Continue readingThe Alvarado model is a clinical decision rule for diagnosing appendicitis. This model uses the MANTRELS mnemonic to examine 8 findings from the medical history or the examination, and the resulting score provides guidance on whether to operate in the setting of suspected appendicitis. Of 10 potential points, patients with a score of 7 or higher are considered “positive” and are more likely to have appendicitis. The various components are
Migration (1 point),
Anorexia-acetone (1),
Nausea-vomiting (1),
Tenderness in RLQ (2),
Rebound pain (1),
Elevation of temperature (1),
Leukocytosis (2), and
Shift to the left of normal WBC count (1). See
