Characteristics, outcomes, and 30-day readmissions following pediatric extracorporeal membrane oxygenation in the United States: A Nationwide Readmissions Database study

OBJECTIVES

Extracorporeal membrane oxygenation (ECMO) is an increasingly used mode of critical care support for pediatric patients refractory to conventional therapy. We evaluated the characteristics, outcomes, and readmissions rates for pediatric ECMO in the United States.

METHODS

Data was extracted from the Nationwide Readmissions Database, a database designed to support national readmissions analyses, for patients aged 1-18 years undergoing ECMO between 2012-2018. Baseline demographics, comorbidities, and characteristics were identified using International Classification of Diseases codes.

RESULTS

Out of 897,117 index pediatric hospitalizations, 3706 patients underwent ECMO [median age 9 years (IQR 2,15); 51.6% males]. 2246 (60.6%) patients survived to hospital discharge, with a 30-day readmissions rate of 17% among survivors. Cardiac conditions associated with ECMO were congenital heart disease (25.3%), cardiogenic shock (23.6%), and congestive heart failure (16.2%). The common respiratory associations were sepsis (36.2%), pneumonia (35.6%), and asthma (15.4%). Patients who survived were more likely to have diagnoses of asthma, bronchiolitis, myocarditis, pneumonia, and sepsis. Acute kidney injury (51.5%), disseminated intravascular coagulation (22.5%), and surgical site bleeding (12.7%) were the commonly associated complications. The trend for yearly survival rates was not statistically significant (linear p-trend = 0.38).

CONCLUSIONS

Pediatric ECMO continues to be associated with notable mortality and complication rates. We did not observe a meaningful trend for the yearly survival rates over the study period, and over one-sixth of survivors were readmitted within 30-days. More research is needed to identify patients at high risk of mortality and readmissions, to help target resources more efficiently and improve survival.

Prenatal betamethasone does not affect glutamatergic or GABAergic neurogenesis in preterm newborns

Prenatal glucocorticoids (GCs) are routinely used for pregnant women in preterm labor to prevent respiratory distress syndrome and intraventricular hemorrhage in premature infants. However, the effect of antenatal GCs on neurogenesis in preterm neonates remains elusive. Herein, we hypothesized that prenatal GCs might suppress both glutamatergic and GABAergic neurogenesis in preterm rabbits and that this treatment would induce distinct changes in the expression of transcription factors regulating these developmental events. To test our hypotheses, we treated pregnant rabbits with betamethasone at E27 and E28, delivered the pups at E29 (term=32d), and assessed neurogenesis at birth and postnatal day 3. We quantified radial glia (Sox2(+)) and intermediate progenitor cells (Tbr2(+)) in the dorsal cortical subventricular zone to assess glutamatergic neuronal progenitors, and counted Nkx2.1(+) and Dlx2(+) cells in the ganglionic eminence to evaluate GABAergic neurogenesis. In addition, we assayed transcription factors regulating neurogenesis. We found that prenatal GCs did not affect the densities of radial glia and intermediate progenitors of glutamatergic or GABAergic neurons. The number of GABA(+) interneurons in the ganglionic eminence was similar between the prenatal GC-treated pups compared to untreated controls. Moreover, the mRNA expression of transcription factors, including Pax6, Ngn1/2, Emx1/2, Insm1, Dlx1, Nkx2.1, and Gsh2, were comparable between the two groups. However, there was a transient elevation in Mash1 protein in betamethasone-treated pups relative to controls at birth. These data suggest that prenatal GC treatment does not significantly impact the balance of glutamatergic and GABAergic neurogenesis in premature infants.

How we do it: acute management of subarachnoid hemorrhage

OBJECTIVES

Acute subarachnoid hemorrhage (SAH) is a neurological emergency with significant potential for long-term morbidity and mortality. We review our management of acute SAH and some of the evidence base supporting our practices.

METHODS

We reviewed our standardized and multi-disciplinary approach to the management of SAH.

RESULTS

Management of SAH treatment can be divided into acute, aneurysmal, waiting, and post-waiting phases. Acute issues upon presentation include hemodynamic and respiratory stability, prevention of rebleeding, and treatment of hydrocephalus. The aneurysm must then be secured through endovascular or microsurgical methods. Observation for signs and symptoms of vasospasm must be closely undertaken. Prevention of subsequent medical complications must also be undertaken. Weaning from cerebrospinal fluid diversion and possible shunting is the final step.

DISCUSSION

Standardized multi-modality management of rebleeding, hydrocephalus, aneurysmal obliteration, vasospasm, cerebral salt wasting, and other medical complications during these phases, is critical.
