Cardiothoracic & vascular anesthesia
Effect of using smaller blood volume tubes and closed blood collection devices on total blood loss in patients undergoing major cardiac and vascular surgery
Authors' conclusion
Diagnostic laboratory tests are associated with significant patient blood loss, but are a modifiable risk factor. The use of small-volume tubes and closed blood collection devices decreases the volume of patient blood drawn for analysis and prevents blood waste.
Study context
- Population
- Consecutive adults (≥ 18 yr) undergoing major cardiac or vascular surgery
- Participants
- 400 adults
- Exposure
- Cardiac surgery vs Vascular surgery
- Outcome
- Daily phlebotomy volume (total blood loss due to phlebotomy)
- Follow-up
- During hospitalization
Methodological detailsconsecutive patients, estimation of blood saved with small-volume tubes and closed blood collection devices
- Consecutive patients
- Estimation of blood saved with small-volume tubes and closed blood collection devices
Main finding
As reported in the abstract
Mean total phlebotomy blood loss, standard-volume tubes, by hospital length of stay (LOS)
Observational data: associations, not effects.
Further findings
Mean phlebotomy blood loss by ICU stay
Blood loss reduction with closed blood collection device and small-volume tubes (serum, ethylenediaminetetraacetic acid (EDTA), sodium citrate coagulation (SCC), arterial blood gas (ABG))
- Reduction, ICU stay of 2 days
- 82.8 mL
- Reduction, ICU stay of ≥ 11 days
- up to 824.0 mL
- Estimated
