ShotBlocker During Intramuscular Injection Randomized Control Trial

The objective of this trial is to evaluate the effect of Bionix ShotBlocker on pain of injection of the first Hepatitis B vaccine in healthy newborns. ShotBlocker is a pain reducing tool used in babies, children, and adults for injections. Swaddling during the injection and administration of oral sucrose prior to the injection are established standards of care for painful procedures in neonates. The investigators hypothesize that the use of ShotBlocker in addition to swaddling and oral sucrose administration will lessen the pain response.

Treatment and study plan

Bionix ShotBlocker

Device

This is a hospital-approved device used as standard-of-care in older children and adults to reduce pain during painful procedures. It is not considered established standard-of-care in the infant cohort.

Primary outcomes

  1. Difference in the heart rate before, during, and after Hepatitis B vaccine injection between the control and intervention groups.

    Time frame: up to 4 minutes

    The primary outcome measure is the difference in the physiologic response before, during, and after the injection between the control and intervention groups as reflected as heart rate. Difference in heart rate will be evaluated through the measurements of heart rate recorded by a Masimo Rad-97 Oximeter.

  2. Difference in the blood oxygen saturation before, during, and after Hepatitis B vaccine injection between the control and intervention groups.

    Time frame: up to 4 minutes

    The primary outcome measure is the difference in the physiologic response before, during, and after the injection between the control and intervention groups as reflected by blood oxygen saturation. Difference in blood oxygen saturation will be evaluated through transcutaneous measurements recorded by a Masimo Rad-97 Oximeter.

Secondary outcomes

  1. Difference in pain score before, during, and after Hepatitis B vaccine injection between the control and intervention groups.

    Time frame: up to 3 minutes

    The secondary outcome measure is the difference in the pain score using the Premature Infant Pain Profile (PIPP) before, during, and after injection between the control and intervention groups. PIPP scores range from 0 to 15 and a lower score indicates a better outcome. For example, a PIPP score of 0 indicates no pain. There will be an Opt-In Video Recording option to assign a PIPP score before, during, and after vaccine administration. Infant response will be filmed during injection and evaluated by a blinded medical professional that did not participate in study procedures to assign a PIPP score.
