二维实时超声引导下深静脉穿刺置管对导管相关性感染发生率的影响

目的 探讨二维实时超声引导下深静脉穿刺置管对导管相关性感染发生率的影响.方法 选择2014年8月至2015年12月期间深圳市人民医院ICU收治的300例深静脉穿刺置管的危重症患者为研究对象,根据随机数表法分为观察组与对照组,每组150例,对照组患者采用体表标志定位进行穿刺置管,观察组患者则在二维实时超声引导下进行,比较两组患者的深静脉穿刺置管相关指标.结果 观察组患者的穿刺时间为(6.16±2.38)min,明显短于对照组的(7.89±3.16)min,一次穿刺成功率及导管留置时间分别为97.33％和(13.54±4.18)d,均高于对照组的88.67％和(10.72±3.27)d,导管相关性感染发生率为4.67％,明显低于对照组的10.67％,差异均有统计学意义(P<0.05).结论 二维实时超声引导深静脉穿刺置管能有效提高穿刺成功率,减少穿刺时间,进而减少危重患者导管相关性感染的发生风险.

Effect of real-time two-dimensional ultrasound-guided deep venous catheterization on the catheter related infection

Objective To investigate the effect of real-time two-dimensional ultrasound-guided deep venous catheterization on the catheter related infection. Methods A total of 300 cases of deep venous catheterization patients, who admitted to ICU of our hospital from August 2014 to December 2015, were selected and divided into the observa-tion group and the control group according to the random number table method, with 150 cases in each group. The deep vein catheter in the control group was placed by landmark positioning puncture, and the observation group was carried out by real-time two-dimensional ultrasound. The related indicators of deep venous catheterization in the two groups were compared. Results The puncture time in observation group was (6.16±2.38) min, which was significantly shorter than (7.89 ±3.16) min in the control group (P<0.05). The success rate of one-time puncture and catheter indwelling time were respectively 97.33％and (13.54 ± 4.18) d, which were significantly higher than 88.67％and (10.72 ± 3.27) d in the control group (P<0.05). The catheter related infection rate in the observation group was 4.67％, which was significantly lower than 10.67％in the control group (P<0.05). Conclusion The real-time two-dimensional ultrasound-guided deep venous catheterization can effectively improve the success rate of puncture, reduce the puncture time and the risk of cath-eter-related infection in critically ill patients.
