243898.pdf (Publisher’s version ) (Open Access)OBJECTIVE: There is generally limited but conflicting literature on the incidence, causes, and outcomes of pediatric out-of-hospital cardiac arrest. This study was performed to determine the incidence and outcome of pediatric out-of-hospital cardiac arrest reported by all helicopter emergency medical services in the Netherlands and to provide a description of causes and treatments and, in particular, a description of the specific interventions that can be performed by a physician-staffed helicopter emergency medical service. METHODS: A retrospective analysis was performed of all documented pediatric (0 < 18 years of age) out-of-hospital cardiac arrests from July 2015 to July 2017, attended by all 4 Dutch helicopter emergency medical service teams. RESULTS: Two hundred two out-of-hospital cardiac arrests were identified. The overall incidence in the Netherlands is 3.5 out-of-hospital cardiac arrests in children per 100,000 pediatric inhabitants. The overall survival rate for out-of-hospital cardiac arrest was 11.4%. Eleven (52%) of the survivors were in the drowning group and between 12 and 96 months of age. CONCLUSION: Helicopter emergency medical services are frequently called to pediatric out-of-hospital cardiac arrests in the Netherlands. The survival rate is normal to high compared with other countries. The 12- to 96-month age group and drowning seem to have a relatively favorable outcome
Characteristics, management and outcome of prehospital pediatric emergencies by a Dutch HEMS
Background: In prehospital care, the Helicopter Emergency Medical Service (HEMS) can be dispatched for critically injured or ill children. However, little detail is known about dispatches for children, in terms of the incidence of prehospital interventions and overall mortality. The primary objective of this study is to provide an overview of pediatric patient characteristics and incidence of interventions. Methods: A retrospective chart review of all patients ≤ 17 years who received medical care by Rotterdam HEMS from 2012 until 2017 was carried out. Results: During the study period, 1905 pediatric patients were included. 59.1% of patients were male and mean age was 6.1 years with 53.2% of patients aged ≤ 3 years. 53.6% were traumatic patients and 49.7% were non-traumatic patients. 18.8% of patients were intubated. Surgical procedures were performed in 0.9%. Medication was administered in 58.1% of patients. Cardiopulmonary resuscitation (CPR) was necessary in 12.9% of patients, 19.9% were admitted to the intensive care unit and 14.0% needed mechanical ventilation. Overall mortality was 9.5%. Mortality in trauma patients was 5.5% and in non-trauma group 15.3%. 3.9% of patients died at the scene. Conclusions: Patients attended by HEMS are at high risk of prehospital interventions like CPR or intubation. EMS has little exposure to critically ill or injured children. Hence, HEMS expertise is required to perform critical procedures. Trauma patients had higher survival rates than non-traumatic patients. This may be explained by underlying illnesses in non-traumatic patients and CPR as reason for dispatch. Further research is needed to identify options for improving prehospital care in the non trauma pediatric patients
The sublingual microcirculation throughout neonatal and pediatric extracorporeal membrane oxygenation treatment: Is it altered by systemic extracorporeal support?
Background: Extracorporeal membrane oxygenation (ECMO) treatment alleviates systemic cardiorespiratory failure. However, it is unclear whether ECMO also improves microcirculatory function, as the microcirculation can be disturbed despite normal systemic hemodynamics. We therefore aimed to study the sublingual microcirculation (SMC) throughout neonatal and pediatric ECMO treatment. We hypothesized that the SMC improves after starting ECMO, that the SMC differs between venovenous (VV) and venoarterial (VA) ECMO, and that insufficient recovery of microcirculatory disturbances during ECMO predicts mortality. Methods: This single-center prospective longitudinal observational study included 34 consecutive children (April 2016-September 2018). The SMC was assessed daily with a handheld vital microscope (integrated with incident dark field illumination) before, during, and after ECMO. Validated parameters of vessel density, perfusion, and flow quality were assessed for all vessels (diameter 2.6) increased with higher MAP (OR: 1.050, 95%CI: 1.008-1.094). Microcirculatory parameters did not significantly differ between VV and VA ECMO or between survivors and non-survivors. None of the microcirculatory parameters could predict mortality on ECMO or overall mortality. Conclusion: In this heterogeneous study population, we were not able to demonstrate an effect of ECMO on the sublingual microcirculation. Microcirculatory parameters did not change throughout ECMO treatment and did not differ between VV and VA ECMO or between survivors and non-survivors. Future research should focus on determining which neonatal and pediatric ECMO patients wou
Coagulation complications after conversion from roller to centrifugal pump in neonatal and pediatric extracorporeal membrane oxygenation
Background/purpose: Coagulation complications are frequent, unwanted occurrences in extracorporeal membrane oxygenation (ECMO) treatment, possibly influenced by the pump in the ECMO-circuit. We hypothesized that fewer complications would occur with a smaller, heparin-coated ECMO system with a centrifugal pump (CP) than with one with a roller pump (RP) and that after conversion, complication rates would decrease over time. Methods: This single-center, retrospective chart study included all first neonatal and pediatric ECMO runs between 2009 and 2015. Differences between groups were assessed with Mann–Whitney U tests and Kruskal–Wallis tests. Determinants of complication rates were evaluated through Poisson regression models. The CP group was divided into three consecutive groups to assess whether complication rates decreased over time. Results: The RP group comprised 90 ECMO runs and the CP group 82. Hemorrhagic complication rates were significantly higher with the CP than with the RP, without serious therapeutic consequences, while thrombotic complications rates were unaffected. Intracranial hemorrhage rates and coagulation-related mortality rates were similar. Gained experience with the CP did not improve complication rates or su

Dutch Prospective Observational Study on Prehospital Treatment of Severe Traumatic Brain Injury: The BRAIN-PROTECT Study Protocol
Background: Severe traumatic brain injury (TBI) is associated with a high mortality rate and those that survive
commonly have permanent disability. While there is a
broad consensus that appropriate prehospital treatment is
crucial for a favorable neurological outcome, evidence to
support currently applied treatment strategies is scarce. In
particular, the relationship between prehospital treatments
and patient outcomes is unclear. The BRAIN-PROTECT
study therefore aims to identify prehospital treatment
strategies associated with beneficial or detrimental outcomes. Here, we present the study protocol. Study
Protocol: BRAIN-PROTECT is the acronym for BRAin
INjury: Prehospital Registry of Outcome, Treatments and
Epidemiology of Cerebral Trauma. It is a prospective
observational study on the prehospital treatment of
patients with suspected severe TBI in the Netherlands.
Prehospital epidemiology, interventions, medication strategies, and nonmedical factors that may affect outcome are
studied. Multivariable regression based modeling will be
used to identify confounder-adjusted relationships
between these factors and patient outcomes, including
mortality at 30 days (primary outcome) or mortality and
functional neurological outcome at 1 year (secondary outcomes). Patients in whom severe TBI is suspected during
prehospital treatment (Glasgow Coma Scale score 8 in
combination with a trauma mechanism or clinical findings
suggestive of head injury) are identified by all four helicopter emergency medical services (HEMS) in the
Netherlands. Patients are prospectively followed up in 9
participating trauma centers for up to one year. The
manuscript reports in detail the objectives, setting, study
design, patient inclusion, and data collection process.
Ethical and juridical aspects, statistical considerations, as
well as limitations of the study design are discussed.
Discussion: Current prehospital treatment of patients
with suspected severe TBI is based on marginal evidence,
and optimal treatment is basically unknown. The BRAINPROTECT study provides an opportunity to evaluate and
compare different treatment strategies with respect to
patient outcomes. To our knowledge, this study project is
the first large-scale prospective prehospital registry of
patients with severe TBI that also collects long-term follow-up data and ma
Improving Long-Term Outcomes After Extracorporeal Membrane Oxygenation: From Observational Follow-Up Programs Toward Risk Stratification
Contains fulltext :
196115.pdf (publisher's version ) (Open Access)Since the introduction of extracorporeal membrane oxygenation (ECMO), more neonates and children with cardiorespiratory failure survive. Interest has therefore shifted from reduction of mortality toward evaluation of long-term outcomes and prevention of morbidity. This review addresses the changes in ECMO population and the ECMO-treatment that may affect long-term outcomes, the diagnostic modalities to evaluate neurological morbidities and their contributions to prognostication of long-term outcomes. Most follow-up data have only become available from observational follow-up programs in neonatal ECMO-survivors. The main topics are discussed in this review. Recommendations for long-term follow up depend on the presence of neurological comorbidity, the nature and extent of the underlying disease, and the indication for ECMO. Follow up should preferably be offered as standard of care, and in an interdisciplinary, structured and standardized way. This permits evaluation of outcome data and effect of interventions. We propose a standardized approach and recommend that multiple domains should be evaluated during long-term follow up of neonates and children who needed extracorporeal life support
No association between thickening fraction of the diaphragm and extubation success in ventilated children.
INTRODUCTION: In mechanically ventilated adults, thickening fraction of diaphragm (dTF) measured by ultrasound is used to predict extubation success. Whether dTF can also predict extubation success in children is unclear. AIM: To investigate the association between dTF and extubation success in children. Second, to assess diaphragm thickness during ventilation and the correlation between dTF, diaphragm thickness (Tdi), age and body surface. METHOD: Prospective observational cohort study in children aged 0-18 years old with expected invasive ventilation for >48 h. Ultrasound was performed on day 1 after intubation (baseline), day 4, day 7, day 10, at pre-extubation, and within 24 h after extubation. Primary outcome was the association between dTF pre-extubation and extubation success. Secondary outcome measures were Tdi end-inspiratory and Tdi end-expiratory and atrophy defined as <10% decrease of Tdi end-expiratory versus baseline at pre-extubation. Correlations were calculated with Spearman correlation coefficients. Inter-rater reliability was calculated with intraclass correlation (ICC). RESULTS: Fifty-three patients, with median age 3.0 months (IQR 0.1-66.0) and median duration of invasive ventilation of 114.0 h (IQR 55.5-193.5), were enrolled. Median dTF before extubation with Pressure Support 10 above 5 cmH(2)O was 15.2% (IQR 9.7-19.3). Extubation failure occurred in six children, three of whom were re-intubated and three then received non-invasive ventilation. There was no significant association between dTF and extubation success; OR 0.33 (95% CI; 0.06-1.86). Diaphragmatic atrophy was observed in 17/53 cases, in three of extubation failure occurred. Children in the extubation failure group were younger: 2.0 months (IQR 0.81-183.0) vs. 3.0 months (IQR 0.10-48.0); p = 0.045. At baseline, pre-extubation and post-extubation there was no significant correlation between age and BSA on the one hand and dTF, Tdi- insp and Tdi-exp on the other hand. The ICC representing the level of inter-rater reliability between the two examiners performing the ultrasounds was 0.994 (95% CI 0.970-0.999). The ICC of the inter-rater reliability between the raters in 36 paired assessments was 0.983 (95% CI 0.974-0.990). CONCLUSION: There was no significant association between thickening fraction of the diaphragm and extubation success in ventilated children
Prehospital Management of Peripartum Neonatal Complications by Helicopter Emergency Medical Service in the South West of the Netherlands: An Observational Study
Objective: Emergency medical service (EMS) is responsible for prehospital care encompassing all ages, irrespective of injury cause or medical condition, which includes peripartum emergencies. When patients require care more advanced than the level provided by the national EMS protocol, an EMS physician-staffed Dutch helicopter emergency medical service (HEMS) may be dispatched. In the Netherlands in 2016, there were 21.434 planned home births guided by midwives alone without further obstetric assistance, accounting for 12.7% of all births that year. However, there are no clear data available thus far regarding neonates requiring emergency care with or without HEMS assistance. This article reviews neonates during our study period who received medical care after birth by HEMS. Methods: A retrospective chart review was performed including neonates born on the day of the dispatch between January 2012 and December 2017 who received additional medical care from the Rotterdam HEMS. Results: Fifty-two neonates received medical care by HEMS. The majority (73.1%) were full-term (Gestational age > 37 weeks). Home delivery was intended in 63.5%, 20% of whom experienced an uncomplicated delivery but had a poor start of life. The majority of unplanned deliveries (n = 17) were preterm (70.6%). Two were born by resuscitative hysterotomy; 1 survived in good neurologic condition, and the other died at the scene. Fifteen neonates (28.9%) required cardiopulmonary resuscitation; in 2 cases, no resuscitation was started on medical grounds, and 12 of the other 13 resuscitated neonates regained return of spontaneous circulation. In 33 (63.5%) of the neonates, respiratory interventions were required; 8 (15.4%) were intubated before transport. Death was confirmed in 5 (9.6%) neonates, all preterm. Conclusion: During the study period, 52 neonates required medical assistance by HEMS. The 5 infants who died were all preterm. In this cohort, adequate basic life support was implemented immediately after birth either by the attending midwife, EMS, or HEMS on arrival. This suggests that prehospital first responders know the basic skills of
