Hemodiafiltration combined with polymyxin B-immobilized fiber column direct hemoperfusion is effective for acute postoperative exacerbation of interstitial pneumonia: a case report.

BACKGROUND: Postoperative acute exacerbation of interstitial pneumonia has a high mortality rate; however, its treatment methods have not been standardized. CASE PRESENTATION: A 72-year-old man with rheumatoid arthritis developed acute respiratory failure about 3 weeks after lung cancer surgery. There were increased diffuse frosted shadows in both lung fields. His condition was diagnosed as an acute exacerbation of interstitial pneumonia associated with rheumatoid arthritis, and he was started on steroid pulse therapy; however, his respiratory condition deteriorated. He was urgently intubated and started on veno-venous extracorporeal membrane oxygenation. Further, intensive care, including blood purification therapy, was initiated. The blood purification therapy comprised a combination of hemodiafiltration and 6-h polymyxin B-immobilized fiber column direct hemoperfusion. The patient was weaned off veno-venous extracorporeal membrane oxygenation, extubated, and discharged from the intensive care unit on the ninth day. CONCLUSIONS: Blood purification therapy was effective for acute exacerbation of interstitial pneumonia.

Current status of antimicrobial prophylaxis during extracorporeal membrane oxygenation in Japan: a national survey.

Infection during extracorporeal membrane oxygenation (ECMO) is a common complication that leads to increased mortality. Thus, antimicrobial prophylaxis during ECMO is often performed to prevent of nosocomial infections. However, the current status of antimicrobial prophylaxis during ECMO in Japan is unclear. Therefore, we conducted a national survey of members of the Japanese Society of Intensive Care Medicine (JSICM) to clarify the current status of antimicrobial prophylaxis during ECMO in intensive care units. An 11-question survey was devised to assess antimicrobial prophylaxis and surveillance practices during ECMO. A total of 253 hospitals responded. Of these, 235 hospitals were the JSICM-certified hospitals, and the response rate was 64%. A total of 96 hospitals (39%) administered antimicrobial prophylaxis during ECMO, and 17% of hospitals had a standardized protocol for antimicrobial prophylaxis during ECMO. Of these 96 hospitals, 79% used single agents. First-generation cephalosporins were the most commonly used (54%), followed by penicillins or penicillin-derived combinations (24%), second-generation cephalosporins (7%), and anti-methicillin-resistant Staphylococcus aureus agents (6%). In conclusion, our survey revealed 39% of hospitals administered antimicrobial prophylaxis during ECMO in Japan. First-generation cephalosporins were the agents most commonly used.
