A lesson in futility

Coded the baby for 2 hours this morning, No heart rate, epi epi epi epi, chest compressions, chest compressions, chest compressions. Intubated the baby and hired human mechanical ventilators. Started on digoxin, broadened antibiotics. Heart rate 80, heart rate 55, heart rate 0, heart rate 75. Walked away and the baby arrested again, did it all again. Pupils dilated, extremities ice cold. Barely any O2 is seeing the brain. Felt like everyone was looking at me like  'let him go doc'. I guarantee that as soon as I leave, they will let him die. But what can I do?
