OBJECTIVE Stewart's strong ion theory quantifies unmeasured tissue acids produced following hypoxia or hypoperfusion, by calculation of the strong ion gap. Our study objectives were as follows: a) to determine the 24-hr profile of the strong ion gap following cardiopulmonary bypass surgery; and b) to compare the prognostic value in terms of intensive care(More)
Objective: Transoesophageal Doppler (TOD) has been used in adults to optimise left ventricular filling on the basis of the waveform parameters. We wished to see if a similar relationship exists in children, specifically: (a) whether change in thermodilution stroke volume (SV) following a fluid bolus corresponded to change in Doppler stroke distance, Doppler(More)
Plastic bronchitis, a condition associated with widespread mucous plugging of the tracheobronchial tree, is an increasingly recognised bronchoscopic finding in acute chest syndrome of sickle cell disease. Removal of casts by bronchoscopy is technically challenging. We describe a child with acute chest syndrome where bronchoscopic removal of extensive(More)
We aimed to document our experience with oral clonidine when used as a sedative in combination with intravenous morphine and lorazepam in a group of mechanically ventilated children with single-organ, respiratory failure. In particular, our objectives were to establish the relationship between oral dose, plasma concentration, and sedative effect, and(More)
A total of 8 infants presenting with sepsis-like illness were diagnosed to have human parechovirus (HPeV) infection; of which, 5 had abdominal distension and 6 had an erythematous rash. A combination of abdominal distension and erythematous rash was observed in 4 infants. The abdominal symptoms can be very prominent and signs could be confused with acute(More)
BACKGROUND Delayed sternal closure is commonly used following pediatric cardiopulmonary bypass surgery for many reasons including support of the failing myocardium. We hypothesized that, as a result of improvements in perioperative care, sternal closure could be achieved at an earlier postoperative time than the 3 to 5 days typically reported in the(More)
Objective: Stewart's physicochemical approach to acid-base balance defines the aetiology of a metabolic acidosis by quantifying anions of tissue acids (TA), which consist of unmeasured anions (UMA) and/or lactate. We hypothesised that an increase in TA during metabolic acidosis would lead to a compensatory fall in the plasma chloride (Cl) relative to sodium(More)
Dear Editor, The use of clinical information systems (CIS) and electronic prescribing have been shown in single centre studies to improve access to vital data, enhance patient safety and reduce manual documentation time in critical care [1, 2]. There are few large-scale reports of CIS utilisation in paediatric intensive care units (PICU). As part of the(More)
