BACKGROUND: Epinephrine administered by low umbilical venous catheter (UVC) or endotracheal tube (ETT) is indicated in neonates who fail to respond to positive pressure ventilation and chest compressions at birth. Pharmacokinetics of ETT epinephrine via fluid-filled lungs or UVC epinephrine in the presence of fetal shunts is unknown. We hypothesized that epinephrine administered by ETT or low UVC results in plasma epinephrine concentrations and rates of return of spontaneous circulation (ROSC) similar to right atrial (RA) epinephrine...

Biofilm forming capacity of yeasts colonizing the intravenous devices is considered a key factor involved in the pathogenesis of Candida catheter-related bloodstream infections (CCRBSI). The biofilm production of strains of Candida spp. isolated both from the CVC and from the blood of patients with CCRBSI was compared to that of strains isolated from patients not having CCRBSI. Results, expressed in terms of Biofilm Index (BI), revealed that biofilm-producing strains were isolated in the CCRBSI group with a frequency significantly higher than in the non-CCRBSI group (χ(2) = 4...

Pulmonary embolism (PE) is a major cause of both acute and long-term morbidity for a large number of patients worldwide, and massive PE is frequently fatal. Right ventricular (RV) dysfunction is a key determinant of prognosis in the acute phase of PE. Patients with clinically overt RV failure, that is, with cardiogenic shock or persistent hypotension at presentation (acute high-risk PE), are clearly in need of immediate reperfusion treatment with systemic thrombolysis or, alternatively, surgical or catheter-directed techniques...

A 55-year-old woman was referred for radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Twelve-lead ECG was normal during sinus rhythm. The electrophysiological study showed an AH interval of 114 ms and HV interval of 42 ms during sinus rhythm. This article is protected by copyright. All rights reserved.

PURPOSE: Continuous intraoperative epidural analgesia may improve post-operative pain control and decrease opioid requirements. We investigate the effect of epidural infusion initiation before or after arrival in the post-anesthesia care unit on recovery room duration and post-operative opioid use. METHODS: We performed a retrospective chart review of abdominal, thoracic and orthopedic surgeries where an epidural catheter was placed prior to surgery at the University of Washington Medical Center during a 24 month period...

Background: Arginine is considered to be an essential amino acid in various (patho)physiologic conditions of high demand. However, dietary arginine supplementation suffers from various drawbacks, including extensive first-pass extraction. Citrulline supplementation may be a better alternative than arginine, because its only fate in vivo is conversion into arginine.Objective: The goal of the present research was to determine the relative efficiency of arginine and citrulline supplementation to improve arginine availability...

AIMS AND OBJECTIVES: To estimate the prevalence of difficult venous access in complex patients with multimorbidity and to identify associated risk factors. BACKGROUND: In highly complex patients, factors like ageing, the need for frequent use of irritant medication and multiple venous catheterisations to complete treatment could contribute to exhaustion of venous access. DESIGN: A cross-sectional study was conducted. METHODS: "Highly complex" patients (n = 135) were recruited from March 2013-November 2013...

PURPOSE: Our objective was to investigate whether training on phantoms with smaller or larger vessels would improve success rate in novice medical students learning this skill. METHODS: Medical students who participated in a voluntary, extracurricular ultrasound training day were asked to participate in the study as part of their procedural training.

BACKGROUND AND OBJECTIVES: Hemodynamically unstable idiopathic ventricular tachycardias (VTs) are a challenge for activation or entrainment mapping technique. Mechanical circulatory support is an option, but is not always readily available. In this study, we investigated the safety and efficacy of hemodynamic support using intravenous (IV) dopamine solely during radiofrequency catheter ablation (RFCA) of hemodynamically unstable VT. SUBJECTS AND METHODS: Seven out of 86 patients with hemodynamically unstable idiopathic VT underwent de novo RFCA using dopamine in our single center...

Compare individualized contrast protocol, or weight-based protocol, to standard methodology in evaluating acute pulmonary embolism.Retrospective chart review was performed on patients undergoing computed tomography angiography with standard contrast protocol (n = 50) or individualized protocol (n = 50). Computerized tomography images were assessed for vascular enhancement and image quality.Demographics were comparable, however, more patients in the individualized group were admitted to intensive care unit (48% vs 16%, P = 0...

Patients receiving intravenous therapy require reliable venous access. Typically patients with poor peripheral access or requiring long-term treatment from an outpatient antibiotic therapy (OPAT) service need to receive secondary care input for safe central line placement, and radiological confirmation of the correct line tip placement where necessary, if treatment is to proceed as planned. Technological developments that enable accurate ultrasound-guided vein selection and electrocardiograph (ECG)-guided central line tip placement have eliminated the need for radiological or fluoroscopic confirmation of correct tip placement for peripherally placed central catheters (PICCs)...

The metabolic response of dairy cows undergoing an extended lactation to an insulin tolerance test (ITT) was investigated. Twelve multiparous Holstein-Friesian cows that calved in late winter in a pasture-based system were managed for a 670-d lactation by delaying rebreeding. Four 5-wk experimental periods commenced at approximately 73, 217, 422, and 520 d in milk (DIM). Cows were offered a diet of perennial ryegrass (73 and 422 DIM) or pasture hay and silage (217 and 520 DIM) supplemented with 1 kg dry matter (DM) of grain (control; CON) or 6 kg DM of grain (GRN)...

Gram-positive infections are currently a therapeutic challenge because of the emergence of strains resistant to first-line antibiotics. Consequently, in the last few years, new antibiotics have been developed with activity against multiresistant Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and strains with intermediate sensitivity to vancomycin. Among the new antibiotics approved for the treatment of these microorganisms, dalbavancin is a semisynthetic lipoglycopeptide derived from teicoplanin, but has a superior efficacy profile to the latter...

A short peripheral intravenous catheter or cannula (PIVC) is frequently used to deliver chemotherapy in oncology practice. Although safe and easy to insert, PIVCs do fail, leading to personal discomfort for patients and adding substantially to treatment costs. As the procedure of peripheral catheterization is invasive, there is a need for greater consistency in the choice, insertion and management of short PIVCs, particularly in the oncology setting where there is a growing trend for patients to receive many different courses of IV treatment over a number of years, sometimes with only short remissions...

RATIONALE: Oxycodone is one of the most widely prescribed painkillers in the USA. However, its use is complicated by high abuse potential. As sex differences have been described in drug addiction, the present study tested for sex differences in intravenous oxycodone self-administration in rats. METHODS: Male and female Sprague-Dawley rats were implanted with jugular vein catheters and trained to self-administer oxycodone (0.03 mg/kg/infusion) under fixed ratio 1 (FR1), FR2, and FR5 schedules of reinforcement followed by a dose-response study to assess sensitivity to the reinforcing effects of oxycodone...

PURPOSE: Competency-based medical education has been successfully instituted in graduate medical education through the development of Milestones. Consequently, the Association of American Medical Colleges implemented the core entrustable professional activities initiative to complement this framework in undergraduate medical education.
