Abstract
Objective To explore the effectiveness of a postural assisted fixator in tip positioning of peripherally inserted central catheters(PICC)on the chest of premature infants.Methods A total of 60 preterm infants who underwent upper limb PICC catheterization in Jiaxing Maternal and Child Health Hospital from April to September 2024 were selected as control group,while another 60 preterm infants who received upper limb PICC catheterization from October 2024 to April 2025 were assigned to experimental group.Both groups underwent chest X-ray imaging for catheter tip positioning.The control group was positioned with small sandbags for imaging,whereas the experimental group used a postural assisted fixator.The accuracy of catheter tip positioning,the success rate of single-image positioning,the duration of position fixation during imaging,and the stability of physiological parameters in preterm infants were compared between two groups.Results The success rate of one radiographic exposure with accurate catheter tip positioning in experimental group of preterm infants was higher than that in control group.The time required for position fixation during radiography in experimental group was shorter than that in the control group.The stability of physiological indicators in the experimental group was significantly better than that in control group,with all differences being statistically significant(P<0.05).Conclusion The use of postural assisted fixator for tip positioning of PICC on the chest of premature infants can significantly improve the success rate of catheter tip positioning on the first attempt and reduce the time required for positioning during radiography,thereby enhancing the stability of physiological parameters in premature infants.关键词
