Peripheral nerve blocks (PNBs) are of concern in patients with underlying neurological disease.1 The response to electrical stimulation may be impaired, increasing the risk of nerve damage.1 The use of ultrasound has been described only in one case of neurofibromatosis.2 We describe here the use of ultrasound-guided PNBs in hypertrophic peripheral neuropathy [Charcot–Marie–Tooth disease type 1 (CMTD1)] and degenerative disease [Friedreich's ataxia (FRA)].
