Objective: Central venous catheters are mainly used for safe fluid infusion, total parenteral nutrition, and evaluation of hemodynamic parameters. Complications related to central venous access can occur during insertion, after insertion or during catheter maintenance. The aim of this study was to investigate the demographic data and the presence of catheter-related complications in pediatric patients with central venous catheters in our hospital. Methods: This study retrospectively reviewed demographic data and the presence of catheter-related complications in pediatric patients with central venous catheters in our hospital from June 1, 2019, to February 28, 2023. Results: Patients who underwent central venous catheterisation in our hospital between June 2020 and February 2023 were included in the study. When the demographic data of the patients were evaluated, 141 (57.8%) of our patients were male and 103 (42.2%) were female, and there was no statistically significant difference between the groups. In the femoral group, catheterisation of the right femoral vein was preferred more than the left vein (72.2%-27.7%), whereas in the jugular-subclavian group, the right internal jugular vein was preferred more than other sites. The risk of infection was statistically higher in the femoral group compared to the subclavian group. Conclusion: In clinical practice, we think that the risk of complications can be reduced in central venous catheter applications in pediatric patients by experienced personnel by complying with asepsis/antisepsis conditions and using appropriate imaging devices.

Background/aims Sepsis is one of the major problems encountered in intensive care units, causing organ damage and increasing mortality. Suberosin (SBR) is a type of coumarin with antioxidant and anti-inflammatory activities. The goal of this study is to explore the protective effects of SBR on the lungs in a rat model of sepsis. Methods Male Wistar rats were utilized in this study. A cecal ligation and puncture (CLP) model was applied to induce sepsis. Rats were separated into six groups with nine animals in each group, including healthy control, SBR, CLP, and CLP + SBR (5, 10, and 20 mg/kg) groups. Superoxide dismutase (SOD), glutathione (GSH) enzyme activities, and malondialdehyde (MDA) level were measured via enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expressions of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) were evaluated by real-time polymerase chain reaction (RT-PCR). Histopathological changes in the lungs were investigated with hematoxylin and eosin (H&E). Results MDA levels and GSH and SOD enzyme activities were negatively affected in the CLP group, but SBR treatment ameliorated these oxidative stress parameters in the SBR1-3 groups (p

Background/Aims Sepsis is an uncontrolled systemic infection, withcomplex pathophysiology that may result in acute lung organ damage and cause multiple organ failure. Although much research has been conducted to illuminate sepsis’s complex pathophysiology, sepsis treatment protocols are limited, and sepsis remains an important cause of mortality andmorbidity in intensive care units.Various studies have shown that idebenone (IDE) possesses strong antioxidant properties, which inhibit lipid peroxidation and protect cells from oxidative damage. The present study aimed to evaluate the protective effects of IDE against lung injury in a cecal ligation and puncture (CLP)-induced sepsis rat model. Methods Male albino Wistar rats were used. The animals were divided into a healthy control (no treatment), CLP, IDE control (200 mg/kg), and CLP + IDE subgroups (50 mg/kg, 100 mg/kg, and 200 mg/kg), with nine rats in each group.IDE was administered 1 h after CLP induction.To evaluate the protective effects of IDE, lung tissues were collected 16 h after sepsis for biochemical, immunohistochemical staining, and histopathological examination. Results IDE significantly ameliorated sepsis-induced disturbances in oxidative stress-related factors, with its effects increasing in accordance with the dose.IDE also abolished histopathological changes in lung tissues associated with CLP.Furthermore, interleukin 1 beta (IL-1β)and tumor necrosis factor-alpha (TNF-α) immunopositivity markedly decreased in the septic rats following IDE treatment. Conclusions IDE largely mitigated the inflammatory response in sepsis-induced lung injury by decreasing free radicals and preventing lipid peroxidation. The results suggest that IDE may represent a potential novel therapeutic drug for sepsis treatment.
