改进导丝置入法在超声引导下P ICC置管中的应用

Application of improved guide wire placement method in PICC catheter guided by US

目的：探讨改进导丝置入方法的超声引导下改良塞丁格技术行PICC置管,与常规超声引导下改良塞丁格技术行PICC置管的应用效果。方法选择2014年1月—2015年12月于宣武医院普通外科置管的120例患者,按随机数字表法分为对照组和观察组各60例。对照组患者采用超声引导下改良塞丁格技术置管,观察组患者采用改进导丝置入方法后超声引导下改良塞丁格技术置管。比较两组一次导丝置入成功率及导管相关并发症发生率。结果观察组一次导丝置入成功率明显高于对照组（χ2＝11.582,P〈0.05）；两组静脉炎、血栓发生率差异无统计学意义（ P〉0.05）。结论改进导丝置入方法的超声引导下改良塞丁格技术置管,较常规超声引导下改良塞丁格技术置管一次导丝置入成功率大大提高。

Objective To explore the application effect between ultrasound （ US）-guided central line insertion combined with modified guide wire insertion technique and the conventional US-guided peripherally inserted central catheter （ PICC） placement. Methods Totally 120 cases with PICC from January 2014 to December 2015 in Departwent of General surgery were randomly divided into the control group and the observation group. Patients in the control group received conventional US-guided PICC line placement, while patients in the observation group received US-guided central line insertion combined with modified guide wire insertion technique. The success rate and the incidence of complications related to catheter were compared in two groups.Results A statistically difference suggested that the success rate in observation group was significantly higher than the control group （χ2 =11. 582, P〈0. 05 ） . Differences of the incidence of phlebophlogosis and thrombus in two groups weren′t significant（P〉0.05）.Conclusions US-guided central line insertion combined with modified guide wire insertion technique has a higher successful rate compared to the conventional US-guided PICC line placement.
