Abstract Objective: To analyze the pathogenic bacteria distribution and risk factors of postoperative pulmonary infection in children with abdominal surgery. Methods: The clinical data of 835 cases of children with abdominal surgery in our hospital from April 2013 to April 2017 were retrospectively analyzed. The pathogenic bacteria in 91 cases of children with pulmonary infection were identified, and the pathogenic bacteria distribution was recorded, and the risk factors for children with postoperative pulmonary infection were analyzed. Results: Among 91 cases of children with postoperative pulmonary infection, there were 47 cases (51.65%) with mixed infection and 44 cases (48.35%) with pure infection, and 230 specimens were obtained and 88 pathogenic bacteria strains were detected. There were 49 strains (55.68%) of gram-negative bacteria, 31 strains (35.23%) of gram-positive bacteria and 8 strains (9.09%) of fungi, and the acinetobacterhaemolyticus, klebsiellapneumoniae, staphylococcus haemolyticus and staphylococcus aureus were the main pathogenic bacteriaan. They accounted for 18.18%, 14.77%, 14.77% and 11.36% respectively. Surgical methods, surgical site, congenital heart disease, albumin level before surgery, whether to use antibiotics before surgery, postoperative mechanical ventilation time, invasive operation, chronic respiratory diseases were the risk single factors affecting the postoperative pulmonary infection in children with abdominal surgery (P<0.05). The albumin before surgery,postoperative mechanical ventilation time, invasive operation and chronic respiratory diseases were independent risk factors for postoperative pulmonary infection in children with abdominal surgery (P<0.05). Conclusion: Gram-negative bacteria are the main pathogenic bacteria of postoperative pulmonary infection in children with abdominal surgery, and the pulmonary infection is related to the preoperative albumin level before surgery, postoperative mechanical ventilation time, invasive operative, chronic respiratory diseases and other factors, and the clinical application should take effective preventive measures against various risk factors.
