Catheter dysfunction is an important cause of catheter loss. In order to prevent this, locking solutions with minimal risk of systemic anticoagulation are used to ensure catheter patency. At present the most commonly used solutions are either heparin or sodium citrate. According to the literature use of sodium citrate may be advantageous in reducing bleeding events. We report a case of hemorrhagic shock following hemodialysis catheter lock with heparin, reversed after switching solution to sodium citrate.

血液透析导管肝素锁相关出血：隔日失血性休克

导管功能障碍是导管丢失的重要原因。为了防止这种情况，使用全身抗凝风险最小的锁定溶液来确保导管通畅。目前最常用的溶液是肝素或柠檬酸钠。根据文献，使用柠檬酸钠可能有利于减少出血事件。我们报告了一例用肝素进行血液透析导管锁定后的失血性休克病例，在将溶液切换为柠檬酸钠后逆转。
