Efficacy of Preoperative Bilateral Thoracic Paravertebral Block in Cardiac Surgery Requiring Full Heparinization: A Propensity-Matched Study.
To assess the efficacy of preoperative bilateral paravertebral block (PVB) with general anesthesia (GA) in contributing to early extubation and decreasing opioid consumption in cardiac surgery. ⋯ This study demonstrated that preoperative bilateral PVB combined with GA contributed to early extubation in isolated first-time aortic valve replacement and coronary artery bypass grafting and in the reduction of intraoperative and postoperative fentanyl consumption.

The aim of this cadaveric study was to investigate the erector spinae plane block (ESPB) in lumbar region and to elucidate the possible mechanisms of action of these injections in lumbar radicular pain by means of detecting expected dye dispersion to the neural structures. ⋯ The involvement of the dorsal rami was found to extend up to the T12 level and down to the L5 spinal nerves. Although dye dispersion was detected on the dorsal root ganglion in all specimens, it was found to be limited to one or two levels, unlike the dorsal rami. In half of the specimens, distribution to the ventral ramus and posterior epidural space was observed.
