Double and Triple Lumen Catheters, Administration of Drugs, and Sterilisation of Longlines/CVL using antibiotics
Charge Nurse - Newborn
Double and Triple Lumen Catheter, CVL/UVC
- Should be used in all large
babies sick enough to require central access (exception – infants
- For smaller infants, individual clinical
assessment is required. Reserve for those thought to require multiple
- Each lumen remains separate when
enclosed together within the outer catheter i.e. the different
medications do NOT mix.
- The flow past the tip of the catheter is
so great that incompatibility does not occur.
- When one or more lumen is luered each
lumen will need to be flushed every 72 hours by using the
Recommended Best Practice as for single lumen central venous catheter.
- The luered lumens need flushing with 1ml
heparinised saline – 10 units/ml.
Administration of Drugs via a Double Lumen luered catheter
Lumen are labelled 1 and 2.
Antibiotics are administered over the 24
hour period via 1 lumen then the other lumen is used for the next 24 hrs.
- Even date give by No 2 lumen
- Odd date give by No 1 lumen
Preparation, administration, flushing of
line is the same as for administration of drugs via a luered central
Double lumen catheter have a primary and
secondary lumen. Each has a different
Sterilisation of Long line/Central Venous Catheter using antibioticsWhen there is suspected
line sepsis, medical staff may order antibiotics to be given through the
line. Although there is conflicting information in the literature, there
has been research which indicates high success in treating line sepsis
Vancomycin is often used for this purpose.
Points to remember:
- Fluid administration through the CVL/LL
will be ceased on medical order.
- A pall filter with luer on the end is
primed with heparinised saline 10 units per ml and attached to the long
line/central venous catheter.
- No dextrose solution is administered
through the catheter.
- The antibiotic should be diluted with
saline not dextrose. In the case of Vancomycin this will be quite a
large volume. The strength of saline to be used should be specified by
the doctor/NS-ANP and the added sodium calculated into the baby’s total
- It may be preferable to leave the
Vancomycin in the catheter and not flush to end the procedure. Because
the dead space in a Davol catheter is small, the baby will receive
sufficient antibiotic and flushing at the commencement of the next
dose will not cause a bolus of the drug.
- If flushing is required to end the
procedure, normal saline should be used before heparinised saline
Heparin is incompatible with Vancomycin.
