RESUMEN
BACKGROUND: Long peripheral catheters (LPCs) role in Difficult IntraVenous Access (DIVA) patients admitted to the emergency department has already been studied, resulting in a rapid, safe, and cost-effective procedure. Although their use in outpatient settings is established, there is a lack of studies assessing their benefits. In particular, rheumatologic outpatients affected by scleroderma, especially those affected by digital ulcers, are often treated with intravenous infusions of prostaglandin I2 (PGI2) analog (IV-PGI2A). OBJECTIVE AND METHODS: From 1 October 2021 to 31 March 2024, we conducted a prospective study enrolling DIVA outpatients affected by systemic sclerosis or undifferentiated connective tissue disease who needed IV-PGI2A therapy at L. Sacco Hospital in Milan (Italy). Each treatment cycle consisted of four consecutive days of infusion of iloprost or alprostadil. The primary aim was to assess the efficacy and potential complications associated with LPCs for IV-PGI2A. RESULTS: Twenty-six patients were enrolled 23 were females (88.5%), and the median age was 72 years (IQR 56-78.7). In total, 97 LPCs were inserted, with a mean number of insertions per patient/year of 2.3. An increase in LPCs insertion during the 30 months of the enrollment period was observed. Eighteen patients required more than one LPC placement, and in 61% of them, the second venipuncture was executed at a different site. No procedural complications were registered (accidental puncture of the brachial artery, accidental median nerve puncture, bleeding) nor late complications (Catheter-Related Thrombosis, Catheter-Related Bloodstream Infections, Accidental Removal). CONCLUSIONS: Our experience shows that LPCs could be valuable and safe for rheumatologic outpatients. The increased number of insertions and new and total patients enrolled each year defines the satisfaction of patients and health care professionals.
RESUMEN
Objective To investigate the appropriate venous access for obese patients undergoing metabolic and bariatric surgery by comparing the clinical outcomes of different lengths of peripheral intravenous catheters.Methods Inpatients who underwent bariatric surgery in a tertiary hospital in Zhejiang from August 2022 to December 2022 were selected as the study population using a fixed-point continuous convenience sampling method.A stratified block randomisation method was used to divide the group into an experimental group 1(mini-midline catheters),an experimental group 2(midline catheters)and a control group(short peripheral intravenous catheters,Short PIVCs).The incidence of catheter-related complications,the rate of extubation due to complications,the duration of catheter retention,the time to first catheter-related complication were compared in the 3 groups.Results A total of 186 patients were included,with 62 patients in each group.The overall incidence of catheter-related complications in experimental group 1,experimental group 2,and control group were 25.81％,8.06％,and 58.06％.The extubation rates due to complications were 19.35％,4.84％,and 41.94％,and the duration of catheter retention was 7.00(6.00,7.00)d,7.00(6.00,7.00)d,6.00(3.00,6.25)d.The differences were statistically different(P＜0.05)when comparing the 3 groups.Among them,the differences in the overall incidence of catheter-related complications and the rate of extubation due to complications were statistically significant when comparing experimental group 1 with the control group,experimental group 2 with the control group,and experimental group 1 with experimental group 2(P＜0.017);the duration of catheter retention in both experimental group 1 and experimental group 2 were higher than it in the control group,and the differences were statistically different(P＜0.017).Conclusion The complication rate of mini-midline catheters and midline catheters is lower than that of short ones,and the indwelling time is consistent with the perioperative period of metabolic and bariatric surgery,which is suitable for use in patients undergoing metabolic and bariatric surgery.
RESUMEN
Objective To search,evaluate,and summarize the best evidence of insertion and maintenance of mini-midline in adult patients,in order to provide a solid evidence-based foundation for establishing clinical standardized and safe utilization of mini-midline.Methods We systematically searched UpToDate,BMJ Best Practice,Guideline International Network,National Guideline Clearinghouse,Joanna Briggs Institute,National Institute for Health and Care Excellence,Centers for Disease Control and Prevention,Scottish Intercollegiate Guidelines Network,Canadian Medical Association:Clinical Practice Guideline,Registered Nurses'Association of Ontario,Intravenous Nurses Society,Cochrane Library,PubMed,CINAHL,Embase,Web of Science,Yimaitong,China National Knowledge Infrastructure,Wanfang Database,and China Biomedical Literature Database.It includes clinical practice guidelines,expert consensuses,evidence summaries,systematic reviews,meta-analyses,and best practice on mini-midline insertion and maintenance.The search period covered January 2013 to May 2023.2 researchers independently evaluated the literature quality and extracted the literature that met the standards.The evidence was graded using the JBI evidence pre-grading system(2014),and the extracted evidence was classified and summarized by themes.Results A total of 10 pieces of the literature were involved,including 6 guidelines,2 expert consensuses,and 2 systematic reviews.This study summarized 20 pieces of best evidence in relation to the following 4 themes:indications and contraindications for mini-midline,catheter insertion,catheter maintenance and catheter removal.Conclusion The study comprehensively and scientifically summarizes the best evidence regarding the insertion and maintenance of mini-midline.We recommend that clinical practitioners integrate this evidence into their practice,while considering individual patient preferences and medical contexts.This approach,in line with the principle of individualization,will contribute to enhancing the standardization and safety of mini-midline use in clinical settings.
RESUMEN
BACKGROUND: In the daily management of peripheral venous access, the health emergency linked to the COVID-19 pandemic led to re-examining the criteria for choosing, positioning and maintaining the different types of peripheral venous access. OBJECTIVES: This study aimed to observe the dwell time of long peripheral cannula (LPC, also known as mini-midline) in patients affected by COVID 19 related pneumonia. The secondary objective is to study any complications due to mini-midline insertion. MATERIALS AND METHODS: We conducted a prospective observational study on COVID19 patients who arrived at our Semi-Intensive Respiratory Unit from territorial ED between January and April 2021, to whom were positioned an LPC at the time of admission following the SIPUA protocol (Safe Insertion of Peripheral Ultrasound-guided Access). We used Vygon™ Leader-Cath© 18G in polyethylene and 8 cm long catheter. RESULTS: We enrolled 53 consecutive patients, reaching 769 catheter days. The procedure was performed without immediate complications in 37 patients out of 53 (69.8%). In 14 patients (26.4%), we observed a local hematoma (no one led to a failure or early removal of the device) and in two patients (3.7%) was not possible to draw blood. The average catheter dwell time was 14.5 days, from 3 to 41 days. In 42 patients (79.2%), the device was removed at the end of use. In 11 patients out of 53 (20.8%), the device was removed early due to complications: seven accidental removals, one obstruction, two vein thrombosis, and one superficial thrombophlebitis. CONCLUSIONS: The ultrasound-guided implantation of an 18G LPC in COVID19 patients, regardless of the state of their venous heritage, would seem to be an excellent strategy for these patients, reducing the number of venipunctures and CVC implantation, as well as allowing multiple and high pressure (contrast) infusions.
RESUMEN
BACKGROUND: Achieving a reliable venous access in a particular subset of patients and/or in emergency settings can be challenging and time-consuming. Furthermore, many hospitalized patients do not meet the criteria for central venous catheter positioning, unless an upgrade of the treatment is further needed. The mini-midline catheter has already showed to be reliable and safe as a stand-alone device, since it is easily and rapidly inserted and can indwell up to 1 month. METHODS: In this further case series, we retrospectively evaluated data from 63 patients where a previously inserted mini-midline catheter was upgraded to a central venous catheter (the devices inserted in the arm replaced by peripherally inserted central catheter and others inserted "off-label" in the internal jugular replaced by single lumen centrally inserted central catheter), being used as introducer for the Seldinger guidewire. RESULTS: The guidewire replacement was been made even early (after 1 day) or late (more than 10 days), usually following a need for an upgrade in treatment. No early or late complications were reported. CONCLUSION: According to the preliminary data we collected, this converting procedure seems to be feasible and risk-free, since neither infectious nor thrombotic complications were reported.

BACKGROUND: "Difficult intravenous access" patients represent a challenge within an emergency department as they often require many attempts to insert a peripheral short cannula in the emergency room or during the whole hospitalization. This can lead to many problems in terms of patient discomfort, increase of cost, and prolonged treatment time. OBJECTIVES: This study aimed to reduce the number of attempts needed for a short-cannula insertion or preventing insertion of a central vascular access by placing an ultrasound-guided long cannula during the emergency department visit. MATERIAL AND METHODS: The insertion of mini-midline was monitored within an emergency room in 50 patients considered difficult intravenous access patients, who failed two attempts at peripheral venous access insertion and/or required the use of an alternative vascular device. RESULTS: A total of 46 patients out of 50 were monitored. In 38 (82%) patients, the device was removed due to the end of the indication, and in six of them, it was replaced by a central venous catheter. Two devices were left inside even after discharge and were then removed at the end of indication. In eight (17%) patients, the device was removed due to accidental removal (4) and malfunction (4). In all the cases, the average duration of the insertion procedure was 10 min. The mean dwell time accounted to 7 and 9 days. CONCLUSION: The insertion of a mini-midline as part of the first emergency room visit in selected patients is a rapid, safe, and cost-effective procedure, which can provide the patient with stable venous access during the all hospitalization time.
