Palliative care The principles of palliative care as outlined by the World Health Organization (WHO) are: 1) Preserve life and recognize near death as a normal process; 2) Do not hasten or delay death; 3) Reduce pain and other distressing symptoms; 4) Provide physical, psychological, social and spiritual (i.e., physical, mental, social and spiritual) support to patients until they die; 5) Provide family members with grief comfort and other assistance during the patient’s serious illness and death. The doctor is the core of the team, communicating with the patient and family to understand the patient’s wishes, discussing treatment options, the advantages and disadvantages of various rescue and treatment measures, and signing relevant medical documents and issuing medical orders for palliative care, including giving the patient medication to relieve the patient’s physical symptoms, such as diuretics to reduce the patient’s Pulmonary edema, lower extremity edema, giving oxygen, using drugs to reduce respiratory secretions to improve the patient’s dyspnea, using morphine to relieve pain, etc. 2. Nurse: is the actual operator who performs the above treatments for the patient according to the doctor’s orders. The nurse is the bridge between the patient and the doctor, spending more time with the patient, understanding the patient’s physical condition and psychological needs, assisting the doctor to provide better services for the patient, and also providing more psychological support for the patient and family. 3.Nursing staff: personal cleaning and nursing work for patients, including cleaning patients’ excrement, keeping the bed dry and clean, etc., to make the patient’s body as neat and comfortable as possible. 4.Psychiatrist or psychotherapist: Provide psychological support and treatment for patients and families to help them face the great psychological pressure they face when facing incurable diseases and terminal states. For families with religious beliefs, religious services and psychological comfort can be provided by the clergy. 5.Social workers: Liaise with patients to arrange other medical-related services, such as contacting insurance companies to verify medical insurance and costs, and making appropriate arrangements for patients who need home visitation services and hospice care, etc. 6. Community volunteers: accompany patients, especially when their family members cannot come at all times, to chat, read newspapers, watch TV and movies together to reduce patients’ loneliness and give them psychological comfort. It is important to note that palliative care is not euthanasia and does not actively provide drugs to speed up the patient’s death; nor is it passive waiting for death, but rather actively provides symptom relief and psychological care to optimize the patient’s death process with palliative support therapy. Patients who receive palliative care services enjoy dignity and privacy, have control over what happens; recognize that death is a reality and an inevitability, just like birth, growth, maturity and old age; are able to use a “living will” to ensure that their wishes are respected; have the right to choose the place of death (including at home); and have access to care anywhere, not just in a hospital. The right to receive care anywhere, not just in the hospital; the right to receive the information they need, as well as spiritual and emotional support; the right to adequate pain relief and to be as comfortable as possible; the right to have time to say goodbye, to decide who will be there to visit, and to decide how the rest of the time will be arranged and with whom they will share their final moments; and the right to leave in time for an eternal goodbye, without meaningfully delaying life. ”The ultimate goal of palliative care is to allow the dying to experience the most benign and optimal death possible, so that they can die in the last days of their lives in as much comfort, dignity, preparation and peace as possible.
