Efficacy of an Infrared Visualization Technique for the Identification of the Peripheral Venous Access Site in Patients With Cystic Fibrosis Aged 12 Years and Older

Overview

Cystic fibrosis is a rare chronic genetic disease that mainly affects the respiratory tract and the digestive system. Their management includes multi-year intravenous antibiotic treatments and repeated venous sampling. The venous access is a source of difficulties that nurses who take care of these patients face on a daily basis. In addition, multiple attempts at punctures can induce anxiety and pain in patients. It is therefore important to limit failures. Vein visualization technologies exist: guidance echo, portable trans lumination or infrared visualization can guide venipuncture and limit failures. Compared with the guided echo or the portable trans lumination, the infrared visualization is easy to use and does not pose a risk for the patient. Nevertheless, studies evaluating this technique are few in chronic diseases and mainly conducted in young children. This study aims to show that the use of a vein illumination system (VIS) should improve the peripheral venous access at the first attempt (thus limiting venous lesions) in adolescent and adult patients with cystic fibrosis, and improve comfort of the patient (pain, apprehension of the gesture).

Background : Cystic fibrosis is a rare chronic genetic disease that mainly affects the respiratory tract and the digestive system. Their management includes multi-year intravenous antibiotic treatments and repeated venous sampling. The venous access is a source of difficulties that nurses who take care of these patients face on a daily basis. In addition, multiple attempts at punctures can induce anxiety and pain in patients. It is therefore important to limit failures. Vein visualization technologies exist: guidance echo, portable trans lumination or infrared visualization can guide venipuncture and limit failures. Compared with the guided echo or the portable trans lumination, the infrared visualization is easy to use and does not pose a risk for the patient. Nevertheless, studies evaluating this technique are few in chronic diseases and mainly conducted in young children. This study aims to show that the use of a vein illumination system (VIS) should improve the peripheral venous access at the first attempt (thus limiting venous lesions) in adolescent and adult patients with cystic fibrosis, and improve comfort of the patient (pain, apprehension of the gesture). Objectives of the study : The main objective of the study is to demonstrate that the use of a vein illumination system (VIS) for the placement of a peripheral venous line or venous sampling on the hand, forearm or fold of the elbow improves peripheral venous access (PVA) successful on the first attempt. The secondary objectives are : * To study the efficacy of VIS for peripheral venous access (placement of a peripheral venous line or peripheral venous sampling in the hand, forearm or elbow) on the number of attempts. * To study the impact of the use of SIV on the patient's pain felt during the peripheral venous access procedure. * To study the impact of VIS on patient anxiety prior to peripheral venous access. * To describe the nurses and nursing students satisfaction with the use of the VIS device for peripheral venous access. * To study the determinants of the success of peripheral venous access at the first attempt among the characteristics of nurses and nursing students (age, year of obtaining their diploma, experience within the cystic fibrosis ressource and competence center). * To describe the nurses and nursing students satisfaction with the use of A-DIVA scale. Study design The study will last 36 months. It is an open and randomized multicenter cluster study, with sequential allocation of the device (stepped wedge allocation), comparing a group of patients benefiting from a technique of locating the puncture site by a venous illumination system for a peripheral venoux access (hand, forearm, fold of the elbow) to a group of patients whose veins are identified according to the usual modality of a peripheral venoux access. The cluster is defined by the Cystic Fibrosis Resource and Competence Center (CRCM). Expected results For the patients, the use of a venous illumination system device during the peripheral venous access should facilitate the success of the gesture on the first attempt, allowing to : * Reduce their pain due to multiple attempts. * Reduce their anxiety associated with peripheral venous access. * Preserve their venous capital This could have an impact on their care, such as making it easier to consult for them and being less anxious about peripheral venous access. For the nurses, using a venous illimunation system device could * Reduce their apprehension of peripheral venous access gesture * Save their time with fewer peripheral venous access are repeated. It is considered that this technique will be distributed to all Cytic Fibrosis Ressource and Competence Centers (CRCM) in order to improving the comfort of the chronically ill patient with repeated blood tests and intravenous treatments.
