Dose-response relationship between cell salvage volume, perioperative transfusion requirements, and postoperative clinical outcomes in cardiac surgery: A retrospective cohort study
Authors' conclusion
This first continuous dose-response analysis of CS volume in cardiac surgery found no association between CS volume and major complications at typical volumes.
Study context
- Population
- Adult cardiac surgery patients who received intraoperative cell salvage (CS), January 2023 to August 2025consecutive
- Participants
- 883 patients
- Exposure
- CS volume and perioperative transfusion and postoperative outcomes
- Outcome
- Perioperative transfusion requirements (with discriminative intraoperative thresholds) and postoperative clinical outcomes, by CS volume
Methodological detailsconsecutive patients, dose-response analysis
- Consecutive patients
- Dose-response analysis
Main finding
As reported in the abstract
Intraoperative coagulation product transfusion by CS volume · Intraoperative
- Median CS volume (L) [0.4-0.7]
- 0.5
- FFP, OR (p < 0.001)
- 6.18
- Platelets, OR (p < 0.001)
- 7.91
- Cryoprecipitate, OR (p < 0.001)
- 5.25
- Discriminative thresholds converged (L)
- 0.66-0.88
Observational data: associations, not effects.
Further findings
Postoperative transfusion
- Received blood products
- 64.9%
- Only cryoprecipitate associated with CS volume, OR (p = 0.006)
- 2.38
Drainage · Postoperative
- Increased drainage with CS volume, β mL (p = 0.023)
- 110
ICU stay
- Longer ICU stay with CS volume, β days (p = 0.010)
- 1.23
Safety
Major complications
- No associations with CS volume; rates favorable vs published benchmarks
