This document discusses diaphragmatic injuries, their causes, signs and symptoms, diagnosis, and management. Diaphragmatic injuries occur most often from penetrating trauma (65%) or blunt trauma (35%) to the abdomen or chest. Associated injuries to other organs are common, occurring in 80-100% of diaphragmatic injury cases. Diagnosis can be made through chest x-rays, ultrasound, CT scans, or laparoscopy, with CT scans having high sensitivity and specificity. Management involves surgical exploration and repair of the diaphragm, often through laparotomy. Complications can include herniation of abdominal organs into the chest if left untreated.

🞭 Nonvisualized diaphragm

15. DPL
🞭 To improve its sensitivity for diagnosing
diaphragmatic injuries in penetrating
thoracoabdominal trauma, many clinicians
have modified the red blood count (RBC)
criteria, accepting lower RBC counts
(>10,000/mm3) to decrease the rate of false
negative results.

16. CT
🞭 Discontinuity of the diaphragm
🞭 Herniation of the abdominal contents into the chest
🞭 Abnormal positioning of a nasogastric tube
🞭 Waist-like constriction of bowel
🞭 Viscera (liver, stomach) are in direct contact with the
posterior ribs
🞭 Contiguous injury from one side of the diaphragm to
the other (ie, left pulmonary laceration and splenic
laceration)
🞭 Sensitivity 82-87 % Specificity 72-99 % - in blunt
abdominal injury
