Summary

This study explores pre- and peroperative blood conservation techniques, including autotransfusion, normodilution, and pre-donation, to minimize biological changes during surgery. These methods offer viable alternatives to allogeneic transfusions.

Area of Science:

Surgical Techniques
Transfusion Medicine
Anesthesiology

Background:

Minimizing blood loss during surgery is crucial for patient outcomes.
Allogeneic blood transfusions carry inherent risks.
Exploring autologous blood conservation strategies is essential.

Purpose of the Study:

To review and detail methods for pre- and peroperative blood saving.
To assess the feasibility of these techniques without significant biological alteration.
To provide an overview of different blood replacement solutions.

Main Methods:

Peroperative autotransfusion: recovery, filtration, and reinfusion of intraoperative blood loss.
Peroperative normovolemic hemodilution: pre-operative blood withdrawal, volume replacement with expanders, and intraoperative reinfusion.

Main Results:

These techniques can be implemented without inducing significant changes in biological parameters.
Different replacement solutions are viable for volume management.
Each method offers a way to utilize autologous blood during surgical interventions.

Conclusions:

Pre- and peroperative blood saving strategies are effective in reducing reliance on allogeneic blood.
Autotransfusion, normodilution, and pre-donation are valuable techniques in surgical blood management.
These methods support patient safety by minimizing transfusion-related risks.
