[Efficient ambulatory and post-discharge thromboprophylaxis with fully automated pens].

Efficient prophylaxis of deep vein thrombosis is very important during and after hospitalisation as well as for outpatients. In a prospective randomised trial, a new automatic pen for subcutaneous injections of low molecular heparin was studied with 489 injections in 51 patients. The automatic pen with a covered needle allows a safe and standardised subcutaneous administration of low-molecular heparin with good patient comfort and at no additional costs.
