Nabelvenenkatheter- und periphere zentrale katheterassoziierte Komplikationen bei Frühgeborenen mit einem Geburtsgewicht < 1250 g : Ergebnisse einer Umfrage in Österreich und Deutschland

Background and objective Umbilical venous catheters (UVC) and peripherally inserted central catheters (PICC) are commonly used in preterm infants but have been associated with a number of serious complications. We performed a survey in Austria and Germany to assess the use of UVCs and PICCs in preterm infants with a birth weight < 1250 g and associated rates of catheter-related adverse events. Methods Electronic survey of participating centers of the NeoVitaA trial. Main outcome parameter was the reported rates of UVC- and PICC-associated complications (infection, thrombosis, emboli, organ injury, arrhythmia, dislocation, miscellaneous). Results In total, 20 neonatal intensive care units (NICU) providing maximal intensive care in Austria and Germany (level I) were contacted, with a senior neonatologist response rate of 12/20 (60%). The reported rates for UVC with a dwell time of 1–10 days were bacterial infection: 4.2 ± 3.4% (range 0–10%); thrombosis: 7.3 ± 7.1% (0–20%); emboli: 0.9 ± 2.0% (0–5%); organ injury: 1.1 ± 1.9% (0–5%); cardiac arrhythmia: 2.2 ± 2.5% (0–5%); and dislocation: 5.4 ± 8.7% (0–30%); and for PICCs with a dwell time of 1–14 days bacterial infection: 15.0 ± 3.4% (range 2.5–30%); thrombosis; 4.3 ± 3.5% (0–10%); emboli: 0.8 ± 1.6% (0–5%); organ injury: 1.5 ± 2.3% (0–5%); cardiac arrhythmia: 1.5 ± 2.3% (0–5%), and dislocation: 8.5 ± 4.6% (0–30%). Conclusion The catheter-related complication rates reported in this survey differed between UVCs and PICCs and were higher than those reported in the literature. To generate more reliable data on this clinically important issue, we plan to perform a large prospective multicenter randomized controlled trial investigating the non-inferiority of a prolonged UVC dwell time (up to 10 days) against the early change (up to 5 days) to a PICC.Hintergrund und Ziel Nabelvenenkatheter („umbilical venous catheters“ [UVC]) und periphere zentrale Venenkatheter (PICC) werden häufig bei Frühgeborenen eingesetzt, sind jedoch mit einer Reihe von schwerwiegenden Komplikationen verbunden. In Österreich und Deutschland wurde eine Umfrage durchgeführt, um die Verwendung von UVC und PICC bei Frühgeborenen mit einem Geburtsgewicht < 1250 g und die damit verbundenen Raten von katheterbedingten unerwünschten Ereignissen zu bewerten. Methoden Elektronische Befragung der teilnehmenden Zentren der NeoVitaA-Studie. Hauptergebnisparameter waren die gemeldeten Raten von UVC- und PICC-assoziierten Komplikationen (Infektion, Thrombose, Embolie, Organverletzung, Arrhythmie, Dislokation, Sonstiges). Ergebnisse Insgesamt wurden 20 neonatale Intensivstationen (NICU) mit maximaler Intensivpflege in Österreich und Deutschland (Level I) kontaktiert, wobei 12/20 (60 %) von leitenden Neonatologen beantwortet wurden. Die gemeldeten Raten für UVC mit einer Verweildauer von 1 bis 10 Tagen waren bakterielle Infektionen: 4,2 ± 3,4 % (Bereich: 0–10 %); Thrombose: 7,3 ± 7,1 % (0–20 %); Embolie: 0,9 ± 2,0 % (0–5 %); Organverletzung: 1,1 ± 1,9 % (0–5 %); Herzrhythmusstörungen: 2,2 ± 2,5 % (0–5 %); und Dislokation: 5,4 ± 8,7% (0–30 %); und bei PICC mit einer Verweildauer von 1 bis 14 Tagen bakterielle Infektionen: 15,0 ± 3,4 % (Bereich: 2,5–30 %); Thrombose: 4,3 ± 3,5 % (0–10 %); Embolie: 0,8 ± 1,6 % (0–5 %); Organverletzung: 1,5 ± 2,3 % (0–5 %); Herzrhythmusstörungen: 1,5 ± 2,3 % (0–5 %) und Verrenkungen: 8,5 ± 4,6 % (0–30 %). Schlussfolgerung Die in dieser Umfrage berichteten katheterbedingten Komplikationsraten unterschieden sich zwischen UVC und PICC und waren höher als die in der Literatur berichteten. Um zuverlässigere Daten zu diesem klinisch wichtigen Thema zu erhalten, ist eine große prospektive, multizentrische, randomisierte, kontrollierte Studie geplant, in der die Nichtunterlegenheit einer verlängerten UVC-Verweildauer (bis zu 10 Tage) gegenüber dem frühen Wechsel (bis zu 5 Tage) zu einem PICC untersucht werden soll

Lactobacillus Acidophilus/Bifidobacterium Infantis Probiotics Are Beneficial to Extremely Low Gestational Age Infants Fed Human Milk

To evaluate the nutrition-related effects of prophylactic Lactobacillus acidophilus/ Bifidobacterium infantis probiotics on the outcomes of preterm infants <29 weeks of gestation that receive human milk and/or formula nutrition. We hypothesize that human-milk-fed infants benefit from probiotics in terms of sepsis prevention and growth. Methods: We performed an observational study of the German Neonatal Network (GNN) over a period of six years, between 1 January, 2013 and 31 December, 2018. Prophylactic probiotic use of L. acidophilus/B. infantis was evaluated in preterm infants <29 weeks of gestation (n = 7516) in subgroups stratified to feeding type: (I) Exclusively human milk (HM) of own mother and/or donors (HM group, n = 1568), (II) HM of own mother and/or donor and formula (Mix group, n = 5221), and (III) exclusive exposure to formula (F group, n = 727). The effect of probiotics on general outcomes and growth was tested in univariate models and adjusted in linear/logistic regression models. Results: 5954 (76.5%) infants received L. acidophilus/B. infantisprophylactically for the prevention of necrotizing enterocolitis (NEC). Probiotic use was associated with improved growth measures in the HM group (e.g., weight gain velocity in g/day: effect size B = 0.224; 95% CI: 2.82–4.35; p < 0.001) but not in the F group (effect size B = −0.06; 95% CI: −3.05–0.28; p = 0.103). The HM group had the lowest incidence of clinical sepsis (34.0%) as compared to the Mix group (35.5%) and the F group (40.0%). Only in the Mix group, probiotic supplementation proved to be protective against clinical sepsis (OR 0.69; 95% CI: 0.59–0.79; p < 0.001). Conclusion: Our observational data indicate that the exposure to L. acidophilus/B. infantis probiotics may promote growth in exclusively HM-fed infants as compared to formula-fed infants. To exert a sepsis-preventive effect, probiotics seem to require human milk

Epidemic Microclusters of Blood-Culture Proven Sepsis in Very-Low-Birth Weight Infants: Experience of the German Neonatal Network

INTRODUCTION: We evaluated blood culture-proven sepsis episodes occurring in microclusters in very-low-birth-weight infants born in the German Neonatal Network (GNN) during 2009-2010. METHODS: Thirty-seven centers participated in GNN; 23 centers enrolled ≥50 VLBW infants in the study period. Data quality was approved by on-site monitoring. Microclusters of sepsis were defined as occurrence of at least two blood-culture proven sepsis events in different patients of one center within 3 months with the same bacterial species. For microcluster analysis, we selected sepsis episodes with typically cross-transmitted bacteria of high clinical significance including gram-negative rods and Enterococcus spp. RESULTS: In our cohort, 12/2110 (0.6%) infants were documented with an early-onset sepsis and 235 late-onset sepsis episodes (≥72 h of age) occurred in 203/2110 (9.6%) VLBW infants. In 182/235 (77.4%) late-onset sepsis episodes gram-positive bacteria were documented, while coagulase negative staphylococci were found to be the most predominant pathogens (48.5%, 95%CI: 42.01-55.01). Candida spp. and gram-negative bacilli caused 10/235 (4.3%, 95%CI: 1.68% -6.83%) and 43/235 (18.5%) late-onset sepsis episodes, respectively. Eleven microclusters of blood-culture proven sepsis were detected in 7 hospitals involving a total 26 infants. 16/26 cluster patients suffered from Klebsiella spp. sepsis. The median time interval between the first patient's Klebsiella spp. sepsis and cluster cases was 14.1 days (interquartile range: 1-27 days). First patients in the cluster, their linked cases and sporadic sepsis events did not show significant differences in short term outcome parameters. DISCUSSION: Microclusters of infection are an important phenomenon for late-onset sepsis. Most gram-negative cluster infections occur within 30 days after the first patient was diagnosed and Klebsiella spp. play a major role. It is essential to monitor epidemic microclusters of sepsis in surveillance networks to adapt clinical practice, inform policy and further improve quality of care

Rheological parameters in the umbilical cord blood in moderate and severe forms of preeclampsia

Rheological blood parameters of neonates are different form those of adults. Many authors have studied changes in blood rheology in neonates in different clinical disorders. To-date, no one set the normal values for blood rheological parameters in healthy neonates. The aim of this study is to set the norm for rheological blood parameters in healthy newborns and to describe the changes in those parameters in common clinical disorders that affect the newborns. We recruited all the neonates born to mothers experiencing un eventful pregnancies, blood was taken from the umbilical cord right after the delivery. In this time period we recruited 4985 neonate. From this huge database we were able to set the standards for blood rheology in neonates, namely plasma viscosity of 1.06 ? 0.072 mPa, erythrocyte aggregation at stasis of 2.41 ? 2.74 s-1 and erythrocyte aggregation under low shear forces of 8.51 ? 6.38 s-1. These values changed significantly in some diseased neonates. This is the largest study investigating normal rheological parameters and deviations from the norm in common clinical disorders occurring in this early stage of lif

Iatrogenic severe hyperglycemia due to parenteral administration of glucose in children – a case series

Background!#!Iatrogenic severe hyperglycemia (ISH) caused by glucose-containing i.v. solution is a potentially fatal treatment error. The objective of this study was to investigate the causes, circumstances, course of disease, and complications of ISH &amp;gt; 300 mg/dl (16.7 mmol/l) in neonates and children.!##!Methods!#!We emailed a survey to 105 neonatal and pediatric intensive care units in Germany, Austria, and Switzerland, asking to retrospectively report cases of ISH.!##!Results!#!We received 11 reports about premature infants to children. Four patients (36%) had poor outcome: 2 died and 2 suffered persistent sequelae. The highest observed blood glucose was at median 983 mg/dl (54.6 mmol/l) (range 594-2240 mg/dl; 33.0-124.3 mmol/l) and median time to normoglycemia was 7 h (range 2-23). Blood glucose was higher and time to normoglycemia longer in patients with poor outcome. Invasive therapy was required in 73% (mechanical ventilation) and 50% (vasopressor therapy) of patients, respectively. Administration of insulin did not differ between outcome groups. Patients with poor outcome showed coma (100% vs. 40%) and seizures (75% vs. 29%) more frequently than those with good outcome.!##!Conclusions!#!ISH is a severe condition with high morbidity and mortality. Further research to amplify the understanding of this condition is needed, but focus should largely be held on its prevention
