Randomized Controlled TrialEffect of preoperative education on behaviour of children during induction of anaesthesia: a randomised clinical trial of efficacy.
In this randomised prospective study we aimed to evaluate whether preoperative anaesthetic education delivered to children on the day of surgery reduces anxiety behaviour during induction of anaesthesia. One hundred children, six to 15 years of age, undergoing general anaesthesia for ambulatory surgery were allocated at random to a preoperative education group (n=50) or a control group (n=50). The main outcomes were behaviour score, self-reporting of satisfaction score and identification of the stage when children felt most fearful. ⋯ Intravenous induction failed in nine out of 38 children in the intervention group (23.7%) compared to five out of 40 in the control group (12.5%). When intravenous induction failed, eight out of nine (89%) of the intervention group remained co-operative during gas induction compared to two out of five (40%) of the control group. Preoperative education delivered on the day of surgery did not reduce anxiety behaviour in children during intravenous induction of anaesthesia, but did reduce anxiety during subsequent inhalational induction.

Blood culture collection in patients with acute kidney injury receiving renal replacement therapy: an observational study.
Critically ill patients receiving renal replacement therapy (RRT) for acute kidney injury (AKI) have high reported intensive care unit (ICU) mortality. Blood culture (BC) collection practices in this population have to date been poorly characterised, specifically in regards to the influence of RRT on the clinical triggers for such an investigation. Utilising our electronic clinical information system, we conducted a retrospective observational study of patients admitted to a 30-bed tertiary level ICU and requiring RRT over a four-year period. ⋯ We also observed a predominance of candidaemia in this cohort, despite the absence of neutropenia. This study provides unique data describing BC collection rates in a cohort of critically ill patients receiving RRT for AKI and at high risk of dying. Further study of temperature alteration, detection of bloodstream infection and outcome in patients receiving RRT is now warranted.
