Q: What is Carnett's sign?
Answer: Carnett's sign is an easy to do bedside exam in 5 seconds. It may provide significant clinical clues. This maneuver is performed in patients with acute abdominal pain to differentiate between intraabdominal pathology (like appendicitis) or abdominal wall pathology (like rectus sheath hematoma or hernia).
During the exam, the patient is asked to lift the head and shoulders from the supine position or to raise both legs with straight knees - to tense the abdominal muscles. If pain increase in intensity, the abdominal wall is the likely source of pain and if the abdominal pain decreases, an intra-abdominal pathology of the pain is likely
