ABSTRACT

OBJECTIVE: To determine the prevalence of pulmonary hypertension (PAH) in left-sided congenital diaphragmatic hernia (CDH); how we could predict it; and how PAH contributed to the model for mortality prediction. STUDY DESIGN: Retrospective analysis in three European centers. The primary outcome was the presence of PAH on postnatal day (d) 1, 7, and at discharge. Studied predictors of PAH were: observed/expected-lung/head-ratio (o/e LHR), liver-herniation, fetoscopic endoluminal tracheal occlusion (FETO), and gestational age (GA) at delivery. The combined effect of pre- and postnatal variables on mortality was modeled by Cox regression. RESULTS: Of the 197 neonates, 56 (28.4%) died. At d1, 67.5% (133/197) had PAH and 61.9% (101/163) by d7. Overall, 6.4% (9/141) had PAH at discharge. At d1, o/e LHR (odds ratio (OR) 0.96) and FETO (OR 2.99) independently correlated to PAH (areas under the curve [AUC]: 0.74). At d7, PAH significantly correlated only with the use of FETO (OR 3.9; AUC: 0.65). None were significant for PAH at discharge. Combining the occurrence of PAH with antenatal biomarkers improved mortality prediction (p = 0.02), in a model including o/e LHR (HR: 0.94), FETO (HR: 0.35), liver herniation (HR: 16.78), and PAH (HR: 15.95). CONCLUSIONS: Antenatal prediction of PAH was only moderate. The postnatal occurrence of PAH further increases the risk of death. Whereas this may be used to counsel parents in the postnatal period, our study demonstrates there is a need to find more accurate antenatal predictors for PAH.

ABSTRACT

The precise moment for weaning a patient off extracorporeal membrane oxygenation (ECMO) is not always easy to establish. Also, mechanical causes may obligate to disconnect the patient from the circuit before the optimal weaning off. In these selected cases, the patient can be disconnected from the circuit and the cannula can be left in place (stand-by cannula) until the patient's stability without ECMO is assured. The aim was to describe our experience with the stand-by cannula. Single-institution, long-term retrospective study in a pediatric tertiary care hospital. Neonatal and pediatric patients who were under ECMO and needed stand-by cannula before definitive de-cannulation were included. During 18 years, 166 children required ECMO. In 31 patients (18.7%), stand-by cannula was performed before the weaning off. Twenty patients (64.5%) were newborn. The main reason for requiring ECMO in these newborn was persistent pulmonary hypertension. Eleven patients were pediatric and their main cause for requiring ECMO was cardiogenic shock (six patients, 54.4%). The reasons for requiring stand-by cannula were the uncertainty of a successful weaning off in 17 patients (54.8%), to undergo surgery in 10 patients (32.3%) and to replace the circuit in four cases (12.9%). The median duration of stand-by cannula was 12 h (IQR 6-24). Heparinized saline serum was the main maintenance perfusion (28 patients, 90.3%). Three patients needed to restart support with ECMO. Only one mechanical complication was detected. Stand-by cannula is a safe technique, which allows performing a quick re-entrance on ECMO if the weaning off fails.

ABSTRACT

PURPOSE: Recurrence of congenital diaphragmatic hernia (CDH) is a treatment-related morbidity which can be preventable. There is no consensus about the ideal material for diaphragmatic substitution. The aim of our study is to identify if the use of porcine dermis patches increases the risk of CDH recurrence. METHODS: Retrospective review of medical records of CDH patients treated between 2013 and 2017 in our center was carried out. Demographic, clinical and surgical variables were collected. Regression analysis was performed to identify which factors increase the risk of recurrence. RESULTS: 50 patients entered the study. 94% of the patients had a left CDH, mean observed/expected lung-to-head ratio was 46%. 17 patients underwent a primary closure, the rest a patch closure: 25 Gore-Tex® and 8 porcine dermis patches were used. Seven patients presented recurrence (14%). Median follow-up time was 3.5 years (1.2-6.2). Univariate analysis revealed that the use of a porcine dermis patch (75%) increased the risk of recurrence compared with Gore-Tex® patch (4%) and primary closure (0%) p < 0.001 (HR 58.7; IC 95%: 6.9-501.2; p < 0.001). CONCLUSION: The main risk factor for CDH recurrence is the use of a porcine dermis patch. We do not recommend the use of these patches for CDH repair.

ABSTRACT

BACKGROUND: The role of chorioamnionitis in neurodevelopment of preterm infants is not fully understood. AIM: To examine the association between different indicators of intrauterine inflammation (clinical chorioamnionitis, histological chorioamnionitis and funisitis) and neurodevelopmental impairment in very preterm infants. METHODS: Preterm infants with a birth weight of <1500 g or a gestational age of <32 weeks were included. Follow-up evaluation up to 2 years of age consisted of neurological examination, neurodevelopmental assessment and visual and audiologic tests. Outcome data were compared between the chorioamnionitis and the control groups, controlling for gestational age, birth weight and Apgar score at 5 min. RESULTS: One hundred seventy-seven patients comprised the study population (mean gestational age 29±2 weeks, mean birth weight 1167±344 g). Histological chorioamnionitis was present in 49% of placentas, whereas funisitis was observed in 25%. In 57% cases clinical maternal chorioamnionitis was suspected. Follow-up was available for 130 (82%) patients. Infants with funisitis, compared with controls, had a significantly higher incidence of moderate to severe disability (18% vs 5%, OR 4.07; 95% CI 1.10-15.09). CONCLUSION: The results of this study suggest that, unlike a broad definition of histological chorioamnionitis including inflammation of maternal or fetal placental tissues, funisitis may entail a higher risk of moderate to severe disability at 2 years of age in preterm infants.
