Delayed sternal closure is not a significant risk factor for mediastinitis in pediatric cardiac surgery patients. Effective treatment involves debridement and primary closure, leading to excellent outcomes.

Area of Science:

  • Pediatric Cardiac Surgery
  • Infectious Disease Management
  • Thoracic Surgery

Background:

  • Mediastinitis poses significant morbidity in pediatric cardiac surgery patients.
  • The role of delayed sternal closure as a risk factor for mediastinitis is unclear.
  • Current management strategies for mediastinitis are debated.

Purpose of the Study:

  • To investigate the association between delayed sternal closure and mediastinitis in pediatric cardiac surgery.
  • To evaluate the outcomes of mediastinitis management in this patient population.

Main Methods:

  • Retrospective review of pediatric mediastinitis cases from 1991 to 2004.
  • Analysis of infection incidence, timing, and risk factors, including sternal closure method.
  • Evaluation of clinical signs and treatment outcomes.

Main Results:

  • The incidence of mediastinitis was 1.1% (29 cases in 2,675 procedures).
  • Delayed sternal closure showed an odds ratio of 1.88 (not statistically significant) for infection.
  • Common signs included fever, erythema, purulent drainage, and wound dehiscence.

Conclusions:

  • Delayed sternal closure is not a major risk factor for pediatric cardiac surgery-associated mediastinitis.
  • Debridement and primary closure yield excellent results for treating mediastinitis.
  • Primary skin closure with delayed sternal closure may mitigate risks.
