In an effort to refine the diagnostic value of dpl, attention was directed toward microscopic examination of lavage fluid. The best criteria for bt were as follows: The remaining 85 patients with negative dpl based on the wbc criterion.

All three of these exams have advantages and disadvantages and.
Diagnostic peritoneal lavage criteria for emergency room discharge j trauma.
Utilizing a qualitative colorometric method to evaluate the degree of hemoperitoneum, patients could. Figure 16.1 anatomical landmarks for diagnostic peritoneal lavage. Diagnostic peritoneal lavage in blunt abdominal trauma. Methods fifty victims with physical examinations and/or computed tomography findings equivocal for blunt hollow visceral injury underwent dpl.
A diagnostic peritoneal lavage (dpl) using otomo’s criteria and cell count ratio is highly predictive of the presence of blunt hollow visceral injury in a patient with pneumothorax or ventilated patient with absence of peritonism, and recommended after ct scan of abdomen.
Hemodynamically stable patients with negative physical examinations were entered in the study and evaluated with closed diagnostic peritoneal lavage (dpl). By determining the site and extent of abdominal solid organ injuries by computed tomography (ct) and. Diagnostic peritoneal aspirate and lavage is a rapid and easily performed but invasive bedside procedure that was once the gold standard for the evaluation of abdominal trauma [ 1 ]. At one time, diagnostic peritoneal lavage (dpl), described by root in 1965, [ 1] was the diagnostic test of choice for detecting bleeding within the.
Place a nasogastric tube (unless contraindicated) to suction to decompress the stomach.
First, the clinician attempts to aspirate free intraperitoneal blood. The lavage is positive if there are > 100,000 red blood cells/ml, > 500 white blood cells/ml, or a positive gram stain test. To test the usefulness of diagnostic peritoneal lavage (dpl) for identifying blunt hollow visceral injury with two different sets of criteria or a combination of the two. Diagnostic peritoneal lavage (dpl) is a highly accurate test for evaluating intraperitoneal hemorrhage or a ruptured hollow viscus, but is performed less frequently today due to the increased use of focused abdominal sonography for trauma (fast) and helical computed tomography (ct).
Download table | criteria for positive finding on diagnostic peritoneal lavage (7) from publication:
And negative, lrbcs less than 50,000/mm3 and lwbcs less than 100/mm3. Diagnostic peritoneal lavage (dpl) is a highly accurate test for evaluating intraperitoneal hemorrhage or a ruptured hollow viscus, but is performed less frequently today due to the increased use of focused abdominal sonography for trauma (fast) and helical computed tomography (ct). Because it may be performed faster, closed dpl is recommended with conversion to open technique if complications occur. If 10 ml or more of blood is aspirated, the procedure stops because intraperitoneal injury is likely.
Consent was obtained for all patients before study entry.
Anatomic boundaries for abdominal stab wounds were costal margins, inguinal ligaments, and anterior axillary lines. Evaluating the positive predictive value of. As a result of recent advances in radiological diagnostic procedures, traumatic hemoperitoneum is no longer an absolute indication for emergency laparotomy. Ultrasound (us) is highly sensitive in identifying >200 ml of intraperitoneal fluid.
In 133 patients with hemoperitoneum, emergency celiotomy was performed in only 48;
Open dpl has fewer complications. Second, if little or no blood is detected, the clinician performs a lavage of the peritoneal cavity with either normal saline or lactated. Diagnostic peritoneal lavage is sensitive for hemoperitoneum (99%), but not specific for liver injury. Open versus closed diagnostic peritoneal lavage in the evaluation of abdominal trauma.
Positive, lavage fluid red blood cells (lrbcs) greater than 100,000/mm3 or lavage fluid white blood cells (lwbcs) greater than 500/mm3;
Therefore, since the development of ultrasonography and advanced computed tomographic scanners, the role of dpl has been markedly reduced. Ultrasound (us) is highly sensitive in identifying >200 ml of intraperitoneal fluid. Indeterminate, lrbcs 50,000/mm3 to 100,000/mm3 or lwbcs 100 to 500/mm3; Rather than merely characterizing the color of the fluid as “salmon pink,” the inability to “read newsprint” through the fluid was used as a predictive criteria.
A negative test does not exclude other solid organ injury, viscus perforation, diaphragmatic tears, or retroperitoneal injury.
To analyze the effectiveness of peritoneal lavage and to define its limitations in the evaluation of patients who have sustained blunt abdominal trauma, a prospective study of 500 such patients was undertaken by the trauma service at the naval hospital, san diego. The procedure was initially used in patients with blunt abdominal trauma, but its use quickly evolved to include some patients with penetrating trauma [ 2,3 ].
