Summary
Four anesthetic protocols were compared for kitten neutering. Tiletamine/zolazepam offered the best analgesia in males but prolonged recovery in females, while opioids provided faster recovery.
Area of Science:
- Veterinary Anesthesiology
- Feline Surgery
- Pharmacology
Background:
- Neutering is a common surgical procedure in kittens.
- Effective anesthetic protocols are crucial for minimizing pain and ensuring rapid recovery.
- Evaluating different injectable anesthetic combinations is essential for optimizing feline surgical care.
Purpose of the Study:
- To compare the efficacy of four intramuscular anesthetic protocols in kittens undergoing neutering.
- To assess preanesthetic disposition, sedation, analgesia, muscle relaxation, induction, and recovery characteristics.
- To determine the optimal anesthetic protocol for pediatric feline neutering.
Main Methods:
- Forty-eight male and 48 female kittens (6-14 weeks old) received one of four intramuscular anesthetic protocols: tiletamine/zolazepam (TZ), midazolam/ketamine, atropine/midazolam/ketamine/butorphanol (AMKB), or atropine/midazolam/ketamine/oxymorphone (AMKO).
- Parameters evaluated included sedation quality, handling ease, induction time and quality, sternal recumbency, standing time, and recovery quality.
- Analgesia and muscle relaxation were assessed in males; extubation time was recorded in females.
Main Results:
- All protocols provided rapid sedation and smooth induction.
- Tiletamine/zolazepam (TZ) induced the best analgesia in males but resulted in the longest recovery times in both sexes.
- Opioid-based protocols (AMKB, AMKO) led to shorter recovery times in males; TZ facilitated intubation without supplemental inhalants in females but prolonged sternal and standing times and worsened recovery quality.
Conclusions:
- Tiletamine/zolazepam (TZ) provides excellent analgesia for male kitten castration but is associated with prolonged recovery.
- Opioid-containing protocols offer faster recovery times in male kittens.
- While TZ aids intubation in female kittens, it negatively impacts recovery quality and duration, suggesting alternative protocols may be preferable.
