Preoperative Anxiety and Its Postoperative Associated Factors in Patients Receiving Post Anesthetic Recovery Care at Surgical Intensive Care Unit

Abstract

Objectives: This study determined the postoperative associated factors with preoperative anxiety in patients receiving post anesthetic recovery care at surgical intensive care unit. Methods: In this cross-sectional correlational study, 84 postoperative patients were admitted to a surgical intensive care unit for post anesthetic recovery care. Participants completed questionnaires on anxiety, pain, stress, and sleep disturbance on the preoperative day and on the morning of postoperative day 1. Data were analyzed with χ 2 -test, unpaired t-test, Pearson correlation analysis and logistic regression. Results: Forty patients (47.6%) had a high preoperative anxiety score of ≥ 18. Higher preoperative anxiety was associated with greater postoperative anxiety (r = 0.24, <i>p</i> = 0.026), higher postoperative stress (r = 0.24, <i>p</i> = 0.026), and poorer postoperative sleep (r = 0.39, <i>p</i> < 0.001). High preoperative anxiety was associated with postoperative physical restraint (B = 1.72, OR: 5.59, 95% CI: 1.19-21.32). High preoperative anxiety was associated with postoperative sleep disturbance (B = 0.29, OR: 1.34, 95% CI: 1.08-1.65). Conclusions: High preoperative anxiety is associated with poorer sleep during the first postoperative night among surgical intensive care unit patients.
