May support weighting anaesthetist estimates when objective measurement is unavailable; leaves open prospective validation before practice change.
Observational (n=100)
Are anaesthetists or surgeons more reliable at subjectively estimating operative blood loss compared to objective measurement?
Anaesthetists provide more reliable subjective estimates of operative blood loss than surgeons, suggesting joint estimation is preferable when objective measurement is impracticable.
A. E. Delilkan (1972) conducted an observational in Surgical cases requiring operative blood loss estimation (n=100). Subjective estimation of operative blood loss by anaesthetists vs. Subjective estimation of operative blood loss by surgeons was evaluated on Reliability of subjective estimates compared to colorimetric measurement. Subjective estimates of operative blood loss by anaesthetists were more reliable than those by surgeons when compared to objective colorimetric measurements.
