RESUMO

Aim Determine the seasonal incidence of hospital Respiratory Syncytial Virus (RSV) bronchiolitis and explore the variables associated with admission to ward versus the Paediatric Intensive Care Unit (PICU). Method Retrospective case-control study. Children, aged ≤2 years, between November and March, over a 3 year period with a positive RSV nasopharyngeal aspirate test. Results A total of 557 children were included; 19% (n=106) required PICU admission. Children admitted to the PICU were younger in age, median (IQR) 6.93 (3.96, 11.89) weeks compared to children who remained on the wards 11.00 (5.86, 24.14) weeks. Being underweight at the point of admission (adjusted odds ratio 3.15, 95% 1.46, 6.70, p=0.003) was associated with a PICU admission. Conclusion Number of RSV bronchiolitis hospitalisations are increasing each year. Age, weight and the use of HFNC were independent predictors for PICU admission.

RESUMO

The development of Leadless cardiac pacemakers avoids the inherent complications that may occur secondary to lead insertion. A large number of devices have been inserted in adult patients although data in pediatric patients are lacking. We aimed to assess our experience with the Leadless device in the pediatric population. We performed a retrospective study on all pediatric patients who underwent insertion of a Leadless pacemaker in our center. Data were collected for demographic, procedural, and outcome variables. Nine patients with a median (IQR) age and weight of 13 (12-14) years and 37 (31-50) kg, respectively, were enrolled. The median (IQR) procedural time was 62 (60-65) min with insertion thresholds of 0.5 (0.35-1) Volts at 0.24 ms. All devices were successfully inserted without complication. One device was replaced with a single-lead endocardial pacemaker at 1 year for increased thresholds. Leadless pacemaker device insertion is feasible in pediatric patients. Further studies and long-term follow-up are needed to ascertain device longevity and complication rates.

RESUMO

Children undergoing cardiac surgery often receive acetaminophen (paracetamol) as part of their postoperative pain treatment. To date, there is no information on the pharmacokinetics (PK) of acetaminophen in this special population, even though differences, as a result of altered hemodynamics and/or use of cardiopulmonary bypass, may be anticipated. Therefore, the aim of this study was to investigate the PK of intravenous acetaminophen in children after cardiac surgery with cardiopulmonary bypass. In the study, both children with and without Down syndrome were included. A population PK analysis, using NONMEM 7.2, was performed based on 161 concentrations of acetaminophen, acetaminophen sulfate, acetaminophen glucuronide, and oxidative metabolites from 17 children with Down syndrome and 13 children without Down syndrome of a previously published study (median age, 177 days [range, 92-944], body weight, 6.1 kg [4.0-12.9]). All children received 3 intravenous acetaminophen doses of 7.5 mg/kg (<10 kg) or 15 mg/kg (≥10 kg) at 8-hour intervals after cardiac surgery. For acetaminophen and its metabolites, 1-compartment models were identified. Clearance of acetaminophen and metabolites increased linearly with body weight. Acetaminophen clearance in a typical child of 6.1 kg is 0.96 L/h and volume of distribution 7.96 L. Down syndrome did not statistically significantly impact any of the PK parameters for acetaminophen, nor did any other remaining covariate. When comparing the PK parameters of acetaminophen in children after cardiac surgery with cardiopulmonary bypass with those from children of the same age following noncardiac surgery reported in the literature, clearance of acetaminophen was lower and volume of distribution higher.

RESUMO

Prenatal detection of structural congenital heart disease (CHD) optimises cardiovascular stability pre-operatively and post-operative outcomes. We compared prenatal detection rates of critical CHD in units offering universal fetal anomaly scans with those offering imaging to selected women. One hundred and thirteen infants met inclusion criteria. The overall pre-natal detection rate for critical CHD was 57% of liveborn infants. It was 71% (57/80) in hospitals who offered a universal anomaly scan and 29% (9/31) in centres offering a limited service. Postnatal diagnosis was associated with PICU admission (p=0.016) and preoperative mechanical ventilation (p=0.001). One-year mortality was 10 fold higher in the postnatally diagnosed group 15% vs 1.55% (p=0.0066). There is a significant disparity between centres offering universal anomaly versus selective screening. Prenatal detection confers advantage in terms of pre-operative stability and one year survival. Failure to deliver an equitable service exposes infants with CHD to avoidable risk.

RESUMO

Introduction There is little published research evaluating attitudes towards patient safety culture and working conditions in neonatal units. This study aimed to explore this within a Level III Irish neonatal unit setting. Methods This was a quantitative, cross-sectional study performed in the Rotunda Hospital, Dublin. A 30-item safety attitudes questionnaire (SAQ) was utilized to analyze staff perceptions in areas including job satisfaction, working conditions and stress recognition. Results The 'Stress Recognition' domain received the highest score (75.3) followed by 'Job Satisfaction' domain with a mean score of 74.4. The lowest mean scale score in the neonatal unit was for 'Perceptions of Management', with a mean score of 50.7. Collaboration and Communication scores were high across all disciplines. Conclusion This SAQ has highlighted a number of important areas for quality improvement and staff satisfaction in our neonatal unit.

RESUMO

BACKGROUND.: Non-invasive cardiac output monitoring (NICOM) using bioreactance (BRT) in pregnancy is gaining interest but lacks validation. We compared simultaneous cardiac output (CO) measurements obtained using the NICOM ® (BRT-CO) and echocardiography (echo-CO), and assessed the relationship between maternal characteristics and myocardial performance. METHODS.: Paired stroke volume (SV) and CO readings were obtained using NICOM ® and echocardiography, in a group of healthy nulliparous women throughout a 15 min period. Agreement between NICOM ® and echocardiography was assessed using Bland-Altman analysis and the intraclass correlation coefficient (ICC). Left ventricular (LV) function was assessed using systolic strain and tissue Doppler velocities (S', E', and A' waves). RESULTS.: Thirty-five women with a median [interquartile range] age, weight, and gestation of 29 [26-34] yr, 71 [64-79] kg, and 28 [21-29] weeks, respectively, were enrolled. There was good agreement between NICOM ® -measured and echocardiographically measured SV [mean bias 6 ml (limits of agreement -18 to 29); ICC 0.8 (95% confidence interval 0.6-0.9), P <0.001] and CO [mean bias 0.2 litres (limits of agreement -1.3-1.7); ICC 0.8 (95% confidence interval 0.7-0.9), P <0.001; mean percentage error ±26%; coefficient of error (precision)=3.4%]. The mean ( sd ) LV S' was 9.7 (2.3) cm s -1 . The mean ( sd ) LV strain was -18.6 (2.6)%. There was a negative relationship between BMI and LV diastolic function measured using the E':A' ratio ( r = -0.51, P <0.01). CONCLUSIONS.: Stroke volume and CO measurements obtained using NICOM ® were comparable to those obtained using echocardiography, with acceptable limits of agreement. Increased maternal BMI negatively impacts LV diastolic function measured using tissue Doppler imaging.

RESUMO

There is currently insufficient evidence to create a standardised protocol for the use and weaning of inhaled nitric oxide (iNO). We aimed to determine our application of iNO in this patient cohort. We performed a retrospective chart review on patients receiving iNO therapy for persistent pulmonary hypertension of the newborn (PPHN) from a single tertiary neonatal centre in 2014. The data was entered into the European Inhaled Nitric Oxide Registry. Thirty two babies were treated with iNO during this period, 9 of which were less than 32 weeks gestation. The median time to initiation of iNO treatment was 4-5 hours and the median duration of treatment was 74 hours for term and 66 hours for preterm infants. We recommend that further use of the European Inhaled Nitric Oxide Registry across more neonatal units in the Republic of Ireland could lead to the development of national guidelines on iNO use and weaning in this cohort.
