11.1 Pain Management, Palliative Care, and End-of-Life Nursing
Key Takeaways
- Pain is whatever the patient says it is, existing whenever they say it does; self-report is the gold standard, and behavioural tools are used only when self-report is impossible.
- Around-the-clock dosing controls persistent pain better than as-needed dosing, and breakthrough doses are given in addition to, not instead of, the regular schedule.
- Opioid-induced constipation is universal and does not resolve with tolerance, so a stimulant laxative is prescribed prophylactically at the same time as the opioid.
- Sedation precedes clinically significant respiratory depression, so a rising sedation score is the earliest warning sign and matters more than the respiratory rate alone.
- Physical dependence and tolerance are expected physiological responses to opioids and are not addiction; withholding adequate analgesia for fear of addiction in a patient with severe pain is a recognised failure of care.
11.1 Pain Management, Palliative Care, and End-of-Life Nursing
Pain questions are usually ethics questions in clinical clothing. The examiner wants to see whether you accept the patient's report, whether you act on it, and whether you can do so safely.
Assessing Pain
Self-report is the gold standard. McCaffery's definition — pain is whatever the experiencing person says it is, existing whenever they say it does — is the operating rule. A patient who is laughing, sleeping, or chatting may still be in severe pain; behaviour is a poor proxy, because people adapt, distract, and mask.
Use a structured framework such as PQRST or OPQRSTUV: Provocation and palliation, Quality, Region and radiation, Severity, Timing, plus Understanding and Values. Reassess after every intervention at an interval matched to the route — roughly 15 to 30 minutes after intravenous, 30 to 60 minutes after oral.
Tool selection by patient:
| Patient | Tool |
|---|---|
| Adult, able to self-report | Numeric rating scale 0–10; visual analogue scale |
| Child 3 years and older | Wong-Baker FACES |
| Infant / preverbal child | FLACC (Face, Legs, Activity, Cry, Consolability) |
| Neonate | NIPS or PIPP |
| Non-verbal adult with advanced dementia | PAINAD |
| Intubated or sedated critical care patient | Critical-Care Pain Observation Tool (CPOT) |
For a patient who cannot self-report, combine an observational tool with knowledge of pathology (assume that a condition known to be painful is painful), with proxy report from family, and with an analgesic trial — if the behaviour improves after analgesia, pain was the cause.
The WHO Analgesic Ladder and Adjuvants
| Step | Pain severity | Agents |
|---|---|---|
| 1 | Mild | Non-opioid: paracetamol, NSAID ± adjuvant |
| 2 | Moderate | Weak opioid: codeine, tramadol ± non-opioid ± adjuvant |
| 3 | Severe | Strong opioid: morphine, oxycodone, hydromorphone, fentanyl ± non-opioid ± adjuvant |
Three principles carry most of the exam weight. By the clock: persistent pain is treated with scheduled around-the-clock dosing, with breakthrough doses in addition to, never instead of, the regular schedule. By mouth: use the oral route wherever it works. By the ladder: escalate to match the pain rather than working up from the bottom in a patient already in severe pain.
Adjuvants treat pain that opioids treat poorly. Neuropathic pain — burning, shooting, electric-shock quality, with allodynia — responds to gabapentin, pregabalin, amitriptyline, or duloxetine, not to escalating opioids. Bone pain responds to NSAIDs and bisphosphonates; malignant nerve compression and raised intracranial pressure to corticosteroids; muscle spasm to antispasmodics.
Opioid safety
- Constipation is universal and, unlike sedation and nausea, no tolerance develops. Prescribe a stimulant laxative prophylactically at the same time as the opioid; bulk-forming agents are ineffective and risk obstruction.
- Sedation precedes respiratory depression. Monitor a sedation score alongside the respiratory rate; a patient becoming progressively harder to rouse is the early warning, and waiting for a respiratory rate under 8 is waiting too long.
- Naloxone reverses opioid toxicity but has a shorter half-life than most opioids, so the patient must be observed for re-sedation and may need repeated doses or an infusion. In a patient with chronic opioid exposure, titrate carefully to restore respiration without precipitating acute withdrawal and a pain crisis.
- Meperidine (pethidine) should be avoided for repeated dosing because its metabolite normeperidine accumulates and causes seizures; it is contraindicated in renal impairment and sickle cell disease.
- Transdermal fentanyl is for stable chronic pain only, never for acute or opioid-naive patients. It takes 12 to 24 hours to reach effect, so provide alternative analgesia during titration; heat sources including fever, heating pads, and hot baths accelerate absorption and can cause overdose; and a removed patch still contains drug and must be folded adhesive-side-in and disposed of safely.
- Patient-controlled analgesia: only the patient presses the button. Family-administered dosing, sometimes called PCA by proxy, removes the built-in safety mechanism — a sedated patient cannot self-administer — and has caused fatal respiratory depression.
Non-pharmacological methods work best as adjuncts, not substitutes: positioning and immobilisation, heat and cold, massage, relaxation and guided imagery, distraction, music, transcutaneous electrical nerve stimulation, and the therapeutic presence of the nurse. Cutaneous stimulation and distraction are examples of the gate control mechanism, whereby competing sensory input reduces the transmission of pain signals.
Palliative Care Principles
Palliative care is not the same as end-of-life care. It is specialist symptom-focused care that is appropriate from diagnosis onward, alongside curative treatment, for anyone with a serious illness. Hospice care is the subset delivered when life expectancy is short and the focus has moved fully to comfort.
Core symptom management at the end of life:
- Dyspnoea: low-dose opioids are the most effective treatment, with a fan directed at the face, upright positioning, and reassurance. Oxygen helps only if the patient is hypoxaemic.
- Respiratory secretions ("death rattle"): reposition, stop unnecessary fluids, use antimuscarinic agents, and — critically — explain to the family that this distresses observers far more than the patient. Deep suctioning is distressing and ineffective.
- Nausea: match the antiemetic to the mechanism rather than reaching reflexively for one agent.
- Mouth care: the single most appreciated comfort measure; frequent moistening, lip balm, and oral hygiene.
- Terminal restlessness: search for reversible causes — urinary retention, constipation, pain, hypoxia — before sedating.
Recognising dying: increasing sleep and withdrawal, reduced oral intake, mottled cool extremities, a weak thready pulse, Cheyne-Stokes respiration, reduced urine output, and diminishing interest in surroundings. Hearing is believed to be among the last senses to fade, so continue to speak to the patient normally and encourage the family to do the same.
Ethical and Cultural Dimensions
The principle of double effect resolves a question candidates find uncomfortable: giving an opioid in a dose intended and titrated to relieve suffering is ethically and legally sound even if it may incidentally hasten death, provided the intent is symptom relief and the dose is proportionate. This is categorically different from administering a drug with the intent of causing death.
Grief is not a fixed sequence. Kübler-Ross's stages — denial, anger, bargaining, depression, acceptance — are widely taught but are not experienced in order or in full by most people, and normal anticipatory grief in families is expected rather than pathological.
Care after death in Qatar. Most patients and families are Muslim, and the expectations matter clinically. The body should be handled with modesty and respect and turned so the face is directed toward the Qiblah where feasible; only same-sex family members or designated people perform the ritual washing (Ghusl), and nursing staff should ask rather than assume which tasks the family wishes to perform. Burial is customarily prompt, usually within 24 hours, so documentation, certification, and release of the body must be handled without avoidable delay. Post-mortem examination and organ donation are sensitive topics requiring the involvement of the family and, where requested, religious guidance. For non-Muslim patients in Qatar's very diverse population, ask directly and early what the family's practices require, and record it in the care plan so that every shift can honour it.
