Summary

Primary elective open sternum with delayed closure effectively manages neonatal mediastinal compression post-cardiac surgery. This approach showed similar mortality to primary sternal closure, despite treating sicker infants.

Area of Science:

  • Cardiovascular Surgery
  • Neonatal Medicine
  • Thoracic Surgery

Background:

  • Neonatal cardiac surgery often necessitates sternal closure.
  • Complications such as mediastinal compression can arise.
  • Surgical techniques aim to optimize outcomes in critically ill neonates.

Purpose of the Study:

  • To compare primary elective open sternum with delayed sternal closure versus primary sternal closure in neonates undergoing cardiac operations.
  • To evaluate the efficacy and safety of these two sternal closure methods.

Main Methods:

  • Retrospective analysis of 89 neonates undergoing cardiac operations.
  • Comparison between primary elective open sternum/delayed sternal closure and primary sternal closure groups.
  • Selective use of open sternum based on intraoperative hemodynamic or respiratory status.

Main Results:

  • No significant difference in overall mortality between the two groups (20% vs. 14.7%).
  • Shorter mechanical ventilation and hospital stay durations in the primary sternal closure group (p=0.0005 and p=0.004, respectively).
  • 20.6% of primary sternal closure patients required delayed sternal reopening for low cardiac output, compared to one superficial wound infection in the delayed closure group.

Conclusions:

  • Primary elective open sternum with delayed sternal closure is an effective strategy for managing neonatal mediastinal compression post-cardiac surgery.
  • This approach demonstrates low morbidity and comparable mortality to primary sternal closure, even in critically ill neonates.
  • Delayed sternal closure avoids the need for reoperation in a significant proportion of neonates who might otherwise require it for low cardiac output.
