Effects of age, sex and body anthropometry on needle thoracostomy in a Singapore paediatric cohort: a chest CT study

Listen to this summary

The authors aimed to investigate how age, sex, and body anthropometry influence chest wall thickness (CWT) at common needle thoracostomy (NT) landmarks in a pediatric population, as well as to assess the adequacy of needle lengths used for the procedure. Through a retrospective review of chest CT scans from children aged 0-17 years, they found that CWT varies significantly by age and recommended specific needle lengths for successful NT: 25 mm for infants, 32 mm for children, and 50 mm for adolescents.
