Intrathecal Catheter Insertion and Analgesia is a Safe and Effective Method of Pain Control in Patients with Advanced and Intractable Cancer Pain

Abstract

Introduction: Pain affects the quality of life in cancer patients. The World Health Organization established a simple three-step "ladder" approach in 1986, beginning with nonopioid drugs and progressing to stronger opioids as necessary. The implementation of this guideline enables analgesia to be achieved in 75% to 90% of patients. The remaining patients suffer from intractable pain requiring intrathecal analgesia. Advances in intrathecal analgesia and intrathecal drug delivery systems have allowed for a range of medications to be used in the control of pain in the remaining 20% of patients with intractable cancer pain. This technique allows for reduced medication doses that can decrease the side effects typically associated with oral or parenteral drug delivery. We aim to analyse the pain intensity before and after intrathecal analgesia and review the complications associated with the implantation and the care of the intrathecal device.
