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.

ntroduction. The COVID-19 pandemic caused an outbreak of viral lung infections with severe acute respiratory syndrome complicated with acute respiratory failure. Despite the fact that the pandemic has a lengthened run, none of the therapeutic approaches have proved to be sufficiently effective according to the evidence-based criteria. We consider the use of surfactant therapy in patients with severe viral pneumonia and acute respiratory distress syndrome (ARDS) as one of the possible methods for treating COVID-19 related pneumonia. Objective. To prove the clinical efficacy and safety of orally inhaled Surfactant-BL, an authorized drug, in the combination therapy of COVID-19 related ARDS. Materials and methods. A total of 38 patients with COVID-19 related severe pneumonia and ARDS were enrolled in the study. Of these, 20 patients received the standard therapy in accordance with the temporary guidelines for the prevention, diagnosis and treatment of the novel coronavirus infection (COVID-19) of the Ministry of Health of the Russian Federation, version 9. And 18 patients received the surfactant therapy in addition to the standard therapy. Surfactant-BL was used in accordance with the instructions on how to administer the drug for the indication – prevention of the development of acute respiratory distress syndrome. A step-by-step approach to the build-up of the respiratory therapy aggressiveness was used to manage hypoxia. We used oxygen inhalation via a face mask with an oxygen inflow of 5–15 l/min, highflow oxygen therapy via nasal cannulas using Airvo 2 devices, non-invasive lung ventilation, invasive lung ventilation in accordance with the principles of protective mechanical ventilation. Results and discussion. Significant differences in the frequency of transfers to mechanical ventilation, mortality, Intensive Care Unit (ICU) and hospitalization length of stay (p <0.05) were found between the groups. Patients receiving surfactant therapy who required a transfer to mechanical ventilation accounted for 22% of cases, and the mortality rate was 16%. In the group of patients receiving standard therapy without surfactant inhalation 45% were transferred to mechanical ventilation, and 35% died. For patients receiving surfactant therapy, the hospital stay was reduced by 20% on average, and ICU stay by 30%. Conclusion. The inclusion of surfactant therapy in the treatment of COVID-19 related severe pneumonia and ARDS can reduce the progression of respiratory failure, avoid the use of mechanical ventilation, shorten the ICU and hospitalization length of stay, and improve the survival rate of this patient cohort.

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.

A study of 59 premature infants with respiratory distress syndrome has revealed the presence of severe increase in concentration of potassium with electrocardiographic changes. Thirty-six of 37 of these infants examined serially between 12 and 60 hours of age developed electrocardiographic abnormalities. Concentrations of potassium in serum of over 7.0 meq/l were associated with these prolonged conduction times. Concentrations of over 9.0 meq/l occurred in 12 infants, 11 of whom died. Parenteral administration of glucose, insulin, and bicarbonate produced a fall in the concentration of potassium in the serum and a correction of the electrocardiogram. Control premature and full-term infants had concentrations of potassium between 4 and 7 meq/l and never showed electrocardiographic disturbances. Evidence is produced that premature infants with the respiratory distress syndrome develop a toxic degree of hyperkalemia which is reversible.

OBJECTIVE: To determine the predictors of mortality following early rescue surfactant therapy in preterm babies with respiratory distress syndrome. STUDY DESIGN: Prospective cohort study enrolling babies between 28 weeks to 34 weeks with respiratory distress syndrome requiring early rescue surfactant therapy. For statistical analysis babies were further divided into two subgroups: survivors and non-survivors. Maternal and neonatal variables were compared between the two groups to find out the predictors of mortality. RESULTS: Out of total 110 babies, 72 (65.45%) survived. The mean birth weight and mean gestational age of the study population was 1614.36 (±487.86) g and 31.40 (±2.0)1 weeks, respectively. Birth weight <  1500 g, gestational age <  32 weeks, primiparity, vaginal delivery, prolonged rupture of membranes, lack of antenatal steroid cover, bag and mask ventilation at birth, sepsis, apneic episodes and mechanical ventilation were significantly associated with death on univariate analysis. On multivariate analysis, very low birth weight, vaginal delivery, lack of antenatal steroid cover, bag and mask ventilation at birth and mechanical ventilation were found to be independent predictors of mortality. CONCLUSIONS: Some of the identified predictors of mortality are modifiable and can be used to draw up a screening tool to predict the clinical severity and mortality among these babies.

Ventilatory support is vital for the management of severe forms of COVID-19. Non-invasive ventilation is often used in patients who do not meet criteria for intubation or when invasive ventilation is not available, especially in a pandemic when resources are limited. Despite non-invasive ventilation providing effective respiratory support for some forms of acute respiratory failure, data about its effectiveness in patients with viral-related pneumonia are inconclusive. Acute respiratory distress syndrome caused by severe acute respiratory syndrome-coronavirus 2 infection causes life-threatening respiratory failure, weakening the lung parenchyma and increasing the risk of barotrauma. Pulmonary barotrauma results from positive pressure ventilation leading to elevated transalveolar pressure, and in turn to alveolar rupture and leakage of air into the extra-alveolar tissue. This article reviews the literature regarding the use of non-invasive ventilation in patients with acute respiratory failure associated with COVID-19 and other epidemic or pandemic viral infections and the related risk of barotrauma.
