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.

Blood Flows

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.

The Third

In reporting the third case of Wilson-Mikity syndrome in a full-term neonate, Drs. Keidel and Feingold1 appear instead to have described a classic case of meconium aspiration syndrome. Their patient, delivered with difficulty at 41 weeks' gestation, aspirated meconium at the time of delivery and was severely asphyxiated at birth. Respiratory distress developed after resuscitation and the baby was noted to have "diffuse granularity of both lung fields and hyperinflation indicating meconium aspiration." Later, when the chest film showed "hyperexpanded lungs with depressed diaphragms and cyst-like foci alternating with coarse infiltrates" their diagnostic impression apparently changed to Mikity-Wilson syndrome.

The Relationship

To the Editor.— We read with interest Dr Gross' letter1 concerning the relationship between inborn and outborn infants with persistent pulmonary hypertension and the relevance of "classical" extracorporeal membrane oxygenation (ECMO) inclusion criteria and outcome of therapy. We wholly agree with his observation that early skilled respiratory treatment of infants with persistent pulmonary hypertension to a large extent can obviate the need for ECMO, and we wish to report our experience. As has been noted, the major category of patients requiring ECMO are those with severe meconium aspiration syndrome.2

Persistent pulmonary hypertension of the newborn (PPHN) is an essential cause for hypoxic respiratory failure with significant morbidity and mortality in term and near-term neonates. Hydrocortisone has been shown to decrease oxygen dependency and pulmonary hypertension in neonates with meconium aspiration syndrome and animal studies, respectively. We hypothesize that hydrocortisone will improve oxygenation in term and near-term infants with pulmonary hypertension. We performed a retrospective chart review of all infant with PPHN who received intravenous hydrocortisone therapy as a rescue for severe PPHN. Clinical response was objectively measured using, oxygenation index (OI), PaO2/FiO2 ratio, and inotrope score before, during, and after the hydrocortisone course. We found that hydrocortisone administration resulted in significant improvement of systolic blood pressure, OI, and PaO2/FiO2. In conclusion, hydrocortisone increased systolic blood pressure and improved oxygenation in term and near-term infants with persistent pulmonary hypertension. Prospective randomized trials are required to evaluate these findings further.

Background & Objective: Persistent pulmonary hypertension of the newborn (PPHN) is described as severe respiratory failure along with hypoxaemia. PPHN is known to be linked with high morbidity and mortality around the world. This study was planned to determine the postnatal causes and assess the severity of persistent pulmonary hypertension of newborn in babies presenting to the Children’s Hospital, Multan. Methods: This observational study was conducted at the Department of Paediatric Cardiology, The Children Hospital &Institute of Child Health, Multan, Pakistan from July to December 2019. A total of 122 confirmed cases of PPHN admitted having gestational age above 34 weeks were enrolled. Demographic data of the newborns was recorded along with maternal medical history, pregnancy status and postnatal causes of PPHN. Severity of PPHN was also recorded. Results: Out of a total of 122 cases of PPHN, 81 (66.3%) were male. Majority, 78 (64.0%) had gestational age above 37 weeks. Mode of delivery as cesarean section was noted in 70 (57.4%). Meconium aspiration syndrome 52 (42.6%), birth asphyxia 48 (39.3%), respiratory distress syndrome 23 (18.8%) and sepsis 33 (27.0%) were found to be the commonest causes of PPHN. Severe PPHN was found to be the most frequent, noted among 63 (51.6%) while Moderate PPHN was observed in 40 (32.8%) and Mild PPHN in 19 (15.6%). Morality was noted among 26 (21.3%) of cases. Conclusion: Meconium aspiration syndrome, birth asphyxia and respiratory distress syndrome were the commonest postnatal causes of PPHN. Severe PPHN was found to be the most frequent form of PPHN. doi: https://doi.org/10.12669/pjms.37.5.2218 How to cite this:Arshad MS, Adnan M, Anwar-ul-Haq HM, Zulqarnain A.
