Intravenous placement device and infusion thrombophlebitis

Area of Science:

• Medical devices
• Patient safety
• Infection control

Background:

• Thrombophlebitis is a common complication of intravenous therapy.
• The choice of intravenous access device and duration of infusion are potential risk factors.

Purpose of the Study:

• To evaluate the incidence of thrombophlebitis associated with different intravenous cannulas.
• To determine the relationship between infusion duration and thrombophlebitis.

Main Methods:

• Prospective study comparing thrombophlebitis rates.
• Utilized short teflon cannula, stainless steel needle, scalp vein needle, and long teflon cannula.
• Monitored patients over 24-hour infusion periods.

Main Results:

• Overall thrombophlebitis incidence was 18.3%, all mild grade.
• Short teflon cannulas showed a higher incidence (24%) compared to other devices.
• Thrombophlebitis incidence increased significantly with infusion duration, from negligible at 8 hours to 63.7% at 24 hours.

Conclusions:

• Short teflon cannulas may be associated with a higher risk of mild thrombophlebitis.
• Infusion duration is a critical factor in the development of thrombophlebitis.
• Further research into optimal cannula selection and infusion protocols is warranted.
