Perioperative Neurological Evaluation and Management to Lower the Risk of Acute Stroke in Patients Undergoing Noncardiac, Nonneurological Surgery: A Scientific Statement From the American Heart Association/American Stroke Association.

Perioperative stroke is a potentially devastating complication in patients undergoing noncardiac, nonneurological surgery. This scientific statement summarizes established risk factors for perioperative stroke, preoperative and intraoperative strategies to mitigate the risk of stroke, suggestions for postoperative assessments, and treatment approaches for minimizing permanent neurological dysfunction in patients who experience a perioperative stroke. The first section focuses on preoperative optimization, including the role of preoperative carotid revascularization in patients with high-grade carotid stenosis and delaying surgery in patients with recent strokes. The second section reviews intraoperative strategies to reduce the risk of stroke, focusing on blood pressure control, perioperative goal-directed therapy, blood transfusion, and anesthetic technique. Finally, this statement presents strategies for the evaluation and treatment of patients with suspected postoperative strokes and, in particular, highlights the value of rapid recognition of strokes and the early use of intravenous thrombolysis and mechanical embolectomy in appropriate patients.

Nurse's Role in Perioperative Neurological Evaluation and Management to Lower the Risk of Acute Stroke in Patients Undergoing Noncardiac, Nonneurological Surgery.

Perioperative nurses have the opportunity to play a key role in prevention and recognition of stroke in patients undergoing noncardiac, nonneurological surgery and may impact this potentially devastating complication. Effective nursing care of the older adult requires a specialized knowledge base. Scientific Statements are a cornerstone of the knowledge base that informs this care. This article summarizes the recently released American Heart Association/American Stroke Association Scientific Statement entitled: Perioperative Neurological Evaluation and Management to Lower the Risk of Acute Stroke in Patients Undergoing Noncardiac, Nonneurological Surgery and discusses the nurse's role in the care of this vulnerable patient population.

Care of the Patient With Acute Ischemic Stroke (Posthyperacute and Prehospital Discharge): Update to 2009 Comprehensive Nursing Care Scientific Statement: A Scientific Statement From the American Heart Association.

In 2009, the American Heart Association/American Stroke Association published a comprehensive scientific statement detailing the nursing care of the patient with an acute ischemic stroke through all phases of hospitalization. The purpose of this statement is to provide an update to the 2009 document by summarizing and incorporating current best practice evidence relevant to the provision of nursing and interprofessional care to patients with ischemic stroke and their families during the acute (posthyperacute phase) inpatient admission phase of recovery. Many of the nursing care elements are informed by nurse-led research to embed best practices in the provision and standard of care for patients with stroke. The writing group comprised members of the Stroke Nursing Committee of the Council on Cardiovascular and Stroke Nursing and the Stroke Council. A literature review was undertaken to examine the best practices in the care of the patient with acute ischemic stroke. The drafts were circulated and reviewed by all committee members. This statement provides a summary of best practices based on available evidence to guide nurses caring for adult patients with acute ischemic stroke in the hospital posthyperacute/intensive care unit. In many instances, however, knowledge gaps exist, demonstrating the need for continued nurse-led research on care of the patient with acute ischemic stroke.

Value Utilization of Emergency Medical Services Air Transport in Acute Ischemic Stroke.

BACKGROUND: Determining whether a patient has a time-critical medical condition requiring helicopter Emergency Medical Services (HEMS) transportation is a challenge with acute ischemic stroke (AIS). Although HEMS is largely accepted as improving outcomes in time-sensitive conditions, overtriage of patients ineligible for acute stroke therapies places patients and providers at unnecessary risk and wastes limited health care resources. OBJECTIVE: We sought to identify how accurate our triage system was at identifying high-yield EMS transfers. A better triage system would decrease the volume of low flight value HEMS transfers. METHODS: We conducted a retrospective study during a 1-year period. Low flight value was defined by acute therapy eligibility and presenting medical status. RESULTS: Of 141 AIS patients transferred by HEMS, 23 (16%) were deemed of low flight value; 14 (61%) were outside the acute treatment time window for either intravenous tissue plasminogen activator or endovascular therapy (EVT); 5 patients (22%) were ineligible for EVT (National Institute of Health Stroke Scale < 6); 2 patients (9%) were ineligible for EVT (Modified Rankin Scale ≥ 3); and 2 patients (9%) were flown despite negative angiographic studies performed at transferring institution. Thirteen (57%) of the patients were interfacility transfers as opposed to direct HEMS transport from the field. CONCLUSIONS: HEMS transport for AIS patients plays a crucial role in delivering the best evidence-based care. However, a significant percent of patients did not meet criteria for its optimal utilization, most commonly due to expired treatment windows. Furthermore, low flight value transfers were initiated in spite of physician evaluation > 50% of the time. These results represent a unique opportunity to coordinate education and build effective triage paradigms across a system of stroke care.

Preoperative diabetes management protocol for adult outpatients.

The lack of evidence-based guidelines or nationally recognized protocols for the preoperative management of adult diabetics in the outpatient setting poses a challenge for the perianesthesia practitioner. The West Virginia University Hospital Perioperative Research Committee sought to develop an institutional protocol for management of this population. A retrospective chart review of diabetic outpatients who arrived the morning of surgery with elevated glucose levels was performed. The purpose of the chart review was to delineate indicators measured in the preoperative visit that could be predictive of patients arriving the morning of surgery with an elevated glucose level. Self-reported home fingerstick glucose values >200mg/dL were a statistically significant (p = .007) indicator of elevated arrival glucose in the preoperative holding area. Results of the chart review and best clinical evidence, as well as expert opinion, were used to develop an Adult Preoperative Diabetes Protocol and an accompanying Patient Instruction Tool.
