    Characteristics and outcome of long-stay patients in a paediatric intensive care unit in Cape Town, South Africa
    (2015) Nupen, Tracey Lee; Morrow, B M; Argent, A C
    Objectives: To describe a rational basis for the definition of a long-stay patient (LSP) in a South African paediatric intensive care unit (PICU); to review the characteristics and outcomes of the patients who comply with the LSP definition; to assess the proportion of resources allocated to the LSP cohort; and to determine if the results of this study could be used as a predictive tool for future admissions. Methods: A retrospective descriptive study of routine data collected over one calendar year (2009) from a 20-bedded multidisciplinary PICU was conducted. The definition of a LSP in this setting was established using various models. The characteristics and outcomes of the long- and short- stay groups were compared using nonparametric Mann-Whitney U and Chi2 tests, with significant results entered into a stepwise multiple regression model. The proportion of ICU days consumed by LSP was calculated. Human Research Ethics Committee approval was obtained (Ref/Rec 105/2011).

    Paediatric nonbronchoscopic bronchoalveolar lavage: Overview and recommendations for clinical practice
    (AOSIS, 2006) Morrow, B M; Futter, M J; Argent, A C
    NB-BAL is an effective procedure for the diagnosis of pulmonary disease processes in ventilated infants and children. This procedure is, however, not without risks to both patients and staff. Numerous complications of NB-BAL exist, with hypoxia being the most common. As a result, care should be taken in performing NB-BAL on haemodynamically unstable patients; patients with coagulation defects; and patients with cardiac or brain abnormalities. This paper presents an overview of paediatric nonbronchoscopic bronchoalveolar lavage (NB-BAL) including: the rationale for NB-BAL; the complications associated with the procedure; indications and contraindications. It also recommends an evidence-based clinical guideline for performing the procedure in the paediatric intensive care unit. By following the NB-BAL guidelines presented in this paper, one can ensure that an effective specimen is obtained from the lower respiratory tract, whilst minimising the risk to the patient.
