Study Notes
Cyanosis in Children
- History: Cyanosis is a bluish discoloration of the skin, lips, mucous membranes, or nailbeds. Assess the onset (sudden or gradual), duration, timing, body location, and frequency.
- Associated Symptoms: Consider dyspnea, cough, wheezing, stridor, fever, excessive crying, and factors that trigger or relieve symptoms.
- Past History: Evaluate maternal factors like diabetes, drug use, pregnancy complications (polyhydramnios, oligohydramnios, meconium-stained amniotic fluid), and birth history. Also note past medical history, including congenital heart disease, lung disease, or neurological conditions.
- Medication History: Inquire about recent medications, especially those that might cause methemoglobinemia—antibiotics, sulphonamides, or antimalarials.
- Developmental History: Assess normal developmental and growth milestones.
- Feeding History: Note any difficulties with feeding, rapid breathing, or excessive sweating during feedings.
- Family History: Check for a family history of asthma, hemoglobinopathy, congenital heart disease, or birth defects.
- Social History: Assess contact with infectious diseases, exposure to toxins (oxidants or smoke), or severe cold exposure.
- Newborn Considerations: Maternal diabetes, polyhydramnios, oligohydramnios, meconium aspiration, and persistent pulmonary hypertension are potential risks.
- Older Children Considerations: Congenital heart disease, primary lung disease, pulmonary artery hypertension, or abnormal hemoglobin are possible causes of persistent cyanosis. Cyanotic breath-holding spells (or Tet spells) might be linked to crying followed by sudden breath-holding during forced expiration (often in the morning).
Abdominal Pain and Diarrhea
- Surgical causes of bloody diarrhea: Issues such as intussusception, anal fissures, and hemorrhoids are possible causes.
- Constipation and rectal bleeding: Significant rectal bleeding often accompanies constipation.
- Abdominal trauma cases: Ask about the mechanism of injury; possible blunt or penetrating trauma and loss of consciousness following a car accident should be noted.
Rectal Bleeding
- Severity of bleeding: Assess the presence and amount of blood, frequency of episodes, and whether it's mixed with diarrhea or mucus.
- Associated symptoms: Consider the presence of diarrhea, mucus, or abdominal pain.
- Past medical history: Note any conditions such as inflammatory bowel disease, infections, or coagulation disorders.
- Timing of bleeding: Determine if bleeding occurs before or after defecation for diagnostic clues, distinguishing between possible causes such as an anal fissure (before) versus hemorrhoids (after).
