Acute Abdomen
1. Trauma
A. Motor vehicle collisions, falls, child abuse
2. Appendicitis
A. Most predictive: RLQ pain, abd. wall rigidity, and migration of periumbilical pain to the RLQ
B.
Pediatric Appendicitis Score (PAS)
1. For 1-17 y/o, total 10 pts
2. Point System:
a. 2 pts: cough/percussion/hopping tenderness; RLQ tenderness;
b. 1 point: fever > 38° C, anorexia, N/V, migration of pain, WBC >10 000 cells/mm3 , and PMN >7500 cells/mm3
3. Score
PAS≧ 7: dx of appendicitis
PAS 3-6: Need image studies
PAS≦ 2: exclusion
(Reference:
