Summary
Somatosensory-evoked potential (SSEP) changes occurred in 40% of aortic coarctation repairs, often prompting interventions like blood pressure adjustments. Importantly, no neurologic deficits were observed in these patients.
Area of Science:
- Neurophysiology
- Pediatric Cardiac Surgery
- Intraoperative Monitoring
Background:
- Aortic coarctation repair is a complex procedure.
- Intraoperative monitoring is crucial for patient safety.
- Somatosensory-evoked potentials (SSEPs) can detect neural compromise.
Purpose of the Study:
- To determine the incidence of SSEP changes during aortic coarctation repair.
- To identify interventions based on SSEP changes.
- To assess the neurological outcomes associated with SSEP monitoring.
Main Methods:
- Retrospective review of 84 children undergoing aortic coarctation repair (1984-1996).
- Continuous SSEP monitoring throughout surgical procedures.
- Definition of significant SSEP change: >50% amplitude decrease from baseline.
Main Results:
- SSEP changes occurred in 40% of 87 procedures.
- Interventions based on SSEP changes (e.g., clamp repositioning, BP elevation) were performed in 26.4% of procedures.
- No patient experienced a neurologic deficit.
Conclusions:
- SSEP monitoring is valuable during aortic coarctation repair.
- SSEP changes are frequently observed and often reversible with timely interventions.
- This study represents a significant series on SSEP use in this surgical context.
