RESUMO
OBJECTIVES: Children with CHD are at heightened risk of neurodevelopmental problems; however, the contribution of acute neurological events specifically linked to the perioperative period is unclear. AIMS: This secondary analysis aimed to quantify the incidence of acute neurological events in a UK paediatric cardiac surgery population, identify risk factors, and assess how acute neurological events impacted the early post-operative pathway. METHODS: Post-operative data were collected prospectively on 3090 consecutive cardiac surgeries between October 2015 and June 2017 in 5 centres. The primary outcome of analysis was acute neurological event, with secondary outcomes of 6-month survival and post-operative length of stay. Patient and procedure-related variables were described, and risk factors were statistically explored with logistic regression. RESULTS: Incidence of acute neurological events after paediatric cardiac surgery in our population occurred in 66 of 3090 (2.1%) consecutive cardiac operations. 52 events occurred with other morbidities including renal failure (21), re-operation (20), cardiac arrest (20), and extracorporeal life support (18). Independent risk factors for occurrence of acute neurological events were CHD complexity 1.9 (1.1-3.2), p = 0.025, longer operation times 2.7 (1.6-4.8), p < 0.0001, and urgent surgery 3.4 (1.8-6.3), p < 0.0001. Unadjusted comparison found that acute neurological event was linked to prolonged post-operative hospital stay (median 35 versus 9 days) and poorer 6-month survival (OR 13.0, 95% CI 7.2-23.8). CONCLUSION: Ascertainment of acute neurological events relates to local measurement policies and was rare in our population. The occurrence of acute neurological events remains a suitable post-operative metric to follow for quality assurance purposes.
RESUMO
AIM: The aim of this study was to assess the safety and efficacy of long-term milrinone therapy in children with acute decompensated heart failure due to dilated cardiomyopathy (DCM). METHODS: A single-centre retrospective study of all children ≤18 years with acute decompensated heart failure and DCM who received continuous long-term (≥7 consecutive days) intravenous milrinone between January 2008 and January 2022. RESULTS: The 47 patients had a median age of 3.3 months [interquartile range (IQR) 1.0-18.1], weight of 5.7 kg [IQR 4.3-10.1] and fractional shortening of 11.9% [±4.7]. Idiopathic DCM (n = 19) and myocarditis (n = 18) were the most common diagnoses. The median milrinone infusion duration was 27 days [IQR 10-50, range 7-290]. No adverse events necessitated milrinone termination. Nine patients required mechanical circulatory support. Median follow-up was 4.2 years [IQR 2.7-8.6]. On initial admission, four patients died, six were transplanted and 79% [37/47] were discharged home. The 18 readmissions resulted in five more deaths and four transplantations. Cardiac function recovered in 60% [28/47], as measured by normalised fractional shortening. CONCLUSION: Long-term intravenous milrinone is safe and effective in paediatric acute decompensated DCM. Combined with conventional heart failure therapies, it can act as a bridge to recovery and thereby potentially reduce the need for mechanical support or heart transplantation.

OBJECTIVE: Unplanned reintervention (uRE) is used as an indicator of patient morbidity and quality of care in pediatric cardiac surgery. We investigated associated factors and early mortality after uREs. METHODS: Morbidity data were prospectively collected in 5 UK centers between 2015 and 2017; uRE included surgical cardiac, interventional transcatheter cardiac, permanent pacemaker, and diaphragm plication procedures. Mortality (30-day and 6-month) in uRE/no-uRE patients was reported before and after matching. Predicted 30-day mortality was calculated using the Partial Risk Adjustment in Surgery score. RESULTS: A total of 3090 procedures (2861 patients) were included (median age, 228 days). There were 146 uREs, resulting in an uRE rate of 4.7%. Partial Risk Adjustment in Surgery score, 30-day mortality and 6-month mortality in uRE and no-uRE groups were 2.4% versus 1.3%, 8.9% versus 1%, and 17.1% versus 2.4%, respectively. After matching, mortality at 6 months remained higher in uRE compared with no-uRE (12.2% vs 1.4%; P = .02; 74 pairs). In the uRE group, 21 out of 25 deaths at 6 months occurred when at least 1 additional postoperative complication was present. In multivariable analysis, neonatal age (P = .002), low weight (P = .009), univentricular heart (P < .001), and arterial shunt (P < .001) were associated with increased risk of uRE, but Partial Risk Adjustment in Surgery score was not (only in univariable analysis). CONCLUSIONS: uREs are a relatively frequent complication after pediatric cardiac surgery and are associated with some patient characteristics, but not the Partial Risk Adjustment in Surgery risk score. Early mortality was higher after uRE, independent of preoperative factors, but linked to other postoperative complications.

OBJECTIVE: To compare national neonatal extracorporeal membrane oxygenation data and deaths from primary respiratory disorders of term neonates between the United Kingdom and the United States from 1999 to 2005. DESIGN: Cross-sectional study. SETTING: National data sets from the United Kingdom and the United States. PATIENTS: Neonatal extracorporeal membrane oxygenation patients submitted to the Extracorporeal Life Support Organization Registry and national birth and death registrations. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Meconium aspiration syndrome was the most common indication for extracorporeal membrane oxygenation in the United Kingdom: 50.6% vs. 25.8% in the United States (p < .001). Congenital diaphragmatic hernia was most common indication for extracorporeal membrane oxygenation in the United States: 30.7% vs. 15.4% in the United Kingdom (p < .001).Extracorporeal membrane oxygenation use was greater in the United States than the United Kingdom: rate ratio, 1.81 (95%, confidence interval, 1.64, 2.00). The extracorporeal membrane oxygenation rate decreased over time in the United States (p < .001) but was unchanged for all diagnoses in the United Kingdom (p = .49). The rates of extracorporeal membrane oxygenation use for meconium aspiration syndrome were equivalent in both countries: rate ratio, 0.92 (95% confidence interval, 0.80, 1.07) but greater in the United States for congenital diaphragmatic hernia: rate ratio, 3.60, (95% confidence interval, 2.82, 4.66) and persistent pulmonary hypertension newborn: rate ratio, 4.67 (95% confidence interval, 3.33, 6.74).National neonatal death rates included nonextracorporeal membrane oxygenation + extracorporeal membrane oxygenation death. Meconium aspiration syndrome deaths were equivalent overall between the two countries: rate ratio, 0.99 (95% confidence interval, 0.77, 1.29), but decreased in the United States (p < .001) although not in the United Kingdom (p = .17). Congenital diaphragmatic hernia deaths were more prevalent in the United Kingdom than in the United States: rate ratio, 1.57 (95% confidence interval, 1.34, 1.84). CONCLUSIONS: Extracorporeal membrane oxygenation is used more often in the United States: clinicians seem less willing to offer extracorporeal membrane oxygenation for persistent pulmonary hypertension of the newborn and congenital diaphragmatic hernia in the United Kingdom. In contrast to the United States, no reduction in either extracorporeal membrane oxygenation use or death due to meconium aspiration syndrome was observed in the United Kingdom. Early transfer to a tertiary center is recommended for term neonates with respiratory failure.

In this randomized, controlled multi-site study, the pacifier-activated-lullaby system (PAL) was used with 68 premature infants. Dependent variables were (a) total number of days prior to nipple feeding, (b) days of nipple feeding, (c) discharge weight, and (d) overall weight gain. Independent variables included contingent music reinforcement for non-nutritive sucking for PAL intervention at 32 vs. 34 vs. 36 weeks adjusted gestational age (AGA), with each age group subdivided into three trial conditions: control consisting of no PAL used vs. one 15-minute PAL trial vs. three 15-minute PAL trials. At 34 weeks, PAL trials significantly shortened gavage feeding length, and three trials were significantly better than one trial. At 32 weeks, PAL trials lengthened gavage feeding. Female infants learned to nipple feed significantly faster than male infants. It was noted that PAL babies went home sooner after beginning to nipple feed, a trend that was not statistically significant.

OBJECTIVE: Case reports of two patients with unusually late initial presentation of chronic granulomatous disease with fulminant Aspergillus pneumonia. DATA SOURCES AND EXTRACTION: Medical notes; retrospective study. STUDY SELECTION: Identical pattern of clinical presentation in two patients referred for support with extracorporeal membrane oxygenation (ECMO). Our Institutional Review Board waived the need for consent. DATA SYNTHESIS: Two school-aged boys presented with features of, and were initially treated, for community-acquired pneumonia. However, the disease course was rapidly progressive to fulminant respiratory failure and because both failed conventional intensive care management, they were referred to ECMO support. Although both died of evolving multiorgan failure, ECMO support allowed open lung biopsy leading to diagnosis of invasive Aspergillus pneumonia and chronic granulomatous disease. CONCLUSIONS: Failure of adequate therapy for acute community-acquired pneumonia and rapid progression to respiratory failure should lead to the possibility of fungal etiology. Congenital immunodeficiency may present for the first time late in life, so acute invasive pulmonary aspergillosis in the absence of known risk factors should lead to consideration of chronic granulomatous disease regardless of patient age.

The purpose of this study was to examine different protocols with regard to the presentation of music stimuli and compare gender differential reactions to those stimuli. Subjects for this study (N = 63) were premature infants in the Neonatal Intensive Care Unit (NICU) between the gestational ages of 28 and 33 weeks. Half of the experimental infants listened to 20 mins of lullaby music (female voice with orchestral background) on 2 days followed by 20 mins of classical music (Mozart string music) on 2 days. The other half listened to the same music in the reverse order. One quarter of the males and one quarter of the females listened to music presented at an average of 65 dB, one quarter at an average of 70 dB, one quarter at an average of 75 dB, and one quarter did not listen to any music and served as control subjects. Head circumference data were collected four times by the researcher: (a) upon receipt of parental consent, (b) on the first day of music presentation (1 week after consent), (c) on the last day of music presentation, and (d) 1 week after music presentation. Physiological data (heart rate, respiratory rate, oxygen saturation) were recorded by the researcher at 2-minute intervals starting 4 minutes prior to and ending 4 minutes after music presentation. There was a significant difference (p < .0001) in average daily head growth across time, but this seems unrelated to the music condition as the same curvilinear trend (larger gain during days of treatment, smaller gain during baseline before and after treatment) was noted for control infants who did not listen to music. Results indicate a significant (p = .002), but biologically unimportant, decrease in heart rate over the course of data collection. No differences due to gender were noted.

OBJECTIVE: Given excellent 30-day survival for pediatric cardiac surgery, other outcome measures are important. We aimed to study important early postoperative morbidities selected by stakeholders following a rigorous and evidenced-based process, with a view to identifying potential risk factors. METHODS: The incidence of selected morbidities was prospectively measured for 3090 consecutive pediatric cardiac surgical admissions in 5 UK centers between October 2015 and June 2017. The relationship between the candidate risk factors and the incidence of morbidities was explored using multiple regressions. Patient survival, a secondary outcome, was checked at 6 months. RESULTS: A total of 675 (21.8%) procedure episodes led to at least 1 of the following: acute neurologic event, unplanned reoperation, feeding problems, renal replacement therapy, major adverse events, extracorporeal life support, necrotizing enterocolitis, surgical infection, or prolonged pleural effusion. The highest adjusted odds ratio of morbidity was in neonates compared with children, 5.26 (95% confidence interval, 3.90-7.06), and complex heart diseases (eg, hypoplastic left heart), 2.14 (95% confidence interval, 1.41-3.24) compared with low complexity (eg, atrial septal defect, P < .001 for all). Patients with any selected morbidity had a 6-month survival of 88.2% (95% confidence interval, 85.4-90.6) compared with 99.3% (95% confidence interval, 98.9-99.6) with no defined morbidity (P < .001). CONCLUSIONS: Evaluation of postoperative morbidity provides important information over and above 30-day survival and should become a focus for audit and quality improvement. Our results have been used to initiate UK-based audit for 5 of these 9 morbidities, co-develop software for local monitoring of these morbidities, and parent information about these morbidities.

OBJECTIVES: Given the current excellent early mortality rates for paediatric cardiac surgery, stakeholders believe that this important safety outcome should be supplemented by a wider range of measures. Our objectives were to prospectively measure the incidence of morbidities following paediatric cardiac surgery and to evaluate their clinical and health-economic impact over 6 months. DESIGN: The design was a prospective, multicentre, multidisciplinary mixed methods study. SETTING: The setting was 5 of the 10 paediatric cardiac surgery centres in the UK with 21 months recruitment. PARTICIPANTS: Included were 3090 paediatric cardiac surgeries, of which 666 patients were recruited to an impact substudy. RESULTS: Families and clinicians prioritised:Acute neurological event, unplanned re-intervention, feeding problems, renal replacement therapy, major adverse events, extracorporeal life support, necrotising enterocolitis, postsurgical infection and prolonged pleural effusion or chylothorax.Among 3090 consecutive surgeries, there were 675 (21.8%) with at least one of these morbidities. Independent risk factors for morbidity included neonatal age, complex heart disease and prolonged cardiopulmonary bypass (p<0.001). Among patients with morbidity, 6-month survival was 88.2% (95% CI 85.4 to 90.6) compared with 99.3% (95% CI 98.9 to 99.6) with none of the morbidities (p<0.001). The impact substudy in 340 children with morbidity and 326 control children with no morbidity indicated that morbidity-related impairment in quality of life improved between 6 weeks and 6 months. When compared with children with no morbidities, those with morbidity experienced a median of 13 (95% CI 10.2 to 15.8, p<0.001) fewer days at home by 6 months, and an adjusted incremental cost of £21 292 (95% CI £17 694 to £32 423, p<0.001). CONCLUSIONS: Evaluation of postoperative morbidity is more complicated than measuring early mortality. However, tracking morbidity after paediatric cardiac surgery over 6 months offers stakeholders important data that are of value to parents and will be useful in driving future quality improvement.

BACKGROUND: Although mechanical circulatory support might not increase the number of adults surviving to transplantation, because of the shortage of donor organs, the situation might be different for children. Our aim was to assess the effect of mechanical assist devices to bridge children with end-stage cardiomyopathy to heart transplantation. METHODS: A 5-year retrospective review was undertaken with data from the UK paediatric transplant programme and from bridging to transplant done at two paediatric transplant centres in the UK. FINDINGS: Between Jan 1, 1998 and Dec 31, 2002, 22 children with end-stage cardiomyopathy, median age 5.7 years (range 1.2-17), were supported by a mechanical assist device as a bridge to first heart transplantation, with a 77% survival rate to hospital discharge. Nine were supported by a paracorporeal ventricular assist device, six received transplantation, five survived to discharge (55%), with one late death. 13 were supported by extra-corporeal membrane oxygenation, and 12 were transplanted and survived to discharge (92%) with one late death. With urgent listing, the median waiting time for a heart was 7.5 days (range 1.5-22 days). The correlation between the proportion of patients bridged to transplantation and the proportion of patients dying while on the transplant waiting list was r=-0.93, p=0.02. INTERPRETATION: Our findings lend support to the hypothesis that a national mechanical assist programme to bridge children to transplantation can minimise the number dying while on the heart transplant waiting list. In the context of urgent listing and a short waiting time, extra-corporeal membrane oxygenation seems to provide the safest form of support.

OBJECTIVES: Internationally, the number of donors for cardiac transplantation has remained static, while the number of patients requiring transplantation for congenital heart disease (CHD) has increased. Although the availability of mechanical circulatory support (MCS) may increase the number of transplants performed by reducing deaths while waiting, it may also lead to increased morbidity post-transplantation. We sought to assess the impact of mechanical support on post-transplant outcomes in a single centre. METHODS: We assessed the outcomes of paediatric (age ≤16 years) heart transplantation in a single unit in the era of mechanical support (1998-2012) by retrospective cohort study. Outcomes before (1998-2005) and after (2005-2012) the routine use of the Berlin Heart EXCOR device were contrasted. RESULTS: A total of 167 patients underwent heart transplantation during this period. The diagnosis was dilated cardiomyopathy in 61.7%, two-ventricle CHD in 11.4%, single ventricle CHD in 16.8% and miscellaneous in 10.1%. Sixty-nine (41%) were bridged to transplant by mechanical support; with extracorporeal membrane oxygenation in 19 (28%), ventricular assist device in 40 (58%) and a combination in 10 (14.0%). Post-transplant mortality at 30 days was significantly greater in those supported by MCS than without (7 vs 1%, P < 0.05), and a greater proportion of patients had neurological (23 vs 8%, P < 0.01) and major respiratory sequelae (20 vs 4%, P < 0.001). There was no significant increase in the need for post-transplant mechanical support (10 vs 6%, P = 0.3) in those supported prior to transplant. The number of transplants performed increased from 67 in 1998-2005 to 100 in the most recent era (2005-2012), and an increased proportion of these patients have been supported mechanically prior to transplantation (51 vs 27%, P < 0.01). CONCLUSION: Along with strategies to increase donor utilization, MCS has allowed an increase in cardiac transplant activity at the expense of a higher early mortality and morbidity.

BACKGROUND: Bloodstream infections from central venous catheters (CVC-BSIs) increase morbidity and costs in intensive care units (ICUs). Substantial reductions in CVC-BSI rates have been reported using a combination of technical and non-technical interventions. METHODS: We conducted a 2-year, four-cluster, stepped non-randomised study of technical and non-technical (behavioural) interventions to prevent CVC-BSIs in adult and paediatric ICUs in England. Random-effects Poisson regression modelling was used to compare infection rates. A sample of ICUs participated in data verification. RESULTS: Of 223 ICUs in England, 215 (196 adult, 19 paediatric) submitted data on 2479 of 2787 possible months and 147 (66%) provided complete data. The exposure rate was 438 887 (404 252 adult and 34 635 paediatric) CVC-patient days. Over 20 months, 1092 CVC-BSIs were reported. Of these, 884 (81%) were ICU acquired. For adult ICUs, the mean CVC-BSI rate decreased over 20 months from 3.7 in the first cluster to 1.48 CVC-BSIs/1000 CVC-patient days (p<0.0001) for all clusters combined, and for paediatric ICUs from 5.65 to 2.89 (p=0.625). The trend for infection rate reduction did not accelerate following interventions training. CVC utilisation rates remained stable. Pre-ICU infections declined in parallel with ICU-acquired infections. Criterion-referenced case note review showed high agreement between adjudicators (κ 0.706) but wide variation in blood culture sampling rates and CVC utilisation. Generic infection control practices varied widely. CONCLUSIONS: The marked reduction in CVC-BSI rates in English ICUs found in this study is likely part of a wider secular trend for a system-wide improvement in healthcare-associated infections. Opportunities exist for greater harmonisation of infection control practices. Future studies should investigate causal mechanisms and contextual factors influencing the impact of interventions directed at improving patient care.

BACKGROUND: Mechanical circulatory support (MCS) is used to support children with end-stage heart failure to heart transplant. METHODS: This was a retrospective cohort study of 7 years' experience with the Berlin Heart (BH) EXCOR (Berlin Heart AG, Berlin Germany) paracorporeal ventricular assist device (VAD) in 2 United Kingdom (UK) pediatric heart transplant centers and the effect of this program on the UK pediatric heart transplant service. RESULTS: Of 102 children who received BH support, 84% survived to transplant or BH explant and 81% survived to discharge. Neither age nor duration of support influenced outcome. Stroke, ongoing requirement for ventilation while on BH, and diagnosis other than dilated cardiomyopathy were the only independent mortality risk factors. Children who weighed < 20 kg had significantly (p = 0.03) longer support times than bigger children. The number of children treated with a BH increased over time (p = 0.01). Currently > 50% of pediatric heart transplants are bridged with a BH; however, pediatric transplants per year have not increased significantly (p = 0.07) CONCLUSIONS: BH use in the UK has allowed significant increases in the number of children with end-stage heart failure who can be successfully bridged to transplant and the length of time they can be supported. The total number of transplants has not increased.

OBJECTIVES: Mechanical circulatory support (MCS) may be required after orthotopic heart transplantation (OHTx) in children for the treatment of failure or rejection. We review the incidence and outcomes of post-transplant MCS in our institution. METHODS: MCS was classified as early (<1 month since transplant) or late (>1 month since transplant) and the support offered was either veno-arterial extra-corporeal membrane oxygenation (VA-ECMO) or a ventricular assist device (VAD). From 2003 to the present, 100 children (<16 years) underwent OHTx. Fifteen (15%) had 17 episodes of MCS. MCS was instituted early in 10 and late in seven episodes. Two children required two episodes of support. VA-ECMO was used in 12 episodes (71%). Two children required VAD support alone (12%). In three (17%) episodes ECMO was subsequently converted from VAD. RESULTS: Among 10 children with early failure, eight were successfully weaned from support with recovery of graft function. In the late failure group, three of six patients died. All but four patients underwent re-transplantation with no perioperative deaths. Overall survival to discharge was 66%. The early failure group shows a better survival rate to hospital discharge compared with the late failure group (78 vs 50%; P < 0.0001). CONCLUSIONS: The incidence of post-transplant MCS for graft failure in our patients was 15%. Early graft failure has a better outcome than late failure. Re-transplantation has good mid-term outcomes in children. A stepwise approach with a multimodality MCS strategy improves survival in this group of patients.

An 8-month-old boy with acute myocarditis was mechanically supported with the Berlin Heart EXCOR biventricular assist device. Signs of myocardial recovery were not apparent until 40 days from presentation and ventricular function continued to improve with device removal possible after 120 days of support. He had normal cardiac function 3 months after device removal. Recovery from myocarditis in infants can take much longer than previously recognized and an extended wait for recovery is possible with the Berlin Heart.

Mechanical cardiac assistance for infants and children may be accomplished using extracorporeal membrane oxygenation or ventricular assist device support, and are now well established as a bridge to cardiac transplantation or recovery in biventricular hearts, usually in the setting of low cardiac output states due to cardiomyopathy or acute myocarditis. Ventricular assist device support remains less well described in the setting of single ventricle physiology. We report the case of a 3-year-old girl who developed severe right ventricular failure 2 years after cavopulmonary shunt after an initial Stage I Norwood operation for hypoplastic left heart syndrome. She was successfully supported to cardiac transplantation using a single chamber Berlin Heart EXCOR ventricular assist device using right ventricular apex and aortic cannulation and is now well at home 10 months after transplant.

BACKGROUND: Mechanical support as a bridge to cardiac transplantation in children is an accepted treatment. With improved devices and increasing experience, the length of time that children can be supported has increased. Donor organs remain scarce and there is significant associated morbidity. METHODS: Retrospective review of all children offered mechanical support as a bridge to heart transplant over 10 years in one of the two UK pediatric heart transplant centers. Outcomes during the years 1998 to 2002 were compared with outcomes during the years 2003 to 2007. RESULTS: Forty children in 41 separate patient episodes received mechanical support as a bridge to transplantation or, in 1 case, to recovery. Survival to transplant or recovery was achieved in 29 of 41 (71%); 26 of 40 children (63%) survived to hospital discharge. Devices used were extracorporeal membrane oxygenation (ECMO), the Medos HIAA, the Berlin Heart (from November 2005) and the Levitronix ventricular assist device (VAD) from 2007. All 3 children supported with the Levitronix survived to transplant (median duration of support 10 days). Ten of 13 children (77%) supported by the Berlin Heart survived to transplant or recovery (median duration of support 44 days). Four of 7 (57%) children supported using the Medos device survived to transplant (median duration of support 7 days). Neurologic events were the most common cause of death in both eras (1998 to 2002 and 2003 to 2008). CONCLUSIONS: Waiting times to pediatric cardiac transplant in the UK have increased. The Berlin Heart allows children to be bridged to transplant over long periods. Neurologic morbidity remains as a major concern.
