El ultrasonido en tiempo real se ha convertido en una herramienta invaluable debido a su seguridad, disponibilidad y proporciona información detallada en relación con la anatomía de los órganos internos, en la colocación de catéteres venosos centrales favorece las tasas de éxito y disminuye el número de complicaciones.  OBJETIVO: determinar si la colocación de catéter venoso central guiado por ultrasonido en tiempo real disminuye el número de complicaciones en comparación con la técnica por referencias anatómicas.  MATERIAL Y MÉTODO: estudio observacional, ambispectivo, longitudinal en el que se seleccionaron adultos mayores de 18 años de edad que requirieron un catéter venoso central durante su hospitalización en el Hospital General Naval de Alta Especialidad (HOSGENAES) guiado por ultrasonido en tiempo real y por referencias anatómicas de enero de 2014 a febrero de 2016. Los datos se recabaron de los expedientes clínicos siempre y cuando estuvieran completos. Las variables observadas fueron el tipo de complicaciones, tipo de catéter, sitio de inserción, operador experto, servicio que instaló los catéteres venosos centrales, si fue de primera vez o subsecuente, número de intentos, accesos exitosos y los diagnósticos de ingreso, edad, género e índice de masa corporal.  RESULTADOS: se incluyeron 464 pacientes de los que 351 (76%) fueron guiados por referencias anatómicas y en 113 (24%) por ultrasonido en tiempo real. Se reportaron 211 complicaciones, 84% en el grupo de referencias anatómicas y 16% en el grupo de ultrasonido en tiempo real con razón de momios (OR) de 2.36. La complicación más frecuente fue la de tipo mecánica, principalmente la mala colocación, en el grupo de referencias anatómicas representó 51% versus 12% en el grupo de ultrasonido en tiempo real con OR de 9.5. El 100% de los catéteres venosos centrales guiados por ultrasonido en tiempo real fueron exitosos vs 87% de los guiados por referencias anatómicas.  CONCLUSIONES: el ultrasonido en tiempo real mejora las tasas de éxito, reduce el número de intentos y disminuye las complicaciones asociadas con la inserción de un catéter venoso central.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  BACKGROUND: The placement of central venous catheter (CVC) is an essential part in the management of patients in many clinical scenarios. Ultrasonography in real time (USRT) has become an invaluable tool because of its safety and availability and provides detailed information regarding the anatomy of the internal organs, in the placement of central venous catheters (CVCs) encouraging success rates and decreasing the number of complications.  OBJECTIVE: To determine whether the placement of central venous catheter guided by real-time ultrasound decreases the number of complications compared with the technique for anatomical references.  MATERIAL AND METHOD: An observational, retrospective and prospective, longitudinal study was done selecting adults over 18 years old who required a CVC during their hospitalization at the Naval General Hospital of High Specialty (HOSGENAES), Mexico City, led by USRT and anatomical references from January 2014 to February 2016. Data were gathered from the files provided they were complete. The variables observed were the kind of complications, type of catheter insertion site, skilled operator, service that installed the CVCs, if it was first or subsequent, number of attempts, successful access and admission diagnoses, age, gender and body mass index (BMI).  RESULTS: Four hundred sixty-four patients were included, of which 351 (76%) were guided by anatomical and 113 (24%) by USTR references. A total of 211 complications occurred; 84% in the group of anatomical references and 16% were reported in the group USTR with OR of 2.36. The most common complication was mainly mechanical type misplacement accounting for 51% in the group of anatomical references versus 12% in the USRT with OR of 9.5375. The 100% of CVCs guided by USTR were successful vs 87% guided by anatomical references.  CONCLUSIONS: Ultrasonography in real time improves success rates, reduces the number of attempts and reduces complications associated with the insertion of a central venous catheter.]]></p></abstract>
