Management of high-grade splenic injury in children

Area of Science:

• Pediatric Surgery
• Trauma Surgery
• Pediatric Critical Care

Background:

• High-grade blunt splenic injuries in children present significant management challenges.
• Splenic trauma management strategies include early operation and initial nonoperative management.
• Outcomes and predictors of failure in pediatric splenic trauma require further investigation.

Purpose of the Study:

• To evaluate the outcomes of operative versus nonoperative management for high-grade blunt splenic injuries in children.
• To identify factors associated with the need for surgery and failure of nonoperative management.
• To compare mortality and hospital resource utilization between different management strategies.

Main Methods:

• Retrospective analysis of the National Trauma Databank (2001-2005).
• Inclusion criteria: children (<= 14 years) with high-grade blunt splenic injury (AIS > or = 4).
• Comparison of early operation (within 6 hours) versus initial nonoperative management (NOM).

Main Results:

• Overall mortality was 13.5%.
• Initial nonoperative management (NOM) was successful in 84% of patients.
• Operative intervention was necessary in 42% of cases, with 74% of these undergoing early operation (EOM).
• Early operation and failure of NOM were associated with lower blood pressure, lower Glasgow Coma Scale scores, higher Injury Severity Score, longer hospital stay, and higher mortality.
• Failure of NOM had similar mortality and length of stay compared to EOM.

Conclusions:

• Nearly half of pediatric patients with high-grade splenic injury require operative treatment.
• Nonoperative management is usually successful with careful patient selection and close monitoring.
• Delayed operation is required in 16% of cases initially managed nonoperatively, emphasizing the importance of vigilant observation.
