BORGES, P.A. et al. Cardiorespiratory variables, bispectral index and recovery of anesthesia in dogs anesthetized with isoflurane, treated or not with tramadol. Arq. Bras. Med. Vet. Zootec. [online]. 2008, vol.60, n.3, pp. 613-619. ISSN 1678-4162. http://dx.doi.org/10.1590/S0102-09352008000300014.
It was studied fortuitous cardiorespiratory and bispectral index changes in dogs anesthetized with isoflurane associated or not to tramadol. Sixteen dogswere distributed in two groups named CG (control group) and TG (tramadol group). General anesthesia was induced in all animals with isoflurane via mask. After 10 minutes, the animals of CG received 0.05ml/kg of saline solution at 0.9%, and TG received 2mg/kg of tramadol, both via intramuscular. It was evaluated heart rate, systolic, diastolic and mean arterial pressures; electrocardiography; respiratory rate; oxihemoglobin saturation; end tidal carbon dioxide; bispectral index and recovery of anesthesia. The administration of tramadol in dogs anesthetized with isoflurane did not produce changes in cardiorespiratory variables, bispectral index and anesthetic recovery time. In addition, this association promoted good quality of anesthetic recovery.
