Central Venous Catheter-Related Infection in Critically Ill Patients
Journal Title: Sultan Qaboos University Medical Journal - Year 2019, Vol 19, Issue 3
Abstract
We read with great interest recent studies about infections related to central venous catheter (CVC) and associated risk factors in critically ill postoperative patients evaluated in Iran, Oman and Egypt.1–4 Beigmohammadi evaluated 66 Iranian patients who were in the intensive care unit (ICU) following cancer surgery.1 He reported 23 simple CVCs without antimicrobials and 43 CVCs impregnated with antimicrobial agents—with 28 impregnated internally and 15 impregnated internally and externally.1 Te jugular (51.5%) and subclavian (48.5%) veins were the sites for insertion of the catheters. CVC-related infection was confrmed by positive cultures of blood samples from the catheters. A total of 22.7% of cases had positive blood cultures and 9.1% had catheter-related bloodstream infections; therefore, there were 5.8 infections per 1,000 catheter-days for CVCs.1 Tere were no signifcant differences between simple and impregnated CVCs with respect to catheter tip colonisation, as well as in relation to the prevention of bloodstream infections.1 Hamid et al. evaluated the early and late complications of 204 doublelumen cuffed tunnelled CVCs placed in 161 patients in a tertiary healthcare centre in Oman.2 Te jugular (90.6%) and femoral (9.4%) veins were the sites for insertion of the catheters and infections were detected in 29 catheters (22%) in 22 patients. Staphylococcus aureus (55.2%), acinetobacter and pseudomonas (20.6% each) were the main infectious agents. A total of 18 (62.1%) cases had a haematogenous origin, four (13.8%) were exit site infections, and seven (24.1%) were both. Most infected catheters had to be removed and few infections improved with antibiotics.2 Khalil and Azqul’s prospective study in Egypt included 111 cardiac patients with CVCs. Tey found 11 (9.9%) cases of infection by the following agents: coagulase negative staphylococci, acinetobacter, Alcaligenes faecalis, enterobacter and klebsiella. Te compliance of health workers to CVC care recommendations played a role in the presence of infections.
