CAPILLARY BLOOD SAMPLING Location The pick-up locations selected for this purpose are: - Fingertips (3 or 4) - Ear lobes - Big toe or heel (in babies) Tools - The tool used to perform the puncture is calledblood lancet. - There are various forms, but the best is of course disposable lancet (disposable lancet). This tool must be sterile and sharp and its piercing power must have a certain depth (- 3 mm). Things that need to be considered - Before carrying out a stabbing, local conditions need to be carefully considered for the presence, - Scars (cicatrix) Signs of - inflammation - Dermatitis or edema, etc. - This situation is a counter indication for taking at that place. You also need to pay attention to the condition of the sufferer's hands, which are pale, cyanotic - they need to be massaged first and rubbed or soaked in warm water so that blood circulation becomes smoother/better. - The pricking of the fingertip should be done at the edge, because in this area there is little nerves so the pain is reduced. - Puncture of the lobe of the ear is generally less painful than piercing of the fingertip and the puncture must be done on the edge as well. If bleeding occurs in the earlobe area, it is difficult to stop. - Therefore, if it is suspected that the patient is suffering from a bleeding disorder, it is best not to inject the ear lobe. - If the patient who is going to be "worked on" is afraid, give an explanation beforehand about what will be done and the benefits, so that the patient becomes cooperative. Work procedures 1) The place to be pierced must first be disinfected with 70% alcohol or other disinfectant, then let it dry. 2) The local skin is tensed by massaging between two fingers. 3) Make a stab. The stabbing should be done quickly but precisely, so that a wound that is about 3 mm deep occurs. 4) Remove the first drop of blood with dry and clean cotton, because this blood is very likely still mixed with alcohol. 5) Use the next drop of blood as a blood sample for examination. Constraint - If the surrounding skin is not dry (wet with alcohol or sweat), taking a blood sample will be difficult because the blood will immediately spread and this blood sample should not be used, because it has been mixed with other ingredients. - If the puncture site is not good or the puncture is not deep enough, the blood will not come out smoothly. Efforts to facilitate blood flow through massage are not justified because the blood sample obtained has been mixed with tissue fluid, resulting in dilution as a result, examinations such as measuring Hb levels or counting blood cell counts will result in lower results.
