Correlation of Venous and Arterial Blood Gas Values Following Cardiothoracic Surgery in Infants and Children

Abstract

Intermittent measurement of arterial blood gases is and arterial blood gas values following cardiothoracic surgery commonly performed to assess the adequacy of in infants and children.

Study of Correlation of Arterial Blood Gas Measurements with Peripheral Venous Blood Gas Values in Adult Patients Admitted in ICU in Tertiary Care Hospital in Central India – A Cross-Sectional Study

“…In this regard, various studies have been reported on children and adults to investigate the accuracy and efficacy of VBG analysis versus ABG. [5,6,[11][12][13][14][15][16] In a study carried out by Kelly, the venous and arterial pH showed a high degree of correlation (r = 0.92) and with an average difference between the samples of −0.04 units. [13] In the present study, the venous and arterial pH showed a high degree of correlation (r = 0.90) and with an average difference between the samples of 0.03 ± 0.20 which is correlated with the other studies.…”

Correlation of Lactic Acid and Base Deficit Values Obtained From Arterial and Peripheral Venous Samples in a Pediatric Population During Intraoperative Care

“…In such circumstances, it has been demonstrated that there is a strong correlation between central venous and arterial values. [1][2][3][4] However, in the early phases of resuscitation and other specific clinical scenarios, it is feasible that neither arterial nor central venous access may be present.…”

“…In the adult patient in the ICU or emergency department setting, a clinically acceptable correlation has been noted between pH, BD, and lactic acid when comparing venous and arterial samples. [1][2][3][4] However, there are no studies evaluating intraoperative correlations and limited data in the pediatric population regarding the correlation of peripheral venous and arterial values. The current study evaluated the correlation of arterial and peripheral venous values of lactic acid and BD during intraoperative care in a cohort of pediatric patients.…”
