Neonatal resuscitation (NRP) guidelines suggest targeting 85–95% preductal SpO2 by 10 min after birth. Optimal oxygen saturation (SpO2) targets during resuscitation and in the post-resuscitation management of neonatal meconium aspiration syndrome (MAS) with persistent pulmonary hypertension (PPHN) remains uncertain. Our objective was to compare the time to reversal of ductal flow from fetal pattern (right-to-left), to left-to-right, and to evaluate pulmonary (QPA), carotid (QCA)and ductal (QDA) blood flows between standard (85–94%) and high (95–99%) SpO2 targets during and after resuscitation. Twelve lambs asphyxiated by endotracheal meconium instillation and cord occlusion to induce MAS and PPHN were resuscitated per NRP guidelines and were randomized to either standard (85–94%) or high (95–99%) SpO2 targets. Out of twelve lambs with MAS and PPHN, six each were randomized to standard and high SpO2 targets. Median [interquartile range] time to change in direction of blood flow across the ductus arteriosus from right-to-left, to left-to-right was significantly shorter with high SpO2 target (7.4 (4.4–10.8) min) compared to standard SpO2 target (31.5 (21–66.2) min, p = 0.03). QPA was significantly higher during the first 10 min after birth with higher SpO2 target. At 60 min after birth, the QPA, QCA and QDA were not different between the groups. To conclude, targeting SpO2 of 95–99% during and after resuscitation may hasten reversal of ductal flow in lambs with MAS and PPHN and transiently increase QPA but no differences were observed at 60 min. Clinical studies comparing low and high SpO2 targets assessing hemodynamics and neurodevelopmental outcomes are warranted.

Meconium Aspiration

Objective. In light of the paucity of published data on the use of surfactant in full-term infants with respiratory failure due to meconium aspiration syndrome and respiratory distress syndrome, we report our experience with this therapy. Our goal was to explore possible justification for randomized controlled trials of surfactant treatment in similar patients at an earlier, less severe stage of the disease. Methods. Retrospective consecutive case series of 20 infants with severe meconium aspiration syndrome and 29 infants with severe respiratory distress syndrome who received bovine surfactant between March 1990 and December 1992 in three neonatal intensive care units in a regionalized setting. Outcome of treatment was assessed by comparing changes in several respiratory indices including the oxygenation index, between 4 and 6 hours and 1 and 3 hours before and after the first dose of surfactant. Differences were analyzed using analysis of variance for repeated measures, with treatment and time as co-variates. Results. In the meconium aspiration group the mean oxygenation index decreased from 36 ± 12 at 1 to 3 hours presurfactant to 24 ± 14 at 1 to 3 hours postsurfactant (P < .001). In the patients with respiratory distress syndrome the mean oxygenation index fell from 30 ± 17 at 1 to 3 hours presurfactant to 12 ± 6 at 1 to 3 hours postsurfactant (P = .0001). Three of 20 patients with meconium aspiration syndrome and 3 of 29 patients with respiratory distress syndrome received extracorporeal membrane oxygenation. Conclusions. Surfactant therapy in full-term infants with respiratory failure due to the meconium aspiration and respiratory distress syndromes is often effective in improving gas exchange. A randomized controlled trial of surfactant therapy at an earlier stage in the course of the illness should be performed.

BACKGROUND: Occurance of meconium-stained amniotic uid (MSAF) during labour may be considered as a measure for prediction of poor fetal outcomes such as meconium aspiration syndrome and perinatal asphyxia ,resulting in perinatal as well as neonatal morbidity and mortality. It constitutes about 5% of deliveries with meconium stained amniotic uid and death results in about 12% of infants with MAS. METHODS: 40 cases of meconium stained liquor detected after spontaneous or artical rupture of membranes taken during labour from june 2020 to december 2020 and their outcome in terms of mode of delivery(whether vaginal delivery or lower segment caesarean section) and fetal outcome and associated maternal high risk were studied RESULT: Anemia was co existant in around 15%, pregnancy induced hypertension(PIH) in 25%and premature rupture of membrane in 10%.Pregnancies complicated with Pregnancy induced hypertension had signicant higher rate of meconium stained liquor among all cases. Caesarean Section was commonly performed in meconium stained amniotic uid cases and accounted for about 65%of all cases. CONCLUSIONS: Meconium Stained amniotic uid increases the chances of caesarean rates,leading to birth asphyxia ,Meconium Aspiration Syndrome and hence increases the chances of neonatal intensive unit admission.
