Bloqueio contínuo do plexo lombar via posterior bilateral com bomba de infusão descartável: relato de caso

JUSTIFICATIVA E OBJETIVOS: O número de artroplastia total de quadril (ATQ) bilateral tem aumentado a cada ano. Analgesia pós-operatória pela infusão contínua perineural com anestésico local tem se mostrado favorável quando comparada com analgesia sistêmica. O uso de bombas elastoméricas tem aumentado a satisfação do paciente quando em comparação com os modelos eletrônicos. O objetivo deste relato foi descrever um caso de analgesia contínua bilateral do plexo lombar via posterior, com infusão contínua através de bomba elastomérica, em paciente submetido à uma artroplastia bilateral de quadril. RELATO do CASO: Paciente feminina, 46 anos, 65 kg, 162 cm, com artrite reumatoide e hipertensão arterial, estado físico ASA II, escalada para ser submetida a ATQ bilateral em um único estágio. Uso de corticosteroide por 13 anos. Hemoglobina = 10,1 g.dL-1, hematócrito = 32,7%. Monitoração de rotina. Raquianestesia com 15 mg de bupivacaína 0,5% isobárica. Anestesia geral com propofol (PFS) e remifentanil e intubação sem bloqueadores neuromusculares. ATQ direita e no final, bloqueio plexo lombar com estimulador e conjunto agulha 150 mm e injeção de 20 mL bupivacaína 0,2% e passagem de cateter. ATQ esquerda e, no final, mesmo procedimento. Estudado dispersão do anestésico e contraste. Instalado bomba elastomérica com bupivacaína 0,1% (400 mL) em velocidade de 14 mL.h-1. Transferida para Unidade de Cuidados Intensivos (UCI). Vinte e quatro horas após, nova bomba com a mesma solução. Nenhum bolus durante 50 horas. Após remoção de cateter, dor controlada por via oral com cetoprofeno e dipirona. CONCLUSÕES: O bloqueio bilateral contínuo periférico com infusão de bupivacaína a 0,1% com bombas elastoméricas é um procedimento seguro e efetivo em adultos.

Aspectos médico-legais da cirurgia para hérnia inguinal

Professional responsibility is an inherent factor to the medical activity. Therefore, the adoption of a healthy conduct based on good relationship between the physician and the patient, as well as the understanding of this professional of the several aspects involved in the inguinal hernia repairs, are considered the better means to protect himself against possible litigations with its patients. This issue provides a complete evaluation of medical and legal problems related to the inguinal hernia surgery, and discusses the care that surgeon must exercise during preoperative, intraoperative and postoperative periods. That authors also comment about medical error and its conception from the point of the new Civil Code.

BLOQUEIO PERIDURAL E TERMOMETRIA CUTANEA COMO CRITERIO PARA INDICACAO CIRURGICA DE SIMPATECTOMIA LOMBAR

To find a valuable tool in achieving a good accuracy in predicting the outcome from sympathectomy, changes in limb skin temperatures (LST) before and after epidural lumbar anesthesia (ELA) and before and after lumbar sympathectomy were studied in 13 patients with thrombangiitis obliterans or arteriosclerosis obliterans. The results were compared with the clinical course and follow-up from 1 to 5 years. In seven patients there was a rise in LST after ELA and after sympathectomy, and this pattern of variation was associated with good clinical course. In three patients there was decrease in the LST after ELA and after sympathectomy and they did not do well. In two patients there was no change in temperature before or after the procedure; one of them had a good and the other a bad clinical course. The same measurements were performed in three other patients who had had a sympathectomy some years previously and the data showed that LST was lowered after ELA. It is concluded that the measurement of limb skin temperature before and after epidural lumbar anesthesia aids in determining which patients are more likely to benefit from sympathectomy.

Injeção subaracnóidea inadvertida de corticoíde em tratamento de dor crônica da coluna lombar. Relato de caso

BACKGROUND AND OBJECTIVES: Before epídural steroids were used in chronic lumbar pain, subarachnoid injection of these agents was the treatment of choice. Although still preconized by some authors, this technique may lead to severe complications with neurological sequelae. This report aimed at describing a case of accidental subarachnoid injection of steroid associated to local anesthetics during epidural puncture to treat lumbar pain. CASE REPORT: Male patient, 46 years old, followed byneuro-surgery for presenting right sciatic pain for 9 month, refractory to clinical treatment due to L 4-L 5 disk protrusion confirmed by CT scan, without neurological deficit. Epidural puncture for pain treatment was performed in L 4-L 5 with 17G needle and 10 mL solution were injected containing 4 mL of 0.25% bupivacaine, 80 mg methylprednisolone and 4 mL of 0.9% saline. Although there has not been CSF reflux, 5 minutes after injection there were sensory block in T 4 and motor block in T 6, associated to blood pressure and heart rate decrease. CONCLUSIONS: Accidental subarachnoid injections with the association of steroids for pain relief may cause adverse effects. There are several risks, varying from mild transient symptoms to nervous injuries, including spinal cord injuries. Our patient had no sequelae from the accidental subarachnoid injection, probably because it has been a single injection.

Tumor maligno da bainha de nervo periférico envolvendo raízes nervosas do terceiro segmento medular lombar em um cão

Malignant peripheral nerve sheath tumors (MPNST) involving spinal nerve roots are uncommon in dogs. A nine-year old, intact, mixed-breed dog, demonstrated clinical signs of incoordination in the pelvic limbs and micturition for approximately one week. Clinical examination revealed proprioceptive deficits and bilateral patellar hyperreflexia. During exploratory celiotomy a mass was observed adhered to the lumbar vertebral segments. Medical therapy was initiated, but neurological signs were progressive, and the owner opted for euthanasia. Gross examination showed that the mass in the abdominal cavity was attached to the lumbar segments L3 and L4, causing bone lysis in L3, but showed no tumor invasion into the spinal canal. Microscopic features were characterized by prominent proliferation of ovoid and fusiform cells with poorly defined cytoplasm arranged in interlacing bundles and concentric whorls. The cells were embedded in a delicate to moderate collagenous stroma and moderate anisokariose and high mitotic activity were noted. The immunohistochemical assay showed positive staining for GFAP, S-100 protein and vimentin, and negative staining for factor VIII, α-actin and citokeratine. The definitive diagnosis of malignant peripheral nerve sheath tumor was made on the basis of the histological and immunohistochemical findings.

Tratamento cirúrgico de condroma extradural lombar em cão - relato de caso

Neoplasms originating in the spinal canal are uncommon in small animal veterinary clinic, but when present can cause significant neurological signs. Anatomically, these neoplasms can be classified as extradural, intradural-extramedullary and medullary. Extradural neoplasms are located outside the dura mater, but they can cause compression of the spinal cord. The chondromas are benign neoplasms characterized by the formation of cartilage and is rarely located in the spinal canal in both human and veterinary medicine. We describe a case of lumbar extradural chondroma in a dog that surgical decompression and removal of the mass allowed the resolution of clinical signs of paralysis with return of function of the hind limbs of the patient.
