- Primary Outcome Measures
Name Time Method Intraoperative Blood loss: After the operation, the weighing of the required wipes, the measurement of the rinsing liquid and the liquid in the surgical aspirator aswell as the filling of the corresponding attached protocol are carried out by the surgeon and the assistant nurse. Thus, the intraoperative blood loss can be determined as the main target and statistically checked whether there is a significant difference between the two groups.<br>
- Secondary Outcome Measures
Name Time Method 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
