Background: The use of peripheral intravenous devices can lead to infections and increase the length of hospital care worldwide in humans and animals. Antisepsis is indicated in several ambulatory and surgical procedures. Chlorhexidine is an antiseptic widely used in veterinary clinical practice. Nanoparticle solutions have been studied to improve antimicrobial effect. Therefore, we aimed to evaluate the antiseptic effect of chlorhexidine nanoemulsion at 0,25% (NM-Cl) in cat skin and to compare it with the chlorhexidine commercial solution at 2.0% (CS-Cl). After a wide trichotomy of the thoracic limbs, the skin antisepsis was performed with NM-Cl or CS-Cl and a catheter was inserted at the cephalic vein. Cutaneous microbiota swab samples (CMSS) were obtained before antisepsis (Tpre), immediately after antisepsis (Tpost), and four, eight, and 24 hours after antisepsis. The samples collected were immediately inoculated in blood agar plates and incubated at 35±2ºC in aerobiosis. The manual counting of the colony-forming unit (CFU) was performed 24 hours after inoculation. Kruskal–Wallis and Mann–Whitney tests were used between groups and inside the same group, at different sample times. Result: The NM-Cl and CS-Cl groups showed a reduction in the CFU between the Tpre and Tpost in all animals (p<0.001). Both formulations presented an antiseptic effect 24 hours after antisepsis (p<0.05), and there was no difference between formulations at the different times (p<0.05). Nonetheless, the NM-Cl carried a lowers concentration of chlorhexidine than CS-Cl. Conclusion: The results showed that NM-Cl presents effective antiseptic action and a prolonged residual effect in the cat venipuncture antisepsis. Studies have been carried out to investigate the NM-Cl in veterinary routine.
Considerando a importância do cuidado com a saúde mental dos estudantes e médicos veterinários, o objetivo do estudo foi avaliar a percepção dos médicos veterinários sobre o preparo obtido sobre a terminalidade da vida do paciente durante a graduação de medicina veterinária e programas de residência. Médicos veterinários matriculados em programas de residência em área profissional da saúde no estado do Rio Grande do Sul (RS), Brasil, foram convidados a responder um questionário semiestruturado. Obteve-se a participação de 31,3% (N=42) dos profissionais, os quais representam um grupo de risco para o desenvolvimento de esgotamento saúde mental considerando o sexo, idade e tempo de formação. Os treinamentos formais relativos ao gerenciamenteo de emoções quanto óbito do paciente e prática da eutanásia não foram abordados durante a graduação de mais de dois terços dos respondentes, fato que preocupantemente também é observado durante a pós-graduação. Somente 11,9% (N=2) relatam ter recebido treinamento durante a graduação para comunicar o óbito ao cliente e 9,5% (N=1) durante a residência. O estudo evidenciou que os médicos veterinários atuantes nos programas de residência do Rio Grande do Sul, Brasil, não tiveram preparo durante a graduação nem durante a residência para lidar com o óbito dos paciente. . A inclusão desse treinamento formação do médico veterinário por meio de disciplinas específicas podem auxiliar na formação de profissionais mais preparados, minimizando o efeito psicológico atrelado.
Background: Trauma is the main cause of spinal fractures and dislocations in humans and large animals. Clinical signs present with acute onset and vary according to the location and severity of the spinal cord injury. The treatment of fractures in large animals depends on economic value, cost of procedures, prognosis, location and type of fracture. However, although spinal fractures in large animals are not uncommon, the literature about their clinical aspects and treatment is scanty. Therefore, the purpose of this report is to describe a surgical stabilization of atlantoaxial subluxation, fracture of the third cervical vertebra and C2-C3 subluxation.Case: An approximately 2-year-old Île-de-France sheep, weighing 101 kg, with a history of cervical trauma and non-ambulatory tetraparesis was treated at the Veterinary Hospital of the Institution (UNIPAMPA). During physical examination, the animal presented good general physical condition and heart rate, respiratory rate and temperature was according to physiological parameters for the species. The animal remained in lateral decubitus, with minimal head and limb movements, and exhibited deep pain sensitivity. Clinical treatment with dexamethasone, limb physiotherapy and change in lateral decubitus position were employed, but failed to improve the animal’s condition. After five days of unresponsive to clinical treatment, the patient was referred to the neurology department, where it underwent neurological examination and radiographic examination of the cervical region was performed under general anesthesia. The radiographic examination revealed atlantoaxial subluxation, by displacement of the odontoid process into the vertebral canal, fracture of the third cervical vertebra and C2-C3 vertebral subluxation. The surgical planning aimed cervical vertebral instability repair using atlantoaxial arthrodesis associated the stabilization of C1-C2 and C2-C3 vertebrae with Schanz pins and bone cement, due facility and versatility this association. The postoperative radiographic examination showed incomplete insertion of the Schanz pin into the left Atlas wing and a cervical collar was recommended. The clinical evaluation was performed daily, and after 23 days of surgery the animal could crawl in lateral decubitus besides assisted walking ability. However, the animal died 36 days after surgery due to severe dyspnea. A necropsy revealed pulmonary edema and hepatic lipidosis, besides hepatic septic thrombus. Moreover, the vertebral canal of C1-C2 and C2-C3 segments stayed realigned and stabilized, without spinal cord injury and trachea compression.Discussion: Non-ambulatory tetraparesis, and minimal head and limb movements confirm severe spinal cord injury. The failure of clinical treatment, craniocervical instability in C1-C2 and C2-C3 and the high economic and genetic value of patients was definite for the surgical indication, besides reserved prognosis. The surgical treatment aim is recovery motor function from spinal cord decompression, vertebral canal realignment and the stabilization of vertebral instability. The cervical collar was placed on the patient after the surgery was intended to prevent rotation of the atlantoaxial joint, aiding vertebral stability. It is believed that the recovery of large animals with spinal cord injuries like in this case report is slower due to their heavy weight and the difficulty in managing such patients. This case report confirms that the techniques employed here achieved the proposed objectives of spinal canal alignment and spinal stabilization, showing improvement of clinical signs and recovery of the animal’s limb and neck movements.
