“Intraosseous administration of tenecteplase for thrombolysis of an acute ischemic stroke”

IntroCurrent guidelines for acute ischemic stroke recommend timely administration of intravascular thrombolytic therapy to promote functional and neurologic outcomes. Tenecteplase is an emerging off-label therapy for this indication and being utilized by various institutions due to its simpler administration strategy. In emergent situations in which intravenous access cannot be obtained, intraosseous access is a viable option for medication administration. However, there has been minimal published cases to support the efficacy and safety of intraosseous administration of tenecteplase for acute ischemic stroke. CaseWe describe the case of a 51-year-old woman who developed acute ischemic stroke within our institution. Due to difficulty achieving intravenous access and time-dependent efficacy of thrombolytic therapy, the decision was made to administer tenecteplase by the intraosseous route. Stroke symptoms improved within 48 hours following administration without complication. ConclusionIntraosseous administration of tenecteplase may be considered for treatment of acute ischemic stroke if intravenous access is unattainable.

The effect of a pushing technique with normal saline on peripheral intravenous catheter placement success in paediatric haematology and oncology: A randomized controlled trial

PurposeThe aim of the present study is to determine the effect of the pushing technique with saline on the success of peripheral IV catheter placement in a paediatric haematology and oncology sample. MethodsThe randomized controlled trial was conducted among 60 paediatric haematology and oncology patients aged between 0 and 17. The participants were randomly assigned to two peripheral intravenous catheter placement groups (intervention group, n:30, control group, n:30). Each patient was evaluated with the Difficult Intravenous Access (DIVA) score before being included in the study. Each patient was assessed using the Personal Information Form for Children and Catheter Registration Form. ResultsThe average age of the children was 86.4 months (SD = 60.0); 36.7% were female. The pushing technique with saline significantly increased the success of placing a peripheral IV catheter on the first attempt in the intervention group compared to the control group (F = 42.391, p = 0.000). The number of attempts during peripheral IV catheter placement significantly decreased in the intervention group compared with the control group (t = −5.676, p = 0.000). Complications were less in the intervention group compared with the control group (χ2 = 24.438, p = 0.000). The procedure time was significantly shorter in the intervention group compared with the control group (t = −4.026, p = 0.000). ConclusionThe pushing technique with saline is an effective method to increase the first attempt success rate, decrease the number of attempts, reduce the procedure time, and reduce the complications during peripheral intravenous catheter placement procedures in paediatric haematology and oncology patients with difficult intravenous access. Trial RegistrationThis study was registered at ClinicalTrials.gov (NCT05685290 & date of first recruitment: January 3, 2023) https://clinicaltrials.gov/ct2/show/NCT05685290.

Expert consensus on safety management of vascular access devices for patients with digestive system cancer (2024)

The rational selection and standardized management of vascular access devices is an urgent issue in the treatment of digestive system cancer. The purpose of this consensus is to develop solutions for the safe management of intravenous vascular access devices for patients with digestive system cancer and to provide evidence for clinical decision-making. This consensus is developed by a group of experts from multiple-disciplines in China International Exchange and Promotive Association for Medical and Health Care Clinical Nutrition Health Branch, Clinical Nutrition Branch of Chinese Nutrition Society, Chinese Society for Parenteral and Enteral Nutrition. It is based on the best current evidence and combined with Chinese clinical practice experience. The recommendations were discussed and on the following topics: how to choose vascular access devices for patients with digestive system cancer; optimal selection of puncture sites and positioning of the tip for peripherally inserted central catheters; prevention and management of complications post-central venous catheterization; strategies for prevention and treatment of central venous catheter occlusion; criteria for central venous catheter removal; indications for the use of venous port access and criteria for peripheral venous catheter in patients with digestive system cancer.

Evaluation of Predictors Associated with Slow Clinical Response with Extension of Outpatient Parenteral Antimicrobial Therapy

Background: Outpatient parenteral antimicrobial therapy (OPAT) provides a safe and effective alternative to prolonged hospitalization for patients with infectious diseases requiring elongated antimicrobial therapy. One study found that 35.6% of OPAT episodes met the composite definition for treatment failure, with unplanned extension of OPAT as the most common reason for treatment failure. Our study sought to identify factors predicting higher likelihood of extension of OPAT due to slow clinical response to treatment and determine how therapy extension relates to complications. Method: This retrospective cohort study included all patients aged ≥18 years discharged on OPAT between April 2022 and October 2022. Demographic, treatment, outcome, and complications data were extracted through chart review. The primary outcome was the proportion and predictors of OPAT extension due to slow clinical response to treatment. The secondary outcomes were OPAT complication rate, 30-day ED visit and 30-day readmission rates related to OPAT complications. We used univariable and multivariable logistic regression models for the primary outcome of slow clinical response requiring OPAT extension. Variables with p < 0.1 in the univariable analyses were included in the multivariable model. Result: 231 patients received OPAT during the six-month study. Among them, 40 (17.3%) patients required an extension of therapy. In univariable analysis, patients who had slow clinical response requiring extension of OPAT were more likely to have intraabdominal infection (odds ratio [OR], 2.435; 95% confidence interval[CI], 1.053–5.628), receipt of metronidazole (OR, 3.729; 95% CI, 1.413–9.842), and were more likely to be followed up through office visit (OR, 5.033; 95%CI, 1.164–21.759) or combination of office visit and telemedicine (OR, 2.223; 95%CI 1.041–4.747). Other variable comparisons are detailed in Figure 1. In the multivariable regression analysis, the independent predictor associated with extended of OPAT was follow-up via office visit (adjusted OR, 4.630; 95% CI, 1.024-20.694). Rates of complications related to intravenous access and antibiotic were similar between patients with and without extension; 15% vs. 11% (p=0.430) and 7.5% vs. 7.3% (p=1.000), respectively. There were no significant differences in 30-day ED visits and readmission rates between the 2 groups: 7.5% vs. 5.8%(p=0.715) and 12.5% vs. 7.3% (p=0.338). Conclusion: Our study highlights patient’s office visit follow-up is associated with the OPAT extension due to slow clinical response. However, extended therapy did not result in a significant increase in complications or hospital readmissions. These findings suggest the importance of careful patient selection and monitoring for OPAT, potentially guiding more efficient and targeted healthcare practices.

Comparison of intranasal dexmedetomidine and ketamine for paediatric premedication: A randomized study

Introduction and objectivesPaediatric patients are given premedication in order to decrease preoperative anxiety, allow smooth induction, and prevent postoperative psychological insult and behavioural changes. A child friendly method of administration is desirable.We compared intranasal administration of dexmedetomidine and ketamine in the operating room environment, to evaluate the Faces, Legs, Activity, Cry and Consolability (FLACC) score at the time of establishing intravenous access for induction of general anaesthesia. MethodsThis prospective, double-blind, randomized controlled trial was conducted at a tertiary care center. One hundred patients, 2–10 years of age, ASA physical status 1 & 2, scheduled for general anaesthesia were enrolled. Patient’s presedation behaviour was assessed by the modified Yale Preoperative Anxiety Scale Short Form (mYPAS-SF). Patients in Group D received Dexmedetomidine 1 mcg/kg intranasally, and patients in Group K received Ketamine 5 mg/kg intranasally. After 45 min, patients were transferred to the operating table where intravenous cannulation was carried out and the response to needle insertion was assessed by FLACC scale. Vital signs, including the pulse-oximetry, heart rate and respiratory rate were monitored. Side effects such as nausea, vomiting, and agitation were also recorded. ResultsA significantly higher FLACC score was seen in Group D as compared to Group K (p = 0.001). The mean heart rate between two groups was found to be significantly (p = 0.001) lower in Group D compared to Group K. However, the proportion of adverse events was 8% in patients who received ketamine. ConclusionsIntranasal ketamine in a dose of 5 mg/kg is clinically more effective as premedication in children aged 2–10 years in comparison with intranasal dexmedetomidine in a dose of 1 mcg/kg.

Association between tunneled catheter placement and catheter‐associated deep venous thrombosis in adults with inflammatory bowel disease receiving home parenteral nutrition: A retrospective cohort study

AbstractBackgroundPatients with inflammatory bowel disease (IBD) are at increased risk of thrombosis. They often need parenteral nutrition (PN) requiring intravenous access for prolonged periods. We assessed the risk of deep vein thrombosis (DVT) associated with peripherally inserted central catheters (PICCs) and tunneled catheters for patients with IBD receiving home PN (HPN).MethodsUsing the Cleveland Clinic HPN Registry, we retrospectively studied a cohort of adults with IBD who received HPN between June 30, 2019 and January 1, 2023. We collected demographics, catheter type, and catheter‐associated DVT (CADVT) data. We performed descriptive statistics and Poisson tests to compare CADVT rates among parameters of interest. We generated Kaplan‐Meier graphs to illustrate longevity of CADVT‐free survival and a Cox proportional hazard model to calculate the hazard ratio associated with CADVT.ResultsWe collected data on 407 patients, of which, 276 (68%) received tunneled catheters and 131 (32%) received PICCs as their initial catheter. There were 17 CADVTs with an overall rate of 0.08 per 1000 catheter days, whereas individual rates of DVT for PICCs and tunneled catheters were 0.16 and 0.05 per 1000 catheter days, respectively (P = 0.03). After adjusting for age, sex, and comorbidity, CADVT risk was significantly higher for PICCs compared with tunneled catheters, with an adjusted hazard ratio of 2.962 (95% CI=1.140–7.698; P = 0.025) and adjusted incidence rate ratio of 3.66 (95% CI=2.637–4.696; P = 0.013).ConclusionOur study shows that CADVT risk is nearly three times higher with PICCs compared with tunneled catheters. We recommend tunneled catheter placement for patients with IBD who require HPN infusion greater than 30 days.

A Fatal Case of Powassan Virus Encephalitis

The Powassan virus (POWV) is part of the Flaviviridae family. It is mainly transmitted via tickbite but can rarely be spread person-to-person through blood transfusions. Initial symptoms include fever, headache, and vomiting. It can cause severe symptoms, including confusion, aphasia, and seizures. Approximately 1 out of 10 people with severe disease die. From 2010 to 2020, 194 Powassan virus cases have been reported to the Center for Disease Control (CDC), with 22 of them resulting in death. In this case report, we discuss a 39-year-old female who presented with fever, myalgia, and confusion. During her hospitalization, she developed tonic-clonic seizures, which required sedation and intubation. A central venous catheter was inserted due to poor intravenous access, and in the process of placing it, the provider sustained a needle stick injury. The patient was eventually diagnosed with POWV encephalitis and transferred to a higher level of care, where a brain perfusion study showed an absence of brain flow consistent with brain death. After a discussion with the family, the decision was made to extubate the patient terminally. The provider who sustained the needle stick injury reported no concerning symptoms two years after the event.

The Efficacy of Intraosseous Access for Initial Resuscitation in Patients with Severe Trauma: A Retrospective Multicenter Study in South Korea.

Background/Objective: In patients with severe trauma, intraosseous (IO) access is an alternative when intravenous (IV) access proves challenging. However, detailed insights into its utilization patterns and effectiveness are lacking. This study aims to evaluate the use and efficacy of IO access in hemodynamically unstable patients with trauma at level-1 trauma centers in South Korea. Methods: Data from six centers over 12 months were analyzed, focusing on patients with traumatic cardiac arrest or shock. Overall, 206 patients were included in the study: 94 in the IO group and 112 in the IV group. Results: The first-attempt success rate was higher in the IO group than in the IV group (90.4% vs. 75.5%). The procedure time in the IO group was also shorter than that in the IV group. The fluid infusion rate was lower in the IO group than in the IV group; however, the use of a pressure bag with IO access significantly increased the rate, making it comparable to the IV infusion rate. Further, regarding IO access, a humeral site provided a higher infusion rate than a tibial site. Conclusions: IO access offers a viable alternative to IV access for the initial resuscitation in patients with trauma, providing advantages in terms of procedure time and first-attempt success rate. The use of a pressure bag and a humeral site for IO access afforded infusion rates comparable to those associated with IV access.

The efficacy of technology-based devices on the first-attempt success rate for difficult intravenous access in pediatrics: A systematic review and network meta-analysis.

Previous studies have compared various technology-based devices, such as ultrasonography (USG), near-infrared (NIR), and transilluminator (TI), with standard care (SC) to facilitate peripheral intravenous cannulation (PIVC) in pediatric patients. This study aims to investigate the efficacy of these interventions on the first-attempt success rate (FASR) of PIVC in pediatric patients with difficult intravenous access (DIVA) using network meta-analysis (NMA). We conducted a comprehensive literature search in databases to identify randomized clinical trials comparing the effects of different devices on the FASR of PIVC from inception until August 2023. Pooled relative risks with 95% credible intervals were estimated using pairwise and network meta-analysis with random effects. To rank the efficacy of devices, we calculated the probabilities of the surface under the cumulative ranking curve (SUCRA). A total of 18 studies were included in the final analysis. The results of pairwise meta-analysis showed that the use of devices increased the FASR for PIVC by 13% (RR: 1.13, 95% CI: [0.98, 1.30]) compared to SC. The ranking of interventions based on efficacy from highest to lowest was as follows: USG (SUCRA: 1), NIR (SUCRA: 0.6), SC (SUCRA: 0.3), and TI (SUCRA: 0.1), with a very low confidence estimate. Based on our findings, the prioritization of device usage to increase the FASR of PIVC in pediatric patients with DIVA is as follows: USG, NIR, SC, and TI, respectively. However, due to inconsistencies in the network, existence of an overall high risk of bias in the included studies, and very low confidence estimate, further clinical trials are required.

What is the Evidence for Using Intranasal Medicine in the Prehospital Setting? A Systematic Review

Objectives Intranasal (IN) medications offer a safe non-invasive way to rapidly deliver drugs in situations where intravenous (IV) access and intramuscular (IM) administration is challenging or not feasible. In the prehospital setting, this can be an essential alternative in time critical situations including trauma management, seizures, and agitated patients. However, there is a paucity of evidence summarizing its efficacy in this environment. This systematic review aims to assess the current evidence supporting the use of IN medicine (midazolam, ketamine, fentanyl, morphine, glucagon, and naloxone) in the prehospital setting alone. Methods A systematic literature search (PROSPERO CRD42023440713) of PubMed, Web of Science, OVID Medline, “Cochrane Central Register of Controlled Trials,” Cochrane reviews and Embase was performed from inception to June 2023 to identify studies where IN medications were administered to patients in the prehospital setting. All randomized controlled trials, observational cohort studies, case series, and case reports were included. Papers not written in English, review articles, abstracts, and non-published data (including letters to the editor) were excluded. The methodological quality of the included studies was interpreted using the Cochrane risk of bias tool and rated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. No funding was received. Results From 4818 studies, 39 were included (seven for midazolam, five for ketamine, twelve for fentanyl, one for diamorphine, two for glucagon, and twelve for naloxone). A total of 24,097 patients were treated with IN medications across all the studies. There were five moderate quality, four low quality, and thirty very low quality studies. The potential efficacy of IN fentanyl and ketamine was demonstrated consistently throughout the studies with less clear evidence for midazolam, morphine, glucagon, and naloxone. This review was severely limited by the study quality, with most studies demonstrating “high concerns” for bias. Conclusions Prehospital IN medication administration has wide-ranging potential, particularly for administering analgesia. There are likely to be certain populations, for example, pediatrics, that will benefit the most, although conclusions are limited by the quality of evidence currently available. We encourage additional research in this area, particularly with robust prospective double-blind RCTs.

Long peripheral catheters for intravenous infusions of iloprost or alprostadil therapy in rheumatologic outpatients.

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). 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. 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). 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.

Doppler Ultrasound and Resistive Indices in the Diagnosis of Ureteropelvic Junction Obstruction in the Pediatric Population.

Mercapto acetyl tri-glycine renogram (MAG3) scan has been the gold standard assessment of pediatric ureteropelvic junction obstruction (UPJO) but requires intravenous access and radiation exposure. While Doppler ultrasound measurements of resistive indices (RI) of the arcuate arteries have been proposed as an alternative assessment of obstruction, they have not been widely adopted in the pediatric population. We hypothesized that RI of the main renal artery (RA) is more strongly correlated with MAG3 findings than arcuate RI. Pediatric patients with unilateral Society for Fetal Urology grade 3-4 hydronephrosis undergoing concomitant RUS and MAG3 were recruited. Doppler ultrasound peak systolic velocity (PSV); RI of bilateral RA at the origin, middle, and hilum; and RI of the superior, middle, and lower pole arcuate arteries were obtained. MAG3 differential renal function (DRF) and T½ were recorded. Differences in RI measurements (DRI) between the affected and normal kidney were calculated and compared with DRF and T½. 31 patients (median 4.6-month-old) were enrolled. Only RA RI at the origin differed between affected and normal kidneys (p < .001). DRI RA at the origin showed weak evidence for an association with MAG3 DRF < 40% (p .07). DRI was not associated with T½ > 20 minutes. There was weak evidence for an association between RA DRI at the origin and DRF but not with T½. These findings suggest that RA DRI may provide additional data in the evaluation of patients with UPJO to tailor the use of MAG3 and associated risk of radiation exposure to those patients most at risk for concomitant renal function impairment.

Impact of intravenous accessibility and prehospital epinephrine use on survival outcomes of adult nontraumatic out-of-hospital cardiac arrest patients

BackgroundThis study compared out-of-hospital cardiac arrest (OHCA) patient outcomes based on intravenous (IV) access and prehospital epinephrine use.MethodsA retrospective study in Ulsan, South Korea, from January 2017 to December 2022, analyzed adult nontraumatic OHCA cases. Patients were grouped: Group 1 (no IV attempts), Group 2 (failed IV access), Group 3 (successful IV access without epinephrine), and Group 4 (successful IV access with epinephrine), with comparisons using logistic regression analysis.ResultsAmong 2,656 patients, Group 4 had significantly lower survival to hospital discharge (adjusted OR 0.520, 95% CI 0.346–0.782, p = 0.002) and favorable neurological outcomes (adjusted OR 0.292, 95% CI 0.140–0.611, p = 0.001) than Group 1. Groups 2 and 3 showed insignificant survival to hospital discharge (adjusted OR 0.814, 95% CI 0.566–1.171, p = 0.268) and (adjusted OR 1.069, 95% CI 0.810–1.412, p = 0.636) and favorable neurological outcomes (adjusted OR 0.585, 95% CI 0.299–1.144, p = 0.117) and (adjusted OR 1.075, 95% CI 0.689–1.677, p = 0.751). In the shockable rhythm group, Group 3 had better survival to hospital discharge (adjusted OR 1.700, 95% CI 1.044–2.770, p = 0.033).ConclusionsSuccessful IV access with epinephrine showed worse outcomes in both rhythm groups than no IV attempts. Outcomes for failed IV and successful IV access without epinephrine were inconclusive. Importantly, successful IV access without epinephrine showed favorable survival to hospital discharge in the shockable rhythm group, warranting further research into IV access for fluid resuscitation in shockable rhythm OHCA patients.

Femoral to abdomen tunneling at the bedside for medium/long term venous access.

Femoral to abdomen tunneling of small-bore central venous catheters is a bedside technique for patients with contraindications to a thoracic approach, or as an alternative to a lower extremity catheter exit site. A femoral to abdomen tunneling technique was implemented for patients receiving medium and long-term intravenous treatments with contraindications to the thoracic venous approach or as an alternative to a lower extremity catheter exit site. All venous access devices were inserted with ultrasound guidance under local anesthesia, and catheter tip placement assessed by post procedural radiography. In this case series, from January 2020 to January 2023, a total of eight FTA-tunneled venous access devices were inserted. There were seven ambulatory patients and one bedbound patient. The median length of the subcutaneous tunnel was 20 cm, ranging from 15 to 27 cm. The median length of the intravenous catheter to the terminal tip was 31 cm, ranging from 23 to 40 cm. Tip location was confirmed by post-procedural abdominal radiograph. The catheter tip locations were interpreted to be at the level of T8-T9 (2), T12 (1), L4 (2), L2 (2), L1(1).No insertion or post insertion related complication was reported. Six patients completed the scheduled intravenous treatment. One patient was unable to be tracked due to transfer to an outside facility. One catheter initially demonstrated to be coiled over the left common iliac vessel was repositioned using a high flow flush technique. There was one reported catheter dislodgment by the nurse providing care and maintenance. The overall implant days were 961, with a median dwell time of 125 days ranging from 20 to 399 days. Femoral to abdomen tunneling provides an alternative exit site useful in select patients with complex intravenous access. The data of this small retrospective review suggests this a safe and minimally invasive bedside procedure.

Poland's first vascular access team 3-year analysis: Insights and learnings.

During the COVID-19 pandemic, Poland saw a surge in interest in midline catheters (MCs) and Long Peripheral Catheters (LPCs) for intravenous therapy. Before this, MCs were not extensively utilised in the country, and there was no formally established Polish vascular access team. MCs, which have been used for years in many countries, are now becoming increasingly common in Poland. This study aimed to analyse the use of MCs in a 3-year perspective of their introduction in daily clinical practice based on a nurse-led Vascular Access Team (VAT). The records of adult patients who received intravenous therapy with 727 MCs and 293 LPCs from January 2021 to December 2023 at the University Clinical Centre of the Medical University of Warsaw were analysed. The main indication for cannulation was expected intravenous therapy over 5 days (81.66%, n = 833), of which 71.37% (n = 728) of patients in this group had concomitant difficult intravenous access (DIVA). Over 6 years, centrally inserted central catheters (CICCs) inserted due to DIVA were reduced from n = 108 in 2017 to n = 18 in 2023. The end of intravenous therapy was the reason for the removal of 64.6% of catheters (n = 659), including death and switch to CICCs as well. Complications leading to premature removal accounted for 31.2%, such as: occlusion (14.6%), patient self-removal (7.1%) and thrombosis (3.43%). The introduction of MCs as a possible option for peripheral venous access reduces the use of CVCs. Developing MCs programmes should be based on investing in staff competencies, which increases success rates. The nurses and physicians should be trained in infusion care to achieve better results in the use of MCs and LPCs. Increasing the competence of nurses in Poland is necessary for the implementation of full-service and top-level functioning of VAT.

Optimizing Intravenous Access for Long-Term Parenteral Nutrition.

Securing safe and effective intravenous (IV) access is of utmost importance for administering parenteral nutrition (PN). Sustaining this access can indeed pose challenges, especially when dealing with the risk of complications associated with long-term PN. This review emphasizes best practices to optimize intravenous access and reviews the current evidence-based recommendations and consensus guidelines. An individualized approach when selecting central venous catheters (CVC) is recommended, considering the estimated duration of need for IV access and the number of lumens needed. Established and novel approaches to minimize complications, including infection and thrombosis, are recognized. These include placement and positioning of the catheter tip under sonographic guidance and the use of antimicrobial lock therapies. Moreover, when possible, salvaging CVCs can reduce the risk of vascular access loss. CVC selection for patients requiring PN depends on several factors. Carefully reviewing an individual patient's clinical characteristics and discussing options is important. Given the increased infection risk, CVC lumens should be minimized. For long-term PN beyond 6months, using CVCs with skin barriers and larger diameters should be considered.
