Brief summary
Compare two methods of managing the lack of CVC blood return : opacification using contrast media injection or radio-clinical method with a simple chest X-ray followed by a rapid infusion of physiological serum
Detailed description
The use of CVC is part of daily life in onco-hematology, particularly for chemotherapy treatments in the Day Unit (DU). Among the possible complications and dysfunctions, the most frequent is the lack of CVC blood return, which can be responsible for a disorganization of the patient's management in the Day Unit (delay in patient management). In this study, the 2 most commonly used schemes are compared in a randomised multicentre study. The first scheme is a radiological circuit with opacification using contrast media injection. The second scheme is radio-clinical with a chest X-ray to check the correct functioning of the CVC followed by a rapid infusion of physiological serum. The patient management is compared for the two schemes in term of delay (delay from start to end time of patient management). The safety and the cost of both schemes is compared.
Interventions
PROCEDUREPhysiological serum injection
In case of lack of CVC blood return, Physiological serum is injected in the CVC after Chest X-Ray
PROCEDUREContrast agent injection
In case of lack of CVC blood return, Contrast agent is injected in the CVC after Chest X-Ray

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Compare the delay between randomisation (determination of the lack of blood return) and the decision to initiate or not the chemotherapy protocol on the same day, for both procedures | 1 day | Time between randomisation and the decision to initiate or not the chemotherapy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluate the frequency of recurrence of lack of CVC blood return | 3 months | Number of new events of lack of CVC blood return |
| Evaluate the frequency of recurrence of new re-opacification events | 3 months | Number of new CVC re-opacification events |
| Evaluate the frequency of CVC replacement | 3 months | Number of new catheter replacements |
| Medico-economic evaluation of both procedures | 3 months | Average cost of the patient management for each procedure |
| Assess allergic reactions | 24 hours | Number of Allergic reactions requiring at least oral therapy |
| Assess renal impairment | 28 days | Increase in creatinine to \> 1.5 times the most recent screening value |
| Assess the treatment delay due to CVC blood return | 1 day | Number of CVC blood return that led to delay the treatment to the day after |
| Quantify systemic CVC infectious complications | 14 days | Number of Systemic CVC infectious complications |
