Continuous monitoring of oxygenation in sick newborns is vitally important. However, transcutaneous PO2 measurements have a number of limitations. Therefore, we report the use of the pulse oximeter for arterial oxygen saturation (SaO2) determination in 26 infants (birth weights 725 to 4,000 g, gestational ages 24 to 40 weeks, and postnatal ages one to 49 days). ⋯ However, the differences between measured SaO2 and the pulse oximeter SaO2 were significantly greater in samples with greater than 50% fetal hemoglobin when compared with samples with less than 25% fetal hemoglobin (P less than .001). The pulse oximeter was easy to use, recorded trends in oxygenation instantaneously, and was not associated with skin injury. We conclude that pulse oximetry is a reliable technique for the continuous, noninvasive monitoring of oxygenation in newborn infants.

Optimal emergency care of the child requires a well-developed EMS-C system. The components are easy to identify. We need macroregions with institutions acknowledging their institutional capabilities for pediatric emergency care and supporting field triage and transfer agreements. ⋯ Comprehensive pediatric emergency care involves integration of emergency stabilization patient care with community and hospital social services, patient education programs (such as Child Life), and comprehensive rehabilitation programs, as well as community accident prevention and basic life support programs. As we strive to develop optimal emergency medical services for our country to best serve our people, comprehensive emergency care of children must have separate consideration from comprehensive emergency care of adults. If we are to assure optimal outcome for the life-threatened child, we need to continuously assess regional needs and capabilities and encourage optimal involvement of health care providers and institutions.

Comparative Study
Pulse oximetry in very low birth weight infants with acute and chronic lung disease.
With improved survival of very low birth weight infants, the incidence of bronchopulmonary dysplasia has significantly increased. Pulse oximetry appears to be an adequate alternative to transcutaneous PO2, for continuous arterial oxygen saturation (SaO2) monitoring in neonates; however, its usefulness has not been very well documented in very low birth weight infants. We studied 68 patients with birth weight less than 1,250 g; 44 neonates had respiratory distress syndrome and 24 had bronchopulmonary dysplasia. ⋯ Regression analysis of transcutaneous v arterial PO2 in infants with bronchopulmonary dysplasia showed an r value of .78. In addition, in these patients with chronic disease, the mean difference between pulse oximeter SaO2 and co-oximeter measured SaO2 was 2.7 +/- 1.9% (SD); whereas the mean difference between transcutaneous and arterial PO2 was -14 +/- 10.7 mm Hg. Our findings indicate that pulse oximetry can be used reliably in very low birth weight infants with acute and chronic lung disease, for SaO2 values greater than 78%.(ABSTRACT TRUNCATED AT 250 WORDS)
