In-hospital neuro alerts are typically activated when a patient's neurological status changes from their baseline. Neuro alerts are usually called by nurses, who are often the first to recognize acute neurological changes and stroke-like symptoms. However, physicians, patient family members, and staff can also report acute in-hospital strokes. When a neuro alert is called, it prompts a rapid response from the medical team, including the CT scan technician, to provide timely neurological intervention and improve patient outcomes. Additionally, Neuro Alert is also the name of a leading provider of Intraoperative Neurophysiological Monitoring (IONM), a technique used to improve safety and patient outcomes during surgical procedures.

In-hospital stroke alerts are activated when acute neurological changes are observed
In-hospital stroke alerts are activated when a patient's neurological status changes from their baseline. This can include factors such as balance, as well as laboratory data such as coagulation factors, blood glucose, and complete blood counts. The rapid intervention is crucial in minimising neurological deficits and improving patient outcomes.
When a stroke alert is called, it is essential to get the patient the necessary resources for timely stroke intervention. This includes alerting the CT scan technician to prepare the scanner for the patient's arrival. The patient's safety is paramount, and it is important to monitor them for any worsening or improvement of stroke symptoms.
The use of alteplase, a medication for stroke intervention, relies on several factors, including the time since the patient was last seen normal (LSN), their medical history, blood pressure, and lab results. Alteplase is typically administered within a specific time frame since LSN, which can vary depending on hospital protocols.
In-hospital strokes are often treated more slowly than out-of-hospital strokes. This is partly due to the fact that neurology teams may not evaluate hospitalized patients immediately, leading to a delay in diagnosis and treatment. However, overtriaging false alerts can also overwhelm resources and pose challenges to stroke response teams, so it is important to carefully assess the patient's condition before activating a stroke alert.

Stroke alerts facilitate rapid intervention to minimise neurological deficits
A stroke alert is a way to quickly get a patient the resources they need for timely stroke intervention. When a stroke alert is called, the CT scan technician is alerted to clear the scanner and prepare for the patient's arrival. Stroke alerts are typically called when a patient's neurological status acutely changes from their baseline. Nurses are often the first to recognise acute neurological changes and stroke-like symptoms, and they are usually the first to call a stroke alert.
In-hospital strokes are often treated much more slowly than out-of-hospital strokes. This is partly because a neurology team does not evaluate most hospitalised patients for a mean of 14.5 hours from symptom onset when not admitted on a neurology service. However, rapid intervention is key to keeping neurological deficits to a minimum and improving patient outcomes. The alteplase, a medication used to treat strokes, is time-sensitive and must be administered within 3 to 9 hours of the patient being "last seen normal" (LSN).
To ensure rapid intervention, hospitals have implemented standardised stroke assessments, such as the NIHSS (National Institute of Health Stroke Scale). This assessment is conducted regularly during the first 24 hours after a stroke alert, which means that patients receive very little sleep during this period. Despite the challenges of evaluating patients who have had a stroke, nurses and physicians must be able to recognise the signs and act quickly to minimise neurological deficits.
Additionally, Intraoperative Neurophysiological Monitoring (IONM) is a technique used to improve patient safety and outcomes during surgical procedures. IONM is considered the gold standard for surgeries that may place the central or peripheral nervous systems at risk. Neuro Alert is a leading provider of IONM, utilising technology, collaboration, and clinical expertise to ensure safe and successful surgeries.

Nurses are often the first to recognise neurological changes and are quicker to call alerts
In a hospital setting, nurses are often the first to recognise neurological changes in patients and are quicker to call alerts compared to physicians. This is likely due to the continuous nature of nursing examinations and the proximity of nurses to their patients. According to a study, nurses called the stroke team a median of almost three hours earlier than physicians.
In-hospital stroke alerts are typically activated when a patient's neurological status changes acutely from their baseline. As nurses are often the first to identify acute neurological changes and stroke-like symptoms, their timely recognition and response are crucial in initiating prompt medical intervention. Rapid intervention is essential in minimising neurological deficits and improving patient outcomes.
Nurses play a vital role in monitoring and evaluating patients' neurological status. They are often well-positioned to detect subtle changes or deviations from a patient's normal state. This early detection enables nurses to promptly activate the necessary medical responses, such as calling a stroke alert.
When a stroke alert is called, it triggers a rapid response from the medical team, including the CT scan technician, who clears the scanner and prepares for the patient's arrival. This immediate response ensures that the patient receives the necessary resources and interventions to manage their neurological condition effectively.
While nurses are often the first to recognise neurological changes, it is important to acknowledge that physicians, patient family members, and staff can also report acute in-hospital strokes. Additionally, the continuous support and collaboration of the medical team are crucial in providing optimal patient care.
Overall, the early recognition and response to neurological changes by nurses play a vital role in ensuring timely medical intervention and improving patient outcomes. Their dedication and proximity to patients contribute to quicker alert calls, ultimately enhancing the quality of care provided in hospital settings.

Intraoperative Neurophysiological Monitoring (IONM) improves patient safety and outcomes
Intraoperative Neurophysiological Monitoring (IONM) is a group of procedures used during surgery to monitor neural pathways and prevent damage to the nervous system. It is used during high-risk surgeries, such as neurosurgical, orthopedic, peripheral nerve, and vascular procedures. IONM helps in assessing the integrity of neural structures and consciousness during these complex operations. The use of IONM has revolutionized neurosurgery by enhancing safety and precision, reducing the risk of complications, and improving patient outcomes.
IONM involves the continuous, real-time assessment of neurophysiological signals, aiding surgeons in timely interventions to protect neural structures. It includes techniques to identify impending damage to the nervous system and methods to map the structures of the nervous system. IONM can be applied to various neurosurgical settings, including intracranial tumor resection, neurovascular surgery, epilepsy surgery, spinal surgery, and peripheral nerve surgery.
One of the significant benefits of IONM is the early recognition and management of any signal changes during the procedure. For example, in spinal surgery, IONM techniques such as motor-evoked potentials (MEPs), somatosensory-evoked potentials (SSEPs), and electromyography (EMG) are employed. These techniques help predict favorable surgical outcomes by allowing surgeons to promptly address any signal alterations.
The overall risk associated with IONM is considered low. However, electrical safety is of utmost importance to prevent complications such as local skin burns. Additionally, patients under anesthesia cannot express discomfort or pain, so it is vital to ensure that IONM equipment is thoroughly checked before the operation. IONM has become an essential part of standard medical practices, and its benefits are leading to its expanded use in various surgical procedures.
In summary, Intraoperative Neurophysiological Monitoring (IONM) is a crucial advancement in medicine, particularly in neurosurgery. It improves patient safety and outcomes by providing real-time monitoring of neural pathways and facilitating early interventions to prevent neurological injuries. With its ability to enhance precision, reduce complications, and preserve nervous system functionality, IONM has become an indispensable tool in high-risk surgical procedures.

Neurological intervention is required to treat hemorrhagic strokes
A stroke alert is a way to quickly get a patient the resources they need for timely stroke intervention. When a stroke alert is called, the CT scan technician is alerted to clear the scanner and prepare for the patient's arrival. A stroke alert should be called anytime stroke symptoms are suspected, no matter how minor. Rapid intervention is key to minimising neurological deficits and improving patient outcomes.
Hemorrhagic strokes are particularly dangerous because they cause severe symptoms that deteriorate quickly. They occur when a blood vessel in the brain breaks and bleeds, leading to potentially fatal consequences. They are associated with severe morbidity and high mortality. The progression of a hemorrhagic stroke is associated with worsening outcomes, hence the need for rapid intervention.
The two main treatments for hemorrhagic strokes are medications and surgery. Clotting support medications such as vitamin K therapy or prothrombin complex concentrate can help increase the body's ability to stop the bleeding in the brain. Blood pressure management is also crucial, as maintaining optimal blood pressure can slow the brain bleed and help the blood clot safely, sealing the damaged blood vessel. Intravenous (IV) blood pressure medication can be used to keep blood pressure in a safe range.
In some cases, surgical evacuation of the hematoma may be required. The role of surgical treatment for hemorrhagic strokes is controversial, with conflicting outcomes in published studies. However, evidence suggests that a subset of patients with lobar hematoma but no intraventricular hemorrhage may benefit from surgical intervention. Additionally, patients with cerebellar hemorrhage and a hematoma greater than 3 cm in diameter have shown improved outcomes with surgery.
Neurological intervention is, therefore, crucial in treating hemorrhagic strokes. This includes the administration of medications to support clotting and manage blood pressure, as well as potential surgical procedures. The involvement of neurology teams and neurosurgeons is essential to assess the need for invasive intracranial pressure monitoring and emergent cerebral angiography.
