This document provides guidance on managing acute stroke in the emergency department. It notes that stroke is a leading cause of death worldwide and causes disability and impacts daily life. There are two main types of stroke: ischemic (70-85% of cases) and hemorrhagic (15-30% of cases). It then discusses signs and symptoms of stroke, definitions, epidemiology, diagnosis through history, neurological exam, imaging, and lab tests. Management principles focus on stabilizing vital functions, restoring cerebral blood flow, preventing complications and progression, controlling risk factors, and rehabilitation. Timely treatment is important to minimize neurological deficits.
A cerebrovascular accident, or stroke, is caused by a lack of oxygenated blood flow to the brain. It can be ischemic, due to a blockage, or hemorrhagic, due to a ruptured blood vessel. Symptoms depend on the affected brain area and can include weakness, sensory changes, speech problems, and visual issues. Stroke severity is classified as mild, moderate, or severe based on symptoms and exam findings. Risk factors include hypertension, atrial fibrillation, diabetes, and lifestyle factors like smoking and diet. Prevention focuses on controlling modifiable risks while treatment involves supportive care, thrombolysis if administered early, and long-term secondary prevention with antiplatelets or anticoagul
Emergency treatment of stroke involves several steps:
1. Rapid diagnosis through imaging such as CT or MRI to determine if the stroke is ischemic or hemorrhagic.
2. For ischemic strokes within 3 hours, treatment with rTPA (recombinant tissue plasminogen activator) can dissolve clots and reduce long-term disability if eligibility criteria are met.
3. Intensive monitoring is required after rTPA to control blood pressure and watch for bleeding complications.
4. Surgery may be considered for large hemorrhagic strokes or subarachnoid hemorrhage from aneurysms to relieve pressure on the brain.
Guidelines for management of acute strokesankalpgmc8
This document provides an overview of stroke types, pathophysiology, investigations, and management guidelines. It discusses the three main types of stroke: ischemic, intracerebral hemorrhage, and subarachnoid hemorrhage. For ischemic stroke, it describes the ischemic core and penumbra. It outlines the emergency evaluation of acute ischemic stroke including vital signs, blood tests, imaging, and scales like the NIH Stroke Scale. Management strategies discussed include thrombolysis, antiplatelet/anticoagulation drugs, neuroprotective agents, and surgical interventions. Complications like cerebral edema and their management are also summarized.
This document discusses endovascular treatment for acute ischemic stroke. It describes the goals of endovascular treatment as expanding the treatment window, including patients resistant to IV treatment or who have exclusion criteria, and increasing recanalization rates. Various endovascular treatments are discussed such as thrombolytic drugs, mechanical thrombectomy devices, and angioplasty. Complications of treatment like hemorrhagic transformation are also reviewed. Clinical trials demonstrating the safety and efficacy of endovascular therapies like the MERCI Retriever and Solitaire device are summarized.
1. An ischemic stroke occurs when a blood clot or fat deposit blocks an artery in the brain, cutting off blood flow and oxygen to brain cells.
2. There are two main types - arterial thrombosis where a clot forms in the brain artery, and cerebral embolism where a clot forms elsewhere and travels to the brain.
3. Risk factors include age, gender, medical conditions like high blood pressure, smoking, high cholesterol, prior transient ischemic attacks, and family history.

5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.

• Penyebab kecacatan dan berdampak besar pada aktivitas harian, sosial dan
ekonomi.
• Jenis stroke:
1. Perdarahan : insiden 15-30 % (Intrakranial dan subarakhnoid)
2. Iskemik : insiden 70-85 %
APA ITU
STROKE?
Stroke merupakan “serangan otak”. Dapat terjadi pada siapa saja tetapi rata-rata yang terserang berusia 70 tahun. Ada
dua jenis stroke yang dikenal yaitu stroke iskemik dan stroke hemoragik/perdarahan.
Stroke iskemik terjadi ketika aliran darah ke salah satu
area otak terhenti. Ketika ini terjadi, sel otak kekurangan
oksigen dan mulai rusak lalu mati. Ketika sel otak mati
saat stroke, kemampuan otak pada area tersebut seperti
memori dan kontrol otot akan menghilang.
STROKE ISKEMIK STROKE HEMORAGIK
Stroke hemoragik terjadi hanya sekitar 15% dari kasus
dan terjadi saat pecahnya pembuluh darah di otak,
menyebabkan kebocoran darah ke dalam otak. Otak
sendiri berada di dalam rongga tengkorak, kebocoran
darah tadi menyebabkan penekanan pada jaringan otak

ATACH-2, whereas a range of intravenous and oral
BP-lowering agents were used in INTERACT2. Any
antihypertensive drug with rapid onset and short
duration of action to facilitate easy titration and
sustained BP control to minimize SBP variability
seems appropriate, although venous vasodilators
may be harmful because of unopposed venodila-
tion and its effect on hemostasis and ICP.157

• The potential synergistic benefits of a bundle of
care, including BP lowering and reversal of antico-
agulation, should be studied, as well as specific care
pathways (eg, keeping reversal agents on the ward,
not requiring consultation with hematology, train-
ing of nurses). Such pathways may reduce time to
reversal of anticoagulants and improve outcome.

of the hematoma who were also receiving aspirin
therapy. Results showed that transfusion of 1 U
of previously frozen apheresis platelets before
surgery, with or without an additional platelet
unit 24 hours later, reduced postoperative rate
and volume of hemorrhage.206
Platelet transfu-
sion also was associated with higher activities
of daily living (ADL) score and lower 6-month
mortality. All patients screened were investigated
with a platelet aggregation test to exclude those
with aspirin resistance. The excluded patients did
not receive platelet transfusions; however, their
outcomes were similar to those of patients with
sensitivity to aspirin and treated with platelet
transfusions. Among the methodological limita-
tions of this trial, SAEs were not reported in this
population, cases with incomplete hemostasis
during operation were excluded, nonuniform sur-
gical procedures were performed, and the meth-
odology of ICH volume determination was below
the current standard. Platelet aggregation testing
is rarely available on an emergency basis in clini-
cal practice.
