Insights
Pediatric patients on extracorporeal life support (ECLS) with retained hemothorax can be safely treated with intrapleural fibrinolysis. This nonsurgical approach avoids the risks of surgery during ECLS, offering a viable alternative for managing hemothorax.
Area of Science:
- Pediatric critical care medicine
- Cardiovascular surgery
- Pulmonary medicine
Background:
- Pediatric patients requiring extracorporeal life support (ECLS) for cardiorespiratory failure face high risks of intrapleural hemorrhage.
- Retained hemothorax in these patients necessitates intervention to prevent complications like empyema and fibrothorax.
- Surgical evacuation, the standard treatment, is hazardous during ECLS due to bleeding risks.
Observation:
- This study reports on two pediatric cases of retained hemothorax during ECLS.
- Both patients were treated with intrapleural fibrinolysis using tissue plasminogen activator.
- The treatment aimed to facilitate nonsurgical evacuation of the hemothorax.
Findings:
- Intrapleural fibrinolysis was successfully and safely administered to both pediatric patients.
- The nonsurgical approach effectively managed the retained hemothorax during ECLS.
- This method provided an alternative to hazardous surgical interventions.
Implications:
- Intrapleural fibrinolysis represents a safe and effective nonsurgical option for pediatric patients with retained hemothorax on ECLS.
- This approach may reduce the risks associated with surgical interventions in critically ill pediatric patients.
- Further research could explore the broader application of intrapleural fibrinolysis in similar pediatric critical care scenarios.
Abstract:
Pediatric patients who require extracorporeal life support (ECLS) for refractory cardiorespiratory failure are at increased risk for intrapleural hemorrhage due to the effects of systemic anticoagulation and frequent occurrence of pneumothorax. Surgical evacuation is standard therapy for retained hemothorax to prevent secondary empyema, pulmonary compression, and development of fibrothorax. However, surgical interventions during ECLS are hazardous and place patients at increased risk for surgical site bleeding. Intrapleural fibrinolysis with tissue plasminogen activator may be used to facilitate nonsurgical evacuation of retained hemothorax. We present two pediatric patients who were safely and successfully managed with intrapleural fibrinolysis of retained hemothorax during ECLS.
