Multicenter Study Comparative Study Clinical TrialPsoas Versus Femoral Blocks: A Registry Analysis of Risks and Benefits.
Psoas blocks are an alternative to femoral nerve blocks and have the potential advantage of blocking the entire lumbar plexus. However, the psoas muscle is located deeply, making psoas blocks more difficult than femoral blocks. In contrast, while femoral blocks are generally easy to perform, the inguinal region is prone to infection. We thus tested the hypothesis that psoas blocks are associated with more insertion-related complications than femoral blocks but have fewer catheter-related infections. ⋯ ID NCT02846610.
