Recovery Facilitation and Safe Transition of Care in Acute Ischemic Stroke
Learning Objective
Develop a plan to facilitate patient recovery, mitigate long-term complications, and ensure a safe transition of care in AIS survivors.
I. De-escalation of Intensive Therapies
As neurological stability is achieved, gradual weaning of vasopressors and ventilatory support minimizes ICU-related morbidity and accelerates rehabilitation.
A. Hemodynamic Support Weaning
Indications:
- Neurological improvement with stable MAP target (e.g., ≥65 mmHg or individualized goal)
- End-organ perfusion adequate (urine output >0.5 mL/kg/h, down-trending lactate)
Titration Protocol:
- Reduce vasopressor dose by 10–20% every 30–60 minutes
- Monitor for MAP < target; revert to prior dose if hypotension recurs
- Avoid abrupt cessation to prevent rebound hypotension
Monitoring:
- Continuous BP (invasive or noninvasive)
- Mental status, urine output, serum lactate clearance
Key Pearls: Hemodynamic Weaning
- Assess volume status before each decrease; consider 250–500 mL fluid bolus if indicated.
- Fludrocortisone (off-label) may aid refractory vasoplegia.
B. Ventilator Liberation
Early assessment and weaning reduce ventilator-associated complications and promote mobilization.
Readiness Criteria:
- Rapid Shallow Breathing Index (RSBI) <105 breaths/min/L
- Maximal inspiratory pressure (P0.1) <3.5 cm H2O
- Glasgow Coma Scale (GCS) ≥8 with ability to follow commands
Spontaneous Breathing Trial (SBT):
- 30–120 min on T-piece or minimal pressure support (PS)
- Watch for tachypnea, SpO2 <90%, tachycardia, hypertension
- If tolerated, coordinate extubation with multidisciplinary team
Sedation Interruption & Delirium Prevention:
- Daily sedation vacation
- Prefer dexmedetomidine or propofol over benzodiazepines
- Promote sleep hygiene, reorientation, early mobilization
Key Pearls: Ventilator Liberation
- Combine sedation hold with SBT for efficient assessment.
- In-bed mobilization even while ventilated shortens ICU stay.
II. Conversion from IV to Enteral Medications
Transition to enteral therapy supports discharge planning, lowers infection risk, and eases resource utilization.
A. Assess GI Function & Access
- Confirm bowel sounds, absence of ileus, tolerance of trophic feeds
- Verify secure NG or PEG tube placement in dysphagic patients
B. Formulation & Tube Compatibility
- Use liquids or crushable tablets; avoid extended-release (ER)/enteric-coated (EC) and sublingual forms unless validated
- Flush tube with 15–30 mL water before/after each drug
- Separate administration from continuous feeds when interactions known (e.g., phenytoin)
C. Dosing Equivalence & Absorption
- Warfarin: may crush tablet; monitor INR closely
- Phenytoin: reduced bioavailability with feeds; hold feeds 1–2 h pre/post dose
- DOACs: apixaban, rivaroxaban tablets can be crushed; avoid enteral nutrition for 2 h post-dose
D. Monitoring Effect & Adverse Events
- Track clinical endpoints (BP, platelet inhibition, glucose control)
- Check levels or anti-Xa/INR where applicable
Key Pearls: IV to Enteral Conversion
- Administer warfarin separate from feeding to optimize absorption.
- Reevaluate efficacy 24–48 h after conversion.
III. Prevention of Post-ICU Syndrome (PICS)
PICS encompasses physical, cognitive, and psychiatric sequelae; proactive, multidisciplinary care mitigates risks.
A. Risk Stratification
Factors increasing PICS risk include:
- Prolonged sedation (>48 h)
- Advanced age
- Sepsis
- Multi-organ failure
- Baseline cognitive impairment
B. ABCDEF Bundle
- A: Assess & manage pain (use Behavioral Pain Scale, multimodal analgesia)
- B: Both Spontaneous Awakening and Breathing Trials daily
- C: Choice of sedation—favor dexmedetomidine/propofol; minimize benzodiazepines
- D: Delirium monitoring (CAM-ICU) and management of reversible causes
- E: Early mobility—passive/active exercises as tolerated
- F: Family engagement in reorientation and care planning
Key Pearl: ABCDEF Bundle
Full bundle implementation reduces delirium incidence, ICU length of stay (LOS), and improves functional outcomes.
IV. Medication Reconciliation and Discharge Counseling
Meticulous reconciliation and patient education ensure adherence to secondary prevention and reduce readmissions.
A. Comprehensive Medication Review
Align pre-admission, ICU, and discharge lists; discontinue duplicates/unnecessary agents.
B. Secondary Prevention Pharmacotherapy
- Antithrombotic Agents
- Aspirin 81–325 mg PO daily (start 24–48 h post-stroke)
- Clopidogrel 75 mg PO daily; dual therapy for 21 days in minor stroke/TIA
- DOACs for Afib: apixaban 5 mg BID (adjust renal), rivaroxaban 20 mg daily; initiate 4–14 days post-event
- High-Intensity Statins
- Atorvastatin 40–80 mg or rosuvastatin 20–40 mg PO daily
- Antihypertensives
- Resume or initiate ACEI/ARB, thiazide, or CCB in stable patients with BP >140/90 mmHg
- Glycemic Control
- Transition from IV insulin to basal/bolus or oral agents; target 140–180 mg/dL
C. Patient & Caregiver Education
Teach drug indications, dosing, side effects; use teach-back and written materials.
D. Coordination & Follow-Up
Communicate changes to PCP/neurology; schedule outpatient visits within 1–2 weeks.
Key Pearl: Discharge Counseling
Structured discharge counseling reduces 30-day readmissions and improves adherence.
V. Pharmacotherapy Considerations
A. Vasopressors
| Agent | Mechanism | Dosage | Comments |
|---|---|---|---|
| Norepinephrine | α1 > β1 | 0.01–3 μg/kg/min | MAP ≥65 mmHg; preferred first-line |

VII. Pearls and Pitfalls
General Pearls:
- Taper vasopressors slowly; reassess volume status with each step to avoid hypotension.
- Coordinate sedation holds with Spontaneous Breathing Trials (SBTs) to optimize ventilator liberation and reduce ventilation duration.
- When converting IV to enteral, crush only formulations confirmed to be safe for crushing; monitor closely for changes in absorption and efficacy.
- Implement the full ABCDEF bundle consistently for the best outcomes in preventing PICS and improving patient recovery.
- Engage in multidisciplinary discharge planning involving pharmacy, nursing, physical/occupational therapy, and outpatient care teams to ensure a smooth transition.
Common Pitfalls:
- Abrupt cessation of vasopressors leading to rebound hypotension.
- Failure to assess and optimize volume status before vasopressor weaning.
- Prolonging mechanical ventilation due to uncoordinated weaning efforts or excessive sedation.
- Crushing extended-release or enteric-coated medications, leading to dose dumping or inactivation.
- Overlooking potential drug-nutrient interactions with enteral feeding (e.g., phenytoin, warfarin).
- Inconsistent application of the ABCDEF bundle components, diminishing its overall benefit.
- Inadequate patient and caregiver education at discharge, leading to medication errors or non-adherence.
- Poor communication between inpatient and outpatient providers during care transitions.
