INITIAL  ASSESSMENT AND FOCUSED HISTORY AND DETAILED PHYSICAL

EXAMINATION FOR NON-TRAUMATIC ABDOMINAL EMERGENCIES

 

 

1).  Assess environment:  (may need to manipulate the environment)

·        Safety of rescuers and environment

  • Environmental factors
    • Medications (may offer clues to past medical history)
    • Witnesses (may help to explain circumstances)

 

3).  Breathing:  assess the rate and quality of respirations

 

5). Skin signs:  assess color, temperature and moisture

  • Pale, cool, moist skin and delayed capillary refill are due to peripheral vasoconstriction
  • If signs of poor perfusion, consider placing patient supine
 

7).  Determine chief complaint:

 

4).  Circulation:  palpate for pulse noting rate/rhythm/quality

 

2).  Airway:   determine responsiveness and patency of airway

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

FOCUSED HISTORY AND DETAILED PHYSICAL EXAMINATION

 

6).  Assess Neurological Status:  

  • Assess level of consciousness using the GCS, and neuro deficits
 

3).  Vital Signs

  • Blood pressure—not a reliable early indicator of shock; assess for more subtle signs (capillary refill, heart rate, altered LOC)
  • Orthostatic vital signs if indicated
  • Pulse—rate and quality
  • Respirations—rate, depth, tidal volume, and lung sounds (present, absent, or abnormal)
  • Pupils—(pupillary size and reaction to light)
 

1).  Elicit history of chief complaint or problem  (PQRST)

  • P         provoking factor
  • Q         quality of pain
  • R         radiation or region
  • S         severity
  • T          time of onset
 

4).  Special Questions

Ask questions specific to chief complaint:

  • Nausea/vomiting
  • Diarrhea/constipation
  • Hematuria
  • Melena
  • Anorexia
  • Fever
  • Weakness/syncope
 

2).  Elicit personal history (HAM)

  • H   medical history/under a doctors care
  • A   allergies/age
  • M   medications-current over the counter and prescription
 

5).  Pertinent Body Check:

  • Medical or minor trauma—perform body check pertinent to chief complaint
