A 62-year-old man with end-stage head and neck cancer is being managed in a palliative care unit. He has a massive fungating neck mass and has recently developed intractable, agonizing pain and secondary agitated delirium. Over the past 48 hours, his symptoms have remained unbearable despite aggressive escalation of intravenous opioid infusions, ketamine, and scheduled haloperidol. The interdisciplinary team, in consensus with the primary palliative care physician, determines that all symptom-directed therapies have been exhausted. The patient's wife, who is his designated healthcare proxy, is severely distressed and states, 'He previously told me he just wants to sleep if the pain gets this bad. Please, just put him to sleep so he doesn't suffer anymore.' The physician decides to proceed with palliative sedation.
Arrange the following steps for initiating and managing palliative sedation in the correct sequential order.
- 1Document the refractory nature of the symptoms and confirm the exhaustion of all standard targeted therapies.
- 2Obtain and document specific informed consent from the surrogate for proportional sedation to unconsciousness.
- 3Discontinue routine cardiopulmonary monitoring and non-comfort-oriented interventions.
- 4Administer an induction bolus of a sedative agent (e.g., midazolam) followed by a continuous intravenous infusion.
- 5Titrate the sedative infusion based strictly on standardized observational scales of comfort and awareness.
