Abstract:
The objective of the study was to evaluate the efficacy of glycopyrrolate, fentanyl citrate, triflupromazine hydrochloride, midazolam and ketamine hydrochloride induction with isoflurane maintenance for the repair of tibial fractures in dogs. In the present study, a total of 12 dogs with tibial fractures were divided into 2 groups of 6 dogs each. The anaesthetic protocol used in group-I was glycopyrrolate, fentanyl citrate, triflupromazine hydrochloride and ketamine hydrochloride induction with isoflurane maintenance. In group-II, glycopyrrolate, fentanyl citrate, midazolam and ketamine hydrochloride induction with isoflurane maintenance was used. Qualitative parameters such as abolition of reflexes, degree of analgesia, degree of muscle relaxation and physiological parameters such as heart rate, respiratory rate and temperature were recorded at the 0^th minute prior to induction and at the 15^th, 30^th, 60^th and 90^th minute after induction in both groups. Both the anaesthetic protocols provided safe and satisfactory anaesthesia in dogs undergoing tibial fracture repair. However, the dogs in group-II showed superior abolition of reflexes, analgesia and muscle relaxation as compared to group-I dogs at 15 minutes after induction. Thereafter, there was excellent analgesia and muscle relaxation with abolition of reflexes throughout the surgery in both groups.
