Background:
The best transfusion approach for CHD surgery is controversial. Studies suggest two strategies: liberal (haemoglobin ≤ 9.5 g/dL) and restrictive (waiting for transfusion until haemoglobin ≤ 7.0 g/dL if the patient is stable). Here we compare liberal and restrictive transfusion in post-operative CHD patients in a cardiac intensive care unit.
Methods:Retrospective analysis was conducted on CHD patients who received liberal transfusion (2019–2021, n=53) and restrictive transfusion (2021–2022, n=43).
Results:The two groups were similar in terms of age, gender, Paediatric Risk of Mortality-3 score, Paediatric Logistic Organ Dysfunction-2 score, Risk Adjustment for Congenital Heart Surgery-1 score, cardiopulmonary bypass time, vasoactive inotropic score, total fluid balance, mechanical ventilation duration, length of cardiac intensive care unit stay, and mortality. The liberal transfusion group had a higher pre-operative haemoglobin level than the restrictive group (p < 0.05), with no differences in pre-operative anaemia. Regarding the minimum and maximum post-operative haemoglobin levels during a cardiac intensive care unit stay, the liberal group had higher haemoglobin levels in both cases (p<0.01 and p=0.019, respectively). The number of red blood cell transfusions received by the liberal group was higher than that of the restrictive group (p < 0.001). There were no differences between the two groups regarding lactate levels at the time of and after red blood cell transfusion. The incidence of bleeding, re-operation, acute kidney injury, dialysis, sepsis, and systemic inflammatory response syndrome was similar.
Conclusions:Restrictive transfusion may be preferable over liberal transfusion. Achieving similar outcomes with restrictive transfusions may provide promising evidence for future studies.

Introduction
Understanding parents’ communication preferences and how parental and child characteristics impact satisfaction with communication is vital to mitigate communication challenges in the cardiac ICU.
MethodsThis cross-sectional survey was conducted from January 2019 to March 2020 in a paediatric cardiac ICU with parents of patients admitted for at least two weeks. Family satisfaction with communication with the medical team was measured using the Communication Assessment Tool for Team settings. Clinical characteristics were collected via Epic, Pediatric Cardiac Critical Care Consortium local entry and Society for Thoracic Surgeons Congenital Heart Surgery Databases. Associations between communication score and parental mood, stress, perceptions of clinical care, and demographic characteristics along with patient demographic and clinical characteristics were examined. Multivariable ordinal models were conducted with characteristics significant in bivariate analysis.
ResultsIn total, 93 parents of 84 patients (86% of approached) completed surveys. Parents were 63% female and 70% White. Seventy per cent of patients were <6 months old at admission, 25% had an extracardiac abnormality, and 80% had a cardiac surgery this admission. Parents of children with higher pre-surgical risk of mortality scores (OR 2.875; 95%CI 1.076–7.678), presence of surgical complications (72 [63.0, 75.0] vs. 64 [95%CI 54.6, 73] (p = 0.0247)), and greater satisfaction with care in the ICU (r = 0.93922; p < 0.0001) had significantly higher communication scores.
ConclusionThese findings can prepare providers for scenarios with higher risk for communication challenges and demonstrate the need for further investigation into interventions that reduce parental anxiety and improve communication for patients with unexpected clinical trajectories

Objective
The objective of the study was to identify incidence, aetiology, and outcomes of extubation failure in infants with shunt-dependent pulmonary blood flow at a single tertiary care, academic children's hospital. The second objective of this study was to determine the haemodynamic effects of transition of positive pressure ventilation to spontaneous breathing in infants with extubation failure.
Patients and methodsExtubation failure for our study was defined as the need for positive pressure ventilation within 96 hours after extubation. We collected demographics, pre-operative, intra-operative, post-operative, and peri-extubation data in a retrospective, observational format in patients who underwent a modified Blalock–Taussig shunt between January, 2005 and March, 2011. Infants undergoing Norwood operation or Damus–Kaye–Stansel with modified Blalock–Taussig shunt were excluded from the study. The cardiorespiratory variables collected before extubation and immediately after extubation included heart rate, respiratory rate, mean arterial blood pressure, central venous pressures, near infrared spectroscopy, oxygen saturations, and lactate levels. Clinical outcomes evaluated included the success or failure of extubation, cardiovascular intensive care unit length of stay, hospital length of stay, and mortality. Descriptive and univariate statistics were utilised to compare groups with extubation failure and extubation success.
ResultsOf the 55 eligible patients during the study period, extubation failure occurred in 27% (15/55) of the patients. Of the 15 patients with extubation failure, 10 patients needed reintubation and five patients received continuous positive pressure ventilation without getting reintubated. There were three patients who had extubation failure in the first 2 hours after extubation, nine patients in the 2–24-hour period, and three patients in the 24–96-hour period. In all, eight patients were extubated in the second attempt after the first extubation failure, with a median duration of mechanical ventilation of 2 days (1 day, 6 days). The median age of patients at extubation was 19 days (12 days, 22 days) and median weight of patients was 3.6 kg (3.02 kg, 4.26 kg). In all, 38% (21/55) of the patients were intubated before surgery. The most common risk factors for failed extubation were lung disease in 46% (7/15), cardiac dysfunction in 26% (4/15), diaphragmatic paralysis in 13% (2/15), airway oedema in 6% (1/15), and vocal cord paralysis in 6% (1/15). The median duration of mechanical ventilation was 4 days (1 day, 10.5 days), median cardiovascular intensive care unit length of stay was 11 days (6.5 days, 23.5 days), and the median hospital length of stay was 30 days (14 days, 48 days). The overall mortality at the time of hospital discharge was 7%.
ConclusionsExtubation failure in infants with shunt-dependent pulmonary blood flow and univentricular physiology is high and aetiology is diverse. Cardiopulmonary effects of removal of positive pressure ventilation are more pronounced in children with extubation failure and include escalation in the need for oxygen requirement and increase in mean arterial blood pressure. The majority of extubation failures in this select patient population occurs in the first 24 hours. Extubation failure in these patients is not associated with increased hospital length of stay or mortality.
