Symptoms of stroke – weakness, facial droop, slurred speech. vision loss, vertigo, ataxia, confusion or changes to mental status.  







The “typical” stroke workup – blood glucose level, CTH non-con, CTA head/neck, CT Perfusion, CBC BMP Troponin EKG CXR and Coags. 







Common stroke mimics – hypoglycemia, drug/alcohol intoxication, Bell’s palsy, aortic dissection, complex migraines, and seizure with Todd’s paralysis.  







Management/treatment – thrombolytics (within 4.5 hrs), thrombectomy (within 24 hrs) , and blood pressure control (185/110 if treating, 220/120 if no treatment). 







Remember that time is brain, so move fast!

AHA Stroke – “Getting the Gist Across Is Enough for Informed Consent for Acute Stroke Thrombolytics”

You are working at Clerkship General when one of the nurses comes and grabs you. “Hey doc, we need you in bed 10. I think this patient is having a stroke.”







Initial Vitals:







HR: 51







BP: 201/98







Temp: 98.0F







RR: 18







O2: 99% (Room Air)







Critical Actions:









* Check a Blood Glucose







* Activate a Stroke Alert







* Assess Contraindications to tPA







* Consent for tPA







* Transfer via Air for Thrombectomy

* Common during the first year of life as well as during puberty







* Presents with nausea/vomiting, abdominal pain, and/or testicular pain







* ALWAYS examine a child for signs of torsion who presents with abdominal pain (especially lower abdominal pain)







* Look for tenderness, firmness, high riding testicle or testicle with unequal lie, swelling, and the absence of a cremasteric reflex







* Consult Urology IMMEDIATELY if you have high suspicion, otherwise proceed to ultrasound







* Ultrasound is only 85% sensitive, so clinical gestalt can trump even a negative US







* Attempt manual detorsion if there will be a significant delay to surgery

You are working at Clerkship General when the next patient is put into your rack. It is an 8 year-old male with vomiting
