The Subdiaphragmatic Angle Of The Gastric Tube In Neonates - A Potential Predictor For Perforations?

BACKGROUND: Traumatic subdiaphramatic perforation of esophagus or stomach in neonates represents a rare clinical complication following the insertion of a gastric tube and is associated with high morbidity and mortality. The aim of the present study was to evaluate whether the angle of the gastric tube depicted on a plain radiograph may serve as a diagnostic tool to predict subdiaphragmatic traumatic (or iatrogenic) perforation. PATIENTS AND METHODS: Thoraco-abdominal radiographs of 128 preterm and term neonates without perforation and 15 neonates with perforation of the esophagogastric junction or the stomach were retrospectively analysed. RESULTS: The angle of the gastric tube increases with postnatal age (p=0.0380). In the control group, the angle of the gastric tube varied between 13° and 48° (median: 31°), whereas the values ranged from -31° to 42° (median: 11°) in neonates with subdiaphragmatic perforation. Perforation should thus be suspected in cases with an angle of<20° (sensitivity: 93.3%; specificity: 91.4%). Moreover, an unusual localization of the tip beyond the gastric bubble is highly indicative of perforation. DISCUSSION: The present study emphasizes the importance of verifying the correct course of an inserted gastric tube. CONCLUSIONS: In daily clinical practice, an angle of<20° should be followed by thorough physical examination, abdominal ultrasound and if applicable contrast medium examinations to exclude perforation.

Short-term neonatal outcomes in vaginal breech delivery: Results of a retrospective single-centre study.

BACKGROUND: Vaginal breech delivery (VBD) has been widely discouraged over the last two decades due to associated neonatal risks. However, many gynaecologists are still challenging this approach, at least in selected settings. OBJECTIVE: To study short-term neonatal outcomes in singleton pregnancies undergoing VBD. MATERIALS AND METHODS: Retrospective cohort study conducted on singleton pregnancies who delivered in breech presentation between 2012 and 2019. Neonatal complications in terms of mortality, umbilical artery (UA) pH, 5-min Apgar score, and postnatal admission to neonatal intensive care unit (NICU) were evaluated. RESULTS: Overall, 804 breech deliveries were considered. Of these, 53.86 % had VBD, 26.62 % had emergency caesarean sections (CS) and 19.53 % had elective CS. No perinatal deaths were reported. After multivariate adjustment, VBD was associated with higher incidence of UA pH < 7.10 compared with both elective and emergency CS. No significant associations were found between VBD and UA pH < 7.00 or 5-min Apgar score < 3 or < 7. No significant differences in NICU hospitalization were observed for different modes of delivery. Gestational age was inversely correlated with UA pH < 7.00, 5-min Apgar score < 3 and < 7, and NICU hospitalization. CONCLUSIONS: VBD in an experienced setting does not increase the risk of negative short-term perinatal outcomes significantly. Gestational age was the most important risk factor for low UA pH or 5-min Apgar score and NICU hospitalization, independent of mode of delivery.

Active perinatal care of preterm infants in the German Neonatal Network.

OBJECTIVE: To determine if survival rates of preterm infants receiving active perinatal care improve over time. DESIGN: The German Neonatal Network is a cohort study of preterm infants with birth weight <1500 g. All eligible infants receiving active perinatal care are registered. We analysed data of patients discharged between 2011 and 2016. SETTING: 43 German level III neonatal intensive care units (NICUs). PATIENTS: 8222 preterm infants with a gestational age between 22/0 and 28/6 weeks who received active perinatal care. INTERVENTIONS: Participating NICUs were grouped according to their specific survival rate from 2011 to 2013 to high (percentile >P75), intermediate (P25-P75) and low (

FUT 2 polymorphism and outcome in very-low-birth-weight infants.

BACKGROUND: To determine whether the secretor gene fucosyltransferase (FUT)2 polymorphism G428A is predictive for adverse outcomes in a large cohort of very-low-birth weight (VLBW) infants. METHODS: We prospectively enrolled 2,406 VLBW infants from the population-based multicenter cohort of the German Neonatal network cohort (2009-2011). The secretor genotype (rs601338) was assessed from DNA samples extracted from buccal swabs. Primary study outcomes were clinical sepsis, blood-culture confirmed sepsis, intracerebral hemorrhage (ICH), necrotizing enterocolitis (NEC) or focal intestinal perforation requiring surgery, and death. RESULTS: Based on the assumption of a recessive genetic model, AA individuals had a higher incidence of ICH (AA: 19.0% vs. GG/AG: 14.9%, P = 0.04) which was not significant in the additive genetic model (multivariable logistic regression analysis; allele carriers: 365 cases, 1,685 controls; OR: 1.2; 95% CI: 0.99-1.4; P = 0.06). Other outcomes were not influenced by FUT2 genotype in either genetic model. CONCLUSION: This large-scale multicenter study did not confirm previously reported associations between FUT2 genotype and adverse outcomes in preterm infants.
