Background: The perfusion index (PI) derived from pulse oximetry readings represents the ratio of pulsatile (arterial blood) and nonpulsatile contributors to infrared light absorption. PI has been shown to correlate with cardiac performance. In theory, PI is readily available on every pulse oximeter; therefore, no additional sensors or infant handling are required. Currently, reference values are lacking in (preterm) neonates and the association with common clinical conditions is unclear. Objectives: To establish reference values for the PI in premature infants and at the same time determine the influence of common clinical conditions. Methods: PI was prospectively monitored on the lower limb for 72 h in 311 neonates born with a gestational age <32 weeks between January 2011 and December 2013. Longitudinal mixed-effects modeling was used. Linear, quadratic, and cubic models were explored. Main effects and interactions were investigated. Results: A squared model (0-24 h) followed by a linear model (24-72 h) provided the best fit of the data. PI was lowest around 12-18 h after birth and showed a steady increase thereafter. PI was positively related with female gender, gestational age, and pulse pressure. Negative associations were found with SIMV/HFOV ventilation, dopamine administration, mean arterial blood pressure, and arterial oxygen saturation. Although more complex, the general association with a patent ductus arteriosus was positive. Conclusion: PI varied according to several clinical conditions. The association with common clinical factors suggests that PI might be used for monitoring neonatal hemodynamics and possibly as an additional guidance for interventions.

Hemodynamic monitoring on the background of intensive therapy in newborns

The article deals with the problem of early neonatal and infant mortality. It is pointed out that recent advances in emergency and intensive care therapy have provided decline in early neonatal and infant mortality. Hemodynamic disorders are reported to be associated with any severe pathology in patients of all age groups including newborns, significantly influence quality of life of patients having experienced a critical condition. Clinical manifestations of hemodynamic disorders in infants are not considered to be specific; they are critically delayed and are not timely recognized. The article describes peculiarities of the cardio-vascular system of newborns that are responsible for the necessity of thorough hemodynamic profile monitoring in order to provide detection of vital function alterations at the early stages, ensure timely onset of intensive therapy and its qualitative performance. Special attention is paid to current methods of determination of central hemodynamic parameters, which are stated to be divided into invasive and non-invasive. The paper also highlights some peculiarities of evaluation of hemodynamic findings using specific monitoring methods and factors influencing the outcome. The article specifies increased interest towards non-invasive monitoring tools of hemodynamic profile in recent years; their relevance is stated to be doubtless in both pediatric and neonatal practice. The main task of any monitoring procedure is reported to be hemodynamic findings analysis, “trend tracking” in the process of monitoring a patient and intensive therapy performance.
