At present, many patients heavily dependent on medical care live at home. Therefore, the need for pain control at home is increasing. Within the limits of home care, the method used to control pain control is very important. Here we report 2 cases who need more than 1,000 mg of morphine (converted into oral administration). And we introduce our method for pain control at home. Our method is as follows: 1. Before the patient is discharged from the hospital, we go to the hospital and confirm the patient's condition and pain. 2. If necessary, before the patient is discharged from the hospital, we request to change instruments for home care. 3. We select the best way (instruments, circuits, administration) in consideration of the patients' or their families ADL. 4. When we change a route from oral administration to injection, we let the patient enter the hospital temporarily to adjust the quantity of morphine.
