Tourniquets are an effective means of arresting life-threatening external haemorrhage from limb injury. Their use has not previously been accepted practice for pre-hospital civilian trauma care because of significant concerns regarding the potential complications. ⋯ This review explores the potential problems and mistrust of tourniquet use; explains the reasons why civilian pre-hospital tourniquet use may be necessary; defines the clear indications for tourniquet use in external haemorrhage control; and provides practical information on tourniquet application and removal. Practitioners need to familiarise themselves with commercial pre-hospital tourniquets and be prepared to use one without irrational fear of complications in the appropriate cases.

Comparative Study
Use of the prehospital ECG improves door-to-balloon times in ST segment elevation myocardial infarction irrespective of time of day or day of week.
The use of the prehospital electrocardiogram (ECG) to identify patients with ST-segment elevation myocardial infarction (STEMI), coupled with a centralised system to alert the cardiac catheterisation team in preparation for prompt intervention, has been shown to reduce door-to-balloon times (DBT) effectively. A confounding variable in prolonging the recommended 90 min DBT is the time of day or day of the week of patient presentation. We postulated that use of the prehospital ECG, coupled with an emergency department initiated "Cath Alert" system, could neutralise DBT delays related to time of day or day of week. ⋯ Variables such as time of day and mode of presentation have an impact on achieving currently recommended DBT in patients with STEMI. With the addition of each prehospital variable in succession-that is, arrival by emergency medical services, Cath Alert system, and the prehospital ECG-the DBT can be progressively shortened and the adverse "off hour effect" nullified.

The Livingston Paediatric Dose Calculator is presented and its use explained. It may be of benefit in emergency departments that do not regularly see large numbers of children requiring drug treatment.

A short cut review was carried out to establish whether octreotide can prevent rebound hypoglycaemia after sulfonylurea overdose. Fourteen papers were found using the reported searches, of which two presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are summarised in table 2. It is concluded that octreotide may be safe and effective in this situation.
