Investigating the suitable mixing ratio of 0.375% ROP and perfluoropropane UCA: Operation diagram. A: The ultra high frequency ultrasonic probe is shown to collect images at different dilution multiples. B: Figure shows the stratification diagram of the abdominal fascia of rabbits, EO, the external oblique muscle of the abdomen; IO, internal obliquus abdominal muscle; TA, transverse abdominalis; C: Schematic diagram of block puncture path at the transverse abdominis plane is shown. The red arrow indicates that the needle tip enters the transverse abdominis plane. D: The area highlighted by the orange arrow in the figure is the perfluoropropane UCA development area
