Abstract

Critically ill patients in an intensive care setting often require arterial catheters for blood pressure monitoring and arterial blood collection. Arterial catheter failure, which manifests in both mechanical and infective forms, remains common. Dressing and securement inadequacies may impact this failure; however, the best method for dressing and securing arterial catheters is yet to be determined. The objective of this study was to establish the feasibility of a definitive randomised controlled trial comparing methods for dressing and securing arterial catheters and to prevent device failure in an adult intensive care setting. A pilot, parallel-group, randomised controlled trial was conducted between April 2017 and June 2018. Patients receiving treatment in two adult intensive care units (Queensland, Australia) were eligible for inclusion and were allocated to receive either (i) an integrated securement dressing or (ii) a simple polyurethane dressing (with gauze/foam), applied to their newly inserted arterial catheters. Primary outcomes were (i) feasibility (defined by pre-established criteria: patient eligibility, consent, protocol adherence, retention, and staff acceptability) and (ii) all-cause arterial catheter failure (a...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
