Blunt hepatic injury and elevated hepatic enzymes: a clinical correlation in children
Insights
Elevated liver enzymes (SGOT, SGPT) in children with blunt abdominal trauma indicate a high risk for significant liver injury. Prompt testing can identify at-risk pediatric patients needing further imaging.
Area of Science:
- Pediatric Traumatology
- Hepatology
- Diagnostic Imaging
Background:
- Blunt abdominal trauma in children poses diagnostic challenges.
- Noninvasive imaging is crucial for evaluating pediatric abdominal injuries.
- Early identification of liver injury is critical for timely management.
Purpose of the Study:
- To identify early biochemical markers for liver injury in pediatric blunt abdominal trauma.
- To define a high-risk group of children requiring further noninvasive imaging.
- To improve the diagnostic accuracy for liver injuries in pediatric trauma patients.
Main Methods:
- Prospective, nonrandomized comparison of noninvasive imaging techniques.
- Analysis of serum hepatic enzyme levels (SGOT, SGPT) in 100 children.
- Correlation of enzyme levels with diagnosed liver injuries in hemodynamically stable patients.
Main Results:
- 44% of stable children showed immediate hepatic enzyme elevation (SGOT, SGPT > 30 IU).
- 19 children (43% of those with elevated enzymes) had significant liver injuries.
- Children with liver injuries had significantly higher enzyme levels than those without (P < 0.0001).
- No child with liver injury had normal enzyme levels on admission.
Conclusions:
- Elevated SGOT and SGPT levels are reliable early indicators of significant liver injury in children with blunt abdominal trauma.
- This biochemical marker helps define a high-risk pediatric population for further imaging.
- Emergent hepatic enzyme testing is recommended for all children with suspected upper abdominal trauma.
Abstract:
During a recent prospective nonrandomized comparison of noninvasive imaging techniques in 100 children with suspected major blunt abdominal injury, an interesting subset of patients was defined. Of 95 hemodynamically stable patients, 44 were found to have immediate elevation of hepatic enzymes (SGOT, SGPT greater than 30 IU). Nineteen of these children (43%) were subsequently shown to have significant liver injuries. No child with a liver injury had normal enzymes on admission. The level of enzyme elevation (SGOT chi 890 +/- 142 IU, SGPT chi 536 +/- 105 IU) in those with liver injuries is significantly greater than those without injury (SGOT chi 273 +/- 44 IU, SGPT chi 115 +/- 19 IU) (P less than or equal to 0.0001 SGOT. P less than or equal to 0.0001 SGPT). Our study has allowed definition of a group of children who are at significant risk for liver injury based on immediately available serum determinations of GOT and GPT. We have begun to use this information in our institution to select children for further noninvasive imaging. We recommend that these studies be obtained emergently in all children with suspected upper abdominal trauma.
