ABSTRACT

BACKGROUND: Aminophylline, an established bronchodilator, is also purported to be an effective diuretic and anti-inflammatory agent. However, the data to support these contentions are scant. We conducted a prospective, open-label, single arm, single center study to assess the hypothesis that aminophylline increases urine output and decreases inflammation in critically ill children. METHODS: Children less than 18 years of age admitted to the pediatric intensive care unit who were prescribed aminophylline over a 24-h period were eligible for study. The use and dosing of aminophylline was independent of the study and was at the discretion of the clinical team. Data analyzed consisted of demographics, diagnoses, medications, and markers of pulmonary function, renal function, and inflammation. Data were collected at baseline and at 24-h after aminophylline initiation with primary outcomes of change in urine output and inflammatory cytokine concentrations. RESULTS: Thirty-five patients were studied. Urine output increased significantly with aminophylline use [median increase 0.5 mL/kg/h (IQR: -0.3, 1.3), p = 0.05] while blood urea nitrogen and creatinine concentrations remained unchanged. Among patients with elevated C-reactive protein concentrations, levels of both interleukin-6 (IL-6) and IL-10 decreased at 24 h of aminophylline therapy. There were no significant differences in pulmonary compliance or resistance among patients invasively ventilated at both time points. Side effects of aminophylline were detected in 7 of 35 patients. CONCLUSION: Although no definitive conclusions can be drawn from this study, aminophylline may be a useful diuretic and effective anti-inflammatory medication in critically ill children. Given the incidence of side effects, the small sample size and the uncontrolled study design, further study is needed to inform the appropriate use of aminophylline in these children.

ABSTRACT

The treatment of pulmonary arterial hypertension (PAH) associated with chronic lung disease of infancy (CLDI) is becoming commonplace. However, an optimal approach to the monitoring of this treatment has not been clearly established, and data suggest that such therapy may not be without risk. This study assessed the feasibility and safety of pulmonary artery catheter (PAC) placement and its role in the management of PAH associated with CLDI. The medical records of 12 infants with CLDI requiring chronic mechanical ventilation who underwent PAC monitoring were reviewed. Data analyzed included demographics, hemodynamic data, PAH pharmacological therapy, respiratory support, echocardiographic data, sedation level, complications related to PAC use, and mortality. In this analysis, PAC placement and monitoring was found to be feasible, appeared safe, and was associated with the ability to wean inspired oxygen, decrease sedation, and titrate PAH therapy without untoward effect. However, no definitive conclusions can be drawn from this report given its small sample size and uncontrolled, retrospective design. It is hoped that these data will renew interest in PAC monitoring for CLDI and foster prospective study where its true value can be ascertained.

ABSTRACT

BACKGROUND: Transoesophageal echocardiography has become a powerful tool in the diagnosis and management of children with congenital cardiac malformations. Unlike adults, children will not tolerate transoesophageal echocardiography under light sedation. This study was undertaken, therefore, to evaluate the safety and efficacy of deep sedation with propofol for transoesophageal echocardiography in children examined in an outpatient setting. METHODS: This is a retrospective study of patients undergoing transoesophageal echocardiography with propofol given in bolus aliquots to achieve a level of sedation adequate to insert the transoesophageal echocardiographic probe and maintain sedation throughout the procedure. RESULTS: We included a total of 118 patients, 57% being male, with a mean age of 12.9 years. Adequate sedation was achieved using a mean propofol dose of 8.3 milligrams per kilogram, with the dose per kilogram decreasing concomitant with increasing weight of the patient. Patients less than two years of age were intubated for the procedure. There were no clinically significant changes in cardiac function or haemodynamics. Non-intubated patients received supplemental oxygen prior to, or just after, the onset of sedation, with transient hypoxaemia observed in one-fifth. Complications were rare, with minor problems occurring in 7.6%, and major ones in 4%. CONCLUSIONS: Transoesophageal echocardiography can be performed on an outpatient basis in children with a wide spectrum of congenital cardiac malformations, and propofol is an ideal sedative agent in this setting. Although not common, preparations must be made for significant haemodynamic and respiratory complications. In our study, we intubated all the children under 2 years of age.

ABSTRACT

Pulmonary hypertension (PH) can be associated with bronchopulmonary dysplasia (BPD) of infancy, and mortality in these pediatric patients is high without aggressive medical treatment. Continuous intravenous epoprostenol (prostacyclin) was shown to lower pulmonary artery pressures (PAP) in children with idiopathic pulmonary arterial hypertension (PAH), formerly referred to as primary pulmonary hypertension. We report on the first case of long-term home ventilation in combination with chronic intravenous epoprostenol in a child with severe pulmonary hypertension associated with chronic lung disease. This aggressive combination resulted in significant improvement in pulmonary artery pressures, substantial improvement in quality of life, and eventual discontinuation of home ventilation.
