2.4 Positioning, Injury Prevention, Recovery, and Discharge Teaching
Key Takeaways
- Positioning injury prevention includes pressure protection, nerve protection, thermal safety, eye protection, secure extremities, and removal or control of extraneous objects.
- Recovery from anesthesia is judged by airway, ventilation, circulation, level of consciousness, pain, nausea, temperature, mobility, surgical site status, and return toward baseline.
- Discharge after blocks requires teaching about numbness, weakness, limb protection, fall prevention, pain medication timing, and when to call for help.
- Discharge after sedation requires a responsible adult, no driving or legal decisions, continued observation, and clear escalation instructions for respiratory, bleeding, pain, nausea, or neurologic concerns.
Injury prevention starts before recovery
The anesthesia domain includes protecting the patient from injury caused by positioning, thermal sources, and extraneous objects. This is especially important because anesthetized or sedated patients cannot reliably report pressure, stretching, heat, cold, moisture, or eye irritation.
Positioning risks by mechanism
| Risk | Examples | Nursing prevention |
|---|---|---|
| Pressure injury | Sacrum, heels, elbows, occiput, ears under straps or oxygen tubing | Pad pressure points, check tubing and devices, avoid wrinkles and hard edges. |
| Nerve injury | Ulnar nerve at elbow, brachial plexus stretch, peroneal nerve at fibular head | Keep alignment neutral, avoid extreme abduction, pad vulnerable areas. |
| Thermal injury | Forced-air warming misuse, prep solution pooling, hot packs, cold packs | Follow device instructions, keep skin dry, avoid direct heat/cold on insensate areas. |
| Eye injury | Corneal abrasion, pressure on eye during prone or lateral positioning | Protect eyes after loss of reflexes; check that nothing presses on the orbit. |
| Circulatory compromise | Tight straps, dependent limb swelling, compression from equipment | Assess color, temperature, pulses, capillary refill, and device fit. |
| Foreign object injury | ECG leads, clamps, jewelry, dentures, hairpins, monitoring cables | Remove or secure items; check skin after transfer and procedure. |
The exam may ask about a numb arm after a block or an anesthetized extremity near a heat source. The correct answer is usually protective: support the limb, avoid pressure, avoid heat or cold, and teach the patient not to use the extremity until sensation and strength return.
Recovery from anesthesia
Recovery is not a single event. The patient must emerge from anesthetic and sedative effects while maintaining oxygenation, perfusion, neurologic function, comfort, temperature, and surgical-site stability.
High-yield recovery assessments include:
- Airway patency, respiratory rate, work of breathing, oxygen saturation, and use of oxygen or CPAP.
- Level of consciousness compared with expected emergence and baseline cognition.
- Blood pressure, heart rate, rhythm concerns, perfusion, and bleeding.
- Pain score, nausea/vomiting, shivering, pruritus, and urinary retention when relevant.
- Motor and sensory function after regional or neuraxial anesthesia.
- Temperature and warming response.
- Surgical dressing, drainage, and procedure-specific restrictions.
A patient who is awake but weak after neuromuscular blockade, alert but hypoxic after opioids, pain-free but unable to bear weight after a block, or cheerful but alone after sedation is not discharge-ready.
Discharge teaching after peripheral nerve blocks
Blocks are a major ambulatory advantage, but they move risk into the home. Teaching should be concrete and repeated with the responsible adult present.
Essential block instructions:
- Protect the numb limb from heat, cold, pressure, and sharp objects.
- Use slings, braces, crutches, walkers, or immobilizers exactly as instructed.
- Do not bear weight on a blocked leg until cleared and strength has returned.
- Begin prescribed oral pain medication before the block fully wears off if instructed, rather than waiting for severe pain.
- Expect gradual return of tingling and discomfort, but call for severe unrelieved pain, persistent complete numbness beyond the expected window, new swelling, color change, or inability to move after the expected duration.
- Keep the limb positioned safely during sleep and transport.
For upper-extremity blocks, remind the patient not to cook, handle hot beverages, use power tools, or rest the arm against hard surfaces while numb. For lower-extremity blocks, fall prevention is the priority: assistance with transfers, no stairs without help if restricted, and no driving until cleared.
Discharge teaching after sedation or general anesthesia
Sedation discharge teaching focuses on delayed psychomotor impairment and recurrent respiratory depression. The patient may feel normal before judgment, coordination, and reaction time are safe.
Standard teaching includes:
- A responsible adult must drive the patient home and stay as directed by facility policy and provider instructions.
- No driving, alcohol, sedatives not approved by the care team, machinery, major decisions, or legal documents for the specified period.
- Take pain and nausea medications as directed; avoid combining opioids with alcohol or unapproved sedatives.
- Call for difficulty breathing, persistent excessive sleepiness, repeated vomiting, uncontrolled pain, heavy bleeding, chest pain, fever as defined in instructions, or new neurologic symptoms.
- Follow procedure-specific instructions for diet, activity, wound care, and follow-up.
Ophthalmic and topical anesthesia discharge considerations
After ophthalmic procedures, the patient may have blurred vision, patching or shield instructions, restrictions on bending or lifting, and a strong need to avoid rubbing the eye. If topical anesthesia and light sedation were used, the nurse should still provide sedation precautions when IV sedatives or opioids were administered.
During recovery, new eye pain, sudden vision change, severe headache, nausea with eye pressure concern, or inability to follow protective instructions should be escalated. Home teaching should be simple, specific, and verified with the caregiver.
Phase-appropriate readiness
Many facilities use scoring systems, but CAPA questions usually describe the underlying criteria. Look for stable vital signs, patent airway, adequate oxygenation, baseline or acceptable mental status, controlled pain and nausea, minimal bleeding, safe mobility plan, voiding if required by procedure or neuraxial anesthesia policy, and patient/caregiver understanding.
The nurse should delay discharge when a patient has repeated desaturation, uncontrolled vomiting, escalating pain, new neurologic deficit, unresolved motor block that makes transfers unsafe, no responsible adult after sedation, or instructions the patient and caregiver cannot repeat accurately.
Final exam lens
For anesthesia recovery and discharge items, avoid answers that focus only on speed. Ambulatory care values efficiency, but the CAPA standard is safe efficiency. Choose the intervention that prevents foreseeable harm after the patient leaves the monitored setting.
