“…According to Silva et al (2008) and Jacobina (2009), the cranial progression of local anesthetic promotes sympathetic block, resulting in vasodilation of the arterioles and subsequent hypothermia. According to Ishiy (2001) Skarda & Tranquilli (2007), Cassu et al (2008), and Tamanho et al (2009), the epidural anesthesia leads to redistribution of heat through the body and to interference in central and peripheral thermoregulation, inducing the occurrence of hypothermia. In addition, induction with propofol causes hypotension resulting from arterial and venous vasodilation, which potentiates the redistribution of body heat (Branson, 2013).…”

“…Epidural anesthesia is a simple, safe, effective, and lowcost technique characterized by the administration of drugs with analgesic properties in the epidural space aiming at promoting anesthesia and analgesia (Otero, 2005;Skarda & Tranquilli, 2007;Cassu et al, 2008;Tamanho et al, 2009).…”

“…When using the dose in 1.0 mL for each 4.5 kg of weight, analgesia and anesthesia are delivered to the first lumbar vertebra in the dog, blocking the perineum, pelvic limbs, and caudal abdomen (Campello et al, 1977;Jones 2001;Otero, 2005;Skarda & Tranquilli, 2007;Andrade, 2009;Tamanho et al, 2009). Otero (2005) suggests the use of 1.5 mL for each 10 cm of occipito-coccygeal distance to promote a satisfactory cranial block to the 5th thoracic vertebra, without compromising the respiratory dynamics.…”

RESUMOThe effects of volume on lumbosacral epidural block in dogs were evaluated using two different doses of 2% lidocaine. Ten adult dogs, without defined breed, were subjected to two different anesthetic protocols. In the first, the local anesthetic was calculated based on the body weight (GP), wherein 1.0 mL of local anesthetic was used for each 3.5 kg; in the second protocol, the dose was stipulated according to the occipito-coccygeal (DG) distance with 1.5mL of local anesthetic for every 10 cm of distance. The available time, recovery period, extent of block, and rectal temperature were measured. After the analysis of the results, it was possible to verify that there was an increase in the time in GD when compared with GP, due to the greater volume administered in that group. The recovery period remained similar in both groups, despite the use of different doses. Regarding the extent of blockade, there was an increase in GD in relation to GP due to the increase of the local anesthetic dose. On the other hand, the rectal temperature presented a difference between the groups, remaining lower and below the reference values for the species in GD compared with GP at all moments analyzed, possibly due to a sympathetic action triggered by the cranial extension of the epidural block. It could be concluded that when a longer time and a more cranial blockade of epidural anesthesia are desired, the anesthesia volume should be based on the occipito-coccygeal distance, however, observing the rectal temperature.Key words: lidocaine; volume; timing; recovery time; rectal temperature. Gisele Martins de Paula Estudo comparativo da anestesia epidural em cães por peso ou distância ocipto-coccígeaAvaliaram-se os efeitos do volume no bloqueio epidural lombossacro em cães utilizando-se duas doses diferentes de lidocaína a 2%. Foram utilizados dez cães adultos, SRD submetidos: No primeiro protocolo, o anestésico local foi calculado com base no peso corporal (GP) e no segundo protocolo a dose foi estipulada de acordo com a distância ocipto-coccígea (GD). Sendo os mesmos animais submetidos aos dois protocolos anestésicos, com intervalo de dez dias. Mensurou-se o tempo hábil, o período de recuperação, a extensão do bloqueio e a temperatura retal. Após a análise dos resultados foi possível constatar que houve acréscimo no tempo hábil em GD quando comparado a GP, devido ao maior volume administrado em tal grupo. O período de recuperação se manteve semelhante em ambos os grupos, apesar do uso de doses diferentes. Com relação à extensão do bloqueio, houve um aumento em GD quando comparado a GP devido ao aumento da dose de anestésico local. Já a temperatura retal apresentou diferença entre os grupos, mantendose menor e abaixo dos valores de referência para a espécie, em GD na comparação com GP em todos os momentos analisados possivelmente devido a uma ação simpática desencadeada pela extensão cranial do bloqueio epidural. Pode se concluir que quando se dejesa um maior tempo hábil e um bloqueio mais cranial de anestesia epidural...

“…Morphine administered extradurally in combination with lidocaine provided safe and satisfactory anesthesia for performing OHE in 100% of the dogs, so that general supplemental anesthesia was not required 9 . Similar results were showed with extradural butorphanol plus lidocaine for dogs undergoing OHE 7 .…”

. 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.
