Effects of vascular morphological features and ultrasound-guided vascular cannulation techniques on the success of femoral artery catheterisation in newborns

Frequency and risk factors of acute and permanent femoral arterial occlusion in neonates with congenital heart disease who undergo ultrasound˗guided femoral arterial access

“…2,5 We obtained a high success rate of 98.8% and a very high first attempt success rate of 88.2% compared to previous studies. 2,5,6,11,20 There was no significant difference in first attempt access between patients with and without ALAP, and between patients with PFAO and those without PFAO. A high first attempt access results in a shorter arterial access time and a minimum number of attempts.…”

“…Femoral arterial diameter in neonates was measured as 2.64 ± 0.85 (1.2-4.5) mm in LAX. 5 Among patients with arterial diameters of < 3 mm, the frequency of ALAP was 25% compared to 1.8 % in those with diameters of > 3 mm. 7 Due to the nature of newborn patients, they have risk factors including small age, low body weight, and <3 mm femoral arterial diameter, which are the most important risk factor for femoral artery occlusion.…”

“…We found that the incidences of haematoma and inadvertent puncture were quite low (2% vs.10.6%) when compared to a study of neonate with femoral artery access. 5,6,12 The first attempt success in US-GFAA was reported to be between 25% and 53% in neonates. 2,5 We obtained a high success rate of 98.8% and a very high first attempt success rate of 88.2% compared to previous studies.…”

“…[2][3][4]10,11 Previous studies have shown that ultrasound-guided vascular access (US-GVA) increases the success rate and first attempt success rate and decreases failure rate, number of attempts, vascular access time, and vascular arterial complications. 5,7,[10][11][12] Although the evidence level of US-GVA was classified as 1B for vessel cannulation in adults, no level of evidence has been reported for FAA in children. 10 There are limited data on acute loss of the arterial pulse (ALAP) and permanent femoral arterial occlusion (PFAO) in neonates with congenital heart disease (CHD).…”
