Infection Related to Short-term Central Venous Catheters

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the incidence of infection of short-term central venous catheters by comparing different cannulation techniques (by anatomical references and under ultrasound control) and according to the experience of the operator in patients undergoing elective surgery. A prospective observational study will be carried out in which all scheduled surgery patients who have a central venous line inserted for one month will be included. Those under 18 years of age, patients with catheters lasting more than 14 days and those who do not sign the informed consent will be excluded from this study. A chest X-ray will be performed on all patients in order to diagnose possible complications associated with the technique and, only in case of suspected infection, culture of the catheter tip and blood cultures of blood obtained from the catheter and peripheral blood will be requested.

Detailed Description
-----------------
A prospective observational study will be carried out. The maximum time between the intervention and the final evaluation will be 21 days, since the study evaluates the infection related to short-term catheters and its probable improvement after the removal of the device. All patients undergoing elective surgery who have a central venous line inserted for three months will be included in the study. Those under 18 years of age, patients with catheters lasting more than 14 days and those who do not sign the informed consent will be excluded. A follow-up of the central venous catheters that are inserted in those patients scheduled for surgery who have an indication for it will be carried out. The criteria for choosing the access route will be carried out according to the usual clinical practice of the responsible anesthesiologist. The asepsis measures that will be carried out both in the insertion and in the maintenance of the catheter will be those used on a regular basis, which follow the recommendations of the guidelines for the prevention of infections related to intravascular catheters of the American Center for Control and Prevention. of Diseases.
