Care Systems, Cerebrovascular Stroke, Proof of Concept Study.

“…Non-invasive techniques, such as CT, fMRI, MEG, and PET, can achieve high temporal and spatial resolution. However, these tools are bulky and not easy to access, which is not appropriate for real-time monitoring [4]. Thus, lightweight, compact systems like EEG and fNIRS attract attention [5].…”

Infrared Spectroscopy - Perspectives and Applications

View full text Add to dashboard Cite

Functional near-infrared spectroscopy (fNIRS) is an emerging wearable neuroimaging technique based on monitoring the hemodynamics of brain activity. First, the operation principle of fNIRS is described. This includes introducing the absorption spectra of the targeted molecule: the oxygenated and deoxygenated hemoglobin. Then, the optical path formed by emitters and detectors and the concentration of the molecules is determined using Beer-Lambert law. In the second part, the advantages of applying fNIRS are compared with other neuroimaging techniques, such as computed tomography and magnetic resonance imaging. The compared parameters include time and spatial resolution, immobility, etc. Next, the evolution of the fNIRS devices is shown. It includes the commercially available systems and the others under construction in academia. In the last section, the applications of fNIRS to avoid stroke are presented. The challenges of achieving good signal quality and high user comfort monitoring on stroke patients are discussed. Due to the wearable, user-friendly, and accessibility characteristics of fNIRS, it has the potential to be a complementary technique for real-time bedside monitoring of stroke patients. A stroke risk prediction system can be implemented to avoid stroke by combining the recorded fNIRS signals, routinely monitored physiological parameters, electronic health records, and machine learning models.
