Research Article: The influencing factors of postoperative sleep disorders in elderly patients undergoing hip replacement surgery under general anesthesia and the construction and validation of a nomogram prediction model
Abstract:
To explore the influencing factors of postoperative sleep disorders in elderly patients undergoing hip replacement (HR) under general anesthesia, and to construct and validate a nomogram prediction model.
A total of 329 patients who underwent general anesthesia HR surgery in our hospital from December 2021 to December 2023 were retrospectively gathered and grouped into a modeling group (230 cases) and a validation group (99 cases). The modeling group was separated into a sleep disorder group and a no sleep disorder group based on postoperative sleep disorders.
Out of 230 patients, 69 experienced sleep disorders, with an incidence rate of 30.00%. Multivariate logistic regression found that age, anesthesia time, surgery time, intraoperative blood loss, postoperative hypoxemia, postoperative VAS score, and postoperative CRP level were risk factors for postoperative sleep disorders in elderly HR patients undergoing general anesthesia ( p <?0.05). The AUC of the modeling group and validation group was 0.978 and 0.972, and the H-L test showed ? 2 =?7.410 and 7.342, respectively, p =?0.762 and 0.752, indicating good consistency. DCA curve showed that when the high-risk threshold probability was between 0.08 and 0.88, the nomogram model had high clinical value.
Age, anesthesia time, surgery time, intraoperative blood loss, postoperative hypoxemia, postoperative VAS score, and postoperative CRP level are the influencing factors of postoperative sleep disorders in elderly HR patients undergoing general anesthesia. The nomogram model constructed based on this has good discrimination and consistency, and can predict the postoperative sleep disorders of patients.
Introduction:
Accompanying the trend of population aging, elderly hip joint diseases have become a clinical concern, with an evident increase in the risk of hip fractures, osteoarthritis, and other hip joint diseases among the elderly population ( 1 ). Hip replacement (HR) surgery is a primary clinical treatment method for hip joint diseases, which can reconstruct the patient’s hip joint function, control the progression of the disease, and improve the patient’s quality of life ( 2 ). However, the elderly patients’ various…
