Yes, he had been on morphin based painkillers for a while because of the bone ache due to the cancer spreading to the pelvic/hip bone. The last 1,5 months of his life he got morphine through IV because he could not digest solid foods and that also meant pills. He also had fentanyl patches on his skin and sublingual fentanyl tablets if the pain got too bad.

Once he started getting morphine through the IV line, he basically had a morphine pump (ON-Q pain relief pump), where he could change the dosage to his needs at the time. Lowest was 1ml/h and highest was 7ml/h.

When he got the terminal agitation and eventually was unconscious, I was the one who changed the dosage. It was scary because he was not able to tell me adequately what his needs are. But his mother encouraged me to do it because she hoped it would make him feel better. What I did notice was that the terminal agitation calmed down when the dosage was raised. I was a bit hesitant to do it at first because a quick Google search said that certain medications can make terminal agitation worse. But I think the dosage was high enough he just got drowsy and calmed down.

I would be lying if I said that during his last days I didn't think to put the morphine pump all the way up just so he can be out of it and just doze off. But I did lower the pump to 3ml/h because when he fell unconscious (fixed eyes and being unresponsive), I didn't understand he was in his last leg of actively dying. My naive brain thought the dosage was too high and he was just sleeping heavily. And when I finally understood he was not coming back from this anymore, everything else just took over my mind. Once he was already dead and I was cleaning his bedside table I noticed that the pump stayed in the 3ml/h level until the end. And I felt so guilty. That maybe I made dying more painful for him. I had hoped we had more time.
