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 complications following lobectomy for non-small cell lung cancer (NSCLC). The researchers retrospectively identified patients who underwent lobectomy at their hospital between January 2015 and February 2023, and who were indicated for the stair-climbing test (SCT) according to American College of Chest Physicians (ACCP) guidelines. The SCT involved climbing 64 steps and measuring the SpO2 recovery time, defined as the time required to recover from the minimum value to its resting value after stair-climbing. The occurrence of postoperative respiratory complications within 30 days after surgery was the primary consideration.<br /><br />Among the 54 patients who performed the SCT and underwent lobectomy, comorbidity was found in 96.2% of patients, with chronic obstructive pulmonary disease or interstitial pneumonia being the most frequent. Grade 2 or greater postoperative respiratory complications were seen in 20.4% of patients. There was a correlation between delayed SpO2 recovery time and increased complications. The receiver operating characteristic (ROC) curve analysis yielded a cut-off value of 90 seconds for predicting postoperative respiratory complications.<br /><br />In univariate logistic regression analyses, a SpO2 recovery time of 90 seconds or longer was a predictor of postoperative respiratory complications, with an odds ratio of 11.6.<br /><br />The findings suggest that delayed recovery time of SpO2 after stair-climbing can be a predictor of postoperative respiratory complications following lobectomy. Monitoring SpO2 after stair-climbing can provide useful clinical information for assessing postoperative risks in NSCLC patients. This information may help in identifying patients who are at higher risk for complications and may require additional interventions to optimize their outcomes.
