Abstract
Introduction
Bone cancer metastasis may produce severe and refractory pain. It is often difficult to manage with systemic analgesics. Chemical neurolysis may be an effective alternative in terminally ill patients.
Case report
The study included 40 patients randomly allocated into two groups: sub-Tenon’s blockade with Lidocaine plus Saline Solution (LS) or Lidocaine plus Clonidine (LC). IOP, OPA and OPP were measured before anesthesia, and 1, 5 and 10 minutes after the injection of anesthetic solution.
Discussion
This approach may be effective and safe as an analgesic option for refractory hip pain due to metastasis or pathologic fracture in terminally ill patients.

Resumo
Introdução
A metástase do câncer ósseo pode produzir dor intensa e refratária. Muitas vezes é difícil lidar com analgésicos sistêmicos. A neurólise química pode ser uma alternativa eficaz em pacientes terminais.
Relato de caso
Paciente terminal do sexo feminino com metástase de câncer gástrico no quadril com dor intensa. Bloqueios neurolíticos guiados por ultrassom do grupo de nervos pericapsulares e do nervo obturador foram realizados com fenol a 5%. Isso levou ao alívio satisfatório da dor por 10 dias, até o óbito do paciente.
Discussão
Esta abordagem pode ser eficaz e segura como opção analgésica para dor refratária no quadril devido a metástase ou fratura patológica em pacientes terminais.
