iv cannulation

Simulation-based medical education (SBME) offers a secure and controlled environment for training in ultrasound-related clinical skills such as nerve blocking and intravenous cannulation. Sonographer training for point-of-care ultrasound often adopts the train-the-trainer (TTT) model, wherein a select group of sonographers receive on-site training to subsequently instruct others. This model traditionally relies on expensive commercial ultrasound simulators, which presents a barrier to the scale-up of the TTT model...

OBJECTIVE: FFA is a well-established investigation for the diagnosis of optic nerve abnormalities, requiring an intravenous cannula and extended imaging acquisition time. Cannulation can present a challenge in paediatric patients and whilst oral FFA has been used for decades, it has been limited by imaging technology and unconfirmed image acquisition timings. For years, we have used a modern ultra-widefield retinal camera, and established imaging time-points to demonstrate dynamic optic nerve head changes upon ingestion of fluorescein and collected a database of oFFA images for various presentations...

BACKGROUND: Legionella remains underdiagnosed in the intensive care unit and can progress to acute respiratory distress syndrome (ARDS), multiorgan failure and death. In severe cases, venovenous extracorporeal membrane oxygenation (VV-ECMO) allows time for resolution of disease with Legionella-targeted therapy. VV-ECMO outcomes for Legionella are favorable with reported survival greater than 70%. Rapid molecular polymerase chain reaction (PCR) testing of the lower respiratory tract aids in diagnosing Legionella with high sensitivity and specificity...

BACKGROUND: Peripheral venous cannulation is one of the most common procedures in medicine. A larger cannula allows higher rates of fluid to be provided if needed in a deteriorating patient; however, it is also perceived that larger-gauge cannula placement is associated with increased pain and procedural difficulty. OBJECTIVE: This study aimed to compare the pain and procedural difficulty experienced during insertion between 18-gauge (18G) and 20-gauge (20G) cannulas...

INTRODUCTION: Superficial arteries, such as radial and dorsalis pedis arteries, are commonly cannulated for invasive blood pressure monitoring. Failure to cannulate these arteries necessitates alternate arteries, such as the posterior tibial artery (PTA). The deep-seated anatomy of PTA makes arterial cannulation precarious by the palpatory technique. Ultrasound guidance during PTA cannulation may overcome this problem. With this background, we evaluated the ultrasound-guided (USG) versus palpatory method for PTA cannulation with respect to the first attempt's success and number of attempts...

In massive pulmonary embolism (PE), anticoagulation and thrombolytics may increase the risk of retroperitoneal bleeding following vascular cannulation for extracorporeal hemodynamic support resulting in abdominal compartment syndrome (ACS). A 27-year-old women at 33 weeks of gestation presented with acute chest pain and shortness of breath. Massive PE was diagnosed. Intravenous unfractionated heparin was started together with catheter-directed tissue plasminogen activator (tPA) infusion and mechanical thrombectomy...

Capability is the ability to perform clinical skills in ever-changing real world contexts, adapting to challenges and integrating technical and non-technical skills and competencies, for example, cannulating an uncooperative patient at night. Going beyond teaching competency and ensuring capability is imperative, as recommended by the national outcomes for medical graduates. A course on intravenous cannulation was developed with e-learning modules and high-fidelity complex simulation scenarios, aiming to promote capability in practice...

BACKGROUND: The application of splints is one of the most used methods to prolong the life span of peripheral intravenous cannulation (PIVC). OBJECTIVE: To assess the effect of splint application on the functional duration of PIVC in neonates. METHODS: This systematic review and meta-analysis identified, appraised, and synthesized available evidence from randomized and quasi-randomized controlled trials (RCT) related to the effects of splint application compared to no splinting on the functional duration of PIVC and its associated complications in term and preterm neonates...

Obtaining adequate vascular access is imperative for effective resuscitative, therapeutic, and diagnostic interventions. The intraosseous (IO) route is indicated when immediate vascular access is needed, and standard central or peripheral intravenous (IV) access is unattainable or would delay therapy in a critical patient. We present a rare case of improper IO line placement in the right proximal tibia of a 30-year-old female involved in a motor vehicle collision, resulting in extravasation of blood products into the surrounding tissue and development of acute compartment syndrome...

OBJECTIVES: To examine the effectiveness of near-infrared light devices (NIR) on procedure time of successful cannulation, success rate at the first attempt, and pain scores among pediatric patients and explore potential covariates on the intervention effect. BACKGROUND: Pediatric patients have encountered a high failure rate as compared with adult patients using traditional cannulation. NIR devices might help to access veins with an optimum viewing area and eliminate the number of attempts...

OBJECTIVE: Difficult intravenous access (DIVA) patients are known to have disproportionately poorer vascular access outcomes. The impact of education and training on vascular access outcomes in this vulnerable population is unclear. We aim to demonstrate the success of a program (Operation (O) STICK) on improving vascular access outcomes in DIVA patients. METHODS: This was a quasi-experimental pre-post interventional study conducted at a tertiary care emergency department (ED) with 120,000 annual visits and 1100 hospital beds...

According to research, shock, the most common complication of extremely severe burns, is also the leading cause of mortality among patients with such burns. The case fatality rate reaches 83.45% when the total burn area exceeds 90%. The American Heart Association in 2020 recommended the intraosseous route after the peripheral route and prior to the central venous route when venous cannulation is either difficult or delayed. The use and experience with intraosseous infusion (IO) in extremely severe burns are still limited...

There exists a need for new methods to address treatment anxiety in pediatrics-at the same time, deep breathing exercises and virtual natural environments have both been known to have stress-reducing qualities. This article reports the combined effect of these two methods in a pediatric setting. A feasibility study was conducted in a local hospital. The study had a within-subjects design, and it included 21 child patients aged 8 to 12 years old, who used a virtual reality (VR) relaxation application developed for this purpose during an intravenous cannulation procedure related to their treatment...

Treatment anxiety is a serious problem among child patients. A few studies have addressed this issue with virtual reality solutions, with promising results; however, the applications used have generally been designed for entertainment instead of this purpose. This article studies the potential of using deep breathing exercises in a virtual natural environment to address this issue, with a focus on design approach and user experience. It presents the VirNE-Virtual Natural Environments relaxation application, which is based on known stress-reduction methods, and a feasibility study conducted with it in a local hospital...

BACKGROUND: Central venous catheter insertion is an invasive procedure that can cause complications such as infection, embolization due to air or blood clots, pneumothorax, hemothorax, and, rarely, chylothorax due to damage to the thoracic duct. Herein, we report a case of suspected thoracic duct cannulation that occurred during left central venous catheter insertion. Fortunately, the patient was discharged without any adverse events related to thoracic duct cannulation. CASE SUMMARY: A 46-year-old female patient presented at our department to undergo cytoreductive surgery and hyperthermic intraperitoneal chemotherapy...

Perinatal hypoxic-ischaemic encephalopathy (HIE) is the leading cause of irreversible brain damage resulting in serious neurological dysfunction among neonates. We evaluated the feasibility of positron emission tomography (PET) methodology with 15 O-labelled gases without intravenous or tracheal cannulation for assessing temporal changes in cerebral blood flow ( CBF ) and cerebral metabolic rate for oxygen ( CMRO2 ) in a neonatal HIE rat model. Sequential PET scans with spontaneous inhalation of 15 O-gases mixed with isoflurane were performed over 14 days after the hypoxic-ischaemic insult in HIE pups and age-matched controls...

INTRODUCTION: Needle-related distress is common among people receiving hemodialysis and affects quality of life and treatment decisions, yet little evidence exists to guide management. This study explored patients' experiences of needle-related distress to inform the development of prevention, identification, and management strategies. METHODS: Semistructured interviews concerning dialysis cannulation, needle-related distress, and potential solutions were conducted with people with current or recent experience of hemodialysis ( N  = 15) from a tertiary hospital-based service...

BACKGROUND: Preoperative anxiety leads to adverse clinical outcomes and long-term maladaptive behavioural changes. The role of intranasal atomised dexmedetomidine and atomised ketamine as premedication to produce sedation and anxiolysis in paediatric neurosurgical patients has not been extensively studied. OBJECTIVE: To study the efficacy of intranasal atomised dexmedetomidine and intranasal atomised ketamine as premedication in producing sedation and facilitating smooth induction in children undergoing spinal dysraphism surgery...

Peripheral intravenous cannulation (PIVC) is a routine procedure in perioperative, and critical care settings and nearly one-third of the patients may have difficult intravenous access (DIVA). PIVC is challenging in a prone position in an intraoperative setting when there is a need for emergency access. Point of care ultrasonography (POCUS) is becoming the standard for assisting DIVA and improving the success rate. The small saphenous vein (SSV) in the posterolateral side of the mid-calf is a consistent vein in the lower extremity that provides an acceptable diameter and optimal depth for POCUS-guided PIVC in the prone position...

Polymeric prodrugs have been applied to control the delivery of various types of therapeutics. Similarly, conjugation of peptide therapeutics to lipids has been used to prolong systemic exposure. Here, we extend on these two approaches by conjugating brush polyethylene glycol (PEG) polymers with different lipid components including short-chain (1C2) or medium-chain (1C12) monoalkyl hydrocarbon tails, cholesterol (Cho), and diacylglycerols composed of two medium-chain (2C12) or long-chain (2C18) fatty acids...
