Building a Fear-Free SCIg Routine for Your Child With Primary Immunodeficiency


Children’s bodies present some different challenges from adults’ when it comes to where and how to give an infusion. “Fortunately, SCIg needles are tiny compared to IV needles; I often show patients directly the difference in size,” says Platt.

Smaller Bodies, Smaller Sites

“There may be more limited sites, mostly limiting options to the abdomen and thighs,” Platt says. Upper arms and backs, which are options for adults, may not be practical for children, he says.

Rotating sites from one infusion to the next is also important, since using the same spot repeatedly raises the risk of scar tissue, says Platt. If you’re using more than one site, keep them at least 2 inches (5 centimeters) apart.

Needle Placement and Technique

SCIg needles go in at an angle, just under the skin rather than into a vein, and typically measure between a quarter inch and just over a half inch long.

“Pain can indicate that the needle is in too deep. Itching or redness can indicate that the needle is too shallow,” Platt says.

Keep in mind that infusions can take longer than expected if the appropriate tubing is not selected, he adds.

Numbing Options

Before you begin, ask your child’s medical team about numbing medications to reduce pain from the needle, says Platt.

“Lidocaine numbing cream can be used to assist with self-injections,” says Megan Ehret, PharmD, a professor in the department of practice, sciences, and health outcomes research at the University of Maryland School of Pharmacy in Baltimore. “Apply to clean skin about 30 to 60 minutes before the injection, and wipe off before the needle stick.”

Ice or a cold spoon on the site beforehand can also help, if your provider gives the okay, as can devices designed to distract or dull the nerve signals at the injection site, says Dr. Ehret.
