Key Points

To investigate the effects of dexmedetomidine continuously infused on insulin secretion and glucose tolerance in healthy dogs.
Administered different doses of dexmedetomidine (DEX)
Monitored insulin secretion levels
Assessed glucose tolerance through monitoring glucose levels over time
Medium- and high-dose DEX impaired glucose tolerance
Low-dose DEX did not significantly disrupt glucose homeostasis under controlled conditions

Implication

Observational analysis suggests dexmedetomidine infusion may impair glucose tolerance in healthy dogs, indicating caution in clinical use.

Abstract

Medium- and high-dose DEX CRI may impair glucose tolerance in healthy dogs, whereas the clinically used low-dose regimen appears unlikely to disrupt glucose homeostasis under controlled conditions.
