Implementing a standardized perioperative antibiotic prophylaxis protocol for neonates undergoing cardiac surgery

Area of Science:

• Pediatric Cardiac Surgery
• Infectious Disease Prevention
• Clinical Protocol Development

Background:

• Lack of standardized perioperative antibiotic prophylaxis guidelines for neonatal cardiac surgery leads to practice variability.
• Surgical site infections (SSIs) are a concern in neonatal cardiac procedures.
• Existing practices lacked clear evidence-based recommendations.

Purpose of the Study:

• To determine the safety of a new perioperative antibiotic prophylaxis protocol for neonatal cardiac surgery by assessing SSI rates.
• To evaluate compliance with key process measures of the implemented protocol.
• To establish a foundation for evidence-based national guidelines.

Main Methods:

• Quasi-experimental study design involving neonates undergoing cardiac procedures (July 2009-June 2012).
• Development and implementation of a standardized perioperative antibiotic prophylaxis protocol.
• Comparison of SSI rates and compliance metrics between pre- and post-intervention periods.

Main Results:

• No significant difference in SSI rates between pre-intervention (6.21/100) and post-intervention (5.80/100) periods.
• Significant improvement in compliance with antibiotic drug selection, dosage, timing, and duration.
• The protocol demonstrated safety and improved adherence to best practices.

Conclusions:

• Restricting antibiotic prophylaxis duration (24-48 hours) is safe for neonatal cardiac surgery with closed sternums.
• The standardized protocol improved compliance without increasing SSI rates.
• Further multicenter studies are recommended to develop national guidelines for this patient population.
