She requires oxygen therapy and admission. It is busy in the ED. This patient has been waiting for 3.5 hours. Her bed is ready in the ward.

A 55-year-old male patient came to the emergency department with the symptoms of acute onset of severe chest pain with radiation to the back, cold sweating, and nausea. He had mild shortness of breath and his pain was most severe at onset. Physical examination revealed blood pressure: 210/120mmHg, heart rate: 101/min, respiratory rate: 20/min (SpO2 97% at room air), irregular heart beat without murmur, and clear breathing sound over the bilateral lung fields. The electrocardiogram (ECG) revealed atrial fibrillation with rapid ventricular response. Chest computed tomography showed a dissecting aortic aneurysm, from the descending thoracic aorta to the left common and external iliac artery. Therefore, a clinical diagnosis of aortic dissection, Stanford B was made. We wondered whether nicardipine was suitable to control his blood pressure and improve the outcome.

On return to the ED, her right pupil appears dilated and her GCS is now 10 (E2M4V4). The neurosurgical registrar is in theatre for the next 20 minutes. You intubate and ventilate the patient and wonder whether hypertonic saline would be better than mannitol at controlling the patient's ICP acutely.

An agitated 24-year-old patient with a history of schizophrenia enters the emergency department, and becomes aggressive and hostile towards staff and patients. De-escalation techniques fail, and the patient will not take oral medication or allow intravenous cannulation.

Your hospital is on take for PCI. You have referred him to the cardiology registrar informing that you have initiated the treatment with Aspirin, Clopidogrel and Fragmin. He tells you that he is taking this patient to the angiography suite in the next hour.

You wonder what this drug is and how this fares in comparison with Clopidogrel.

An adult male presents to the ED with flashes and floaters, and a curtain falling across the eye. Following standard ocular examination, there is a suspicion of RD, PVD or VH. Could ocular ultrasound performed by an ED physician help in confirming the diagnosis and accelerate his further management?

A 25 year old man is brought into the emergency deparment by his brother who found him unconscious at home. He is pinpoint pupils, a respiratory rate of 6. ABGs show a pH of 7.05 and a pCO2 of 14kPA. In light of the suspected opiate overdose you administer naloxone, but wonder if it would have been beneficial to treat the respiratory acidosis first.

You wonder whether the medical SHO cohort know something that you and SIGN do not, so decide to evaluate the evidence yourself.

His BP is 130/70mm Hg, heart rate 90 beats per minute, respiratory rate 23/min, and temperature 37.3°. He denies any history of trauma.
