BRAIN STEM DEATH Single largest source of transplantable organs. Physiological core of brain death. Diagnosis by clinical bedside means. No sophisticated investigations. 3 Steps – UK code. preconditions exclude reversible causes apnoea
PRECONDITIONS Deeply comatose. On a ventilator in ICU. Known cause of coma. All remedial measures taken.
WHEN ARE THE TESTS DONE? Preconditions and exclusion criteria satisfied. Failed attempts at reversal. At least 12 hours of vigorous management after admission.
WHAT ARE THE CONFIRMATORY TESTS? Absent brain stem reflexes. Apnoea test.
RETESTING Test twice with 6 hours gap. Ensure persistance of non-functioning brain stem. Time gap utilised for counselling. Cardiac death usually within 72 hours of brain stem death. After second apnoea test inform relatives about death and use of ventilator for organ perfusion only. Time of death is time of second apnoea test. Until family accepts reality of death do not approach for organ donation.
