Impact of Blood Sampling Methods on Blood Loss and Transfusion After Pediatric Cardiac Surgery: An Observational Study
Authors' conclusion
The closed-loop sampling method can be efficient in decreasing blood loss during postoperative PICU follow-up for pediatric patients after cardiac surgeries. However, its application did not reduce the frequency or the volume of blood transfusion in these patients.
Study context
- Population
- Children <4 years admitted to the pediatric intensive care unit (PICU) after cardiac surgery, single tertiary center
- Participants
- 100 vs 43
- Exposure
- Closed-loop vs nonconservative blood sampling
- Conservativen = 100
- Nonconservativen = 43reference
- Outcome
- Volume of blood loss during PICU follow-up

Main finding
As reported in the abstract
Blood loss during follow-up
P = 0.012
Observational data: associations, not effects.
Secondary outcomes
Blood transfusion volume (first 24 h, first 48 h, after 48 h)
- No significant differences between groups (p = 0.061, 0.536, 0.442, respectively)
Blood transfusion frequency (first 24 h, first 48 h, after 48 h)
- Comparable between groups (p = 0.277, 0.639, 0.075, respectively)
Duration of mechanical ventilation, intensive care unit (ICU) LOS, hospital LOS, mortality
- No significant differences between groups
