The intranasal route is a good alternative because is painless and easy to perform in birds. The objective of this study was to evaluate the anesthetic effects of S+ ketamine and midazolam administered by intranasal or intramuscular route in pigeons. Twelve animals were used in a randomized and crossover design. Animals received two treatments with 2-weeks interval. IM group: animals received 20mg/kg of S+ ketamine and 3.5mg/kg of midazolam by intramuscular route (pectoral muscles); IN group: animals received the same protocol by intranasal route. Parameters evaluated were: onset of action, time of duration in dorsal recumbency; total time of anesthesia and side effects. Statistical analysis was performed using Wilcoxon test and the differences were considered significant when P<0.05. Onset of action was 30 [30-47.5] and 40 [30-50] seconds for IM and IN respectively. Time of duration in dorsal recumbency was 59 [53.25-65] and 63 [37-71.25] minutes for IM and IN respectively, without significant differences between treatments. Total time of anesthesia was 88 [86.25-94.5] and 68 [53.5-93] minutes for IM and IN, respectively, with significant difference between groups. The recovery time was lower for IN (15[4.25-19.5] minutes) compared with IM (32 [28.25-38.25] minutes). Two animals of each group presented regurgitation in the recovery period. It was concluded that S+ ketamine and midazolam administered intranasal is an acceptable method of drug delivery and can be used to promote anesthesia in pigeons. |
