“…Pathophysiology of interstitial emphysema as a central issue of air leak syndrome, and therefore pneumothorax, is very complex and still unclear. As already known, the risk factors for development of pneumothorax and all other phenomena from air leak syndrome, include prematurity, low Apgar score, respiratory distress syndrome and infection (neonatal sepsis, pneumonia), as well as some settings of mechanical ventilation (22, 23). In our study the most commonly associated diseases in neonates with pneumothorax were respiratory distress syndrome, pneumonia and sepsis, but there was no significant difference in the values of inflammatory markers in neonates with pneumothorax compared to others.…”

“…Crucial for a satisfactory outcome of the NP is timely recognition (there is no doubt about it in literature), and adequate treatment (there is still some difference). Commonly, conservative (expectant) approach is applied for small and asymptomatic NP, while complete NP requires surgical approach, needle aspiration or thoracic drainage (22, 23). Only one case of neonatal pneumothorax in our study, was treated conservatively, while the other 21 cases required urgent thoracic drainage.…”

Aim: The aim of this study was to analyze risk factors and outcome of neonatal pneumothorax in Tuzla Canton. Methods: Neonates with chest X-ray confirmed pneumothorax in University Clinical Center of Tuzla, within a three-year period, from January 2015 to December 2017, were retrospectively studied. Participants were evaluated for baseline characteristics, predisposing factors of neonatal pneumothorax, accompanying disorders and mortality. Results: During the observed three-year period 11425 neonates were born in Tuzla Canton, with 7.33 % of preterm births, and 604 neonates were treated in NICU, with 265 neonates who required mechanical ventilation. Neonatal pneumothorax (NP) was diagnosed in 22 patients (9 term, 13 preterm), 12 (54.5%) were male. The incidence was 0.20% of total births, respectively 3.64% of those treated in NICU. The mean gestational age were 35.1 ± 3.0 weeks and birth weight 2 506.8 ± 727.7 grams. NP was mostly unilateral (72.7%) and right-sided. The most commonly associated diseases were: respiratory distress syndrome, intracranial haemorrhage, pneumonia, transient tachypnea and sepsis. In 8 (36.4%) neonates, the underlying cause of NP could be mechanical ventilation (secondary), whereas in 14 (63.6%) NP was spontaneous, without previous mechanical ventilation, although 11 of them required mechanical ventilation after pneumothorax. Conclusion: All perinatal risk factors were investigate, and significant differences in two observed groups related to mechanical ventilation were found for birth weight, gestational age, Caesarean section, length of mechanical ventilation, surfactant replacement therapy and outcome. Three (13.64%) neonates with NP died, and among risk factors with poor outcome, significant was only Apgar score in the first minute ≤ 5.

“…A pneumothorax must be considered in mechanically ventilated infants who develop unexplained alterations in hemodynamics, pulmonary compliance or oxygenation and ventilation [3] Pneumothorax in an infant can be virtually asymptomatic or may be associated with severe circulatory disturbances including hypotension and hypoperfusion [4]. The risk factors for development of pneumothorax include prematurity, low Apgar score, respiratory distress syndrome and infection (neonatal sepsis, pneumonia), as well as some settings of mechanical ventilation [5].…”

Background: Pneumothorax (PTX) is a common complication and potentially life threatening condition for neonates in the neonatal intensive care unit (NICU). The use of ventilatory support and neonatal resuscitation procedures with positive pressure is deemed necessary. Aim of work: The aim of this study is to identify the risk factors which predispose or relate to pneumothorax in neonates admitted in NICU of AL-Azhar Assuit University Hospital and the outcome of this problem. Patients and Methods: This is a retrospective descriptive study was carried out on mechanically ventilated neonates admitted to NICU of AL-Azhar Assuit University Hospital during the period from 1 st January 2018 to 1 st January 2020. Results: On studying the demographic and clinical characteristics of cases and risk factors implicated in incidence of pneumothorax, it's reported that 41.7% of cases were males, 75% born by caesarean section, most of cases with gestational age < 34 weeks, with birth weight < 2 kilogram.Respiratory distress syndrome (RDS) was the most prevalent underlying lung disease, as 75% of pneumothorax patients were having RDS, probably being the most common cause of admission and need for ventilatory support. During admission, 4 patients died with mortality rate 33.3% of all patients presenting with pneumothorax. Conclusion: The incidence of PTX was high due to positive pressure ventilation. It was higher in neonates on synchronized intermittent mechanical ventilation (SIMV) than on continuous positive airway pressure (CPAP) in preterm infants, in those of elective CS and neonates with low birth weight. Respiratory distress syndrome was the most prevalent underlying lung disease.Mortality was high due to lower birth weight and gestational age, the need of these patients to mechanical ventilation and more severe chest condition than other patients. Recommendation:Intensive care for neonates who develop pneumothorax is necessary as they have higher mortality rates.
