What precaution should be taken when using microfibrillar collagen as a hemostatic agent intrapoperatively?

Using microfibrillar collagen as a hemostatic agent intrapoperatively requires caution with respect to its interaction with an autologous blood salvage unit. When microfibrillar collagen is used, it can interfere with the blood salvage process. This is particularly significant because the collagen could be collected along with salvaged blood, potentially leading to complications such as embolization or clogging of the blood return system. Therefore, avoiding the use of microfibrillar collagen in conjunction with these units is a crucial precaution to maintain the safety and effectiveness of autologous blood transfusion practices during surgery.

In contrast, the other options present practices that do not align with the intended safety precautions for using microfibrillar collagen. Using it in conjunction with all blood products may not be advisable if specific interactions or patient conditions are present. Administering it before incision does not apply to its hemostatic purpose, as it is typically utilized during bleeding. Combining it with antibiotic powder is usually unnecessary and can complicate the clinical setting without evidence of beneficial outcomes.
