Risk Factors for Preoperative Pneumothorax in Neonates With Isolated Left-Sided Congenital Diaphragmatic Hernia: An International Cohort Study. J Pediatr Surg 2024; 59:1451-1457. [PMID: 38388286 DOI: 10.1016/j.jpedsurg.2024.01.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 12/30/2023] [Accepted: 01/19/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND We aimed to investigate the clinical characteristics and outcomes of patients with isolated left-sided congenital diaphragmatic hernia (CDH) who developed preoperative pneumothorax and determine its risk factors. METHODS We performed an international cohort study of patients with CDH enrolled in the Congenital Diaphragmatic Hernia Study Group registry between January 2015 and December 2020. The main outcomes assessed included survival to hospital discharge and preoperative pneumothorax development. The cumulative incidence of pneumothorax was estimated by the Gray test. The Fine and Gray competing risk regression model was used to identify the risk factors for pneumothorax. RESULTS Data for 2858 neonates with isolated left-sided CDH were extracted; 224 (7.8%) developed preoperative pneumothorax. Among patients with a large diaphragmatic defect, those with pneumothorax had a significantly lower rate of survival to discharge than did those without. The competing risks model demonstrated that a patent ductus arteriosus with a right-to-left shunt flow after birth (hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.21-2.63; p = 0.003) and large defects (HR: 1.65; 95% CI: 1.13-2.42; p = 0.01) were associated with an increased risk of preoperative pneumothorax. Significant differences were observed in the cumulative incidence of pneumothorax depending on defect size and shunt direction (p < 0.001). CONCLUSIONS Pneumothorax is a significant preoperative complication associated with increased mortality in neonates with CDH, particularly in cases with large defects. Large diaphragmatic defects and persistent pulmonary hypertension were found to be risk factors for preoperative pneumothorax development. LEVEL OF EVIDENCE LEVEL Ⅲ Retrospective Comparative Study.

Tamai K, Takeuchi A, Nakamura M, Nakamura K, Matsumoto N, Yorifuji T, Kageyama M. Association between mean airway pressure during high-frequency oscillatory ventilation and pulmonary air leak in extremely preterm infants during the first week of life. Front Pediatr 2024; 12:1410627. [PMID: 38873580 PMCID: PMC11171124 DOI: 10.3389/fped.2024.1410627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 05/21/2024] [Indexed: 06/15/2024] Open
Abstract
Background While positive pressure ventilation has been considered an important contributing factor associated with pulmonary air leaks, studies examining the association between specific ventilatory settings during acute-phase high-frequency oscillatory ventilation (HFOV) and pulmonary air leaks among extremely preterm infants are limited. Methods This was a single-center retrospective cohort study conducted at an institution that primarily used HFOV after intubation in extremely preterm infants. We analyzed data from extremely preterm infants born between 2010 and 2021. The primary outcome was pulmonary air leakage during the first 7 days of life. The exposure variable was the maximum mean airway pressure (MAP) on HFOV during the first 7 days of life or before the onset of pulmonary air leaks. Maximum MAP was categorized into three groups: low (7-10 cmH2O), moderate (11-12 cmH2O), and high (13-15 cmH2O) MAP categories. We conducted robust Poisson regression analyses after adjustment for perinatal confounders, using the low MAP category as the reference. Results The cohort included 171 infants (low MAP, 123; moderate MAP, 27; and high MAP, 21). The median (interquartile range) gestational age and birth weight were 25.7 (24.3-26.7), 25.7 (24.9-26.9), and 25.3 (24.3-26.6) weeks and 760 (612-878), 756 (648-962), and 734 (578-922) g for infants in the low, moderate, and high MAP categories, respectively. Compared to infants in the low MAP category, those in the high MAP category had a higher incidence of pulmonary air leaks (4.1% vs. 33.3%; adjusted risk ratio, 5.4; 95% confidence interval, 1.6-18.5). In contrast, there was no clear difference in the risk of pulmonary air leaks between the moderate and low MAP categories (3.7% vs. 4.1%; adjusted risk ratio, 0.9; 95% confidence interval, 0.1-6.1). Conclusion Extremely preterm infants requiring high MAP (≥13 cmH2O) in acute-phase HFOV had a higher risk of pulmonary air leak during the first 7 days of life.

Abstract
With the advent of surfactant and gentle ventilation, the incidence of neonatal pneumothorax has decreased over the last two decades. Pneumothorax associated with respiratory distress syndrome is more common in preterm infants, but term infants often present with isolated pneumothorax. The use of CPAP or non-invasive respiratory support in the delivery room for a term infant with respiratory distress increases transpulmonary pressures and increases the risk of pneumothorax. Prompt diagnosis with a high index of suspicion, quick evaluation by transillumination, chest X-ray or lung ultrasound is critical. Management includes observation, needle thoracocentesis and if necessary, chest tube placement. This manuscript reviews the incidence, pathogenesis, diagnosis and management of a term infant with isolated pneumothorax, summarizing the combination of established knowledge with new understanding, including data on diagnostic modes such as ultrasound, reviewing preventative measures, and therapeutic interventions such as needle thoracocentesis and a comparison of pigtail vs. straight chest tubes.

Abstract
Background: Respiratory distress syndrome (RDS) is a common critical lung disease in newborn infants, especially those in premature infants with higher mortality rate. Early and correct diagnosis is the key to improve its prognosis. Previously, the diagnosis of RDS mainly relied on chest X-ray (CXR) findings, and it has been graded into four stages based on the progression and severity of CXR changes. This traditional diagnosing and grading method may lead to high misdiagnosis rate or delayed diagnosis. Recently, using ultrasound to diagnose neonatal lung diseases and RDS is becoming increasingly popular, and the technology is gaining higher sensitivity and higher specificity. The management of RDS under lung ultrasound (LUS) monitoring has achieved significant results, reducing the misdiagnosis rate of RDS, thereby reducing the probability of mechanical ventilation and the use of exogenous pulmonary surfactant, and making the success rate of treatment of RDS up to 100%.Objective: The purpose of the article was to introduce the ultrasound grading methods and criteria of RDS, in order to promote the application of LUS in the diagnosis and treatment of RDS.Methods: Literature (in English and Chinese) on the use of ultrasound in the diagnosis of neonatal RDS between 2008 and 2022 was selected for inclusion in this study.Results: From the collected literature, the use of ultrasound in the diagnosis of RDS is increasing, and people's understanding of the ultrasound imaging findings of RDS is also changing. Among them, the research on ultrasound grading of RDS is the latest progress.Conclusion: Ultrasound is accurate and reliable in the diagnosis and differential diagnosis of RDS. It is of great clinical value to master the ultrasound diagnosis and grading criteria of RDS.

Abstract
BACKGROUND Neonatal pneumothorax (NP) in neonates is a medical emergency with a significant incidence of morbidity and mortality. There is a paucity of national and regional data about the epidemiological and clinical profiles of pneumothorax. AIM The study aim is to identify the demographics, predisposing factors, clinical profiles, and outcomes of NP in a tertiary neonatal care center in Saudi Arabia. METHODS A retrospective study of all newborns admitted at the neonatal intensive care unit at International Medical Centre, Jeddah, Saudi Arabia, over seven years period between January 2014 and December 2020 was reviewed. A total of 3,629 newborns admitted to the neonatal intensive care unit were included in the study. Data collected included baseline characteristics, predisposing factors, associated morbidities, management, and outcomes of NP. Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 26 (IBM Corp., Armonk, NY). RESULTS Of a total of 3,692 included neonates, pneumothorax was detected in 32 neonates with an incidence of 1.02% (ranging from 0.69% to 2%), and 53.1% were males. The mean gestational age was 32 weeks. Our study found that most infants with pneumothorax were extremely low birth weight (ELBW) in 19 babies (59%). The most common predisposing factors were respiratory distress syndrome in 31 babies (96.9%) followed by the need for bag-mask ventilation in 26 babies (81.3%). Twelve newborns (37.5%) with pneumothorax died. Following an analysis of all risk variables, the one-minute Apgar score <5, associated intraventricular hemorrhage, and respiratory support need were shown to be significantly linked with death. CONCLUSION Pneumothorax is not an uncommon neonatal emergency event, especially for ELBW infants, infants requiring respiratory support, or infants with underlying lung disease. Our study describes the clinical profile and affirms the significant burden of NP.

Abstract
BACKGROUND Management of pneumothorax in neonates requiring retrieval poses unique challenges, including decision to insert an intercostal catheter (ICC). We aimed to report the proportion and characteristics of neonates transported with and without ICC insertion and the incidence of deterioration in neonates transported with pneumothorax. METHODS A retrospective cohort study of neonates transported with pneumothorax between 2016 and 2020 in Victoria, Australia. Univariate analysis was performed on patient and clinical characteristics, followed by multivariate analysis to identify risks independently associated with ICC insertion. RESULTS 174 neonates were included. Mean (SD) gestational age (GA) was 37.5 (2.8) weeks. Eighty-two neonates (47%) had ICC inserted. On multivariate analysis, risk factors independently associated with ICC insertion were mechanical ventilation (MV) preceding retrieval team arrival (OR 12, 95% CI 3.1 to 46.6, p<0.001) and radiographical mediastinal shift (MS) (OR 6.2, 95% CI 2.4 to 16.2, p<0.001). Increasing GA is negatively associated with ICC insertion (OR 0.66, 95% CI 0.5 to 0.8, p<0.001). No significant difference in incidence of deterioration between the ICC group and the no-ICC group was observed (8.5% vs 5.4%, p=0.55). Ninety-five neonates were treated with needle aspiration (NA); 40 (42%) subsequently avoided ICC insertion. Twelve (13%) neonates transported without ICC had insertion within 24 hours following transport. CONCLUSION Many neonates with pneumothorax are transported without ICC, with low incidence of deterioration and ICC insertion within 24 hours after transport. More than a third of neonates managed with NA avoided ICC insertion. The likelihood of ICC insertion is increased by lower GA, MV prior to retrieval team arrival and radiographical MS.

Abstract
INTRODUCTION Pneumothorax in neonates can be life-threatening. In neonates without respiratory distress, spontaneous pneumothorax can also develop under certain conditions. OBJECTIVES To determine the incidence of ultrasonographic signs of pneumothorax in asymptomatic neonates using lung ultrasound as the diagnostic tool. METHODS This was an observational prospective study conducted at the Basurto University Hospital (Bilbao, Spain) between January 2018 and December 2020. Lung ultrasound was performed during routine examination of asymptomatic neonates admitted to the maternity ward. RESULTS Of a total of 204 asymptomatic neonates included in the study, 21 (10.3%) presented ultrasound signs of pneumothorax (Group A), and 183 (89.7%) had a normal lung ultrasound (Group B). Lung ultrasound was performed after a mean of 19 h of life (range 9-34). The presence of A-lines behind the sternum in the anterior transverse plane, at the intermammillary level, was observed in 100% of patients in Group A compared to no cases in Group B (p < 0.0001). The neonates of Group A presented the lung point located in the midclavicular line, indicative of a mild air leak. CONCLUSIONS Lung ultrasound allows precise detection of suspected small-sized air leaks that can be detected in asymptomatic neonates. The true incidence of pneumothorax in asymptomatic neonates may be substantially higher than previously described in the literature.

Abstract
BACKGROUND Air leaks, especially pulmonary interstitial emphysema (PIE), are increasingly uncommon respiratory complications of the newborn. Despite PIE having a decreasing incidence, it continues to have a high morbidity and mortality rate. This makes PIE one of the most severe respiratory complications to affect a newborn. Air leaks occur when there is overdistension of the terminal airways or alveoli, which results in air dissecting into extra-alveolar spaces. Recognizing the signs of air leaks is paramount to allow for appropriate diagnosis and treatment of the newborn to improve morbidity and mortality. Treatment modalities range from positioning the newborn in the decubitus position to surgical intervention. PURPOSE To summarize current evidence on the pathophysiology, risk factors, diagnosis, treatment, and management of PIE and pneumothorax. DATA SOURCES Two databases were systematically reviewed with key words later. Articles in English with date restrictions from 2016 to current were included. STUDY SELECTION Inclusion criteria of randomized controlled trials, case studies/reports, and review articles were utilized. Twenty articles, primarily case reports and studies, were reviewed. DATA EXTRACTION Guidelines for data abstraction were followed via independent extraction by a single observer. RESULTS Qualitative results were utilized to formulate current treatment of air leaks. IMPLICATIONS FOR PRACTICE This article provides guidance for frontline neonatal providers on current treatment and management of air leaks in the newborn population.

Abstract
Perioperative neonatal pneumothorax (NP) is rare but very fatal. Most of the surgeries and treatments in the neonatal period are time-limited or emergent, and there are often some risk factors for pneumothorax before surgery. Physicians, surgeons and anesthesiologists need to identify possible risk factors for pneumothorax before surgery in preterm babies, patients receiving mechanical ventilation and those with underlying lung disease. The clinical presentation of NP is nonspecific, and patients may rapidly develop life-threatening complications if not promptly diagnosed and managed. This review highlights recent progress in the identification of risk factors, clinical manifestations, diagnosis and management of NP during the perioperative period.

Abstract
BACKGROUND Tension pneumothorax of the contralateral lung during single-lung ventilation (SLV) combined with artificial pneumothorax can cause cardiac arrest due to bilateral pneumothorax. If not rapidly diagnosed and managed, this condition can lead to sudden death. We describe the emergency handling procedures and rapid diagnostic methods for this critical emergency situation.
CASE SUMMARY We report a case of bilateral pneumothorax in a neonatal patient who underwent thoracoscopic esophageal atresia and tracheoesophageal fistula repair under the combined application of SLV and artificial pneumothorax. The patient suffered sudden cardiac arrest and received emergency treatment to revive her. The recognition of dangerous vital sign parameters, rapid evacuation of the artificial pneumothorax, and initiation of lateral position cardiopulmonary resuscitation while simultaneously removing the endotracheal tube to the main airway are critically important. Moreover, even though the sinus rhythm was restored, the patient’s continued tachycardia, reduced pulse pressure, and depressed pulse oximeter waveform were worrisome. We should highly suspect the possibility of pneumothorax and use rapid diagnostic methods to make judgment calls. Sometimes thoracoscopy can be used for rapid examination; if the mediastinum is observed to be shifted to the right, it may indicate tension pneumothorax. This condition can be immediately relieved by needle thoracentesis, ultimately allowing the safe completion of the surgical procedure.
CONCLUSION Bilateral pneumothorax during SLV combined with artificial pneumothorax is rare but can occur at any time in neonatal thoracoscopic surgery. Therefore, anesthesiologists should consider this possibility, be alert, and address this rare but critical complication in a timely manner.

Abstract
Background and Objectives: Pneumothorax implies the presence of air in the pleural space between the visceral and parietal pleura. The aim of this study was to investigate the incidence, clinical characteristics, risk factors, therapy and perinatal outcome in neonates with pneumothorax in a tertiary care center. Materials and Methods: A retrospective study based on a five-year data sample of neonates with pneumothorax was conducted in a Maternity Hospital with a tertiary NICU from 2015 to 2020. We included all neonates with pneumothorax born in our hospital and compared demographic characteristics, perinatal risk factors, anthropometric parameters, comorbidities, clinical course and method of chest drainage between term (≥37 GW) and preterm (<37 GW) neonates. Results: The study included 74 newborns with pneumothorax, of which 67.6% were male and 32.5% were female. The majority of women (59.5%) had no complications during pregnancy. Delivery was mainly performed via CS (68.9%). Delivery occurred on average in 34.62 ± 4.03 GW. Significantly more (p = 0.001) children with pneumothorax were born prematurely (n = 53; 71.6%) than at term (n = 21; 28.4%). Most of the neonates had to be treated with ATD (63.5%) and nCPAP (39.2%), but less often they were treated with surfactant (40.5%) and corticosteroids (35.1%). O2 therapy lasted an average of 8.89 ± 4.57 days. Significantly more (p = 0.001) neonates with pneumothorax had additional complications, pneumonia, sepsis, convulsions and intraventricular hemorrhage (68.9%). However, most children had a good outcome (83.8%) and were discharged from the clinic. Fatal outcomes occurred in six cases, while another six neonates had to be transferred to referral neonatal centers for further treatment and care. Conclusion: Significantly more children with pneumothorax were born prematurely than at term. With adequate therapy, even premature newborns can successfully recover from pneumothorax.

Abstract
Purpose: To evaluate the incidence rate, clinical characteristics, and perinatal outcomes of pneumothorax in late preterm and full-term newborns with respiratory distress and analyze the risk factors associated with pneumothorax.Methods: Infants born at ≥34 weeks’ gestation with respiratory distress and pneumothorax admitted between February 2014 and December 2020 were enrolled in this study. The pneumothorax group (n=36) was matched to the control group (n=144) in a 1:4 ratio, based on gestational age and birth weight. Risk factors were identified using logistic regression analysis with backward stepwise selection.Results: The incidence of pneumothorax during the study period was 1.36% (38/2,788). All patients were diagnosed with pneumothorax within 48 hours after birth, and increased oxygen demand was the most common symptom. The proportion of mortality and perinatal morbidity, such as intraventricular hemorrhage ≥grade 3, was significantly higher in the pneumothorax group than in the control group. The risk factors associated with pneumothorax were the need for positive pressure ventilation in the delivery room (odds ratio [OR], 3.40; 95% confidence interval [CI], 1.26 to 9.12; P=0.015) and a higher fraction of inspired oxygen to achieve an oxygen saturation of ≥90% on admission (OR, 1.06; 95% CI, 1.03 to 1.09; P<0.001).Conclusion: Pneumothorax should be suspected in late preterm and full-term newborns with respiratory distress within the first 3 days of life. Based on these risk factors, early diagnosis can reduce perinatal mortality and morbidity.

Abstract
BACKGROUND Respiratory distress syndrome (RDS) is a common disease that seriously endangers the life and safety of newborns, especially premature infants. Exogenous pulmonary surfactant (PS) is the specific agent for the treatment of neonatal RDS. Lung ultrasound (LUS) has been successfully used in the diagnosis of RDS, but its value in guiding the application of PS is still unclear. This paper explored whether the application of PS under LUS monitoring has some advantages, including (1) decreasing the misdiagnosis rate of RDS and decreasing probability of using PS, and (2) reducing the dose of PS without reducing the therapeutic effect. METHODS This study included two parts. Part 1: To decide whether the LUS is good to differentiate RDS from other lung diseases in the premature infants. All patients who were diagnosed with RDS and required PS treatment based on conventional criteria were routinely examined by LUS. Then, according to LUS findings, we decided whether they needed to receive PS treatment. Part 2: To see the dose reduction of surfactant is applicable. In RDS patients diagnosed based on LUS presentation and treated with Curosurf (Chiesi Pharmaceutical, Parma, Italy), the dose of Curosurf was compared with that recommended by the European RDS management guidelines. RESULTS (1) Since March 2017, 385 newborn infants admitted to our neonatal intensive care unit met the traditional diagnostic criteria of RDS. Of these, only 269 cases were diagnosed with RDS and needed PS treatment according to LUS manifestations. The other 116 infants who did not meet the criteria for ultrasound diagnosis of RDS did not receive PS supplementation but obtained good outcomes, that is LUS findings decreased a misdiagnosis rate of RDS by 30.1% and subsequently resulted in a 30.1% reduction in PS use. (2) Among the 269 RDS patients diagnosed based on LUS findings, 148 were treated with Curosurf (another 121 RDS infants who received domestic PS treatment were not included in the study group), and the average dose was 105.4 ± 24.3 mg/kg per time, which is significantly lower than the dose of 200 mg/kg per time recommended by the European RDS guidelines. (3) The mortality rate of RDS patients was 0%, and no patients had ventilator-associated pneumonia or bronchopulmonary dysplasia in this study. CONCLUSION LUS can decrease the misdiagnosis rate of RDS, thereby decreasing the probability of using PS and decreasing the dose of PS, and can help RDS infants to achieve better outcomes.

Abstract
BACKGROUND Inserting a chest drain for a left-sided neonatal pneumothorax carries a risk of penetrating the pericardium. We identified reference ranges for the chest wall thickness (CWT) and distance between the pericardium and parietal pleura to improve safety of chest tube insertion. METHOD We prospectively measured the CWT using ultrasound in 20 neonates (body weight [BW] 640-2,700 g, age <10 days) at the usual site of puncture in the 4th and 5th intercostal space (ICS). Furthermore, we measured the minimal distance between the parietal pleura and the cardiac silhouette in 131 neonatal chest X-rays (birth weight, 420-4,930 g [divided into 11 weight groups]; age <10 days). Both data sets were transformed into weight-dependent percentiles (Ps). We considered the difference between the sum of P 2.5 for the CWT plus P 2.5 for pleura-heart distance minus P 97.5 for the CWT as a safe corridor for placing the tip of the needle. RESULTS At both ICSs, curves for the above metrics did not cross, indicating a narrow but safe corridor for each BW with at least 97.5% probability. This safety corridor was 4.6-5.2 mm wide for the 4th and 2.8-3.4 mm for the 5th ICS. CONCLUSION These data offer a reference for left-sided chest drain insertion for BW <2,700 g, which may help to improve safety of the procedure.

Abstract
AIM The primary objective was to describe the incidence, symptoms, clinical signs, and time of onset of neonatal pneumothorax in Örebro County during 2011-2017. Secondary objectives were to describe risk factors, diagnostic procedures, treatments, and mortality and to compare preterm with term/post-term neonates. MATERIALS AND METHODS This retrospective population-based descriptive study included all neonates born in Örebro County during 2011-2017 and admitted to the neonatal intensive care unit at Örebro University Hospital at age <28 days with an x-ray verified diagnosis of "Pneumothorax originating in the perinatal period" in their medical record. RESULTS Seventy-five neonates matched the inclusion criteria. The incidence of neonatal pneumothorax in Örebro County during the study period was 3.1 (95% CI: 2.5-3.8) per 1000 live births. All neonates were <48 h at debut of respiratory symptoms and the most common symptom was tachypnea. Twelve (16%) received invasive treatment. The mortality rate was 2 (3%), none due to pneumothorax. CONCLUSION The incidence of 3.1 per 1000 live births was relatively high, but the frequency of invasive treatment and mortality was low, indicating a high proportion of mild pneumothoraces. The lack of patients aged >48 h indicates that most neonatal pneumothoraces now occur very early in life.

Abstract
The novel coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mostly affects adults with limited information on possible vertical transmission from pregnant mothers. We present here two very preterm infants born to mothers with COVID-19, whose respiratory course was significant for initial mild respiratory distress syndrome who developed acute onset severe air leak syndrome at approximately 24 to 36 hours of age requiring thoracentesis. Their respiratory status improved gradually with resolution of air leak and respiratory failure by 2 weeks of age. Both infants tested negative for SARS-CoV-2 by reverse transcriptase-polymerase chain reaction of multiple respiratory specimens collected beyond 24 hours after birth. As the incidence of severe air leak syndrome is relatively low in preterm infants without risk factors, this presentation in two very preterm infants born to mothers with COVID-19 is intriguing and needs to be further evaluated in larger cohorts. If confirmed, this data could potentially be the first step toward generating hypotheses for mechanisms of lung injury, intrauterine transmission, or how to detect COVID-19 in preterm infants. In addition, these data will be critical for developing evidence-based guidelines for perinatal management of these infants as we continue to battle against the COVID-19 pandemic for the foreseeable future.

Abstract
This is a retrospective, single-center observational study to explore the predictors of chest drainage for neonatal pneumothorax. A total of 183 neonates (age ≤28 days) who presented to the Children's Hospital of Soochow University between January 1, 2015 and December 31, 2018 for pneumothorax or developed pneumothorax during a hospital stay were included. Demographic data, clinical presentation, and imaging characteristics of neonatal pneumothorax were collected and analyzed. We used univariate and multivariate logistic regression analyses to determine significant predictors of chest drainage of pneumothorax in neonates. Pneumothorax occurred within 24 h after birth in 131 (71.6%) cases, between 24 and 48 h after birth in 41 (22.4%) cases, and 48 h after birth in 11 (6.0%) cases. Univariate and multivariate logistic regression analyses revealed that lung collapse ≥1/3 on initial chest X-ray (OR 4.99, 95%CI 2.25-11.07), chest retractions (OR 8.12, 95%CI 2.88-22.89), cyanosis (OR 2.25, 95%CI 1.08-4.66), and frothing from mouth (OR 2.49, 95%CI 1.12-5.49) (P<0.05 for all) were significant predictors of the need for chest drainage due to pneumothorax. In conclusion, the thorough evaluation of the above predictive factors can guide treatment and improve patient outcome.

Abstract
PURPOSE This study aimed to elucidate the clinical characteristics of neonates with congenital diaphragmatic hernia (CDH) associated with pneumothorax and evaluate the risk factors for the development of pneumothorax. METHODS A retrospective cohort study was conducted in the 15 institutions participating in the Japanese CDH Study Group. A total of 495 neonates with isolated CDH who were born between 2011 and 2018 were analyzed in this study. RESULTS Among the 495 neonates with isolated CDH, 52 (10.5%) developed pneumothorax. Eighteen (34.6%) patients developed pneumothorax before surgery, while 34 (65.4%) developed pneumothorax after surgery. The log-rank test showed that the cumulative survival rate was significantly lower in patients with pneumothorax than in those without pneumothorax. Univariate analysis revealed significant differences between patients with pneumothorax and those without pneumothorax with regard to the best oxygenation index within 24 h after birth, mean airway pressure (MAP) higher than 16 cmH2O, diaphragmatic defect size, and need for patch closure. Multiple logistic regression analysis indicated that only the MAP was associated with an increased risk of pneumothorax. CONCLUSIONS The cumulative survival rate was significantly lower in isolated CDH patients with pneumothorax than in those without pneumothorax. A higher MAP was a risk factor for pneumothorax in CDH patients.

Abstract
BACKGROUND Transient tachypnea of the newborn (TTN) is characterized by tachypnea and signs of respiratory distress. Transient tachypnea typically appears within the first two hours of life in term and late preterm newborns. Supportive management might be sufficient. Non-invasive (i.e. without endotracheal intubation) respiratory support may, however, be administered to reduce respiratory distress during TTN. In addition, non-invasive respiratory support might improve clearance of lung liquid thus reducing the effort required to breathe, improving respiratory distress and potentially reducing the duration of tachypnea. OBJECTIVES To assess benefits and harms of non-invasive respiratory support for the management of transient tachypnea of the newborn. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 2), MEDLINE (1996 to 19 February 2019), Embase (1980 to 19 February 2019) and CINAHL (1982 to 19 February 2019). We applied no language restrictions. We searched clinical trial registries for ongoing studies. SELECTION CRITERIA Randomized controlled trials, quasi-randomized controlled trials and cluster trials on non-invasive respiratory support provided to infants born at 34 weeks' gestational age or more and less than three days of age with transient tachypnea of the newborn. DATA COLLECTION AND ANALYSIS For each of the included trials, two review authors independently extracted data (e.g. number of participants, birth weight, gestational age, duration of oxygen therapy, need for continuous positive airway pressure [CPAP] and need for mechanical ventilation, duration of mechanical ventilation, etc.) and assessed the risk of bias (e.g. adequacy of randomization, blinding, completeness of follow-up). The primary outcomes considered in this review were need for mechanical ventilation and pneumothorax. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included three trials (150 infants) comparing either CPAP to free-flow oxygen, nasal intermittent mandatory ventilation to nasal CPAP, or nasal high-frequency percussive ventilation versus nasal CPAP. Due to these different comparisons and to high clinical heterogeneity in the baseline clinical characteristics, we did not pool the three studies. The use of CPAP versus free oxygen did not improve the primary outcomes of this review: need for mechanical ventilation (risk ratio [RR] 0.30, 95% confidence interval [CI] 0.01 to 6.99; 1 study, 64 participants); and pneumothorax (not estimable, no cases occurred). Among secondary outcomes, CPAP reduced the duration of tachypnea as compared to free oxygen (mean difference [MD] -21.10 hours, 95% CI -22.92 to -19.28; 1 study, 64 participants). Nasal intermittent ventilation did not reduce the need for mechanical ventilation as compared with CPAP (RR 4.00, 95% CI 0.49 to 32.72; 1 study, 40 participants) or the incidence of pneumothorax (RR 1.00, 95% CI 0.07 to 14.90; 1 study, 40 participants); duration of tachypnea did not differ (MD 4.30, 95% CI -19.14 to 27.74; 1 study, 40 participants). In the study comparing nasal high-frequency ventilation to CPAP, no cases of mechanical ventilation of pneumothorax occurred (not estimable; 1 study, 46 participants); duration of tachypnea was reduced in the nasal high-frequency ventilation group (MD -4.53, 95% CI -5.64 to -3.42; 1 study, 46 participants). The quality of the evidence was very low due to the imprecision of the estimates and unclear risk of bias for detection bias and high risk of bias for reporting bias. Tests for heterogeneity were not applicable for any of the analyses as no studies were pooled. Two trials are ongoing. AUTHORS' CONCLUSIONS There is insufficient evidence to establish the benefit and harms of non-invasive respiratory support in the management of transient tachypnea of the newborn. Though two of the included trials showed a shorter duration of tachypnea, clinically relevant outcomes did not differ amongst the groups. Given the limited and low quality of the evidence available, it was impossible to determine whether non-invasive respiratory support was safe or effective for the treatment of transient tachypnea of the newborn.

Abstract
Background: Pneumothorax is a medical emergency and is associated with a significant increase in morbidity and mortality in newborns. It may lead to acute respiratory failure, systemic hypoperfusion, intraventricular hemorrhage (IVH), and death. There is a paucity of data from developing countries about the epidemiology of pneumothorax. Objective: This descriptive study was planned to study the clinical and epidemiological profile of hospitalized neonates with pneumothorax. Material and methods: In this retrospactive study neonates admitted to Neonatal Intensive Care Unit (NICU) from 1 January 2004 to 31 December 2016 were reviewed.Relevant statistical analyses were done. Results: There were 144,166 live births and 189 inborn cases of pneumothorax; hence, the incidence was 1.3 per 1000 live births. Males outnumbered females by a ratio of 2:1. 50.1% of affected neonates were preterm, mean gestational age being 35.2 ± 3.9 weeks. The mean birth weight was 2238 ± 794 g. Overall median age at diagnosis was 21 h (IQR: 4-48 h), longer in preterm neonates compared to term. Hyaline membrane disease (HMD) was the most common underlying pulmonary disorder. Pneumothorax was drained in 89.2% of tension and only 16.3% of nontension pneumothoraces. Approximately 20% of the neonates were treated with needle aspiration alone and about 24% were treated conservatively. Mortality rate among neonates with pneumothorax was 21.6%. Statistically significant risk factors for mortality were very low birth weight (VLBW) (OR: 2.47, 1.31-4.68), tension pneumothorax (OR: 2.79, 1.05-7.4), and pulmonary hypoplasia (OR: 7.5, 2.8-20.2). Multiple attempts of needle drainage were needed in 2.5% of the cases. The neonates, both term and preterm, requiring drainage had longer duration of hospital stay when compared to those without requirement of drainage. Conclusion: We propose a trial of needle aspiration prior to ICD insertion and intubation which will prevent the complications related to intubation.

Abstract
OBJECTIVE Aim of the study: To determine the impact of lung ultrasonography as an imaging method used to diagnose and monitor newborns with symptomatic pneumothorax and to assess the risk factors for pneumothorax and the outcomes in newborns with symptomatic pneumothorax. PATIENTS AND METHODS Material and methods: A single-centre retrospective study enrolled patients born after 32 weeks of gestation, with a diagnosis of pneumothorax in the first week of life. The 118 patients who were included in the study were divided into two groups. Group A (51 infants) comprised those children who were treated between 2007 and 2010, while group B (n=67) those from the years 2013 to 2016. The children from group A were monitored with repeated chest X-rays. Those from group B received repeated lung ultrasonography supported by chest X-ray in those cases where there was diagnostic uncertainty. Comparison was made between the groups with respect to pneumothorax risk factors, treatment methods and the use of imaging during the period of treatment. The statistical analysis used χ2, Mann-Whitney and Student's t-tests. RESULTS Results: There were no significant demographic or clinical differences between the two groups. Both the use of nCPAP (nasal continuous positive airway pressure) (p<0.001) and diagnosed perinatal asphyxia (p=0.036) were higher in group B. Congenital pneumonia occurred more often in group A (p=0.041). Earlier detection of pneumothorax (p=0.001) and shorter hospital stay (p=0.03) were observed in group B. However, the total number of imaging (lung ultrasound and chest X-ray combined) was higher (p<0.001) in group B. CONCLUSION Conclusion: This study confirmed the usefulness of lung ultrasound in monitoring newborns with pneumothorax, moreover significantly limiting X-ray radiation.

Abstract
Objective: To determine the risk factors and outcomes of persistent pulmonary hypertension of the newborn (PPHN)-associated pneumothorax (PTX).Study design: The medical records of infants diagnosed with PPHN with or without PTX from January 2012 to July 2017 were retrospectively reviewed.Results: Of the 102 included PPHN infants, PTX was found in 32 (31.4%) infants with 43.8% (14/32) mortality. PTX was significantly associated with increased mortality with an odds ratio (OR) of 5.27 (95% confidence interval [CI] 1.96-14.17). Unilateral PTX was more common than bilateral PTX (53.1 versus 46.9%, respectively). Multivariate logistic regression analysis indicated that a 1-minute Apgar score of ≤7 was associated with an increased risk for PTX (adjusted OR = 2.67 [95% CI 1.14-6.25]). In subgroup analysis, each increase of maximum peak inspiratory pressure (PIP) of 1 cmH2O significantly increased the odds of PTX by 1.46 (95% CI 1.02-2.07), while each 1 mmHg increase in arterial partial pressure of oxygen (PaO2) decreased the odds of PTX (adjusted OR = by 0.98 [95% CI 0.97-0.99]).Conclusions: PTX was significantly associated with higher mortality in PPHN infants. Lower Apgar score and increasing PIP in conventional mechanical ventilation were risk factors for PTX. Higher PaO2 was associated with a decreased rate of PTX.

Abstract
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.
