[Alternatives to the intravenous route in emergency situations].

Patients in emergency situations or life distress most often need a intravenous line (IV) to give them the medications they need. The IV route is the preferred route to treat most of the patients in emergency situations out of hospital or in the emergency room but can be very tricky to obtain. Various alternatives have been developed, such as the intraosseous route, particularly useful in cases of venous collapse (shock, cardiorespiratory arrest), the intramuscular route (anaphylaxis, sedation) or the intranasal route (status epilepticus, analgesia). This article reviews the indications, contraindications and pharmacology of these different routes.
