Abstract
OBJECTIVE Exogenous surfactant therapy is vital in managing respiratory distress syndrome (RDS) in preterm infants, with less invasive surfactant administration (LISA) gaining popularity. This study aimed to assess the efficacy and short-term outcomes of LISA using beractant and poractant alfa. STUDY DESIGN In a randomized controlled trial, we enrolled preterm infants (28-33+6 weeks) with RDS requiring surfactant. LISA was employed, with beractant at 100 mg/kg or poractant-alfa at 200 mg/kg. Primary outcome was the need for intubation within 72 hours. RESULTS Among 120 infants, 3.3% in both groups required intubation within 72 hours (p value 1.00, 95% CI 0.14-6.86). No significant differences in secondary outcomes were noted. However, beractant was significantly more economical than poractant-alfa, with a significantly lower surfactant cost and total care cost for infant hospital stays. CONCLUSION Beractant and poractant-alfa exhibit similar efficacy in LISA for preterm infants with RDS. Economic considerations, especially in LMICs, favour beractant. CLINICAL TRIAL REGISTATION: (CTRI/2023/03/050375).

Abstract
Respiratory insufficiency is almost ubiquitous in infants born preterm, with its incidence increasing with lower gestational age. A wide range of respiratory support management strategies are available for these infants, separable into non-invasive and invasive forms of respiratory support. Here we review the history and evolution of respiratory care for the preterm infant and then examine evidence that has emerged to support a non-invasive approach to respiratory management where able. Continuous positive airway pressure (CPAP) is the non-invasive respiratory support mode currently with the most evidence for benefit. CPAP can be delivered safely and effectively and can commence in the delivery room. Particularly in early life, time spent on non-invasive respiratory support, avoiding intubation and mechanical ventilation, affords benefit for the preterm infant by virtue of a lessening of lung injury and hence a reduction in incidence of bronchopulmonary dysplasia. In recent years, enthusiasm for application of non-invasive support has been further bolstered by new techniques for administration of exogenous surfactant. Methods of less invasive surfactant delivery, in particular with a thin catheter, have allowed neonatologists to administer surfactant without resort to endotracheal intubation. The benefits of this approach appear to be sustained, even in those infants subsequently requiring mechanical ventilation. This cements the notion that any reduction in exposure to mechanical ventilation leads to alleviation of injury to the vulnerable preterm lung, with a long-lasting effect. Despite the clear advantages of non-invasive respiratory support, there will continue to be a role for intubation and mechanical ventilation in some preterm infants, particularly for those born <25 weeks' gestation. It is currently unclear what role early non-invasive support has in this special population, with more studies required.

Abstract
BACKGROUND Less-invasive surfactant administration (LISA) is widely used for surfactant delivery to spontaneously breathing preterm infants on nasal CPAP. However, the use of analgesia and/or sedation for the LISA procedure remains controversial. METHODS We conducted a cross-sectional survey of all tertiary neonatal intensive care units (NICUs) in Austria, Germany, and Switzerland to assess current practices of analgosedation for LISA in preterm infants. RESULTS Eighty-eight of 172 (51.2%) NICUs responded to the survey, of which 83 (94.3%) perform LISA. Analgosedation for LISA is used in 60 (72.3%) NICUs. Twenty-eight of those (46.7%) have unit protocols to guide analgosedation while 32 (53.3%) administer medication at the discretion of the attending physician. Ketamine (45.0% of NICUs), propofol (41.7%), fentanyl (21.7%), morphine (20.0%), and midazolam (20.0%) were most frequently used for analgosedation for LISA. Nine (10.7%) NICUs reported the use of pain or distress scores during LISA. CONCLUSION LISA is well established among tertiary NICUs in the German-speaking countries. However, there are considerable variations regarding the use of analgosedation. More evidence is required to guide clinicians seeking to safely and effectively deliver surfactant via a thin catheter to spontaneously breathing preterm infants.

Abstract
ABSTRACT The aim of the study was to investigate ultrasound's diagnostic capabilities for infant respiratory distress syndrome. Retrospective analysis was performed on the clinical information of 96 newborns with respiratory distress syndrome who were treated at our hospital between July 2015 and October 2017. The patients were split into the mild group (n = 55) and the severe group based on the findings of the chest x-ray examinations (n = 41). All neonates underwent an ultrasound examination at baseline, 12 hours after treatment and 24 hours after treatment of pulmonary surfactant (PS). Between the 2 groups, ultrasonographic characteristics and imaging scores were compared between infants with and without PS treatment. When compared with the severe group, the ultrasound score in the mild group was lower ( P < 0.05). Before treatment, there was no statistically significant difference in ultrasound score between the PS treatment group and the non-PS treatment group ( P > 0.05). At each time point after treatment, the ultrasonography score of the non-PS treatment group was greater than that of the PS treatment group ( P < 0.05). Neonatal respiratory distress syndrome severity may be accurately assessed using ultrasound technology. Furthermore, the results of ultrasonography examinations may serve as a significant marker for assessing and measuring the severity of newborn respiratory distress syndrome.

Abstract
BACKGROUND: Management strategies for preterm neonates with respiratory distress syndrome include early initiation of continuous positive airway pressure (CPAP) and titration of fractional inspired oxygen and may include the use of less invasive surfactant administration (LISA) to avoid the need for endotracheal intubation. This randomized trial investigated whether early administration of caffeine and LISA would decrease the need for endotracheal intubation in the first 72 hours of life (HoL) compared with caffeine and CPAP alone. METHODS: Eligible neonates born at 24 weeks 0 days to 29 weeks 6 days of gestational age were randomly assigned to receive intravenous caffeine in the first 2 HoL followed by surfactant administration via the LISA method (intervention) or caffeine followed by CPAP (control). The primary outcome was the frequency of neonates requiring endotracheal intubation or meeting respiratory failure criteria between groups (caffeine and LISA vs. caffeine and CPAP) within the first 72 HoL. Multivariable logistic regression modeling was used to adjust for gestational age strata in normally distributed primary and secondary outcomes. RESULTS: Enrollment occurred between January 2020 and December 2022. Endotracheal intubation or meeting respiratory failure criteria within the first 72 HoL occurred in 21 (23%) of 92 neonates randomly assigned to receive caffeine and LISA compared with 47 (53%) of 88 neonates in the caffeine and CPAP group (odds ratio, 0.258; 95% confidence interval, 0.136 to 0.490; P<0.001), which remained significant after adjusting for gestational age strata (odds ratio, 0.227; 95% confidence interval, 0.112 to 0.460; P<0.001). Adverse events were similar between groups, except bronchopulmonary dysplasia, which occurred in 26% of the LISA group and 39% of the control group (P=0.049). CONCLUSIONS: In preterm neonates supported with CPAP, early caffeine and LISA resulted in a lower frequency of endotracheal intubation within the first 72 HoL.

Abstract
BACKGROUND Training and assessment of operator competence for the less invasive surfactant administration (LISA) procedure vary. This study aimed to obtain international expert consensus on LISA training (LISA curriculum (LISA-CUR)) and assessment (LISA assessment tool (LISA-AT)). METHODS From February to July 2022, an international three-round Delphi process gathered opinions from LISA experts (researchers, curriculum developers, and clinical educators) on a list of items to be included in a LISA-CUR and LISA-AT (Round 1). The experts rated the importance of each item (Round 2). Items supported by more than 80% consensus were included. All experts were asked to approve or reject the final LISA-CUR and LISA-AT (Round 3). RESULTS A total of 153 experts from 14 countries participated in Round 1, and the response rate for Rounds 2 and 3 was >80%. Round 1 identified 44 items for LISA-CUR and 22 for LISA-AT. Round 2 excluded 15 items for the LISA-CUR and 7 items for the LISA-AT. Round 3 resulted in a strong consensus (99-100%) for the final 29 items for the LISA-CUR and 15 items for the LISA-AT. CONCLUSIONS This Delphi process established an international consensus on a training curriculum and content evidence for the assessment of LISA competence. IMPACT This international consensus-based expert statement provides content on a curriculum for the less invasive surfactant administration procedure (LISA-CUR) that may be partnered with existing evidence-based strategies to optimize and standardize LISA training in the future. This international consensus-based expert statement also provides content on an assessment tool for the LISA procedure (LISA-AT) that can help to evaluate competence in LISA operators. The proposed LISA-AT enables standardized, continuous feedback and assessment until achieving proficiency.

Abstract
AIM Less invasive surfactant administration is becoming increasingly popular, but health-care providers may experience some difficulties in achieving the correct positioning of the catheter in the trachea. We compared catheters with marked versus unmarked tips in terms of correct depth positioning in the trachea, total time, number of attempts and participant's opinion on using the device in a manikin model. METHODS A randomised controlled crossover trial of surfactant administration with less invasive surfactant administration catheters with marked versus unmarked tip in a preterm infant manikin. Fifty tertiary hospital consultants and paediatric residents with previous experience in surfactant administration participated. The primary outcome measure was the positioning of the device at the correct depth in the trachea. The secondary outcome measures were the total time and the number of attempts for positioning the device in the trachea, and participant's opinion on using the device. RESULTS Correct depth in the trachea was achieved by 38 (76%) and 28 (56%) participants using the catheters with marked and unmarked tip, respectively (P = 0.04). Median time of device positioning (P = 0.08) and number of attempts (P = 0.13) were not statistically different between the two catheters. Participants found the catheter with the marked tip easier to use (P = 0.007), especially concerning the insertion in the trachea (P = 0.04) and the positioning at the correct depth (P = 0.004). CONCLUSIONS In a preterm manikin model, the marked tip catheter offered a higher chance of achieving the correct depth of the device in the trachea and was favoured by the participants.

Abstract
INTRODUCTION This study was set up to investigate if and to what extent non-pharmacological analgesia is able to provide comfort to very preterm infants (VPI) during less invasive surfactant administration (LISA). METHODS This was a prospective non-randomized multicenter observational study performed in level IV NICUs. Inborn VPI with a gestational age between 220/7 and 316/7 weeks, signs of respiratory distress syndrome, and the need for surfactant replacement were included. Non-pharmacological analgesia was performed in all infants during LISA. In case of failure of the first LISA attempt, additional analgosedation could be administered. COMFORTneo scores during LISA were assessed. RESULTS 113 VPI with a mean gestational age of 27 weeks (+/- 2.3 weeks) and mean birth weight of 946 g (+/- 33 g) were included. LISA was successful at the first laryngoscopy attempt in 81%. COMFORTneo scores were highest during laryngoscopy. At this time point, non-pharmacological analgesia provided adequate comfort in 61% of the infants. 74.4% of lower gestational aged infants (i.e., 220-266 weeks) were within the comfort zone during laryngoscopy compared to 51.6% of higher gestational aged infants (i.e., 270-320 weeks) (p = 0.016). The time point of surfactant administration did not influence the COMFORTneo scores during the LISA procedure. CONCLUSION Non-pharmacological analgesia provided comfort in as much as 61% of the included VPI during LISA. Further research is needed to both develop strategies to identify infants who, despite receiving non-pharmacological analgesia, are at high risk for experiencing discomfort during LISA and define patient-tailored dosage and choice of analgosedative drugs.

Abstract
Less invasive surfactant administration techniques, together with nasal continuous airway pressure (LISA-nCPAP) ventilation, an emerging noninvasive ventilation (NIV) technique in neonatology, are gaining more significance, even in extremely premature newborns (ELBW), under 27 weeks of gestational age. In this review, studies on LISA-nCPAP are compiled with an emphasis on short- and long-term morbidities associated with prematurity. Several perinatal preventative and therapeutic investigations are also discussed in order to start integrated therapies as numerous organ-saving techniques in addition to lung-protective ventilations. Two thirds of immature newborns can start their lives on NIV, and one third of them never need mechanical ventilation. With adjuvant intervention, these ratios are expected to be increased, resulting in better outcomes. Optimized cardiopulmonary transition, especially physiologic cord clamping, could have an additively beneficial effect on patient outcomes gained from NIV. Organ development and angiogenesis are strictly linked not only in the immature lung and retina, but also possibly in the kidney, and optimized interventions using angiogenic growth factors could lead to better morbidity-free survival. Corticosteroids, caffeine, insulin, thyroid hormones, antioxidants, N-acetylcysteine, and, moreover, the immunomodulatory components of mother's milk are also discussed as adjuvant treatments, since immature newborns deserve more complex neonatal interventions.

Abstract
BACKGROUND Sedation to preterm neonates receiving less invasive surfactant administration (LISA) for respiratory distress syndrome is controversial. METHODS Systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies (OS) to evaluate the effect of sedative drugs for LISA on respiratory outcomes and adverse effects. RESULTS One RCT (78 neonates) and two OS (519 neonates) were analyzed in pairwise meta-analysis and 30 studies (2164 neonates) in proportion-based meta-analysis. Sedative drugs might not affect the duration of the procedure [RCT: mean difference (MD) (95% CI); -11 (-90; 67) s; OS: MD 95% CI: -60 (-178; 58) s; low certainty of evidence (CoE)]. Evidence for success at the first attempt and rescue intubation was uncertain (very low CoE). The risk of nasal intermittent positive pressure ventilation [RCT: 1.97 (1.38-2.81); OS: RR, 95% CI: 2.96 (1.46; 6.00), low CoE], desaturation [RCT: RR, 95% CI: 1.30 (1.03; 1.65), low CoE], and apnea [OS: RR, 95% CI: 3.13 (1.35; 7.24), very low CoE] might be increased with sedation. Bradycardia, hypotension, and mechanical ventilation were comparable between groups (low CoE). CONCLUSIONS Use of sedative drugs for LISA temporarily affects the newborn's breathing. Further trials are warranted to explore the use of sedation for LISA. IMPACT The effect of sedative drugs (analgesics, sedatives, anesthetics) compared to the effect of no-sedation for LISA in preterm infants with RDS is underexplored. This systematic review and meta-analysis assesses the impact of sedative drugs compared to no-sedation for LISA on short-term pulmonary outcomes and potential adverse events. Sedative drugs for LISA temporarily affect the newborn's breathing (desaturation, apnea) and increase the need for nasal intermittent positive pressure ventilation. For most outcomes, certainty of evidence is low/very low.

BMC Pulm Med 2022; 22:462. [PMID: 36471386 PMCID: PMC9724250 DOI: 10.1186/s12890-022-02270-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 11/30/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND This study evaluated the effects of less invasive surfactant administration (LISA) and intubation-surfactant-extubation (InSurE) on bronchopulmonary dysplasia (BPD) in preterm infants with respiratory distress syndrome (RDS). METHODS Neonates with respiratory distress syndrome requiring surfactant, with gestational age < 32 weeks and birth weight < 1500 g admitted to our neonatal intensive care unit from January 2018 to December 2019, were retrospectively analyzed. LISA and InSurE were used independently. The incidence of BPD at 36 weeks postmenstrual age, pre-discharge mortality, and need for mechanical ventilation (MV) within 72 h of birth were compared between LISA and InSurE group. Secondary outcomes including necrotizing enterocolitis requiring surgery, retinopathy of prematurity ≥ stage 3, patent ductus arteriosus requiring medical therapy or surgery, and length of hospitalization were analyzed. RESULTS Among the 148 included neonates, there were 46 and 102 infants in LISA group and InSurE group, respectively. There were no significant differences in BPD incidence, the severity of BPD at 36 weeks postmenstrual age, and the rate of MV within the first 72 h after birth between the two groups (P > 0.05, respectively). The incidences of necrotizing enterocolitis requiring surgery, retinopathy of prematurity ≥ stage 3, patent ductus arteriosus requiring medical therapy or surgery, and length of hospitalization did not differ significantly between the two groups (P > 0.05, respectively). CONCLUSIONS For surfactant administration among preterm infants with respiratory distress syndrome, LISA did not decrease bronchopulmonary dysplasia and severity of BPD at 36 weeks postmenstrual age. The benefits of LISA would require further evaluations.

Abstract
Background In respiratory distress syndrome, many neonatology centers worldwide perform minimal invasive surfactant application in premature infants, using small-diameter catheters for endotracheal intubation and surfactant administration. Methods In this single-center, open-label, randomized-controlled trial, preterm infants requiring surfactant administration after birth, using a standardized minimal invasive protocol, were randomized to two different modes of endotracheal catheterization: Flexible charrière-4 feeding tube inserted using Magill forceps (group 1) and semi-rigid catheter (group 2). Primary outcome was duration of laryngoscopy. Secondary outcomes were complication rate (intraventricular hemorrhage, soft-tissue damage in first week of life) and vital parameters during laryngoscopy. Between 2019 and 2020, 31 infants were included in the study. Prior to in-vivo testing, laryngoscopy durations were studied on a neonatal airway mannequin in students, nurses and doctors. Results Mean gestational age and birth weight were 27 + 6/7 weeks and 1009 g; and 28 + 0/7 weeks and 1127 g for group 1 and 2, respectively. Length of laryngoscopy was similar in both groups (61.1 s and 64.9 s) overall (p.77) and adjusted for weight (p.70) or gestational age (p.95). Laryngoscopy failed seven times in group 1 (43.8%) and four times (26.7%) in group 2 (p.46). Longer laryngoscopy was associated with lower oxygen saturation with lowest levels occurring after failed laryngoscopy attempts. Secondary outcomes were similar in both groups. In vitro data on 40 students, 40 nurses and 12 neonatologists showed significant faster laryngoscopy in students and nurses group 2 (p < .0001) unlike in neonatologists (p.13). Conclusion This study showed no difference in laryngoscopy duration in endotracheal catheterization when comparing semi-rigid and flexible catheters for minimal invasive surfactant application in preterm infants. In accordance with preliminary data and in contrast to published in-vitro trials, experienced neonatologists were able to perform endotracheal catheterization using both semi-rigid and flexible catheters at similar rates and ease, in vitro and in vivo.

Cost-saving effect of early less invasive surfactant administration versus continuous positive airway pressure therapy alone for preterm infants with respiratory distress syndrome.

Abstract
OBJECTIVES Early rescue surfactant therapy using less invasive surfactant administration (LISA) can reduce the need for mechanical ventilation and avoid complications in preterm infants with respiratory distress syndrome. The purpose of this study was to estimate the budget impact of LISA compared with management based on continuous positive airway pressure (CPAP) alone and rescue surfactant therapy in case of CPAP failure. METHODS A budget impact model was built comparing LISA with CPAP alone in order to estimate the potential resource consumption and budget impact from the perspective of the National Health Service in England. A literature review was conducted to populate the model. Deterministic and probabilistic sensitivity analyses were conducted to characterise the existing uncertainty and to explore the contribution of individual model parameters to the overall budget impact. RESULTS Early rescue with LISA is expected to reduce resource consumption and costs compared with conservative therapy based on CPAP alone for preterm infants born at 25-32 weeks gestation. Savings are higher for preterm infants of 25-28 weeks (expected budget impact -£5146 per case, 95% credible interval (CrI) -£22 403 to £13, probability of being cost saving 97.4%) than for preterm infants of 29-32 weeks (-£176, 95% CrI -£4279 to £339, probability of being cost saving 85%). The impact of bronchopulmonary dysplasia (BPD) and intraventricular haemorrhage on resource consumption and the expected reduction in the incidence of BPD with LISA are the most influential parameters on the budget. CONCLUSIONS Early rescue with LISA used in preterm infants with respiratory distress syndrome and fraction of inspired oxygen ≥0.3 is expected to be cost saving compared with management based on CPAP alone, particularly in those born at 25-28 weeks gestation.

Should less invasive surfactant administration (LISA) become routine practice in US neonatal units? Pediatr Res 2022; 93:1188-1198. [PMID: 35986148 PMCID: PMC9389478 DOI: 10.1038/s41390-022-02265-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 07/25/2022] [Accepted: 07/29/2022] [Indexed: 11/08/2022]
Abstract
The harmful effects of mechanical ventilation (MV) on the preterm lung are well established. Avoiding MV at birth and stabilization on continuous positive airway pressure (CPAP) decreases the composite outcome of death or bronchopulmonary dysplasia. Although preterm infants are increasingly being admitted to the neonatal intensive care unit on CPAP, centers differ in the ability to manage infants primarily on CPAP. Over the last decade, less invasive surfactant administration (LISA), a method of administering surfactant with a thin catheter, has been devised and has been shown to decrease the need for MV and improve outcomes compared to surfactant administration via an endotracheal tube following intubation. While LISA has been widely adopted in Europe and other countries, its use is not widespread in the United States. This article provides a summary of the existing evidence on LISA, and practical guidance for US units choosing to implement a change of practice incorporating optimization of CPAP and LISA. IMPACT: The accumulated body of evidence for less invasive surfactant administration (LISA), a widespread practice in other countries, justifies its use as an alternative to intubation and surfactant administration in US neonatal units. This article summarizes the current evidence for LISA, identifies gaps in knowledge, and offers practical tips for the implementation of LISA as part of a comprehensive non-invasive respiratory support strategy. This article will help neonatal units in the US develop guidelines for LISA, provide optimal respiratory support for infants with respiratory distress syndrome, improve short- and long-term outcomes of preterm infants, and potentially decrease costs of NICU care.

Abstract
OBJECTIVES The aim of this study was to examine the success rate of less invasive surfactant administration (LISA), to identify early predictive factors for the outcome of LISA, and to compare neonatal outcomes between the LISA failure group and the group of infants who were successfully treated with LISA. DESIGN A retrospective cohort study. PATIENTS Infants born at less than 33 weeks of gestation (n = 158) and treated with LISA for respiratory distress syndrome. RESULTS LISA was successful in 86 cases (54.4%); 72 preterm infants (45.6%) needed additional surfactant therapy and/or mechanical ventilation in the first 72 h (LISA failure). In a multivariate logistic regression analysis, six independent predictors of LISA success were identified: core temperature at the time of admission (adjusted odds ratio (OR): 3.56), dose of poractant alfa (<200 mg/kg; adjusted OR: 0.254), elevated C-reactive protein (>10 mg/L) at 24 h of life (adjusted OR: 0.28), highest respiratory severity score (RSS) during the first hour of life or at the time of LISA (adjusted OR: 0.463), maternal age (adjusted OR: 0.923), and birth weight (adjusted OR: 1.003). The receiver operating curve created by using the identified factors indicates good predictive power with an area under the curve of 0.85. LISA failure was associated with a substantially higher risk of complications. CONCLUSION LISA success can be predicted by variables available before the intervention. Failure of LISA is relatively frequent event in very preterm infants and is associated with adverse outcomes. Prevention of hypothermia during early stabilization and appropriate dosing of surfactant may increase LISA success rates and improve patient outcome.

Abstract
BACKGROUND: Based on the last update of European Consensus Guidelines on Management of Respiratory Distress Syndrome, the following study is new for our clinic approach for minimally invasive respiratory support in preterm infants.
AIM: The aim is to find out if the implementation of several minimally invasive procedures leads to a reduction of the frequency and severity of chronic complications and improved outcomes in extremely premature infants.
MATERIALS AND METHODS: Infants are below 30 gestational weeks, divided into two groups – therapeutic – 37 infants on standardized early respiratory management protocol which includes: High-flow continuous positive airway pressure (20l/min ≥ 15 PEEP) in the delivery room, support of spontaneous breathing and non-invasive mechanical ventilation, avoidance of hypothermia and LISA shortly after birth, and control group – 46 infants that received standard respiratory support (positive pressure ventilation – invasive and non-invasive in the delivery room, most infants ≤ 27 weeks gestational age were intubated and received early surfactant, extubation “when being ready” – usually after few days).
RESULTS: The duration of mechanical ventilation, oxygen therapy, and hospital stay is shorter in the therapeutic group (p < 0.05). Severe bronchopulmonary dysplasia is not found in the interventional group, 26% of the patients in the control group have severe form of the disease (p = 0.001). Severe intraventricular hemorrhages are found in 11% of the infants in the therapeutic group and 28% in the control group (p = 0.06).
CONCLUSION: Due to the changed protocol, we report increased survival of ELBW infants without severe chronic complications. The acute pulmonary injury, acquired in the perinatal period, is directly connected with the development of BPD. For this reason, all the changes that we introduced in our clinic (heat management, support of spontaneous breathing, “open up” lungs – high flow PEEP/CPAP, and LISA during spontaneous breathing) contribute to the lower frequency of severe chronic complications and high percentage of ELBW infants, who do not develop severe BPD.

Abstract
OBJECTIVE To evaluate trends in respiratory care practices and bronchopulmonary dysplasia (BPD) among very preterm infants born in Spain between 2010 and 2019. STUDY DESIGN This was a retrospective cohort study of data obtained from a national population-based database (SEN1500 network). Changes in respiratory care and BPD-free survival of infants with gestational age (GA) of 230-316 weeks and <1500 g were assessed over two 5-year periods. Temporal trends were examined by joinpoint and Poisson regression models and expressed as the annual per cent change and adjusted relative risk (RR) for the change per year. RESULTS A total of 17 952 infants were included. In the second period, infants were less frequently intubated in the delivery room and during neonatal intensive care unit stay. This corresponded with an increase in use of non-invasive ventilation techniques. There were no significant differences between the periods in BPD-free survival or survival without moderate-to-severe BPD. After adjusting for covariates, the RR for the change per year was significant for the following variables: never intubated (RR 1.03, 95% CI 1.02 to 1.04); intubation in the delivery room (RR 0.98, 95% CI 0.97 to 0.99); use of nasal intermittent positive pressure ventilation (RR 1.08, 95% CI 1.05 to 1.11); and BPD-free survival (only in the group with the lowest GA; RR 0.98, 95% CI 0.97 to 0.99). CONCLUSION Our findings reveal significant changes in respiratory care practices between 2009 and 2019. Despite an increase in use of non-invasive respiratory strategies, BPD-free survival did not improve and even worsened in the group with the lowest GA (230-256).

Abstract
Extremely preterm infants who must suddenly support their own gas exchange with lungs that are incompletely developed and lacking adequate amount of surfactant and antioxidant defenses are susceptible to lung injury. The decades-long quest to prevent bronchopulmonary dysplasia has had limited success, in part because of increasing survival of more immature infants. The process must begin in the delivery room with gentle assistance in establishing and maintaining adequate lung aeration, followed by noninvasive support and less invasive surfactant administration. Various modalities of invasive and noninvasive support have been used with varying degree of effect and are reviewed in this article.

Abstract
INTRODUCTION Less-invasive surfactant administration (LISA) under continuous positive airway pressure is increasingly used for the treatment of neonatal respiratory distress. Different procedures are described, but data on the optimal catheter insertion depth are sparse. OBJECTIVE To generate data for recommending an optimal catheter insertion depth in LISA. METHODS We examined 112 anterior-posterior chest X-rays from intubated infants and determined the carina's vertebral projection, whenever possible. After that, distances between the middle of cervical vertebra 4 (C4) and thoracic vertebra 2 and the middle of C4 to thoracic vertebra 3, respectively, were measured. Results were plotted against infant's weight. RESULTS A weight-based chart and recommendations for the optimal intratracheal catheter position in infants with a body weight between 350 and 4000 g were created. CONCLUSIONS Generated data offer standardisation and may thus help to find a balance between risk of surfactant reflux and unilateral surfactant administration.

Abstract
Purpose: The study aimed to examine whether prophylactic surfactant replacement therapy (SRT) with less invasive surfactant administration (LISA) by tracheal catheterization in a group of spontaneously breathing preterm infants would improve clinical outcomes compared to prophylactic SRT with the INtubation-SURfactantExtubation (INSURE) method.Methods: We compared 20 spontaneously breathing preterm infants, 25 to 29 weeks of gestation or with a birth weight of less than 1,250 g, treated with prophylactic SRT using a gastric tube (LISA group), to the 20 spontaneously breathing preterm infants matched by gestational age and birth weight, managed with prophylactic SRT via the INSURE method (INSURE group, historical control).Results: The LISA group had lower rates of mechanical ventilation (MV) 72 hours after birth (P=0.019) and at any time (P=0.025), lower frequency of bradycardia during SRT (P=0.031), and lower median duration of MV than the INSURE group (P=0.038). In multivariate analysis, the LISA method was associated with a significantly lower likelihood of receiving invasive ventilation during hospitalization (odds ratio [OR], 0.029; 95% confidence interval [CI], 0.001 to 0.938; P=0.046) and a decreased frequency of bradycardia during SRT (OR, 0.020; 95% CI, 0.001 to 0.535; P=0.020) as compared to the INSURE method.Conclusion: Prophylactic SRT using LISA via tracheal catheterization in preterm infants may significantly reduce exposure to MV during hospitalization and bradycardia during surfactant administration.

Abstract
For preterm infants with respiratory distress syndrome, delivery of surfactant via brief intubation (INtubate, SURfactant, Extubate; InSurE) has been the standard technique of surfactant administration. However, this method requires intubation and positive pressure ventilation. It is thought that even the short exposure to positive pressure inflations may be enough to initiate the cascade of events that lead to lung injury in the smallest neonates. In an effort to avoid tracheal intubation and positive pressure ventilation, several alternative and less invasive techniques of exogenous surfactant administration have been developed over the years. These have been investigated in clinical studies, including randomized clinical trials, and have demonstrated advantages such as a decrease in the need for mechanical ventilation and incidence of bronchopulmonary dysplasia. These newer techniques of surfactant delivery also have the benefit of being easier to perform. Surfactant delivery via pharyngeal instillation, laryngeal mask, aerosolization, and placement of a thin catheter are being actively pursued in research. We present a contemporary review of surfactant administration for respiratory distress syndrome via these alternative methods in the hope of guiding physicians in their choices for surfactant application in the neonatal intensive care unit.

Anatomic accuracy, physiologic characteristics, and fidelity of very low birth weight infant airway simulators. Pediatr Res 2022; 92:783-790.

Abstract
BACKGROUND Medical simulation training requires realistic simulators with high fidelity. This prospective multi-center study investigated anatomic precision, physiologic characteristics, and fidelity of four commercially available very low birth weight infant simulators. METHODS We measured airway angles and distances in the simulators Premature AirwayPaul (SIMCharacters), Premature Anne (Laerdal Medical), Premie HAL S2209 (Gaumard), and Preterm Baby (Lifecast Body Simulation) using computer tomography and compared these to human cadavers of premature stillbirths. The simulators' physiologic characteristics were tested, and highly experienced experts rated their physical and functional fidelity. RESULTS The airway angles corresponded to those of the reference cadavers in three simulators. The nasal inlet to glottis distance and the mouth aperture to glottis distance were only accurate in one simulator. All simulators had airway resistances up to 20 times higher and compliances up to 19 times lower than published reference values. Fifty-six highly experienced experts gave three simulators (Premature AirwayPaul: 5.1 ± 1.0, Premature Anne 4.9 ± 1.1, Preterm Baby 5.0 ± 1.0) good overall ratings and one simulator (Premie HAL S2209: 2.8 ± 1.0) an unfavorable rating. CONCLUSION The simulator physiology deviated significantly from preterm infants' reference values concerning resistance and compliance, potentially promoting a wrong ventilation technique. IMPACT Very low birth weight infant simulators showed physiological properties far deviating from corresponding patient reference values. Only ventilation with very high peak pressure achieved tidal volumes in the simulators, as aimed at in very low birth weight infants, potentially promoting a wrong ventilation technique. Compared to very low birth weight infant cadavers, most tested simulators accurately reproduced the anatomic angular relationships, but their airway dimensions were relatively too large for the represented body. The more professional experience the experts had, the lower they rated the very low birth weight infant simulators.

Abstract
IMPORTANCE The benefits of surfactant administration via a thin catheter (minimally invasive surfactant therapy [MIST]) in preterm infants with respiratory distress syndrome are uncertain. OBJECTIVE To examine the effect of selective application of MIST at a low fraction of inspired oxygen threshold on survival without bronchopulmonary dysplasia (BPD). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial including 485 preterm infants with a gestational age of 25 to 28 weeks who were supported with continuous positive airway pressure (CPAP) and required a fraction of inspired oxygen of 0.30 or greater within 6 hours of birth. The trial was conducted at 33 tertiary-level neonatal intensive care units around the world, with blinding of the clinicians and outcome assessors. Enrollment took place between December 16, 2011, and March 26, 2020; follow-up was completed on December 2, 2020. INTERVENTIONS Infants were randomized to the MIST group (n = 241) and received exogenous surfactant (200 mg/kg of poractant alfa) via a thin catheter or to the control group (n = 244) and received a sham (control) treatment; CPAP was continued thereafter in both groups unless specified intubation criteria were met. MAIN OUTCOMES AND MEASURES The primary outcome was the composite of death or physiological BPD assessed at 36 weeks' postmenstrual age. The components of the primary outcome (death prior to 36 weeks' postmenstrual age and BPD at 36 weeks' postmenstrual age) also were considered separately. RESULTS Among the 485 infants randomized (median gestational age, 27.3 weeks; 241 [49.7%] female), all completed follow-up. Death or BPD occurred in 105 infants (43.6%) in the MIST group and 121 (49.6%) in the control group (risk difference [RD], -6.3% [95% CI, -14.2% to 1.6%]; relative risk [RR], 0.87 [95% CI, 0.74 to 1.03]; P = .10). Incidence of death before 36 weeks' postmenstrual age did not differ significantly between groups (24 [10.0%] in MIST vs 19 [7.8%] in control; RD, 2.1% [95% CI, -3.6% to 7.8%]; RR, 1.27 [95% CI, 0.63 to 2.57]; P = .51), but incidence of BPD in survivors to 36 weeks' postmenstrual age was lower in the MIST group (81/217 [37.3%] vs 102/225 [45.3%] in the control group; RD, -7.8% [95% CI, -14.9% to -0.7%]; RR, 0.83 [95% CI, 0.70 to 0.98]; P = .03). Serious adverse events occurred in 10.3% of infants in the MIST group and 11.1% in the control group. CONCLUSIONS AND RELEVANCE Among preterm infants with respiratory distress syndrome supported with CPAP, minimally invasive surfactant therapy compared with sham (control) treatment did not significantly reduce the incidence of the composite outcome of death or bronchopulmonary dysplasia at 36 weeks' postmenstrual age. However, given the statistical uncertainty reflected in the 95% CI, a clinically important effect cannot be excluded. TRIAL REGISTRATION anzctr.org.au Identifier: ACTRN12611000916943.

Abstract
Less invasive surfactant administration (LISA) has been introduced at our tertiary Level IV perinatal center since 2016 with an unsatisfactory success rate, which we attributed to an inconsistent, non-standardized approach and ambiguous patient inclusion criteria. This study aimed to improve the LISA success rate to at least 75% within 12 months by implementing a highly standardized LISA approach combined with team training. The Plan Do Study Act method of quality improvement was used for this initiative. Baseline assessment included a review of patient medical records 12 months before the intervention regarding patient characteristics, method success rate, respiratory, and adverse outcomes. A multi-professional team developed a standardized LISA approach and a training program including an educational film, checklists, pocket cards, and team briefings. Twenty-one preterm infants received LISA before and 24 after the intervention. The mean LISA success rate improved from 62% before the intervention to 92% (p = 0.029) after the intervention. Implementing a highly standardized LISA approach and multi-professional team training significantly improved the methods’ success rate.

Abstract
AIM Minimally invasive surfactant therapy (MIST) is used to deliver exogenous surfactant to preterm neonates with respiratory distress syndrome. The objective of this study was to review the use of MIST in moderate to late preterm neonates born in a non-tertiary unit. METHODS A retrospective review was conducted of neonates receiving MIST in a non-tertiary unit. MIST was considered in neonates requiring continuous positive airway pressure ≥ 6 cm H2 O and fraction of inspired oxygen ≥ 0.35. The Hobart method was used to deliver exogenous surfactant. The primary outcome was improvement in respiratory function. Secondary outcomes include intubation and transfer to a tertiary unit. RESULTS Between 2016 and 2020, 23 infants were treated with MIST. The median gestational age was 33+5 ± 2.7 weeks and mean age of surfactant administration was 6.6 ± 3.6 h. Surfactant administration resulted in a reduction in median fraction of inspired oxygen from 0.3 to 0.21 at 4 h post MIST (P value: 0.001), and a reduction in median positive end-expiratory pressure (PEEP) from 7 to 6 cm H2 O at 24 h post MIST (P value: 0.003). Continuous positive airway pressure support was required for a median period of 3.5 days following MIST. There was respiratory improvement in 52 and 65% of neonates at 4 and 24 h, respectively, following MIST. The incidence of intubation was 13% and transfer to a tertiary unit was 44%. CONCLUSIONS Use of MIST at this unit improved respiratory outcomes in moderate to late preterm neonates with respiratory distress syndrome. This procedure was well tolerated with few adverse events. Further research evaluating the efficacy of MIST in other non-tertiary units is warranted.

Abstract
Various less invasive surfactant administration strategies like surfactant replacement therapy via thin catheters, laryngeal mask airway, pharyngeal instillation, and nebulized surfactant are increasingly being practiced to avoid the harmful effects of endotracheal intubation and ventilation. Numerous studies have been done to study surfactant replacement via thin catheters whereas little data is available for other methods. However, there are variations in premedication policies, type of respiratory support used in these studies. Surfactant delivery using thin catheters has been reported to be associated with decrease in the need for mechanical ventilation (MV), duration of MV, bronchopulmonary dysplasia and neonatal mortality. With the current evidence, among all the available surfactant delivery methods, the one using thin catheters appears to be the most feasible and beneficial to improve clinical neonatal outcomes.

Abstract
OBJECTIVES To compare surfactant administration via thin catheters, laryngeal mask, nebulisation, pharyngeal instillation, intubation and surfactant administration followed by immediate extubation (InSurE) and no surfactant administration. DESIGN Network meta-analysis. SETTING Medline, Scopus, CENTRAL, Web of Science, Google-scholar and Clinicaltrials.gov databases were systematically searched from inception to 15 February 2020. PATIENTS Preterm neonates with respiratory distress syndrome. INTERVENTIONS Less invasive surfactant administration. MAIN OUTCOME MEASURES The primary outcomes were mortality, mechanical ventilation and bronchopulmonary dysplasia. RESULTS Overall, 16 randomised controlled trials (RCTs) and 20 observational studies were included (N=13 234). For the InSurE group, the median risk of mortality, mechanical ventilation and bronchopulmonary dysplasia were 7.8%, 42.1% and 10%, respectively. Compared with InSurE, administration via thin catheter was associated with significantly lower rates of mortality (OR: 0.64, 95% CI: 0.54 to 0.76), mechanical ventilation (OR: 0.43, 95% CI: 0.29 to 0.63), bronchopulmonary dysplasia (OR: 0.57, 95% CI: 0.44 to 0.73), periventricular leukomalacia (OR: 0.66, 95% CI: 0.53 to 0.82) with moderate quality of evidence and necrotising enterocolitis (OR: 0.67, 95% CI: 0.41 to 0.9, low quality of evidence). No significant differences were observed by comparing InSurE with administration via laryngeal mask, nebulisation or pharyngeal instillation. In RCTs, thin catheter administration lowered the rates of mechanical ventilation (OR: 0.39, 95% CI: 0.26 to 0.60) but not the incidence of the remaining outcomes. CONCLUSION Among preterm infants, surfactant administration via thin catheters was associated with lower likelihood of mortality, need for mechanical ventilation and bronchopulmonary dysplasia compared with InSurE. Further research is needed to reach firm conclusions about the efficacy of alternative minimally invasive techniques of surfactant administration.

Abstract
Pain recognition and management continues to be a challenge for health professionals in Neonatal Intensive Care Units. Many of the patients are routinely exposed to repeated painful experiences with demonstrated short- and long-term consequences. Preterm babies are a vulnerable high-risk population. Despite international recommendations, pain remains poorly assessed and managed in many Neonatal Intensive Care Units. Due to there being no general protocol, there is significant variability as regards the guidelines for the approach and treatment of pain between the different Neonatal Intensive Care Units. The objective of this article is to review and assess the general principles of pain in the initial stages of development, its recognition through the use of standardised scales. It also includes its prevention and management with the combination of pharmacological and non-pharmacological measures, as well as to establish recommendations that help alleviate pain in daily clinical practice by optimising pain and stress control in the Neonatal Intensive Care Units.

Abstract
BACKGROUND Minimally invasive surfactant therapy (MIST) is a promising mode of administration that offers the potential to limit barotrauma and prevent lung injury in preterm infants with respiratory distress syndrome (RDS). OBJECTIVE This study assessed the effects of the implementation of MIST on safety and efficacy in infants who met criteria for surfactant administration and were treated by MIST as compared with a historical control group treated with surfactant via an endotracheal tube during mechanical ventilation. METHODS This retrospective study included infants born between 2012 and 2017 who met the following inclusion criteria: gestational age 23-36 + 6 weeks, a diagnosis of RDS requiring at least 30% oxygen with or without nasal continuous positive airway pressure (nCPAP). MIST was introduced in 2014 and a comparison was made between the study group who received MIST and the control group who met similar criteria and received surfactant via an endotracheal tube during mechanical ventilation. RESULTS No significant differences were found between the groups in baseline and demographic data. Severity of initial disease, assessed by the CRIB II score, was similar in the two groups (control 4.6 ± 2.8, MIST 4.4 ± 2.4, p=.995). The requirement for oxygen during the first 3 d of life was significantly lower (area under the curve [AUC]: p=.001) in the MIST group as assessed by the AUC. Likewise, the mean days of oxygen requirement were significantly lower in the MIST group (Control: 10.3 d, MIST: 5.9 d, p=.04). Only six infants in the MIST group (13%) subsequently required intubation for mechanical ventilation, only one of whom adjacent to the procedure. A modest reduction in duration of ventilation was also noted. Duration of admission was 32 ± 23 d in the control group and 26 ± 21 d in the MIST group, p=.061. No significant differences were found between the groups in the incidence of major morbidities or mortality. No major adverse events related to the procedure were observed. CONCLUSIONS Transition to MIST was associated with significantly reduced need for oxygen, mechanical ventilation and surfactant, and a borderline shortened NICU admission.

Abstract
Early therapeutic effect of intratracheally (IT)-administered extracellular vesicles secreted by mesenchymal stem cells (MSC-EVs) has been demonstrated in a rat model of bronchopulmonary dysplasia (BPD) involving hyperoxia exposure in the first 2 postnatal weeks. The aim of this study was to evaluate the protective effects of IT-administered MSC-EVs in the long term. EVs were produced from MSCs following GMP standards. At birth, rats were distributed in three groups: (a) animals raised in ambient air for 6 weeks (n = 10); and animals exposed to 60% hyperoxia for 2 weeks and to room air for additional 4 weeks and treated with (b) IT-administered saline solution (n = 10), or (c) MSC-EVs (n = 10) on postnatal days 3, 7, 10, and 21. Hyperoxia exposure produced significant decreases in total number of alveoli, total surface area of alveolar air spaces, and proliferation index, together with increases in mean alveolar volume, mean linear intercept and fibrosis percentage; all these morphometric changes were prevented by MSC-EVs treatment. The medial thickness index for <100 µm vessels was higher for hyperoxia-exposed/sham-treated than for normoxia-exposed rats; MSC-EV treatment significantly reduced this index. There were no significant differences in interstitial/alveolar and perivascular F4/8-positive and CD86-positive macrophages. Conversely, hyperoxia exposure reduced CD163-positive macrophages both in interstitial/alveolar and perivascular populations and MSC-EV prevented these hyperoxia-induced reductions. These findings further support that IT-administered EVs could be an effective approach to prevent/treat BPD, ameliorating the impaired alveolarization and pulmonary artery remodeling also in a long-term model. M2 macrophage polarization could play a role through anti-inflammatory and proliferative mechanisms.

Abstract
INTRODUCTION Less-invasive surfactant administration (LISA) is a method of surfactant delivery to preterm infants for treating respiratory distress syndrome (RDS), which can reduce the composite risk of death or bronchopulmonary dysplasia and the time on mechanical ventilation. METHODS A systematic literature search of studies published up to April 2021 on minimally invasive catheter surfactant delivery in preterm infants with RDS was conducted. Based on these studies, with parental feedback sought via an online questionnaire, 9 UK-based specialists in neonatal respiratory disease developed their consensus for implementing LISA. Recommendations were developed following a modified, iterative Delphi process using a questionnaire employing a 9-point Likert scale and an a priori level of agreement/disagreement. RESULTS Successful implementation of LISA can be achieved by training the multidisciplinary team and following locally agreed guidance. From the time of the decision to administer surfactant, LISA should take <30 min. The comfort of the baby and requirements to maintain non-invasive respiratory support are important. While many infants can be managed without requiring additional sedation/analgesia, fentanyl along with atropine may be considered. Parents should be provided with sufficient information about medication side effects and involved in treatment discussions. CONCLUSION LISA has the potential to improve outcomes for preterm infants with RDS and can be introduced as a safe and effective part of UK-based neonatal care with appropriate training.

Abstract
Less invasive surfactant administration (LISA) is an effective, minimally invasive technique of administering surfactant to infants with respiratory distress syndrome. While termed less invasive, LISA still requires airway instrumentation with direct laryngoscopy, thus may be considered painful. However, the issue of whether or not to routinely sedate infants for LISA remains contentious, with significant variation in practice between centres. Proponents for giving pharmacological analgesia and/or sedation predominantly focus on patient comfort during the procedure. However, those who favour non-pharmacological measures of pain management focus on the potential for procedural success without the risk of adverse events, such as respiratory depression and potentially the need for escalation to intubation, which may occur with pharmacological agents. The neonatal population who may benefit from LISA is varied. Due to this variety in presentation type, gestational age, and unit experience, there is a need to provide an individualized, tailored approach to sedation and analgesia for these infants. Using a blanket approach to sedation will lead to infants being exposed to sedative medications on the assumption of potential distress, rather than in response to signs of actual distress. This places the infant at risk of the adverse reactions, potentially without them ever having needed the beneficial effect of the medications. This seems an unnecessary risk. This article explores the ethical arguments pertaining to analgesia and sedation during the LISA technique, concluding that a standardized approach to the usage of pharmacological sedation is undesirable. Moreover, we maintain that procedural analgesia and sedation should be based on individualized, infant-centred assessment, rather than on a rigid, standardized approach.

Abstract
Bronchopulmonary dysplasia (BPD) is a major complication in prematurely born infants. Pulmonary hypertension (PH) associated with BPD (BPD-PH) is characterized by alveolar diffusion impairment, abnormal vascular remodeling, and rarefication of pulmonary vessels (vascular growth arrest), which lead to increased pulmonary vascular resistance and right heart failure. About 25% of infants with moderate to severe BPD develop BPD-PH that is associated with high morbidity and mortality. The recent evolution of broader PH-targeted pharmacotherapy in adults has opened up new treatment options for infants with BPD-PH. Sildenafil became the mainstay of contemporary BPD-PH therapy. Additional medications, such as endothelin receptor antagonists and prostacyclin analogs/mimetics, are increasingly being investigated in infants with PH. However, pediatric data from prospective or randomized controlled trials are still sparse. We discuss comprehensive diagnostic and therapeutic strategies for BPD-PH and briefly review the relevant differential diagnoses of parenchymal and interstitial developmental lung diseases. In addition, we provide a practical framework for the management of children with BPD-PH, incorporating the modified definition and classification of pediatric PH from the 2018 World Symposium on Pulmonary Hypertension, and the 2019 EPPVDN consensus recommendations on established and newly developed therapeutic strategies. Finally, current gaps of knowledge and future research directions are discussed. IMPACT: PH in BPD substantially increases mortality. Treatment of BPD-PH should be conducted by an interdisciplinary team and follow our new treatment algorithm while still kept tailored to the individual patient. We discuss recent developments in BPD-PH, make recommendations on diagnosis, monitoring and treatment of PH in BPD, and address current gaps of knowledge and potential research directions. We provide a practical framework, including a new treatment algorithm, for the management of children with BPD-PH, incorporating the modified definition and classification of pediatric PH (2018 WSPH) and the 2019 EPPVDN consensus recommendations on established and newly developed therapeutic strategies for BPD-PH.

Abstract
Background: Differences in management and outcomes of extremely preterm infants have been reported across European countries. Implementation of standardized guidelines and interventions within existing neonatal care facilities can improve outcomes of extremely preterm infants. This study evaluated whether a multifactorial educational training (MET) course in Vienna focusing on the management of extremely preterm infants had an impact on the management of extremely preterm infants in Central-Eastern European (CEE) countries. Methods: Physicians and nurses from different hospitals in CEE countries participated in a two-day MET in Vienna, Austria with theoretical lectures, bedside teaching, and simulation trainings. In order to evaluate the benefit of the workshops, participants had to complete pre- and post-workshop questionnaires, as well as follow-up questionnaires three and twelve months after the MET. Results: 162 participants from 15 CEE countries completed the two-day MET at our department. Less invasive surfactant administration (LISA) was only used by 39% (63/162) of the participants. After the MET, 80% (122/152) were planning to introduce LISA, and 66% (101/152) were planning to introduce regular simulation training, which was statistically significantly increased three and twelve months after the MET. Thirty-six percent and 57% of the participants self-reported improved outcomes three and twelve months after the MET, respectively. Conclusion: Our standardized training in Vienna promoted the implementation of different perinatal concepts including postnatal respiratory management using LISA as well as regular simulation trainings at the participants' home departments. Moreover, our MET contributed to dissemination of guidelines, promoted best-practice, and improved self-reported outcomes.

Less invasive surfactant administration versus endotracheal surfactant instillation followed by limited peak pressure ventilation in preterm infants with respiratory distress syndrome in China: study protocol for a randomized controlled trial.

Abstract
Background Less invasive surfactant administration (LISA) is a way of giving surfactant without endotracheal intubation and has shown to be promising in reducing the incidence of bronchopulmonary dysplasia (BPD) in preterm infants. However, the mechanism underlying its beneficial effect and variations in the technique of administration may prevent its widespread use. This trial aims to evaluate the effects of two methods of surfactant administration, LISA or endotracheal surfactant administration followed by low peak pressure (LPPSA) ventilation, in preterm infants with respiratory distress syndrome (RDS). Methods The LISA Or Low Peak Pressure trial is to be conducted in 14 tertiary neonatal intensive care units in China. A total of 600 preterm infants born with gestational age between 250/7 and 316/7 weeks and with a primary diagnosis of RDS will be involved in the study. Infants will be randomized to the LISA or LPPSA group when surfactant therapy is indicated. Primary outcomes include mortality, severity of bronchopulmonary dysplasia at 36 weeks of postmenstrual age (PMA), and mechanical ventilation (MV) in the first 72 h of life. Secondary outcomes include the days of MV, duration of all sorts of non-invasive respiratory support, fraction of inspired oxygen, oxygen saturation before and after surfactant administration, and time required to perform the procedure for surfactant administration. The incidence of comorbidities, including retinopathy of prematurity (ROP), necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), hemodynamically significant patent ductus arteriosus (hsPDA), pneumothorax, and massive pulmonary hemorrhage within 48 h of surfactant administration, and the failure rates of each technique will be determined. Discussion Data from recent systematic review and meta-analysis have suggested a possible improvement in outcomes of preterm infants with RDS by the LISA technique. However, robust evidence is lacking. Why LISA plays a potential role in reducing respiratory morbidity, mainly BPD in preterm infants, remains unclear. The possible explanations are the active and uninterrupted delivery of continuous positive airway pressure during the LISA procedure and the avoidance of complications caused by intubation and relatively high pressure/volume ventilation following surfactant administration. We hypothesized that LISA’s effectiveness lies mainly in avoiding relatively high-pressure positive ventilation immediately following surfactant administration. Thus, this multicenter randomized controlled trial will focus on issues of endotracheal intubation and the pressure/volume used during conventional surfactant administration. The effectiveness, safety and comorbidities of preterm infants following LISA or LPPSA will be evaluated. Trial registration Chinese Clinical Trial Registry: ChiCTR1900020970.

Abstract
BACKGROUND Hyaline membrane disease contributes majorly to preterm mortality, particularly in the developing world. There are two animal-derived surfactants available in South Africa: poractant-alfa (120 mg/1.5 ml) and beractant (100 mg/4 ml). At equivalent doses, studies have shown no difference in mortality or morbidity, although there are limited data from the developing world. Both surfactants have been available for use at Groote Schuur Hospital in Cape Town but due to policy change, poractant-alfa was no longer available from November 2014. Due to weight-based dosing charts, infants who were given poractant-alfa received 20% higher dosages of phospholipid. METHODS A before-and-after policy change non-experimental study was performed including infants from 2013 to 2015. Infants weighing <1500 g were recruited by identifying them from the surfactant register and further data were obtained from patient records. Data fields included infant weight, gestation, respiratory support and outcomes. RESULTS Two hundred and eight infants were included. One hundred and eight received beractant and 100 received poractant-alfa. The mean birth weight was 1031 g and gestational age 28.8 weeks. Seventy-nine percent of the infants received surfactant via the INSURE (intubation, surfactant and extubation) method. The combined outcome for death or bronchopulmonary dysplasia was 35.3% in the beractant group and 36% in the poractant-alfa group (p = 0.902). All secondary outcomes including neonatal morbidities, oxygen at 28 days or length of ventilation were not statistically significant. CONCLUSION There were no significant differences in outcomes between the two groups of infants who received different surfactants at the dosages used in our unit. This is one of the few studies of this type performed in a low- and middle-income countries.

Abstract
Objective There are differences in the adoption rates of less invasive surfactant administration (LISA) worldwide. We aimed to describe and analyze the process of LISA introduction at the country level. Methods A standardized training program (33 courses covering >500 neonatologists) was followed by a cohort study. Data regarding consecutive LISA procedures were acquired over 12 months in 31 tertiary neonatal centers, using a dedicated on-line platform. Results Of 500 LISA procedures, 75% were performed by specialists and 25% by residents. The mean percentage share of LISA in all surfactant therapies was 24%, which represents a 6-fold increase compared to previous years. After 12 months, 76% of the procedures were rated “easy/very easy” vs 59% at baseline (p<0.05). Surfactant re-treatment rate was 15%. Twenty-three percent of infants required mechanical ventilation within 72 hours of life. Oxygen desaturation and surfactant reflux were the most frequent complications. Unlike previous reports describing exclusive use of nasal continuous positive airway pressure (nCPAP) during LISA, majority of procedures (63%) were carried out using nasal intermittent positive pressure ventilation (NIPPV) or Bilevel Positive Airway Pressure (BiPAP). Efficacy of LISA with NIPPV or BiPAP was not significantly different from that with nCPAP (22.4% vs 24.5% of cases requiring intubation). Ventilation was provided with nasal cannulas or nasal masks (90%) and rarely with “RAM” cannulas or nasopharyngeal tubes. Rigid catheters were preferred (88.4%); tracheal insertion was successful at first attempt in 87% of cases. Majority of infants (79%) received no premedication prior to the procedure and almost all were given caffeine citrate. Median time of instillation was 1.5 minutes. Conclusions The LISA procedure does not appear to be technically difficult to master. Training combining theory with practical exercises is an efficient implementation strategy. Variations in adoption rates indicate the need for additional, more personalized teachings in some centers.

Abstract
PURPOSE OF REVIEW The purpose of this review is to describe current concepts in the field of Less Invasive Surfactant Administration (LISA). The use of continuous positive airway pressure (CPAP) has become standard for the treatment of premature infants with respiratory problems throughout the world. However, if CPAP fails, technologies like LISA are needed that can combine surfactant delivery and spontaneous breathing with the support of noninvasive modes of ventilation. RECENT FINDINGS LISA with thin catheters has been in use in Germany for more than 15 years. In the last 5 years, there was substantial interest in this method around the world. Randomized studies and recent metaanalyses indicate that the LISA technique helps to avoid mechanical ventilation especially in emerging respiratory distress syndrome (RDS). LISA is also associated with improved outcomes of preterm infants, specifically in the prevention of bronchopulmonary dysplasia (BPD) and intracranial hemorrhage (ICH). By now, a variety of different LISA catheters, devices and techniques have been described. However, most of the technologies are still connected with the unpleasant experience of laryngoscopy for the affected infants, so that the search for even less invasive techniques, for example, surfactant application by nebulization, goes on. SUMMARY Maintenance of spontaneous breathing with support by the LISA technique holds big promise in the care of preterm infants. Patient comfort and lower complication rates are strong arguments to further investigate and promote the LISA approach. Open questions include exact indications for different patient groups, the usefulness of devices/catheters that have recently been built for the LISA technique and -- perhaps most urgently -- the issue of analgesia/sedation during the procedure. Studies on long-term outcome after LISA are under way.

[PMID: 32014122 DOI: 10.1016/s2352-4642(19)30405-5] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 10/17/2019] [Accepted: 11/05/2019] [Indexed: 12/13/2022]
Abstract
Surfactant is a cornerstone of neonatal critical care, and the presumed less (or minimally) invasive techniques for its administration have been proposed to reduce invasiveness of neonatal critical care interventions. These techniques are generally known as less invasive surfactant administration (LISA) and have quickly gained popularity in some neonatal intensive care units. Despite the increase in the use of LISA, we believe that the pathobiological background supporting its possible clinical benefits is unclear. Similarly, it is unclear whether there are any ignored drawbacks, as LISA has been tested in only a few trials and some physiopathological issues seem to have gone unnoticed. Active research is warranted to fill these knowledge gaps before LISA can be firmly recommended. In this Viewpoint, we provide an in-depth analysis of LISA techniques, based on physiological and pathobiological factors, followed by a critical appraisal of available clinical data, and highlight some possible future research directions.

Abstract
Less invasive surfactant administration (LISA) is a method to deliver surfactant to spontaneously breathing premature infants via a thin catheter. Here we report the two-year outcome from the AMV (avoid mechanical ventilation) study, the first randomized controlled trial on this mode of surfactant delivery. No statistically significant differences in weight, length or neurodevelopmental outcome (Bayley II scores) were found between the LISA intervention group (n = 95) and the control group (n = 84) that received standard treatment.Conclusion: No differences in outcome were observed at 2 years. LISA seems safe in that aspect. What is Known: • LISA is a method that is in increasing use for surfactant delivery to spontaneously breathing infants. LISA reduces the need for mechanical ventilation. What is New: • Outcome data at 2 years from the first randomized study with LISA raise no safety concerns in comparison to a group of infants that received standard treatment.
