EMT: Other Pediatric Emergencies Part 2
This lesson continues the discussion on various pediatric emergencies, focusing on hematologic, oncologic, and immunologic conditions. While some of these are less common, their high acuity requires EMTs to have a foundational understanding for early recognition and appropriate prehospital management.
Hematologic, Oncologic, and Immunologic Emergencies
These conditions can be complex and present with life-threatening complications. Pediatric patients with these issues often have compromised immune systems, making them vulnerable to severe infections.
1. Immunosuppression:
Causes: Congenital immune deficiencies, chemotherapy, chronic steroid use, HIV/AIDS.
Presentation: May appear severely ill, with rapid progression to shock from infections (e.g., sepsis). Subtle signs of infection can quickly become critical.
Special Considerations: Acute awareness for sepsis is paramount. Rapidly assess for signs of decompensation. Caregivers are vital sources of information regarding the child's baseline and specific vulnerabilities.
Management: Support ABCs. High-flow oxygen. Monitor vital signs closely. Early recognition of shock and aggressive fluid resuscitation (per protocol). Rapid transport to a specialized pediatric facility.
2. Sickle Cell Crisis:
Sickle cell disease is a genetic blood disorder common in certain ethnic populations. Patients can experience acute exacerbations known as crises.
Vaso-occlusive Crisis (Pain Crisis): Most common, caused by sickled cells blocking small blood vessels, leading to severe pain in bones, joints, and abdomen.
Acute Chest Syndrome: A life-threatening complication characterized by chest pain, fever, cough, tachypnea, and hypoxia. Can mimic pneumonia or pulmonary embolism.
Splenic Sequestration Crisis: Acute enlargement of the spleen with trapping of red blood cells, leading to hypovolemic shock. Most common in infants and young children.
Stroke: Can occur in children with sickle cell disease due to blockages in cerebral blood vessels.
Management:
Pain management is crucial (consider analgesics per protocol).
Supplemental oxygen to prevent further sickling.
Maintain hydration with oral or IV fluids (per protocol).
Rapid transport for definitive care.
3. Tumor Lysis Syndrome:
A potentially life-threatening complication of cancer treatment, especially in rapidly growing tumors. It results from the rapid breakdown of cancer cells, releasing their contents into the blood.
Complications: Severe electrolyte imbalances (hyperkalemia, hyperphosphatemia, hypocalcemia), hyperuricemia, acute kidney injury, cardiac arrhythmias.
Prehospital role: Recognize the risk in oncology patients, monitor cardiac rhythm, manage electrolytes (ALS per protocol), and ensure rapid transport.
4. Bleeding Disorders (e.g., Von Willebrand Disease, Hemophilia):
Von Willebrand Disease: The most common inherited bleeding disorder, affecting platelet adhesion. Patients may present with easy bruising, nosebleeds, or prolonged bleeding after injury.
Hemophilia: A group of inherited disorders where blood doesn't clot properly due to a lack of clotting factors. Patients are at risk for spontaneous bleeding or severe hemorrhage after minor trauma.
Management: Direct pressure for external bleeding. Maintain airway, breathing, circulation. Treat for shock if signs present. Rapid transport.
General Considerations for Children with Indwelling Catheters or Devices
Children with chronic medical conditions often have indwelling catheters (e.g., central lines, peritoneal dialysis catheters) or other devices.
Assessment: Evaluate the catheter site for erythema (redness), swelling, tenderness, or purulent discharge, which can indicate a serious infection.
Caregivers: Are often experts in managing these devices and can provide crucial information.
Critical Thinking Questions
You are called to a 7-year-old child with sickle cell disease complaining of severe bone pain and difficulty breathing. What are your immediate concerns, and how would your prehospital management address both pain and potential respiratory compromise?
A pediatric oncology patient undergoing chemotherapy presents with altered mental status and cardiac arrhythmias. What serious complication might you suspect, and what is the underlying physiological cause?
Explain why children with immunosuppression are particularly vulnerable to rapid deterioration from seemingly minor infections.
You are treating a child with a known history of hemophilia who sustained a minor laceration and is bleeding excessively. Beyond direct pressure, what other considerations are crucial for this patient's prehospital care?
Discuss the role of the caregiver in managing pediatric patients with complex medical histories and indwelling devices in the prehospital setting.
