在全静脉营养中外周静脉穿刺中心静脉置管的临床应用

目的 :比较在全静脉营养中经外周中心静脉置管 (peripherallyin sertedcentralcatheters,PICC)和中心静脉置管 (CVP)的临床效果。方法 :随机选择需长期静脉营养的患者 6 0例 ,分为两组 ,实验组用PICC ,对照组用CVP ,比较成功率 ,操作时间 ,留置时间 ,液体流速 ,并发症发生率以及导管的细菌培养情况。结果 :一次置管成功率 ,PICC为 93 33% ,CVP为83 33% (P <0 0 5 )。操作时间 ,PICC为 14min ,CVP为 2 3min (P <0 0 1)。留置导管时间 ,PICC平均为 4 6d ,CVP平均为 31d (P <0 0 1)。液体最大流速 ,PICC为 2 5 6ml/h ,CVP为 5 2 7ml/h (P <0 0 1)。并发症 :PICC为 6 6 6 % ,CVP为 16 6 6 % (P <0 0 5 )。导管细菌培养阳性率 ,PICC为 3 33% ,CVP为 16 6 6 % (P <0 0 1)。结论 :PICC较CVP操作简单、快捷 ,成功率高 ,留置时间长 ,并发症少 ,导管阳性率低。虽然液体流速PICC较CVP慢 ,但能满足全静脉营养的要求

Clinical application of Peripherally inserted central catheter (PICC) in total intravenous nutrition

Objective:To compare clinical effect of PICC and CVP in total intraveinous nutrition.Method:60 cases had been randomly divided into 2 groups,PICC had been applicated in experiment group,while CVP in control,successful rate,manipulatory time intubalation time,flow speed,complication incidence,bacterial culture in catheters had been compared between two groups.Result:One time successful rate:PICC,93.33%,CVP,83.33%(P<0.05);manipulatory time:PICC 46 days or so,CVP 31 days or so(P<0.01);flow speed:PICC,256ml/h,CVP,527ml/h(P<0.01);Complication incidence,PICC,6.60%,CVP,16.66%(P<0.05);Positiverate of culture,PICC,3.33%,CVP,16.66%(P<0.01).Conclusion:PICC is simple,easy to grasp,with longer intublation time and less complication,can meet total intraveinous nutrition need.
