A 36 year old female patient is admitted to the ICU following a significant burn injury, with more than 50% of the body surface area involved, sustained in gas exploding accident. She is being managed in accordance with Burn injury guidelines but in addition, since she had an high risk factor for stress-related UGI bleeding, she was prescribed Esomeprazole 40 mg i.v od, for stress-related upper gastrointestinal bleeding prophylaxis. However, this was changed to Ranitidine 50 mg i.v tid, two days later on the advice of the Gastroenterologist. Is there is any difference in benefit between the two drugs for the prevention of stress-related upper gastrointestinal bleeding?

A 30 yr old man who has been involved in a car crash has been brought to your ED. His GCS is 7 and he was intubated in ED and underwent trauma series CT. His CT cervical spine has been reported as normal. He is about to be transferred to ICU and you are wondering whether CT cervical spine alone can exclude unstable ligamentous injury?

A 35 year old triathelete presents to the emergency department following a long distance event. He feels dizzy, nauseated, fatigued and has some degree of confusion. A clinical diagnosis of symptomatic hyponatraemia is made when his arterial blood gas sample shows a sodium level of 120 mmol/L.

You receive an emergency call to a 75 year old male in a nursing home who is terminally ill. On examination you find the patient is peri-arrest with an irregular pulse and hypotensive at 57/35 and the nursing home staff state that the patient has a DNAR order but they are unable to produce the relevant documentation. You commence oxygen therapy, gain iv access and start fluid resuscitation before rapidly transporting to hospital. Afterwards you wonder what you would have done had the patient gone into cardiac arrest in the absence of a written Advance Directive.

A 23 year old male presents to the emergency department with a knee injury sustained whilst playing football. You diagnose a probable anterior cruciate tear and decide to immobilise the patient in a cricket pad splint. He has a family history of deep vein thrombosis. He is partially weight bearing. You wonder whether the splint will increase his risk of a venous thromboembolic (VTE) event and in particular whether there is any potential benefit from the use of thromboprophylaxis.

A 65 year old lady with no history of DVT/PE presents with acute onset unilateral calf swelling/tenderness. There is no history of trauma, recent surgery, and no infective symptoms. She is investigated with a D-dimer blood test which comes back at 8000 ng FEU/ml and undergoes a doppler US which is negative. What is the evidence to suggest an underlying malignancy?

A 55-year-old patient with high BMI and known COPD is brought to the Emergency Department by paramedics, complaining of sudden onset of severe difficulty in breathing. The patient has decreased air entry on the right side, the trachea is deviated to left and hyper-resonance is noted on the right side. A clinical diagnosis of tension pneumothorax is made and immediate needle decompression is indicated. You wonder which approach is better for immediate needle decompression - the anterior approach (2nd intercostal space, mid-clavicular line) or the lateral approach (5th intercostal space, anterior or mid-axillary line).

A patient has suffered a crush injury of his thigh and calf. You are concerned that he may go on to develop acute renal failure. You ask you Consultant if a urinary myoglobin assay might be useful in predicting this.

You have seen a 34 year old female with a lateral malleolus fracture, which is suitable for immobilisation in a below knee plaster cast. She had a previous DVT several years ago when her other leg was in plaster following a fracture. She is anxious not to have another one. You are aware of recent evidence suggesting that heparin prophylaxis may be beneficial in this situation. When you discuss this with the patient she asks you to quantify the risks of bleeding. You are unsure, but resolve to find out immediately.

A patient presents to your emergency department following an acute knee injury. You exclude a fracture and any acute significant meniscal or ligamentous injury and diagnose a knee sprain. You provide the patient with analgesia and RICE advice and wonder whether the application of a tubigrip will also help reduce their pain and lead to a quicker recovery.
