Expert consensus-based clinical practice guidelines management of intravascular catheters in the intensive care unit.

The French Society of Intensive Care Medicine (SRLF), jointly with the French-Speaking Group of Paediatric Emergency Rooms and Intensive Care Units (GFRUP) and the French-Speaking Association of Paediatric Surgical Intensivists (ADARPEF), worked out guidelines for the management of central venous catheters (CVC), arterial catheters and dialysis catheters in intensive care unit. For adult patients: Using GRADE methodology, 36 recommendations for an improved catheter management were produced by the 22 experts. Recommendations regarding catheter-related infections' prevention included the preferential use of subclavian central vein (GRADE 1), a one-step skin disinfection(GRADE 1) using 2% chlorhexidine (CHG)-alcohol (GRADE 1), and the implementation of a quality of care improvement program. Antiseptic- or antibiotic-impregnated CVC should likely not be used (GRADE 2, for children and adults). Catheter dressings should likely not be changed before the 7th day, except when the dressing gets detached, soiled or impregnated with blood (GRADE 2- adults). CHG dressings should likely be used (GRADE 2+). For adults and children, ultrasound guidance should be used to reduce mechanical complications in case of internal jugular access (GRADE 1), subclavian access (Grade 2) and femoral venous, arterial radial and femoral access (Expert opinion). For children, an ultrasound-guided supraclavicular approach of the brachiocephalic vein was recommended to reduce the number of attempts for cannulation and mechanical complications. Based on scarce publications on diagnostic and therapeutic strategies and on their experience (expert opinion), the panel proposed definitions, and therapeutic strategies.

[Central venous access for cancer chemotherapy]. / Quel accès veineux central pour la chimiothérapie ?

The tip of a long term central venous access should be located at the junction of the superior vena cava with the right atrium in order to reduce the incidence of dysfunction and venous thromboses. Picc-lines have their place for treatments of less than 6 months with obvious advantages in terms of discretion and comfort. Long-term sequential chemotherapy is an indisputable indication of an implantable port, while long-term parenteral nutrition is an indication of a tunneled cuffed catheter. In case of mediastinal compression, the risk-benefit ratio favors femoral access. Catheter related venous thrombosis or infection do not necessarily require the withdrawal of the device. A device that is no longer used should be removed when the likelihood of recurrence of the disease is low or too far.

Peroperative electrocardiographic control of catheter tip position during implantation of femoral venous ports.

PURPOSE: Electrocardiographic (ECG) guidance has been shown to be as effective than fluoroscopy to position the tip of central venous devices close to the superior vena cava (SVC)-right atrium (RA) junction. When SVC access is contraindicated, a femoral access may be used. The aim of this prospective study is to evaluate the effectiveness of ECG guidance to position the tip of femoral ports at inferior vena cava (IVC)-RA junction. METHODS: Inclusion criterion was the need for femoral port implantation. After insertion of the dilator in the femoral vein, the catheter with the guide wire inside was introduced and the ECG signal collected at the tip of the guide (Celsite™ ECG, B. Braun, Germany) or via saline injected in the catheter (Nautilus™, Perouse, France). Fluoroscopy was performed at each change of the P-wave from IVC to RA. A final X-ray was performed after withdrawing the catheter 2 cm below the first P-wave change. RESULTS: A total of 18 patients were included between December 2011 and June 2013. The P-wave was most often negative in IVC, biphasic when the catheter entered RA and giant and positive at the top of RA. When the catheter was withdraw 2 cm below the first biphasic P-wave the tip was just below the IVC-RA junction in 17 patients. In one patient P-wave changes were not significant and the final position was adjusted under fluoroscopy. CONCLUSIONS: ECG guidance is effective to assess catheter tip position during femoral port placement and avoids the need for radiological methods.

Guidelines on the use of ultrasound guidance for vascular access.

Insertion of vascular access is a common procedure with potential for iatrogenic events, some of which can be serious. The spread of ultrasound scanners in operating rooms, intensive care units and emergency departments has made ultrasound-guided catheterisation possible. The first guidelines were published a decade ago but are not always followed in France. The French Society of Anaesthesia and Intensive Care has decided to adopt a position on this issue through its Guidelines Committee in order to propose a limited number of simple guidelines. The method used was the GRADE(®) method using the most recently published meta-analyses as the source of references. The level of evidence found ranged from low to high and all the positive aspects associated with ultrasound guidance, i.e. fewer traumatic complications at puncture, probably or definitely outweigh the potential adverse consequences regardless of whether an adult or child is involved and regardless of the site of insertion.

International evidence-based recommendations on ultrasound-guided vascular access.

PURPOSE: To provide clinicians with an evidence-based overview of all topics related to ultrasound vascular access. METHODS: An international evidence-based consensus provided definitions and recommendations. Medical literature on ultrasound vascular access was reviewed from January 1985 to October 2010. The GRADE and the GRADE-RAND methods were utilised to develop recommendations. RESULTS: The recommendations following the conference suggest the advantage of 2D vascular screening prior to cannulation and that real-time ultrasound needle guidance with an in-plane/long-axis technique optimises the probability of needle placement. Ultrasound guidance can be used not only for central venous cannulation but also in peripheral and arterial cannulation. Ultrasound can be used in order to check for immediate and life-threatening complications as well as the catheter's tip position. Educational courses and training are required to achieve competence and minimal skills when cannulation is performed with ultrasound guidance. A recommendation to create an ultrasound curriculum on vascular access is proposed. This technique allows the reduction of infectious and mechanical complications. CONCLUSIONS: These definitions and recommendations based on a critical evidence review and expert consensus are proposed to assist clinicians in ultrasound-guided vascular access and as a reference for future clinical research.

Wound healing delay after central venous access following DCF/VEGF-trap therapy.

Hypertension, proteinuria, thromboembolic or bleeding events are well-recognized complications occurring while targeting VEGF pathway. Wound healing dysfunctions have also been described in patients undergoing major surgery. For the first time, we report wound healing delay after central venous access following DCF-VEGF-Trap. VEGF-Trap may affect both angiogenesis and reepithelialization which are necessary to the normal repair process.

[Complications of central venous and indwelling catheterization]. / Complications des dispositifs intraveineux de longue durée.

Complications on Hickman central venous catheter and venous access ports Hickman central venous catheter and venous access ports are widely used in patients with hematology or oncology disorders. However, these long-term venous access devices can be the source of several kinds of complications that may compromise the functional and/or vital patient's prognosis. All these complications must be known, diagnosed, treated and prevented. If there is no consensus concerning the prevention of catheter-related thrombosis, various methods are now available to diagnose, treat and prevent device-related bloodstream infections. Extravasation of corrosive drugs represents a very serious complication of long-term venous access devices. The surgical technique that uses early subcutaneous wash-out in acute extravasation injuries is simple and safe; it helps to reduce the severe sequelae of highly toxic drug extravasation for the patient.

[Treatment of venous thrombosis in cancer patients: practical aspects]. / Aspects pratiques de la prise en charge des thromboses chez le patient cancéreux.

The risk of venous thromboembolism (VTE) is increased in association with malignancy, and has a potential to produce significant morbidity and mortality. Treatment of such patients with anticoagulants is associated with both benefit and a high rate of complications. In the early phase, the treatment is usually achieved with low molecular weight heparin (LMWH), which has a number of advantages over unfractionated heparin (UFH): once or twice daily administration, no necessary laboratory monitoring, lesser risk of bleeding and no drugs interactions. Nevertheless, the UFH is the anticoagulant of choice when a rapid anticoagulant effect or stop of anticoagulant effect is required, in the treatment of massive pulmonary embolism or severe renal insufficiency. Prolonged anticoagulation with LMWH (over 3 or 6 months) appears to be beneficial on survival for such patients. The subject of anticoagulation in patients with primary or secondary brain tumours is controversial. The long-term anticoagulation mainly use LMWH or vitamin K antagonist. The last ones are more difficult to use because of an unpredictable response with higher rate of recurrence and bleeding. The optimal duration of treatment is not known but the patients should be treated for at least 6 months, even at least 12 months after a second episode of venous thromboembolism. On the primary prevention in high-risk surgical oncology, the LMWH are at least as effective and safer as UFH when the optimal dose was administered. For the medical patients, the use of prophylactic anticoagulant treatment is less clear except the patients who are bedridden for prolonged periods of time. For the secondary prevention, the LMWH seems to be more effective over vitamin K antagonists. For these patients, the anticoagulant therapy is recommended indefinitely or until cancer is resolved.

Potential exposure to hepatitis C virus through accidental blood contact in interventional radiology.

PURPOSE: To quantify the prevalence of accidental blood exposure (ABE) among interventional radiologists and contrast that with the prevalence of patients with hepatitis C virus (HCV) undergoing interventional radiology procedures. MATERIALS AND METHODS: A multicenter epidemiologic study was conducted in radiology wards in France. The risk of ABE to radiologists was assessed based on personal interviews that determined the frequency and type of ABE and the use of standard protective barriers. Patients who underwent invasive procedures underwent prospective sampling for HCV serologic analysis. HCV viremia was measured in patients who tested positive for HCV. RESULTS: Of the 77 radiologists who participated in 11 interventional radiology wards, 44% reported at least one incident of mucous membrane blood exposure and 52% reported at least one percutaneous injury since the beginning of their occupational activity. Compliance with standard precautions was poor, especially for the use of protective clothes and safety material. Overall, 91 of 944 treated patients (9.7%) tested positive for HCV during the study period, of whom 90.1% had positive viremia results, demonstrating a high potential for contamination through blood contacts. CONCLUSIONS: The probability of HCV transmission from contact with contaminated blood after percutaneous injury ranged from 0.013 to 0.030; the high frequency of accidental blood exposure and high percentage of patients with HCV could generate a risk of exposure to HCV for radiologists who perform invasive procedures with frequent blood contact. The need to reinforce compliance with standard hygiene precautions is becoming crucial for medical and technical personnel working in these wards.

Experience at a single institution with endovascular treatment of mechanical complications caused by implanted central venous access devices in pediatric and adult patients.

OBJECTIVE: Our objective was to describe the technical aspects and evaluate the feasibility, safety, and efficacy of endovascular management of mechanical complications related to implanted central venous devices. MATERIALS AND METHODS: One hundred fifty-six patients with cancer, who ranged in age from 3 months to 75 years (mean +/- SD, 47 +/- 18 years), were referred 290 +/- 200 days (mean +/- SD; range, 0-1202 days) after central venous device placement for retrieval of a fractured and embolized central venous device catheter (n = 100), retrieval of a guidewire embolized during placement of a central venous device (n = 2), repositioning of the migrated tip of a central venous device catheter (n = 38), and fibrin-sheath stripping (n = 16). All procedures were performed with the patient under local anesthesia on an outpatient basis, except for the eight pediatric patients. RESULTS: Ninety-five of the 100 embolized catheters and both of the guidewires were successfully retrieved. Retrieval was preceded by repositioning the embolized catheter with a pigtail catheter in 48 of these cases. Most of the procedures were performed with standard vascular tools (loop snares and pigtail catheters); the use of more sophisticated devices (grasping forceps, baskets, or balloons) rarely overcame the failure of a loop snare. Repositioning a migrated catheter tip was achieved with a pigtail catheter in 32 of 38 attempts. Of the repositioned catheters, only 24 could be used. Most of the 11 repositioning and retrieval failures were encountered because the catheter lacked a free end. Fibrin-sheath stripping was always technically successful: all these catheters were patent at 3-month follow-up. No procedure-related complications occurred. CONCLUSION: The endovascular approach is highly feasible, safe, and effective for the management of mechanical complications of central venous devices. It is probably advisable to reserve endovascular repositioning for port catheters that are cumbersome to exchange and to replace simple catheters.
