Cardiothoracic & vascular anesthesia
Single-Center Experience with Sonic Estimation of Elasticity via Resonance (SEER)-Guided Hemostasis in Adult Cardiac Surgical Patients
Authors' conclusion
In the majority of cases, providers made transfusion decisions that were concordant with predefined SEER cutoffs. Patients with transfusion decisions that were concordant with SEER cutoffs appeared to have less postoperative bleeding.
Study context
- Population
- Adults undergoing cardiac surgery with cardiopulmonary bypass (CPB) over a 1-year period, single academic medical center
- Participants
- 448 adults
- Exposure
- Concordant vs Not concordant
- Concordantn = 260
- Outcome
- Transfusion decision concordance with predefined SEER cutoffs for relevant blood products

Observational data: associations, not effects.
Secondary outcomes
24-hour chest drain output
P < 0.05
RBC transfusion in the first 24 hours after surgery
P < 0.05
Reoperation for bleeding
P < 0.05
PCS and FCS values vs bleeding
- Lower PCS and FCS values associated with more intraoperative blood loss and higher 24-hour chest drain output
