Análisis de la utilización de Los catéteres Intravenosos periféricos de Linea Media Frente a Los catéteres Intravenosos periféricos Convencionales en el Servicio de Medicina Interna

Brief Summary

Detailed Description

A randomized, longitudinal experimental study is designed, which will allow comparisons to be made between the results obtained in the experimental group and the control group. The study will be carried out in the Internal Medicine and medium and long stay unit of the CHGUV, during the period of time necessary to complete the required sample size, which has finally been established at six months. When the patient is admitted to our unit, a number is assigned from the admission service, based on their admission order; this number will serve for subsequent random assignment to one another group. In this case, the use of a website to generate said numbers is proposed. Using established procedures for the generation of random numbers, the numbers that correspond to the subjects that are going to be part of each of the groups will be identified. The list of random numbers that will make up the experimental group has been prepared previously by the Internal Medicine Unit secretary and will be known by the person who will carry out the placement of the midline catheter (two nurses from the unit trained in the placement and handling of this type of device, who will also be those in charge of training the rest of the staff). The list will be reviewed daily in the morning shift, and those patients who have not given their informed consent will be eliminated, those in whom, due to their pathology, a brief admission is expected or patients who are in a terminal or palliative care situation, in those who consider the step of treatment to the subcutaneous route as the best option. The informed consent to participate in the study will be given to the patient and/or relatives at the time of admission, also informing them that the next morning those responsible for the study will explain the object of the study in more depth and answer their questions. Before the third day after admission, in the morning shift, the peripheral catheters will be reviewed and replaced by another peripheral catheter or by a midline catheter depending on the group to which the patient has been assigned. In case of being a patient assigned to the experimental group, the midline catheter will be placed by personnel trained for it. The procedures for inserting and maintaining the catheters are already established in the unit and will be those that will be followed during the study, depending on the type of catheter; The care in the insertion and maintenance of midline catheters does not differ from the care of peripherally inserted central catheters, since they require a sterile technique; therefore, although the insertion of the midline catheters will be done by the selected investigators, maintenance will be performed by the unit's staff, following, as we have indicated, the procedures already established. When the patient requires a change of venous access for whatever reason, it will be replaced by the same type of catheter (midline or conventional catheter) and the necessary information will be added to the information record sheet.
