1. A PROSPECTIVE
RANDOMIZED STUDY TO
ASSESS EFFECTIVENESS
OF ULTRASOUND FOR
PERIPHERAL VASCULAR
ACCESS IN PEDIATRIC
PATIENTS
Presented by ;Mary Teenu

2. Problem statement
A prospective randomized
study to assess effectiveness
of ultrasound for peripheral
vascular access in pediatric
patients.

3. Introduction
• Vascular access in pediatric
patients is often more difficult
than adults because of the
smaller size of the vessels and
non-cooperation. Ultrasound is
an invaluable tool for vascular
access by nurses in this
population

4. Objectives
• To compare overall success rate
of iv insertion in ultrasound and
non ultrasound group
• To compare first IV line insertion
success rate of ultrasound and
non ultrasound group
• To compare average number of
attempts made in ultrasound and
non ultrasound group

5. Objectives
• To compare average needle
redirections in ultrasound and
non ultrasound group
• To compare IV line average
insertion time of ultrasound and
non ultrasound group

6. METHODOLOGY

7. Study design
• Prospective randomized study

8. Population
• Pediatric patients who require
peripheral IV line

9. Site
• All India Institute of Medical
Sciences, New Delhi

10. Setting
• Neurosurgery
ICU, JPNATC, AIIMS

11. Sampling technique
• Simple random sampling

12. Inclusion criteria
• Age <10 years
• Patients who require peripheral
vascular access

13. Study period
• 2 months (1st June- 31st July
2013)

14. Procedure
• Subjects were selected and
assigned randomly to group A
and group B.
– Group A subjects were cannulised
with the use of ultrasound
– Group B were cannulised without
any aid. First insertion success
rate, access time and complications
were compared between the two
groups

15. Ultra sound view of vein

18. Demographic data
Mean age (range)
Group A 6years (5 months to
8years)
Group B 5.2 years (9 months to
10 years)
N =14

19. Demographic data…
Male Female
Group A (n=7) 4 (57.14%) 3 (42.85%)
Group B (n=7) 5 (71.42%) 2 (28.57%)
N =14

20. Overall success rate
Group A (n=7) 6 (85.71%)
Group B (n=7) 4 (57.14%)
N =14

21. First IV line insertion success rate
Group A (n=7) 6 (85.71%)
Group B (n=7) 3 (42.85%)
N =14

22. Average number of attempts
made
Group A (n=7) 1.4
Group B (n=7) 4
N =14

23. Average needle redirections
Group A (n=7) 2.4
Group B (n=7) 5
N =14

24. Average time taken for the
procedure (Range)
Group A (n=7) 2.6 min (2- 5 min)
Group B (n=7) 3.3 min (2.5 - 6 min)
N =14

25. Conclusion
• In a sample of pediatric patients
ultrasound-guided intravenous
cannulation required less overall
time, fewer attempts, and fewer
needle redirections than
traditional approaches. Overall
success rate and first insertion
success rate is more in ultrasound
guided method.
