Clinical Trial Summary

There is widespread acceptance that air in intravenous (IV) fluid tubing (lines) can pose a significant risk to patients.1 A rigorous literature search regarding sources of this air identified only anecdotal and non-clinical work regarding the presence and sources of air in IV tubing. Most published case studies have focused on air entrainment from accidental or inadvertent sources - empty IV fluid bags, incomplete priming of the tubing prior to infusion, and air-detection device failures, as examples.

The sources (and volume) of air inside IV tubing during common surgical procedures or interventions have yet to be studied prospectively. Understanding the frequency and magnitude of the presence of unintended air in IV tubing is the first step in devising potential avoidance strategies for eliminating unintended air in IV tubing. This study was designed to identify both the sources and magnitude of air that occurs in IV tubing during routine surgical procedures.

Description:

Methods:

An observational prospective trial was conducted in operating room settings across multiple study sites. 120 surgical patients undergoing a variety of interventional and surgical procedures were selected, representing multiple patient populations, case types and anesthesia setups. The ClearLine IV, a device that detects and removes air from IV tubing, was inserted into the IV circuit. Clinicians followed standard protocols. Blood warmers were used at the practitioner's discretion. IV fluid was administered at a constant flow rate or through a bolus given over 30-60 seconds per standard of care. The volume and duration of fluid administration was recorded, along with the frequency, duration and amount of air captured by ClearLine IV.
