ABSTRACT
Objective To explore the feasibility of the double venipuncture instead of central venous catheter as a temporary vascular access in hemodialysis.Methods The upper arm below the 1/3 was tied a tourniquet,and fistula needle directly punctured the vein in the middle of the elbow.After the success of the puncture,elastic bandage was replaced by a tourniquet,and the ball movement was done by imitating the blood donation member for blood donation at hand gripping a ball or elements as the artery blood lead.Another elbow vein or lower limb saphenous vein was punctured.Thirty patients using double venipuncture dialysis or central venous catheter dialysis 2 weeks or more were randomly selected into each group,and biochemical and renal function was measured before dialysis.Results All of 1 282 patients who were newly into the blood dialysis,mature arteriovenous fistula was in 8 patients (0.6％,8/1 282),deep venipuncture to insert the central venous catheter was in 542 patients(42.3％,542/1 282),using the double venipuncture was in 732 patients (57.1％,732/1 282).The flow of blood was 180-200 ml/min,the avalible time was 1-2 months.The serum creatinine,blood urea nitrogen,calcium,phosphorus and carbon dioxide combining power had no significant difference between two groups (P ＞ 0.05).Conclusions The majority of patients with double venipuncture blood flow can satisfy the need of dialysis.Because the operation is simple,no recycling and may reduce the deep venipuncture,it is an ideal temporary vascular access.
