Complications of intrathecal opioids and bupivacaine in the treatment of "refractory" cancer pain
Abstract
To test the concept that externalized tunneled intrathecal catheters lead to a high risk of complications, such as meningitis and epidural abscess, and therefore should not be used for durations of intrathecal pain treatment of > 1 week. Prospective, cohort, nonrandomized, consecutive, historical control trial. Tertiary care center, institutional practice, hospitalized and ambulatory care. Two hundred adults (107 women, 93 men) with refractory cancer pain treated for 1-575 (median, 33; total, 14,485) days; 79 patients were treated at home for 2-226 (median, 36; total, 4,711) days. All patients had died by the close of the study. Insertion of intrathecal tunneled nylon (Portex) catheters (223 in 200 patients) with Millipore filters. The catheter hubs were securely fixed to the skin with steel sutures. Standardized care after insertion: (a) daily phone contact with the patients, their families, or the nurses in charge; (b) weekly dressing change at the tunnel outlet by the nurses; (c) refilling of the infusion containers by the nurses; (d) exchange of the infusion systems when empty (within 1 month) and of the antibacterial filter once a month by specially instructed Pain Department nurses. All contact between the connections of ...Continue Reading

Cancer Incidence & Mortality
Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
