Management of Hemoperitoneum

Initial Assessment and Stabilization

The management of hemoperitoneum requires rapid assessment of hemodynamic status, identification of bleeding source, and appropriate intervention based on patient stability, with immediate surgical control indicated for unstable patients despite resuscitation efforts 1, 2
Hemodynamic stability is the key factor in determining management strategy 3
For unstable patients, immediate resuscitation measures should include IV access, fluid resuscitation, and blood products if necessary 4
The time between injury and intervention should be minimized for patients requiring urgent bleeding control 4
Patients presenting with hemorrhagic shock and identified source of bleeding should undergo immediate surgical bleeding control unless initial resuscitation is successful 4

Extended Focused Assessment with Sonography for Trauma (E-FAST) should be performed to identify potential sources of bleeding 2, 4
E-FAST has 68-91% sensitivity and excellent specificity for detecting hemoperitoneum, with 100% sensitivity and specificity in hypotensive patients 5
Pelvic X-ray and chest X-ray should be obtained for patients who are hemodynamically unstable or require urgent intervention to stabilize vital signs 2, 4
When E-FAST and chest X-ray rule out extra-pelvic causes of hemorrhagic shock, angiography should be considered to visualize active arterial bleeding 2
The abundance of hemoperitoneum on E-FAST correlates with the need for laparotomy - 3 positive E-FAST sites (abundant hemoperitoneum) is associated with 61% appropriate laparotomies 1
A thoraco-abdomino-pelvic CT scan with intravenous contrast should be performed when hemodynamic status allows 2, 4
CT scan with contrast has high sensitivity (93.9%) and specificity (77.8%) for detecting active bleeding compared to angiography 1

Immediate resuscitation (IV access, fluids, blood products) is necessary for hemodynamically unstable patients 4
E-FAST, chest X-ray, and pelvic X-ray should be performed to identify bleeding source in hemodynamically unstable patients 1, 2
If extra-pelvic causes of hemorrhagic shock are ruled out, consider angiography/embolization for pelvic trauma with hemoperitoneum 1, 2
For abundant hemoperitoneum on E-FAST, consider emergency laparotomy 1
Thoraco-abdomino-pelvic CT scan with intravenous contrast should be performed for hemodynamically stable patients 2, 4

Diagnostic peritoneal lavage (DPL) has high sensitivity (>99%) for hemoperitoneum but is neither specific nor reliable for retroperitoneal injuries and is associated with 0.8-2.3% risk of complications 3
When pelvic trauma is associated with hemoperitoneum, the decision algorithm becomes more difficult and requires careful assessment of all potential bleeding sources 1

Don't rely solely on E-FAST to exclude all intra-abdominal injuries - it has lower sensitivity for bowel and mesenteric injuries 5
E-FAST performance may be diminished by false positives such as suffusion of a hemoretroperitoneum or intra-peritoneal bladder rupture 1
Don't delay intervention in unstable patients - the time between injury and intervention should be minimized 4

A large volume hemoperitoneum is defined as the presence of at least 500 ml of blood within the peritoneal cavity, which is the minimum amount typically detectable on emergency ultrasound imaging 6
Large volume hemoperitoneum refers to significant intraperitoneal blood accumulation (≥500 ml), which can be detected through various imaging modalities, particularly emergency ultrasound (EUS) 6, 7

The presence of large hemoperitoneum alone is considered a risk factor for non-operative management failure in splenic injuries, though it is not an absolute contraindication 8

Important pitfalls in diagnosing hemoperitoneum include blood clots forming rapidly in the peritoneum and having sonographic qualities similar to soft tissue, potentially being overlooked 6
Perinephric fat may be mistaken for hemoperitoneum 6
Fluid in the stomach or bowel may be mistaken for hemoperitoneum 6
Peritoneal free fluid is not identified by EUS until at least 500 ml is present, meaning a negative exam does not preclude early or slowly bleeding injuries 6
Non-traumatic fluid collections such as ascites may be mistakenly attributed to trauma 6
