The Integrated Pulmonary Index (IPI) predicted PACU hypoxemia in elderly patients with an AUC of 0.843, sensitivity of 85.42%, and specificity of 72.22%.
Does the Integrated Pulmonary Index (IPI) predict PACU hypoxemia in elderly patients after general anesthesia?
The Integrated Pulmonary Index (IPI) is an independent predictor of post-anesthesia care unit hypoxemia in elderly patients after general anesthesia, with an optimal cut-off value of 7.5.
Absolute Event Rate: 0% vs 0%
Aims/Background Elderly patients are at increased risk of hypoxemia in the post-anesthesia care unit (PACU) after general anesthesia. The Integrated Pulmonary Index (IPI) may have predictive value in identifying these patients. This study aimed to investigate the predictive value of the IPI for PACU hypoxemia in elderly patients after general anesthesia. Methods A retrospective analysis was conducted on 276 patients who underwent general anesthesia surgeries at Zhongshan Hospital, Fudan University, between December 2021 and December 2024. Patients were divided into a PACU hypoxemia group (n = 96) and a non-PACU hypoxemia group (n = 180). Univariate and binary logistic regression analyses were used to determine influencing factors, and a receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predictive value of IPI for PACU hypoxemia in elderly patients after general anesthesia. Results Binary logistic regression analysis revealed that IPI was an independent influencing factor of PACU hypoxemia in elderly patients (p 7.5 was significantly higher than that of patients with IPI ≤7.5 (p < 0.05). Conclusion IPI demonstrates a certain predictive value of PACU hypoxemia in elderly patients after general anesthesia.
