A preoperative evaluation is advised for all children and adolescents having elective surgery with anesthesia. The evaluation assesses medical and psychosocial factors that may affect surgery timing and identifies underlying conditions that may require evaluation or management before surgery. The evaluation also classifies the patient's American Society of Anesthesiologists' risk category. ⋯ The HEMSTOP questionnaire can identify patients who have coagulation disorders. A pregnancy test should be considered for all adolescents who are postmenarchal on the day of surgery. Many children have anxiety about surgery, which can be reduced by educational pamphlets, videos, coaching provided to parents the week before surgery, and a parental presence during the induction of anesthesia.

Stroke accounts for significant morbidity and mortality and is the fifth leading cause of death in the United States, with direct and indirect costs of more than $100 billion annually. Expedient recognition of acute neurologic deficits with appropriate history, physical examination, and glucose testing will help diagnose stroke and rule out mimicking presentations. The National Institutes of Health Stroke Scale should be used to determine stroke severity and to monitor for evolving changes in clinical presentation. ⋯ Patients with cerebellar symptoms should be evaluated with a HINTS (head-impulse, nystagmus, test of skew) examination because it is more sensitive for cerebellar stroke than early magnetic resonance imaging. Additional cerebrovascular imaging should be considered in patients with large vessel occlusions presenting within 24 hours of last known well to assess benefits of endovascular interventions. Once initial interventions have been implemented, poststroke evaluations such as telemetry, echocardiography, and carotid imaging should be performed as clinically indicated to determine the etiology of the stroke.
