Ultrasound-assisted vs Landmark Based Intrathecal Administration of Nusinersen

key information

study id #: NCT04674618

condition: Muscular Atrophy, Spinal, Ultrasound

status: Recruiting


Intrathecal administration of Nusinersen, an antisense oligonucleotide capable of increasing Survival Motor Neuron protein production, has been tested in Spinal Muscular Atrophy (SMA) to improve motor function and survival. A feature of adult SMA patients is a progressive neuromyopathic scoliosis, so spinal nusinersen administration can be challenging. Landmark identification using a pre-procedure ultrasound (US) facilitates technical performance of spinal anesthesia and allows for the elimination of radiation exposure.

The aim of this randomized prospectic study is to determine if the US assistance for spinal administration of nusinersen is able to increase the proportion at successful 1st needle insertion of the needle. Secondary outcome measures are procedure time, patient satisfaction and prevalence of postdural puncture headache.

Patients will be randomlized to receive a US-assisted nusinersen administration or a landmark based nusinersen administration.

intervention: US-assisted nusinersen administration
