Abstract:Objective To observe the clinical effect of ultrasound-guided double-line isolation and localization technique in infant radial artery puncture. Methods A total of 40 infants who were treated with radial artery puncture were chosen from March 2017 to December 2018 in Beijing Friendship Hospital, Capital Medical University. The patients were divided into control group and observation group through random number table, with 20 cases in each group. The control group was treated with conventional ultrasound-guided radial artery puncture technique, while the observation group received ultrasound double-line isolation positioning technique for radial artery puncture. The primary observation goal was to compare the success rate of the first attempt, and the secondary observation goal was the failure rate of puncture, the time of ultrasound localization, and the incidence of complications. Results The success rate of first intubation in the observation group was 85%, which was significantly higher than that in the control group (55%), the difference was statistically significant (P < 0.05). The ultrasound localization time in the observation group was significantly shorter than that in the control group, the difference was statistically significant (P < 0.05). The incidences of venipuncture failure and bleeding in the observation group were lower than that in the control group, the differences were statistically significant (P < 0.05). Conclusion Ultrasound-guided double-line isolation and localization technique is not only helpful in shortening the ultrasound localization, but also in improving the success rate of the first puncture of radial artery in infants under ultrasound guidance.
