Study Notes
McBurney Point
- Located two-thirds the distance from the umbilicus to the anterosuperior iliac spine.
Key Signs in Appendicitis
- Rovsing Sign: Referred tenderness from the left lower quadrant (LLQ) to the right lower quadrant (RLQ) during palpation.
- Psoas Sign: Pain elicited by extending the hip when the patient lies prone.
- Obturator Sign: Pain elicited by abducting the right hip with the patient in a supine position.
Diagnostic Signs for Appendicitis
- Signs that reliably indicate acute appendicitis in children include:
- Absent or decreased bowel sounds.
- Positive psoas, obturator, and Rovsing signs.
Appendicitis Inflammatory Response
- Fewer symptoms compared to the Alvarado score and Pediatric Appendicitis Score.
- Incorporates C-reactive protein (CRP) as an inflammatory biomarker.
- Assesses severity of rebound pain, leukocytosis, and polymorphonuclear cells.
Eliciting Signs
- Psoas Sign: Pain occurs on passive extension of the right thigh while the patient lies on the left side.
- Obturator Sign: Pain occurs on passive internal rotation of the flexed thigh.
Demographics and Imaging
- Overweight and obese individuals are more likely to undergo CT scans due to nondiagnostic results from ultrasonography.
Alvarado Score Criteria
- Total criteria include 8 indicators, scoring as follows:
- Migration of pain (1)
- Anorexia (1)
- Nausea/vomiting (1)
- Right lower quadrant tenderness (2)
- Rebound pain (1)
- Temperature ≥ 37.3°C (99.1°F) (1)
- Leukocytosis ≥ 10,000 per µL (2)
- PMN ≥ 75% (1)
- Possible total score is 10.
Pediatric Appendicitis Score
- Adds an assessment for right lower quadrant pain during coughing, hopping, or percussion.
Risk Scoring System
- Alvarado score risk categories:
- High risk: score ≥ 7
- Moderate risk: score 4 to 6
- Low risk: score < 4
Complications of Appendicitis
- Most concerning complication is perforation, which can lead to abscesses, peritonitis, bowel obstruction, fertility issues, and sepsis.
Signs and Symptoms in Appendicitis
-
In Adults:
- Right lower quadrant pain.
- Abdominal rigidity.
- Radiation of periumbilical pain to RLQ.
-
In Children:
- Absent or decreased bowel sounds.
- Positive psoas, obturator, and Rovsing signs.
Evaluation Tools
- Adults: Alvarado score.
- Pediatrics: Pediatric Appendicitis score.
Summary of Alvarado Score Components
- M: Migration of pain (1)
- A: Anorexia (1)
- N: Nausea (1)
- T: Right lower quadrant tenderness (2)
- R: Rebound pain (1)
- E: Elevated temperature (1)
- L: Leukocytosis (2)
- S: Shift to the left (1)
