【摘要】：正建立中心静脉通路在临床上具有重要意义,临床多选用右侧颈内静脉穿刺。传统的颈内静脉穿刺插管径路很多,但并发症也较多,如误伤动脉、神经及气胸、血胸、血肿和导管位置异常等发生率可高达10%,颈内静脉置管失败率可超过19%[1]。因此,提高颈内静脉穿刺成功率,减少其并发症的发生率非常重要。研究表明[2],在麻醉后使用呼气末正压可以提高颈内静脉充盈度,从而提高穿刺成功率;但对于清醒患者能否通过Valsalva动作提高患者颈内静脉的充盈度,进而有利于穿刺成功率,尚未见文献报
[Abstract]:The establishment of central venous access is of great clinical significance, clinical use of the right internal jugular vein puncture. There are many traditional internal jugular vein catheterization paths, but there are also many complications, such as accidental injury of artery, nerve and pneumothorax, hematoma and abnormal location of catheter, etc. The failure rate of internal jugular vein catheterization can exceed 19% [1]. Therefore, it is important to improve the success rate of internal jugular vein puncture and reduce the incidence of complications. The results show that [2] after anesthesia, positive end-expiratory pressure can improve the filling degree of internal jugular vein, thus increasing the success rate of puncture. However, whether the awake patients can improve the filling degree of internal jugular vein through Valsalva, which is beneficial to the success rate of puncture, has not been reported in the literature.
