Purpose

This study characterized the duration and frequency of ocular pain behaviours in cats before and after the administration of analgesia pre- and post- ophthalmic surgery.

Methods

Thirty adult cats (13 female and 17 male neutered; 6.6 ± 4.4 years; 4.2 ± 1.0 kg), including brachycephalic (n = 24) and non-brachycephalic breeds (n = 6), were enrolled in a prospective, controlled, blinded study.

n = 24

Results

± 42% vs 3 ± 9%
cats were unresponsive to their surroundings for less time after methadone
n = 24
More results

Cats were video-recorded undisturbed pre- and postoperatively as well as following the administration of methadone (0.3 mg/kg IM during premedication and 0.2 mg/kg IV postoperatively).

A veterinary behaviourist blinded to treatments evaluated pain behaviours.

Conclusion

This study identified pain behaviours in cats undergoing ophthalmic surgery that are modified by analgesic treatment, contributing to pain assessment in ophthalmology.
