Resumo

JUSTIFICATIVA E OBJETIVOS: O surgimento de casos de paraplegia seguindo a inserção de cateter peridural em pacientes anestesiados levou a questionamento por parte de alguns autores, mesmo que não se confirme que a lesão tenha ocorrido porque o paciente estava anestesiado. Por esse motivo, idealizamos este estudo, que teve como objetivo avaliar a freqüência de complicações neurológicas e de surgimento de seqüelas após anestesia peridural torácica realizada com os pacientes sob anestesia geral. MÉTODO: Participaram do estudo pacientes submetidos à intervenção cirúrgica torácica no período de 16/02/2004 a 30/05/2006. Após monitoração dos sinais vitais e realização da anestesia geral, os pacientes foram colocados em decúbito lateral e realizada anestesia peridural torácica simples ou contínua. Numa ficha especial foram registradas as intercorrências, complicações e dificuldades na realização da técnica. No pós-operatório os pacientes foram acompanhados em busca de sinais e sintomas de disfunção neurológica. RESULTADOS: Foram avaliados 113 pacientes e em 108 foi inserido cateter peridural torácico. Em 45 pacientes a punção foi considerada traumática, ou seja, sangramento no local da punção e punções múltiplas. Em dois pacientes houve perfuração acidental de dura-máter. No pós-operatório imediato um paciente relatou sensação de formigamento em membros inferiores, outro paciente apresentou dormência em membro superior, desaparecendo com a retirada e tração do cateter. A punção foi única nos dois casos. Nenhum outro paciente apresentou sinais ou sintomas de alterações neurológicas. CONCLUSÕES: Nos casos estudados não houve complicação neurológica. Quando executado com bom senso e cuidados específicos o bloqueio peridural torácico pode ser realizado com segurança no paciente anestesiado.

Abstract

BACKGROUND AND OBJECTIVES: The development of paraplegia following the insertion of epidural catheter in anesthetized patients raised questions by some authors about the procedure, even without the confirmation that the lesion occurred because the patient was anesthetized. For this reason, we designed this study, with the objective to evaluate the frequency of neurological complications and development of sequelae after thoracic epidural block in patients under general anesthesia. METHODS: Patients undergoing thoracic surgeries from 02/16/2004 to 05/30/2006 participated in the study. After monitoring vital signs and the installation of general anesthesia, patients were placed in lateral decubitus for simple or continuous thoracic epidural block. Intercurrences, complications, and technical difficulties were recorded on a special form. Patients were followed postoperatively to detect the development of any signs and symptoms of neurological dysfunction. RESULTS: One hundred and thirteen patients were evaluated and the thoracic epidural catheter was placed in 108 patients. The puncture was considered traumatic, i.e., bleeding at the puncture site and multiple punctures, in 45 patients. Accidental perforation of the dura-mater occurred in two patients. In the immediate postoperative period, a patient complained of tingling in the lower limbs, another patient developed numbness in an upper limb, which resolved after the catheter was removed. Both patients had a single puncture. The other patients did not develop any signs or symptoms of neurologic changes. CONCLUSIONS: The cases studied here did not develop any neurologic complications. When performed judiciously and with specific care, thoracic epidural block can be safely done in the anesthetized patient.
