Does Saline Injection Around Phrenic Nerve Reduce Incidence of Diaphragmatic Paresis Following Interscalene Block?

Ireland36 participantsStarted 2016-10

Plain-language summary

Hemi-diaphragmatic palsy is a common undesirable effect of interscalene block, with an incidence of up to 100%. Mechanism of palsy is thought to be related to spread of local anaesthetic anterior to the anterior scalene muscle. We hypothesize that by injecting saline in this anatomical location prior to performing an interscalene block the incidence of phrenic palsy will be reduced.
