Rapid central venous catheterization is critical for the rescue and perioperative management of premature infants requiring surgery. Ultrasound‐guided dynamic needle tip positioning (DNTP) has been widely used as a very effective technique, especially in paediatric vascular puncture and catheterization. However, for low‐weight premature newborns, central vein catheterization still poses greater difficulties for paediatricians and paediatric anaesthesiologists. This prospective randomized control study aimed to evaluate the efficacy of combined short‐ and long‐axis (CSLA) internal jugular vein catheterization for premature newborns in comparison with the DNTP technique.
