Continuous flow peritoneal dialysis (CFPD) improves ultrafiltration in children with acute kidney injury on conventional PD using a 4.25 % dextrose solution.

BACKGROUND: Criticism against the use of acute peritoneal dialysis (PD) has been its low clearance and low ultrafiltration (UF) volumes compared to extracorporeal techniques. The aim of our study was to determine whether continuous flow peritoneal dialysis (CFPD) would improve UF in children with acute kidney injury (AKI) in cases where UF on conventional PD was inadequate using 4.25 % glucose concentrations. METHODS: Five infants were prospectively studied. All had AKI with fluid overload. The median age of the patients was 6 (range 0.43-9) months; the median weight was 6.5 (range 2.7-8.4) kg. Each patient served as his or her own control, undergoing both CFPD and conventional PD. CFPD was performed with two bedside-placed catheters using a 2.5 % glucose concentration. After initial filling, a dialysate flow rate of 100 ml/min/1.73 m(2) was maintained with an adapted continuous venovenous haemofiltration machine. The UF flow rate was set at 2.5 ml/min/1.73 m(2) and adapted as necessary. UF and clearance rates were measured for both PD and CFPD. RESULTS: The median UF rate achieved was 1.7 (range 0.01-5.30) mg/kg/h with conventional PD versus 6.7 (range 2.17-15.7) mg/kg/h with CFPD (p = 0.042). The clearances of urea and creatinine were 6.89 (range 4.50-7.55) and 7.46 (range 4.79-10.50) mL/min/1.73 m(2), respectively, with conventional PD and 19 (17.0-30.0) and 41 (standard deviation17.4, range 12.0-52.0) mL/min/1.73 m(2), respectively, with CFPD (both p = 0.043). CONCLUSION: Continuous flow peritoneal dialysis improves UF in fluid overloaded infants who are not achieving adequate UF on conventional PD.

Patient safety in South Africa: PICU adverse event registration*.

OBJECTIVE: Adverse event registration is a means to improve patient safety in a PICU. So far it has been used in European and North American countries mainly. We studied adverse events in a South African setting with the aims to 1) assess rates and types of adverse events with two different registration methods and 2) describe characteristics of patients experiencing adverse events. DESIGN: This study consisted of 1) a retrospective audit of randomly selected patient records and 2) a prospective observational study of real-time registration of AEs during ward rounds. Adverse events were identified using the Child Health Corporation of America - Pediatric Pharmacy Advocacy Group PICU trigger tool. SETTING: A multidisciplinary 20 bed PICU at the Red Cross War Memorial Children's Hospital in Cape Town. PATIENTS: The retrospective section of the study involved 80 randomly selected patients who had been discharged from the PICU, and the prospective study involved patients who were present in the PICU between March and June 2012. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The retrospective audit identified 260 adverse events in 61 patients (50.8 per 100 patient days). Nineteen patients (24%) did not have any adverse events. Catheter complications, hypoglycemia, and endotracheal tube malpositioning requiring repositioning were most frequent. Prospective registration during 58 ward rounds revealed 272 adverse events in 236 patients (27.2 per 100 patient days), particularly catheter complications, nosocomial infection, and surgical complications. Hundred thirty-two patients of the total 236 patients (56%) did not experience an adverse event. Patients experiencing adverse events underwent mechanical ventilation significantly more frequently. Length of stay was significantly associated with number of adverse events. CONCLUSIONS: The trigger tool method identifies a higher adverse event rate compared with real-time registration. Each method has a unique contribution to yield types of adverse events.

Ventilator associated pneumonia in major paediatric burns.

More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns.
