Abstract
A randomized prospective study compared open peritoneal lavage using a peritoneal dialysis catheter with modified closed lavage using either the Lazarus-Nelson or Cook lavage catheter. The time required to perform the lavage, technical difficulties, complications, and accuracy were assessed in 63 adult victims of blunt abdominal trauma. The average time to perform lavage was 21.1 minutes for open lavage, 14.7 minutes for Lazarus-Nelson closed lavage, and 9.8 minutes for Cook closed lavage. The closed technique using the Cook catheter was significantly faster than open lavage. Technical difficulties were significantly less frequent with Cook catheter closed lavage than with Lazarus-Nelson catheter closed lavage. The overall complication rate was 1.8%, and the overall accuracy was 98.1%, without apparent difference among techniques. It is concluded that, when no contraindications to closed lavage exist, and when time is of importance, closed lavage with the Cook catheter is the preferred technique.
