[Nerve-root damage from local injections (author's transl)].

Paravertebral injections of local anaesthetics (procaine hydrochloride, frequencly in combination with other substances) may damage cervical or lumbosacral nerve roots, depending on the site of injection. Five such iatrogenic lesions are described. Paravertebral injections of local anaesthetics also carry the risk of irreversible paraplegia and such treatment should therefore not be given in the cervical and lumbar segments.
