Abstract

Background: Surgical site infection (SSI) is a major complication of pediatric cardiac surgery. If the risk of developing SSI can be predicted based on the patient’s preoperative background, appropriate preoperative management to prevent the development of SSI can be achieved. Methods: We retrospectively studied cases for patients younger than 7 years of age among surgeries performed through a median sternotomy at Kagoshima University Hospital from April 2011 to March 2021. SSI was diagnosed according to the Centers for Disease Control and Prevention guidelines and classified into 3 types: superficial incisional SSI (SiSSI), deep incisional SSI (DiSSI) and mediastinitis. Results: Of the 765 consecutive pediatric cardiac surgeries, 597 were included in the analysis based on the exclusion criteria. Of these, 17 (2.8%) developed SSI (3 SiSSI cases, 2 DiSSI cases and 12 mediastinitis cases), with Staphylococcus aureus as the major pathogen. Univariate analysis revealed that low preoperative serum protein (P = 0.049) and low serum albumin levels (P = 0.023) were risk factors for the development of SSI. No findings suggested impaired hepatic synthesis, inflammatory disease or protein loss from the kidney or intestinal tract. We concluded that malnutrition caused low serum protein and albumin levels. Conclusions: Low preoperative serum protein and albumin levels are risk factors for SSI development of SSI. Nutritional status should be regularly assessed in children scheduled for cardiac surgery, and interventions, such as nutritional guidance, should be considered if malnutrition is suspected.
