Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Incidence of delirium within 72 hours after coronary artery bypass graft surgery. Timepoint: Delirium will be assessed the night before surgery (as baseline), immediately after the patient’s transfer to the cardiac intensive care unit, and then daily up to 72 hours following coronary artery bypass graft surgery. Method of measurement: Delirium will be evaluated using the Intensive Care Delirium Screening Checklist by a nurse blinded to the intervention type. This tool consists of 8 items (altered level of consciousness, inattention, disorientation, hallucination-delusion-psychosis, psychomotor agitation or retardation, inappropriate speech or mood, sleep/wake cycle disturbance, and symptom fluctuation) used to diagnose delirium in patients admitted to the intensive care unit.;Severity of pain within 72 hours after coronary artery bypass graft surgery. Timepoint: Pain intensity will be measured the night before surgery (as baseline), immediately after the patient’s transfer to the cardiac intensive care unit, and then at 6, 12, 24, 48, and 72 hours following coronary artery bypass graft surgery. Method of measurement: Pain intensity will be measured using the Numeric Pain Rating Scale. The patient selects a number between zero (no pain) and 10 (worst possible pain) and circles it. Additionally, the location of pain and the amount of opioid consumption will be recorded.;Severity of nausea and vomiting within 72 hours after coronary artery bypass graft surgery. Timepoint: Nausea and vomiting intensity will be measured the night before surgery (as baseline), immediately after the patient’s transfer to the cardiac intensive care unit, and then at 6, 12, 24, 48, and 72 hours following coronary artery bypass graft surgery. Method of measurement: The intensity of nausea and vomiting will be measured using the Numeric Nausea and Vomiting Scale. The patient selects a number between zero (no nausea and vomiting) and 10 (worst possible nausea and vomiting) and circles it. | — |
