04What happens in the body?
Using a port
The nurse cleans the skin, feels for the septum and inserts the needle. First the port is checked (blood returns, fluid runs freely). For long infusions the needle is secured with a dressing. At the end the port is flushed. An unused port is flushed from time to time; how often depends on the centre. Ask in advance about numbing cream if you wish.
