Mean fluid bolus times by syringe size with 95% confidence intervals (primary outcome analysis). Significant difference between 10 mL and 30/60 mL syringe size groups is clearly demonstrated. There is a notable trend of superiority between of the 30/60 mL groups over the 20 mL group, but this did not achieve significance. This trend provides empirical validity to PALS recommendations suggesting use of 35–60 mL syringes for optimal fluid resuscitation .
