Development of stratification criteria of green codes in a pediatric emergency department: a pilot study.

BACKGROUND: The aim of this study was to find stratification criteria in a group of children assigned to the green triage category at an emergency department (ED). METHODS: We analyzed a sample of patients admitted to the ED of Gaslini Children's Hospital in Genoa between February 2014 and January 2015 who had been given a green code on triage. We analyzed the following parameters: age, sex, nationality, reason for admission, number and type of the procedures performed, length of stay in the ED, destination on discharge, color code and diagnosis on discharge. RESULTS: Of the 2875 patients enrolled, 258 (8.97%) were hospitalized, 135 (4.70%) were placed in short intensive observation, 1609 (55.97%) were discharged from the ED without any intervention, 829 (28.83%) were discharged after undergoing procedures (blood tests, microbiology investigation, imaging, specialist evaluation) and 44 (1.5%) spontaneously left the ED. Among the patients who were hospitalized and those kept under short intensive observation, the most frequent discharge diagnosis was gastrointestinal disease; among those patients discharged with and without undergoing procedures, the most frequent diagnosis was respiratory disease. The mean age of patients admitted to hospital and of those discharged without undergoing procedures was 46 months, while the mean ages of patients kept under short intensive observation and of those discharged after undergoing procedures were 54 and 61 months, respectively. CONCLUSIONS: These preliminary results suggest that one of the main criteria of stratification of green codes on triage is the association between 2 variables: age and pathology.

Use of percutaneous radial artery catheter for peripheral blood progenitor cell collection in pediatric patients.

BACKGROUND: Leukapheresis procedures require adequate flow rates, which in children may frequently involve invasive vascular access placement. STUDY DESIGN AND METHODS: A minimally invasive peripheral radial artery catheter was used for drawing blood in 85 leukapheresis procedures performed in 33 pediatric patients. Blood return to the patients was provided by either a central Broviac-type catheter or a peripheral venous access. The patients' age range was 1 to 18 years (median, 9.5) and the weight range was 9 to 73 kg (median, 29 kg). Vasocan Braunüle Luer Lock IV cannulas (22 gauge in 78 and 20 gauge in 7) were placed percutaneously under local anesthesia, and in 8 patients, catheter placement was carried out during general anesthesia for other procedures. A continuous flow cell separator was used in all cases (Fresenius AS104 in 23 and AS204 in 62). RESULTS: Flow rates ranged from 18 to 45 mL per minute, the mean number of total blood volumes processed was 2.07 (range, 0.51-2.51), and the mean duration of the procedures was 150 minutes (range, 90-260). The 22-gauge cannulas provided adequate flow rates independently of patient age and weight. No significant thrombotic, embolic, hemorrhagic, ischemic, or infectious complications were observed. CONCLUSION: Peripheral radial artery catheters are safe, are minimally invasive, and provide steady, high-flow rates, and they should be considered for patients requiring leukapheresis and lacking a suitable vascular access for drawing blood.
