This study introduces a simple, disposable device for intraoperative reinfusion of shed blood. The method minimizes blood trauma, showing minimal hemolysis and platelet drop in canine experiments.

Area of Science:

Biomedical Engineering
Surgical Innovation
Transfusion Medicine

Background:

Intraoperative blood salvage is crucial for reducing allogeneic blood transfusions.
Existing methods can be complex or lead to significant blood cell damage.

Purpose of the Study:

To evaluate a novel disposable device for intraoperative reinfusion of autologous shed blood.
To assess the efficacy and safety of this device in minimizing blood trauma.

Main Methods:

A disposable polycarbonate container with an antifoam-coated filter was used.
Sodium citrate and shed blood were aspirated, followed by inverted reinfusion.
Canine models were used to test the device's performance.

Main Results:

Related Experiment Videos

The procedure demonstrated minimal hemolysis.
A minor decrease in platelet count was observed.
No mortality or morbidity was recorded in the experimental subjects.

Conclusions:

The disposable device offers a simple and effective method for intraoperative blood reinfusion.
This technique significantly reduces blood trauma compared to conventional methods.
The device presents advantages in terms of disposability and ease of use.
