Medical Puncture Needle For Intramedullary Blood Access

Establishing access needle Speed and success rate Establishing a bone marrow access blood needle is very quick. In the pre-hospital emergency treatment of traffic accidents, the average time of the bone marrow access group was 2.4 min, and that of the transvenous group was 11.8 min. The average time for the establishment of venous access in children with respiratory and cardiac arrest was 7.8 min, with 24% of patients taking more than 10 min. However, the establishment of lower limb IO only takes 1~2 min and does not interfere with resuscitation operation. The success rate for establishing a bone marrow access needle was about 80% in the emergency room and 78% when administered by medical staff outside the hospital. 85% of children aged 1 to 2, 67% of children aged 3 to 9, and 50% of children aged over 10. For infants with the most difficult venous access to establish, the success rate of establishing blood puncture needle through marrow cavity access is high.
