Saturimetry

Background: Saturimetry is another fetal wellness monitoring technique, ft measure oxygen saturation of the fetal district bk arterioles (Sp02). Fetal wellness monitoring through Saturimetry was applied in 20 cases. Methods: During the labour of all the 20 cases we found particular conditions that lead us to define not reassuring CTG plots: heart rate with low variability and/or fetal heart rate decelerations. When we experienced these CTG signs we positioned the saturimeter. There were verified the saturimeter positioning conditions in all 20 cases: 2cm dilatation; Positioning with an it sac or with ruptured membranes; Positioning on any fetal surface. Results: 18 out of 20 patients had spontaneous delivery: even tough not that reassuring CTG persistent signs, we found good of Sp02 (> 30%). These allowed to continue the labour until the natural delivery. 2 out of 20 patients had cesarean section. All neonates had good birth conditions with a good Apgar score. In the first of the 2 cesarean section, after fetal heart rate deceh onset, we positioned the saturimeter. Even tough we experienced good fetal saturation values (>30%, 50-60% average) that was reassuring, a cesarean section was performed as fetal heart rate deceleration were observed in the CTG plot and non-progress uterine cervix dilatation. Conditions of the neonate at birth were good: no suffering signs, Apgar score of 9 at the 1st minute a at the 5th minute. Second case was referred to a labouring patient whose CTG monitoring evidenced low fetal heart rate variable. We positioned the saturimeter. Cesarean section was resolved since persistence of cardiotocographic signs we previously desct and the appearance of dynamic dystocia. Conclusions: Saturimetry surveyed during alt the monitoring evidenced fetal wellness indicating data. The use of saturimetry avoid cesarean section rate as well as litigation for error in decision making.
