Randomized Controlled TrialAn Iliopsoas Plane Block does not Cause Motor Blockade - a Blinded Randomized Volunteer Trial.
A femoral nerve block relieves pain after total hip arthroplasty, but its use is controversial due to motor paralysis accompanied by an increased risk of fall. Assumedly, the iliopsoas plane block (IPB) targets the hip articular branches of the femoral nerve without motor blockade. However, this has only been indicated in a cadaver study. Therefore, we designed this volunteer study. ⋯ We observed no significant reduction of maximal force of knee extension after an IPB. The injectate was contained in a fascial compartment previously shown to contain all sensory branches from the femoral nerve to the hip joint. The clinical consequence of selective anesthesia of all sensory femoral nerve branches from the hip could be a reduced risk of fall compared to a traditional femoral nerve block. Registration of Trial: The trial was prospectively registered in EudraCT (Reference: 2018-000089-12, https://www.clinicaltrialsregister.eu/ctr-search/search?query=2018-000089-12).

Clinical TrialLongitudinal neural exposure to local anesthetic and nerve block duration: a retrospective analysis of experimental data from healthy volunteer trials.
Characteristics of a nerve block depend on the distribution of local anesthetic (LA) close to the nerve. The relationship between longitudinal distribution of LA and nerve block characteristics has not been investigated in viv o, but one in vitro study showed decrements in action potential amplitudes with increasing exposure length. We describe the influence of longitudinal neural exposure to LA on nerve block duration adjusted for other likely influential factors. ⋯ Longitudinal neural exposure to LA was significantly associated with nerve block duration. LA dose was the strongest determinant for block duration whereas LA volume had no influence.

Interventional techniques for managing spinal pain, from conservative modalities to surgical interventions, are thought to have been growing rapidly. Interventional techniques take center stage in managing chronic spinal pain. Specifically, facet joint interventions experienced explosive growth rates from 2000 to 2009, with a reversal of these growth patterns and in some settings, a trend of decline after 2009. ⋯ Interventional techniques, facet joint interventions, facet joint nerve blocks, facet joint neurolysis.
