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.

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.

In Reply.— We appreciate the interest and continuing contributions of Drs Pfenninger and Tschaeppeler. We agree with their assessment that the difference in mortality rates is probably attributable to selection differences. All five of their infants would have been excluded from our series, since proven sepsis and documented persistent pulmonary hypertension were both among the criteria for exclusion. As we noted in our article, the low mortality in our series was not surprising because of such exclusions.

Study the clinical profile of meconium aspiration syndrome (MAS) in neonates, in relation to birth weight, gestational age and their immediate outcome. Prospective observational cross sectional study. All preterm, term and post term infants, appropriate for gestational age with birth weight, delivered normally or by caesarean section or forceps, fulfilling all the inclusion criteria for MAS who were admitted to NICU, during the 9 months from January 2020 to September 2020 were included in the study. Over nine months' period, 574 neonates were admitted in NICU under that 312 neonates were in respiratory distress, out of which78 neonates were suffered with MAS. A detailed antenatal and natal history was elicited. Complications during delivery and details of resuscitation at birth, was done wherever required. Endo-tracheal intubation was done and bag and tube ventilation was given wherever needed. In MAS neonates, APGAR score at 1 minute and 5 minutes and gestational age was assessed with New Ballard’s score. A detailed clinical examination was carried out and respiratory distress was monitored by using Downes score system. Score > 6 was taken as an indication for assisted ventilation. 574 babies were admitted to NICU during the study period and out of them 312 were with respiratory distress. During the study period 78 (25%) babies had MAS. Conservative management was given to 59 cases (75.64%) and only 19 cases (24.36%) needed artificial ventilation, where indication was birth asphyxia, acute respiratory failure or other complications like pneumothorax. Out of 19 ventilated babies, 15 babies died and 4 babies survived and were discharged in good health. Conclusions: 1.Increased incidence of meconium aspiration syndrome was associated with increase in the gestational age (more in term and post term neonate, birth weight > 2.5kgs, 2. Highest mortality was associated with thick meconium and with low APGAR score at 5 minutes.

In Reply.— We agree with Dr Evans that bidirectional ductal shunting is more common than net right-to-left ductal shunting in premature neonates with severe RDS and persistent pulmonary hypertension. Our conclusion that large right-to-left shunts via the ductus are common findings in these cases was not intended to exclude the presence of concomitant left-to-right shunting. In our study population the incidence of right-to-left ductal shunting at 12 and 24 hours of age was 86% and 94% in premature neonates with fatal RDS, 39% and 34% in the severe RDS group, 4% and 0% in the no/mild RDS group, and 6% and 0% in the full-term neonates without RDS.

Respiratory distress in neonate defines as when rate of respiration is greater than sixty in one minute, nasal flaring, grunting and intercostal / sub coastal recession is present. Various causes are reported of respiratory distress in new born. Objectives: To determine frequency of respiratory distress in new born and to Find frequency of various etiologies of respiratory distress in full term newborn admitted up to the age of 24 hours of birth in Study Design: Cross sectional studies. Setting: Neonatal unit of Jinnah Hospital Lahore. Period: From February 10, 2016 till August 10, 2016. Material and Method: SPSS v-20 was used for analysis of data like name, age, sex, gestational age, maternal record of pregnancy and fetus for etiologies of respiratory distress. Results: There were 100(66.7%) male and 50(33.3%) females in this study. The mean gestational age of these newborn was 39.51±1.51 weeks. Respiratory distress was seen in 16(10.7%) of the cases. Transient tachypnea seen in 4(25%) of the cases, Meconium aspiration syndrome was diagnosed in 2(12.5%), Pneumothorax in 3(18.8%), Congenital pneumonia in 2 (12.5%), Sepsis in 6(37.5%) and Birth asphyxia 2 (12.5%) of early neonatal age were the common observed causes. Conclusion: Respiratory distress was 1/10 of the cases. The commonest etiologies were Sepsis preceding to Respiratory distress syndrome, MAS (Meconium Aspiration Syndrome), TTN (Transient Tacyhpnea of Newborn), Pneumothorax, Congenital pneumonia, Birth asphyxia.

Background: Meconium aspiration syndrome (MAS) is one of the common causes of neonatal respiratory distress. Overall frequency of meconium stained amniotic fluid (MSAF) ranges between 5 to 25%.Methods: Observational study was conducted on 96 newborns over a period of one year in the department of pediatrics, Himalayan Institute of Medical Sciences, Dehradun, Uttarakhand. All newborns, inborns and outborns with MSAF admitted in NICU of our hospital were taken.  Results: Out of 876 babies those had MSAF, 96 babies developed MAS with 10.95% incidence. Common maternal risk factors noted with MAS was maternal diabetes mellitus in 11 (15.71%) cases. Babies born via LSCS developed MAS in 51 (53.12%) and in babies delivered vaginally 45 (46.87%). MAS occurred mainly in term with mean gestational age of 38 weeks with SD of 1.85 weeks. The mean birth weight of newborns with MAS was 2794 g with 524 g SD. Most common complication was birth asphyxia in 36 (37.5%). Mortality occurred in 11 (11.4%). Mean gestational age and birth weight of mortality in MAS was 38 weeks with 2.5 weeks SD and 2800 g with 723 g SD respectively. Statistically significant association noted between mortality due to MAS and birth weight as p value<0.05, but no significant association noted between mortality and gestational age.Conclusions: MAS is a common cause of respiratory distress in newborns born through MSAF. With judicious use of available modes of ventilation and adjunctive therapies, infants with even the most severe MAS can usually be supported through the disease, with an acceptable burden of short-and long-term morbidity.

BACKGROUND: Preterm birth remains a major health issue worldwide. Preterm delivery affects over 7–12% of births in India and is responsible for up to 75% of neonatal deaths. Despite advances in medical technology, the prevalence of preterm birth is increasing. Discovery of antenatal corticosteroid for fetal maturation and its adoption into clinical practice highlights several fascinating and universal truths about science and medicine. The challenge in human studies is to demonstrate antenatal corticosteroid administration in pregnancy contributes to developmental programming and how this is manifested in later life. The World Health Organization recommends the use of one course of antenatal steroids for all pregnant women between 26 and 35 weeks of gestation who are at risk of preterm delivery within 7 days. Both, the American College of Obstetricians and Gynaecologists and the Royal College of Obstetricians and Gynaecologists recommend their use between 24 and 34 weeks of gestation (1). The use of antenatal steroids after 34 or 35 weeks of gestation is not recommended unless there is evidence of fetal pulmonary immaturity. Despite this, antenatal steroids are widely used globally across all gestational periods. In a diverse country like India, diversity in clinical practice is a reality. Hence, the present research study intends to study the maternal and perinatal outcomes with antenatal corticosteroid administration in preterm deliveries at Government district hospital, Nandyal in South India. AIMS AND OBJECTIVES Ÿ To determine the incidence of RDS at District hospital, Nandyal among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS and in those whose mothers did not receive ACS. Ÿ To determine the severity of RDS at District hospital, Nandyal among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS and in those whose mothers did not receive ACS. Ÿ To compare the neonatal mortality among neonates delivered between 28-37 weeks due to PTL, PPROM or severe PET whose mothers received ACS with those whose mothers did not receive ACS. Ÿ To determine the effectiveness of antenatal corticosteroid administration in preventing early neonatal respiratory distress syndrome in early preterm labour versus late preterm labour. Ÿ To determine the effectiveness of ACS administration in preventing neonatal complications with respect to the mode of delivery. METHODOLOGY: Study was conducted at Government District Hospital, Nandyal from 01/01/2019 to 30/10/2019. A structured questionnaire was prepared under guidance of thesis guide. All pregnant women with gestational age between 28 completed weeks to 37 completed weeks, presenting in OPD either in labour or getting admitted due to any other maternal medical complication, are initially assessed thoroughly to estimate the gestational age by history, LMP, early USG, and clinical examination. They are given a course of ACS if they were not expecting delivery within next 1 hour, after explaining the benets and risks of ACS as per recommendations of Federation of International st Gynecology and Obstetrics. Those who did not receive ACS or those who delivered within 24hrs of administration of 1 dose of ACS were considered as subjects in NACS group. Those who received ACS were considered as subjects in ACS group. After delivery, the neonate is followed up in NICU until discharged or until 7 days whichever is shorter. Mother is followed up for any clinical signs of infection, until she is discharged. Data is analyzed scientically. RESULTS: In Antenatal corticosteroids group (ACS), there were 36 subjects within 20 years, 43 subjects between 20-25 years, 29 subjects between 25-30 years, 25 subjects between 30-35 years. In No Antenatal corticosteroids group (NACS), there were 32 subjects within 20 years, 49 subjects between 20-25 years, 25 subjects between 25-30 years, 10 subjects between 30-35 years. Study observed that Antenatal corticosteroids group had lower incidence of Respiratory distress syndrome compared to No Antenatal corticosteroids group (12.07% versus 23.28%). Antenatal corticosteroids group had lower incidence of severe Respiratory distress syndrome compared to No Antenatal corticosteroids group (21.3 % versus 33.33%) among those who had Respiratory Distress Syndrome. Antenatal corticosteroids group had fewer admissions to NICU than No Antenatal corticosteroids group (20.69% versus 33.62%). Antenatal corticosteroids group had lower mortality than No Antenatal corticosteroids group (12.07 % versus 22.41%). Antenatal corticosteroids group had 35 % less chances of Respiratory distress syndrome compared to No Antenatal corticosteroids group. In No Antenatal corticosteroids group, subjects who underwent vaginal delivery had 10% less risk compared to those who underwent LSCS for their neonates to have Respiratory distress syndrome. In Antenatal corticosteroids group, subjects who underwent vaginal delivery had 14.29 % less risk compared to those who underwent LSCS for their neonates to have Respiratory distress syndrome. Antenatal corticosteroids group had maternal infection rate comparable to No Antenatal Corticosteroids group. CONCLUSION: Use of antenatal corticosteroids was found to be benecial in pregnant women with Gestational age of 28 completed weeks to less than 37 completed weeks at Government District hospital, Nandyal. Antenatal corticosteroids did not have statistically signicant adverse effects (i.e. increased rate of infection) in mothers.
