1. Identify common symptoms experienced by patients with advanced illness. 2. Select or recommend medication options for specific palliative symptoms. 3. Discuss various pharmacologic interventions for common symptoms. 4. Define treatment measures in the last hours of life.
2 INTRODUCTION
2.8 million death/year in US, 1.4 million in hospice. It is important to address and manage each end-of-life symptom to improve the quality of life for the patient. An interdisciplinary team approach is beneficial throughout the care of the patient. This is evident when addressing more psychologically based symptoms, such as delirium.

Base the initial treatment on the severity of pain the patient reports. Mild – Non-opioid analgesic Moderate – Opioid Severe (Pain emergency)– Opioid Provide Rx. PRN analgesic medication “Take the medication if unexpected pain occurs.” “Call for an appointment to evaluate the pain problem.” Begin a bowel regimen.

25 DYSPNEA -OPIOIDS
Help relieve sensation of shortness of breath In the opioid naive patient, low doses of oral (2.5 – 5 mg) or parenteral morphine (1 – 2 mg), provide relief for most patients. More frequent dosing is more effective than higher doses if dyspnea not adequately treated. Generally requires lower doses than necessary for treatment of pain. “Start low, go slow.”
Johnson, et. al. Am J Hosp Palliat Care. 2016;33(2): 194-200. Rocker, et. al. Thorax 2009;64(10): 910-915. MECHANISM OF OPIOIDS FOR DYSPNEA
Uncertain. May diminish the chemoreceptor response to hypercapnia and hypoxia. May cause vasodilation, resulting in decreased dyspnea due to the resulting reduction in preload and pulmonary congestion. May result in a decrease in anxiety and the subjective sensation of dyspnea through a central effect. May treat underlying pain that is causing increased respiratory drive. No difference between morphine and other short- acting opioids.

Necessary at EOL. Lorazepam With Haloperidol vs Haloperidol Alone 90 randomized patients (mean age, 62 years; women, 42 [47%]), 58 (64%) received the study medication and 52 (90%) completed the trial. Lorazepam + haloperidol resulted in: reduction of Richmond Agitation-Sedation Scale (RASS) score at 8 hours (−4.1 points) vs. placebo + haloperidol (−2.3 points) (mean difference, −1.9 points [95%CI, −2.8 to −0.9]; P < .001). less median rescue neuroleptics (2.0mg) vs. placebo + haloperidol group (4.0mg) (median difference, −1.0mg [95%CI, −2.0 to 0]; P = .009) Perceived to be more comfortable blinded caregivers: (84% for the lorazepam + haloperidol group vs 37% for the placebo + haloperidol group; mean difference, 47%[95%CI, 14%to 73%], P = .007; nurses: 77% for the lorazepam + haloperidol group vs 30% for the placebo + haloperidol group; mean difference, 47%[95%CI, 17%to 71%], P = .005).
