Perfusion index and pleth variability index in the first hour of life according to mode of delivery

Özet

Perfusion index (PI) is a relative assessment of the pulse strength at themonitoring site. The plethysmographic variability index (PVI, pleth variabilityindex) is a noninvasive and continuous measure of the dynamic change inPI that occurs during respiratory cycles. In this study PI and PVI changeswere compared in babies born with cesarean section (C/S) or spontaneousvaginal delivery (SVD); 125 healthy term infants were monitored with pulseoxymeter after first ten minutes of life. Data were recorded from this monitoron a personal computer and analyzed by generalized estimating equations(GEE) method. Pulse rate was lower in babies born via SVD. Perfusionindex were higher in C/S group. Pleth variability index were higher in C/Sgroup. Higher pulse rate, PI and PVI values in babies born via C/S may beindicative of more significant hemodynamic changes in these infants duringearly transitional period after birth.
