Block Characteristics (a) Imaging and needling times. Imaging, but not needling time was significantly lower for PICB than PVB (p = 0.245, p = 0.039, respectively). (b) Length of needle in body and distance from midline. Distance from midline was greater for PICB (p < 0.001), but no significance difference in length of needle in body(p = 0.363) was seen (Mann Whitney U-test). PICB: proximal intercostal block, PVB: paravertebral block
