When would diagnostic peritoneal lavage be considered in current ATCN practice?

• A. When FAST is inconclusive or unavailable and rapid intra-abdominal bleeding must be ruled in/out, or in resource-limited settings
• B. As first-line imaging before FAST
• C. Only after CT
• D. Never used

Answer: (A)

The main idea is that diagnostic peritoneal lavage is a rapid, bedside option when you need a quick answer about intra-abdominal bleeding and FAST either can’t give a clear result or isn’t available. In ATCN practice, FAST is the initial screening tool for suspected intra-abdominal hemorrhage. If the FAST exam is inconclusive or—due to equipment, trainer, or patient factors—it can’t be performed promptly, DPL serves as a salvage test to determine whether bleeding is present and whether urgent operative intervention is warranted. It’s also valuable in resource-limited settings where CT or reliable ultrasound access is not available, enabling a rapid decision about laparotomy. So, the best fit is using DPL when FAST is inconclusive or unavailable and rapid decision-making is needed, or in settings with limited resources. The other options aren’t as appropriate because DPL is not a routine first-line imaging step before FAST, it isn’t typically used after CT, and it isn’t unused in current practice.
