    The purpose of these practice guidelines is to offer and share strategies for preventing extravasation and measures for handling drugs known to cause tissue necrosis, which may occur even with the most skilled experts at intravenous (IV) injection. Herein, general knowledge about extravasation is first described, including its definition, incidence, risk factors, diagnosis, differential diagnosis, and extravasation injuries. Management of extravasation includes nursing intervention and thermal application. At the first sign of extravasation, nursing intervention with following steps is recommended: stop administration of IV fluids immediately, disconnect the IV tube from the cannula, aspirate any remaining drug from the cannula, administer drug-specific antidote, and notify the physician. Local thermal treatments are used to decrease the site reaction and absorption of the infiltrate. Local cooling (ice packs) aids in vasoconstriction, theoretically limiting the drug dispersion. Although clear benefit has not been demonstrated with thermal applications, it remains a standard supportive care. The recommended application schedule for both warm and cold applications is 15 to 20 minutes, every 4 hours, for 24 to 48 hours. For prevention of extravasation, health professionals should be familiar with the extravasation management standard guidelines. They should regularly check the extravasation kit, assess patients’ sensory changes, tingling or burning, and always pay attention to patients’ words. The medical team’s continuous education on extravasation is essential. With the practical use of these guidelines, it is expected to reduce the occurrence rate of extravasation and contribute to patient care improvement.

    Intravenous (IV) contrast material is used extensively for CT and MRI scans done in emergency departments (ED). Its use is essential to make many critical diagnoses in ED patients. While adverse reactions can occur, newer research has added to our knowledge of IV contrast media tolerance and safety leading to improved and more liberal guidelines for intravenous contrast use. The updated information described in this review article indicates how intravenous contrast can be used safely in more patients, more expeditiously and with fewer precautions than with prior guidelines. This review article explains the basis for the new recommendations for intravenous contrast material use and describes indicated precautions and preparations to avoid adverse reactions for iodinated agents used for CT and gadolinium agents for MRI.

    OBJECTIVE: To develop technical guidelines for computed tomography urography.
    METHODS: The French Society of Genitourinary Imaging organised a Delphi consensus conference with a two-round Delphi survey followed by a face-to-face meeting. Consensus was strictly defined using a priori criteria.
    RESULTS: Forty-two expert uro-radiologists completed both survey rounds with no attrition between the rounds. Ninety-six (70%) of the initial 138 statements of the questionnaire achieved final consensus. An intravenous injection of 20 mg of furosemide before iodinated contrast medium injection was judged mandatory. Improving the quality of excretory phase imaging through oral or intravenous hydration of the patient or through the use of an abdominal compression device was not deemed necessary. The patient should be imaged in the supine position and placed in the prone position only at the radiologist\'s request. The choice between single-bolus and split-bolus protocols depends on the context, but split-bolus protocols should be favoured whenever possible to decrease patient irradiation. Repeated single-slice test acquisitions should not be performed to decide of the timing of excretory phase imaging; instead, excretory phase imaging should be performed 7 min after the injection of the contrast medium. The optimal combination of unenhanced, corticomedullary phase and nephrographic phase imaging depends on the context; suggestions of protocols are provided for eight different clinical situations.
    CONCLUSIONS: This expert-based consensus conference provides recommendations to standardise the imaging protocol for computed tomography urography.
    CONCLUSIONS: • To improve excretory phase imaging, an intravenous injection of furosemide should be performed before the injection of iodinated contrast medium. • Systematic oral or intravenous hydration is not necessary to improve excretory phase imaging. • The choice between single-bolus and split-bolus protocols depends on the context, but split-bolus protocols should be favoured whenever possible to decrease patient irradiation.

    Acute adrenal insufficiency (AAI) is a potentially fatal medical emergency whose prevention and treatment should be known by all medical professionals. AAI is an underdiagnosed condition because of its non-specific symptoms, but its diagnosis and early treatment with glucocorticoids is vital. It may be triggered by a de novo deficiency in cortisol synthesis or occur secondarily to omission of hormone replacement therapy (corticosteroids) or inadequate adjustment of the dose required in stress situations in patients previously diagnosed with adrenal insufficiency. AAI prevention significantly decreases death from cardiovascular diseases and infections in patients with adrenal insufficiency, and also improves their quality of life. Adequate education of patients, relatives, and all healthcare professionals is therefore essential. Therefore, the Adrenal Disorders Group of the Neuroendocrinology Area of the Spanish Society of Endocrinology and Nutrition (SEEN) has prepared, at the proposal of the SEEN\'s board, a guideline for optimal management of acute adrenal insufficiency. The guideline is intended to provide practical recommendations for all healthcare professionals who may be involved in the diagnosis, treatment, and prevention of AAI. It is also intended to provide patients and their families with action guidelines for AAI management and prevention.

    The opioid crisis is a growing concern for Americans, and it has become the leading cause of injury-related death in the United States. An adjunct to respiratory support that can reduce this high mortality rate is the administration of naloxone by Emergency Medical Services (EMS) practitioners for patients with suspected opioid overdose. However, clear evidence-based guidelines to direct EMS use of naloxone for opioid overdose have not been developed. Leveraging the recent Agency for Healthcare Research and Quality (AHRQ) systematic review on the EMS administration of naloxone for opioid poisonings, federal partners determined the need for a clinical practice guideline for EMS practitioners faced with suspected opioid poisoning. Project funding was provided by the National Highway Traffic Safety Administration, Office of EMS, (NHTSA OEMS), and the Health Resources and Services Administration, Maternal and Child Health Bureau\'s EMS for Children Program (EMSC). The objectives of this project were to develop and disseminate an evidence-based guideline and model protocol for administration of naloxone by EMS practitioners to persons with suspected opioid overdose. We have four recommendations relating to route of administration, all conditional, and all supported by low or very low certainty of evidence. We recommend the intravenous route of administration to facilitate titration of dose, and disfavor the intramuscular route due to difficulty with titration, slower time to clinical effect, and potential exposure to needles. We equally recommend the intranasal and intravenous routes of administration, while noting there are variables which will determine which route is best for each patient. Where we are unable to make recommendations due to evidence limitations (dosing, titration, timing, and transport) we offer technical remarks. Limitations of our work include the introduction of novel synthetic opioids after many of the reviewed papers were produced, which may affect the dose of naloxone required for effect, high risk of bias and imprecision in the reviewed papers, and the introduction of new naloxone administration devices since many of the reviewed papers were published. Future research should be conducted to evaluate new devices and address the introduction of synthetic opioids.

    BACKGROUND: Systemic sclerosis (SSc) is an autoimmune chronic disease characterized by vascular impairment, immune dysfunction and collagen deposition. Raynaud\'s phenomenon (RP) and digital ulcers (DU) are prominent features of SSc. Intravenous (IV) iloprost (ILO), according to the recently updated EULAR recommendations, is indicated for RP after failure of oral therapy. Moreover, IV ILO could be useful in DU healing. IV ILO is currently available mainly on the European market approved for RP secondary to SSc with 3-5 days infusion cycle. Unfortunately, data published varies regarding regimen (dosage, duration and frequency). Up to now, ILO has been studied in small cohorts of patients and in few randomized controlled trials.
    METHODS: A systematic review of studies on IV ILO in patients with SSc complicated by DU and RP was performed. Insufficient data were available to perform a meta-analysis according to the GRADE system. We performed a three-stage internet-based Delphi consensus exercise.
    RESULTS: Three major indications were identified for IV ILO usage in SSc: RP non-responsive to oral therapy, DU healing, and DU prevention. IV ILO should be administered between 0.5 and 2.0ng/kg/min according to patient tolerability with a frequency depending on the indication.
    CONCLUSIONS: Although these suggestions are supported by this expert group to be used in clinical setting, it will be necessary to formally validate the present suggestions in future clinical trials.

    静脉注射对乙酰氨基酚(对乙酰氨基酚)未获许可用于早产儿或<2岁的婴儿的镇痛。分别,在欧洲和美国。因此,在标签外使用多种给药方案。因为证据支持使用相同的目标平均稳态扑热息痛浓度(Cssmean,9-11mg/L)用于缓解新生儿的疼痛,与年龄较大的儿童和成人相比,以两步法评估基于该Cssmean的给药方案。
    首先,我们进行了系统搜索,以提供基于药代动力学(PK)的新生儿疼痛给药指南(随后在这些论文中进行了安全性搜索).第二,根据这些给药指南生成浓度-时间曲线,为对乙酰氨基酚治疗新生儿疼痛提供给药建议.
    在2334篇潜在相关文章中,包括9项研究。对于典型的足月新生儿,包装(标签)中指定的剂量导致Cssmean低于目标(7.65mg/L),虽然研究者发起的研究的剂量导致Cssmean高于(15.31),或附近的目标(11.78和10.21)对于(前)足月新生儿>32周。只有一项研究表明,在<32周的早产儿中,剂量会导致定制的浓度(8.7)。
    负荷剂量为20mg/kg,其次是10mg/kg/6h建议32-44周的新生儿,这是由短期安全支持。对于<32周的新生儿,12mg/kg的负荷剂量和6mg/kg/6h的维持剂量似乎导致目标Cssmean,尽管需要更多的临床研究来支持其安全性。
    Intravenous paracetamol (acetaminophen) has not been licensed for analgesia in preterm neonates or infants < 2 years, respectively, in Europe and the United States. A variety of dosing regimens is therefore used off-label. Because evidence supports the use of the same target mean steady state paracetamol concentration (Cssmean, 9-11 mg/L) for pain relief in neonates compared to older children and adults, dosing regimens based on this Cssmean were evaluated in a two-step approach.
    First, a systematic search was performed to provide pharmacokinetic (PK)-based dosing guidelines for pain in neonates (with subsequent searches on safety in these papers). Second, concentration-time profiles based on these dosing guidelines were generated to provide a dosing advice for paracetamol to treat neonatal pain.
    Of 2334 potentially relevant articles, 9 studies were included. For typical term neonates, dosages specified in packaging (labels) resulted in Cssmean below target (7.65 mg/L), while dosages from investigator-initiated studies resulted in either a Cssmean above (15.31), or around the target (11.78 and 10.21) for (pre)term neonates >32 weeks. Only one study suggested a dosing resulting in a tailored concentration (8.7) in preterm neonates <32 weeks.
    A loading dose 20 mg/kg, followed by 10 mg/kg/6h is recommended for 32-44 weeks\' neonates, which is supported by short-term safety. For neonates < 32 weeks, a loading dose of 12 mg/kg and a maintenance dose of 6mg/kg/6h seems to lead to the target Cssmean, though additional clinical studies are needed to support its safety.

    目的:大剂量静脉注射免疫球蛋白(IVIg)治疗严重的皮肤自身免疫性疾病和中毒性表皮坏死松解症(TEN)是皮肤病学中公认的方法。由于IVIg治疗通常考虑用于罕见的临床实体或严重病例,免疫球蛋白的使用通常不基于循证医学通常需要的随机对照试验的数据.由于使用IVIg的适应症很少,在可预见的将来,此类研究不太可能提供。因为一线使用受到IVIg高成本的限制,首个关于在皮肤病中使用IVIg的临床指南于2008年制定,2011年更新.
    方法:这里介绍的欧洲指南是由EDF和EADV提名的专家小组编写的。制定该指南是为了更新目前认为有效的治疗适应症,并总结在皮肤自身免疫性疾病和TEN中使用IVIg的证据。
    结论:当前的指南代表了关于IVIg使用的专家意见和定义,反映了当前已发表的证据,旨在作为在皮肤病中使用IVIg的决策工具。
    OBJECTIVE: Treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe cases, the use of immunoglobulin is not generally based on data from randomized controlled trials usually required for evidence-based medicine. Since the indications for the use of IVIg are rare, it is unlikely that such studies will be available in the foreseeable future. Because first-line use is limited by the high costs of IVIg, the first clinical guidelines on the use of IVIg in dermatological conditions were established in 2008 and renewed in 2011.
    METHODS: The European guidelines presented here were prepared by a panel of experts nominated by the EDF and EADV. The guidelines were developed to update the indications for treatment currently considered effective and to summarize the evidence for the use of IVIg in dermatological autoimmune diseases and TEN.
    CONCLUSIONS: The current guidelines represent consensual expert opinions and definitions on the use of IVIg reflecting current published evidence and are intended to serve as a decision-making tool for the use of IVIg in dermatological diseases.

    Despite current recommendations on the management of pre-operative anaemia, there is no pragmatic guidance for the diagnosis and management of anaemia and iron deficiency in surgical patients. A number of experienced researchers and clinicians took part in an expert workshop and developed the following consensus statement. After presentation of our own research data and local policies and procedures, appropriate relevant literature was reviewed and discussed. We developed a series of best-practice and evidence-based statements to advise on patient care with respect to anaemia and iron deficiency in the peri-operative period. These statements include: a diagnostic approach for anaemia and iron deficiency in surgical patients; identification of patients appropriate for treatment; and advice on practical management and follow-up. We urge anaesthetists and peri-operative physicians to embrace these recommendations, and hospital administrators to enable implementation of these concepts by allocating adequate resources.
