Liver Laceration Precautions
For hemodynamically stable patients with liver laceration, serial clinical evaluations with physical exams and laboratory testing must be performed continuously during non-operative management, with CT imaging serving as the gold standard for initial assessment and ongoing monitoring. 1
Initial Assessment and Monitoring Requirements
Hemodynamic Status Determines Management Pathway
Hemodynamically stable patients should undergo CT scan with intravenous contrast as the gold standard diagnostic tool, which is mandatory before considering non-operative management (NOM). 1
E-FAST ultrasound provides rapid detection of intra-abdominal free fluid and should be performed immediately on arrival. 1
Serial clinical evaluations including physical examinations and laboratory testing (particularly hemoglobin levels) must be performed continuously to detect any change in clinical status during NOM. 1
ICU Admission Criteria
Moderate injuries (WSES II/AAST III) and severe injuries (WSES III/AAST IV-V) require ICU admission for continuous monitoring. 1
Minor injuries (WSES I/AAST I-II) may not require ICU-level care if truly isolated and hemodynamically stable. 1
Continuous monitoring in an ICU or ER setting with immediate availability of trained surgeons, operating room, angiography capabilities, and blood products is essential for moderate to severe injuries. 1
Critical Monitoring Parameters
Watch for Clinical Deterioration
Decreasing hemoglobin levels are a key indicator of ongoing bleeding—a drop from 14.6 g/dL to 8.4 g/dL over 3 hours signals need for intervention. 2
Hypotension (mean arterial pressure <65 mmHg) or **tachycardia** (heart rate >120) indicate hemodynamic instability requiring immediate surgical or angiographic intervention. 2, 3
Development of peritonitis on serial abdominal examinations mandates surgical exploration. 2
Angiography Readiness
Arterial blush on CT scan in hemodynamically stable patients should prompt consideration for angiography/angioembolization (AG/AE) as first-line intervention. 1
Immediate access to angiography and angioembolization capabilities must be available, as this is essential for managing persistent arterial bleeding. 1, 4
Activity and Mobilization Precautions
Early Mobilization Protocol
Early mobilization should be achieved in stable patients to reduce complications including venous thromboembolism. 1
This recommendation applies only after hemodynamic stability is confirmed and there is no evidence of ongoing bleeding. 1
Thromboprophylaxis Timing
Mechanical prophylaxis (intermittent pneumatic compression devices) is safe and should be started immediately in all patients without absolute contraindication. 1
LMWH-based prophylaxis should be started as soon as possible following trauma and is safe in selected patients with liver injury treated with NOM. 1
The key is balancing bleeding risk against thromboembolism risk—mechanical prophylaxis carries minimal bleeding risk and should be universal. 1
Nutritional Support
Early Enteral Feeding
Enteral feeding should be started as soon as possible in the absence of contraindications such as bowel injury or hemodynamic instability. 1
Early nutrition reduces complications and supports healing in stable patients. 1
Anticoagulation Management
Reversal Considerations
Individualization of risk-benefit balance for anticoagulant reversal is required in patients taking anticoagulants at time of injury. 1
This is a Grade 1C recommendation, meaning clinical judgment is paramount based on injury severity and bleeding risk. 1
Delayed Complications Surveillance
Biliary Complications
Symptomatic or infected bilomas require percutaneous drainage as first-line management. 1
Bile leaks may develop days after initial injury—a case report documented bile leak requiring ERCP and stenting one week post-discharge. 5
Serial imaging may be needed if clinical signs suggest biloma formation (fever, abdominal pain, leukocytosis). 5
Delayed Hemorrhage
Delayed hemorrhage without severe hemodynamic compromise should be managed first with AG/AE rather than immediate surgery. 1
Hepatic artery pseudoaneurysm should be managed with AG/AE to prevent rupture, which can be catastrophic. 1
Abscess Formation
- Intrahepatic abscesses may develop as a delayed complication and should be treated with percutaneous drainage. 1
Common Pitfalls to Avoid
Failure to Recognize Deterioration
The most critical error is failing to recognize hemodynamic deterioration during attempted NOM—this requires continuous monitoring, not intermittent checks. 3
A trauma team approach reduces time to hemostatic intervention by a median of 94 minutes for embolization and 50 minutes for surgery, with 65% reduction in 72-hour mortality. 3
Premature Discharge
Patients require adequate observation period before discharge, as complications like bile leak can manifest days later. 5
Interval laparoscopic exploration may be considered if intra-abdominal injury is suspected in days after initial trauma. 1
