A novel technique (modified short-axis out-of-plane [MSA-OOP]) to improve first pass success rate of ultrasound-guided IJV CVC in neonates and infants is being compared with conventional SA-OOP method” Rastogi et al (2018).
Abstract:
BACKGROUND AND AIMS: Central venous cannulation (CVC) through right internal jugular vein (IJV) route is routinely performed in paediatric patients undergoing major surgery and in those admitted to intensive care units. A novel technique (modified short-axis out-of-plane [MSA-OOP]) to improve first pass success rate of ultrasound-guided IJV CVC in neonates and infants is being compared with conventional SA-OOP method.
METHODS: A total of 120 patients were enroled in the study over a period of 6 months. All paediatric patients with age <1 year and weight <10 kg who underwent a major surgery requiring CVC were included. Patients were randomised to either of the two approaches of ultrasound-guided IJV cannulation; SA-OOP and modified SA-OOP (MSA-OOP). In modified approach, the midline of probe footprint was marked with a radio-opaque barium wire that casted a central acoustic shadow on ultrasound screen.
RESULTS: In MSA-OOP group, 83.1% of patients were cannulated in the first attempt as compared to 49.2% patients in group SA-OOP. Patients in MSA-OOP group required significantly fewer attempts for successful CVC as compared to patients in the SA-OOP group ( MSA-OOP: median = 1, interquartile range [1-1]; SAOOP: median = 2, interquartile range [1-2], P < 0.001, Mann-Whitney U-test).
CONCLUSION: The use of MSA-OOP ultrasound technique for IJV CVC cannulation results in a higher first-attempt success rate and reduces the number of cannulation attempts.
