Venous access devices for the delivery of long-term chemotherapy: the CAVA three-arm RCT.

Background: Venous access devices are used for patients receiving long-term chemotherapy. These include centrally inserted tunnelled catheters or Hickman-type devices (Hickman), peripherally inserted central catheters (PICCs) and centrally inserted totally implantable venous access devices (PORTs).

Objectives: To evaluate the clinical effectiveness, safety, cost-effectiveness and acceptability of these devices for the central delivery of chemotherapy.

Central venous access devices for the delivery of systemic anticancer therapy (CAVA): a randomised controlled trial.

Background: Hickman-type tunnelled catheters (Hickman), peripherally inserted central catheters (PICCs), and totally implanted ports (PORTs) are used to deliver systemic anticancer treatment (SACT) via a central vein. We aimed to compare complication rates and costs of the three devices to establish acceptability, clinical effectiveness, and cost-effectiveness of the devices for patients receiving SACT.

Methods: We did an open-label, multicentre, randomised controlled trial (Cancer and Venous Access [CAVA]) of three central venous access devices: PICCs versus Hickman (non-inferiority; 10% margin); PORTs versus Hickman (superiority; 15% margin); and PORTs versus PICCs (superiority; 15% margin).

Retained port connectors after central venous port removal.

We report three cases where the connector/sleeve, which helps fix the flexible catheter section to a port injection chamber, was inadvertently left in scar tissue during port removal. Concerned patients presented months later with a palpable subcutaneous nodule, near the port site. The nodules were variably imaged with plain X-rays, mammography or ultrasound with the diagnosis correctly made by a surgeon familiar with devices.

A narrative review of long-term central venous access devices for the intensivist.

Long-term central venous access devices are increasingly prevalent and consequently often encountered by intensivists. This review introduces the different types of long-term central venous access devices, outlines their potential utility, examines potential complications associated with their use and outlines an approach to the management of these complications.

pRotective vEntilation with veno-venouS lung assisT in respiratory failure: A protocol for a multicentre randomised controlled trial of extracorporeal carbon dioxide removal in patients with acute hypoxaemic respiratory failure.

One of the few interventions to demonstrate improved outcomes for acute hypoxaemic respiratory failure is reducing tidal volumes when using mechanical ventilation, often termed lung protective ventilation. Veno-venous extracorporeal carbon dioxide removal (vv-ECCOR) can facilitate reducing tidal volumes. pRotective vEntilation with veno-venouS lung assisT (REST) is a randomised, allocation concealed, controlled, open, multicentre pragmatic trial to determine the clinical and cost-effectiveness of lower tidal volume mechanical ventilation facilitated by vv-ECCOR in patients with acute hypoxaemic respiratory failure.

A multicentre snapshot study of the incidence of serious procedural complications secondary to central venous catheterisation.

Despite the high number of central venous access devices inserted annually, there are limited data on the incidence of the associated procedural complications, many of which carry substantial clinical risk. This point was highlighted in the recently published Association of Anaesthetists of Great Britain and Ireland 'Safe vascular access 2016' guidelines. This trainee-led snapshot study aimed to identify the number of central venous catheter insertions and the incidence of serious complications across multiple hospital sites within a fixed two-week period.

Outcomes following out-of-hospital cardiac arrest: What is the potential for donation after circulatory death?

We conducted a prospective observational study on 100 consecutive patients admitted to intensive care units at Leeds General Infirmary following out-of-hospital cardiac arrest. In the non-survivors, we reviewed their potential for organ donation via donation after circulatory death. Out of the 100 patients, 53 did not survive to hospital discharge.

Development of the UK Vessel Health and Preservation (VHP) framework: a multi-organisational collaborative.

Vascular access is an important part of many patient care management plans but has some unwanted risks. Previous work published by Moureau et al. (2012) inspired a working group led by the UK Infection Prevention Society (IPS) to produce a vessel health and preservation (VHP) framework.

Arterial vessels behind the right internal jugular vein with relevance to central venous catheterisation.

During right internal jugular vein cannulation, complications can arise due to transfixion of the posterior wall and damage to other vessels. The risks to the subclavian artery and its branches are less well appreciated than the carotid artery. Example images are lacking in the literature.

Misplaced central venous catheters: applied anatomy and practical management.

Large numbers of central venous catheters (CVCs) are placed each year and misplacement occurs frequently. This review outlines the normal and abnormal anatomy of the central veins in relation to the placement of CVCs. An understanding of normal and variant anatomy enables identification of congenital and acquired abnormalities.

Ultrasound-guided infraclavicular axillary vein cannulation: a useful alternative to the internal jugular vein.

Background: Ultrasound (US) guidance reduces complications and increases accuracy during internal jugular vein (IJV) cannulation. The subclavian vein (SCV) is popular but is less amenable to US guidance. The axillary vein (AxV), a direct continuation of the SCV, is an alternative, but to date, experience with US is limited to small case series.

Nitrous oxide exposure does not seem to be associated with increased mortality, stroke, and myocardial infarction: a non-randomized subgroup analysis of the General Anaesthesia compared with Local Anaesthesia for carotid surgery (GALA) trial.

Background: Nitrous oxide has been associated with increased vascular risk in the perioperative period. Here, we conducted a secondary analysis of the GALA trial to ascertain the impact of nitrous oxide on outcomes after carotid surgery under general anaesthesia (GA).

Methods: One thousand seven hundred and seventy-three patients underwent GA, but 158 patients were excluded from this analysis as nitrous oxide use was unknown.

Quality and outcomes in anaesthesia: lessons from litigation.

Healthcare litigation in the UK continues to grow at an alarming rate, with claims against anaesthetists and critical care physicians increasing each year. This has led to a huge financial burden for the taxpayer and a sharp increase in professional indemnity fees for individual doctors. Although such litigation should provide valuable information to educate practitioners and reduce future similar claims, there appear to be significant barriers preventing important lessons from being learned.

Early cuff anchorage for tunneled central venous catheters using a buried absorbable suture.

Purpose: Long-term tunneled cuffed central venous catheters (CVC) are widely used for the administration of chemotherapy, parenteral nutrition, and fluids. External migration and displacement of catheters have been reported to occur in 2.4% to 24% of cases, prompting the development of various anchoring strategies.
