Abstract
To compare the therapeutic effect of less invasive surfactant administration (LISA) followed by synchronized nasal intermittent positive pressure ventilation (SNIPPV) and traditional intubate-Surfactant-Extubate (InSurE) strategy for the treatment of neonatal respiratory distress syndrome (NRDS). A single-center, non-randomized and single- blinded study Tertiary neonatal intensive care unit 89 infants enrolled were preterm with gestational age < 366/7 weeks and clinically diagnosed with neonatal RDS (NRDS) Interventions: 32 infants were assigned to the LISA + SNIPPV group and 57 infants to the InSurE + nCPAP group. No statistically significant differences were noted in the baseline characteristics of the enrolled infants. A lower proportion of infants developed BPD in the LISA + SNIPPV group compared to the InSurE + CPAP group [10 (31.25%) vs. 21 (36.84%), P > 0.05]; however, there was no statistically significant difference. The number needed to treat (NNT) with LISA + SNIPPV to prevent BPD development is 18. The mortality rate was not significant between our study arms [1 (3.13%) vs 2 (3.51%), P > 0.05]. There were no statistically significant differences in the durations (days) of MV [(12.18 ± 13.89) vs. (11.35 ± 11.61), P > 0.05], oxygen therapy [(35.03 ± 19.13) vs. (39.75 ± 17.91), P > 0.05] and re-intubation rates [(0.19 ± 0.40) vs. (0.21 ± 0.45), P > 0.05] between the two study groups. In terms of complications, the incidence of patent ductus arteriosus (PDA) [24 (75.00%) vs. 27 (47.37%), P < 0.05] was higher and a lower rate of disturbed liver function [1 (3.23%) vs. 19 (33.33%), P < 0.05] were observed in the LISA + SNIPPV group. Acid-base imbalances were reportedly significantly higher in the InSurE group (P < 0.05). No significant differences in other complications were noted. In the interventional group, FiO2 requirements were significantly lower up until the 3rd week of treatment [FiO2 at day 0, (30.75 ± 4.78) vs. (34.66 ± 9.83), P < 0.05; FiO2 at day 21, (25.32 ± 3.74) vs. (29.11 ± 8.17), P < 0.05], as was RSS on days 2 [(0.77 ± 0.38) vs. (1.94 ± 0.75), P < 0.05] and 3 [(0.66 ± 0.33) vs. (1.89 ± 0.82), P < 0.05] after treatment. Additionally, infants in the standard group had a significantly prolonged hospital stay (days) [(45.97 ± 16.93) vs. (54.40 ± 16.26), P < 0.05]. The combination of LISA and SNIPPV for NRDS can potentially lower the rate of BPD, FiO2 demand and shorten the length of hospitalization.

Abstract
Non-invasive modes of respiratory support have been shown to be the preferable way of primary respiratory support of preterm infants with respiratory distress syndrome (RDS). The avoidance of invasive mechanical ventilation can be beneficial for preterm infants in reduction of morbidity and even mortality. However, it is well-established that some infants managed with non-invasive respiratory support from the outset have symptomatic RDS to a degree that warrants surfactant administration. Infants for whom non-invasive respiratory support ultimately fails are prone to adverse outcomes, occurring at a frequency on par with the group intubated primarily. This raises the question how to combine non-invasive respiratory support with surfactant therapy. Several methods of less or minimally invasive surfactant therapy have been developed to address the dilemma between avoidance of mechanical ventilation and administration of surfactant. This paper describes the different methods of less invasive surfactant application, reports the existing evidence from clinical studies, discusses the limitations of each of the methods and the open and future research questions.

Abstract
OBJECTIVE To describe the use of quality improvement methodology in transitioning from delivery of surfactant by INSURE (INtubation-SURfactant administration-Extubation) to video laryngoscope-assisted LISA (less-invasive surfactant administration) for infants with respiratory distress syndrome (RDS) receiving non-invasive ventilatory support. SETTING Two large neonatal intensive care units (NICUs) at Northwell Health (New Hyde Park, New York, USA). STUDY POPULATION Infants with RDS receiving continuous positive airway pressure in the NICU and eligible for surfactant administration. RESULTS LISA was initiated in our NICUs in January 2021, after extensive guideline development, education programmes, hands-on training and provider credentialing. Our Specific, Measurable, Achievable, Relevant and Timely aim was to deliver surfactant by LISA for 65% of total doses by 31 December 2021. This goal was achieved within 1 month of go-live. In total, 115 infants received at least one dose of surfactant during the year. Of those, 79 (69%) received it via LISA and 36 (31%) via INSURE. Two Plan-Do-Study-Act cycles contributed to improved adherence to guidelines on timely surfactant administration and both written and video documentation. CONCLUSIONS Safe and effective introduction of LISA with the use of video laryngoscopy is achievable with careful planning, clear clinical guidelines, adequate hands-on training and comprehensive safety and quality control.

Abstract
Bronchopulmonary dysplasia (BPD) is one of the most devastating morbidities of preterm infants. Antenatal factors like growth restriction and inflammation are risk factors for its development. Use of oxygen and positive pressure ventilation, which are often necessary to treat respiratory distress syndrome (RDS), increase the risk for development of BPD. Continuous positive airway pressure (CPAP) as primary respiratory support allows for avoidance of positive pressure ventilation in many cases but may lead to a delay of surfactant administration which is a proven therapy for RDS. Several alternative surfactant delivery strategies, including nebulization of surfactant, pharyngeal instillation of surfactant, delivery of surfactant via supraglottic airway device or surfactant delivery via a thin endotracheal catheter have been described which allow for the benefit of surfactant therapy while on CPAP. This review reports available data and discusses the existing evidence of their value in preventing BPD as well as further research directions.

Abstract
Background Minimally invasive surfactant therapy (MIST), a method of surfactant delivery via a thin catheter during spontaneous breathing, is an increasingly popular alternative to intubation and surfactant administration. Recently, purpose-built catheters for MIST received regulatory approval in Canada and became available for use. However, procedural success and user experience with such catheters have not been described. Methods This retrospective cohort study included neonates who received MIST using purpose-built catheters between January 1, 2021, and March 31, 2022. Two types of purpose-built catheters were used in this period - SurfCath™ and BLEScath™. Procedural success, number of attempts, and adverse events in neonates receiving MIST via the two catheters were compared using chi-square or Fisher's tests. User experience was described using an ease-of-use scale. Results Thirty-seven neonates met eligibility criteria; 22 received MIST via SurfCath™, whereas 15 received MIST via BLEScath™. Success rates were 91% in SurfCath™ and 93% in BLEScath™ (P> 0.994). Failed attempts were lower in SurfCath™ (23%) in comparison to BLEScath™ (33%), but the difference was not statistically significant (P=0.708). Among operators, 90% found SurfCath™ very easy/relatively easy to use compared to 43% of users reflecting the same degree of use with BLEScath™ (P=.021). There was no difference in adverse events. Conclusion This is the first study in Canada to report MIST with purpose-built catheters. Overall, the success rate was equally high with both catheters. Users subjectively reported higher ease of use with SurfCath™. Commercially available purpose-built catheters should facilitate universal adaptation of the MIST method.

Abstract
BACKGROUND Examine the real-world clinical impact of adopting less invasive surfactant administration (LISA) as the primary surfactant administration method in extremely preterm infants. METHODS Single-center pre-post cohort study conducted over a 4-year period comparing outcomes of spontaneously breathing inborn infants 24+0-28+6 weeks gestational age (GA) receiving surfactant via endotracheal tube (pre-cohort, n = 154) or LISA via thin catheter (post-cohort, n = 70). Primary outcome was need for invasive mechanical ventilation (IMV, ≥2 h) ≤72 h of age. Secondary outcomes were a composite of mortality, bronchopulmonary dysplasia, intraventricular hemorrhage ≥grade 3 or necrotizing enterocolitis, and its individual components. Groups were compared using propensity score methods, including covariates: GA, birth weight, sex, small for GA, SNAP II ≥20, premature rupture of membranes, maternal hypertension/diabetes, and C-section. RESULTS GA and birth weight were 27.1 (26, 28.1) weeks and 914 (230) g, and 27.1 (26.1, 28.1) weeks and 920 (236) g for pre- and post-cohorts, respectively. Pre-cohort had higher C-section rates, (67% vs. 51%, p = 0.03). After adjustment for covariates, LISA was associated with reduced IMV exposure [AOR (95% CI) 0.07 (0.04, 0.11)], lower odds of the composite clinical outcome [0.49 (0.33, 0.73)], and most of its individual components. CONCLUSION Real-world experience favors LISA as the primary method in extremely preterm infants with established spontaneous respiration. IMPACT Less invasive surfactant administration (LISA) is associated with a reduction in respiratory morbidity, but real-world data of routine use among extremely preterm infants are limited. LISA is associated with reduced frequency of exposure to and duration of IMV in both ≤72 h after birth and during hospital stay. LISA is associated with a reduction in mortality, and most other major morbidities including bronchopulmonary dysplasia, and interventricular hemorrhage. Data from a large North American center providing real-world clinical outcomes following LISA as the primary method of surfactant administration.

Abstract
OBJECTIVES Minimally Invasive Surfactant Treatment (MIST) is a common method for administering surfactant as a treatment for respiratory distress syndrome. However, tracheal catheter placement can be difficult to confirm. We assessed the presence of carbon dioxide (CO2) in tracheal and esophageal gas aspirated using CO2 detector. STUDY DESIGN Retrospective arm: 20 infants, MIST catheter placement was assessed with a CO2 detector in two techniques and confirmed with clinical response. Prospective arm-10 infants, aimed to check for CO2 presence in aspirated esophageal gas during routine nasogastric tube insertion. RESULTS Retrospective arm: All infants had positive capnography. One infant that had no clinical response to MIST was diagnosed with total anomalous pulmonary venous return. All 10 infants of the prospective arm had a Negative capnography (P < 0.001, Fisher's exact test). CONCLUSIONS Readily available CO2 detectors can distinguish between tracheal and esophageal placement of MIST catheters prior to MIST.

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.

Abstract
OBJECTIVE
To quantify the effect of early rescue surfactant administration techniques for preterm infants with respiratory distress syndrome (RDS) from a health care delivery system perspective.
METHODS
A cost-consequence model was developed based on previously published literature to compare the health economic impact of implementing early surfactant administration strategies vs standard surfactant administration via endotracheal intubation and mechanical ventilation (MV).
RESULTS
Early rescue surfactant treatment strategies are associated with a decrease in the number of patients requiring MV, cumulative MV days, and rate of neonatal complications. Total annual surfactant costs are higher than standard surfactant administration, but this is offset by savings in total hospital and complication costs.
CONCLUSIONS
This cost-consequence analysis suggests selective early rescue surfactant administration strategies are associated with a lower health care burden in premature infants with RDS.

Abstract
The provision of exogenous surfactant to premature infants with respiratory distress syndrome has revolutionized the way we care for these patients, significantly improving survival and decreasing morbidity. Currently, the Intubate-SURfactant-Extubate (INSURE) to non-invasive ventilation method remains the standard method for surfactant delivery in the United States. However, the INSURE method requires intubation via direct visualization with a laryngoscope and possible need for sedation. Both carry significant risk to the patients, prompting the development of less invasive ways of safely and efficaciously providing surfactant to newborn infants. The present article reviews and describes the benefits and limitations of several of these alternative methods, including Less Invasive Surfactant Administration (LISA), Minimally Invasive Surfactant Therapy (MIST), via aerosolization, laryngeal mask airway (LMA), and direct nasopharyngeal deposition, focusing on assessment of clinical benefits and the level/risk of invasiveness.

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
Noninvasive ventilation is frequently used in the treatment of infants with respiratory distress syndrome. This practice is often effective in higher gestational age neonates, but can be difficult in those with lower gestational ages as surfactant deficiency can be severe. While noninvasive ventilation avoids the negative effects of intubation and ventilator-induced lung injury, failure of this mode of support does occur with relative frequency and is primarily caused by the poorly compliant, surfactant-deficient lung. Because of the potential problems associated with laryngoscopy and intubation, neonatologists have developed various methods to deliver surfactant in minimally invasive ways with the aim of improving the success of noninvasive ventilation. Methods of minimally invasive surfactant administration include various thin catheter techniques, aerosolization/nebulization, and the use of a laryngeal mask airway/supraglottic airway device. The clinician should recognize that currently the only US Food and Drug Administration-approved device to deliver surfactant is an endotracheal tube and all methods reviewed here are considered off-label use. This review will focus primarily on surfactant administration through laryngeal or supraglottic airways, providing a review of the history of this technique, animal and human trials, and comparison with other minimally invasive techniques. In addition, this review provides a step-by-step instruction guide on how to perform this procedure, including a multimedia tutorial to facilitate learning.

Abstract
BACKGROUND AND OBJECTIVES Many preterm infants stabilized on continuous positive airway pressure (CPAP) at birth require mechanical ventilation (MV) during the first 72 hours of life, which is defined as CPAP failure. Our objective was to decrease CPAP failure in infants ≤29 weeks' gestational age (GA). METHODS A quality improvement bundle named OPTISURF was implemented for infants ≤29 weeks' GA admitted on CPAP, consisting of stepwise escalation of CPAP and less invasive surfactant administration guided by fractional inspired oxygen concentration ≥0.3. The CPAP failure rate was tracked by using control charts. We compared practice and outcomes of a pre-OPTISURF cohort (January 2017 to September 2018) to a post-OPTISURF cohort (October 2018 to December 2019). RESULTS Of the 216 infants ≤29 weeks' GA admitted to NICU on CPAP, 125 infants belonged to the pre-OPTISURF cohort (OSC) and 91 to the post-OSC. Compared with the pre-OSC, a higher proportion of infants in the post-OSC received CPAP 7 cm H2O within 4 hours of life (7% vs 32%; P < .01). The post-OSC also had lower rates of CPAP failure (54% vs 11%; P < .01), pneumothoraces (8% vs 1%; P < .03), need for MV (58% vs 31%; P < .01), and patent ductus arteriosus treatment (21% vs 9%; P = .02). Additionally, in a subgroup analysis, CPAP failure was lower in the post-OSC among infants 23 to 26 weeks (79% vs 27%; P < .01) and 27 to 29 weeks' GA (46% vs 3%; P < .01). CONCLUSIONS Implementation of a quality improvement bundle including CPAP optimization and less invasive surfactant administration decreased CPAP failure and need for MV in preterm infants.

Abstract
OBJECTIVE Surfactant delivery via a thin endotracheal catheter during spontaneous breathing; a technique called minimally invasive surfactant therapy (MIST) is an alternative to intubation and surfactant administration. Procedural details among different centers vary, with marked differences in the choice of catheter to instill surfactant. Studies report use of feeding catheters, multiaccess suction catheters, vascular catheters, and more recently custom-built catheters for this purpose. The impact of choice of catheter on procedural success and procedural adverse effects has not been reported. Our present study compares the procedural success and adverse effects of MIST using a semirigid vascular catheter (16G Angiocath-Hobart Method) versus a flexible multiaccess catheter (MAC). STUDY DESIGN This was a retrospective review of prospectively collected data at a tertiary care neonatal intensive care unit in Southwestern Ontario. All neonates who received surfactant via MIST between May 1, 2016 and September 30, 2020 were included in the study. Relevant baseline characteristics and data on procedural details (premedication, type of catheter, etc.) were collected. The procedural success, number of attempts, and adverse effects between neonates who received MIST via MAC and 16G Angiocath was compared by using Chi-square test or Fisher's test as appropriate. A p-value of less that 0.05 was considered significant. RESULTS A total of 139 neonates received surfactant via MIST method during the study period. Moreover, 93 neonates received the surfactant via MAC, while 46 received it via Angiocath. The baseline demographic characteristics in the two group were similar. A higher proportion of neonates in Angiocath group received Atropine (100 vs. 76%, p = 0.002) and Fentanyl (98 vs. 36%, p < 0.001) than the MAC group.The procedural success was 91% in the Angiocath group and 89% in the MAC group (p > 0.99). Multiple attempts were needed in 24% of neonates in the Angiocath group and 37% in the MAC group (p = 0.158). More episodes of desaturations were noted in the Angiocath group (89%) than the MAC group (69%; p = 0.012). Other rates of common adverse effects were similar between the two groups. On exploratory analysis fentanyl use held significant association with less success, more desaturation, apneic episodes, and need of positive pressure ventilation /intubation. CONCLUSION The overall procedural success of MIST is similar in both catheter groups. The proportion of neonates requiring multiple attempts was lower with the Angiocath, though difference was not statistically significant. Desaturation episodes were seen more frequently in the Angiocath group, which was related to higher use of procedural sedation in this group. KEY POINTS · MIST is emerging as a less invasive method of surfactant delivery that has proven clinical benefits.. · Considerable, procedural variation is reported, particularly regarding choice of catheter.. · Our present study compares the procedural success and adverse effects of MIST using a semirigid vascular catheter (16G Angiocath-Hobart method) versus a flexible MAC.. · High and comparable procedural success was seen in both groups..

Abstract
OBJECTIVE The efficacy and safety of surfactant administration via thin catheter in preterm infants with neonatal respiratory distress syndrome (NRDS) was investigated. METHODS PubMed, Embase, Cochrane Library, and Web of Science databases were searched to identify randomized controlled trials (RCTs) that comparing thin catheter technique with intubation for surfactant delivery in preterm infants with NRDS. RESULTS Thirteen RCTs (1931 infants) were included in the meta-analysis. The use of thin catheter technique decreased the incidences of bronchopulmonary dysplasia (BPD), pneumothorax, and hemodynamically significant patent ductus arteriosus (hsPDA) (risk ratio [RR]: 0.59, 95% confidence interval [CI]: 0.46-0.75, p < .0001; RR: 0.60, 95% CI: 0.39-0.93, p = .02 and RR: 0.88, 95% CI: 0.78-1.00, p = .04, respectively). In addition, infants in the intervention group required less mechanical ventilation within 72 h of life or during hospitalization (RR: 0.60, 95% CI: 0.48-0.75, p < .00001 and RR: 0.64, 95% CI: 0.49-0.82, p = .0005, respectively) compared with infants in the control group. However, the rate of surfactant reflux was higher in the intervention group than that in the control group (RR: 2.12, 95% CI: 1.37-3.29, p = .0008). There were no significant differences in mortality and other outcomes between the two groups. CONCLUSION The administration of surfactant via thin catheter could lower the requirement for mechanical ventilation, and decrease the incidence of BPD, pneumothorax, and hsPDA.

Abstract
BACKGROUND Non-invasive respiratory support is increasingly used for the management of respiratory dysfunction in preterm infants. This approach runs the risk of under-treating those with respiratory distress syndrome (RDS), for whom surfactant administration is of paramount importance. Several techniques of minimally invasive surfactant therapy have been described. This review focuses on surfactant administration to spontaneously breathing infants via a thin catheter briefly inserted into the trachea. OBJECTIVES Primary objectives In non-intubated preterm infants with established RDS or at risk of developing RDS to compare surfactant administration via thin catheter with: 1. intubation and surfactant administration through an endotracheal tube (ETT); or 2. continuation of non-invasive respiratory support without surfactant administration or intubation. Secondary objective 1. To compare different methods of surfactant administration via thin catheter Planned subgroup analyses included gestational age, timing of intervention, and use of sedating pre-medication during the intervention. SEARCH METHODS We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions(R); and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), on 30 September 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials. SELECTION CRITERIA We included randomised trials comparing surfactant administration via thin catheter (S-TC) with (1) surfactant administration through an ETT (S-ETT), or (2) continuation of non-invasive respiratory support without surfactant administration or intubation. We also included trials comparing different methods/strategies of surfactant administration via thin catheter. We included preterm infants (at < 37 weeks' gestation) with or at risk of RDS. DATA COLLECTION AND ANALYSIS Review authors independently assessed study quality and risk of bias and extracted data. Authors of all studies were contacted regarding study design and/or missing or unpublished data. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included 16 studies (18 publications; 2164 neonates) in this review. These studies compared surfactant administration via thin catheter with surfactant administration through an ETT with early extubation (Intubate, Surfactant, Extubate technique - InSurE) (12 studies) or with delayed extubation (2 studies), or with continuation of continuous positive airway pressure (CPAP) and rescue surfactant administration at pre-specified criteria (1 study), or compared different strategies of surfactant administration via thin catheter (1 study). Two trials reported neurosensory outcomes of of surviving participants at two years of age. Eight studies were of moderate certainty with low risk of bias, and eight studies were of lower certainty with unclear risk of bias. S-TC versus S-ETT in preterm infants with or at risk of RDS Meta-analyses of 14 studies in which S-TC was compared with S-ETT as a control demonstrated a significant decrease in risk of the composite outcome of death or bronchopulmonary dysplasia (BPD) at 36 weeks' postmenstrual age (risk ratio (RR) 0.59, 95% confidence interval (CI) 0.48 to 0.73; risk difference (RD) -0.11, 95% CI -0.15 to -0.07; number needed to treat for an additional beneficial outcome (NNTB) 9, 95% CI 7 to 16; 10 studies; 1324 infants; moderate-certainty evidence); the need for intubation within 72 hours (RR 0.63, 95% CI 0.54 to 0.74; RD -0.14, 95% CI -0.18 to -0.09; NNTB 8, 95% CI; 6 to 12; 12 studies, 1422 infants; moderate-certainty evidence); severe intraventricular haemorrhage (RR 0.63, 95% CI 0.42 to 0.96; RD -0.04, 95% CI -0.08 to -0.00; NNTB 22, 95% CI 12 to 193; 5 studies, 857 infants; low-certainty evidence); death during first hospitalisation (RR 0.63, 95% CI 0.47 to 0.84; RD -0.02, 95% CI -0.10 to 0.06; NNTB 20, 95% CI 12 to 58; 11 studies, 1424 infants; low-certainty evidence); and BPD among survivors (RR 0.57, 95% CI 0.45 to 0.74; RD -0.08, 95% CI -0.11 to -0.04; NNTB 13, 95% CI 9 to 24; 11 studies, 1567 infants; moderate-certainty evidence). There was no significant difference in risk of air leak requiring drainage (RR 0.58, 95% CI 0.33 to 1.02; RD -0.03, 95% CI -0.05 to 0.00; 6 studies, 1036 infants; low-certainty evidence). None of the studies reported on the outcome of death or survival with neurosensory disability. Only one trial compared surfactant delivery via thin catheter with continuation of CPAP, and one trial compared different strategies of surfactant delivery via thin catheter, precluding meta-analysis. AUTHORS' CONCLUSIONS Administration of surfactant via thin catheter compared with administration via an ETT is associated with reduced risk of death or BPD, less intubation in the first 72 hours, and reduced incidence of major complications and in-hospital mortality. This procedure had a similar rate of adverse effects as surfactant administration through an ETT. Data suggest that treatment with surfactant via thin catheter may be preferable to surfactant therapy by ETT. Further well-designed studies of adequate size and power, as well as ongoing studies, will help confirm and refine these findings, clarify whether surfactant therapy via thin tracheal catheter provides benefits over continuation of non-invasive respiratory support without surfactant, address uncertainties within important subgroups, and clarify the role of sedation.

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.

Abstract
BACKGROUND Less invasive surfactant administration (LISA) seems to have a good application prospect both in experimental models and patients with respiratory distress syndrome (RDS). Data regarding the effect of LISA procedure on RDS are conflicting. METHODS A search was conducted by two investigators involved in this research in PubMed, Embase, and Cochrane databases for studies in English and in Wanfang, VIP, and Cnki databases for Chinese studies (all last launched on December 18, 2018). Odds ratio and weighted mean difference were calculated using a random-effects or fixed-effects model, depending on the data type and heterogeneity of the included studies. RESULTS The comparison of effectiveness on RDS: (1) with respect to mechanical ventilation (<72 hours) and mechanical ventilation (all time periods). Data showed significant differences between LISA/control groups. (2) With respect to days of mechanical ventilation, data showed no significant differences between LISA/control groups. (3) With respect to bronchopulmonary dysplasia, the analysis showed that there was significant difference between LISA group and control group. (4) Regarding days of supplementary oxygen therapy and hospital stay, no significant differences were found. The comparison of possible complications of RDS: (1) data for mortality, pneumothorax and pulmonary hemorrhage showed no differences in the two groups. (2) Data for retinopathy of preterm comparison showed significant difference between the two groups. (3) Regarding intraventricular hemorrhage/periventricular leukomalacia, significant differences were found between the two groups. CONCLUSION Based on the above evidences, LISA is an effective and safe treatment for preterm infants with RDS.

Abstract
Background/Aims: Nasal continuous positive airway pressure (nCPAP) was recommended as the initial respiratory support for spontaneous breathing in infants with very low birth weight and neonatal respiratory distress syndrome (NRDS). Less invasive surfactant administration (LISA) and minimally invasive surfactant therapy (MIST) have been reported to reduce the incidence of bronchopulmonary dysplasia (BPD). This study aimed to explore the applicability of minimally invasive surfactant administration (MISA) in China. Materials and Methods: MISA was a randomized controlled study conducted at eight level III neonatal intensive care units (NICUs) in China. Spontaneously breathing infants born at 25+0 to 31+6 weeks' gestation who progressively developed respiratory distress during the first 6 h after birth were randomly assigned to receive MISA or endotracheal intubation surfactant administration (EISA). The primary outcome was the difference in the morbidity of BPD between two groups of infants with MISA and EISA at 36 weeks corrected gestational age. Results: Demographic and clinical characteristics of the 151 infants in the MISA group were similar to the 147 infants in the EISA group. The comparison showed no clear benefits in the MISA group in the incidence of BPD, while infants from the EISA group had higher rates of patent ductus arteriosus (PDA) (60.5 vs. 41.1%, p = 0.001). The duration of surfactant infusion and the total time of surfactant administration in the MISA group were significantly longer than in the EISA group. A slightly increased heart rate was noted 1 h post surfactant administration in the EISA group. In subgroup analysis, the comparison of 51 smaller (<30 weeks) preterm infants, named MISAs (n = 31) and EISAs (n = 20), showed a significant reduction of BPD (29.0 vs. 70.0%, p = 0.004) and PDA (29.0 vs. 65.0%, p = 0.011). In the subgroup analysis of blood gas, arterial oxygen saturation (SaO2) value at 1 and 12 h and partial pressure of arterial oxygen (PaO2) at 12 h were all higher in the EISA group compared to the MISA group. Conclusion: MISA had no clear benefit on the incidence of BPD, but it was related to a reduction in PDA. It is an appropriate therapy for spontaneous breathing in infants with extremely low birth weight and NRDS.

Kaniewska U, Gulczyńska E. The influence of the technique of surfactant administration (LISA vs INSURE) on the outcomes of respiratory distress syndrome treatment in preterm infants. DEVELOPMENTAL PERIOD MEDICINE 2019.

Abstract
OBJECTIVE Intratracheal administration of exogenous surfactant is a well-established therapy for respiratory distress syndrome in preterm infants. The two preferred methods for respiratory support in neonates that contribute to limiting the risk of lung damage associated with mechanical ventilation include nCPAP and non-invasive ventilation. The increasing popularity of surfactant administration techniques is due to the fact they reduce the time of mechanical ventilation until this medication is administered. In some cases a short period of mechanical ventilation follows (INSURE: INtubation-SURfactant-Extubation). There are also methods that make it possible to completely avoid intubation and help maintain spontaneous breathing during surfactant administration (LISA: Less Invasive Surfactant Administration, MIST: Minimal Invasive Surfactant Therapy). Aim: To analyze treatment outcomes in preterm infants who suffer from respiratory distress syndrome and require exogenous surfactant administration depending on the technique used: LISA vs INSURE. PATIENTS AND METHODS Material and methods: The present retrospective analysis included 129 infants born at a gestational age of between 24 and 33 weeks who were hospitalized in the Neonatology Department in the years 2014-2016, were administered surfactant and remained on non-invasive ventilation. All the subjects received only proractant alfa. Both study groups: LISA (n=83) and INSURE (n=46) were analyzed in terms of respiratory distress treatment outcomes and the presence of complications of prematurity. RESULTS Results: There were no significant differences in patient characteristics between the two study groups (LISA vs INSURE: mean birth body weight was 1210 g vs 1275 g, respectively; mean gestational age at birth was 30 weeks vs 29 6/7 weeks, respectively). The comparison of respiratory support method and FiO2 concentration within the first 72 hours after surfactant administration showed no significant differences between the groups. Similarly, respiratory outcomes did not significantly differ between the LISA and INSURE groups and were: the need for intubation ⎼ 42.2% vs 32.6%, p=0.201, duration of mechanical ventilation - median days 0 vs 0, p=0.377, duration of nCPAP - median days 5 vs 5, p=0.379, duration of oxygen supplementation - median days 1 vs 1, p=0.555, and the incidence of bronchopulmonary dysplasia - 28.9% vs 23.9%, p=0.506. Also, the incidence of complications was similar in both study groups. CONCLUSION Conclusions: Our retrospective analysis of preliminary outcomes of surfactant administration involving the use of the LISA technique showed no statistically significant differences as compared with the INSURE method. The randomized, prospective study that is currently being conducted at our Neonatology Department and includes biochemical markers of lung damage, will bring more objective data on the safety and effectiveness of both surfactant administration techniques (LISA vs INSURE).

Abstract
BACKGROUND The majority of extremely low gestational age neonates undergo intubation for surfactant therapy. Less invasive surfactant administration (LISA) uses a thin catheter inserted into the trachea to deliver the surfactant. During the procedure, the infant is breathing spontaneously while supported with continuous positive airway pressure. Although LISA is widely adapted in Europe and Australia, the rate of LISA use in the United States is unknown. STUDY DESIGN The aim of this study is to evaluate the use of LISA in the US. A web-based survey was distributed via SurveyMonkey to 2550 neonatologists from AAP's SoNPM mailing list. RESULTS Of the 472 neonatologists who answered the survey, 15% used LISA either as a part of routine care (8%) or as part of research (7%). CONCLUSION Unlike several regions of Europe, LISA is not widely used in the US. Future studies should address ambiguities regarding infant selection, procedure training and "roadblocks" to its broader application.

Abstract
Exogenous surfactant replacement is the most effective evidence-based therapy for respiratory distress syndrome in preterm infants. The mode of administration has evolved in the last decade towards less invasive techniques that aim to effectively provide an adequate dose of surfactant, while allowing spontaneous respiration to continue, and with the support of continuous positive airway pressure. Surfactant delivery via aerosolisation, pharyngeal instillation, and laryngeal mask are being actively pursued in research, but have not yet been adopted to any significant degree in clinical practice. Surfactant administration via thin catheter, on the other hand, is becoming more widely used in neonatal intensive care units worldwide and is now an acknowledged alternative to the standard mode of surfactant delivery. Different devices, including nasogastric tubes, vascular catheters, and purpose-built surfactant instillation catheters are used. We present here a contemporary review of surfactant administration via thin catheter, in a practical guide format that reflects the individual and collective scientific opinions of the clinicians who participated in formulating the guide.

Abstract
Background Surfactant delivery via a thin endotracheal catheter during spontaneous breathing, a technique called minimally invasive surfactant therapy (MIST), is an alternative to intubation and surfactant administration. There is paucity of data regarding the administration of high-volume surfactant using this technique. Methods We conducted a retrospective cohort study to review the safety, efficacy, and procedural details pertaining to the delivery of 5 mL/kg of BLES® via MIST approach. In 2016, our centre initiated a practice change allowing the use of MIST as an alternative method of surfactant delivery in infants born at ≥28 weeks and/or with a birth weight ≥ 1,000 g with respiratory distress syndrome. In this study, we identified all neonates who received surfactant via MIST between May 1, 2016 and July 30, 2018 and collected relevant procedural data. Results Since this practice change, MIST technique was attempted in 43 neonates with successful instillation of surfactant in 41 (95.3%) of the neonates. Intubation and positive pressure ventilation was avoided in 35 neonates (85.3%). No serious adverse effect was noted. Conclusions Our study reports successful use of higher volume surfactant via MIST. This should encourage other similar centres to consider this technique, in order to avoid unnecessary intubation and positive pressure ventilation.

Abstract
INTRODUCTION Most infants born before 30 weeks gestational age (GA) develop respiratory distress syndrome soon after birth. Methods of surfactant administration that avoid ventilation have been recently introduced. The aim of this study was to evaluate the impact of implementing a new procedure of less invasive surfactant administration (LISA) and determine whether it is associated with an improvement in respiratory outcome. METHODS This single center cohort quality improvement study analyzed preterm infants born before 30 weeks GA between May 2010 and April 2016. Changes in health care practices and respiratory outcomes following the implementation of a LISA, i.e. the administration of surfactant through a thin catheter, were analyzed using quality control charts. Then, the effect of LISA on respiratory outcome was assessed by propensity score matching and logistic regression weighted by the inverse of the propensity score. RESULTS During the study period, 379 infants were included. Of those that were not intubated at ten minutes of life, 129 received surfactant and were ventilated for one hour or more (InVent), 127 received LISA, five received surfactant with tracheal mechanical ventilation for less than one hour (InSurE), and 55 were only treated with nasal continuous positive pressure during the first hour of neonatal care (nCPAP). Quality-chart analysis revealed rapid implementation of the method with a concomitant decrease in required ventilation. LISA was associated with fewer tracheal ventilation days and a lower incidence of supplemental oxygen on day 28. When controlling for the propensity to be exposed or not to LISA, this procedure was not associated with a lower risk of death or bronchopulmonary dysplasia (BPD) at 36 weeks postmenstrual age. CONCLUSION In this study, the successful implementation of the new method was associated with lower rates of mechanical ventilation, but without a significant reduction of grade I/II/III BPD or death.

Treatment and outcome data of very low birth weight infants treated with less invasive surfactant administration in comparison to intubation and mechanical ventilation in the clinical setting of a cross-sectional observational multicenter study. Eur J Pediatr 2018; 177:1207-1217.

Abstract
UNLABELLED The aim of this study was to contribute further to existing randomized controlled trials and meta-analyses showing advantages in the outcome of less invasive surfactant administration (LISA)-treated infants and add new aspects concerning treatment and outcome data collected in the routine clinical setting. Four hundred seven very low birth weight infants who received surfactant via either LISA or intubation methods were enrolled in the observational cross-sectional multicenter study. To compare infants in terms of surfactant administration, we used an exact matching procedure (the same gestational age, severe perinatal depression (pH < 7.10), birth weight < 10th percentile, antenatal steroid treatment, and the same gender). To check for robustness, we performed repeated matching. LISA-treated infants required significantly less mechanical ventilation during hospital stay (p < 0.001) and days with supplemental oxygen (p = 0.03). Analgesics and sedatives were used less often during the stay (p < 0.001). Infants treated with LISA had significantly lower rates of bronchopulmonary dysplasia (p = 0.003). LISA failure infants were identified as more likely to be small for gestational age and more immature. CONCLUSION Our study complements former results with advantages for LISA-treated infants in mechanical ventilation and bronchopulmonary dysplasia in the clinical routine. TRIAL REGISTRATION DRKS00004589 What is Known: • According to existing literature, LISA-treated infants seem to have some favors in terms of treatment and outcome data. Observational studies in routine clinical setting are missing. What is New: • Data of 407 VLBW infants collected in routine clinical setting showed that LISA-treated infants needed less mechanical ventilation and fewer days with supplemental oxygen and less analgesics and sedatives. A reduced risk of BPD could be showed. SGA infants seem to have higher risks of LISA failure.

Abstract
Surfactant treatment of neonatal respiratory distress syndrome (RDS) was introduced in Europe during the 1990s. Meta-analyses have indicated that using less invasive surfactant administration techniques on preterm neonates receiving continuous positive airway pressure (CPAP) results in improved survival rates without bronchopulmonary dysplasia. Surfactant should be administered early and ventilator settings adapted to changing oxygen requirements and lung mechanics. Side effects including initial bradycardia, oxygen desaturation, tube obstruction and isolated cases of pulmonary haemorrhage have been reported. CONCLUSION Less invasive surfactant therapy improves pulmonary outcomes in preterm neonates with RDS and should ideally be administered in combination with CPAP.

Abstract
BACKGROUND Most preterm infants born at 29-32 weeks gestation now avoid intubation in early life, and thus lack the usual conduit through which exogenous surfactant is given if needed. OBJECTIVE The aim of this work was to examine whether a technique of minimally invasive surfactant therapy used selectively at 29-32 weeks gestation would improve outcomes. METHODS We studied the impact of selective administration of surfactant (poractant alfa 100-200 mg/kg) by thin catheter in infants with respiratory distress syndrome on continuous positive airway pressure (CPAP). The threshold for consideration of treatment was CPAP ≥7 cm H2O and FiO2 ≥0.35 prior to 24 h of life. In-hospital outcomes were compared before and after introducing minimally invasive surfactant therapy (epochs 1 and 2, respectively). RESULTS During epoch 2, of 266 infants commencing CPAP, 51 (19%) reached the treatment threshold. Thirty-seven infants received surfactant via thin catheter, and CPAP failure was avoided in 34 of these (92%). For the overall cohort of infants at 29-32 weeks gestation, after the introduction of minimally invasive surfactant therapy, there were reductions in CPAP failure (epoch 1: 14%, epoch 2: 7.2%) and average days of intubation, with equivalent surfactant use and days of respiratory support (intubation + CPAP). Pneumothorax was substantially reduced (from 8.0 to 2.4%). These findings were mirrored within the subgroups reaching the severity threshold in each epoch. The incidence of bronchopulmonary dysplasia was low in both epochs. CONCLUSIONS Selective use of minimally invasive surfactant therapy at 29-32 weeks gestation permits a primary CPAP strategy to be pursued with a high rate of success, and a low risk of pneumothorax.

Abstract
To date, preterm infants with respiratory distress syndrome (RDS) after birth have been managed with a combination of endotracheal intubation, surfactant instillation, and mechanical ventilation. It is now recognized that noninvasive ventilation (NIV) such as nasal continuous positive airway pressure (CPAP) in preterm infants is a reasonable alternative to elective intubation after birth. Recently, a meta-analysis of large controlled trials comparing conventional methods and nasal CPAP suggested that CPAP decreased the risk of the combined outcome of bronchopulmonary dysplasia or death. Since then, the use of NIV as primary therapy for preterm infants has increased, but when and how to give exogenous surfactant remains unclear. Overcoming this problem, minimally invasive surfactant therapy (MIST) allows spontaneously breathing neonates to remain on CPAP in the first week after birth. MIST has included administration of exogenous surfactant by intrapharyngeal instillation, nebulization, a laryngeal mask, and a thin catheter. In recent clinical trials, surfactant delivery via a thin catheter was found to reduce the need for subsequent endotracheal intubation and mechanical ventilation, and improves short-term respiratory outcomes. There is also growing evidence for MIST as an alternative to the INSURE (intubation-surfactant-extubation) procedure in spontaneously breathing preterm infants with RDS. In conclusion, MIST is gentle, safe, feasible, and effective in preterm infants, and is widely used for surfactant administration with noninvasive respiratory support by neonatologists. However, further studies are needed to resolve uncertainties in the MIST method, including infant selection, optimal surfactant dosage and administration method, and need for sedation.

Abstract
To systematically review the clinical outcomes of surfactant administration via a thin endotracheal catheter during spontaneous breathing compared with conventional administration involving tracheal intubation, mechanical ventilation (MV), and tracheal extubation, in preterm infants. PubMed, EMBASE, and the Cochrane Library were searched to identify relevant clinical trials. Data were analyzed using the Cochrane Collaboration methods. Primary outcome measures included the incidence of MV and bronchopulmonary dysplasia (BPD). Finally, four RCTs, two prospective cohort trials, and six historical controlled trials involving 5,261 preterm infants were analyzed. In RCTs, surfactant administration though a thin catheter reduced the incidence of MV (risk ratio [RR]: 0.74; 95% confidence interval [CI]: 0.66, 0.81) in 72 hr and BPD (RR: 0.69, 95%CI: 0.50, 0.97) compared with conventional administration and in non-RCTs, there was also significant reduction in the incidence of MV (RR: 0.55, 95%CI: 0.45, 0.68) and BPD (RR: 0.70, 95%CI: 0.60, 0.82) in favor of the thin catheter group. There were no significant differences between the two procedures in terms of short-term pulmonary complications, intracranial pathology, necrotizing enterocolitis, retinopathy of prematurity, and mortality. Thus, surfactant administration via a thin endotracheal catheter to preterm infants has promising benefits, including reducing the incidences of MV and BPD, while providing comparable breathing support to conventional administration in MV.

Abstract
OBJECTIVE To assess the outcome of a modified method of Minimally Invasive Surfactant Therapy (MIST) therapy where an orogastric tube was used for tracheal catherization to deliver surfactant in preterm newborns less than 34 wk of gestation with respiratory distress syndrome (RDS). METHODS A single centre, prospective observational study was conducted to enroll eligible inborn preterm neonates with gestation age more than 24 wk but less than 34 wk and suffering from RDS to receive surfactant using MIST. Results were compared with a historical cohort of preterms who received surfactant with InSurE (Intubate, Surfactant, Extubate) technique. RESULTS Sixty four cases in the modified MIST group were compared with a historic cohort of 68 cases in the InSurE group. There were no differences in the requirement of intubation and mechanical ventilation (MV) in the first 72 h but the duration of MV and continuous positive airway pressure (CPAP) were significantly less in modified MIST group. Other neonatal morbidities and mortality rates were similar in either of the groups. CONCLUSIONS The modified MIST technique is an effective method for the treatment of RDS in preterms with better clinical efficacy and comparable outcomes than the more invasive InSurE procedure and deserves further evaluation.

[PMID: 28029185 DOI: 10.1111/apa.13732] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2016] [Revised: 12/15/2016] [Accepted: 12/22/2016] [Indexed: 11/30/2022]
Abstract
AIM This Norwegian study explored whether administering surfactant without intubation (SWI) delayed the need for early mechanical ventilation and reduced respiratory and nonrespiratory complications in infants born before 32 weeks of gestational age. METHODS We compared 262 infants admitted to a level-three neonatal intensive care unit: 134 born before the introduction of SWI on 1 December 2011 were in the control group and 128 infants born after this date were in the study group. RESULTS The proportion of infants treated with surfactant did not differ between the groups, but mechanical ventilation before 72 hours of life was lower in the study group than the control group, with an odds ratio (OR) of 0.58 and a 95% confidence interval (CI) of 0.35-0.96. Fewer study group infants needed supplemental oxygen at 28 days of life. One study infant and nine control infants had intraventricular haemorrhage grades 3-4 and, or, cystic periventricular leukomalacia (OR 0.10, 95% CI 0.01-0.83). These results were strengthened in analyses restricted to surfactant-treated infants and the proportion needing supplemental oxygen at 36 weeks was reduced. CONCLUSION Surfactant without intubation reduced the need for early mechanical ventilation and major brain injuries in infants born at <32 weeks of gestation.

Abstract
AIM Less invasive surfactant administration (LISA), namely surfactant instillation through a thin catheter in the trachea during spontaneous breathing, is increasingly used for premature infants. We surveyed the use of this technique in the Nordic countries in autumn 2015. METHODS A link to a web-based survey of surfactant administration methods was emailed to the directors of all neonatal units in the Nordic Region, apart from Finland, where only the five university-based departments were invited. RESULTS Of the 73 units (85%) who responded, 23 (32%) said that they used LISA. The country rates were Iceland 100%, Norway 82%, Finland 60%, Denmark, including Faroe Island and Greenland, 11% and Sweden 9%. LISA was used in 62% of level three units, but only 14% of level two units and most commonly in babies with a gestational age of at least 26 weeks. Premedication was always or sometimes used by 78%. The main reasons for not using LISA were lack of familiarity with the technique (61%), no perceived benefit over other methods (22%) and concerns about patient discomfort (26%). CONCLUSION Less invasive surfactant administration was used in 32% of Nordic neonatal units, most commonly in level three units. Premedication was used more often than previously reported.

Abstract
UNLABELLED Less invasive surfactant administration or minimally invasive surfactant therapy (LISA/MIST) has been proposed for the administration of surfactant in preterm infants without intubation. The aim of our survey was to assess the rate of utilization, premedication as well as technique and equipment used for LISA/MIST. Furthermore, attitudes and experiences in regard to indications, side effects, and efficacy should be assessed. An online-based survey was sent to 324 neonatologists from different centers within 37 European countries between December 2015 and March 2016. Of those 165 who responded (response rate 51%), 86 (52%) were using LISA/MIST. It is regarded the standard procedure for surfactant administration by 41%, with a wide variation in personal views on patient selection in terms of indication, appropriate gestational and postnatal age. Policies concerning premedication, devices, and technique of LISA/MIST differed widely. Side effects like surfactant reflux, bradycardia, and hypoxia were observed by 77% of neonatologists. Of neonatologists inexperienced in LISA/MIST, 89% would consider utilizing it in the future. Perceived efficacy of LISA/MIST was high (52%) to medium (33%). CONCLUSION The use of LISA/MIST within Europe is widespread. There is a wide variation concerning all aspects of LISA in daily clinical routine and different views on when and how LISA should be performed. What is Known: • Noninvasive surfactant administration has been the subject of randomized controlled trials and has found its way into clinical routine. What is New: • Noninvasive surfactant administration techniques are widely applied in European neonatal units. • There is a wide variety of equipment used and techniques applied for less invasive surfactant delivery as well as different views on the indications and perceived efficacy of this intervention.

Abstract
Respiratory distress syndrome (RDS) caused by surfactant deficiency is major cause for neonatal mortality and short- and long-term morbidity of preterm infants. Continuous positive airway pressure and other modes of noninvasive respiratory support and intubation and positive pressure ventilation with surfactant therapy are efficient therapies for RDS. Because continuous positive airway pressure can fail in severe surfactant deficiency, and because traditional surfactant therapy requires intubation and positive pressure ventilation, this entails a risk of lung injury. Several strategies to combine noninvasive respiratory therapy with minimally invasive surfactant therapy have been described. Available data suggest that those strategies may improve outcome of premature infants with RDS.

Abstract
During recent decades, non-invasive respiratory support has become popular for treating neonates with respiratory failure. Several prospective randomized controlled trials have been performed to compare use of continuous positive airway pressure (CPAP) as primary respiratory support in preterm infants with respiratory distress syndrome (RDS) to endotracheal intubation, mechanical ventilation and surfactant therapy. Systematic reviews of these studies suggest that routine CPAP at delivery is efficacious in decreasing bronchopulmonary dysplasia (BPD), death, or both. This led to the recommendation to consider CPAP to avoid endotracheal intubation. As surfactant therapy is known to reduce BPD and death, several ways to combine CPAP with surfactant have been described. With the increasing use of CPAP immediately after birth, the early use of caffeine to stimulate respiration has become a point of discussion. This review focuses on different modes of surfactant application during CPAP and on the early use of caffeine as ancillary therapies to enhance CPAP success.

Abstract
There is a growing body of evidence over the last years suggesting continuous positive airway pressure (CPAP) ventilation being the first choice of ventilatory support in newborns with extremely low gestational age, and early rescue surfactant treatment being as effective as prophylactic therapy. The Intubation Surfactant Extubation procedure is discussed as an alternative procedure that may have the potential to combine the positive effects of surfactant and early CPAP. A further mode of surfactant administration, administration via a thin endotracheal catheter during spontaneous breathing with CPAP, has recently come into clinical use. This less invasive surfactant administration technique shows some short-term benefits but still cannot be recommended for general use in this vulnerable population. Long-term follow-up studies are needed to allow new recommendations on surfactant therapy in this high-risk population.

Abstract
CONTEXT Surfactant is the principle treatment of respiratory distress syndrome, but the ideal method of its administration remains controversial. The intubation, surfactant administration and extubation (InSurE) method is proven to work but is invasive. The objective of this systematic review is to evaluate the efficacy and safety of the modalities of surfactant administration. METHODS We searched MEDLINE, EMBASE and CENTRAL (inception to December 2015) for randomized trials comparing new modalities with InSurE method. The primary outcome was mortality and development of bronchopulmonary dysplasia (BPD). RESULTS We screened 1837 citations and identified five unique trials were included; all were of unclear risk of bias. Four trials (400 infants) compared endotracheal catheters with InSurE, and one trial (70 infants) compared laryngeal masks (LMA) with InSurE. There was no significant difference between using endotracheal catheters compared with InSurE regarding infant mortality (risk ratio 1.05, 95% CI 0.57-1.94, 4 trials, 400 patients, p 0.87, I(2) 0%) or BPD (risk ratio 0.73, 95% CI 0.43-1.21, 4 trials, 400 patients, p 0.22, I(2) 0%). Adverse events were under-reported. CONCLUSION The use of endotracheal catheters may provide comparable results to the InSurE method. There is limited evidence on the comparative efficacy of LMA.

Abstract
BACKGROUND There is no data available whether sedation should be given during minimally invasive surfactant therapy (MIST). OBJECTIVE To compare the level of comfort of preterm infants receiving sedation versus no sedation for MIST. METHODS A retrospective study of preterm infants receiving MIST was performed in Leiden University Medical Center in 2014. Sedation (propofol 1 mg/kg) was optional and left to the discretion of the caregiver. Standardized COMFORTneo scores were compared, and COMFORTneo <14 was considered comfortable. Basic characteristics and complications were noted. RESULTS In 38 infants receiving MIST, 23 received propofol and 15 were not sedated. Mean (SD) gestational age [29 (2) vs. 29 (3) weeks] and birth weight [1,312 (483) vs. 1,469 (588) g] were not different. Median (IQR) COMFORTneo was not different between the groups before [11 (9-15) vs. 10 (8-12)] and after MIST [10 (8-12) vs. 9 (8-10)], but lower in the sedated group during MIST [12 (9-17) vs. 20 (15-23)] with more often COMFORTneo <14 (56 vs. 11%). Duration of MIST [2 (2-4) vs. 3 (2-7) min] and occurrence of bradycardia (13 vs. 33%) and hypotension (21 vs. 18%) were not different. Although not significant, intubation occurred more often in the sedated group (during MIST: 9 vs. 0%, <24 h after MIST: 26 vs. 13%). During MIST, oxygen saturation <80% lasted longer in the sedated group [3 (2-4) vs. 1 (0-2) min], and nasal intermittent positive pressure ventilation was applied more (100 vs. 33%). CONCLUSIONS Preterm infants receiving MIST were more comfortable when sedation was given, but needed ventilation more often. A randomized controlled trial is warranted to test whether the benefit of sedation outweighs the risks of complications.

Abstract
Mechanical ventilation is an important potentially modifiable risk factor for the development of bronchopulmonary dysplasia. Effective use of noninvasive respiratory support reduces the risk of lung injury. Lung volume recruitment and avoidance of excessive tidal volume are key elements of lung-protective ventilation strategies. Avoidance of oxidative stress, less invasive methods of surfactant administration, and high-frequency ventilation are also important factors in lung injury prevention.

Abstract
BACKGROUND Less invasive surfactant administration (LISA) to spontaneously breathing preterm infants has been reported to reduce the duration of mechanical ventilation and the incidence of bronchopulmonary dysplasia (BPD) in previous study. The objective of this study was to explore the feasibility and potential benefits of LISA in early preterm infants on nasal continuous positive airway pressure (nCPAP) compared to conventional endotracheal instillation. METHODS All infants with respiratory distress born at 28-32 weeks' gestational age from January 2012 to December 2012 (n=90), who were eligible for exogenous pulmonary surfactant (PS) therapy were randomized to receive PS by intubation with an endotracheal tube (Intubation group, n=43), or by intubation using a catheter while on nCPAP (LISA group, n=47). Respiratory indices were recorded every 30 seconds during PS administration, and every 1 hour thereafter for the first day. The rate of mechanical ventilation (MV) in the first 72 hours, mean duration of both MV and nCPAP, mean duration of oxygen requirement and neonatal outcomes were recorded. RESULTS PS was successfully administered in 43 (100%) out of 43 babies using the conventional approach and in 46 (97%) out of 47 babies using LISA. The duration of both MV and nCPAP was significantly shorter in LISA group, when compared with intubation group. However, there were no significant differences in both the rate of MV in the first 72 hours and mean duration of oxygen requirement. There were also no differences in the mortality or in the incidence of bronchopulmonary dysplasia, intraventricular hemorrhage, retinopathy of prematurity and necrotizing enterocolitis, or in the duration of respiratory support. CONCLUSIONS LISA in spontaneously breathing infants on nCPAP is an alternative therapy for PS delivery, avoiding intubation with an endotracheal tube. The method is feasible and potentially effective, and deserves further clinical trials. TRIAL REGISTRATION Current Controlled Trials ChiCTR-ICR-15006001. Registered 20 February 2015.

Abstract
AIM Providing less invasive surfactant administration (LISA) to spontaneously breathing preterm infants has been reported to reduce mechanical ventilation and bronchopulmonary dysplasia (BPD) in randomised controlled trials. This large cohort study compared these outcome measures between LISA-treated infants and controls. METHODS Infants receiving LISA, who were born before 32 gestational weeks and enrolled in the German Neonatal Network, were matched to control infants by gestational age, umbilical cord pH, Apgar-score at 5 min, small for gestational age status, antenatal treatment with steroids, gender and highest supplemental oxygen during the first 12 h of life. Outcome data were compared with chi-square and Mann-Whitney U-tests and adjusted for multiple comparisons. RESULTS Between 2009 and 2012, 1103 infants were treated with LISA at 37 centres. LISA infants had lower rates of mechanical ventilation (41% versus 62%, p < 0.001), postnatal dexamethasone treatment (2.5% versus 7%, p < 0.001), BPD (12% versus 18%, p = 0.001) and BPD or death (14% versus 21%, p < 0.001) than the controls. CONCLUSION Surfactant treatment of spontaneously breathing infants was associated with lower rates of mechanical ventilation and BPD. Additional large-scale randomised controlled trials are needed to assess the possible long-term benefits of LISA.

Abstract
Objective: Currently, the method of early nasal continuous positive airway pressure (nCPAP) and selective administration of surfactant via an endotracheal tube is widely used in the treatment of respiratory distress syndrome (RDS) in premature infants. To prevent complications related to endotracheal intubation and even a brief period of mechanical ventilation, in this study, we compared the effectiveness of surfactant administration via a thin intratracheal catheter versus the current method using an endotracheal tube. Methods: Thirty eight preterm infants ≤34 weeks' gestation with birth weight of 1000–1800 g who were putted on nCPAP for RDS within the first hour of life, were randomly assigned to receive surfactant either via endotracheal tube (ET group) or via thin intratracheal catheter (CATH group). The primary outcomes were the need for mechanical ventilation and duration of oxygen therapy. Data were analyzed by independent t-test, Mann-Whitney U-test, and Chi-square test, using SPSS v. 21. Findings: There was no significant difference between groups regarding to need for mechanical ventilation during the first 72 h of birth (3 [15.8%] in ET group vs. 2 [10.5%] in CATH group; P = 0.99). Duration of oxygen therapy in CATH group was significantly lower than ET group (243.7 ± 74.3 h vs. 476.8 ± 106.8 h, respectively; P = 0.018). The incidence of adverse events during all times of surfactant administration was not statistically significant between groups (P = 0.14), but the number of infants who experienced adverse events during surfactant administration was significantly lower in CATH group than ET group (6 [31.6%] vs. 12 [63.2%], respectively; P = 0.049). All other outcomes, including duration of treatment with CPAP and mechanical ventilation, times of surfactant administration and the need for more than one dose of the drug, the rate of intraventricular hemorrhage, mortality and combined outcome of chronic lung disease or mortality were statistically similar between the groups Conclusion: Surfactant administration via thin intratracheal catheter in preterm infants receiving nCPAP for treatment of RDS has similar efficacy, feasibility and safety to its administration via endotracheal tube.

Abstract
Exogenous pulmonary surfactant, widely used in neonatal care, is one of the best-studied treatments in neonatology, and its introduction in the 1990s led to a significant improvement in neonatal outcomes in preterm infants, including a decrease in mortality. This chapter provides an overview of surfactant composition and function in health and disease and summarizes the evidence for its clinical use.

Abstract
Traditional treatment of respiratory distress syndrome in preterm infants consisted of early intubation, mechanical ventilation and intra-tracheal administration of exogenous surfactant. Recently, non-invasive ventilation, which has shown some advantages in short- and long-term outcomes, has gained popularity for the initial management of respiratory insufficiency in preterm infants. However, non-invasive ventilation from the outset poses difficulties in relation to administration of exogenous surfactant. The customary INSURE technique requires tracheal intubation, surfactant administration, and rapid extubation, but the latter is not always possible. As a more elegant approach, several minimally invasive techniques of delivering surfactant have been developed for babies spontaneously breathing on CPAP. The most extensively studied have been those in which the trachea is briefly catheterized with a nasogastric tube or vascular catheter, and exogenous surfactant is administered. Although results seem promising they are not yet conclusive, and further studies will be needed to answer a number of outstanding questions.

Abstract
Background It is now recognized that preterm infants ≤28 weeks gestation can be effectively supported from the outset with nasal continuous positive airway pressure. However, this form of respiratory therapy may fail to adequately support those infants with significant surfactant deficiency, with the result that intubation and delayed surfactant therapy are then required. Infants following this path are known to have a higher risk of adverse outcomes, including death, bronchopulmonary dysplasia and other morbidities. In an effort to circumvent this problem, techniques of minimally-invasive surfactant therapy have been developed, in which exogenous surfactant is administered to a spontaneously breathing infant who can then remain on continuous positive airway pressure. A method of surfactant delivery using a semi-rigid surfactant instillation catheter briefly passed into the trachea (the “Hobart method”) has been shown to be feasible and potentially effective, and now requires evaluation in a randomised controlled trial. Methods/design This is a multicentre, randomised, masked, controlled trial in preterm infants 25–28 weeks gestation. Infants are eligible if managed on continuous positive airway pressure without prior intubation, and requiring FiO2 ≥ 0.30 at an age ≤6 hours. Randomisation will be to receive exogenous surfactant (200 mg/kg poractant alfa) via the Hobart method, or sham treatment. Infants in both groups will thereafter remain on continuous positive airway pressure unless intubation criteria are reached (FiO2 ≥ 0.45, unremitting apnoea or persistent acidosis). Primary outcome is the composite of death or physiological bronchopulmonary dysplasia, with secondary outcomes including incidence of death; major neonatal morbidities; durations of all modes of respiratory support and hospitalisation; safety of the Hobart method; and outcome at 2 years. A total of 606 infants will be enrolled. The trial will be conducted in >30 centres worldwide, and is expected to be completed by end-2017. Discussion Minimally-invasive surfactant therapy has the potential to ease the burden of respiratory morbidity in preterm infants. The trial will provide definitive evidence on the effectiveness of this approach in the care of preterm infants born at 25–28 weeks gestation.

Abstract
Respiratory distress syndrome is pulmoner insufficiency caused by the lack of surfactant and the main reason of morbidity and mortality in preterm infants. Mothers at high risk of preterm birth should be transferred to perinatal centers with experience for respiratory distress syndrome and ante-natal steroids should be given before 35 weeks' of gestational age. Surfactant treatment should be applied to babies with or at high risk for respiratory distress syndrome. Prophylaxis should be given to infants of <26 weeks of gestational age and to infants requiring entubation in the delivery room. Nasal continuous positive airway pressure should be considered in infants with complete steroid treatment and without entubation need. Early surfactant may be given if entubation is performed during follow-up. Natural forms of surfactant should be preferred when needed. If the infant is stable, early extubation and non-invasive respiratory support should be considered. In this review, the recent studies' current data about surfactant treatment will be discussed.

Use of analgesic and sedative drugs in VLBW infants in German NICUs from 2003-2010. Eur J Pediatr 2013; 172:1633-9. [PMID: 23877637 DOI: 10.1007/s00431-013-2095-3] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2013] [Accepted: 07/04/2013] [Indexed: 10/26/2022]
Abstract
UNLABELLED Very low birth weight (VLBW) infants frequently receive analgesia and/or sedation for painful procedures and mechanical ventilation to avoid negative stress. Yet, concerns remain regarding potential adverse long-term effects of these drugs on VLBW infants' neurocognitive outcome. Recent studies have shown that less invasive surfactant application (LISA) and early nasal CPAP treatment reduce the need for mechanical ventilation and painful procedures. Therefore, these measures might also reduce the application of analgesic and/or sedative drugs in VLBW infants. To evaluate this hypothesis and to identify potential changes in analgesic treatment concepts in recent years, we retrospectively analyzed data on analgesia and sedation, respiratory support, and the method of surfactant application in VLBW infants enrolled in the German Neonatal Network (GNN) trial between 2003 and 2009 (period 1) and compared it with data from infants participating in GNN in 2010 (period 2). In both periods, about one third of all infants were treated with analgesic and/or sedative drugs using a wide variety of substances. The administration of novel drugs such as propofol, sufentanil, or intravenous paracetamol was higher in 2010 (6.7 vs. 12.2 %). Infants who were treated with CPAP only received significantly less analgesic/sedative medication than infants who were mechanically ventilated (12 vs. 65 %, p=<0.001). Similarly, infants treated with LISA received less analgesic or sedative drugs as compared to infants who received surfactant via endotracheal intubation (36 vs. 63 %, p=0.001). CONCLUSION Although both avoidances of mechanical ventilation and less invasive surfactant application are associated with reduced analgesic or sedative treatment, the percentage of VLBW infants who received analgesia and/or sedation remained unchanged in Germany in recent years.
