Management of Sickle Cell Crisis Without Acute Chest Syndrome
The management of sickle cell crisis without acute chest syndrome requires prompt pain control with opioid analgesics, aggressive hydration, oxygen therapy as needed, and prevention of complications through careful monitoring and supportive care. 1
Pain Management
- Patient-controlled analgesia (PCA) techniques are most effective for managing moderate to severe pain during vaso-occlusive crisis, with continuation of long-acting opioids if the patient is already taking them for chronic pain 1
- Pain should be assessed regularly using validated pain scales, with documentation of baseline analgesic use to guide therapy 1
- Multimodal analgesia including NSAIDs and adjuvant medications may be used alongside opioids for optimal pain control 1
Hydration Therapy
- Aggressive hydration is crucial as patients with sickle cell disease have impaired urinary concentrating ability and become dehydrated easily 1
- Oral hydration is preferred when possible, but intravenous fluids should be administered if oral intake is inadequate 1, 2
- For IV hydration, 5% dextrose solution or 5% dextrose in 25% normal saline is recommended rather than normal saline to avoid excessive sodium load due to hyposthenuria 3
- Meticulous fluid management with accurate measurement and replacement of fluid losses is essential, with careful monitoring of fluid balance to prevent overhydration 1
Oxygen Therapy
- Baseline oxygen saturation should be documented and monitored, with oxygen therapy administered to keep SpO2 above baseline or 96% (whichever is higher) 1
- Continuous oxygen monitoring is recommended until saturation is maintained at baseline in room air 1
- Avoiding hypoxia is crucial as it can precipitate further sickling 1
Temperature Management
- Patients should be kept normothermic as hypothermia can lead to shivering and peripheral stasis, increasing sickling 1
- Active warming measures should be employed if needed, with regular temperature monitoring 1
- A spike in temperature may be an early sign of sickling or infection and should prompt immediate evaluation 1
Infection Prevention and Management
- Patients with sickle cell disease are more susceptible to infections, which can precipitate crises 1
- Blood cultures should be obtained if the patient becomes febrile, and antibiotics should be started promptly if temperature reaches ≥38.0°C or if there are signs of sepsis 1
- Intravenous cannula sites should be inspected regularly for phlebitis and removed immediately if there are signs of redness or swelling 4
Mobilization and Respiratory Care
- Early mobilization should be encouraged to prevent complications like deep vein thrombosis 1
- Chest physiotherapy and incentive spirometry every 2 hours are recommended to prevent development of acute chest syndrome 1
- Bronchodilator therapy should be considered for patients with a history of small airways obstruction or asthma 4
Thromboprophylaxis
- All post-pubertal patients should receive thromboprophylaxis as they have an increased risk of deep vein thrombosis 1
- Additional precautions may be needed for patients with risk factors such as immobility or previous venous thromboembolism 4
Monitoring for Complications
- Regular assessment by hematology specialists is recommended for patients with moderate to severe crises 1
- A high index of suspicion should be maintained for acute chest syndrome, which can develop rapidly and is a leading cause of death among patients with sickle cell disease 5, 6
- Patients with acute life-threatening complications should be admitted to intensive care, and exchange transfusion may be necessary in severe cases 1
Multidisciplinary Approach
- Care should involve hematologists, pain specialists, and other relevant specialists working in partnership with patients and their families 1
- Individual care plans agreed between patient and treating specialist can improve patient experience and outcomes 7
- Specialized units away from the emergency department, where expert care can be delivered in a more compassionate environment, may improve outcomes 7
