Predictors of successful trial off continuous positive airway pressure and high flow nasal cannula in preterm infants <30 weeks' gestation: A retrospective study. Pediatr Pulmonol 2022; 57:1000-1007.

Abstract
OBJECTIVES To identify the predictors of successful first trial off nasal continuous positive airway pressure (nCPAP). METHODS A retrospective cohort study of infants ≤29 weeks' gestation who required nCPAP for >24 h was conducted. Logistic regression was used to detect predictors for successful trial off nCPAP. Statistical analysis was performed using the SAS software. RESULTS A total of 727 infants were included in the analysis. Infants who were successful in their first trial off nCPAP (n = 313) were of higher gestational age (GA) and birth weight (BW), as well as a higher proportion of female infants, compared with those who were not successful (p < 0.01). When stratified by GA, a negative correlation was noted between GA and postmenstrual age at successful trial off nCPAP or high flow nasal cannula (HFNC) (r = 0.45, p < 0.01). Logistic regression analysis showed that GA (odds ratio [OR] 1.13, 95% confidence interval [CI] [1.03-1.24], p = 0.01) and percentage of time spent with an oxygen saturation over 89% in the 24 h preceding the trial off nCPAP (OR 1.08, 95% CI [1.05-1.11], p = 0.00) were independent predictors for successful trial off nCPAP. CONCLUSION Successful trial off nCPAP or HFNC in preterm infants is significantly associated with higher GA, BW, female gender, and the specific oxygen saturation histogram in the preceding 24-h period.

Abstract
BACKGROUND There is no consensus on how to wean infants from Nasal Continuous Positive Airway Pressure (NCPAP). We hypothesized that ceasing NCPAP abruptly would decrease the duration required, compared with a gradual wean. METHODS This retrospective chart review included preterm infants requiring NCPAP for over 48 hours. Cohort1 weaned NCPAP by cycling on and off, while cohort 2 ceased NCPAP abruptly. The primary outcome was total days on NCPAP. Secondary outcomes included rate of bronchopulmonary dysplasia, weight gain, duration of hospital stay, and compliance with the use of stability criteria. RESULTS 81 infants met inclusion criteria in cohort one, and 89 in cohort two. Median days on NCPAP were 17.0 and 11.0 days, respectively, not significant. There was no significant difference in secondary outcomes. CONCLUSIONS There was no significant association between the two NCPAP weaning protocols and the outcomes studied.

Abstract
BACKGROUND The aim of this study was to compare nasal masks (NM) with binasal prongs (NP) for applying nasal intermittent mandatory ventilation (NIMV) by assessing the duration of respiratory distress, rate of intubation, and nasal trauma in term infants with transient tachypnea of the newborn (TTN). METHODS Infants with a gestational age ≥37 weeks and birthweight ≥2,000 g who had NIMV administered for TTN were enrolled. We randomly allocated 80 neonates to the NM (n = 40) or NP (n = 40) group. Duration of respiratory distress was the primary outcome of this study. RESULTS There were no statistically significant differences between the groups for the duration of tachypnea and NIMV (P = 0.94 and P = 0.13, respectively). No significant differences were observed between the two groups in terms of duration of oxygen supplementation and length of hospitalization (P = 0.72 and P = 0.70, respectively). The incidence of any grade of trauma and moderate trauma (grade II) was significantly higher in the NP group than in the NM group (P = 0.004 and P = 0.04, respectively). The rate of NIMV failure and other complications, including pneumothorax, pneumonia and feeding intolerance, was not significantly different in the groups. CONCLUSIONS In term infants with TTN, delivering NIMV using NP in comparison to using NM appears to be similar with regard to the duration of respiratory distress and preventing intubation. However, the use of NP involves a greater risk of trauma than that of NM.

Weaning strategies for the withdrawal of non-invasive respiratory support applying continuous positive airway pressure in preterm infants: a systematic review and meta-analysis.

Abstract
BACKGROUND The optimal method to wean preterm infants from non-invasive respiratory support (NIVRS) with nasal continuous positive airway pressure (CPAP) or high-flow nasal cannula is still unclear, and methods used vary considerably between neonatal units. OBJECTIVE Perform a systematic review and meta-analysis to determine the most effective strategy for weaning preterm infants born before 37 weeks' gestation from NIVRS. METHOD EMBASE, MEDLINE, CINAHL, Google and Cochrane Central Register of Controlled Trials were searched for randomised controlled trials comparing different weaning strategies of NIVRS in infants born before 37 weeks' gestation. RESULTS Fifteen trials (1.547 infants) were included. With gradual pressure wean, the relative risk of successful weaning at the first attempt was 1.30 (95% CI 0.93 to 1.83), as compared with sudden discontinuation. Infants were weaned at a later postmenstrual age (PMA) (median difference (MD) 0.93 weeks (95% CI 0.19 to 1.67)). A stepdown strategy to nasal cannula resulted in an almost 3-week reduction in the PMA at successful weaning (MD -2.70 (95% CI -3.87 to -1.52)) but was associated with a significantly longer duration of oxygen supplementation (MD 7.80 days (95% CI 5.31 to 10.28)). A strategy using interval training had no clinical benefits. None of the strategies had any effect on the risk of chronic lung disease or the duration of hospital stay. CONCLUSION A strategy of gradual weaning of airway pressure might increase the chances of successful weaning. Stepdown strategy from CPAP to nasal cannula is a useful alternative resulting in an earlier weaning, but the focus should remain on continued weaning in order to avoid prolonged oxygen supplementation. Interval training should probably not be used.

Abstract
BACKGROUND Continuous positive airway pressure (CPAP) is widely used in preterm infants. Identification of readiness for weaning from CPAP can balance benefits with risks of CPAP exposure. We tested the hypothesis that preterm infants that successfully transition off CPAP have higher oxygen saturations prior to weaning compared with infants who fail weaning from CPAP. METHODS This was a single-center-matched case-control study in infants ≤30 weeks' gestation receiving ≤30% FiO2 weaned off CPAP during the first postnatal week. Cases were infants placed back on CPAP within 7 days of being taken off CPAP, whereas control infants remained off CPAP for 7 consecutive days following CPAP discontinuation. Infants were matched on gestational age at birth (±10 days). Prospectively collected histograms detailing the distribution of oxygen saturations prior to CPAP discontinuation were compared between cases and controls. RESULTS Over a 12-month monitoring period, 36 infants met inclusion criteria. Baseline characteristics, morbidities, and clinical variables did not differ between cases and controls. Controls achieved oxygen saturations of 95-97 and 97-100% for longer duration compared to cases (p < 0.05). CONCLUSIONS In preterm infants with RDS receiving CPAP and ≤30% FiO2, infants with higher oxygen saturations had greater success in transitioning off CPAP.

Abstract
Heated, humidified, nasal high-flow (HF) therapy is a promising treatment for preterm infants, and almost certainly has a place in the clinical care of this population. It is only in the last few years that data have become available from randomized trials comparing HF with other noninvasive respiratory support modes, particularly nasal continuous positive airway pressure. This article discusses the evidence for HF use from randomized clinical trials in preterm infants and proposes recommendations for evidence-based practice.

Abstract
Continuous positive airway pressure (CPAP) has been used for respiratory support in premature infants for more than 40 years and is now a cornerstone of modern neonatal care. Clinical research on CPAP has primarily focused on understanding which devices and pressure sources best implement this therapy. In contrast, less research has examined the optimal duration over which CPAP is administered. We review this aspect of CPAP therapy.

Abstract
The use of high-flow nasal cannula (HF) therapy as respiratory support for preterm infants is rapidly increasing, due to its perceived ease of use and other potential benefits over the standard 'non-invasive' respiratory support, continuous positive airway pressure (CPAP). The evidence from randomized trials suggests that HF is an alternative to CPAP for post-extubation support of preterm infants. Limited data are available from randomized trials comparing HF with CPAP as primary support, and few trials have included extremely preterm infants. This review discusses the proposed mechanisms of action of HF, the evidence from clinical trials of HF use in preterm infants, and proposes recommendations for evidence-based practice.

Abstract
BACKGROUND High flow nasal cannulae (HFNC) are small, thin, tapered binasal tubes that deliver oxygen or blended oxygen/air at gas flows of more than 1 L/min. HFNC are increasingly being used as a form of non-invasive respiratory support for preterm infants. OBJECTIVES To compare the safety and efficacy of HFNC with other forms of non-invasive respiratory support in preterm infants. SEARCH METHODS We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 1), MEDLINE via PubMed (1966 to 1 January 2016), EMBASE (1980 to 1 January 2016), and CINAHL (1982 to 1 January 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA Randomised or quasi-randomised trials comparing HFNC with other non-invasive forms of respiratory support in preterm infants immediately after birth or following extubation. DATA COLLECTION AND ANALYSIS The authors extracted and analysed data, and calculated risk ratio, risk difference and number needed to treat for an additional beneficial outcome. MAIN RESULTS We identified 15 studies for inclusion in the review. The studies differed in the interventions compared (nasal continuous positive airway pressure (CPAP), nasal intermittent positive pressure ventilation (NIPPV), non-humidified HFNC, models for delivering HFNC), the gas flows used and the indications for respiratory support (primary support from soon after birth, post-extubation support, weaning from CPAP support). When used as primary respiratory support after birth compared to CPAP (4 studies, 439 infants), there were no differences in the primary outcomes of death (typical risk ratio (RR) 0.36, 95% CI 0.01 to 8.73; 4 studies, 439 infants) or chronic lung disease (CLD) (typical RR 2.07, 95% CI 0.64 to 6.64; 4 studies, 439 infants). HFNC use resulted in longer duration of respiratory support, but there were no differences in other secondary outcomes. One study (75 infants) showed no differences between HFNC and NIPPV as primary support. Following extubation (total 6 studies, 934 infants), there were no differences between HFNC and CPAP in the primary outcomes of death (typical RR 0.77, 95% CI 0.43 to 1.36; 5 studies, 896 infants) or CLD (typical RR 0.96, 95% CI 0.78 to 1.18; 5 studies, 893 infants). There was no difference in the rate of treatment failure (typical RR 1.21, 95% CI 0.95 to 1.55; 5 studies, 786 infants) or reintubation (typical RR 0.91, 95% CI 0.68 to 1.20; 6 studies, 934 infants). Infants randomised to HFNC had reduced nasal trauma (typical RR 0.64, 95% CI 0.51 to 0.79; typical risk difference (RD) -0.14, 95% CI -0.20 to -0.08; 4 studies, 645 infants). There was a small reduction in the rate of pneumothorax (typical RR 0.35, 95% CI 0.11 to 1.06; typical RD -0.02, 95% CI -0.03 to -0.00; 5 studies 896 infants) in infants treated with HFNC. Subgroup analysis found no difference in the rate of the primary outcomes between HFNC and CPAP in preterm infants in different gestational age subgroups, though there were only small numbers of extremely preterm and late preterm infants. One trial (28 infants) found similar rates of reintubation for humidified and non-humidified HFNC, and two other trials (100 infants) found no difference between different models of equipment used to deliver humidified HFNC. For infants weaning from non-invasive respiratory support (CPAP), two studies (149 infants) found that preterm infants randomised to HFNC had a reduced duration of hospitalisation compared with infants who remained on CPAP. AUTHORS' CONCLUSIONS HFNC has similar rates of efficacy to other forms of non-invasive respiratory support in preterm infants for preventing treatment failure, death and CLD. Most evidence is available for the use of HFNC as post-extubation support. Following extubation, HFNC is associated with less nasal trauma, and may be associated with reduced pneumothorax compared with nasal CPAP. Further adequately powered randomised controlled trials should be undertaken in preterm infants comparing HFNC with other forms of primary non-invasive support after birth and for weaning from non-invasive support. Further evidence is also required for evaluating the safety and efficacy of HFNC in extremely preterm and mildly preterm subgroups, and for comparing different HFNC devices.

Abstract
Non-invasive techniques, include nasal continuous positive airways pressure (nCPAP), nasal intermittent positive pressure ventilation (NIPPV) and heated, humidified, high flow cannula (HHFNC). Randomised controlled trials (RCTs) of nCPAP versus ventilation have given mixed results, but one demonstrated fewer respiratory problems during infancy. Meta-analysis demonstrated NIPPV rather than nCPAP provided better support post extubation. After extubation or initial support HHFNC has similar efficacy to CPAP. Invasive techniques include those that synchronise inflations with the patient's respiratory efforts. Assist control/ synchronised intermittent mandatory ventilation compared to non triggered modes only reduce the duration of ventilation. Further data are required to determine the efficacy of proportional assist ventilation and neurally adjusted ventilatory assist. Other techniques aim to minimise volutrauma. RCTs of volume targeted ventilation demonstrated reductions in BPD and respiratory medication usage at follow-up. Prophylactic high frequency oscillatory ventilation does not reduce BPD, but is associated with superior lung function at school age.

Abstract
BACKGROUND Nasal continuous positive airway pressure (NCPAP) is frequently used in preterm infants. However, there is no consensus on when and how to wean them from NCPAP. DATA SOURCES Based on recent publications, we have reviewed the criteria of readiness-to-wean and factors affecting weaning success. A special focus is placed on the methods of weaning from NCPAP in preterm infants. RESULTS Practical points of when and how to wean from NCPAP in preterm infants are explained. Preterm infants are ready to be weaned from NCPAP when they are stable on a low NCPAP pressure with no (or minimal) oxygen requirement. Methods used to wean from NCPAP include: sudden weaning of NCPAP, gradual decrease of NCPAP pressure, graded-timeoff NCPAP (cycling), weaning to high or low flow nasal cannula, and a combination of these methods. The best strategy for weaning is yet to be determined. Cyclingoff NCPAP increases the duration of NCPAP and length of hospital stay without beneficial effect on success of weaning. Gradual decrease of NCPAP pressure is more physiological and better tolerated than cycling-off NCPAP. CONCLUSION Further studies are needed to reach a consensus regarding the optimal timing and the best method for weaning from NCPAP in preterm infants.

Abstract
PURPOSE OF THE REVIEW Noninvasive respiratory support for neonates is growing in popularity as clinicians increasingly recognize the dangers of prolonged invasive ventilation. The purpose of this review is to critically evaluate the existing evidence for safety and efficacy of these modes of respiratory support in neonates. RECENT FINDINGS In recent years, multiple randomized controlled trials (RCTs) have evaluated several modes of noninvasive support, most importantly nasal intermittent positive pressure ventilation and high flow nasal cannulae, in comparison to the standard therapy of continuous positive airway pressure (CPAP). The three largest RCTs were recently published in 2013. One demonstrated no difference in death or survival with bronchopulmonary dysplasia between nasal intermittent positive pressure ventilation and CPAP, both when used as primary support and as postextubation support. Two others demonstrated that high flow nasal cannulae are noninferior to or no better than CPAP when used to support preterm infants after extubation. These trials showed no serious safety concerns with current modalities. SUMMARY The optimal forms of noninvasive respiratory support for neonates remain to be determined. Continued evaluation of these technologies with large, well-designed RCTs is warranted.
