Four different the cuffed central venous catheter methods and analysis

Abstract

Objectives To Observe the four different methods of cuffed central venous catheter and clinical analysis. Methods All 132 patients underwent cuffed central venous catheterization, who were divided into group A (36 cases) of the avulsed sheath placement cuffed central venous catheter, group B (36 cases) of external jugular vein placed catheter, group C (32 cases) of placement catheter directly by direction of wire and after expansion layer by layer and group D (28 cases) of internal jugular vein incision. Results There were no significant differences in creatinine, urea nitrogen level before and after dialysis of four groups and urea clearance index were both standard. There were no the significant differences in blood flow, blood return venous pressure , urea clearance index and catheter retention time of three groups(group A、B、D). There were no significant differences in above index of group A、C. There were no bleeding and infection related complications in four groups after operation, but one case of catheter ectopic occurrence in group B and group C. Conclusions Classic avulsion sheath catheter method is as the preferred for cuffed catheter central venous catheter insert method, and it is a safe and high successful method with less complications. The second method is the internal jugular vein catheter incision, through the guide wire and expansion layer by layer placed catheter, it is suitable for patients with loose subcutaneous tissue , less fat layer. The internal jugular vein incision method in the cuffed central venous catheter is the remedy method for clinical puncture failure without ultrasonic guide, but this method is needed higher technology with high operation risk, not as the clinical first choice.
