Results of verification of the sole use of peripheral nerve electrolocation (PNE) and ultrasound (US)-guided technique to block the femoral nerve (FN) by a dorsal approach in experimental cats
| Verification of the FN block | Group 1 PNE | Group 2 US |
|---|---|---|
| Evaluation of the motor blockade | ||
| Score 2 | 6/8 | 7/8 |
| Score 1 | 1/8 | 1/8 |
| Score 0 | 1/8 | 0/8 |
| Time required (mins) | ||
| Time to perform the block | 6.3 ± 4.4 (1–10) | 2.7 ± 0.9 (2.0–4.1) |
| Onset time | 6.0 ± 2.0 (4–10) | 7.0 ± 2.0 (4–10) |
| Duration time of block | 47.0 ± 10.0 (35–64) | 59.0 ± 18.0 (35–95) |
Data presented as mean ± SD (range) (n = 8)
Score 2 = complete motor blockade (inability to stand and walk, knee in extension touching the floor, limb paralyzed); score 1 = partial motor blockade (incomplete ability to bear weight, incomplete flexion of the stifle, muscle tone weaker than in the contralateral limb); score 0 = normal motor response (normal ability to walk or stand)
