On-demand use of peripheral arterial catheters outside the Intensive Care Unit: Development and retrospective evaluation of an internal protocol for insertion and management

Adverse events with arterial catheters in intensive care units: a scoping review

INTRODUCTION

The installation of an arterial line is one of the invasive procedures performed for hemodynamic monitoring and, even with its clear importance in intensive care, it is still an invasive procedure and liable to cause harms to the patients.

OBJECTIVE

To identify the adverse events associated with the use of arterial catheters in critically-ill patients in the world scientific production.

METHODOLOGY

The present scoping review was conducted according to the JBI methodology for scoping reviews. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist was used for reporting. The research question was "Which adverse events related to the use of arterial catheters in patients admitted to intensive care are more evident in the literature?". Data collection took place in the following databases: LILACS; MEDLINE; EMBASE; CINAHL, EBSCOhost; and WEB OF SCIENCE.

RESULTS

Through the search strategies, 491 articles were found in the databases. After exclusion of duplicates, peer analysis of titles and abstracts, full reading and screening of lists of references, the final sample of studies included was 38 articles. The main harms cited by the publications were as follows: limb ischemia, thrombosis, hemorrhage, accidental removal, inadvertent connection of inadequate infusion solution, pseudoaneurysm and bloodstream infection.

CONCLUSIONS

It was evidenced that patients are subjected to risks of adverse events from the insertion moment to removal of the arterial catheter, focusing on the infusion solution used to fill the circuit, the type of securement and dressings chosen, as well as the Nursing care measures for the prevention of bloodstream infection.

Severe ischemia after radial artery catheterization: A literature review of published cases

INTRODUCTION

Severe ischemia is a rare complication of radial artery catheterization (RAC). This study aims to summarize risk factors of RAC-elicited severe hand ischemia, preventive, and therapeutic management.

METHODS

Literature search was conducted in eight electronic English and Chinese databases to identify relevant published cases. Data of interest was extracted and analyzed.

RESULTS

Database search identified 28 articles reporting cases of 57 patients developing hand ischemia following RAC. Patients aged between 1 day and 88 years. The indications for RAC included surgery, shock, cardiac arrest, and Neonatal Intensive Care Unit (NICU) admission. Identified risk factors included pre-existing vascular diseases, hypotension, arterial anatomical abnormality or small diameter, vasoconstrictors, and catheter-related problems. Totally, 18 patients complained pain; 32 developed discoloration; 19 pulselessness; 3 paresthesia; 13 swolleness and 19 coldness. Eventually, 30 patients recovered well, but 20 patients unfortunately underwent digital amputation and three patients deceased due to non-RAC-related causes.

CONCLUSION

Severe hand ischemia following RAC is a rare complication, with the reported incidence of approximately 0.09%. There is no definite predictor for RAC-related hand ischemia, but patients with risk factors are prone to the occurrence of hand ischemia. It's vital to initiate early recognition and proactive strategies for a best practice RAC insertion.

10 best practice tips with radial arterial catheterization

Radial arterial catheters (RAC) are used extensively across critical care settings (Anesthesia, Intensive Care, Emergency Medicine) for continuous hemodynamic monitoring, allowing for immediate adjustments in vasopressor therapies and blood collection. Radial catheter failures are an ongoing significant issue for critical care clinicians with reported incidences at almost 25%. Common complications include loss of function, lack of blood return, poor quality waveforms and dislodgement, posing potential patient risks, and sudden loss of intra-arterial monitoring frequently requires prompt replacement. Contemporary research and technological improvements have highlighted several concepts to enhance the approach of RAC insertion and management while reducing immediate and late complications. The authors have prioritized the following 10 "best practice" aspects that may improve overall device function and reliability.
