How in situ simulation affects paediatric nurses' clinical confidence.

Considering the emphasis on safety in health care, new methods for training qualified nurses are being considered. The use of simulation technologies to provide regular and repeated training for qualified nurses in the management of paediatric emergencies has yet to be investigated. This paper presents the results of a study designed to determine if and how a period of regular simulation training in the management of paediatric emergencies improves qualified nurses' clinical confidence. A mixed methods design was employed using a group of qualified paediatric nurses (n=20) who were matched into two groups. The intervention group (n=10) received three simulation-based training sessions and the control group (n=10) had no training. Each nurse completed a pre- and post-clinical confidence questionnaire and were interviewed. Results demonstrated a statistically significant improvement in confidence following simulation training, which was explained by the provision of insight and preparation for real life. Further research should aim to replicate these findings using larger sample sizes and direct assessments of nurses' clinical performance.

Bacterial tracheitis: a multi-centre perspective.

The published literature on bacterial tracheitis is limited. We report the first multi-centre study of bacterial tracheitis together with a concise review of the literature. We conducted a retrospective study of cases admitted during the period 1993-2007 to 3 tertiary paediatric centres in the United Kingdom and 1 in Australia. A total of 34 cases were identified. 31 patients (91%) required intubation. Complications included cardiorespiratory arrest in 1, ARDS in 1, hypotension in 10, toxic shock syndrome in 1 and renal failure in 1 patient(s). Staphylococcus aureus was the most commonly implicated bacterial organism, isolated from the respiratory tract in 55.8% of the cases overall. Other pathogens commonly isolated from the respiratory tract included Streptococcus pyogenes (5.9%), Streptococcus pneumoniae (11.8%) and Haemophilus influenzae (11.8%). Viral coinfection was identified in 9 (31%) of the 29 cases in whom immunofluorescence testing was performed (influenza A in 4 cases; parainfluenza 1 in 2 cases; parainfluenza 3 in 2 cases; adenovirus in 1 case). The combined experience from 4 major paediatric intensive care units suggests that bacterial tracheitis remains a rare condition with an estimated incidence of approximately 0.1/100,000 children per year. Short-term complications were common but long-term sequelae were rare. There were no fatal outcomes, which contrasts with the high historical mortality rates and likely reflects improvements in intensive care management.

Negative pressure ventilation in pediatric critical care setting.

Invasive ventilation is associated with both pulmonary and non-pulmonary complications. There has been a renewed interest in the use of negative pressure ventilation (NPV) for various medical conditions to minimise the complications associated with positive pressure ventilation. The routine use of NPV in an ICU setting still requires further studies and research. In this article, the authors review the clinical applications of NPV together with associated risks and limitations. Case reports of patients with cardiac, neuromuscular and respiratory diseases managed with NPV on our unit are described. NPV improved the clinical condition in each of these patients and decreased the requirement for invasive therapy.

Children with human immunodeficiency virus admitted to a paediatric intensive care unit in the United Kingdom over a 10-year period.

OBJECTIVE: There is little published experience regarding the outcome of children with human immunodeficiency virus (HIV) infection treated on a paediatric intensive care unit (PICU). We describe the outcome of children with HIV infection in our hospital over a 10-year period. METHOD: We performed a retrospective analysis of all children with HIV infection admitted to our PICU between August 1992 and July 2002. Their ages ranged from 2 months to 11 years (median 4 months). Information collected included demographic data, clinical presentation, investigations, treatment and outcome. RESULTS: There were 42 children with HIV infection admitted to PICU during the study period, with 66 admission episodes. Sixteen (38%) children died in PICU, and 26 (62%) survived their last PICU admission. Of these, 5 died at a later date (between 1 and 32 months after discharge from PICU) and 21 survived to the time of reporting. The most frequent reason for PICU admission was respiratory failure, due either to Pneumocystis carinii pneumonia (45% of admissions) or to other respiratory pathogens (32%). Over 80% of current survivors had good outcomes in terms of growth and development; 6 children had evidence of spastic diplegia. CONCLUSIONS: Although there is significant mortality among children with HIV infection admitted to PICU, many of them survive their admission, and over 80% of the survivors have good outcomes with the currently available highly active anti-retroviral therapy. This provides evidence that intensive care treatment is appropriate for this group of patients in the United Kingdom.
