Methods for the prevention of internal jugular vein malposition of peripherally inserted central catheter in patient with limited neck motion / 中华临床营养杂志

Objective To evaluate the methods for the prevention of internal jugular vein malposition of peripherally inserted central catheter (PICC) in patient with limited neck motion.Methods 210 patients who underwent PICC placement using ultrasound-guided modified Seldinger technique were divided into observation group (n =106) and control group (n =104) with a random number table.Ultrasound probe compression on the internal jugular vein was used in the observation group,while finger compression was used in the control group.The 2 groups were compared in terms of incidence of internal jugular vein malposition,accuracy of PICC tip position in X-ray,and incidence of complications.Results Incidence of PICC malposition was significantly lower in the observation group than the control group [3 (2.8％) vs.36 (34.6％),P =0.000].The accuracy of PICC tip position in both groups was 100％.No complication was observed in the observation group,while the rate of complication in the control group was 4.8％,with a statistically significant difference (P =0.022).Conclusion The ultrasound probe compression method can significantly lower the incidence of internal jugular vein malposition of PICC and is safer than the finger compression method.

Common problems and countermeasure of ultrasound-guided modified Seldinger technique for peripherally inserted central catheter placement / 中华临床营养杂志

Objective To investigate the common problems and countermeasure of using ultrasound-guided modified Seldinger technique in peripherally inserted central catheter (PICC) placement Method The clinical data of 140 patients who underwent PICC placement using ultrasound-guided modified Seldinger technique were retrospectively analyzed. Results The success rate of catheterization was 98. 6% among these 140 patients,with 135 (96. 4% ) succeeded after a single attempt and 5 (3. 6% ) after 2 attempts. Besides, 7. 1% (n = 10) had difficulty in inserting the guide wire, 3. 6% (n =5) had difficult catheteration, 2. 1% (n =3) met resistance when inserting catheter into ipsilateral subclavian vein, 2. 1 % (n = 3 ) experienced dystopia of inserting catheter into internal jugulular vein, and 1.4% (n = 2) experienced the bending of PICC in the superior vena cava and axillary vein. All of these problems were handled successfully. Conclusions The common problems of PICC placement include puncture failure, difficulty in inserting guide wire, and difficult catheteration. A good knowledge of these problems will help increase the success rate.
