尿道留置カテーテルに伴うセラチア感染とその対策

Abstract

Thirty-four out of 171 in-patients, requiring indwelling urethral catheter after admission, acquired urinary tract infection with Serratia marscens inspite of adopting close drainage system. Most patients had underwent some urological surgery before urinary infection, and moreover almost all of the patients had received some antibiotics such as carbenicillin, sulbenicillin or cephalothin in prevention of post-operative infection. It was found that Serratia infection was primarily caused by undue management of inlying urethral catheter and erroneous drainage of urine from the drainage bag. We could eradicated almost completely urinary infection with S. marscens by controlling closed drainage system with more caution and strictness.
