Great value has been given to anesthesia since its discovery. A fact that has revolutionized several medical areas, including Veterinary Medicine. In order for anesthesia to be conducted adequately and satisfactorily, a prior evaluation of the patient to be submitted to surgery, such as a review of the clinical history, physical examination, complementary exams and, finally, a risk assessment and physical condition is required. It is important to direct the patient to an anesthetic protocol appropriate to their state of health, as well as to predict the prognosis of the same. This classification of risk and physical status, adopted by the American Society of Anesthesiologists (ASA), is accepted and used worldwide by human and veterinary doctors, and is widely discussed in scientific works involving anesthesiology, justifying its great importance, being the objective of this review.Keywords: Anesthesia, surgery, canine, feline Estado físico y riesgo anestésico en perros y gatos: Revisión RESUMEN.

RESUMOA classificação de estado físico ASA (Sociedade Americana de Anestesiologistas) é uma ferramenta importante para a avaliação pré-anestésica do paciente. Assim, é utilizada em diversos estudos por possuir estreita relação com a morbidade e a mortalidade anestésica. Realizou-se tal classificação em 243 pacientes caninos submetidos a procedimentos cirúrgicos em um Hospital Veterinário Universitário. Os resultados obtidos foram os seguintes: ASA I (38; 15,64%), ASA II (53; 21,81%), ASA II emergencial (E) (2; 0,82%), ASA III (78; 32,10%), ASA III E (23; 9,46%), ASA IV (11; 4,53%), ASA IV E (36; 14,81%) e ASA V (2; 0,82%). Verificou-se que a maior parte dos pacientes foram classificados como ASA III (doença sistêmica moderada), o que demonstra que, no serviço analisado, a maioria dos animais submetidos à cirurgia são portadores de enfermidades. A mortalidade foi de 2,46%, com a maioria dos óbitos ocorridos no pós-operatório e em pacientes com emergências. Concluiu-se que, no serviço analisado, os maiores riscos estão relacionados aos pacientes com categorias ASA de maior gravidade, em cirurgias emergenciais e, especialmente, no período pós-operatório. ASA III E (23; 9.46%), ASA IV (11; 4.53 %), ASA IV E (36; 14.81%), and ASA V (2; 0.82% estabilizar o paciente ou prepará-lo de forma adequada e, assim, reduzir riscos e complicações pós-operatórias (Shmon, 2007). Nessa avaliação, leva-se em consideração o estado físico atual do paciente e, uma vez detectados desequilíbrios orgânicos, estes poderão ser corrigidos (Laredo et al., 2001).

Foi realizado exame histopatológico dos fragmentos tumorais coletados, diagnosticando-o como carcinoma de células basais.Palavras chave: canino, cirurgia, neoplasia, oncologia Basal cell carcinoma in bitch: Case report ABSTRACT. Veterinary Oncology has been in great demand, especially for the increase in the longevity of dogs and the greater occurrence of neoplasias in elderly animals. A bitch, without breed, was treated for 8 years, presenting an ulcerated tumor mass in the frontal region of the head. The patient underwent preoperative exams. Then, the tumor is excised with a large margin of safety. Histopathological examination of the collected tumor fragments was performed, diagnosing it as basal cell carcinoma.Keywords: Canine, surgery, neoplasia, oncology El carcinoma de células basales en un perro: Reporte de un caso RESUMEN. La Oncología Veterinaria ha tenido mucha demanda, en especial mediante el aumento de la longevidad de los perros y la mayor incidencia de cánceres en animales más viejos. Fue atendida una hembra canina mestiza, edad de ocho años, presentando una masa tumoral ulcerada en la región frontal de la cabeza. Esta fue sometida a exámenes preoperatorios. A continuación, la resección del tumor con amplia margen de seguridad. De los fragmentos del tumor colectados se realizó examen histopatológico, diagnosticándolo como carcinoma de células basales.Palabras clave: Cáncer, canino, cirugía, cáncer, oncología IntroduçãoA Oncologia Veterinária vem despontando nos últimos anos, isso se deve, entre muitos fatores, pelo aumento da longevidade de cães, maiores cuidados e promoção de bem-estar por parte dos tutores (Bagliotti et al., 2015) e pelo fato do câncer ser uma das principais causas de óbito (Bentubo et al., 2007). As neoplasias ocorrem independentes da idade, mas como se espera, tem maior índice nos cães idosos (Borges et al., 2016).Não diferente do humano, esta doença causa grande impacto psicológico em seus tutores, por associarem o câncer ao sofrimento, dor e óbito (Costa et al., 2016), o que pode gerar medo ou
The objective of this report was to record surgical procedures performed in 241 dogs in a teaching veterinary hospital. There were 40 elective surgical procedures (16.6%) and 201 therapeutic surgical procedures (83.4%). The most frequent procedure was ovariohysterectomy (OH), 65% (26/40) and 24.38% (49/201), respectively, for elective and therapeutic surgical procedures. Among therapeutic surgical procedures were registered fracture reduction (16.91%, 34/201), mastectomies (13.93%, 28/201), drainage of the otohematoma (12.94%; 26/201) and ophthalmic surgical procedures (5.47%, 11/201). The high percentage of therapeutic surgical procedures conducted demonstrates the complexity of the cases attended daily in a teaching veterinary hospital.
Background: To reduce morbidity and mortality associated with anesthetic procedures in cats, it is important to carry out a thorough pre-anesthetic evaluation. The surgical risk depends on several factors related to the patient, the surgical procedure, and the anesthetic used. Evaluation of perioperative mortality and the identification of the main factors of death reduce mortality rates. This research was conducted to evaluate and obtain the classification of physical status and anesthetic risk in cats submitted for surgical procedures.Materials, Methods & Results: Ninety-two cats were classified into anesthetic categories according to the American Society of Anesthesiologists (ASA) classification. The group consisted of 62 females (67.39%) and 30 males (32.61%). In the ASA classification, the emergency qualifier was added, resulting in 52.17% (48/92) of the total number of surgeries being considered as emergencies. The ASA I patients constituted the majority of the study sample (33.69%, 31/92). There were no deaths among ASA I patients. The ASA II patients represented 20.65% (19/92), with surgeries divided into non-emergency (42.10%, 8/19) and emergency (57.89%, 11/19). All ASA II patients had mild localized infections, and there were no deaths. ASA III patients constituted 28.26% (26/92) of the study sample and had moderate systemic alterations. Surgeries in this group were also classified as emergency (24/26, 92.30%) or non-emergency (2/26, 7.69%). There was one postoperative death in this group. The ASA IV patients represented 17.39% (16/92) of the study sample. The emergency surgeries (81.25%, 13/16) had a greater percentage than the elective surgeries. In this group, two deaths occurring in the immediate postoperative period. The overall mortality for the entire study sample was 3.26% (3/92).Discussion: The majority of the surgeries were emergency surgeries, indicating that, in the feline specie, in the service analyzed, most owners seek medical treatment under these conditions. In these situations, there is a need for rapid intervention since there is a high probability of immediate adverse consequences with the added risk of death. The results obtained from the ASA I patients are expected in animals of this classification, whose prognosis is considered excellent. The patients ASA II included six patients with obstructive lower urinary tract disease (OLUTD) that progressed to ASA III and IV, proving that patients with OLUTD need urgent attention. Some animals ASA III entered this classification because they presented anemia. These clinical sign was considered of great importance since the reduction of circulating red blood cells reduces tissue oxygenation, thereby increasing surgical risk due to hypovolemic shock. The one death in the ASA III group occurred in the postoperative period, and necropsy indicated septicemia, which has a high mortality rate. ASA IV patients were placed in this category due to serious diseases such as neoplasms accompanied by secondary infection, urolithiasis with post-renal azotemia, OLUTD with azotemia, and pyometra. All deaths in the ASA IV group occurred in the immediate postoperative period. Recent data suggest that the postoperative period is the period associated with the highest risk of mortality. This may have been a reason for these deaths, along with the fact that all these patients were emergency patients, because in such procedures, the risk of death is much higher in patients undergoing emergency surgeries than in those undergoing elective surgeries. Starting by the patients classified as ASA grade III, the mortality was higher, as well as in cases of emergency. The overall mortality rate was high, with a higher risk during the immediate postoperative period. It is recommended that felines be carefully monitored postoperatively to reduce mortality rates.
