Objective: To present our center’s experience with terminal extubation in 3 palliative critical care home transports from the Pediatric Cardiac Intensive Unit. Design: All cases were identified from our Cardiovascular intensive care unit ( CVICU). Patients were terminally ill children with no other surgical or medical option who were transported home between 2014 and 2018, for terminal extubation and end-of-life care according to their families’ wishes. Interventions: The patients were 7, 9 months, and 19 years; and they had very complex and chronic conditions. The families were approached by the CVICU staff during multidisciplinary meetings, where goals of care were established. Parental expectations were clarified, and palliative care team was involved, as well as home hospice was arranged pre transfer. The transfer process was discussed and all the needs were established. All patients had unstable medical conditions, with needs for transport for withdrawal of life support and death at home. Each case needed a highly trained team to support life while in transport. The need of these patients required coordination with home palliative care services, as well as community resources due to difficulty to get in their homes. Conclusions: Transportation of pediatric cardiac critical care patients for terminal extubation at home is a relatively infrequent practice. It is a feasible alternative for families seeking out of the hospital end-of-life care for their critically ill and technology dependent children. Our single-center experience supports the need for development of formal programs for end-of-life critical care transports.

Purpose Right atrial (RA) or intracardiac lines are commonly used for hemodynamic monitoring in children undergoing cardiac surgery. In some institutions, these lines are used as the preferred long-term access line due to concerns for catheter-associated blood stream infections (CABSI) and catheter-related venous thrombosis with central lines in other locations. However, the rates and risk factors for CABSI and other complications are not known for RA lines. We undertook this study to estimate CABSI rates for RA lines in comparison with central catheters of various types and locations and to evaluate the incidence of other complications associated with the use of RA lines. Methods After approval from the Institutional Review Board, a retrospective review of all patients undergoing cardiac surgery at Arkansas Children's Hospital between the dates of January 1, 2006 and December 31, 2011 was performed. Demographic data, clinical features, and outcomes were summarized on a per-patient level. Type, location of placement, and duration of all centrally placed catheters as well as associated complications were recorded. Central venous lines (CVL) used in our unit include peripherally inserted central catheters (PICC) lines, and antibiotic and heparin coated double or triple lumen lines placed in internal jugular (IJ), femoral (Fem), or RA positions. The data were analyzed using statistical software STATA/MP. Results A total of 2,736 central lines were used in 1,537 patients. Data on line duration, alteplase use, and percentage of lines developing CABSI are described in the study. Disease severity as assessed by risk-adjusted classification for congenital heart surgery (RACHS) score (p < 0.046), year of placement (p < 0.001), and line type adjusted for thrombolytic (alteplase) use are significantly associated with risk of any CABSI. Overall, IJ and RA lines had least risk of CABSI while PICC lines had the highest CABSI rates. RA lines are also associated with other medically significant complications. Conclusion The CABSI rates associated with RA lines are lower than those seen with PICC lines. However, RA line use is associated with other, potentially significant complications. RA lines may be used cautiously as long-term access lines in cardiac patients in whom it is important to preserve venous patency for future interventions.

Evaluate the impact of chronic cardiac care team (CCCT) on hospital course of patients, their families, and nursing staff. Retrospective observational study in children with hospital stay of ≥6 weeks in a pediatric cardiac intensive care unit (CICU) at a tertiary care children's hospital. Before and after care, survey of the nurses and patients family was also performed. The CCCT provided care for 68 patients of which 44 survived to discharge. Median age at admission was 19 days (range 0-20.6 years); 18 (26%) were admitted at birth. Cardiac diagnosis included single ventricle in 27, heart failure/cardiac transplantation in 37, others in 6. The CCCT was involved in follow-up for vitamin and endocrine deficiencies, updating immunization status, optimizing nutritional intake, growth parameters, assess feeding issues, and providing end-of-life discussions in all those who died. One year after implementation, 85% nurses indicated improved understanding of patient problems, 57% reported improved working relationship with families, and 87% reported improved team communication. Family survey indicated that implementation of the model led to significantly improved opinion of parents in their ability to participate in the plan of care (28% vs. 70%, P = 0.019) and better relationship with the CICU staff caring for their child (57% vs. 100%, P = 0.008). The CCCT provides a new team-based paradigm for improving continuity of care in chronic CICU patients by supplementing medical care and facilitates end-of-life discussions. The CCCT bridges communication gap between CICU staff and families.

Background: The clinical characteristics of patients with Aspergillus isolation while supported on extracorporeal membrane oxygenator (ECMO) remain unclear. Objectives: We present a case report of angioinvasive Aspergillus infection on an infant supported on ECMO and also investigate outcomes among patients with Aspergillus infection reported to the Extracorporeal Life Support Organization (ELSO) registry. Design: Case report and retrospective analysis of ELSO registry data set from 1985 to 2009. Setting: One hundred and seventy ECMO centers contributing data to the ELSO registry. Patients: Single case report and patients 0 to 90 years of age with Aspergillus infection requiring ECMO support as reported to the ELSO registry. Methods: Besides presenting details of our institutional case, we compared clinical characteristics and outcomes between pediatric and adult patients with Aspergillus isolation. Risk factors for in-hospital mortality were investigated. Kaplan-Meier estimates for freedom from death on ECMO for pediatric and adult patients were investigated. Measurements and Main Results: (a) we report a case with Aspergillus supported on ECMO, (b) the ELSO registry yielded 46 patients with 59% (n = 27) in the pediatric data set (≤20 years of age) and 41% (n = 19) in the adult data set (>20 years of age) with Aspergillus infection requiring ECMO support. Overall survival to hospital discharge was 30% (14/46) with 22% (6/27) in children as compared to 42% (8/18) in adults (P = .19). Table 1 shows a comparison of clinical characteristics between children and adults. The comparison between adults and pediatric groups differed significantly in age (P = .0001), more use of venoarterial ECMO in children (P = .028). The median age of pediatric group was 1.95 years (range 0-17.3 years) versus 30.2 years (range 22-60 years) among adults. Conclusions: Aspergillus infection/colonization is associated with a 70% overall mortality among patients supported on ECMO. The ELSO registry data confirms that Aspergillus infection among ECMO supported patients occurs often in hosts who do not have known immunodeficiencies. The case stresses the need for a high level of suspicion for Aspergillus infection in nonimproving lung disease in patients on ECMO support.

To investigate if the low dose (1 µg) ACTH stimulation test appropriately assesses adrenal responsiveness in neonates undergoing open-heart surgery requiring cardio-pulmonary bypass. In this retrospective study, adrenal axis response was assessed on the first post-operative day with the low-dose (1 µg) ACTH stimulation test. Age, gender, weight, RACHS category, inotrope score, and baseline and post-stimulation cortisol levels were collected. The association between basal serum cortisol levels and degree of response to the ACTH stimulation test was also investigated. Tertiary care referral center. Twenty-one neonates who underwent neonatal cardiac surgery on cardiopulmonary bypass and underwent an ACTH stimulation test. Interventions. Hydrocortisone 50 mg/m(2) bolus in four divided doses daily. Response to the low dose (1 µg) ACTH stimulation was assessed. All neonates with hemodynamic instability in the immediate post-operative period had low basal serum cortisol levels. The basal mean serum cortisol level for the 21 patients who underwent the low dose ACTH stimulation test was 7.3 µg/dL (median 2.2, range 0.7-42). The mean serum cortisol level increased after the ACTH stimulation test in the 21 patients to 39.6 µg/dL (median 38, range 79-17). The mean inotrope score in the first 24 hours after surgery was 24 (median 17.5, range 7-76.5) and decreased to 17 (median 14, range 5-52.3) 24-48 hours after surgery. At 48 hours post-surgery the mean arterial pressure in the groups with a serum cortisol increase after ACTH stimulation (50 µg/dL) was significantly different (P value 0.026). The low dose (1 µg) ACTH stimulation test is a valid test to assess adrenal responsiveness among neonates after open heart surgery requiring CPB. Traditionally used basal serum cortisol level cutoff of <20 µg/dL used to define relative adrenal insufficiency may not be applicable in neonates undergoing open heart surgery on CPB thus indicating the need for re-defining adrenal insufficiency in this patient population.
