Background: Infants with congenital heart disease who require central venous lines are at increased risk of thrombosis. Heparin-bonded catheters provide protection from thrombotic events in some children. However, heparin-bonded catheters may not be as effective in infants
Study Design: This study was designed as a randomized, controlled, blinded single-center trial. Infants
Results: Eighty-seven patients were evaluable (41 of the patients were female). Thrombotic events occurred in 17 (42.5%) of 40 patients in the non-heparin-bonded catheter group and in 21 (44.7%) of 47 patients in the heparin-bonded catheters group. The study was stopped when the interim analysis showed convincing evidence for no difference between groups over the alternative hypothesis of 50% risk reduction.

Conclusions: Infants with congenital heart disease are at significant risk of both silent and clinically identified thrombosis. There seems to be no advantage in using heparin-bonded catheters in infants

Background: Safety culture development is essential for patient safety in healthcare institution. Perceptions of patient safety and cultural changes are reflected in patient safety reports; however, they were rarely investigated. The aim of this study was to investigate the perception of physicians and to explore the development of safety culture using quantitative content analysis for patient safety reports.

Background: People undergoing major orthopaedic surgery are at increased risk of postoperative thromboembolic events. Low molecular weight heparins (LMWHs) are recommended for thromboprophylaxis in this population. New oral anticoagulants, including direct factor Xa inhibitors, are recommended as alternatives.

One-lung ventilation is commonly used in lateral open chest surgery; however, it can increase pulmonary vascular resistance, which negatively affects Fontan circulation. Nevertheless, one-lung ventilation has a positive indication in post-Fontan patients. It allows surgery with lateral minimally invasive thoracotomy, which does not require a median sternotomy.

Background: In general, it is relatively easy to remove peripherally inserted central venous catheter (PICC) by gentle traction without any complications. However, the removal of PICC can be challenging occasionally. If the standard interventions fail to remove the catheter, there are no clear recommendations about what to do.
