Resumo

JUSTIFICATIVA E OBJETIVOS: A analgesia pós-operatória foi muito valorizada nos últimos anos. Os cateteres plexulares são boa opção para analgesia de qualidade com a mínima repercussão sistêmica. O presente estudo visou a avaliar a ocorrência de efeitos colaterais e complicações em analgesia pós-operatória com cateteres plexulares e identificar fatores de risco para colonização bacteriana nos cateteres. MÉTODO: Pacientes submetidos a operações ortopédicas entre março de 2005 e janeiro de 2007 receberam analgesia por cateteres de plexo. Foi avaliada a ocorrência de efeitos colaterais e de complicações com o uso da técnica. Em parte dos casos foi feita cultura da ponta do cateter. RESULTADOS: Foram estudados 433 pacientes. As incidências de retenção urinária e náuseas/vômitos foram de 1,3% e 16,6%, respectivamente. Houve colonização em 8,6% dos 280 cateteres examinados. Não houve infecções, lesões nervosas nem repercussões sistêmicas. CONCLUSÕES: O uso pré-operatório de antibióticos e o tipo de agulha utilizado foram fatores de risco para colonização dos cateteres.

Abstract

BACKGROUND AND OBJECTIVES: The importance of postoperative analgesia has increased over the years. Plexular catheters represent a good option for high quality analgesia with reduced systemic repercussions. The objective of the present study was to evaluate the incidence of side effects and complications in postoperative analgesia with plexular catheters and identify risk factors for bacterial colonization of the catheters.
METHODS: Patients undergoing orthopedic surgeries between March of 2005 and January of 2007 received analgesia via plexular catheters. The incidence of side effects and complications of this technique were evaluated. In some of the cases, the catheter tip was cultured.
RESULTS: Four hundred and thirty-three patients were evaluated. Urinary retention and nausea/vomiting had an incidence of 1.3 and 16.6%, respectively. Of 280 catheters examined, 8.6% were colonized. Infections, nerve lesions, or systemic repercussion were not observed.
CONCLUSIONS: The use of antibiotics preoperatively and the type of needle were the risk factors of infection identified.
