The objective of this study was to evaluate subcutaneous microdialysis for long-term glucose monitoring in neonatal intensive care. We determined the relative recovery of the microdialysis system in vitro and in vivo, the stability of the relative recovery in vivo during long-term microdialysis, and the correlation between blood and dialysate concentrations of glucose and urea. Furthermore, we evaluated the sensitivity and specificy of subcutaneous microdialysis for the diagnosis of hypoglycemia.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Patient and Methods.<\/jats:title>\n                  <jats:p>Thirteen infants (10 neonates) with gestational ages of 30.2 to 45.6 weeks were investigated by microdialysis of subcutaneous adipose tissue and blood sampling.

Using urea as the internal standard, the mean relative recovery in vivo was 96.4 \u00b1 12.7% at the beginning and remained constant up to 16 days.<\/jats:p>\n                  <jats:p>The correlation between microdialysate and blood was significant for glucose (r = 0.88) and urea (r= 0.98). Subcutaneous microdialysis allowed the detection of asymptomatic hypoglycemias. The diagnostic sensitivity of a dialysate glucose \u22642.9 mM to predict a blood glucose level \u22642.8 mM was 92.3%, with 88.1% specificy. The positive predictive value with a 13.4% prevalence of a blood glucose \u22642.8 mM was 54.5%, with a negative predictive value of 98.7% and an accuracy of 88.7%.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions.<\/jats:title>\n                  <jats:p>Subcutaneous microdialysis is a safe method, well suited for long-term glucose monitoring in neonates during intensive care.
