"Two-Point-One-Line" Ultrasound Surface Localization for Challenging Peripheral Venous Punctures in Children

Abstract 【Objective】 To investigate the effectiveness of the "Two-Point-One-Line" ultrasound surface positioning technique for challenging venous punctures in children. 【Methods】 A total of 632 cases utilizing the "Two-Point-One-Line" ultrasound surface positioning technique were compared with 628 cases using conventional ultrasound guidance in children with difficult peripheral venous access. The comparison focused on the first puncture success rate, puncture duration, puncture-related complications (including subcutaneous hematoma, phlebitis, and pain), and patient satisfaction. 【Results】 The use of the "Two-Point-One-Line" ultrasound positioning technique for challenging venous punctures in children significantly improved the first puncture success rate (P < 0.005), reduced puncture duration (P < 0.005), and decreased complications such as subcutaneous hematoma, phlebitis, and pain (P < 0.005). Furthermore, both children and their parents reported higher satisfaction (P < 0.005). 【Conclusion】 Adopting the "Two-Point-One-Line" ultrasound surface positioning technique for difficult venous punctures in children can improve the first puncture success rate, shorter puncture duration, reduce complications, and enhance the satisfaction of both children and parents.
