Abstract
A method of significantly enhancing the period of time that an implanted intraperitoneal catheter used for the delivery of therapeutic medication will operate without encountering significant blockage by fibrotic tissue is disclosed. By monitoring and maintaining certain physical parameters in patients having an implantable catheter below desirable levels for the parameters, catheter survival in the patients is maximized. The four parameters used are blood triglyceride level, blood cholesterol level, the level of insulin dosage per day, and mean blood glucose (MBG) level, with the first two being the more accurate parameters.
