Toe temperature may aid noninvasive cardiac index assessment in postoperative infants; leaves open prospective validation before changing practice.
Observational (n=56)
Does big toe skin temperature correlate with cardiac index in infants after open heart surgery?
Effect estimate: r = 0.80
p-value: p=<0.001
Big toe skin temperature is a reliable, simple clinical indicator that correlates strongly with cardiac index in infants recovering from open heart surgery.
Alexi-Meskhishvili et al. (1984) conducted an observational in Infants after open heart surgery (n=56). Big toe skin temperature was evaluated on Correlation of big toe skin temperature with cardiac index (r = 0.80, p=<0.001). Big toe skin temperature correlated well with the magnitude of the cardiac index (r = 0.80, p < 0.001) in infants during the first 24 hours after open heart surgery.
