Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Duration of surgery, length of hospital stay, preoperative laboratory, anesthesiological parameters, transfused volume of erythrocytes, subjective visualization of the operating area by the surgeon, subjective intraoperative blood loss by surgeon | — |
