“…Positive stimulus was considered, that is, with one or more of the following responses: vocalization, flapping, sudden movement of the contralateral to stimulated limb, head and tail raising (Nicolau et al 2002, Mercado et al 2008, Escobar 2010, Kim et al2011, Pavez et al2011, Chan et al2013. This was well determined and standardized in this study because the lack of this standardization is a major cause of MAC value variability (Oliveira et al 2014).…”

“…This is not observed in the digital or interdigital clamping methods, as there is no standardization of the clamping location, type of clamping and the amount of pressure applied at the point. It is only known that it is done at the level of the clamping rack, and in the other points the authors made their own adaptations (Ludders et al 1988, 1989, Naganobu & Hagio 2000, Nicolau et al 2002, Mercado et al 2008, Kim et al 2011, Chan et al 2013, Oliveira et al 2014.…”

Influence of social stress on value of minimal anesthetic concentration of isuflurano in guan (Penelope obscura) captured in wildlife

This study aimed to determine and evaluate whether there are differences in values of MAC in wildlife captured guan (Penelope obscura) under different conditions of social stress. This study used 27 bird species guan (P. obscura), divided into two groups: animals kept in the same enclosure (Collective Group) and animals kept in individual cages (Individual Group). The research was conducted at the Advanced Research Base of IBAMA, Painel/SC, and at the Clinical Veterinary Hospital of the “Universidade do Estado de Santa Catarina”, Lages/SC. The birds were captured using network trap with manual disarmament and transported to the Veterinary Hospital in cages. The animals were fasted for 2 to 6 hours before the procedure; anesthetic induction was performed with isoflurane for instrumentation. The isoflurane CAM was placed in the target value 1.3v% in the first animal of each group, and waited 15 minutes for the nociceptive (electric) stimulus, in the value of 50 hertz and 50mA, held in faradic form (3 consecutive simple stimuli, followed by 2 continuous stimuli). The stimulus was performed on the lateral side of the left pelvic limb in the tibiotarsal region, and the electrodes were fixed with a 22G needle at a distance of 5cm between them. The bird’s responses to the stimulus were considered positive (wing movements, head or vocalization) or negative (not presented movements of wings, head or vocalization) and the MAC value of the animal was recorded. Negative responses reduced next birds’ MAC value by about 10%, and MAC positive responses increased by about 10%. Statistical analysis was done by methods up and down and analyze quantal for MAC and paired t-test for equivalent or t-test for variances not equal variances for the physiological variables. At the end of the experiment, the birds were reintroduced in the same capture area. The MAC value of isoflurane in the Collective Group was 1.4v% and the Individual Group 1.9v% to 0.903atm. It is observed that guan (P. obscura) in the Collective Group showed lesser anesthetic resistance to isoflurane than the birds in the Individual Group, showing that some levels of social stress can influence the MAC values of the isoflurane.

Peccaries are wild mammals belonging to the Tayassu genus that are found almost everywhere in the Americas and have demonstrated great potential as an experimental model for scientific investigations. Twelve healthy adult animals were sedated to perform echocardiographic examinations in B, M and Doppler mode. The variables that exhibited statistically significant correlation coefficients with weight were LVFWd, LVIDd, LVIDs, E wave, A’RV, MAM, and TAPSE. The HR exhibited a negative relationship with the IVRT. The LA variable showed a positive correlation with the AO. The MAM exhibited correlations with the LVIDd and LVIDs. The TAPSE showed positive correlations with the E’RV and A’RV. The present study provides the first reference values for echocardiographic measurements in B, M and Doppler modes from peccaries anesthetized with ketamine and midazolam. Echocardiography was easy to perform in collared peccaries, and the collected data revealed values that can aid in their clinical management and conservation.
