Application of ultrasound-guided dynamic needle tip positioning technique in peripheral venous catheterization in children with venipuncture difficulties
Objective To investigate the application effect of ultrasound-guided dynamic needle tip positioning technology in peripheral venous catheterization in children with venipuncture difficul-ties.Methods A total of 60 children who underwent laparoscopic hernia repair under elective gener-al anesthesia in Subei People's Hospital of Jiangsu Province from August 2022 to August 2023 were enrolled.The children were divided into control group(30 cases,group C)and ultrasound-guided dynamic needle tip positioning group(30 cases,group U)by random number table method.After se-dation,the children in group C received the traditional peripheral venous puncture and catheterization to open the peripheral venous access,while the children in group U were sedated and received ultra-sound-guided dynamic needle tip positioning technology to guide the peripheral venous puncture and catheterization to open the peripheral venous access.The success rate of the first venous puncture,the success rate of catheter placement,the time of catheter placement,and occurrence of complica-tions werecompared between the two groups.Results Compared with group C,the success rate of first puncture and catheter placement in group U were significantly increased,and the time of catheter placement was significantly shortened(P＜0.05).After puncture,subcutaneous congestion occurred in 5 children in group C and 2 children in group U,but there was no statistical significance in the in-cidence of subcutaneous congestion between the two groups(P＞0.05).Conclusion Ultrasound-guided dynamic needle tip positioning technology can significantly improve the success rate of peripher-al venous catheterization and shorten the time of catheterization in children with venipuncture difficulties,which has certain clinical significance for reference.
