Final inline filtration for intravenous infusions: a prospective hospital study

Area of Science:

• Medical Science
• Biomedical Engineering

Background:

• Phlebitis is a frequent complication of intravenous therapy, impacting over 50% of infusions.
• Particulate matter in intravenous fluids is a suspected cause of phlebitis.

Purpose of the Study:

• To evaluate the efficacy of a 0.2-micron inline filter in reducing phlebitis during intravenous therapy.
• To assess the impact of inline filtration on the duration and complication-free survival of intravenous infusions.

Main Methods:

• A randomized controlled trial comparing a 0.2-micron inline filter with a dummy device for intravenous infusions longer than 48 hours.
• Infusions were randomized, and outcomes were monitored to determine phlebitis incidence and infusion survival rates.

Main Results:

• Inline filtration significantly prolonged phlebitis-free survival of infusions (P < 0.01).
• Infusions utilizing the filter demonstrated a higher survival rate until no longer required compared to the dummy group (63 vs. 38).
• The benefits of inline filtration were most pronounced in infusions where antibiotics were administered (P < 0.01).

Conclusions:

• Inline filtration effectively delays the onset of phlebitis, increasing the number of infusions that survive until completion.
• While not strong enough for a universal hospital policy, inline filters are indicated for patients requiring intravenous antibiotics.
