1. $10\text{ ml}$ of gross blood on aspiration
2. W.B.C. count more than $500/\text{cu mm}$
3. Amylase level more than $175\text{ IU/dL}$
4. R.B.C. count more than $100,000/\text{cu mm}$
The criteria for a positive DPL are :
Diagnostic Peritoneal Lavage (DPL) Positive Criteria
Diagnostic Peritoneal Lavage (DPL) is a procedure used to detect internal bleeding or injuries in the abdomen following trauma. Interpreting the characteristics of the fluid retrieved is crucial for diagnosis.
Evaluating DPL Findings in Trauma
Several findings from the DPL fluid indicate a positive result, suggesting significant intra-abdominal injury:
- Gross Blood: The presence of $10\text{ ml}$ or more of gross blood upon initial aspiration is a definitive sign of substantial hemorrhage.
- W.B.C. Count: A White Blood Cell (W.B.C.) count exceeding $500/\text{cu mm}$ in the lavage fluid suggests inflammation or peritonitis, often resulting from organ damage or perforation.
- Amylase Level: An elevated amylase level, measured at more than $175\text{ IU/dL}$, can indicate pancreatic injury or other gastrointestinal tract damage.
- R.B.C. Count: A Red Blood Cell (R.B.C.) count greater than $100,000/\text{cu mm}$ is considered another indicator of significant internal bleeding into the peritoneal cavity.
In the context of abdominal trauma assessment using DPL, all four listed findings (gross blood, elevated W.B.C. count, elevated amylase level, and elevated R.B.C. count) represent criteria for a positive DPL result, necessitating further medical intervention.
Important Questions from Abdominal Injuries
- Which of the following statements regarding a patient of liver trauma are correct?
1. Liver is the most common organ injured following abdominal trauma.
2. Surgical exploration (laparotomy) is required in haemodynamically unstable patients and patients with free intraperitoneal fluid on FAST.
3. Contrast enhanced CT abdomen should be done in haemodynamically stable patients.
4. Blunt injuries have a higher mortality as compared to penetrating injuries.
Select the correct answer using the code given below. - Diaphragmatic injury is suspected in a 50 year gentleman with history of blunt abdominal trauma, having a normal chest X-ray. He is best managed by:
- Mainstay of an accurate diagnosis of pancreatic injury following blunt abdominal trauma is:
- A 30-year-old patient developed haematuria following a blunt injury to the abdomen. The patient is haemodynamically stable. However, the ultrasonographic examination reveals a perirenal collection which measures 4 x 4 cm. The patient is best managed by
- What is the investigation of choice in a patient with blunt abdominal trauma with hematuria?
