Correlation between pre-anesthesia anxiety and emergence agitation in non-small cell lung cancer surgery patients.

Abstract

Background: Preoperative anxiety is a common emotional problem during the perioperative period and may adversely affect postoperative recovery. Emergence agitation (EA) is a common complication of general anesthesia that may increase patient discomfort and hospital stay and may be associated with the development of postoperative complications. Pre-anesthetic anxiety may be associated with the development of EA, but studies in this area are lacking.

Aim: To determine the relationship between pre-anesthetic anxiety and EA after radical surgery in patients with non-small cell lung cancer (NSCLC).

Methods: Eighty patients with NSCLC undergoing surgical treatment between June 2020 and June 2023 were conveniently sampled. We used the Hospital Anxiety and Depression Scale's (HADS) anxiety subscale (HADS-A) to determine patients' anxiety at four time points (T1-T4): Patients' preoperative visit, waiting period in the surgical waiting room, after entering the operating room, and before anesthesia induction, respectively. The Riker Sedation-Agitation Scale (RSAS) examined EA after surgery. Scatter plots of HADS-A and RSAS scores assessed the correlation between patients' pre-anesthesia anxiety status and EA. We performed a partial correlation analysis of HADS-A scores with RSAS scores.

Results: NSCLC patients' HADS-A scores gradually increased at the four time points: 7.33 ± 2.03 at T1, 7.99 ± 2.22 at T2, 8.05 ± 2.81 at T3, and 8.36 ± 4.17 at T4. The patients' postoperative RSAS score was 4.49 ± 1.18, and 27 patients scored ≥ 5, indicating that 33.75% patients had EA. HADS-A scores at T3 and T4 were significantly higher in patients with EA (9.67 ± 3.02 vs 7.23 ± 2.31, 12.56 ± 4.10 vs 6.23 ± 2.05, P < 0.001). Scatter plots showed the highest correlation between HADS-A and RSAS scores at T3 and T4. Partial correlation analysis showed a strong positive correlation between HADS-A and RSAS scores at T3 and T4 (r = 0.296, 0.314, P < 0.01).

Conclusion: Agitation during anesthesia recovery in patients undergoing radical resection for NSCLC correlated with anxiety at the time of entering the operating room and before anesthesia induction.
