Non-heart-beating donation

Non-heart-beating donation (pronunciation: non-hart-beeting doh-nay-shun) is a term used in the field of medicine and organ transplantation to refer to the procurement of organs from donors who are not brain-dead but whose hearts have stopped beating, also known as cardiac death.

Etymology

The term "non-heart-beating donation" is derived from the English words "non", meaning not, "heart", referring to the organ that pumps blood through the body, "beating", a term used to describe the rhythmic contraction and expansion of the heart, and "donation", which refers to the act of giving.

Definition

Non-heart-beating donation, also known as donation after cardiac death (DCD), involves the retrieval of organs after the donor's heart has ceased to beat. This is in contrast to donation after brain death (DBD), where the donor's heart is still beating at the time of organ retrieval.

Procedure

The procedure for non-heart-beating donation typically involves the following steps:

1. The potential donor's heart stops beating.
2. A period of 2-5 minutes is observed to ensure that the heart does not restart on its own.
3. The death of the donor is declared.
4. The organs are quickly retrieved to minimize the time they are without blood flow.
