Implantation of intrathecal infusion system for intractable pain therapy / 基础医学与临床

ABSTRACT

Objective To discuss the mechanism,procedures and effect of implantable intrathecal infusion system for intractable pain therapy. Methods Among the 4 patients with intractable pain,2 had cancer pain,2 had failed back syndrome.Before operation,Visual Analogy Scale(VAS) were 8～10.Three had bolus intrathecal injection screening trial,1 had bolus epidural injection screening trial.In the clinical trail,VAS all decreased to 75%～90%.(Results) They all had intrathecal infusion system implantation.After operation,Morphine was prescribed(intrathecally.) The dose was 1～(8 mg).They all had satisfied pain relief without serious drug adverse effects.Conclusion The effect of implantable intrathecal system for intractable pain was satisfied.The drug adverse effects were obviously alleviated.
