Drug pumps: Applications

21 October 2017

Drug pumps in pain management (pain medication pumps) ensure a uniform drug delivery into the blood and the cerebrospinal fluid. Also can output directly into the tissue, such a pump analgesics, for example for local anesthesia (local anesthesia). In pain, a drug pump particular helps people with very great pain, such as after surgery or certain cancers.

In particularly severe discomfort the classic pain treatment with tablets is often not enough to relieve the pain sufficiently. Continuous administration of analgesics on the vein (IV) may be advantageous here. If the patient can adapt to its requirements, the drug delivery within limits itself, it is also called a patient-controlled pain therapy (PCA).

Drug pumps in pain management function according to the so-called Basal-bolus approach: Depending on the individual constitution, time of day and the activity of the patient, the doctor that the drug pump continuously and slowly releases (basic concept) lays for 24 hours a certain amount of painkillers found. In particular pain points of the patient independently an additional predetermined amount of medication (bolus) can retrieve. In order to avoid overdosing, the number of possible bolus doses is limited within 24 hours electronically. With the medication pump, the patient can move freely, adjust the pain medication dose as needed individually and thereby gain greater independence and a better quality of life.

Drug pumps are also used in diabetes mellitus ("diabetes") for use. Diabetes mellitus is a chronic disease: Under certain circumstances - for example, when a so-called Type I diabetes is present - are diabetic life dependent insulin to the administration of the hormone. Often it is sufficient if the sick administered as required, for example, before eating, insulin. In some forms of the disease, it is desirable to have a uniform delivery of insulin to ensure. Here, an insulin pump that continuously releases a predetermined amount of the active ingredient throughout the day helps. The drug pumps are equipped so that they also individual needs of patients consider: Does the carrier during the day more insulin, he can own a predetermined amount of the hormone administered (bolus).

Drug pumps have an important role in tumor therapy. They allow stakeholders a local flexibility. Anticancer drugs often are only effective when administered directly into the bloodstream (infusion). Often takes the infusion a few minutes to a few hours. Sometimes, however, is also a continuous infusion needed over 24 hours. A portable medication pump allows the person concerned to move freely.
