The application of different approach for central venous catheterization

Objectives: To compare the different approach for cetral venous catheterization(CVC). Methods: The disposable peripherally inserted central catheter(PICC) and the single lumen central venous catheter were used. Patients needing long time iv therapy were enrolled in the study. There were 240 patients in two groups( n =120:120).In Group A, the single lumen central venous catheters were placed into superior vena cava via subclavian vein.And in Group B, PICCs were placed into superior vena cava via peripheral vein. Results: ①Success rate: 97.5%(117/120) for PICC and 100%(120/120) for CVC. ②No pneumothorax or hemothorax in PICC group while 1 case (0.83%) of pneumothorax was found in CVC group. ③Catheter translocation happened in 10 cases (8.33%) in PICC group and 1 case (0.83%) in CVC group. ④Phlebitis was noticed in 2 cases (1.67%) in PICC group but none in CVC group. ⑤Catheter occlusion rate: 14.17% for PICC and 7.5% for CVC.Conclusions: PICC is safe and can partly substitute the central catheterization via subclavian venous access.
