摘要
目的:探讨静脉造影引导及连续X线透视辅助下外周中心静脉置管术(PICC)的应用价值及安全性。方法:将恶性肿瘤长期化疗并进行PICC置管术的患者150例,按随机数字表法分为盲穿组(A组)、超声引导下穿刺组(B组)、静脉造影引导及连续X线透视辅助穿刺组(C组),每组50例,各组均采用巴德公司生产的3项瓣膜式4F PICC导管。结果:一次置管成功率A组为72%,B组为90%,C组为92%,A、B组比较差异具有统计学意义(χ2=5.26,P<0.05);B、C组比较差异无统计学意义(χ2=0.12,P>0.05)。A组并发症的发生率为22%,B组为8%,C组为2%,A、B组比较差异具有统计学意义(χ2=3.84,P<0.05);B组并发症的发生率高于C组,但2组比较差异无统计学意义(χ2=1.89,P>0.05);置管操作时间A组为(12.8±3.1)min,B组为(8.4±1.2)min,C组为(5.2±2.1)min,A、B组比较差异具有统计学意义(P<0.05),B、C组比较差异具有统计学意义(P<0.05)。结论:采用静脉造影引导X线透视辅助下PICC置管术一次置管成功率与超声引导下无差别,但能降低并发症的发生率,减少操作时间。
Objective: To discuss the the safety and application values of PICC catheterization guided by veinography and aided by continuous X-ray fluoroscopy. Methods: All 150 patients who were suffering malignant tumor, undergoing long-term chemotherapy and performing PICC catheterization were divided into blind puncture group(group A), the group of puncture guided by ultrasound(group B), the group of puncture guided by veinography and aided by continuous X-ray fluoroscopy(group C) according to random number table method, 50 cases each group,the patients in different groups used three valves type 4 F PICC catheter produced by Budd Company. Results: The success rates of catheterization once of group A, group B and group C were 72%, 90% and 92%, the difference had statistical meaning when group A was compared with group B( χ2=5.26, P<0.05); the difference had no statistical meaning when group B was compared with group C( χ2=0.12, P >0.05). The incidences of the complications in group A, B and C were 22%, 8% and 2%, the difference showed statistical meaning when group A was compared with group B( χ2=3.84, P<0.05); the incidence of the compilications in group B was obviously higher than that of the group C, while the difference had no statistical meaning when group B was compared with group C( χ2=1.89, P>0.05);intubation operation time of three groups were(12.8±3.1)min,(8.4±1.2)min and(5.2±2.1)min, the difference was statistically significant in the comparison between A and B(P<0.05), there was a significant difference in the comparisons between B and C(P<0.05). Conclusion: There is no difference when the success rate of PICC catheterization once guided by veinography and aided by continuous X-ray fluoroscopy was compared with the rate guided by ultrasound, while catheterization guided by veinography and aided by continuous X-ray fluoroscopy could decrease the incidence of the complications and reduce operation time.
