Study Notes
Comparison of Arterial, Venous, and Capillary Blood Gas Values in Pediatrics
- Out of 2,502 articles, 92 articles underwent full-text review and 26 studies met the inclusion criteria.
- The reliability of venous and capillary blood gas values as surrogates for arterial blood gas values must be established before clinical use.
- Limited studies address the reliability of alternative blood gas sampling methods in pediatrics across different age groups.
- No studies were found that compared arterial versus venous blood gas results in preterm infants admitted to a neonatal ICU.
- Studies evaluated differences in arterial and arterialized capillary blood gas values in neonates and children.
- McLain et al. reported that arterial and arterialized capillary pH and PCO2 satisfactorily represented arterial values.
- Saili et al. found statistically significant differences for all blood gas values when comparing arterialized capillary blood with arterial blood specimens in preterm neonates.
- Yang et al. noted significantly higher PaO2 and arterial oxygen saturation in arterial samples compared with heel puncture samples in infants.
- Four clinical studies evaluated differences in arterial and capillary blood gas values, some including a comparison with samples from a peripheral vein.
- The impact of pre-analytic errors on blood gas and pH errors, collection technique on patient complications, and handling of blood obtained from capillary sites were addressed in the studies.
- Various studies compared capillary blood gas samples with arterial or venous samples, warmed and unwarmed heel capillary samples, and sample delivery methods.
- The systematic review provided a summary of evidence for each PICO question addressed in the study.
