History Taking in Pediatric Abdominal Cases
Introduction to Pediatric Abdominal History Taking
Taking a thorough history is crucial in pediatric abdominal cases. It requires a systematic approach tailored to the child's age and developmental stage. The clinician must gather information from both the patient and caregivers, paying attention to verbal and non-verbal cues. Key components include:
- Establishing rapport with the child and family
- Using age-appropriate language and techniques
- Observing the child's behavior and interactions
- Balancing direct questions with open-ended inquiries
- Considering psychosocial factors that may influence the presentation
Remember, the history should guide the physical examination and inform the differential diagnosis.
Chief Complaint
The chief complaint is the primary reason for seeking medical attention. In pediatric abdominal cases, common chief complaints include:
It's important to document the chief complaint in the patient's (or caregiver's) own words. For non-verbal children, observe for signs of discomfort or changes in behavior.
History of Present Illness
The history of present illness (HPI) provides a detailed account of the current problem. Use the OLD CARTS mnemonic to guide your questioning:
- Onset: When did the symptoms start?
- Location: Where is the pain or discomfort?
- Duration: How long have the symptoms persisted?
- Character: What does the pain feel like?
- Aggravating factors: What makes the symptoms worse?
- Relieving factors: What makes the symptoms better?
- Timing: Is there a pattern to the symptoms?
- Severity: How intense is the pain or discomfort?
For abdominal cases, also inquire about:
- Changes in appetite or weight
- Bowel habits and stool characteristics
- Urinary symptoms
- Recent illnesses or exposures
- Dietary changes or new foods introduced
