“…No entanto, a aplicação epidural em felinos é mais difícil que em cães, necessitando maior destreza do anestesista, devido ao tamanho do paciente, já que, não raramente, pode ocorrer punção subaracnoide. A presença de líquor não impede a realização desta técnica, no entanto, requer mais cuidado na punção, evitando-se movimentos excessivos e, se observada a presença de líquor, pode-se retroceder a agulha (TORSKE & DYSON, 2000). A falta de resistência na aplicação por si só não comprova a correta realização da técnica.…”

“…Leibetseder et al 13 showed moderate hypotension after ED In dogs, respiratory function is not impaired following extradural anesthesia, unless local anesthetic produce motor blockade of the phrenic nerve at cervical vertebra 1 . However, the use of epidural opioids, particularly morphine, has been associated with respiratory depression, mainly in people 15 .…”

“…Approximately 1mL of 2% lidocaine per 4.5kg of body weight will completely anesthetize the pelvic limbs and posterior abdomen within ten to 15 min after administration 1,2 . Similarly, the more lipophilic opioids such as methadone and fentanyl are able to cross the meninges quite rapidly, resulting in a short onset of action 15 .…”

. Mentor. Responsible for intellectual and scientific content of the study; statistical analysis; critical revision. ABSTRACT PURPOSE:To compare the cardiopulmonary effects and the quality of anesthesia of the extradural lidocaine in combination with fentanyl or morphine in bitches undergoing ovariohysterectomy. METHODS:Sixteen female dogs, were sedated with intramuscular acepromazine (0.05mg kg -1 ), followed by anesthetic induction with intravenous propofol (4mg kg -1 ), to perform the lumbosacral puncture. The animals were randomly assigned to two treatments:T-F (n=8) extradural administration of fentanyl (5µg kg -1 ), T-M (n=8) extradural administration of methadone (0.3mg kg -1 ). In both treatment groups, opioids were combined with lidocaine, in order to make up a final volume of 0.4mL kg -1 . Heart rate (HR), respiratory rate (RR), systolic arterial blood pressure (SABP), intra-operative anesthetic supplementation, blood gases and adverse effects were investigated.RESULTS: HR, arterial pH and blood gases did not differ between treatments at any time point. RR and SABP decreased after epidural anesthesia, but the values were in terms of the physiological range of dogs. Intra-operative anesthetic supplementation was required in 50% and 62.5% of the fentanyl and methadone treated dogs, respectively. CONCLUSION:The extradural lidocaine in combination with fentanyl or morphine allowed cardiopulmonary stability, however sufficient sensitive blockade was not provided in 100% of the dogs.

PURPOSE: To compare the postoperative analgesic effects of the extradural tramadol or morphine in female dogs undergoing ovariohysterectomy. METHODS: Sixteen female dogs were randomly assigned to two groups of eight animals each and received morphine (0.1mg kg-1 M group) or tramadol (2mg kg-1 T group). The pre-anesthetic medication was intravenously (iv) acepromazine (0.05mg kg-1). Anesthesia was induced with propofol (4mg kg-1iv) and maintained with isoflurane. The degree of analgesia was evaluated using a numerical rating scale that included physiologic and behavior variables. Dogs were scored at one, three, six and 12 hours after surgery by one blinded observer. Dogs were treated with morphine (0.5mg kg-1) if their scores were >6. Serum cortisol was measured before the pre-anesthetic medication was administered (basal), at the time of the ovarian pedicle clamping (T0), and at 1 (T1), 6 (T6) and 12 (T12) hours postoperative. RESULTS: The pain score did not differ between morphine and tramadol treatments. Rescue analgesia was administered to one dog in the T treatment group. Serum cortisol did not differ between treatments. CONCLUSION: The extradural administration of morphine or tramadol is a safe and effective method of inducing analgesia in female dogs undergoing ovariohyterectomy.
