Patients appreciate nurses who can rapidly and accurately perform venipuncture without requiring additional needle sticks. The area where the blood is to be drawn from is first cleaned with a germ-killing solution. Step 1: Identify The Vein The first step in drawing blood correctly is to identify the appropriate veins to puncture. Our present findings can assist nurses to improve current practice by providing knowledge based on anatomical investigation using ultrasonography. How To Do Venous Blood Sampling - MSD Manuals In this kind of transection injury, ultrasound can detect discontinuation of the nerve, showing interruption of the epineurium and enlarged, hypo-echoic nerve stump. We also discuss the importance of ultrasonography for the early diagnosis and prompt treatment of nerve injury following venipuncture. Label all your vacuum tube samples immediately to avoid any possible confusion. Previous studies using anatomical observations reported that fewer cutaneous nerves crossed the superficial layer of the radial median cubital vein, whereas the brachial artery was distributed in the aponeurosis deep layer along this vein,11 and it passed deeply under the unification part of the basilic and median cubital veins and deeply along the ulnar side of the median cubital vein.2,3 Moreover, a previous study reported that the distal superficial vein from the cubital fossa line needs to be punctured to avoid penetrating the vein.11 Therefore, these findings and the present results indicate that the median cubital vein at the cubital fossa is suitable for venipuncture2,3,11 when it is difficult to puncture the cephalic vein. If correctly inserted, blood should flow into the vacuum tube. Avoid venipuncture on the dorsal aspect of the wrist. An official website of the United States government. Therefore, the aim of the present study is to identify safe and suitable venipuncture sites for nursing in the clinical setting using ultrasonography to measure the depth and cross-sectional area of each superficial vein before and after tourniquet application as well as the distance between each superficial vein and the median nerve or brachial artery. It also makes it less painful for the patient. If you see and feel the vessel pulsating after you apply the tourniquet, you're over, 21.

Direct puncture or compression may cause nerve damage. In the present study, the basilic vein had a lower visible rate and smaller vein area than the median cubital vein; however, no significant change was detected in the depth of the basilic vein before and after tourniquet application, and it was not as distant from the median nerve and the brachial artery as the cephalic vein.

The present study had limitations. When puncturing the cephalic vein is difficult because it is not visible, the median cubital vein at the cubital fossa is selected for venipuncture because of its cross-sectional area and visibility; however, care is needed to avoid penetrating the vein because the median nerve and brachial artery are present underneath. The use of ultrasound to identify veins for peripheral venous access in morbidly obese patients. Median cubital vein connects the basilic and cephalic veins in the antecubital fossa. The intensity of the pain was rated as 8/10 in the visual analog scale (VAS). When taking blood, the needle is attached to vacuum tubes to hold the collected blood.

Venipuncture is a medical procedure performed to collect venous blood specimens by physicians, nurses, and medical technologists, with the cubital fossa frequently being selected as the venipuncture area to collect venous blood specimens.13 However, relatively rare, but potentially serious complications including nerve injury (1/21000,4 1/25000,5 1/30923,6 1/670007) and mistaken arterial punctures (1/340008) have been reported.

The visible rate of each superficial vein before and after tourniquet application was 65% (13/20) to 65% (13/20) for the basilic vein, 90% (18/20) to 95% (19/20) for the median cubital vein, and 65% (13/20) to 80% (16/20) for the cephalic vein.
