Central Line Medication Administration Guidelines

Preparation for Central Line Access

The American Society of Anesthesiologists recommends using aseptic techniques, including hand washing and wearing sterile gloves, when accessing a central venous catheter to minimize infection risk 1, 2, 3
Cleaning catheter access ports with an appropriate antiseptic, such as alcohol, before each access is recommended by the American Society of Anesthesiologists to reduce microbial contamination 1, 2
Capping central venous catheter stopcocks or access ports when not in use is advised to maintain sterility, as suggested by the American Society of Anesthesiologists 1, 2
The use of needleless catheter access ports can lower rates of microbial contamination of stopcock entry ports, according to the American Society of Anesthesiologists 2

The American Society of Anesthesiologists recommends wiping the port with an appropriate antiseptic, such as alcohol, and allowing it to dry completely before accessing the line 1, 2
Using a new sterile syringe and needle/needleless connector for each medication administration is advised by the American Cancer Society 4
Flushing the line with normal saline after medication administration is recommended by the American Heart Association to ensure complete drug delivery and prevent mixing of incompatible medications 5
For viscous drugs or rapid fluid boluses, using manual pressure or an infusion pump is suggested by the American Heart Association to ensure proper administration 5

The administration rate should be determined based on the specific medication being administered, the clinical situation, and the patient's clinical status and tolerance, as recommended by the American Heart Association 5
For emergency medications during resuscitation, rapid IV/IO bolus with flush is appropriate, according to the American Heart Association 5
For medications that may affect blood pressure or heart rate, slower administration with monitoring is recommended by the American Heart Association 5
For irritating medications, administration through a central line rather than peripheral access is preferred to minimize vein irritation, as suggested by the American Heart Association 5

For high-risk medications, the use of an infusion pump with appropriate safety limits is strongly recommended by the American College of Cardiology 6
Monitoring the patient for adverse reactions during medication administration, especially with high-alert medications, is advised by the American College of Cardiology 6
For parenteral nutrition or solutions with high osmolarity, central administration is preferred over peripheral to reduce the risk of thrombophlebitis, as recommended by the European Society for Clinical Nutrition and Metabolism 7, 8
The osmolarity rate correlates with phlebitis risk, so controlling the rate accordingly is suggested by the European Society for Clinical Nutrition and Metabolism 8

Implementing a bundle approach to reduce central line-associated bloodstream infections (CLABSI) is recommended by the American Cancer Society 4
Using alcohol caps for needleless connectors and chlorhexidine-impregnated dressings around catheter insertion sites can provide additional protection, as suggested by the American Cancer Society 4

Administering incompatible medications simultaneously or without proper line flushing should be avoided, as recommended by the American Heart Association 5
Incorrect interpretation of central venous pressure readings during fluid administration should be avoided, as advised by the American College of Cardiology 6
