RESUMO

Background: The Choloepus didactylus is characterized by having 2 fingers on the forelimbs and 3 on the hind limbs, being found more frequently in northern South America, in countries such as Venezuela, Guyana, Ecuador, Peru, and Brazil. In Brazil, deforestation of the Amazon rainforest has threatened the survival of C. didactylus. In addition, these animals can be affected by several diseases, being those of the musculoskeletal system with limited reports. Thus, the present report aimed to describe the treatment and evolution of an open fracture of the femur in a free-living Choloepus didactylus, which after rehabilitation was released back to the wild. Case: A free-living female two-toed sloth (Choloepus didactylus), weighing 7.0 kg, was found in Manaus city and referred to the Wild Animal Treatment Center (CETAS - IBAMA-AM) located in Amazonas, Brazil, after initial treatment and osteosynthesis in a private clinic (CVMinasPet). According to history, the animal had suffered electrocution 30 days ago and, as a result, had an extensive wound that resulted in the exposure of the knee joint, distal fracture of the femur, and areas of necrosis in the right pelvic limb. After cleansing of the area and removal of necrotic tissues, the fracture was stabilized with the cross-pinning technique (2 Steinmann pins). Then, the stifle joint was stabilized with external skeletal fixation (Type 1b, unilateral biplanar). The external fixator and cross-pins were removed 2 months after the surgical procedure, being observed bone healing. Next, the animal underwent physical rehabilitation for 30 days. After the rehabilitation period, a microchip and a radio collar were applied, and the sloth was released back to the wild. Discussion: Electrocution has been one of the causes of wildlife rescue, with consequences varying depending on the degree of the burn. Generally, the burn is most severe at the entry and exit sites. Since suspensory quadrupedal locomotion requires that sloths have specialized hands and feet to connect with the supports, probably the animal of the current report touched the right pelvic limb on a high-tension pole. The cross-pinning technique combined with the external fixator was used because the animal had an exposed Salter-Harris type I fracture with soft tissue loss. The younger the animal presents physeal fractures, the greater is the chance of developing growth abnormalities due to growth plate closure caused by fracture type or immobilization method. Since the sloth was a free-living animal, the age was unknown. However, pelvic limb length discrepancy was not observed after removing the implants. Culture and antimicrobial susceptibility test were not done and may be considered a limitation of this report. However, the application of ceftriaxone was adequate to control the infection, since the animal did not show signs of infection or draining sinus tracts. Ceftriaxone is a third-generation antibiotic that can be used in chronic osteomyelitis. In addition, the animal in the present report showed good adaptation to captive conditions that contributed to the clinical management. The longevity of the sloth in captivity can reach more than 30 years, but the goal is always to return the animal to nature after the treatment. Surgical treatment of the fracture and physical therapy after implant removal allowed this action in the current report, confirmed by monitoring with the radio collar.

RESUMO

Objetivou-se avaliar a influência da insensibilização inadequada durante o abate de suínos na cor, pH e perdas de água da carne. Após eletrocussão dos animais em um abatedouro-frigorífico sob SIF da região da Zona da Mata, Minas Gerais, parâmetros de insensibilização foram avaliados em 3.347 suínos abatidos. Os parâmetros avaliados foram ausência de reflexos palpebrais, reflexo de orelhas, gritos, pedalagem nos membros anteriores e respiração arrítmica. Após o completo abate e 16 horas de estocagem das carcaças em câmara fria a 2°C, fragmentos transversais do músculo Longissimus dorsi foram obtidos de animais selecionados de forma randomizada e insensibilizados de forma adequada (n=12) e inadequada (n=12). As amostras de carne foram avaliadas quanto ao pH, Capacidade de Retenção de Água (CRA). Do total de 3.347 suínos abatidos, 272 (8,13%) apresentaram pelo menos algum sinal de insensibilização inadequada. Observou-se que as 24 amostras de carne tiveram pH médio de 6,06, perda média de 24,74% de água e escore médio de 3,64 na escala de cor avaliada. O pH médio da carne obtida de animais inadequadamente insensibilizados (6,11) foi maior (p<0,05) que o pH médio de animais adequadamente insensibilizados (6,01). Quanto menor o pH da carne menor era o seu escore de cor e CRA (p<0,05). Portanto, a carne obtida de suínos mal insensibilizados possui maior pH, o que resulta em carne mais escura e com baixa CRA.(AU)

The objective of study was to evaluate the influence of inadequate sttuning during the swine slaughter in color, pH, and water loss of meat. After electric sttuning of animals in a slaugtherhouse under SIF of the Zona da Mata region, Minas Gerais, stunning parameters were evaluated in 3,347 slaughtered swines. The parameters evaluated were the absence of eyelid reflexes, ear reflexes, screams, pedaling in the forelimbs and arrhythmic breathing. After the full 16 hours of slaughter and storage of carcases in a cold chamber at 2°C, transverse fragments Longissimus dorsi muscle were obtained from randomly selected animals and properly (n=12) and improperly (n=12) sttuninged animals. The meat samples were evaluated for pH, Water Holding Capacity (WHC). Of the 3,347 slaughtered swines, 272 (8.13%) showed at least some sign of inadequate sttuning. It was observed that the 24 meat samples had mean pH of 6.06, mean loss water of 24.74% and mean score of 3.64 evaluated in color scale. The mean pH of meat obtained from animals improperly sttuninged (6.11) was greater (p<0.05) than the mean pH of animal properly sttuninged (6.01). The lower pH of meat causes lower color score and WHC (p<0.05). Therefore, the meat obtained from improperly sttuninged swine has a higher pH, which results in darker meat and low WHC.(AU)

RESUMO

Resumen Introducción: son pocos los datos documentados sobre los resultados de la reanimación cardiopulmonar en el paro cardiorrespiratorio extrahospitalario por causa de electrocución. El paro cardiorrespiratorio se produce cuando una descarga eléctrica interrumpe de forma abrupta la actividad eléctrica normal del corazón, lo que genera una electrocución y una alteración en los movimientos cardiacos y, por consiguiente, bombeo anormal de sangre y oxígeno a los tejidos. Ello constituye una emergencia clínica que puede ocasionar nefastas consecuencias de no tomarse medidas enérgicas e inmediatas. Presentación del caso: hombre con paro cardiorrespiratorio producido por electrocución y manejado en un ámbito extra-hospitalario, quien respondió con éxito a las maniobras aplicadas. Personal técnico y de salud iniciaron precozmente la reanimación cardiopulmonar y luego fue reforzada por personal médico, que aplicó desflbrilación en dos ocasiones con desflbrilador externo automático (DEA). Con ello se logró recuperar los signos vitales del paciente y trasladarlo a un centro asistencial para continuar su manejo intrahospitalario. Conclusión: la realización de una reanimación precoz y la desfibrilación de pacientes electrocutados, así como las medidas encaminadas a la protección del cerebro, son la norma prioritaria en la asistencia pre-hospitalaria de estos pacientes, quienes son potencialmente recuperables. Por tal razón, es importante que la comunidad, en general, esté preparada y que el personal de salud se reentrene en soporte vital básico, que incluye el manejo del DEA para dar oportunidad de sobrevivir a personas que sufran un paro cardiorrespiratorio extrahospitalario.

Abstract Introduction: There are few the documented data about the cardiopulmonary resuscitation results in the cardiorespiratory arrest extra-hospital due to the electrocution. The cardiorespiratory arrest occurs when the heart's normal electrical activity is abruptly interrupted by electric shocks generated by electrocution, causing the disturbance in the cardiac movements and, consequently, abnormal pumping of blood and oxygen to the tissues. The cardiorespiratory arrest due to electrocution is one clinic emergency that can cause disastrous consequences, if energetic measures are not taken immediately. Case presentation: A man with cardiorespiratory arrest produced by electrocution and managed in an extra-hospital area, who responded successfully to the maneuvers applied. The cardiopulmonary resus-citation maneuvers were precociously started by the health technical staff; next, reinforced by medical it, applying the defibrillation on two occasions, with external automatic defibrillator (AED), recovering the patient's vital signs and allowing his transfer to a healthcare center to continue in-hospital management. Conclusion: The performing of early resuscitation and defibrillation of electrocuted patients, as well as the measures aimed at protecting the brain, are the priority rules in the pre-hospital scene of these patients, who are potentially recoverable. For this reason, it is important that the community, in general, be ready, and the health staff gets trained in basic vital support that includes the management of AED to give the opportunity of surviving to people that suffer a cardiorespiratory arrest.
