The objective with this review to present relevant information about the cardiorespiratory effects and associations of the main drugs used for epidural anesthesia in cats, such as lidocaine, tramadol, morphine, fentanyl, drugs α2-agonists and ketamine. The injected drugs and associations in this way develop minimal cardiorespiratory changes and ventilation of healthy feline patient, without causing severe alkalosis or acidosis, indicating that the epidural is an efficient technique, safe, and that the drugs used in this way promote less pronounced effects when used systemically. It should, however, assessing the patient beforehand, so as to choose the best combination, since the administration of opioids cause respiratory depression.
