E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
It is therefore the aim of the proposal presented to describe an additional approach, in which perioperative, surgical blood loss iron losses are replaced immediately following the surgical procedure in patients that did not receive iron preoperatively due to normal or minor reduction in hemoglobin concentrations (red cell mass). This replacement may take place in either the postoperative anesthesia care unit or in the ICU, Although preoperative treatment of iron deficiency anemia is widely considered the most important domain of perioperative iron therapy, the additional post-operative replacement is as useful as preoperative preparation and seems to be more convenient to implement. |
Ziel des vorliegenden Vorschlags ist es daher, einen zusätzlichen Ansatz zu beschreiben, bei dem perioperative, chirurgische Blutverluste durch Eisenverluste unmittelbar nach dem chirurgischen Eingriff bei Patienten ersetzt werden, die aufgrund einer normalen oder geringen Reduzierung der Hämoglobinkonzentration (Erythrozytenmasse) kein Eisen präoperativ erhalten haben. Dieser Ersatz kann entweder auf der postoperativen Anästhesie-Station oder auf der Intensivstation erfolgen. Obwohl die präoperative Behandlung der Eisenmangelanämie weithin als wichtigster Bereich der perioperativen Eisentherapie gilt, ist der zusätzliche postoperative Ersatz genauso nützlich wie die präoperative Vorbereitung. |
