Primolut And Breastfeeding
blood extraction is a very common medical procedure for the detection of possible diseases to perform the necessary analysis of the blood sample. Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand.
The puncture site is cleaned with antiseptic and an elastic band or a pressure cuff around the upper arm to apply pressure and restrict blood flow through the vein, making veins below the band to widen. Immediately thereafter, inserts a needle into the vein and the blood is collected into an airtight vial or a syringe.
During the procedure, the band is removed to restore circulation, once blood has been collected, the needle is removed and the puncture site is covered to stop any bleeding. Depending on the type of analysis to be performed is required to have suspended food consumption at least eight hours before extraction, although this case always has to determine the physician at the time of requesting the test.
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Subsequently, there may be some throbbing. Some people may experience dizziness or fainting due to the impression that they cause, so we recommend sitting or lying down during extraction.
