Phlebitis

Phlebitis

Infusion phlebitis originates from two main sources. One is mechanical the other is chemical. By far the most prevalent cause of infusion phlebitis is chemical in origin. Early recognition of phlebitis will help to maintain patient safety and comfort. Consideration of blood flow past the tip of the catheter must be viewed in association with the chemical composition of the drug to be infused. A pH between 5 and 9 is considered appropriate for safe peripheral administration. However, Stranz and Kastango (2002) describe how a phlebitic episode depends upon the type of tissue that the drug is coming into contact with. They further describe “In vitro experiments have demonstrated that solution pH values of 2.3 and 11 kill venous endothelium cells on contact.”
