Optimal Intramuscular Needle-Penetration Depth

The US Centers for Disease Control and Prevention has needle-length recommendations for intramuscular vaccinations in the thigh and shoulder on the basis of the age of the child. Underpenetration of the intramuscular layer with short needles has been documented; however, few studies have focused on the risk for overpenetration of the intramuscular level with needles that are too long. The purpose of this study was to determine the optimal needle length for intramuscular vaccination of children of various ages and sizes at the shoulder and thigh levels by using MRI and computed tomography scan measurements. This article was published in the journal Pediatrics.
