Abstract
Background: Paediatric cancer and critically ill patients frequently require central venous catheters for prolonged intravenous therapy. The aim of this study is to compare the difficulty of catheter insertion and the morbidity related to this procedure in these two populations and to investigate risk factors for complications Methods: This prospective observational study was conducted at the Hedi Chaker University Hospital in Sfax, Tunisia, from July 2021 to July 2022. We included all patients aged three months to 14 years who required an infraclavicular subclavian vein catheterization. Patients were divided into two groups: Group 1 included children with malignancies; and Group 2 included critically ill paediatric patients. Then, we compared the demographic data, the difficulty of the catheterization procedure, and catheter-related complications. We also investigated risk factors for complications using a logistic regression model. The significance level was P<0.05 Results: We included 65 infants and children requiring central venous access, 28 of whom suffered from malignancies. The demographic parameters were comparable. However, the time for the procedure and the number of attempts were higher in the malignancy group with P<0.001. Central venous catheter complications were present 46.4% of the time in Group 1 compared to 21.6% in Group 2 (P=0.032). Malignancies were associated with an increased risk of complications (aOR = 2.95; 95%CI: 0.63-13.8) Conclusions: This study showed increased difficulty and higher morbidity related to infraclavicular subclavian vein catheterization among infants and children suffering from cancer
