About

The aim is to evaluate the impact of visual projection of images of relatives or loved ones in patients undergoing cardiac surgery in the immediate postoperative period, and its influence on the incidence and development of postoperative delirium.

A randomized, double-blind clinical trial was designed in the immediate postoperative period of adult patients undergoing cardiac surgery. CONSORT guidelines were followed.

A control group and an intervention group were established. In the intervention group, the patients underwent a visual projection, while the usual unit treatment was carried out with the control group. Sociodemographic, anthropometric, anesthetic, and surgical variables were also recorded. The postoperative delirium assessment scale used was the "Confusion Assessment Method for the Intensive Care Unit scale" (CAM-ICU).

The projection of visual material could reduce the incidence of postoperative delirium in patients undergoing cardiac surgery, although it cannot be established that it is effective as a treatment once the pathology is already established.

The results obtained suggest that the visual projection of images is an effective and economical tool to address an increasingly incidental problem due to the aging of the population.

---

105 participants in 2 patient groups

Control group

Experimental group

Description:

In the control group, after the surgical intervention and 30 minutes after the patient's extubation the CAM-ICU scale is administered, recording its value as R0. The following day, at 9:00 a.m., another nurse uses the CAM-ICU scale, noting its value as R1. If postoperative delirium was detected during the day and night, the unit's usual treatment was followed: administration of haloperidol and/or dexmedetomidine.

Treatment:

Behavioral: the usual unit treatment

Intervention group

Active Comparator group

Description:

In the intervention group, patients and/or companions are asked to provide visual material, which could consist of photographs of loved ones and/or places known to the patient. 30 minutes after the extubation of the patients, the CAM-ICU scale is administered, recording its value as R0. At night, the projection of images provided by the patient are replaced by a nocturnal visual projection (night sky with stars and moon), ensuring that the patient is able to identify that it was nighttime. Finally, at 9:00 a.m., a nurse who had not worked at night and therefore did not know which patients had received the intervention, administers the CAM-ICU scale again, recording its value as R1.
