RESUMO

Os bloqueios locorregionais são considerados padrão-ouro para a analgesia perioperatória. Sendo assim, este trabalho apresenta o efeito da associação do bloqueio do plano transverso do abdome com o bloqueio do plano serrátil em um felino de 11 anos, fêmea, que foi submetido à mastectomia unilateral. Foi utilizada a metadona 0,3 mg/kg via intramuscular (IM) na medicação pré-anestésica e propofol dose-efeito via intravenosa (IV) para indução, enquanto a manutenção foi feita com isoflurano. O TAP Block e o SP-Block foram realizados unilateralmente utilizando a associação de bupivacaína 0,3mL/kg, em cada ponto, diluída a 0,25% com solução fisiológica. A frequência cardíaca (FC), a frequência respiratória (f), a pressão arterial não invasiva (Método Doppler), a temperatura esofágica (oC), a saturação de oxigênio (SpO2), a capnografia (EtCO2) e o eletrocardiograma foram monitorados continuamente e registrados a cada dez minutos. A paciente foi monitorada por cinco horas, após a extubação, quanto à dor, sendo utilizada, para isso, a Escala Multidimensional de Dor Aguda (UNESP-Botucatu). A recuperação anestésica da paciente foi rápida e sem complicações. Durante a avaliação de dor, o animal apresentou escore zero, não manifestando qualquer desconforto pós-operatório. A associação das técnicas foi eficaz no bloqueio anestésico das paredes torácica e abdominal, sugerindo a inclusão destas nos protocolos de analgesia multimodal para esse tipo de cirurgia.

Locoregional blocks are considered the gold standard for perioperative analgesia. Thus, this paper presents the effect of the association of transverse abdominal plane block with serratus plane block in an 11-year-old female feline submitted to unilateral mastectomy. Methadone 0.3 mg/kg via intramuscular (IM) was used as pre anesthetic medication and dose-effect propofol via intravenous (IV) was used for induction, while the maintenance was done with isofluorane. TAP Block and SP-Block were performed unilaterally using an association of Bupivacaine 0.3 ml/kg at each point, diluted to 0.25% with saline solution. Heart rate (HR), respiratory rate (f), non-invasive blood pressure (Doppler method), esophageal temperature (oC), oxygen saturation (SpO2), capnography (EtCO2), and electrocardiogram were monitored continuously and recorded every 10 minutes. The patient was monitored for pain during five hours after extubation using the Multidimensional Scale of UNESP-Botucatu. The anesthetic recovery of the patient was fast and without complications. During pain assessment, the animal presented a score of zero and did not present any postoperative discomfort. The association of techniques was effective in the anesthetic blockade of the thoracic and abdominal walls, suggesting their inclusion in multimodal analgesia protocols for this type of surgery.

RESUMO

Background: Mammary tumors, for which mastectomy is the main treatment, are the most common neoplasms in bitches. Mastectomy is painful and, in order to reduce the pain stimulus in the transoperative period, tumescent local anesthesia is associated with general inhalation anesthesia. However, despite the numerous benefits of tumescence, intraoperative hypothermia is the most common complication. In Medicine, especially in plastic and dermatological surgery, it is common to use a heated tumescence solution to prevent intraoperative hypothermia; however, in Veterinary medicine, no previous study has examined the advantages and disadvantages of using heated tumescence solution. Thus, this study aimed to investigate the transanesthetic cardiorespiratory effects of heated tumescence solution in bitches submitted to radical unilateral mastectomy. Materials, Methods & Results: Eight animals were treated with 0.1% lidocaine solution, warmed to 37-42°C, using a Kleins cannula for administration. Chlorpromazine (0.3 mg/kg) and meperidine (3 mg/kg) were used as pre-anesthetic medication intramuscularly, and induction was performed with intravenous propofol and maintenance with isoflurane. The data collection times were as follows: 15 min after starting isoflurane administration (M1), 5 min after tumescence (M2), after beginning of surgical incision (M3), during breast pullout (M4), after clamping of the superficial caudal epigastric vein, and artery (M5), after the beginning of the approximation of the subcutaneous tissue (M6), after the beginning of the intradermal suture (M7), and at the end of the surgical procedure (Mfinal).

RESUMO

Background: Mastitis is an inflammation of the mammary gland or udder, regardless of its origin, severity, or evolution. Bilateral total mastectomy is indicated in cases of chronic suppurative mastitis, gangrenous mastitis, udder neoplasm or hyperplasia. For mastectomy, the supine position is recommended and, as it is a long-term procedure, general anesthesia was chosen together with the tumescence technique with the objective of transanesthetic and postoperative analgesia. The present report aims to report the general anesthesia protocol used for 2 goats submitted to bilateral total mastectomy associated with a locoregional block by tumescence, a technique not described in the goat species. Cases: Two female goats, mixed breed, approximately 3 years old, were admitted to the Hospital Veterinário de Grandes Animais (HVGA) of the Universidade Federal Rural do Rio de Janeiro (UFRRJ), with a history of recurrent mastitis. There was an increase in udder volume and the presence of purulent secretion during milking. One of the animals had given birth about 20 days ago. Surgical treatment through bilateral total mastectomy was recommended for both animals, as they did not present a satisfactory response to antimicrobial therapy, excessive enlargement and functional loss of the mammary system. For the procedure, food fasting for 48 h and water fasting for 24 h was established. The anesthetic protocols used consisted of previous sedation with xylazine1 [Xilazin® - 0.05 mg/kg, IM] anesthetic induction with ketamine2 [Ketalex® - 10 mg/kg, IV] and midazolam3 [Dormire® - 0.1 mg/kg, IV]. Orotracheal intubation and connection to the anesthetic circuit were performed for maintenance through inhalation anesthesia with isoflurane4 (Forane®) and oxygen therapy. Then, in bottle of lactated ringer's solution5 [Linhamax® - 500 mL], lidocaine 2%6 without vasoconstrictor [Lidovet® - 40 mL] and adrenaline7 [Adren® - 25 mg/mL, 0.5 mL] were added, 10 mL/kg of the solution were injected into the subcutaneous tissue of the region of the mammary chains utilizing a Klein cannula after local antisepsis. After the administration of the tumescent solution, it was observed that the area involved is presented with the formation of a gel and there is minimal bleeding, compared to the conventional technique. The animals were monitored for the degree of analgesia, recording vital signs every 15 min at the end of the surgery, dipyrone9 [D-500® - 25 mg/kg, IV], morphine7 [Sulfato de Morfina® - 0.1 mg/kg, SC], and meloxicam10 [Maxican® 0.5 mg/kg, IM, 3 consecutive days] for postoperative analgesia. Additionally, tetanus serum1 [Vencosat® - 50,000 IU, single dose] and of oxytetracycline¹ [Oxitetraciclina LA® - 10 mg/kg, IM, 5 applications on alternate days)]. In the following 24 h, no signs of pain were observed on palpation of the surgical wound in the animals, but goat 1 was apathetic and inappetent, with improvement in the clinical picture only 48 h after surgery. Discussion: The choice of the surgical procedure resulted in an improvement in the clinical conditions of the animals and the anesthetic protocol using inhalation anesthesia and locoregional block (tumescence) proved to be efficient to perform in goats, contributing to transanesthetic and postoperative analgesia, being easily applied to ruminants that need surgical interventions in the region of mammary chains.

RESUMO

Background: The frequency of oncological diseases in companion animals has increased in recent years, mainly due tothe longer longevity of dogs. The neoplasms are not only open by the presence of the tumor and its location, but also byparaneoplastic syndromes, which are disorders that occur due to the production of substances by the tumor that cause.In addition to causing local changes and damages, oncological diseases may also result in injuries at distant sites, suchas paraneoplastic syndromes, which, if untreated, may result in death of animals. The present study aimed to investigatewhether female dogs with mammary tumors demonstrate electrocardiographic changes, and if so, to investigate whetherthese cease after removal of the tumor, and to relate the type of tumor with the occurrence of arrhythmias.Materials, Methods & Results: Eighteen female dogs, aged between 4 and 14 years, underwent electrocardiogram 24 hprior to undergoing a total unilateral mastectomy. After removal of the tumor, electrocardiograms were again performed 24(M24), 48 (M48), and 72 (M72), as well as 14 days (M14d) after surgery. Histological analysis of the neoplasms showedthat 55% of the tumors were benign, with predominance of adenoma (38%), and 45% were malignant, with predominanceof adenocarcinoma (22%). The following rhythms and arrhythmias were observed: normal sinus rhythm (37.2%), sinusarrhythmia (62.8%), wandering pacemaker (26%), 1st degree atrioventricular block (AVB; 5%), premature ventricularcomplex (PVC; 10%), and T-wave > 25% of R-wave (25%); more than one change could occur simultaneously. Out of theevaluated electrocardiographic parameters, a significant difference was observed in the QT interval between the followingtimepoints: M24 (204 ± 18), M48 (204 ± 22), and M72 (203 ± 23), as well as Mbasal (192 ± 15) and M14d (178 ± 43).Discussion: Regarding the observed rhythms, arrhythmias, and changes, respiratory sinus arrhythmia was the normal predominant...

RESUMO

Objetivou-se correlacionar a necessidade de resgate analgésico pós-operatório por meio das escalas analógica visual (EVA), de Glasgow, Colorado e Melbourne, por meio de um avaliador experiente (AE) e outro não experiente (ANE), em cadelas submetidas à mastectomia unilateral total. Foram utilizadas 24 cadelas, hígidas, internadas 24 horas antes do procedimento cirúrgico, para avaliação do seu comportamento, com o auxílio das escalas descritas acima no momento basal (M0). Foram pré-medicadas com acepromazina e morfina (0,02 e 0,5mg/kg) e induzidas à anestesia geral com propofol (4mg/kg), mantidas em plano anestésico com CAM de isoflurano 1%. A manutenção analgésica transoperatória foi realizada com cetamina e fentanil (10µg/kg/min e 10µg/kg/h). As demais avaliações ocorreram em uma, duas, quatro, seis, oito, 12 e 24 horas de pós-operatório, sendo os resgates realizados com morfina (0,5mg/kg), pela via intramuscular, quando fosse observada uma pontuação maior ou igual a 50, seis, dois e nove pontos, respectivamente, para as escalas descritas, quando observada pelo AE e quando ao menos duas das escalas demonstrassem esses valores. Houve aumento dos escores de dor do M1 ao M12 para o AE e para o ANE para a EVA. Na análise de Colorado, maiores pontuações de dor ocorreram em relação ao M0 entre o M2 e o M8 para o AE e do M1 ao M12 para o ANE. Na análise de Glasgow, maiores escores foram detectados entre o M1 e o M12 para o AE e do M1 ao M24 para o ANE. E para a de Melbourne, maiores valores foram observados do M1 e do M24 para o AE e o ANE. A melhor correlação entre as escalas foi de 0,775 entre Glasgow e Colorado e entre os avaliadores de 0,925 para a Glasgow. Conclui-se que a escala de Glasgow apresentou-se mais sensível para detectar resgates analgésicos em cadelas submetidas à mastectomia total unilateral, que a inexperiência do avaliador não compromete a qualidade das avaliações de dor e sugere-se reduzir a pontuação da EVA e Melbourne para aumentar a sua capacidade em detectar resgates analgésicos pós-operatórios.(AU)

The objective was to relate the need for analgesic postoperative recovery through Visual Analogue Scale (VAS), Glasgow, Colorado and Melbourne, by an experienced assessor (AE) and other non-experienced ones (ANE), in bitches undergoing total unilateral mastectomy. Otherwise healthy bitches, a total of 24, were admitted 24 hours before the surgical procedure for assessment of behavior with the help of the above scales to determine the baseline (M0) moment. They were pre-medicated with morphine and acepromazine (0,02 and 0,5 mg/kg) and general anesthesia was induced with propofol (4 mg/kg) and maintained with isoflurane at 1% MAC. The analgesic during surgery was maintained with ketamine and fentanyl (10 µg/kg/min and 10 µg/kg/h). The other evaluations were performed at 1, 2, 4, 6, 8, 12 and 24 hours postoperatively, and redemptions made with intramuscular morphine (0,5 mg/kg) when a greater than or equal score of 50, 6, 2 and 9 points was observed respectively for the described ranges, as observed by the AE and when at least two scales demonstrated these values. There was an increase of M1 to M12 pain scores for AE and the ANE for VAS. In Colorado analyses, the highest painful scores occurred in relation to M0 between M2 and M8 to the AE and M1 to M12 for ANE. In Glasgow analyses, higher scores were detected between M1 to M12 for AE and M1 to M24 for ANE. And for the Melbourne highest values were observed in M1 and M24 for AE and ANE. The best correlation between the scales was 0,775 between Glasgow and Colorado and of the evaluators of 0,925 to Glasgow. The Glasgow scale was shown to be more sensitive to detect painkiller redemptions in dogs undergoing total unilateral mastectomy, the inexperience of the appraiser does not compromise the quality of painful reviews, and it is suggested to reduce the score VAS and Melbourne to increase it is ability to detect rescue postoperative analgesics.(AU)
