Objective:

To develop and validate a nomogram prediction model for forecasting postoperative hypoxemia within 24 hours after laparoscopic sleeve gastrectomy in obese patients, emphasizing the urgency of timely interventions.

Key Findings:
  • Postoperative hypoxemia is a common complication following laparoscopic sleeve gastrectomy, with an incidence rate potentially reaching 80%, highlighting the need for effective prediction models.
  • The developed nomogram effectively predicts hypoxemia risk, allowing for early identification of high-risk patients, which can significantly improve postoperative care.
Interpretation:

The predictive model can enhance surgical safety and postoperative recovery by facilitating timely interventions for patients at risk of hypoxemia.

Limitations:
  • The study is retrospective, which may introduce biases such as selection bias and information bias.
  • Data were collected from a limited number of centers, potentially affecting the generalizability of the findings to broader populations.
Conclusion:

The nomogram developed in this study serves as a valuable tool for predicting postoperative hypoxemia in obese patients undergoing laparoscopic sleeve gastrectomy, potentially improving patient outcomes and enhancing surgical safety.
