As a result of the potential for retroperitoneal hematoma, lumbar plexus and paravertebral nerve blocks benefit precisely the same suggestions as for neuraxial injections.

Thanks to the possibility of retroperitoneal hematoma, lumbar plexus and paravertebral nerve blocks merit a similar tips as for neuraxial injections.
