NCT ID: NCT05820828 Completed - Clinical trials for Extracorporeal Circulation; Complications

Comparing Air Embolic Load in Two Venous Cannulation Methods, 40 Patients Undergoing Elective Valve Surgery.

Start date: April 21, 2023
Phase: N/A
Study type: Interventional

The goal of this single center prospective controlled observational and interventional trial is to investigate and compare origin of air emboli when different venous cannulation methods is used in patients undergoing cardiac surgery with extracorporeal circulation. 40 consecutive elective patients will be included in two groups, depending on the procedure requiring bicaval or cavoatrial cannulation. After assorted into respective group, patients will be block randomized (five groups consisting of eight patients each) to either intervention group (low venous reservoir volume, 200-300 mL) or control group (venous reservoir volume > 300 mL). Primary endpoint is to investigate if the amount of air emboli passing through the oxygenator to the arterial line differs between bicaval and cavoatrial venous cannulation during extracorporeal circulation. Secondary endpoints are the relative difference in amount air emboli between the groups, if there is any correlation between the amount of air in venous line and the amount of air passing through the oxygenator to the arterial line during extracorporeal circulation, and if difference is seen on the amount of air passing through the oxygenator depending on the level of volume in the venous reservoir.

Factors Increasing Air Burden in Intravenous Tubing

Start date: August 16, 2016
Phase: N/A
Study type: Interventional

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.
