Objective: Arterial cannulation is a useful skill for doctors working in anaesthesiology and critical care. In paediatrics, arterial cannulation is arduous due to the small calibre of artery. In neonates, it becomes even more challenging. In this study, we compared the success of real-time ultrasound guided arterial cannulation with that of traditional palpation technique.
Study Design: Prospective Comparative Study.
Place and Duration of Study: Pak Emirates Military Hospital, Rawalpindi Pakistan, from Jul 2020 to Oct 2021.
Methodology: We included eighty neonates scheduled for major surgery under general anaesthesia. They were divided randomly into two Groups, each Group comprising 40 patients. In ‘Group A’ arterial cannulation was performed using real-time ultrasound guidance while in ‘Group B’ palpation technique was used. The primary outcome of our study was number of attempts until successful arterial cannulation. Secondary outcome of study was number of complications (thrombosis, haematoma).
Results: In this study, a total of 80 neonates were enrolled. There was no difference in demographic data comparison. First attempt success rate in imaging Group was considerably higher 33(82.5%) versus 21(52.5%) with p-value of <0.001. Neonates in ultrasound Group required a smaller number of attempts (1.38±1.005) than in palpation Group (4.00±1.396) for successful cannulation (p-value<0.001).
Conclusion: We concluded that real-time ultrasonography guidance is more successful than palpation technique for arterial cannulation.
