Filter by:Medication errors are common in children. Characteristics of errors during critical situations in the Emergency Department are ill-defined and might be more frequent than previously thought. However, optimal strategies to eliminate the risk of prescribing errors remain unknown. Many smartphone apps have been suggested over the last years with some of them designed to calculate medication dosage for children. The impact of these apps to decrease dosage error has never been evaluated in resuscitation setting. The aim of the study is to evaluate whether the use of a smartphone application designed to calculate medication doses decreases prescribing errors among residents during pediatric simulated resuscitations. This will be a crossover-randomized trial using high fidelity simulation among 40 residents rotating in the pediatric emergency department.
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Although there are several causes of fatal anaphylaxis, food allergy is one of the most common. Epinephrine is recommended as the initial treatment of choice for anaphylaxis. A delay in epinephrine administration may contribute to an increased risk of death. Therefore, the World Allergy Organization recommends that, for the treatment of anaphylaxis, epinephrine solution be administered intramuscularly in the mid-anterolateral thigh. In France 3 auto-injector pens are available: Anapen®, Epipen® and Jext®. For weight> 30 kg, the devices have a needle size respectively of 7.49 mm, 15.02 mm and 15.36 mm. For the weights between 15 and 30 kg needle size is 7.49 mm to 12.7 mm and Anapen® for Epipen® and Jext®. Several studies suggest that the needle length needle is sometim
Through several questionaries the investigators will measure the satisfaction of patients diagnosed with anaphylaxis in the use of a medical device for the adrenaline autoinjector, a smart case for an epinephrine autoinjector connected via Bluetooth to a mobile application.
In Italy, few data about anaphylaxis due to peanuts in pediatric age are available, conversely data about walnuts/hazelnuts, shellfish/mollusks anaphylaxis have not yet been collected. Children with physician-confirmed food allergy to peanuts, walnuts/hazelnuts and shellfish/mollusks will be recruited from 9 allergy clinics located in the Italian Territory (Bologna, Lecce, Napoli, Palermo, Parma, Pavia, Roma, Torino, Trento). Parent of food allergic children will compile a food allergy questionnaire (questions about general information on the family, on life and food habits, on indoor environment, on health status, on clinical aspects of the allergy, on the access to diagnostic and treatment resources). Parent of healthy children will compile a control questionnaire (questions about general information on the family, on life and food habits and on indoor environment) The 1-year survey will determine the frequency of anaphylaxis in allergic outpatient children.
Peanut allergy can be life-threatening. Current diagnostic techniques for peanut allergy have high sensitivity, but not high specificity. This clinical trial will test the validity of a novel blood biomarker (compared with current testing) as a diagnostic predictor of anaphylaxis to peanut.
The purpose of this study is to assess the potential for hypersensitivity symptoms upon repeat exposure to sugammadex. Healthy participants will be randomized to one of three treatment arms: sugammadex 4 mg/kg, sugammadex 16 mg/kg or placebo. Participants will receive 3 single intravenous (IV) doses of their randomized treatment, with an approximately 5-week washout between Dose 1 and Dose 2 and between Dose 2 and Dose 3. Participants will be confined at the study center from the day before each dose until completion of the 24-hour post dose assessments.
In about 10% of preoperative anaphylactic reactions to Neuro-Muscular Blocking Agents (NMBA) (114 patients analyzed at the BICHAT Hospital), a classical mechanism (mast cell- and IgE-dependent) is not identified. The mechanisms underlying these atypical anaphylactic reactions are unknown. The investigators have developed at the Pasteur Institute a murine model of anaphylaxis in which neutrophils, IgG and Platelet Activating Factor (PAF) play predominant roles. In addition, preliminary results obtained at the BICHAT Hospital suggest the presence of specific IgG anti-quaternary ammonium in the sera of patients that had developed a shock to NMBA anesthesia, but not in controls exposed to NMBA anesthesia or in normal blood donors. Finally, the release of neutrophil extracellular traps (NETs), extracellular filaments made of DNA and histones, may contribute to respiratory symptoms HYPOTHESIS: Neutrophils are implicated in NMBA -induced anaphylactic reactions in humans. Activated by IgG-NMBA complexes, which aggregate IgG receptors, neutrophils release PAF and NETs that are implicated in the cardiac and respiratory distress during anaphylaxis. It is possible that the activation of neutrophils: 1) explains the clinical features of atypical anaphylactic reactions (non-IgE mediated), 2) participates also in part to classical anaphylactic reactions GENERAL OBJECTIVE: Compare the percentage of circulating activated neutrophils in a group of patients immediately following a NMBA -induced shock (case) to that of a group of patients exposed to NMBA during anesthesia without developing a shock (control). SECONDARY OBJECTIVES: A) the day of the shock, quantify and compare between case and controls, 1) the level of circulating anti-quaternary ammonium IgG by immuno fluorometry, 2) the expression of IgG receptors (FcR) on the surface of neutrophils by cytometry, 3) the levels of circulating PAF by mass spectrometry, 4) the amount of NETs by immunofluorescence. B) 6 to 10 weeks after the shock perform, 1) cutaneous tests to NMBA, 2) a study of the capacity of stimulation of ex vivo neutrophils by IgG- NMBA complexes
The purpose of this study was to investigate the utility of serum tryptase for the confirmation of shrimp-induced anaphylaxis.
This study is a preliminary report of pharmacokinetic data of epinephrine administered via intranasal route (IN) comparing with intramuscular (IM) route in healthy adult volunteers.
The purpose of this study is to study the number of Participants with Adverse Events as a Measure of Safety and Tolerability.
