A rare case of sepsis due to Corynebacterium macginleyi from central venous catheter in an elderly woman

2011

Corynebacterium macginleyi is a gram positive rod that causes especially ocular infections: since now only six elderly cases of extraocular infection are described. A 76 years old bedridden woman with a central venous catheter was hospitalized for 10 days of persistent fever. She was treated before with vancomicin and then with imipenem. The clinical conditions improved and the patient was discharged after two weeks of hospitalization. Among recognised risk factors for this infection the advanced age, indwelling devices and immunosuppression seem the most important. On the other hand, the antibiotics of choice are glycopeptides while the association of another antibiotic is recommended in o…

Umbilical venous catheters placement evaluation on frontal radiogram: application of a simplified flow-chart for radiology residents

2017

Background: Umbilical Venous Catheter (UVC) are commonly used in neonatal period; they can be not correctly positioned and could be associated with complications. The purpose of this article is to suggest a flow-chart to evaluate the placement of UVC, testing it in young radiologists-in-training. Method: We developed a simple flow-chart to asses, steps by step, UVC placement considering its course and tip location (ideally placed in the atriocaval junction). We tested the flow-chart impact asking to 20 residents to evaluate the placement of 10 UVC before and after they familiarized with the flow-chart and the anatomical findings of a newborn. The agreement among the 20 students was evaluate…

A quality improvement study on the reduction of central venous catheter-associated bloodstream infections by use of self-disinfecting venous access c…

2020

Background Contamination of the catheter hub is an important source of central line-associated bloodstream infections (CLABSI); catheter hub caps incorporating a 70% isopropyl alcohol aim are designed to reduce contamination and hence CLABSI rates. Supporting data in high-risk hematological and oncological patients on the clinical effectiveness of this approach are sparse. Methods We conducted a before-after single center study accompanying the introduction of such caps at our department. Retrospective data from the year prior to the introduction were compared to 1 year of prospective data. Results The control and antiseptic barrier cap (ABC) groups consisted of 309 and 289 patients present…

Comparison of central venous catheterization with and without ultrasound guide

2003

Purpose: To compare the effectiveness, safety and time needed to perform central venous catheterization (CVC) in the presence or absence of an ultrasound (US) guide. Methods: Between January 1999 and February 2002 we performed CVCs in 196 patients: 105 patients received US guided CVC (group I) and 91 patients had CVC without US guide (group II). Results: The average time to perform CVC was shorter with US guide (4 vs 7min). The utilization of the US guide was also associated with improved success (98.09% vs 91.2%, p < 0.025) and lack of major complications (0% vs 9.8%, p < 0.001). Conclusions: US-guided CVC affords an easier, safer and more rapid cannulation of a central vein. It is especia…

Vantaggi degli ultrasuoni nel posizionamento di un agocannula nella vena giugulare interna (nuove note di tecnica)

2004

The authors analized the result of 175 central venous ca he- terization CVC. of internal jugular vein performed with the ultrasound guide (US) from January 1998 to October 2002. The average performing time was 45 minutes. 98.2% of success and 4% of complications (one pagal hypotension, one artery puncture, four catheter dislocation, one haeiuatoinai). The US guide CVC is a safe procedure with short performing time, low rate of failures and complications and high rate of success: it is helpful in all patients with vascular anatomical variations, with not visualized or Land marks and with coagulation disorders.

One shoot seldinger central venous catheterization in dialyzed patients

2015

Introduction: Central Venous Catheterization is necessary in uremic patient (before dialysis) and many other conditions. In this study we demonstrated the advantages of ultrasonography to perform the procedure. Materials and methods: 48 uremic patient were submitted to ultrasound-guided central venous catheterization. The procedure was performed following the Seldinger “one shot” technique. Results: The mean operative time was 4 minutes, with a high rate of success (100%) and a low percentage of complications (2%). Conclusion: The ultrasound-guided central venous catheterization is a safe procedure, rapid and easy to perform. The procedure has a low rate of failures and complications and a …

Post-ERCP pancreatitis: A single center experience and an update on prevention strategies

2015

Pancreatitis is the most frequent complication of the ERCP; in unselected patients the incidence is 3.5%, reaching 25%, and is mild-moderate in 90%. A stratification of patients into low or high risk is important to provide adequate information to patients and to decide when refer them to tertiary centers; moreover, many prophylactic measures have been proposed over years. Our aim was to select risk factors for PEP and compare them with current literature in order to propose adequate preventive strategies.It was analyzed the occurrence of Post-ERCP Pancreatitis in a series of 492 consecutives patients treated with ERCP by two expert interventional endoscopists. The possible risk factors wer…

Quantitative Coronary Angiography and Digital Densitometric Perfusion Measurements?How to Assess the Success of Intracoronary Balloon Dilatation

1988

Densitometric evaluation of digital subtraction angiocardiograms allows the assessment of local myocardial perfusion before and after pharmacological stimulation of coronary flow reserve during the catheterization procedure. This report deals with a case of a severe stenosis of the left coronary artery in which PTCA was regarded successful based on an appropriate increase in luminal diameter while an intima and media dissection at the dilatation site was documented. The perfusion measurements, however, pointed out a clear impairment of poststenotic myocardial perfusion after PTCA.

Simple technique for the intraoperative detection of Crohn's strictures with a calibration sphere.

2000

Several methods have been used to detect and evaluate small-bowel strictures in Crohn's disease. We describe a simple technique for the calibration of strictures using a 2.5-cm medical plastic sphere. This method provides an aseptic, safe, and effective calibration of the entire small bowel.
