Carbon Dioxide, Blood Pressure, and Perioperative Stroke: A Retrospective Case-Control Study.

Background: The relationship between intraoperative physiology and postoperative stroke is incompletely understood. Preliminary data suggest that either hypo- or hypercapnia coupled with reduced cerebrovascular inflow (e.g.

Stroke in Surgical Patients.

Stroke is associated with substantial morbidity and mortality. The aim of this review is to provide an evidence-based synthesis of the literature related to perioperative stroke, including its etiology, common risk factors, and potential risk reduction strategies. In addition, the authors will discuss screening methods for the detection of postoperative cerebral ischemia and how multidisciplinary collaborations, including endovascular interventions, should be considered to improve patient outcomes.

Perioperative Care of Patients at High Risk for Stroke During or After Non-cardiac, Non-neurological Surgery: 2020 Guidelines From the Society for Neuroscience in Anesthesiology and Critical Care.

Perioperative stroke is associated with considerable morbidity and mortality. Stroke recognition and diagnosis are challenging perioperatively, and surgical patients receive therapeutic interventions less frequently compared with stroke patients in the outpatient setting. These updated guidelines from the Society for Neuroscience in Anesthesiology and Critical Care provide evidence-based recommendations regarding perioperative care of patients at high risk for stroke.

Timing and Risk Factors Associated With Postoperative Stroke in Vascular Surgery Patients Using Time-Varying Coefficients From a Cox Model.

Background: Mechanisms of postoperative stroke are poorly understood, particularly for strokes occurring after uneventful emergence from anesthesia. We sought to create a model to study retrospectively the timing and associations for stroke in a high-risk surgery population.

Methods: Using a large prospective database containing detailed information on the occurrence and timing of stroke, we identified patients undergoing procedures involving the distal vascular (DV) and the cerebral vascular (CV) to assess the association between perioperative factors and stroke.

Recognition and Management of Perioperative Stroke in Hospitalized Patients.

We sought to characterize stroke management and outcomes in a postoperative population. By using the electronic medical records, we identified 39 patients suffering perioperative stroke after noncardiac and nonneurosurgical procedures for whom documentation of management and outcomes was available. Thirty-three strokes occurred during admission, whereas 6 occurred after discharge and were recognized upon return to the hospital.

Perioperative care of patients at high risk for stroke during or after non-cardiac, non-neurologic surgery: consensus statement from the Society for Neuroscience in Anesthesiology and Critical Care*.

Perioperative stroke can be a catastrophic outcome for surgical patients and is associated with increased morbidity and mortality. This consensus statement from the Society for Neuroscience in Anesthesiology and Critical Care provides evidence-based recommendations and opinions regarding the preoperative, intraoperative, and postoperative care of patients at high risk for the complication.

Web-based educational activities developed by the Society for Neuroscience in Anesthesiology and Critical Care (SNACC): the experience of process, utilization, and expert evaluation.

Background: Web-based delivery of educational material by scientific societies appears to have increased recently. However, the utilization of such efforts by the members of professional societies is unknown. We report the experience with delivery of educational resources on the Web site of the Society for Neuroscience in Anesthesiology and Critical Care (SNACC), and utilization of those resources by members.

Incidence, predictors, and outcomes of perioperative stroke in noncarotid major vascular surgery.

Background: Perioperative stroke is a potentially catastrophic complication of surgery. Patients undergoing vascular surgery suffer from systemic atherosclerosis and are expected to be at increased risk for this complication. We studied the incidence, predictors, and outcomes of perioperative stroke after noncarotid major vascular surgery using the American College of Surgeons National Quality Improvement Program database.

Cerebral perfusion pressure below 60 mm Hg is common in the intraoperative setting.

Background: Maintaining adequate cerebral perfusion pressure (CPP) is of clinical concern in patients with neurological injury. Although there are extensive data on CPP in the ICU setting, there has been little quantitative study of CPP in the intraoperative setting.

Methods: We retrospectively analyzed the electronic intraoperative records of neurosurgical and trauma patients with concurrent intracranial and arterial pressure monitoring devices in continuous use for ≥45 minutes to calculate CPP (=mean arterial pressure-intracranial pressure).

Fatal case of intracerebral hemorrhage during gamma knife treatment for metastases.

This case report presents a patient suffering acute fatal intracranial-intratumoral hemorrhage during a gamma knife treatment session. Acute hemorrhage during a radiosurgery session is extremely rare and a plausible cause for this case is discussed along with a literature review of previously reported incidents. The patient was a 71-year-old male presenting with three large intracranial lesions and an underlying primary renal cell carcinoma malignancy.
