  • Notas adicionales en la data
    Medtronic Inc. recently conducted a survey of the occurrence of chronic inflammation or granuloma in the distal portion of intrathecal catheters used in implantable infusion pumps (IsoMed, SynchroMed II and SynchroMed EL), particularly in cases of use of these same pumps in opioid infusion therapies, baclofen, drug-drug compounds and other pharmacological preparations. The exact cause of inflammatory mass formation is still unknown, but the higher rate of occurrence of this problem is associated with the use of opioids, particularly when using high doses, or high concentration doses, of morphine sulfate and / or other opioids. In December 2007, the company estimated the incidence rate of inflammatory mass (from reported cases) in patients implanted and submitted to infusion of drugs for pain treatment by 0.49%, higher than the incidence rate of 0, 1% reported in 2001. Medtronic Inc.'s expectation is that the rate of reported occurrences of this problem will increase as cases of this type have occurred between 6 months and> 10 years after implantation of the infusion device in patients. The symptoms reported in patients are as follows: decreased therapeutic response / inadequate attenuation of pain, pain, neurological dysfunction, paralysis / paraplegia, muscle weakness / weakness, numbness, incontinence, motor difficulties, urinary retention, tingling sensation, and headache . The risk of this problem occurring seems to be cumulative over time and increases as higher concentrations of opioids are used in the treatment.
  • Causa
    Possibility of inflammatory mass formation at the tip of the intrathecal catheter used in isomed and synchromed ii implantable infusion pumps.
  • Acción
    The company that manufactures the product (Medtronic Inc. - USA) recommends that intrathecal opioids be administered in a way to provide an adequate analgesic action using the lowest doses possible. Physicians who accompany patients implanted with these infusion pumps should implant a routine of monitoring specific to the needs of each patient, aiming to identify the formation of inflammatory mass from clinical signs and symptoms presented. Special attention should be given to patients whose implant is used for infusion of drug-compound drugs, or preparations that include baclofen and opioids. The company currently in possession of the product registration in Brazil (DABASONS LTDA) informed the Anvisa's Technovigilance Unit that it has already initiated contact with its clients involved in this action, through letters of communication. According to the company, 484 units of these devices were marketed in Brazil to date, and there are also 28 non-marketed units retained in stock. The company said it had not marketed the Synchromed EL (also at risk) implantable infusion pump in Brazil. Anvisa's Technovigilance unit is following up on this case.
