Central Venous Catheter Use in Burn Patients: Complications and Preventive Measures

Summary: The use of a central venous catheter (CVC) is essential in the management of burn patients, especially due to the difficulty of venous access, the length of hospitalization, and the need for routine fluid replenishment and medication administration, particularly antibiotics. Aim of the study: The aim of this study is to identify the rate of complications associated with central venous catheters in the context of burn patients to discuss its indications and the benefit/risk ratio. Methods: This descriptive retrospective study was conducted in the Plastic Surgery Department of CHU Mohamed VI in Marrakech, involving patients who received a central venous catheter during their admission to the burn unit from March 2023 to March 2024. Data collection included basic demographic data, comorbidities, burn mechanism, burn depth, percentage of burned body surface area (BSA), central catheter location (subclavian, femoral, jugular), the site (healthy/burned), the duration of catheter placement, complications (infection and venous thrombosis), detection of germs during culture, and the length of hospital stay. Results: Infection and venous thrombosis were identified as the most frequent complications of CVC use. Further research is needed to evaluate the role of regular CVC changes (every 10 to 15 days after insertion) in preventing infections and to establish a clear anticoagulation protocol for preventing deep vein thrombosis (DVT). Conclusion: While CVCs can be a valuable resource in the treatment of burn patients, they are associated with significant risks, some of which may be life-threatening. The duration of CVC placement should be minimized, and blood cultures (preferably from the CVC tip) should be systematically sent after 10 days or at the first suspicion of complications to reduce the incidence and severity of CVC-related infections.
