Coming full circle: thirty years of paediatric fluid resuscitation.
Fluid bolus therapy (FBT) is a cornerstone of the management of the septic child, but clinical research in this field is challenging to perform, and hard to interpret. The evidence base for independent benefit from liberal FBT in the developed world is limited, and the Fluid Expansion as Supportive Therapy (FEAST) trial has led to conservative changes in the World Health Organization-recommended approach to FBT in resource-poor settings. ⋯ Such trials could examine differing strategies of fluid resuscitation, or compare early FBT to early vasoactive agent use. Given the ubiquity of FBT and the potential for harm, appropriately powered examinations of the efficacy of FBT compared to alternative interventions in the paediatric emergency and ICU settings in the developed world appear justified and warranted.

The effect of Rapid Response System revision on standard and specific intensive care unit outcomes in a regional hospital.
Hospital systems for the recognition (afferent limb) and management (efferent limb) of deteriorating patients, or Rapid Response Systems (RRSs), are being mandated worldwide, in spite of conflicting evidence regarding their efficacy. We have evaluated the impact of an Adult Deterioration Detection System (Q-ADDS)-based RRS specifically on illness severity at intensive care unit (ICU) admission and ICU length of stay (LOS), as well as previously studied endpoints. We undertook a retrospective, single-centre observational study comparing equivalent 18-month periods before the Q-ADDS-based RRS, and after implementation. ⋯ This Q-ADDS form-based RRS has resulted in lower illness severity at ICU admission from the ward, and fewer patients with scores associated with a >50% predicted mortality. Overall, ICU length of stay was reduced. These specific outcomes may reliably reflect RRS efficacy, even in smaller centres.

Severe hyperkalaemia complicating parathyroidectomy in patients with end-stage renal disease.
We evaluated the incidence of perioperative hyperkalaemia in end-stage renal disease (ESRD) patients undergoing parathyroidectomy and investigated possible contributors to this phenomenon. This was a retrospective cohort study looking at patients who had undergone parathyroidectomy for chronic kidney disease-associated mineral bone disease (CKD-MBD) at The Alfred Hospital, Melbourne, since 2001. Baseline demographics including age, gender, aetiology of renal failure and mode of renal replacement therapy as well as anaesthetic technique and duration of surgery were studied as possible contributors. ⋯ Potentially life-threatening hyperkalaemia poses a significant risk in the perioperative period. Serial electrolyte monitoring is crucial to safety in this patient group. A multidisciplinary approach to perioperative management is required to ensure optimal timing of renal replacement therapy and appropriate means of serial blood sampling.

Efficacy and safety of ultra rapid iron polymaltose infusion during general anaesthesia.
To assess the efficacy and safety of ultra rapid (15 minute) infusion of iron polymaltose to iron deficient patients during general anaesthesia, we performed a prospective, interventional non-randomised study on 99 adult patients with iron deficiency with or without anaemia presenting for surgery under general anaesthesia. Over 15 minutes during the maintenance phase of anaesthesia, patients were given iron polymaltose, 500 mg if not anaemic, or 1,000 mg if anaemic. Haemodynamic stability, immediate or delayed iron-related side-effects and efficacy at six weeks were assessed. ⋯ The incidence of immediate or delayed side-effects was similar to patients undergoing outpatient iron polymaltose infusions and reflective of a post-surgical population. We conclude that up to 1,000 mg of iron polymaltose can be given over 15 minutes without significant haemodynamic compromise to selected patients undergoing general anaesthesia. Iron polymaltose administered in this way appears efficacious in treating iron deficiency.
