Comparative Study
The utility of shock index in differentiating major from minor injury.
The importance of early recognition of hemorrhagic shock and its effects on outcome have long been recognized. Traditional vital signs are relatively insensitive as early diagnostic markers of hemorrhage. The shock index (SI); heart rate (HR) divided by systolic blood pressure (SBP), has been suggested as such a marker. We tested the diagnostic utility of the SI in differentiating major from minor injury in trauma patients. ⋯ The SI can be a valuable tool, raising suspicion when it is abnormal even when other parameters are not, but is far too insensitive for use as a screening device to rule out disease. A normal SI should not lower the suspicion of major injury.

Case Reports
Diltiazem poisoning treated with hyperinsulinemic euglycemia therapy and intravenous lipid emulsion.
Intravenous lipid emulsion (ILE) has been proposed as a rescue therapy for severe local anesthetic drugs toxicity, but experience is limited with other lipophilic drugs. An 18-year-old healthy woman was admitted 8 h after the voluntary ingestion of sustained-release diltiazem (3600 mg), with severe hypotension refractory to fluid therapy, calcium salts, and high-dose norepinephrine (6.66 μg/kg/min). ⋯ Diltiazem is a lipophilic cardiotoxic drug, which could be sequestered in an expanded plasma lipid phase. The mechanism of action of ILE is not known, including its role in insulin resistance and myocardial metabolism in calcium-channel blocker poisoning.

Comparative Study
Therapeutic hypothermia after cardiac arrest in Lower Austria--a cross-sectional survey.
This study was undertaken to evaluate the use of therapeutic hypothermia (TH) after cardiac arrest in Lower Austria. A questionnaire was sent to intensive care units (ICUs) in Lower Austria. Methods of inducing and maintaining hypothermia, the practise of rewarming, concomitant therapies and reasons not to cool were documented. ⋯ Reasons not to cool were insufficient staff resources (n=4, 17%), technical complexity of cooling (n=4, 17%) and too little information (n=3, 13%). In conclusion, TH has been poorly implemented in Lower Austria. The reasons for not using hypothermia could possibly be dispelled by education.

Atraumatic splenic rupture is an uncommon but poorly defined clinical condition. Its diagnosis may be missed or delayed because of low clinical suspicion, especially in the absence of trauma. The primary aim of this study was to describe the experience with atraumatic splenic rupture in a district general hospital. ⋯ In four cases, no pathological abnormality was identified (atraumatic-idiopathic); abnormal pathologies (atraumatic-pathological) in the remaining three were amyloidosis, lymphoma and focal thrombosis. A high index of suspicion should be maintained by emergency physicians and surgeons during initial evaluation of these patients. Computed tomography scan facilitates the diagnosis and early total splenectomy is often needed.

As a result of national guidance in the UK, the number of computed tomography brains performed in patients with minor head injury has increased significantly. The aim of this survey was to establish the requirement for general anaesthesia and tracheal intubation in the management of emergency department patients requiring an urgent computed tomography of the brain. About 300 consecutive scans in emergency department patients were reviewed. The majority (>90%) did not require anaesthetic airway management despite an overall acute scan diagnosis rate of around 25% and 30 day mortality of 10%.
