Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• Changes in the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) scale

  Changes in the scale for the diagnosis of delirium in critical care units were assessed previous and post intervention of visual material projection. The final CAM-ICU-7 score ranges from 0-7 with 7 being most severe. CAM-ICU-7 scores were further categorized as 0-2: no delirium, 3-5: mild to moderate delirium, and 6-7: severe delirium.

  2 times, previous and post intervention, in the first 24 hours after cardiac surgery. This method is applied individually, through study completion, in an average of 1 year.

• Mini-Mental State Examination (MMSE) scale

  Initially, regardless of the group to which they belonged, all patients were administered the MMSE scale to assess their initial cognitive state and their sociodemographic and anthropometric data were collected. The maximum score for the MMSE is 30. A score of 25 or higher is classed as normal. If the score is below 24, the result is usually considered to be abnormal, indicating possible cognitive impairment.

Study Arms (2)

Control group

EXPERIMENTAL

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.

Behavioral: the usual unit treatment

Intervention group

ACTIVE COMPARATOR

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.

Interventions

Projection of Visual Material on Postoperative Delirium in Patients Undergoing Cardiac Surgery BEHAVIORAL

Patients are randomized into two groups (control group and intervention group). Initially, all patients are administered the "Mini-Mental State Examination scale" (MMSE) to assess their initial cognitive state and their sociodemographic and anthropometric data. 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. In the control group, after the surgical intervention and 30 minutes after the patient's extubation the CAM-ICU scale is administered.

Intervention group

the usual unit treatment BEHAVIORAL

CAM-ICU scale is administered to the Control group. No visual material is used.

Control group
