Trombosis y obstrucción asociadas a vías venosas centrales. Incidencia y factores de riesgo

Factores que condicionan el desarrollo de trombosis venosa en pacientes con catéter venoso central ingresados en la unidad de cuidados intensivos del hospital de niños Roberto Gilbert Elizalde

“…Although the femoral route has been identified as a risk factor for thrombosis, occurring in 90% [5], this finding was not corroborated in the present study. All central venous catheters were bilumen, similar to those found in a reference study in which the number of lumens was a risk factor for thrombosis, in contrast to other studies [5]. In previous studies, complications associated with CVC were higher when it was placed by less experienced specialists [10]; however, this association could not be verified in this study.…”

“…These results coincide with those published in a 2015 study in Bogotá by Vargas-Ureña which reported that the most frequent location was the femoral vein (41.5%) followed by the subclavian vein (27.1 %) [8]. Although the femoral route has been identified as a risk factor for thrombosis, occurring in 90% [5], this finding was not corroborated in the present study. All central venous catheters were bilumen, similar to those found in a reference study in which the number of lumens was a risk factor for thrombosis, in contrast to other studies [5].…”

“…The total number of children in whom central venous catheter-associated thrombosis was diagnosed was 14%, a result that differs from those reported at the regional level, which range from 22% to 34.1% [6,7]. In Europe, the frequency is 1.18% [5]. Thrombosis occurred more frequently in preschool children, which differs from previous publications that re-port a higher risk in children under 1 year and over 12 years [1].…”

“…Central venous accesses are widely used during the treatment of patients with various diseases since 1952 when Aubaniac described the cannulation of a central vein, the subclavian. Currently, they constitute a common procedure in Pediatric Intensive Care Units (PICU) [5]. Regarding the incidence of thrombosis, it is highly variable, from 0.6% to 50% depending on whether symptomatic thromboses are detected or an active search is carried out with radiological methods.…”

“…Regarding the incidence of thrombosis, it is highly variable, from 0.6% to 50% depending on whether symptomatic thromboses are detected or an active search is carried out with radiological methods. Thus, Becket al, [6] in a study carried out in a PICU, reported a rate of 18% of catheters after conducting an active search and recently, Karapinar and Cura report a 2.2% incidence of thrombosis with implanted catheters in critically ill children [5].…”
