Surgeons visually estimate blood loss (EBL) inaccurately, underestimating actual amounts. Calculated blood loss (CBL) offers a more precise measurement, especially in complex plastic surgery procedures.
Area of Science:
- Plastic Surgery
- Surgical Outcomes
- Patient Safety
Background:
- Estimated blood loss (EBL) is subjective and often inaccurate.
- Calculated blood loss (CBL) provides a more objective and accurate measure of blood volume lost.
- Accurate blood loss assessment is crucial for guiding patient care and management.
Purpose of the Study:
- To compare Estimated Blood Loss (EBL) with Calculated Blood Loss (CBL) in plastic surgery.
- To identify discrepancies between visual estimation and objective measurement of blood loss.
- To evaluate the reliability of CBL as an alternative to EBL.
Main Methods:
- Retrospective analysis of 35 plastic surgery patients.
- Procedures included DIEP flaps, oncoplastic surgery, breast reductions, and mastectomies.
- Comparison of EBL and CBL data from multiple surgeons.
Main Results:
- Surgeons significantly underestimated blood loss (median EBL 250 cc vs. CBL 388 cc).
- A senior surgeon showed less underestimation compared to a junior surgeon.
- Complex procedures like DIEP flaps and breast surgeries had higher CBL and greater EBL-CBL discrepancies.
Conclusions:
- Surgeons tend to underestimate blood loss, with variations based on experience and procedure complexity.
- Calculated blood loss (CBL) is a more reliable measure than EBL.
- CBL should be considered a valuable alternative for accurate blood loss assessment in plastic surgery.
