Infection Related to Short-term Central Venous Catheters

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 12 months 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.
