estudio descriptivo, con abordaje cuantitativo, de validación metodológica de instrumento. Se siguieron tres etapas: elaboración del instrumento; validación del contenido del protocolo según técnica de Delphi y concordancia entre expertos y la literatura científica.

Resultados:

en base a la validación del contenido, se elaboró un protocolo referido a la atención de pacientes en uso de DAV, evaluado por expertos/jueces españoles. De los 15 ítems evaluados, mediante el índice de Validez de Contenido (IVC), 10 de ellos presentaron fuerte evidencia de validación con Kappa, variando entre 0,87 y 1.

Conclusión:

el método permitió validar intervenciones que contribuirán a una atención calificada y uniforme a pacientes en uso de DAV.

Action	Description
1. Clarification of the patient in relation to the risk-benefit ratio of the device	Aimed at providing humanized care and reducing patient anxiety
2. Equipment functionality monitoring	Prevention of console-related problems. Prevention of possible obstruction of the system.
3. Monitoring: HR, MAP, RAP, LAP, CO, HI, SvO₂.	Aimed at obtaining appropriate monitoring and clinical compensation.
4. Monitoring of pulse oximetry, urine output, temperature.	Aimed at obtaining appropriate monitoring and clinical compensation.
5. Use of pressure relief mattresses to prevent pressure ulcers.	Redistribute and soften the pressure of a body on a surface and prevent skin injuries.
6. Maintenance of the patient in horizontal decubitus position and contraindication of changing of decubitus.	Avoid obstruction and/or rupture in the system used by the device.
7. Assessment of laboratorial exams such as gasometry, creatinine, urea, lactate, sodium, potassium, magnesium: 6∕6 hours.	Analyze the occurrence of adverse prognoses, such as renal and respiratory changes and ineffective tissue perfusion.
8. Collection of total proteins and albumin, control of bilirubin, liver enzymes and amylase, fibrinogen and D-dimer: daily.	Analyze the occurrence of liver complications and coagulopathies.
9. Administration of prophylactic antibiotic therapy during the seven first days as prescribed.	Perform the prophylaxis of infections related to the surgical wound.
10. Collection of tracheal secretion culture and surgical wound culture: in case of presence of secretion.	Identify microorganisms that cause infections in the surgical wound for an appropriate antibiotic therapy, if necessary.
