Non Dilation on the Central Venous Catheterization（NDCVC-01）

The central venous catheter is widely used and used in high dosage, and various complications such as hematoma, hemopneumothorax and arterial puncture may occur during puncture and use. In addition to conventional techniques, studies have been done to improve the success rate of puncture and reduce the incidence of complications by modifying different procedures. However, among the complications caused by the procedure of percutaneous catheter placement, the fatal bleeding caused by skin dilation may threaten the patient' s life. There are few studies on dilators and skin dilation steps at home and abroad. In this study, the conventional puncture technique was improved and the skin dilation step was omitted, hoping to reduce complications, reduce puncture time, improve efficiency and improve patient comfort on the premise of ensuring the success rate of catheterization.
