Can you draw a CBC from a heel stick?
The heel-stick method for drawing capillary blood is the most common way to draw newborns’ blood. It is used to collect blood for newborn screening tests, usually before the baby leaves the hospital. Heel sticks are the most commonly performed invasive procedure in neonatal intensive care units.Why is blood taken from a baby heel?
The ‘heel prick test’ is when a blood sample is taken from a baby’s heel so that the baby’s blood can be tested for certain metabolic disorders. The blood sample is taken using an automated device called a lancet. The lancet is used to make a small puncture on the side of the baby’s heel.
Is PKU test necessary?Although PKU is rare, all newborns in the United States are required to get a PKU test. The test is easy, with virtually no health risk. But it can save a baby from lifelong brain damage and/or other serious health problems. If PKU is found early, following a special, low-protein/low-Phe diet can prevent complications.
Article first time published onWhen performing a heel stick the site should be punctured at what angle?
The incision can be placed at a 90º angle to the length of the foot or parallel to the length of the foot. Firmly and completely depress the trigger with your index finger. After triggering the lancet, remove the lancet and discard it into a biohazard sharps container.
How deep should heel sticks be?
The heel puncture should be done on the most medial or lateral portions of the plantar surface of the heel, not on the posterior curvature, to avoid the calcaneous. The lancets are designed to enter no deeper than 2-3 mm. If using a scalpel blade, the blade should enter the skin no more than 2-3 mm.
What is the maximum recommended puncture depth when performing a heel stick on an infant?
Therefore, in order to avoid calcaneal puncture and the risk of osteochondritis, heel puncture in the newborn should be done: (1) on the most medial or lateral portions of the plantar surface of the heel; (2) no deeper than 2.4 mm; (3) not on the posterior curvature of the heel; and (4) not through previous puncture …
Why use of either side of infant's heel and not the center of the heel?
Do not use the center portion of the heel, the arch of the foot, or toes other than the great toe as any of these sites may cause injury to nerves, tendons, and cartilage. Use only approved warming device.
What is the best site for capillary puncture in an infant?
The medial or lateral plantar surface of the heel (Figure 4) is the preferred puncture site for infants up to one year old, including premature newborns. In nearly all infants, the heel bone (calcaneus) is not located below the skin in this area, so the heel bone is protected from injury and related complications.
When taking blood from a newborn baby's heel you should not use a lancet longer than?
Paediatric and neonatal patients In heel-pricks, the depth should not go beyond 2.4 mm. For premature neonates, a 0.85 mm lancet is available.
When performing a dermal puncture Where should the puncture be made?
Perform the puncture on the most medial or most lateral portion of the plantar surface of the heel. Avoid a previous puncture site. Punctures must never be performed on the posterior curvature of the heel, the arch of the foot, or on fingers of a newborn or infant less than one year old.
What is a heel stick?
Heel stick: A simple procedure in which a newborn baby’s heel is pricked and then a small amount of the blood is collected, usually with a narrow-gauge (“capillary”) glass tube or a filter paper. The heel stick is now the most common way to draw newborn’s blood.
Which of the following is an appropriate dermal puncture site for adults?
But what is an appropriate site? 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.
Why do you give babies sugar water?

Do heel pricks hurt babies?
Abstract. Heel prick is a frequent painful procedure in newborns.
Is the heel stick test mandatory?
Almost every child born in the United States undergoes state-mandated newborn screening. For each state, a small blood sample (“heel stick”) is collected from each newborn within 48 hours of birth and sent to a laboratory for testing for a panel of genetic disorders.
When collecting capillary blood from a newborn's heel how far from the puncture site should the tourniquet be applied?
Apply the tourniquet 3-4 inches above the selected puncture site. Do not place too tightly or leave on more than 2 minutes (and no more than a minute to avoid increasing risk for hemoconcentration). Wait 2 minutes before reapplying the tourniquet. The patient should make a fist without pumping the hand.
What are the special considerations for newborn capillary collection?
They can be prevented by using the recommended puncture areas, avoiding the tip of the heel and with the use of proper antiseptic techniques, using a sterile lancet for each puncture and by selecting a new site for each puncture.
Where do you draw blood from a baby under 6 months?
The neonatal heel prick, also known as a dermal puncture, is by far the most popular way to collect blood from newborns and infants up to about six months of age. Dermal punctures are preferable because, when done correctly, they are guaranteed to produce blood, removing the uncertainty of needle sticks.

PKU is a genetic condition, so it can’t be prevented. However, an enzyme assay can be done for people who plan on having children.

M. Warming the skin puncture site: If the finger or heel is cold to the touch, pre-warming the site for a few minutes with a warm compress or commercial heel warmer will increase the flow of blood through the capillary beds. The site should not be warmed to a temperature higher than 42EC.
How long should you observe the site prior to bandaging?
I always perform a two-point check for bleeding before bandaging every patient. I check for bleeding from the skin and also bleeding into the tissue, which can be detected by a raising or mounding of the tissue beneath the puncture when I remove pressure. I take at least 10 seconds to make this observation every time.
