There is no difference in the effectiveness of the two most commonly used methods for administering medication during out-of-hospital cardiac arrest. This is shown in a large new clinical study by Aarhus University and Prehospital Services, Region Midtjylland, which compared two ways of accessing the bloodstream: a standard needle in a vein (venous catheter) and a so-called intraosseous needle, which is inserted into the bone marrow . "When a person suffers cardiac arrest outside the hospital, it is crucial to quickly access the bloodstream to administer life-saving medication.
We investigated which method is best," explains Lars Wiuff Andersen, professor and physician at the Department of Clinical Medicine, Aarhus University, Prehospital Services, Region Midtjylland, and Aarhus University Hospital. Venous catheter or intraosseous needle? Until now, health care professionals have preferred using a venous catheter, but it can be difficult to place as veins may collapse during cardiac arrest. The intraosseous needle, inserted either into the shinbone or upper arm, can be faster and easier to use in an emergency.
Therefore, it's interesting to investigate the effectiveness of both methods, explains Andersen. The study, based on data from nearly 1,500 cardiac arrest patients across Denmark, showed that about 30% of patients in both groups had their blood circulation restored. "The two methods proved to be equally effective in restoring blood circulation and saving lives.
