Two-point-one-line pre procedural ultrasound identification and surface localization technique for challenging peripheral venous punctures in children

To investigate the effectiveness of the two-point-one-line pre procedural ultrasound identification and surface localization technique for challenging venous punctures in children. A total of 632 cases utilizing the two-point-one-line pre procedural ultrasound identification and 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. The use of the two-point-one-line pre procedural ultrasound identification and surface localization 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). Adopting the two-point-one-line pre procedural ultrasound identification and surface localization 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.
