Study Notes
Shock in Pediatric Patients
- Shock occurs when the circulatory system can't deliver sufficient blood and oxygen to organs.
- Children can compensate for shock longer than adults but can quickly deteriorate to cardiopulmonary arrest.
- Common causes include hypovolemia, sepsis, allergic reactions, and poisonings; primary cardiac events are rare in pediatrics.
- Greater than 25% blood volume loss significantly increases the risk of shock.
- Symptoms similar to adults: tachycardia, changes in mental status, poor capillary refill time.
Assessment and Treatment of Shock
- Initiate treatment by assessing ABCDE (Airway, Breathing, Circulation, Disability, Exposure).
- In cases of suspected cardiac ARS, follow CAB (Compression, Airway, Breathing).
- Monitor for vital signs like pulse rate (over 160 beats/min indicates shock), skin signs (pale, cool, clammy), and capillary refill time.
- Blood pressure measurement can be challenging; values are age-specific.
- Look for specific signs: decreased urine output, absence of tears, sunken fontanel, changes in consciousness.
Anaphylaxis
- Major allergic reaction characterized by a systemic response to an antigen.
- Common triggers include insect stings, medications, and food allergies.
- Signs include hypoperfusion, stridor/wheezing, increased work of breathing, altered appearance, agitation, and hives.
- Treatment involves maintaining oxygen delivery, letting caregivers assist in positioning, and administering IV or IO access.
Bleeding Disorders
- Hemophilia is a hereditary condition affecting blood coagulation, predominantly in males.
- Immediate transport for affected patients is critical; do not delay tourniquet application for life-threatening bleeding.
- IV therapy may not be performed as frequently in children but follows adult protocols for indications and techniques.
Intravenous and Intraosseous Access
- IV catheter sizes vary by age (20-26 gauge generally suitable for pediatrics).
- Butterfly catheters may be useful; however, they have a higher rate of infiltration.
- Use micro drip sets (60 drops/mL) for fluid control.
- IO access is indicated if IV access is unsuccessful after three attempts or 90 seconds in critical patients; usually done in the proximal tibia.
Fluid Management
- Fluid resuscitation for shock initiates with a bolus of 20 mL/kg.
- Careful reassessment is necessary to prevent fluid overload or insufficient volume treatment.
Altered Mental Status
- Common causes include hypoglycemia, hypoxia, seizures, and drug/alcohol ingestion.
- Signs of altered mental status range from confusion to coma.
- Use the AEIOU TIPS mnemonic to evaluate potential causes.
Seizures in Pediatrics
- Seizures can result from various factors, including fever (febrile seizures) and head trauma.
- Recognizable symptoms vary; seizures in infants may be subtle.
- Status epilepticus is defined by repeated seizures or prolonged seizures over 30 minutes.
- Ensure airway protection, clear the mouth, and position appropriately.
Meningitis
- Inflammation of the meninges, often a serious infection risk.
- Symptoms include fever, headache, and altered consciousness; unique symptoms in infants include a high-pitched cry and apnea.
- Use caution as meningitis can be contagious; apply standard precautions.
Gastrointestinal Emergencies
- Symptoms can be vague; monitor for signs of shock with abdominal injuries.
- Appendicitis may lead to peritonitis if untreated; signs include fever and rebound tenderness.
- Assess hydration status based on urine output and ability to tolerate fluids.
Poisoning
- Common in children due to accidental ingestion or exposure; can vary in severity based on the toxic substance.
- Treatment includes external decontamination and maintaining ABCs; consider activated charcoal if protocol permits.
- Always assess the substance, dosage, and change in behavior.
Dehydration and Fever
- Vomiting and diarrhea are common causes of dehydration, which can lead to shock.
- Fever is typically a response to infection, with a threshold of 100.4°F or higher being abnormal.
- Signs of severe dehydration include altered mental status, tachycardia, and dry mucosal membranes.
Hypoglycemic and Hyperglycemic Emergencies
- Hypoglycemia: Symptoms include hunger, tremors, and altered mental state; treat with oral glucose if responsive or IV glucose if not.
- Hyperglycemia: May indicate new-onset diabetes or a missed insulin dose; can cause severe dehydration and diabetic ketoacidosis (DKA).
- Always monitor glucose levels and administer insulin as indicated based on local protocols.
Shock in Pediatric Patients
- Shock occurs due to inadequate blood and oxygen delivery to organs.
- Children can tolerate shock longer than adults but may rapidly progress to cardiopulmonary arrest.
- Most common causes: hypovolemia, sepsis, allergic reactions, poisonings; primary cardiac issues are rare in pediatric cases.
- More than 25% loss of blood volume significantly heightens shock risk.
- Symptoms include tachycardia, altered mental status, and poor capillary refill.
Assessment and Treatment of Shock
- Treatment begins with assessing ABCDE (Airway, Breathing, Circulation, Disability, Exposure).
- In suspected cardiac arrest, follow CAB (Compression, Airway, Breathing).
- Monitor vital signs: pulse over 160 beats/min indicates shock, with skin appearing pale, cool, and clammy.
- Blood pressure values are age-specific; direct measurement can be challenging in children.
- Look for signs: decreased urine output, absence of tears, sunken fontanel, altered consciousness.
Anaphylaxis
- Defined as a severe systemic allergic reaction.
- Common triggers: insect stings, medications, food allergies.
- Signs include hypoperfusion, stridor or wheezing, agitation, hives, and altered appearance.
- Treatment focuses on oxygen delivery, caregiver support for positioning, and establishing IV or IO access.
Bleeding Disorders
- Hemophilia is a hereditary disorder affecting blood coagulation, more common in males.
- Immediate transport for patients with hemophilia is crucial; apply tourniquet without delay for life-threatening bleeding.
- IV therapy in children follows adult protocols but may not be performed as frequently.
Intravenous and Intraosseous Access
- IV catheter sizes range from 20-26 gauge for pediatric use.
- Butterfly catheters can be effective but have a higher risk of infiltration.
- Use micro drip sets (60 drops/mL) for better fluid control.
- IO access is warranted if IV attempts fail after three tries or 90 seconds; usually accessed in the proximal tibia.
Fluid Management
- Initial fluid resuscitation for shock begins with a 20 mL/kg bolus.
- Continuous reassessment is necessary to avoid fluid overload or inadequate volume.
Altered Mental Status
- Common factors causing altered mental status include hypoglycemia, hypoxia, seizures, drug or alcohol ingestion.
- Symptoms can range from confusion to coma; use AEIOU TIPS mnemonic for evaluation.
Seizures in Pediatrics
- Seizures may be triggered by fever (febrile seizures) or head trauma.
- Symptoms manifest differently; seizures in infants may be subtle and less recognizable.
- Status epilepticus is identified by seizures lasting over 30 minutes or repeated episodes.
- Prioritize airway protection and positioning during seizures.
Meningitis
- Inflammation of the meninges poses serious infection risks.
- Symptoms: fever, headache, altered consciousness; unique infant signs include high-pitched cry and apnea.
- Meningitis can be contagious; standard precautions are recommended.
Gastrointestinal Emergencies
- Symptoms can be ambiguous; watch for shock signs with abdominal injuries.
- Appendicitis may progress to peritonitis if untreated; signs include fever and rebound tenderness.
- Assess hydration based on urine output and fluid tolerance.
Poisoning
- Common in children due to accidents; severity varies by substance.
- Treatment includes external decontamination and maintaining ABCs; activated charcoal may be administered following protocol.
- Always evaluate the substance, dosage, and any behavioral changes.
Dehydration and Fever
- Vomiting and diarrhea frequently lead to dehydration, which can result in shock.
- Fever typically signals infection; a reading of 100.4°F or higher is abnormal.
- Severe dehydration indications include altered mental status, tachycardia, and dry mucosal membranes.
Hypoglycemic and Hyperglycemic Emergencies
- Hypoglycemia: Symptoms are hunger, tremors, altered mental state; treat with oral glucose if responsive or IV glucose if not.
- Hyperglycemia: Indicates potential new-onset diabetes or missed insulin; can lead to severe dehydration and diabetic ketoacidosis (DKA).
- Regularly monitor glucose levels and administer insulin following local protocols.
