Analysis of risk factors for perioperative mortality in elderly patients with intertrochanteric fracture.

Abstract

To investigate risk factors for perioperative death in elderly patients with intertrochanteric fracture. Clinical data from 1051 cases with intertrochanteric fracture from March 2005 to March 2015 were reviewed and analyzed, and causes of death during the perioperative period were statistically analyzed. Various indicators were compared by t test and χ² test. Multivariate analysis was performed using non-conditional logistic regression analysis. Chronic diseases of major organs (heart, brain, and lung), postoperative complications, and various indicators within 24 h after admission (albumin, hemoglobin, brain natriuretic peptide [BNP], glucose, creatinine, arterial blood pH, PaO², and APACHE II) were statistically significantly different between patients who survived and those who died. Logistic regression analysis indicated that postoperative complications, APACHE II score, BNP, and chronic diseases of major organs were the risk factors for perioperative mortality in elderly patients with intertrochanteric fracture. BNP and APACHE II score could be used as important reference indexes for predicting possible perioperative mortality in elderly patients with intertrochanteric fracture and chronic diseases of major organs. Complications after fracture may be also risk factors.
