RESUMO

BACKGROUND: Cyclooxygenase inhibitors are commonly used in infants with patent ductus arteriosus (PDA), but the benefit of these drugs is uncertain. METHODS: In this multicenter, noninferiority trial, we randomly assigned infants with echocardiographically confirmed PDA (diameter, >1.5 mm, with left-to-right shunting) who were extremely preterm (<28 weeks' gestational age) to receive either expectant management or early ibuprofen treatment. The composite primary outcome included necrotizing enterocolitis (Bell's stage IIa or higher), moderate to severe bronchopulmonary dysplasia, or death at 36 weeks' postmenstrual age. The noninferiority of expectant management as compared with early ibuprofen treatment was defined as an absolute risk difference with an upper boundary of the one-sided 95% confidence interval of less than 10 percentage points. RESULTS: A total of 273 infants underwent randomization. The median gestational age was 26 weeks, and the median birth weight was 845 g. A primary-outcome event occurred in 63 of 136 infants (46.3%) in the expectant-management group and in 87 of 137 (63.5%) in the early-ibuprofen group (absolute risk difference, -17.2 percentage points; upper boundary of the one-sided 95% confidence interval [CI], -7.4; P<0.001 for noninferiority). Necrotizing enterocolitis occurred in 24 of 136 infants (17.6%) in the expectant-management group and in 21 of 137 (15.3%) in the early-ibuprofen group (absolute risk difference, 2.3 percentage points; two-sided 95% CI, -6.5 to 11.1); bronchopulmonary dysplasia occurred in 39 of 117 infants (33.3%) and in 57 of 112 (50.9%), respectively (absolute risk difference, -17.6 percentage points; two-sided 95% CI, -30.2 to -5.0). Death occurred in 19 of 136 infants (14.0%) and in 25 of 137 (18.2%), respectively (absolute risk difference, -4.3 percentage points; two-sided 95% CI, -13.0 to 4.4). Rates of other adverse outcomes were similar in the two groups. CONCLUSIONS: Expectant management for PDA in extremely premature infants was noninferior to early ibuprofen treatment with respect to necrotizing enterocolitis, bronchopulmonary dysplasia, or death at 36 weeks' postmenstrual age.

RESUMO

To compare the effects of neurally adjusted ventilatory assist (NAVA) with other forms of synchronized artificial ventilation in preterm infants. A systematic review of randomized and quasi-randomized controlled trials with individual group allocation, both parallel-group trials as well as crossover trials, that included preterm infants born at less than 37 weeks gestational age and compared NAVA with any other form of synchronized mechanical ventilation with or without volume guarantee. Primary outcomes were death or bronchopulmonary dysplasia (BPD) at 36 weeks, total duration of respiratory support and neurodevelopmental outcome at 2 years. Secondary outcomes consisted of important procedural and clinical outcomes. Seven studies with a total of 191 infants were included, five randomized crossover trials and two parallel group randomized trials. No significant difference in the primary outcome of death or BPD (RR: 1.08, 95% CI: 0.33-3.55) was found. Peak inspiratory pressures were significantly lower with NAVA than with other forms of ventilation (MD -1.83 cmH2O [95% CI: -2.95 to -0.71]). No difference in any other clinical or ventilatory outcome was detected. Although associated with lower peak inspiratory pressures, the use of NAVA does not result in a reduced risk of death or BPD as compared to other forms of synchronized ventilation in preterm infants. However, the certainty of evidence is low due to imprecision of the effect estimate. Larger studies are needed to detect possible short- and long-term differences between ventilation modes.

RESUMO

The INtubation-SURfactant-Extubation (INSURE) procedure is a widely-used surfactant administration method to treat preterm infants with respiratory distress syndrome (RDS) but is not always successful. We conducted a systematic review to identify early predictive factors for failure of this procedure. A systematic literature search was performed until July 2018 in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Original studies comparing INSURE success with INSURE failure in preterm infants with RDS were included. A predefined data extraction form was used to retrieve data from articles, and methodological quality was assessed using the SIGN checklists. Fifteen studies out of 690 identified records met inclusion criteria. Methodological quality varied, only 8 studies performed multivariate analysis. We identified 20 different risk factors in total. Evidence for birth weight (BW) as a predictor for INSURE failure was inconsistent, but there was a significant association between decreasing gestational age (GA) and failure risk. RDS severity was assessed in multiple ways, using arterial blood gas values, imaging, and scoring systems. In conclusion, extremely low BW, low GA, and severe RDS appear to be risk factors for INSURE failure. However, evidence is inconsistent due to important methodological heterogeneity. Therefore, clinical applicability of these results is limited and implies the need for future large cohort studies on this subject.

RESUMO

Diaphragmatic paralysis is a rare cause of respiratory distress in the newborn. In this paper, a patient with unilateral phrenic nerve injury after traumatic delivery is presented. The child inadequately responded to standard respiratory supportive measures. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA®), providing an optimally synchronized respiratory support proportional to the effort of the patient, resulted in prompt clinical and biological improvement of the patient's respiratory condition. NAVA is a relatively new mode of ventilation in neonatal care. In this case of unilateral diaphragmatic paralysis, it provided an alternative strategy of non-invasive respiratory support avoiding prolonged mechanical ventilation.
