Critical incidents in paediatric critical care: who is at risk?

We evaluated the characteristics of children for whom critical incidents (CIs) were reported by performing prospective collection of patient data and retrospective review of reported CIs in a multidisciplinary neonatal-paediatric intensive care unit of a tertiary care university children's hospital. A period of 1year was analysed (January to December 2007; 1,251 admissions). CIs comprised adverse events (actual patient injury), as well as near-misses. The report form of critical incidents was web-based and reporting was voluntary, anonymous and non-punitive. The severity of all CIs was divided into minor, moderate and major. Patients with and without CIs were compared regarding the following characteristics: Paediatric Index of Mortality (PIM2), duration of mechanical ventilation, length of stay in the intensive care, admission mode (surgery, cardiopulmonary bypass, cardiac/non-cardiac unit), age and sex. There were 360 CI reports (83 per 1,000 patient days; 13% major, 26% moderate, 61% minor severity). Of these, 310 CIs could be assigned to 198 specific patients. In the univariate analysis, patient-related risk factors for CIs were higher PIM2 score (p < 0.0001), increased length of stay (p < 0.0001), mechanical ventilation (p < 0.0001), increased ventilator days (p < 0.0001), male gender (p = 0.022) and young age (p < 0.0001). Using a logistic regression model, mechanical ventilation (p < 0.0001), male gender (p = 0.034) and length of stay (p < 0.0001) continued to be associated with the occurrence of CIs. Conclusion CIs often occur in paediatric intensive care. Among the patient-related factors, male gender, mechanical ventilation, and length of stay are independently associated with CIs. Already known at admission to intensive care are male gender and, usually, requirement for mechanical ventilation. Improved knowledge of the risk factors for CIs could help to minimize their frequency and thus improve quality of car

Impact of Chest X-Ray Before Discharge in Asymptomatic Children After Cardiac Surgery—Prospective Evaluation

In many paediatric cardiac units chest radiographs are performed routinely before discharge after cardiac surgery. These radiographs contribute to radiation exposure. To evaluate the diagnostic impact of routine chest X-rays before discharge in children undergoing open heart surgery and to analyze certain risk factors predicting pathologic findings. This was a prospective (6months) single-centre observational clinical study. One hundred twenty-eight consecutive children undergoing heart surgery underwent biplane chest X-ray at a mean of 13days after surgery. Pathologic findings on chest X-rays were defined as infiltrate, atelectasis, pleural effusion, pneumothorax, or signs of fluid overload. One hundred nine asymptomatic children were included in the final analysis. Risk factors, such as age, corrective versus palliative surgery, reoperation, sternotomy versus lateral thoracotomy, and relevant pulmonary events during postoperative paediatric intensive care unit (PICU) stay, were analysed. In only 5.5% (6 of 109) of these asymptomatic patients were pathologic findings on routine chest X-ray before discharge found. In only three of these cases (50%), subsequent noninvasive medical intervention (increasing diuretics) was needed. All six patients had relevant pulmonary events during their PICU stay. Risk factor analysis showed only pulmonary complications during PICU stay to be significantly associated (p=0.005) with pathologic X-ray findings. Routine chest radiographs before discharge after cardiac surgery can be omitted in asymptomatic children with an uneventful and straightforward perioperative course. Chest radiographs before discharge are warrantable if pulmonary complications did occur during their PICU stay, as this is a risk factor for pathologic findings in chest X-rays before discharg

Balloon angioplasty and stent implantation within 30 days postcongenital heart surgery (CHS) in children

OBJECTIVES This study aims to assess balloon angioplasty (BAP) and stent implantation (SI) procedures early after congenital heart surgery (CHS) in children. BACKGROUND These interventions are considered potential high-risk procedures and often avoided or postponed. METHODS This is a retrospective, single centre study of all BAP and SI procedures within 30 days after CHS (01/2001 until 01/2021). RESULTS A total of 127 (96 SI, 31 BAP) procedures were performed in 104 patients at median 6.5 days (interquartile range: 1-15) after CHS. Balloon-to-stenosis ratio and balloon-to-reference vessel ratio were significantly smaller compared to stent-to-stenosis ratio and stent-to-reference vessel ratio (p < .001 and p = .005). There was a greater rise in absolute vessel diameter, greater rise in vessel diameter in relation to the stenosis and vessel diameter in relation to the reference vessel with SI (p < .001, p = .01, and p < .001). Up to 94% SIs fulfilled both success criteria (increase of vessel diameter ≥50% of minimal vessel diameter or achievement ≥75% of the reference vessel diameter). Major adverse events were more frequent in the BAP group (p = .05). Intraprocedural complications were 5/31 (16%) in the BAP group and 13/96 (13%) in the SI group (p = .77). CONCLUSION BAP and SI procedures within 30 days post-CHS can be performed safely, with a greater stent-to-stenosis ratio and a greater rise in vessel diameter with stent implantation

Extracorporeal membrane oxygenation support in pediatrics

Extracorporeal membrane oxygenation (ECMO) is a general term that describes the short- or long-term support of the heart and/or lungs in neonates, children and adults. Due to favorable results and a steady decline in absolute contraindications, its use is increasing worldwide. Indications in children differ from those in adults. The ECMO circuit as well as cannulation strategies also are individualized, considering their implications in children. The aim of this article is to review the clinical indications, different circuits, and cannulation strategies for ECMO. We also present our institutional experience with 92 pediatric ECMO patients (34 neonates, 58 pediatric) with the majority (80%) of veno-arterial placements between 2014 until 2018. We further to also highlight ECMO use in the setting of cardiac arrest [extracorporeal cardiopulmonary resuscitation (CPR) or eCPR]

Risk factor analysis for a complicated postoperative course after neonatal arterial switch operation: The role of troponin T

OBJECTIVE: To find risk factors for a complicated early postoperative course after arterial switch operation (ASO) in neonates with d-transposition of the great arteries (dTGA). In addition to anatomical and surgical parameters, the predictive value of early postoperative troponin T (TnT) values in correlation to the early postoperative course after ASO is analyzed. METHODS: Seventy-nine neonates (57 (72%) male) with simple dTGA treated by ASO between 2009 and 2016 were included in the analysis. A complicated early postoperative course (30 days) was defined by one of the following criteria: (A) moderate to severe cardiac dysfunction without rhythm disturbances, (B) rhythm disturbances causing hemodynamic instability with the need for medical treatment, (C) signs for ischemia in ECG, (D) need for surgical or catheter interventional reinterventions other than diagnostic, or (E) other reasons. RESULTS: Forty of 79 patients (51%) showed a complicated early postoperative course after ASO, with 2 patients dying after 13 and 16 days. Patients with a complicated early postoperative course had a longer PICU stay (P < .001), needed longer mechanical ventilator support (P = .001) and longer inotropic support (P = .03), and more reinterventions (surgical or catheter interventional) were necessary (P = .001). Only the presence of a VSD (P = .001) and longer surgery duration (P = .026) were associated to a complicated postoperative course. TnT values only showed a trend toward higher values in patients with a complicated postoperative course (P = .06). A secondary rise in TnT was seen in 10 patients, ranging from 11.6% to 410.2%, of whom 7 could be classified in the complicated postoperative group. CONCLUSIONS: The postoperative course after ASO in dTGA neonates is influenced by other cardiac comorbidities like a VSD with the need for surgical treatment, influencing surgery duration. Postoperative higher TnT values reflect a longer and more vulnerable intraoperative course with limited predictive value on the early postoperative course

Plasma proendothelin-1 as an early marker of bronchopulmonary dysplasia

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a common complication in preterm infants. Clinical prediction of BPD at an early stage in life is difficult. Plasma proendothelin-1 (CT-proET-1) is a lung injury biomarker in pulmonary hypertension and respiratory distress. OBJECTIVE: To assess the prognostic ability of CT-proET-1 in BPD. METHODS: In 227 prospectively enrolled preterm infants born at <32 weeks gestational age (GA), plasma CT-proET-1 was measured at birth, day of life (DOL) 2, 3, 6 and 28, and at 36 weeks postmenstrual age (PMA). BPD was defined as mild in infants requiring supplemental oxygen at DOL 28 and moderate/severe in those requiring it at 36 weeks PMA. RESULTS: The predictive ability of CT-proET-1 for any BPD was poor at birth [area under the ROC curve (AUC) 0.654, 95% CI 0.494-0.814], moderate at DOL 2 and 3 (AUC 0.769, 95% CI 0.666-0.872) and excellent at DOL 6 (AUC 0.918, 95% CI 0.840-0.995). Multivariable regression analysis revealed that CT-proET-1 levels at DOL 2, 3, 6 and 28 were strongly related to the duration of oxygen supplementation, independently of GA and the duration of respiratory support. CONCLUSIONS: CT-proET-1 is a novel promising biomarker for predicting the development of BPD in preterm infants when measured at the end of the first week of life
