Effect of Spirometry Use in the Pre-Op Period on Stress and Anxiety Levels in the Post-Op Period in Total Hip Replacement and Knee Replacement Surgeries: A Quantitative Quasi-Experimental Study

Objective: This research aimed to determine the effect of preoperative use of spirometer on stress and anxiety levels in the postoperative period in total hip replacement and knee replacement surgeries. Material and Methods: The study was carried out in a quasiexperimental design. The study was conducted in the orthopaedic clinic of İstanbul Gaziosmanpaşa Training and Research Hospital in June 2022, in İstanbul, with 30 patients with hip prostheses (n=17) and knee prostheses (n=13). Spirometry was used after the Perceived Stress Scale (PSS), and the Beck Anxiety Inventory (BAI) was applied preoperatively, and the PSS, and the BAI was applied again postoperatively. Results: In intra-group comparisons, a decrease was observed in the anxiety scores of patients with hip and knee prostheses (p=0.000). In inter-group comparisons, there was a difference in the postoperative BAI scores, while there was a difference in the preoperative and postoperative PSS scores (p<0.01). A positive relationship was detected between postoperative PSS and the BAI of those in the hip replacement group (r=0.493; p=0.044). Conclusion: The results demonstrated that preoperative use of spirometer can reduce patients' stress and anxiety levels. Providing education to patients and their families before and after surgery can be recommended to enable them to resume their daily life activities.
