All of the following are suggestive of positive DPL except:: (A) >10 mL of gross blood is aspirated directly from peritoneal cavity, (B) Effluent contains RBCs >1 lac/mm3, (C) Effluent contains Amylase >174 IU/dL, (D) WBC >100/mm3
Answer is D. DIAGNOSTIC PERITONEAL LAVAGE: - Performed for blunt trauma abdomen patients - DPL is performed through veical infra-umbilical midline incision unless the patients has pelvic fracture or is pregnant Positive DPL - > 10 mL of gross blood is aspirated directly from peritoneal cavity - Returned effluent contains - RBCs > 1 lac/ mm3 - WBCs > 500 / mm3 - Demonstrable bacteria or bile - Amylase > 174 IU/ dL - Sensitivity of DPL for detecting significant intra-abdominal injury is 82-96% & specificity 87-99%
