RESUMEN
BACKGROUND: Ultrasound guided peripheral intravenous catheter placement (USGPIV) has demonstrated benefits in children including higher success rates and fewer attempts compared to the traditional technique. Little is known about the experience needed to establish competence with USGPIV in children. In adult patients, nurses with four USGPIV attempts had a subsequent 70% probability of success after training. The objective of this study is to measure the competency of nurses with USGPIV in children after training. METHODS: Pediatric nurses completed 2 h of training on USGPIV, after which they used ultrasound at their discretion for children with difficult access. Data was collected prospectively via study forms and retrospectively from medical records. Mixed effects logistic regression models were used to estimate the probability of successful USGPIV placement. RESULTS: Thirty-five nurses underwent training from the pediatric emergency department and intravenous access team. The overall USGPIV success rate was 70%. Participants with less nursing experience made more USGPIV attempts than those with more experience, but had similar success rates. Forty percent of participants performed ten or more attempts during the study period. Mixed effects logistic regression estimated that it took nine USGPIV attempts after training for learners to achieve a 70% probability of success for the subsequent attempt. CONCLUSION: After training, 40% of participants adopted USGPIV into their practice. When developing training programs for USGPIV for children with difficult access, trainers can anticipate the experience needed to acquire this skill and the fact that not everyone trained will use this skill in their daily practice.

BACKGROUND AND OBJECTIVE: Patients with limited English proficiency (LEP) experience worse health care outcomes compared to English proficient (EP) patients, and professional interpretation is underutilized in clinical settings. The objectives of this study were to describe patterns of interpreter use in a pediatric emergency department (ED), to determine factors associated with its use, and to examine differences in outcomes between EP families and those with LEP. METHODS: ED encounters for LEP and EP patients were reviewed in a retrospective cohort study design over a 15 month period. Generalized estimating equations were used to compare patient encounters and factors associated with interpreter use. RESULTS: Interpreter use for families who preferred a non-English language was 45.4%. Use of interpretation was less likely during busier times of day (odds ratio [OR] 0.85, confidence interval [CI] 0.78-0.93), with a lower triage acuity (OR 0.66, CI 0.62-0.70), and with each increasing year of patient age (OR 0.97, CI 0.96-0.98). LEP patients who did not receive interpretation were less likely to be admitted than EP patients (OR 0.69, 0.62-0.78). Patients of LEP families, with or without interpretation, were more likely to be transferred to the ICU within 24 hours of admission than patients of EP families (OR 1.76, 1.07-2.90; 1.85, 1.08-3.18) suggesting that an aspect of clinical severity may have been missed in the ED. CONCLUSIONS: Professional interpretation is currently underutilized in this ED for patients with LEP, and important differences in outcomes exist between LEP and EP patients. Factors associated with interpreter use will inform ongoing improvement efforts.

Neuropeptide FF (NPFF) modulates opiate actions. It has pro-nociceptive effects, primarily through the NPFF receptor 1 subtype, and anti-nociceptive effects, primarily through the NPFFR2 subtype. AC-263093 is a small l, organic, systemically active molecule that was previously shown to functionally activate NPFFR2, but not NPFFR1. It was hypothesized that AC-263093 would attenuate morphine tolerance. Rats were tested for radiant heat tail-flick latency before and after 5 mg/kg morphine sulfate s.c. They were then rendered morphine-tolerant by continuous subcutaneous infusion of 17.52 mg/kg/day morphine sulfate. On the seventh day of infusion, they were retested for analgesia 10 and 20 min after 5mg/kg morphine sulfate s.c. Tolerance was indicated by reduction of morphine analgesia from the pre-infusion test. Fifty minutes prior to morphine challenge, rats received either 10 mg/kg i.p. AC-263093 or injection vehicle alone. AC-2623093-treated rats had far smaller tolerance scores than control rats. This drug effect was significant, p = 0.015. The same dose of AC-263093 had almost no analgesic effect in non-tolerant, saline-infused rats. In vitro experiments revealed that AC-263093 had equal affinity for NPFFR1 and NPFFR2, and functionally inactivated NPFFR1, in addition to its previously shown ability to activate NPFFR2. Thus, altering the balance between activation of NPFF receptor subtypes may provide one approach to reversing opiate tolerance.
