Improved Outcomes

BACKGROUND: The purpose of this study was to compare the outcomes of infants with giant omphalocele (GO) born in two different epochs over two decades at a single institution. Specifically, it examined whether the utilization of selective pulmonary vasodilators and extracorporeal membrane oxygenator (ECMO) in the management of pulmonary hypertension in the second epoch were associated with improved outcomes. METHODS: The medical records of all patients diagnosed with GO at a large children’s hospital from January 1, 1996 to December 31, 2016 were reviewed and divided into two epochs. Patients were classified as having an isolated GO or GO with minor or major associated anomalies. GO was defined as a defect more than or equal to 5 cm in size and/or liver in the sac. RESULTS: During the study period, 59 infants with GO were identified. The duration of invasive mechanical ventilation was significantly shorter among the survivors from the second epoch (p = 0.03), with none greater than seven days. There were no significant differences in the outcomes of survival to NICU discharge and length of stay (LOS) between infants in the two epochs. CONCLUSIONS: Infants with GO who required invasive mechanical ventilation for more than seven days did not survive in the second epoch. Survival did not improve with uses of selective pulmonary vasodilators and ECMO. This information could be shared with families during prenatal and postnatal counselling to facilitate informed decision making regarding goals of care.

Background The use of extracorporeal membrane oxygenator (ECMO) support devices are associated with complications, including bleeding and thrombosis. Unfractionated heparin (UFH) is the gold standard anticoagulant in ECMO patients. Clinically, UFH is monitored through activated clotting time (ACT), activated partial thromboplastin time (aPTT), and anti–factor Xa assay. It is unknown which assay best predicts anticoagulation effects in adults. Objective To assess the correlation of UFH dosing and monitoring using an established protocol. Methods A pilot, prospective cohort, historically controlled study was conducted at a tertiary care hospital. Patients ≥18 years-old who received ECMO on the multifaceted anticoagulation protocol were included and compared with those on the conventional method of anticoagulation. The primary end point was to assess the correlation between UFH dose and different monitoring methods throughout 72 hours using the new protocol guided by ACT and anti–factor Xa assay. Results In each arm, 20 patients were enrolled. The study revealed that anti–factor Xa assay had the largest number of “strong” correlations 11/20 (55%), followed by both aPTT and aPTT ratio 10/20 (50%), and, finally, ACT 2/20 (10%). Concordance between anti–factor Xa assay and the other monitoring parameters in the prospective arm was generally low: 31% with aPTT ratio, 26% with ACT, and 23% with aPTT. Conclusion and Relevance The adaption of a multifaceted anticoagulation protocol using anti–factor Xa assay may provide a better prediction of heparin dosing in adults ECMO patients compared with the conventional ACT-based protocol. Further studies are needed to assess the safety and different monitoring modalities.

Objective: The aim was to evaluate the performance of a newly developed magnetically suspended centrifugal pump head intended for use as a ventricular assistance device with a newly developed extracorporeal membrane oxygenator setup. Methods: In an experimental setup, an extracorporeal membrane oxygenator circuit was established in three calves with a mean weight of 68.2 ± 2.0 kg. A magnetically levitated centrifugal pump was tested, along with a newly designed extracorporeal membrane oxygenator console, at three different flow ranges: (a) 0.0 to 5.2 L/min, (b) 0.0 to 7.1 L/min, and (c) 0.0 to 6.0 L/min. For each setup, the animals were supported by a circuit for 6 h. Blood samples were collected just before caridiopulmonary bypass (CPB) after 10 min on bypass and after 1, 2, 5, and 6 h of perfusion for hemolysis determination and biochemical tests. Values were recorded for blood pressure, mean flow, and pump rotational speed. Analysis of variance was used for repeated measurements. Results: Mean pump flows achieved during the three 6 h pump runs for the three pump heads studied were as follows: (a) flow range 0.0 to 5.2 L/min, 3.6 ± 1.5 L/min, (b) flow range 0.0 to 7.1 L/min, 4.9 ± 1.3 L/min, and (c) flow range 0.0 to 6.0 L/min, 3.8 ± 1.5 L/min. Blood trauma, evaluated by plasma hemoglobin and lactate dehydrogenase levels, did not help in detecting any significant hemolysis. Thrombocytes and white blood cell count profiles showed no significant differences between the groups at the end of the 6 h perfusion. At the end of testing, no clot deposition was found in the oxygenator, and there was no evidence of peripheral emboli. Conclusion: The results suggest that the newly developed magnetically suspended centrifugal pump head provides satisfactory hydrodynamic performance in an acute perfusion scenario without increasing hemolysis.
