[Children's serum hepatitis after open heart surgery: follow-up of 230 patients]

Area of Science:

• Cardiology
• Hepatology
• Pediatric Surgery

Background:

• Congenital heart diseases necessitate surgical intervention in pediatric populations.
• Open-heart surgery involves significant blood transfusions and potential exposure to blood-borne pathogens.
• Serum hepatitis (Hepatitis B) is a concern in healthcare settings with blood product usage.

Purpose of the Study:

• To investigate the incidence of serum hepatitis in children following open-heart surgery.
• To determine if blood transfusion volume correlates with serum hepatitis development after pediatric cardiac surgery.

Main Methods:

• A retrospective study of 230 children undergoing open-heart surgery between 1984 and 1989.
• Follow-up assessments to identify cases of post-operative serum hepatitis.
• Statistical analysis comparing the incidence in the surgical group versus the general population and examining the effect of transfusion volume.

Main Results:

• Eleven out of 230 children (4.78%) developed serum hepatitis post-surgery.
• The incidence of serum hepatitis in the surgical group was significantly higher than the natural incidence (0.039%, P < 0.001).
• Statistical analysis indicated no significant correlation between the volume of blood transfused and the incidence of serum hepatitis (P > 0.50).

Conclusions:

• Open-heart surgery in children with congenital heart disease is associated with a substantially increased risk of developing serum hepatitis.
• Blood transfusion volume does not appear to be a determining factor for serum hepatitis incidence in this context.
• Implementing specific preventive measures is crucial to mitigate the risk of serum hepatitis in pediatric patients undergoing cardiac surgery.
