This study looked at the success rates of femoral vs proximal tibial IOs in the prehospital setting. Over a 9 year period, there were 163 pediatric patients who received either a tibial or femoral IO. Femoral IOs were introduced into the EMS protocol in this study area in 2015 as a location option and were the recommended site starting in 2019. The success rate of femoral IO placement was 89% and for proximal tibial sites was 84.7%. After further data analysis the study found an adjusted odds ratio of 2 for successful IO placement in the distal femur compared to the proximal tibia. The complication rates for both sites were similar.
Bottom line: This study suggests that the distal femur is a reasonable site for IO access in the pediatric population.
