Brazil has one of the greatest avifauna riches in the world, which makes the country one of the
most important in terms of investments in conservation. The mangrove parrot is not an
endangered species, but it also suffers from animal trafficking and habitat loss. With the
expansion of wildlife and wild fauna conservation programs, there is a visible increase in
problems when handling these birds, making it necessary to study safe drugs for their
management. The literature on anesthetic procedures in these species is scarce, generating
insecurity in some cases when using some protocols. The objective of this study was to evaluate
the use of the combination of ketamine 35 mg/kg, dexmedetomidine 35 μg/kg and butorphanol
0.4 mg/kg, in the chemical containment of mangrove parrots, observing the effects on
physiological variables such as: glycemia, heart rate (HR), respiratory rate (RR),
oxyhemoglobin saturation (SpO2), systolic and diastolic blood pressure and body temperature.
We used 9 healthy, adult individuals, captives from the Cerrado Institute, in Araguaína,
Tocantins. After administration of the protocol, the animals were observed for the latency
period, and this period was properly timed, as well as the stable period. The aforementioned
parameters, with the exception of blood glucose, were measured 5 minutes after the application
of the drugs (M0) and every 5 minutes thereafter (M1-M8), totaling 40 minutes of
contemplation of the anesthetic effects. Among the parameters evaluated, HR and T0C showed
a statistically significant decrease throughout the anesthetic period. The RR showed no
statistical difference and all animals remained stable. SpO2 throughout the anesthetic period
demonstrated statistical differences, but considering that in birds, the ideal saturation level
needs to be maintained with values greater than 90%, in the respiratory status of the study,
increasing values in M3 and M4, followed by mild oscillations, could be interpreted as positive,
with the oxygenation recorded being considered satisfactory. SBP and DBP remained stable
and no statistical differences were seen in these measurements. Blood glucose, measured at M0
and M3, showed a slight increase, without a significant difference capable of justifying an
adverse effect. After 40 minutes of anesthetic monitoring, atipamezole 0.035 mg/kg was applied
as a reverser, and the birds were kept in a quiet environment throughout the recovery period.
When evaluating the different phases of post-anesthetic recovery, it was considered positive, as
no complications were observed, occurring smoothly, within a previously stipulated time. The
quality of the anesthetic protocol used was considered very good and could be used safely in
the species studied.
