Preoperative Intervention to Reduce Delirium After Cardiac Surgery

Preoperative Cognitive Therapy Intervention in Reducing Delirium After Cardiac Surgery

This research is designed for experimental quantitative research and is conducted by simple random sampling. Both the control group and the experimental group provided preoperative routine nursing treatment and preoperative medical teaching manuals. The latter adds cognitive therapy and gamification evaluation. Both groups used CAM-ICU to assess the occurrence and duration of postoperative delirium, and DRS-R-98 was used to assess the severity of delirium. After collection, use SPSS 22.0 statistical software package for analysis and processing. The expected result is that the incidence of delirium, the duration of delirium, and the severity of delirium in the experimental group were significantly lower than those in the control group.

This study is an experimental quantitative research design. Both the control group and the experimental group provide routine nursing treatment and preoperative medical teaching manuals before surgery. The latter adds cognitive therapy and gamification evaluation of "Postoperative Care and Environmental Image Data Explanation". The two groups used CAM-ICU to assess the occurrence and duration of delirium after surgery, and DRS-R-98 was used to assess the severity of delirium. From 2021 to 2022, a simple random sampling method is adopted for patients undergoing cardiac surgery in the intensive care unit of a medical center in Central Taiwan, and a lottery is drawn on the first day of each month to determine the belong to which group in the current month. There were 55 persons in each group, and all subjects had no cognitive impairment. After the collected, it was analyzed and processed with SPSS 22.0 statistical package software.

Expected results: The incidence of delirium, the duration of delirium, and the severity of delirium in the experimental group were significantly lower than the control group.

Inclusion Criteria:

• Expected to undergo traditional thoracotomy or minimally invasive surgery for cardiac surgery.
• No cognitive impairment before surgery.

Exclusion Criteria:

• Diagnosed with aortic dissection.
• Previously admitted to the intensive care unit.
