Abstract
Tunnelled catheters improve venous access in haematological diseases and malignancies, but are associated with complications. We prospectively analysed the episodes of CABSI and its associated risk factors. To study the incidence and risk factors for CABSI in children with tunnelled central venous catheters (both Hickmans and Chemoports). This is a prospective observational study done at our institute. Children under the age of 18 who underwent insertion of a Hickman or Chemoport from March 2018 to Dec 2022 were enrolled. Episodes of CABSI were noted and its risk factors were analysed. In total, 258 catheters were inserted in 250 children. Age ranged from 1 month to 18 years (median 67 months) with 60% being boys. A total of 152 Hickmans, 106 chemoports were inserted. Indications for insertions were for requirement of BMT and chemotherapy in majority of cases. CABSI were seen in 28.6% of catheters. Younger children (< 4years), Neutropenia (counts < 1000) and use of TPN were significantly associated with CABSI(p value<0.05). Infection was more with externalized catheters (Hickman) than implantable ports (Chemoports) but was not statistical significant(p value>0.05). Almost 30% of catheters with CABSI required removal because of florid sepsis. Others could be salvaged with aggressive antibiotics. CABSI is a serious complications related to tunnelled catheter. Smaller children (<4 years), neutropenia and usage of TPN is a risk factor for development of CABSI. It can be treated with appropriate antibiotics and required removal in almost a third of all the cases.
