Evaluation of the quality of anaesthesia induction, surgical conditions and recovery phase
| Parameter | Score | Description |
|---|---|---|
| Induction score | 1 (Excellent) | Sinks smoothly to the ground, no forward-backward movement, no excitement |
| 2 (Good) | Sinks smoothly to the ground, slight forward-backward movement, slight head or limb twitching | |
| 3 (Fair) | Inadequate relaxation, forward-backward movement, visible ataxia, twitching, slight limb paddling | |
| 4 (Poor) | Inadequate relaxation, considerable movement and ataxia, marked limb paddling | |
| 5 (Very poor) | Failure to reach recumbency | |
| Recovery score | 1 (Excellent) | Quiet, 1 or 2 coordinated efforts to sternal and standing positions, minimal to no ataxia once standing |
| 2 (Good) | Quiet, 1 or 2 slightly uncoordinated efforts to sternal and standing positions, mild ataxia once standing | |
| 3 (Fair) | Multiple (>2) quiet attempts to sternal and standing positions, mild to considerable ataxia once standing | |
| 4 (Poor) | Multiple (>2) uncoordinated attempts to sternal and standing positions | |
| 5 (Very poor) | Recovery resulting in major injury | |
| Surgical score | 1 (Excellent) | Good muscle relaxation, easy extraction of the testicle |
| 2 (Good) | Moderate retraction of the cremaster muscle | |
| 3 (Fair) | Difficult extraction of the testicle | |
| 4 (Poor) | Movements of the horse during surgery, reinjection required |
