Treatment: Antibiotic Delivery System

This system enables the easy and regular delivery of intravenous antibiotics and is particularly useful for children with cystic fibrosis. Under general anaesthesia, the internal part of the system is placed on the chest wall just under the skin so that it does not interfere with the child’s normal activities. A catheter carries the injected antibiotics from the injection site to a vein in the chest just above the heart. The external part of the system is removable.

The injection procedure

The external part of the injection system is positioned over the internal part so that the sterile needle pierces the injection site. Antibiotics are injected into the delivery tube and pass through the catheter into the circulation. Local anaesthetic cream is often used to numb the skin beforehand.
