Pdf Summary

This study aimed to investigate whether the recovery time of percutaneous oxygen saturation (SpO2) after stair climbing can be a predictor of postoperative respiratory complications following lobectomy. The study involved patients who underwent lobectomy for non-small cell lung cancer between January 2015 and February 2023. The patients underwent a stair-climbing test where their pulse and SpO2 levels were recorded using a pulse oximeter. The SpO2 recovery time was defined as the time required for the SpO2 levels to recover from the minimum to its resting value after stair climbing. Postoperative respiratory complications were evaluated using the Clavien-Dindo classification.<br /><br />The results showed that patients who had a delayed recovery time of SpO2 after stair climbing were more likely to experience postoperative respiratory complications. The optimal cut-off value for the SpO2 recovery time for predicting complications was determined to be 90 seconds. The analysis also showed that factors such as age, smoking status, and preoperative respiratory function were not significantly associated with the occurrence of complications.<br /><br />In conclusion, the delayed recovery time of SpO2 after stair climbing was found to be a predictor of postoperative respiratory complications following lobectomy. Monitoring SpO2 levels after stair climbing could provide useful clinical information for identifying patients at risk of complications.
