Critical care specialists, the missing link in organ procurement for transplantation

Table 1 Modified Maastricht classification of donation after cardiac death and the locations where it is mainly practiced[19]

Category	Description	Type of DCD	Locations practiced
I	Dead on arrival	Uncontrolled	ED in a transplant center
II	Unsuccessful resuscitation	Uncontrolled	ED in a transplant center
III	Anticipated cardiac arrest	Controlled	ICU and ED
IV	Cardiac arrest in a brain-dead donor	Controlled	ICU and ED
V	Unexpected arrest in ICU patient	Uncontrolled	ED in a transplant center

Despite the differences of Maastricht I, II and V from III and IV types, post transplantation clinical outcomes are similar to brain death derived organs[18]. DCD: Donation after cardiac death; ICU: Intensive care unit; ED: Emergency department.
