Get Capillary Puncture Definition

Capillary punctures require different devices than the typical venipuncture equipment. They include lancets, microcontainer tubes, microhematocrit tubes and sealants, and warming devices.

Introduction. Capillary blood sampling, which refers to sampling blood from a puncture on the finger, heel or an earlobe, is increasingly common in medicine.

Capillary collection should not be performed on adult patients if adequate veins are available and patient is willing to allow their use. Also, capillary collection should be avoided if patient is dehydrated, has edema, or presents with poor circulation to the extremities.

The finger is usually the preferred site for capillary testing in an adult patient. The sides of the heel are only used in paediatric and neonatal patients. Ear lobes are sometimes used in mass screening or research studies.

The skin of the finger, heel, or another area is pricked with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding.

Capillary blood sampling is becoming a common way to minimize the amount of blood drawn from a patient. The 10 or 20 microliters can be used to look for anemia, check blood sugar or even to evaluate thyroid function. The procedure is easier and less painful than traditional venipuncture which draws blood from a vein.

Finger - Usually the third or fourth finger is preferred in adults and children. The thumb has a pulse and is likely to bleed excessively. The index finger can be calloused or sensitive and the little finger does not have enough tissue to prevent hitting the bone with the lancet.

For which of the following patients would a capillary puncture be preferred? A patient requiring frequent blood tests.

Lancets are incision devices meant to puncture or cut the skin to obtain capillary blood. They are specifically designed to be used for finger or heel puncture.

The distal end of the third or fourth finger is the most commonly used site. The very tip of the finger should not be punctured because there is a greater chance of puncturing bone as the bone is close to the skin surface. Puncture the fleshy pad on the end of the finger, slightly off center.

The puncture must be performed on the side of the fingertip where tissue depth is sufficient to prevent bone injury.
