ORIGINAL ARTICLEPreoperative Mild Cognitive Dysfunction Predicts Pulmonary Complications After Coronary Artery Bypass Graft Surgery
Section snippets
Methods
The trial was approved by the institutional research and ethical committee at the authors’ institution. Informed consent was obtained from each patient.
The authors separated 48 patients>70 years old who were scheduled to undergo elective coronary artery bypass graft (CABG) surgery into two groups. Group A (n = 25) comprised patients with preoperative mild cognitive impairment. Group B (n = 23), the control group, consisted of patients with no cognitive impairment.
After premedication, anesthesia
Results
The patient demographics and the risk factors of the study groups were similar (p>0.05) (Table 1). No revision because of bleeding was needed in any of the patients. The preoperative mean MoCA score was 19.25±2.1 in group A and 27.16±1.3 in group B (p = 0.036) (Table 2).
The rate of postoperative atelectasis detected on postoperative day 3 was 84% in the group with preoperative mild cognitive impairment (group A) and 17% in the control group. The difference between the groups was statistically
DIscussIon
Approximately 1 million CABG procedures are performed worldwide every year.9 Postoperative pulmonary complications are the most frequent and significant contributor to morbidity, mortality, and costs associated with hospitalization.10, 11, 12 Every clinician familiar with the postoperative care of patients undergoing cardiac surgery anticipates pulmonary complications.13
Many different factors may cause pulmonary complications after cardiac surgeries. Preoperative risk factors include chronic
Conclusions
Mild cognitive impairment is associated with pulmonary complications after CABG. Atelectasis was the most commonly detected complication in patients with cognitive impairment in the preoperative period.
