Skin Pigment/Pulse Oximeter in Congenital Heart Disease (CHD)

Summary

Recent retrospective studies have demonstrated differences between pulse oximeter values (SpO2) and measured arterial oxygen saturation (SaO2) in patients identifying as Black or Hispanic. These retrospective studies have limitations because self-reported race is likely not an accurate metric for level of skin pigmentation and the retrospective nature of these studies may impact the accuracy of simultaneous measures of arterial oxygen saturation and pulse oximeter values. The few prospective studies that have evaluated this issue have utilized color-matching techniques to quantify skin pigmentation, and fewer studies have directly measured skin pigmentation in relation it to pulse oximeter accuracy. The aim of this study is to prospectively measure pulse oximeter accuracy in relation to measured levels of skin pigmentation in the congenital heart disease population.

Eligibility

Inclusion Criteria:

* Pediatric patients (age less than 18 years old) with a diagnosis of CHD (cyanotic or acyanotic) who are presenting for cardiac surgery under general anesthesia with planned arterial access.

Exclusion Criteria:

* Age greater than 18 years old
* Emergency surgery
* Significant preoperative anemia (hemoglobin \<8.0 g/dL)
* Preoperative hemodynamic instability (i.e., \>1 vasoactive infusions or mechanical circulatory support)
* The presence of any colored nail polish on the planned site of pulse oximeter placement, planned use of any intravenous dyes intraoperatively, and patient, parent, or guardian refusal.
