The use of childhood injury surveillance within a general accident and emergency department.

The prevention of accidental injury is a government priority in the United Kingdom. Following the recent Government White Paper, towards a Healthier Scotland (Scottish Office 1999), the issue of poverty and inequalities in health has come to prominence. This study, at Glasgow Royal Infirmary, looked at the socio-economic context of injuries and aimed to identify if there was a relationship between the frequency of injuries and the deprivation status of the patient. This paper examines one method of data collection, the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) which is currently being used at the local children's hospital. The practical difficulties of collecting this data within a busy, general Accident and Emergency (A&E) department are examined. The questionnaire uses narrative and sequence text to provide descriptive information relating to the injury and the events leading up to it. Findings demonstrated that a large percentage of children's injuries were treated at the child's local general hospital. Differences between the two hospitals were also found relating to the children's ages and where the injuries took place. Results also showed that the socio-economic distribution of childhood accidents is still a major problem in this city. Therefore, this study recommends that injury data should be collected at all A&E departments to establish an accurate picture of the pattern of injuries within the city.

How to modify a volume-cycled home ventilator to satisfy a child's need for pressure-limiting and continuous positive airway pressure during spontaneous breathing.

Piston driven volume-cycled home ventilators increase work of breathing in the synchronized intermittent mandatory ventilation mode. A 2-year-old trisomy 21 patient with chronic lung disease due to recurrent aspiration pneumonia required a ventilator rate of 6-8 breaths per minute awake and 15 asleep, with peak pressure of 32 cm H2O and positive end-expiratory pressure (PEEP) of 10 cm H2O. Two circuits were designed to facilitate breathing and respiratory mechanics of his spontaneous breaths on both were compared. A spring valve on the inspiratory line pressure-limited ventilation and at the end of the expiratory line provided PEEP in both systems. The reservoir system had a 2-liter bag on the inspiratory limb of the circuit, and two one-way valves at the patient connector to direct inspiratory and expiratory flow. The continuous positive airway pressure (CPAP) system provided continuous flow with a CPAP device set to deliver a pressure 2 cmH2O higher than the PEEP valve. On the CPAP system, compared to the reservoir system, dynamic compliance was greater [1.52 (0.14 SD) ml/cm H2O/kg vs. 0.39 (0.02), p < 0.001] and resistance less [8.15 (1.26) cm H2O/l/s vs. 45.86 (0.87), p < 0.001] as measured with a PeDS machine. This is an innovative use of a CPAP device.
