Which connector best protects tiny babies from deadly infections?

This study looked at 60 very preterm babies (born before 32 weeks or weighing under 1500 grams) to see which type of needleless connector—split septum or mechanical valve—works better at preventing central line-associated bloodstream infections. Researchers observed the babies for two weeks after the line was placed and took blood samples to check for infection. The goal is to find out which connector leads to fewer infections, shorter hospital stays, and lower death rates.
