Guidelines from the Centers for Disease Control and Prevention (CDC) 16 and a randomised clinical trial 25 indicated that when comparing multi-lumen central catheters (CVCs) with single-lumen central catheters, the former showed a higher incidence of infections. Thrombosis rates were statistically higher in the larger diameter catheters (p = 0.001). Grove and Pevec 24 reviewed the records of 678 patients with PICCs. Other researchers determined that a larger external diameter of the catheter increases the risk of venous thrombosis. Other statistically significant risk factors were noted, however the authors concluded that the number of lumens was not a factor in the development of thrombosis. Yi et al 23examined predictive risk factors for thrombus formation in patients with PICCs using ultrasound. Zochios et al 22 concluded that larger, multi-lumen PICCs demonstrated a higher incidence of thrombosis due to turbulence and restricted blood flow. The number of lumens and the size of the catheter have been described as risk factors for thrombus formation 21. Anticoagulation can be initiated, preventing further complications. Not all occlusions lead to upper extremity venous thrombosis (UEVT), and thrombotic occlusions can be treated with antithrombotic agents, while UEVT is treated symptomatically or with catheter removal. The literature describes occlusion rates in PICCs and links them to the number of lumens selected, reporting occlusion rates ranging from 7% to 34%, with fibrin sheath formation being a common cause of mechanical occlusion 20. Depending on the clinical situation, preference should be given to single-lumen devices as outlined in clinical practice guidelines 16-19. These findings have prompted a greater focus on ensuring appropriate use of the PICC in hospitalised patients, including recommendations on the “appropriate choice of vascular access type 16-17“.ĭouble and triple-lumen PICCs (Figure 2) are associated with an increase in occlusion. Ī recent study, for example, found considerable variation in the use of the PICC, indications for use and associated complications in a sample of 10 hospitals 15. The catheter can be changed using the existing puncture.However, the choice of device may in some cases be due to the limited information defining the appropriate indications for use of the single-lumen (Figure 1) versus the multi-lumen PICC 14. The intra-catheters are intended for percutaneous introduction using the It allowsĪlso the catheter to remain for extended periods in the body. The catheters are semirigidĪt room temperature and get softer when reaching body temperature thus minimizing the possibility of vessel wall injuries. It is extremely smooth and has a non-thrombogenic surface. The radiopaque, thermosensitive and anti-kinking PUR-material with aīlue soft-tip guarantees a high biocompatibility. Three-lumen catheters for subclavian-jugular-femoral application. The dialysis machine to form a complete circuit for the removal and return of the patient‘s blood during treatment. The multiple lumen catheters contain two large bore lumen that are connected to Until another type of dialysis therapy is substituted. Hemodialysis catheters are catheters that provide temporary vascular access for hemodialysis until a permanent access is available or
