Abstract:
The authors show the relationship between the use of physical contact and the decrease in pain during venipuncture, or blood-drawing, by means of a clinical test and an experimental, random, controlled study. Random sample by means of a systematic probability sampling. Two groups, control and experimental, were set up, employing physical contact in the latter group. To measure pain, an Analogical Visual Scale from 0-10 (EVA 0-10) was used and a data-register sheet was developed. Pain decreased by 37.45% (p = 0.000) in the experimental group, one of the main objectives of this study.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
